I. Article 20a GG

Since August 1, 2002, animal protection has been enshrined as a state objective in Article 20a of the Grundgesetz, thereby acquiring constitutional status.Footnote ²⁴ This was achieved by amending the existing provision to include the words “and the animals,” explicitly elevating animal welfare to the constitutional level. The provision reads:

The amendment was intended to reflect “the ethical responsibility of humans in their treatment of animals.”Footnote ²⁶ To balance the interests of animal use with the need to protect animals from suffering, harm, or pain, it was deemed necessary to elevate animal protection within the legal hierarchy. The stated purpose of the constitutional amendment was to grant ethical animal protection constitutional status, thereby strengthening the effectiveness of the statutory provisions of the Tierschutzgesetz. This constitutional upgrade was not merely symbolic. Certain provisions of the Tierschutzgesetz restrict absolute fundamental rights, which, under Germany’s constitutional framework, can only be limited by competing constitutional interests.Footnote ²⁷ Without the explicit inclusion of animal protection in the Constitution, such provisions would have lacked a constitutional counterweight, rendering them unconstitutional.Footnote ²⁸

Beyond its role in resolving constitutional conflicts, Article 20a GG also serves as a guiding principle for the interpretation of indeterminate legal terms in a constitutionally compliant manner. Animal protection is now recognized as a “paramount public interest.”Footnote ²⁹ The provision embodies a pathocentric approach,Footnote ³⁰ emphasizing the welfare of animals based on their capacity to suffer. Yet, while Article 20a GG is a legally binding constitutional norm, ^{Footnote 31} its practical impact in the field of animal protection law is generally considered limited.Footnote ³² The provision falls under the category of a state objective clause, Staatszielbestimmung, a type of constitutional norm that imposes a legally binding duty on state authorities to continuously consider and fulfill specific objectives. State objective clauses set out a legislative agenda and serve as a directive for government action, including the interpretation of statutes and other legal provisions.Footnote ³³ While all state organs are bound by such provisions, their primary addressee is the legislature, which is tasked with translating the constitutional mandate into concrete statutory provisions.Footnote ³⁴ However, state objective clauses generally impose only a broad obligation to pursue a particular goal without dictating the specific means by which it must be achieved. As a result, they are considered purely objective legal norms that do not confer subjective rights. Given the broad legislative discretion in implementing state objectives, they are not directly justiciable.Footnote ³⁵ Nonetheless, the Federal Constitutional Court, Bundesverfassungsgericht, retains the authority to review whether the minimum constitutional requirements set by Article 20a GG have been met.Footnote ³⁶ In practice, however, the legislature can sidestep its obligations through a strategy akin to legislative evasion,Footnote ³⁷ effectively weakening the enforcement of the Tierschutzgesetz. The broad margin of discretion granted to lawmakers has resulted in Article 20a GG being rarely, if ever, subject to judicial enforcement in the realm of animal law. Despite its formally binding nature, the provision arguably functions more as “soft law” than as a robust constitutional guarantee.Footnote ³⁸ Nonetheless, the constitutional recognition of animal protection underscores its ethical and legal significance, providing a framework for balancing competing interests within the legal system.

II. Animal Protection Act

Complementing this constitutional framework is the Tierschutzgesetz, first enacted in 1972 and subsequently amended numerous times to reflect evolving societal values.Footnote ³⁹ The Act is rooted in a pathocentric philosophy, prioritizing the prevention of suffering and the promotion of animal welfare for the sake of the animals themselves. Unlike frameworks that justify animal protection primarily through its benefits to humans, the Tierschutzgesetz explicitly places the intrinsic value of animals at the forefront. This approach—referred to as ethically oriented animal protection—was first codified in Germany and remains a defining feature of its legal framework.Footnote ⁴⁰ From a comparative perspective, this ethical orientation distinguishes the German model from legal frameworks such as the U.S. Animal Welfare Act, which primarily regulates animal treatment in contexts where animals serve human interests. It is designed with an anthropocentric orientation. By contrast, the German approach recognizes animal welfare as an independent legal concern, not merely an extension of human-centered interests.

Section 1 of the TierSchG, which provides the guiding principle for the entire statute, explicitly states: “The purpose of this Act is to protect the life and well-being of animals as fellow creatures, arising from human responsibility for them. No one may inflict pain, suffering, or harm on an animal without reasonable cause.”Footnote ⁴¹ Thus, unlike ecocentric environmental statutes, which focus on ecosystems or species, and anthropocentric welfare regimes such as the U.S. Animal Welfare Act, the German Animal Protection Act embodies a pathocentric logic: it centers on the prevention of suffering for individual sentient beings.

1. Substantive Provisions of the German Animal Protection Act

The German Animal Protection Act is structured into twelve parts, governing individual responsibilities in the general treatment of animals. The core provisions are found in Section 1, sentence two; Section 2; and Section 17.Footnote ⁴² Section 1 sentence two of the TierSchG establishes a fundamental principle: “No one may inflict pain, suffering, or harm on an animal without reasonable cause.”Footnote ⁴³ Section 2 of the TierSchG imposes specific duties of care on individuals who keep, care for, or are responsible for an animal. Section 17 of the TierSchG establishes criminal liability, imposing penalties of up to three years’ imprisonment or fines for killing a vertebrate without reasonable cause or inflicting pain or suffering on an animal.Footnote ⁴⁴

To fully grasp how these principles operate in practice, it is essential to analyze the structural framework of the German Animal Protection Act. At its core, Section 1 TierSchG serves as the foundational provision, embedding an overarching ethical responsibility for animal protection. This principle is reinforced by Section 2 TierSchG, which imposes a general duty of care on those who keep, care for, or are otherwise responsible for animals. Section 3 TierSchG enumerates explicit prohibitions on certain harmful actions, setting clear legal boundaries for the treatment of animals. The regulation of the lawful killing of animals is addressed in Section 4 TierSchG, which specifies the conditions under which such acts are permitted. The Act also contains provisions on medical and surgical interventions, with Sections 5 and 6 of the TierSchG outlining the permissible scope of procedures performed on animals. Further, Sections 7 to 9 TierSchG establish strict regulations on animal experimentation, ensuring that such practices are subject to rigorous ethical and legal scrutiny. Section 10 of the TierSchG regulates the role of the Animal Welfare Officer, outlining their responsibilities in overseeing compliance with animal protection standards. Due to the lack of enforceable legal positions, responsibilities are limited to advisory and recommendatory rather than a supervisory function. Section 11 of the TierSchG sets out provisions governing the breeding, keeping, and trade of animals. Meanwhile, Section 12 of the TierSchG establishes rules concerning restrictions on the transportation, movement, and keeping of animals, addressing concerns related to animal welfare during transport and in confined environments. The Act also includes detailed provisions on enforcement mechanisms. Sections 15 and 16 regulate the administrative framework for implementing the law, assigning responsibilities to authorities tasked with ensuring compliance. Criminal and administrative penalties are set out in Sections 17 and 18 TierSchG. Under Section 17 TierSchG, actions such as the unjustified killing of vertebrates or the infliction of pain or suffering constitute criminal offenses punishable by up to three years of imprisonment or fines. In contrast, Section 18 TierSchG addresses administrative offenses. Both provisions allow for the confiscation of animals involved in offenses, providing authorities with additional enforcement tools. Furthermore, Section 20 TierSchG grants courts the authority to impose bans on keeping animals in cases where an individual has been convicted under Section 17 TierSchG. These interconnected provisions form a comprehensive framework aimed at ensuring the protection and welfare of animals within Germany’s legal system.Footnote ⁴⁵

Beyond the statutory provisions of the Animal Protection Act, additional regulatory measures are introduced through various ordinances, most of which are issued by the Federal Ministry of Food and Agriculture. These ordinances serve to clarify and operationalize the statutory requirements. A key example is the Animal Welfare Livestock Ordinance (TierSchutz-Nutztierverordnung, TierSchNutztV), which, based on the enabling clause in Section 2a of the Act, provides concrete guidelines on how to apply the general duty of care under Section 2 TierSchG. In addition to statutory law and ordinances, much of the regulatory framework is influenced by expert opinions, general husbandry recommendations, and industry guidelines. While these documents are not legally binding, they are widely recognized as authoritative interpretations of best practices and serve as references for ensuring compliance with animal welfare standards. Many of these recommendations are made publicly available on the website of the Federal Ministry of Food and Agriculture.Footnote ⁴⁶

2. Enforcement and Monitoring

The Animal Protection Act is federal legislation; however, pursuant to Section 15 TierSchG, enforcement is delegated to the administrative authorities of the German states (Länder), in accordance with Germany’s federal structure and division of competences between the federal and state levels.Footnote ⁴⁷ As a result, the practical implementation of the Act depends heavily on local administrative structures and resources. The specific administrative responsibilities are generally laid down in state-level ordinances adopted by the individual states, Länder, which establish the hierarchical structure of enforcement agencies.Footnote ⁴⁸ The competent authority is typically the lower administrative authority, which includes the district administrative authority or the county office. In most German states, enforcement responsibilities fall to the local veterinary authorities, Veterinärämter, which are part of the lower administrative authority, untere Verwaltungsbehörde, typically located at the district or municipal level.

2.1. Regulatory Powers and Challenges

Under Section 16a(1) sentence 1 TierSchG, the competent authority is obligated to eliminate identified violations and prevent future breaches of the law. Specifically, Section 16a(1) sentence 2 TierSchG grants authorities the power to ensure compliance with the legal requirements outlined in Section 2 TierSchG, remove animals from their keeper when necessary, and impose bans on keeping or caring for animals.Footnote ⁴⁹

Importantly, once a violation of the Animal Protection Act has been identified, the authority does not have discretion regarding whether to act, Entschließungsermessen.Footnote ⁵⁰ Instead, it retains only discretion regarding the choice of enforcement measures, Auswahlermessen. As a result, the authority is legally obligated to respond to both existing and imminent violations.Footnote ⁵¹

However, in practice, enforcement remains highly inconsistent. Authorities often fail to utilize—or only reluctantly apply—the general enforcement clause under § 16a(1) sentence 1 TierSchG.Footnote ⁵² This reluctance does not necessarily stem from negligence or lack of intent but is often the result of structural constraints. Many authorities are chronically understaffed and underfunded, making it impossible to fulfill their statutory responsibilities adequately.Footnote ⁵³ While the scope of their duties has expanded over the years,Footnote ⁵⁴ staffing levels have remained unchanged, leading to severe resource shortages.Footnote ⁵⁵ Insufficient funding has led to a persistent shortage of official veterinarians. Additionally, decision-makers often face conflicts of interest that further undermine enforcement efforts. Municipalities, in particular, have strong economic incentives to avoid imposing burdensome regulations on local businesses. Because municipalities benefit directly from corporate success—through trade tax revenues, Section 1 GewStG, and a share of value-added tax, Umsatzsteuer Article 106(5a) GG—there is a structural disincentive to rigorously enforce animal welfare laws, especially against large-scale agricultural operations. This combination of chronic underfunding and regulatory capture significantly hampers the effective enforcement of animal protection laws, highlighting the systemic challenges faced by veterinary authorities in Germany.

A ruling by the Regional Court of Magdeburg (LG Magdeburg)Footnote ⁵⁶ underscores these enforcement deficits. The court acknowledged that the defendants—animal rights activists who broke into livestock facilities—had prior knowledge that reports of violations submitted without video or photographic evidence were historically disregarded by both prosecutors and veterinary authorities. The court found that the responsible authorities were neither willing nor able to take the necessary regulatory measures to enforce the Animal Welfare Livestock Ordinance (TierSchNutztV).Footnote ⁵⁷

This case illustrates how insufficient staffing and financial resources within licensing and oversight authorities exacerbate enforcement deficits. Despite their statutory obligations, enforcement agencies frequently lack the capacity to ensure effective implementation of the law, underscoring systemic weaknesses in Germany’s animal welfare oversight framework.

2.2. Monitoring and Inspections

The deficiencies in enforcement are also reflected in monitoring practices. Section 16(1) TierSchG stipulates that certain operations and facilities are subject to routine inspections. However, other areas—such as private pet ownership—are only inspected in response to specific complaints or suspicions of non-compliance. The current oversight system is inadequate, particularly regarding the continuous monitoring of previously approved facilities.Footnote ⁵⁸ In Bavaria, for example, animal facilities can expect to be inspected on average only once every forty-seven years,Footnote ⁵⁹ despite a steadily increasing rate of violations. In 2020, the proportion of inspected farms found to be in breach of legal requirements reached a record high of 33.2%,Footnote ⁶⁰ highlighting a significant discrepancy between the statutory obligations under animal protection law and their practical enforcement.

An audit team dispatched by the European Commission conducted a review of animal welfare controls in Germany in October 2019 and identified serious structural deficiencies in its final report.Footnote ⁶¹ The auditors found that the competent authorities lacked a coherent strategy for identifying and reducing severe animal welfare violations.Footnote ⁶² Among the key shortcomings were the absence of measurable animal welfare indicators, concrete performance targets, systematic prioritization, and effective allocation of resources.Footnote ⁶³ As a result, the report concluded that the existing animal welfare rules were not being effectively enforced in practice.Footnote ⁶⁴ A second audit conducted by the European Commission in 2019, this time focusing on food safety controls in the beef production sector, confirmed these concerns. The auditors criticized insufficient inter-agency coordination, which undermined the effectiveness of official inspections. Moreover, enforcement measures in response to animal welfare violations were found to be, in some cases, disproportionate and lacking in deterrent effect. The audit also pointed to persistent structural problems in staffing levels and capacity within the competent authorities.Footnote ⁶⁵

Effective oversight requires more than sporadic inspections—it demands a consistent and proactive monitoring system. Regulatory compliance is significantly influenced by two key factors: the likelihood of detection, determined by the frequency of inspections, and the severity of sanctions imposed in response to violations. Both elements are essential to deterring non-compliance and ensuring meaningful enforcement of animal protection laws. Without a robust inspection regime, regulatory violations often go undetected or unpunished, further weakening the already fragile enforcement landscape.

2.3. Systemic Disincentives and Structural Challenges

Taken together, the evidence points to systemic disincentives shaping the actions of enforcement authorities. Conflicts of interest, economic pressures, and resource constraints create a recurring pattern in which animal welfare enforcement is deprioritized in favor of competing economic objectives.

3. Procedural Barriers in Animal Protection Law

The administrative enforcement deficit is further exacerbated by the judicial enforcement deficit. Authorities frequently uphold their actions with the knowledge that administrative judicial review is effectively unavailable. Germany’s legal framework for animal protection is hindered by significant procedural barriers that severely limit the enforcement of animal welfare laws. These barriers stem primarily from the rigid requirements of the Administrative Court Procedure Code (Verwaltungsgerichtsordnung, VwGO)Footnote ⁶⁶ , which restricts access to judicial review to individuals who can demonstrate a violation of their subjective rights under Section 42 (2) VwGO. While this principle ensures efficient case management and prevents frivolous lawsuits, it creates substantial challenges in the context of animal protection, as animals themselves do not possess legally enforceable rights, nor can advocacy organizations typically act on their behalf.

3.1. The Restriction of Legal Standing in Administrative Law (Schutznormtheorie)

The fundamental right to judicial protection is anchored in Article 19(4) of the German Basic Law, which guarantees that any person whose rights have been violated by public authority has access to legal recourse. This principle is codified in administrative law under Sections 42(2), 113 (1) sentence 1, and 113 (5) VwGO. Section 42(2) VwGO stipulates that administrative legal recourse is only available if the claimant alleges that their rights have been violated by the administrative action in question. This requirement is designed to exclude popular actions and interest-based litigation, thereby preventing administrative courts from being overburdened with cases brought by parties without a direct legal interest.Footnote ⁶⁷ Section 113 (1) sentence 1 and Section 113 (5) VwGO serve as corresponding provisions at the substantive review stage. While, at the admissibility stage under Section 42(2) VwGO, the mere possibility of a violation of a subjective right is sufficient, Section 113 (1) sentence 1 and Section 113 (5) VwGO require the actual violation of a subjective right to be established.

The determination of the subjective right required under Section 42(2) VwGO is primarily guided by the protective norm theory (Schutznormtheorie Footnote ⁶⁸ ),Footnote ⁶⁹ a cornerstone of German administrative jurisprudence. According to this theory, a legal norm grants individual rights only if it is intended not merely to serve the public interest but also to protect a specific legal position of an individual. The key question is whether the norm in question solely serves the general public interest or also creates an enforceable legal entitlement.Footnote ⁷⁰ This determination is based on the objective content of the provision rather than the intent of the historical legislator.Footnote ⁷¹

It is often difficult to ascertain whether a subjective public right exists or is merely a legal reflex; for this reason, inter alia, the possibility theory (Möglichkeitstheorie) provides that a claim is admissible if there is at least a possibility that a subjective public right has been violated.Footnote ⁷² A claim is only inadmissible if it is obvious and unequivocal that the rights asserted by the claimant cannot exist under any interpretation of the law.Footnote ⁷³

3.2. The Absence of Third-Party Protection in Animal Protection Law

Under the prevailing legal interpretation, the provisions of the German Animal Protection Act do not confer third-party protection within the meaning of the protective norm theory.Footnote ⁷⁴ Instead, they are regarded as objective legal norms that serve the public interest rather than creating enforceable individual rights.Footnote ⁷⁵ Consequently, individuals advocating for the enforcement of animal protection laws face significant procedural barriers under Section 42(2) VwGO, as they cannot assert a violation of their own rights. This excludes the possibility of bringing claims on behalf of animals before German administrative courts.

This legal framework creates a fundamental paradox: individuals adversely affected by stringent animal protection measures, such as farmers or industries subject to regulatory restrictions, have standing to challenge these measures in court. In contrast, insufficient enforcement of animal protection standards cannot be contested, as animals lack legal standing and no subjective public rights exist that would enable advocacy organizations to seek judicial review. This asymmetry significantly weakens the enforcement of animal welfare laws, as courts are accessible to those seeking to limit regulatory protections, but not to those advocating for stronger enforcement. As a result, the ethical principles enshrined in Article 20a GG and the TierSchG often fail to translate into meaningful judicial oversight, further widening the gap between legal commitments and practical outcomes.

III. The Legal Status of Animals in Civil Law

In addition to the public law provisions of the German Animal Protection Act, Section 90a of the German Civil Code (Bürgerliches Gesetzbuch, BGB) contains a seemingly significant provision regarding the legal status of animals.Footnote ⁷⁶ Since 20 August 1990, Section 90a BGB has formally removed animals from the category of objects (Sachen), reflecting the legislative intent to acknowledge that “animals are fellow creatures of humans and sentient beings capable of suffering, to whom humans owe protection and care.”Footnote ⁷⁷ This principle found expression in civil law through the explicit declaration in Section 90a sentence 1 BGB that animals are no longer classified as things. However, Section 90a sentence 3 BGB simultaneously mandates that legal provisions applicable to things also apply to animals, unless otherwise stipulated by law. As a result, Section 90a BGB is widely regarded as having primarily symbolic rather than substantive legal significance, as it has not led to a fundamental transformation of the legal status of animals in civil law.Footnote ⁷⁸ Instead, animals continue to be treated as “things sui generis,”Footnote ⁷⁹ that is, as a special category of things that are formally distinguished from inanimate objects, yet remain largely subject to the general provisions of property law. The relevant statutory provision does not confer independent legal rights or create enforceable entitlements for animals. In practice, animals are, for the most part, governed by legal regimes such as tort, contract, and family law as if they were ordinary property.

IV. Structural Enforcement Deficit in Animal Law

The analysis demonstrates that the core weakness in animal protection law lies in its enforcement mechanisms. This is not a matter of coincidence or isolated failures; rather, the enforcement deficit is systemic. Germany’s individual rights-based system of legal protection reaches its limits when applied to animal welfare, as procedural filters such as standing requirements are inherently ill-suited to this field. Although administrative authorities are bound by law, an objective violation of the law frequently remains unsanctioned under the current system of subjective legal protection. The absence of adequate legal oversight mechanisms results in a loss of regulatory control for the legislature, ultimately undermining democratic governance.Footnote ⁸⁰ This raises a fundamental question: What interest does a democratic constitutional state have in maintaining a legal norm that is routinely disregarded, merely because no individual possesses standing to challenge its violation?Footnote ⁸¹ Nevertheless, these provisions retain expressive value: they articulate societal commitments and ethical aspirations, even if judicial mechanisms for enforcement are lacking. As such, the symbolic function of animal protection norms should not be dismissed—but symbolic status alone cannot substitute for legal accountability. This lack of enforceability undermines the rule of law and erodes public trust in the legal system’s capacity to guarantee compliance and accountability. The following proposals seek to bridge this enforcement gap.

I. Representative Action by Associations

Reform considerations aimed at enhancing compliance with animal welfare law often focus on strengthening procedural mechanisms.Footnote ⁸² One such proposal involves expanding representative action rights (Tierschutzverbandsklage) for animal protection organizations—an instrument that is more firmly established in other jurisdictions, such as Norway and the Netherlands.Footnote ⁸³ A comparable mechanism exists in the United States in the form of the citizen suit, which enables private individuals to bring legal action to enforce statutory provisions—particularly in the field of environmental law.Footnote ⁸⁴

Representative action enables recognized animal protection organizations to participate in specific proceedings as advocates for animals and to challenge administrative inaction. Since the constitutional recognition of animal protection in Article 20a of the German Basic Law in 2002, the introduction of representative action has been a central issue in the animal welfare debate.Footnote ⁸⁵ Yet, at the federal level, no legal framework exists for animal protection organizations to bring such claims. Although several legislative initiatives have sought to introduce Tierschutzverbandsklage, all have ultimately failed.Footnote ⁸⁶ Nonetheless, eight federal states (Länder) have implemented some form of representative action for animal protection organizations.Footnote ⁸⁷

The reluctance to embrace representative action in animal protection law is not an isolated phenomenon but reflects a broader structural pattern within German administrative law. Representative action occupies an exceptional—and historically contested—position in this legal context. It is frequently described as an “anomaly,”Footnote ⁸⁸ primarily because the prevailing standing doctrine, the Schutznormtheorie, limits access to the courts to individuals who claim a direct violation of their subjective rights. Despite this doctrinal constraint, representative action has gained a foothold in environmental law—not as a result of domestic legal innovation, but largely in response to external legal obligations imposed by the European Union.Footnote ⁸⁹ More broadly, however, the concept continues to face systemic resistance within German legal culture. This persistent aversion is increasingly difficult to defend—both in light of pressing environmental and animal protection challenges and in view of Germany’s supranational commitments.Footnote ⁹⁰

1. The Preventive and Regulatory Effects of Representative Action

If representative action (Verbandsklage) were established at the federal level, recognized organizations would be granted the right to participate in administrative proceedings before an administrative act is issued. This includes the right to submit statements, access information, and initiate legal action. Even the mere availability of representative action has a deterrent effect on both administrative authorities and regulated entities. The prospect of legal challenge incentivizes authorities to conduct more thorough assessments before issuing decisions, fostering greater compliance and reducing unlawful administrative practices. Beyond its deterrent function, representative action also promotes early-stage negotiations, encouraging compromise solutions before disputes escalate to formal legal proceedings.Footnote ⁹¹ Thus, while its full impact is difficult to quantify empirically, it serves as an indirect but powerful mechanism of legal oversight, reinforcing regulatory compliance beyond individual cases.

2. The Procedural Role of Representative Action in Administrative Law

From a procedural perspective, representative action integrates into administrative law as follows: Under Section 42(2) of the Administrative Court Procedure Code (Verwaltungsgerichtsordnung, VwGO), a lawsuit is only admissible if the claimant asserts that they have been harmed in their rights by an administrative act or its rejection or omission, unless otherwise provided by law. Representative action serves as such a statutory exception, addressing gaps in individual legal protection.

Unlike individual claimants, associations acting as representative litigants do not assert their own subjective rights. Instead, they are authorized to challenge violations of legal provisions enacted in the public interest. In this way, representative action shifts the focus from individual legal standing to the enforcement of public interest norms, strengthening regulatory compliance and ensuring greater accountability in administrative decision-making. By allowing organizations to bring claims that address systemic violations, representative action expands judicial review, ensuring that widespread violations do not evade legal scrutiny.

Moreover, granting legal standing to advocacy organizations would enable civil society to act as a watchdog for animal welfare, reinforcing compliance with existing laws and creating a more effective enforcement mechanism. Such reforms could also enhance public trust in the legal system’s commitment to ethical governance and the rule of law.

3. Integrating Animal Protection into Environmental Law

The procedural deficits in animal welfare law prompt the question of whether—and to what extent—access to the courts could benefit from procedural models established in environmental law. In contrast to animal protection, representative actions are firmly established in environmental law. The Environmental Appeals Act (Umwelt-Rechtsbehelfsgesetz, UmwRG)Footnote ⁹² grants recognized environmental organizations the right to participate in administrative and judicial proceedings. This allows them to challenge environmentally significant decisions, particularly where violations of environmental law have occurred, without the need to demonstrate an individualized legal interest.

The legal framework was heavily influenced by European Union and international law. The foundation was laid at the Rio Summit in 1992,Footnote ⁹³ and binding obligations were established through the Aarhus Convention. On June 25, 1998, the Aarhus ConventionFootnote ⁹⁴ codified international minimum standards in environmental law, ensuring public participation in environmental decision-making and access to justice in environmental matters.

3.1. Animal Protection in Environmental Law

Although certain provisions of environmental law may, in some instances, be relevant to animal protection, their applicability remains limited in scope. Procedural access to courts under the Environmental Appeals Act is available for environmental licensing decisions pursuant to Section 1(1) sentence 1 numbers 1 and 2 UmwRG. These provisions enable recognized environmental organizations to seek full judicial review of such decisions. In this context, animal welfare concerns may be raised as part of the review process.

However, a claim under Section 1(1) sentence 1 number 1 UmwRG requires that the project be subject to an environmental impact assessment (EIA). Under current law, EIA obligations only apply to large-scale animal farming operations, such as facilities with at least 60,000 laying hens, 85,000 broilers, 3,000 pigs, or 9,000 piglets.Footnote ⁹⁵ Similarly, claims under Section 1(1) sentence 1 number 2 UmwRG require that the facility be subject to licensing under the Federal Immission Control Act (Bundes-Immissionsschutzgesetz). This threshold, too, applies only to large-scale operations—e.g., more than 40,000 hens or broilers, 2,000 pigs, or 6,000 piglets.Footnote ⁹⁶

In practice, however, most animal farming operations in Germany fall well below these thresholds. The average cattle farm keeps around 108 animals, and the average pig farm 810 animals.Footnote ⁹⁷ Only approximately 8.9% of pig farms exceed the 2,000-animal threshold.Footnote ⁹⁸ As a result, environmental standing rights under the UmwRG are generally available only in cases involving large industrial-scale livestock facilities. Moreover, these claims are generally limited to new permitting procedures; challenges to permit modifications are admissible only when the modification reaches a certain threshold of intensity.

Section 1(1) sentence 1 numbers 5 and 6 UmwRG also allow for legal challenges to projects that are neither subject to an EIA nor governed by immission control law. However, such actions may only invoke violations of environmental law provisions.

According to Section 1(4) UmwRG, environmental law provisions are defined by reference to the Environmental Information Act (Umweltinformationsgesetz, UIG). According to the Federal Administrative Court (Bundesverwaltungsgericht, BVerwG), animal protection does not fall within this definition.Footnote ⁹⁹ This position, however, was not shared by the lower court in the same caseFootnote ¹⁰⁰ , nor is it consistent with the case law of the Aarhus Convention Compliance Committee (ACCC), which has adopted a more expansive view of environmental protection.Footnote ¹⁰¹

3.2. Integration Potential and Normative Tensions

The sharp divide between environmental and animal welfare law fails to reflect the ecological interdependence between both fields and gives rise to significant regulatory blind spots. While environmental law is primarily concerned with the protection of ecosystems and the conservation of biodiversity, animal law centers on the welfare of individual animals. This distinction is mirrored in legislation: the Federal Nature Conservation Act (Bundesnaturschutzgesetz)Footnote ¹⁰² focuses on the protection of wild species and their habitats, whereas animal protection law governs the treatment of animals in agriculture, research, breeding, and domestic settings.

These two domains can, at times, be in direct normative conflict. In Germany, for instance, the management of so-called invasive species such as the raccoon (Procyon lotor) illustrates the normative tension between environmental and animal protection perspectives. Environmental authorities view raccoons as a threat to native biodiversity and support population control through widespread culling.Footnote ¹⁰³ Animal protection organizations, by contrast, question both the ecological basis and ethical legitimacy of such measures, arguing that the environmental impact is often overstated and advocating for non-lethal alternatives such as relocation or deterrence.

Nonetheless, environmental and animal protection law, despite their distinct regulatory focuses, often pursue converging objectives. The lack of integration between environmental and animal protection law becomes particularly evident in the context of industrial livestock farming. Although livestock production contributes significantly to environmental harms such as climate change, deforestation, and water pollution, animal law issues are largely excluded from environmental review procedures. While environmental organizations are entitled to bring legal action under Section 3 of the Environmental Appeals Act (Umweltrechtsbehelfsgesetz), animal protection organizations remain procedurally sidelined—even when their concerns overlap with core environmental objectives. This exclusion not only weakens overall regulatory effectiveness but also results in an unjustified differential treatment of the two groups, contravening the principle of equal treatment.

Recognizing the mutual dependencies between animal welfare and environmental protection is essential for a coherent legal framework. Environmental measures often have incidental benefits for animal welfare—for example, regulations on wind energy projects may protect bats, and shark finning bans serve both conservation and anti-cruelty goals. Conversely, protecting individual animals can promote environmental aims, as illustrated by Section 45(5) of the Federal Nature Conservation Act, which supports the rehabilitation of injured wildlife to stabilize protected populations.Footnote ¹⁰⁴ Bridging the divide between these two legal regimes is therefore not only conceptually coherent, but also ecologically necessary.

4. Toward a Harmonized EU Animal Protection Law

Beyond national reform, a harmonized approach at the EU level would be desirable. Even within the European Union’s legal framework, enforcement deficits persist,Footnote ¹⁰⁵ undermining the effective implementation of animal welfare standards.

A corresponding legislative measure on EU animal protection law must be grounded in sector-specific competence norms, as the Member States retain primary responsibility for implementing Union law under Article 291(1) TFEU (Treaty on the Functioning of the European Union). The principle of procedural autonomy grants Member States discretion in enforcing EU law; however this autonomy is limited by the right to effective judicial protection under Article 47 of the Charter of Fundamental Rights of the European Union (GRC), as well as by the principles of equivalence and effectiveness.Footnote ¹⁰⁶ The EU does not possess a general legislative competence to regulate the administrative and procedural laws of the Member States. Similarly, the EU lacks an original legislative competence for animal protection, as Article 13 TFEU does not create an independent legal basis for animal welfare regulations.

Instead, any EU-level animal protection measures must be based on sectoral competence norms.Footnote ¹⁰⁷ Representative action for farmed animals could be grounded in Article 43(2) TFEU, which governs the common agricultural policy. Legal standing for cases concerning wild animals could derive from Article 192 TFEU, which addresses environmental policy.Footnote ¹⁰⁸ The substantive legal competence for animal welfare regulations also extends to the procedural mechanisms necessary for their enforcement, including representative action (Verbandsklage). A precedent for such an approach exists in environmental law, where Directive 2003/35/ECFootnote ¹⁰⁹ was adopted based on Article 192 TFEU—the EU’s environmental competence provision. Under this framework, access to judicial review was conceptualized as a procedural annex to substantive environmental law. Following this model, representative action in animal welfare law could be implemented through a directive as part of secondary legislation, enhancing the enforceability of animal welfare standards across the EU.

Beyond national reforms, the global nature of animal welfare issues demands multilateral solutions. The deterrent effect of regulatory loopholes and concerns about economic migration underscore the urgency of harmonizing international standards.Footnote ¹¹⁰ The Aarhus Convention, for example, has proven highly effective in the field of environmental lawFootnote ¹¹¹ —an approach that could be replicated in animal protection law. At the same time, while international consensus-building remains a time-intensive process,Footnote ¹¹² unilateral actions continue to play a crucial role in demonstrating ethical leadership and creating momentum for global change.

II. Broader Interpretation of Subjective Rights

Instead of implementing a representative action system for animal protection, an alternative approach could be the recognition of procuratorial rights. Rather than foregoing subjective rights in individual cases, animal protection organizations would be granted their own subjective public rights. By applying the protective norm theory (Schutznormtheorie) flexibly, Section 42(2), second clause, of the Administrative Court Procedure Code (VwGO) could be interpreted to allow animal protection organizations to assert a right in cases where animal welfare regulations have been violated, provided such action aligns with their statutory purpose.

A comparative example can be found in Austria, where environmental organizations are granted subjective rights in environmental cases, rather than foregoing subjective rights as is the case in Germany.Footnote ¹¹³ While legislative action is typically required to introduce representative action mechanisms, procuratorial rights could also be recognized through judicial interpretation, providing a more immediate and adaptable avenue for strengthening animal protection enforcement.Footnote ¹¹⁴ The Protective Norm Theory (Schutznormtheorie) provides sufficient flexibility to support a broader interpretation of subjective rights, while potentially reducing certain elements of legal certainty.

III. Competitor Lawsuits as a Mechanism for Enforcing Animal Welfare Law

Given the economic dynamics of market competition, competitor lawsuits could serve as an effective mechanism for enforcing compliance with animal welfare law. Allowing law-abiding businesses to challenge violations of the Animal Protection Act would help ensure that compliance with legal standards does not place them at a competitive disadvantage. In this way, economic competition could be leveraged to reinforce adherence to animal welfare regulations, preventing market distortions caused by unlawful practices. Expanding competitor lawsuits to the field of animal welfare law would enable companies that gain an unfair advantage through non-compliance to be held accountable by their competitors. This approach would not only help prevent distortions in competition but also incentivize businesses to comply with animal protection regulations, thereby aligning market behavior with legal and ethical obligations.Footnote ¹¹⁵

The animal welfare provisions related to product manufacturing do not appear to fall within the scope of market conduct regulations (Marktverhaltensregelungen) as defined in Section 3a of the German Act Against Unfair Competition (Gesetz gegen den unlauteren Wettbewerb, UWG). Animal welfare regulations are primarily aimed at protecting animal welfare, rather than establishing uniform competitive conditions for businesses. Their function is not secondarily intended to regulate competition within a given market. According to the Higher Regional Court of Hamburg (Oberlandesgericht Hamburg) competition courts should not assume the role of a supervisory authority tasked with enforcing public law provisions.Footnote ¹¹⁶ Nonetheless, the introduction of competitor lawsuits in animal welfare law remains a viable consideration, akin to the proposal included in the Commission’s draft of the Environmental Code (Umweltgesetzbuch).Footnote ¹¹⁷

IV. Legal Personhood for Animals

An internationally significant legal development concerns the recognition of animals as independent legal entities.Footnote ¹¹⁸ Across various jurisdictions, legal frameworks are evolving to acknowledge the legal personhood of nonhuman beings. This section outlines recent developments in the legal status of animals and the rights of nature and calls for a more integrated approach that connects both paradigms. While a comprehensive examination lies beyond the scope of this Article, the following aims to outline the key dimensions of the debate.

1. Animal Rights

The concept of legal personhood for animals has been debated in legal scholarship for decades.Footnote ¹¹⁹ More recently, courts in several jurisdictions have begun to recognize animals as legal subjects. Notable examples include the Cecilia case in ArgentinaFootnote ¹²⁰ and the Estrellita case in Ecuador,Footnote ¹²¹ where courts acknowledged the legal status of a chimpanzee and a woolly monkey, respectively. In Finland, a citizens’ initiative proposing the inclusion of basic animal rights in the Finnish Constitution has been submitted to Parliament.Footnote ¹²² The Nonhuman Rights Project in the United States has sought to establish animal personhood through habeas corpus petitions, arguing that highly sentient animals should be recognized as rights-holders under common law.Footnote ¹²³ In 2023, the City of Ojai in the United States adopted an ordinance recognizing elephants as rights-holders.Footnote ¹²⁴

The normative foundation of animal rights is primarily rooted in sentience-based reasoning. This pathocentric approach, from the Greek pathos, meaning “suffering,” assigns intrinsic moral value to all sentient life and emphasizes the individual interest of animals in their own well-being.Footnote ¹²⁵ In contrast to the rights of nature approach, which often presumes that all entities—animate or inanimate—may qualify as rights-holders, anything goes,Footnote ¹²⁶ the animal rights approach generally focuses on sentient beings. While a gust of wind could theoretically be granted rights under a broad nature rights framework, legal personhood for animals is typically limited to beings capable of suffering.

2. Rights of Nature

The rights of nature movement has gained significant momentum. Ecuador became the first country to enshrine rights for nature in its Constitution in 2008—Articles 10(2) and 71—recognizing nature (Pacha Mama) as a subject of rights and granting individuals and communities the ability to enforce these rights.Footnote ¹²⁷ In 2022, Spain adopted legislation recognizing the Mar Menor Lagoon as a legal entity.Footnote ¹²⁸ The lagoon was granted rights to exist, be preserved, and, where necessary, be restored. Legal personhood for nature has likewise been recognized in New Zealand, where the Te Urewera forest, in 2014, the Whanganui River, in 2017, and Mount Taranaki, in 2025, were granted legal status through parliamentary acts.Footnote ¹²⁹

In a landmark decision on January 27, 2022, Ecuador’s Constitutional Court applied rights of nature provisions to an individual woolly monkey, marking a pivotal moment in the legal recognition of animals as rights-holders.Footnote ¹³⁰ However, within the framework of the rights of nature, animals are generally not granted distinct or elevated rights beyond those afforded to other natural entities. Rather, all components of the Earth system—whether animals, rivers, forests, or mountains—are understood to possess the same fundamental rights by virtue of their ecological interconnectedness.

Despite their partially shared aspirations,Footnote ¹³¹ animal rights and rights of nature are often treated as separate discourses. The divergence is also reflected in public perception: while both frameworks remain outside the legal mainstream, the rights of nature tend to be viewed with greater openness or acceptance, whereas animal rights are still often perceived as more radical or contentiousFootnote ¹³² —even though the case for recognizing rights to sentient beings such as cows may be ethically more urgent than that of rivers or forests.Footnote ¹³³ In fact, rights of nature often go further and are more philosophically radical, yet they are met with greater acceptance. This raises the question: Why is the animal rights approach perceived as more provocative than the rights of nature framework? As Peters argues, the reluctance to extend rights to animals reveals an implicit anthropocentrism at the heart of the rights of nature discourse. Legislators, courts, and democratic societies may be more willing to grant rights to nature because such recognition remains largely symbolic and does not challenge our deeply embedded patterns of consumption.Footnote ¹³⁴

Despite their differences, animal rights and rights of nature share core normative commitments. Both challenge anthropocentric legal assumptions, reject the commodification of nonhuman life, affirm its intrinsic value, and call for a fundamental rethinking of the human-nature relationship. Though historically treated as distinct or even incompatible, animal and environmental law can benefit from mutual integration.Footnote ¹³⁵

3. Legal Developments in Germany

The recognition of legal personhood for nature has also gained traction in Germany, as illustrated by the judgment of the Regional Court of Erfurt (Landgericht Erfurt) on August 2, 2024.Footnote ¹³⁶ In a historic first for Germany, the court recognized the rights of nature based on Article 51(1) of the Charter of Fundamental Rights of the European Union, particularly in conjunction with Articles 2 and 3(1) and in connection with Article 37. The court held that these fundamental rights inherently apply to nature and specific ecosystems, conceptualizing them as “ecological persons.”

According to the court, the Charter of Fundamental Rights establishes a comprehensive framework ensuring that the existence, preservation, and regeneration of ecological entities are legally protected.Footnote ¹³⁷ The ruling also emphasized that Article 53 of the Charter mandates comparative legal perspectives in its interpretation. Given that jurisdictions across the Global South, as well as the United States and New Zealand, have already recognized rights of nature, the European legal order cannot remain insulated from these international trends.Footnote ¹³⁸ Against this backdrop, granting legal recognition to nature in European jurisprudence appears legally and doctrinally justified. European courts could follow the approach taken by Colombian and Peruvian jurisprudence, where rights of nature have been judicially recognized through holistic interpretations of their respective legal systems, even in the absence of explicit legislative provisions.Footnote ¹³⁹ The decision has also drawn criticism, however, for potentially overstepping the limits of judicial law-making in an area some argue should be left to democratic legislatures.Footnote ¹⁴⁰

This decision, however, should not obscure the fact that in Germany, the topic remains largely marginal. As reflected in Article 20a of the Basic Law, the German legal system adheres to an anthropocentric approach, treating nature and animals as objects of protection rather than a subject of rights. Nevertheless, recognizing animals as legal persons aligns with the German constitutional framework and represents a coherent extension of existing normative commitments.Footnote ¹⁴¹

V. Institutional Reform: Strengthening Enforcement Capacities

In addition to the legal instruments discussed above, targeted institutional reforms could also contribute to addressing the enforcement deficit. Additional measures could focus on bolstering institutional capacities by increasing personnel and material resources,Footnote ¹⁴² appointing an animal protection attorney for criminal cases,Footnote ¹⁴³ redefining the role of the animal welfare commissionerFootnote ¹⁴⁴ and the animal welfare commission,Footnote ¹⁴⁵ or establishing an animal welfare ombudsperson.Footnote ¹⁴⁶ Within the judiciary, specialized public prosecutors for animal welfare offenses could improve legal oversight and enforcement in the field of criminal law.

A realignment of ministerial responsibility for animal welfare could also serve as a meaningful structural reform. Currently, the Federal Ministry of Food and Agriculture (Bundesministerium für Ernährung und Landwirtschaft, BMEL) holds jurisdiction over this area—a setup that inherently creates conflicts of interest, as the ministry’s core mandate includes promoting agricultural interests. A more suitable alternative could be the Ministry of Justice, particularly should rights be recognized, or the Ministry of the Interior, if animal protection is conceptualized as a matter of public order.

While these institutional adjustments could provide valuable complementary measures, they cannot replace the fundamental reforms required, particularly in procedural animal protection law.

VI. Conclusion

This analysis presents four distinct avenues to address the enforcement deficit in animal protection law: representative action (Verbandsklage), procuratorial rights, competitor lawsuits, and legal personhood for animals. Each of these mechanisms has strengths and limitations, requiring careful consideration of their feasibility, effectiveness, and long-term implications.

A key criterion in evaluating these options is their ability to remedy administrative enforcement failures. From a pragmatic perspective, representative action offers the most immediately viable path forward. It could help overcome judicial access barriers without requiring structural changes to Germany’s individual rights-based legal system. While representative action has its limits—potentially falling short of fully addressing systemic deficiencies—it remains a politically realistic and incremental step toward stronger enforcement.

The most far-reaching proposal—recognizing animals as legal persons—presents an undeniable normative appeal but remains politically contentious. Over time, representative action and procuratorial rights could serve as stepping stones toward broader legal recognition, bridging the gap between symbolic commitments and substantive enforcement mechanisms.

Unlike environmental law, which has seen significant legal advancements, animal protection law has remained largely stagnant from a procedural law perspective. This stagnation underscores the critical role of public interest litigation in driving legal change. With this in mind, the following section explores the role of public interest litigation in advancing animal law.

I. Animal Rights Litigation in Germany

In recent years, particularly over the past decade, strategic litigation in animal rights law has gained momentum, with the majority of cases concentrated in the Americas. Notable examples include the Cecilia case in ArgentinaFootnote ¹⁴⁸ and the Estrellita case in Ecuador,Footnote ¹⁴⁹ where courts acknowledged animals as legal persons. In contrast, Germany has seen only limited strategic litigation in this field. To date, only two cases appear to have been pursued with a strategic approach:Footnote ¹⁵⁰ the Seals Lawsuit of 1988, and the Piglets’ Constitutional Complaint of 2021, both of which illustrate key procedural challenges in advancing animal law through litigation. These cases will be examined in the following discussion.

1. The Seals Lawsuit

The so-called Seals Lawsuit (Robbenklage) represents one of the earliest nationally significant cases in Germany that could be classified as strategic litigation. The plaintiffs sought to advance judicial development in both environmental and animal protection law, introducing the concept of legal personhood for animals into German legal discourse.

In August 1988, on the initiative of the Institute for Environmental Law, nine of Germany’s most prominent environmental organizations—including BUND, Greenpeace, Robin Wood, and the WWF Environmental Foundation—filed an application under § 80(5) VwGO “on behalf of” the seals. The application challenged the permits issued by the German Hydrographic Institute (DHI) for the dumping of dilute acid into the North Sea. The case was brought before the Administrative Court of Hamburg, seeking to restore the suspensive effect of the objections filed against the permits. The respondent was the Federal Republic of Germany, represented by the DHI.

1.1. Legal and Environmental Background

The lawsuit must be understood within the broader environmental and legal landscape of its time. In the late 1980s, there was significant public interest in environmental issues, fueled by growing protests against environmental policies and the early recognition of climate-related problems. By May 1988, approximately 80% of the seal populations in the North Sea were reported extinct. It was speculated that this decline was linked to the dumping of dilute acid and waste incineration in the North Sea. While such practices were generally prohibited under German law, they were permissible under certain conditions with a special permit, as stipulated in Section 2(2) of the High Seas Dumping Act (Hohe-See-Einbringungsgesetz, HSEG).Footnote ¹⁵¹ The provision allowed the disposal of substances at sea only if they posed no harm to marine ecosystems, including living stocks and marine flora and fauna. If the competent authority determined that these conditions were met, it retained discretion to issue a permit.

Under the prevailing interpretation of the protective norm theory (Schutznormtheorie), third parties lacked standing to challenge such permits, as Section 2(2) HSEG did not confer subjective rights. Aware of this issue, the environmental organizations sought interim relief from the Administrative Court of Hamburg. Notably, the application listed not only the environmental organizations as claimants but also the seals themselves.

1.2. Legal Arguments

The applicants based their argument for the seals’ participation capacity on Section 61 VwGO, which governs standing in administrative proceedings. While they also addressed deficiencies in the protective norm theory, their primary argument was that legal capacity should not be exclusively tied to human status. Citing historical precedents and the recognition of legal persons, they asserted that legal capacity is not an inherent attribute of human beings but a construct that could—and should—be extended to non-human entities.

A central pillar of their case rested on the principle of judicial development of the law (richterliche Rechtsfortbildung). The applicants argued that courts have, in numerous instances, addressed apparent legal gaps through judicial rulings. As examples, they pointed to decisions of the Federal Court of Justice (Bundesgerichtshof, BGH) that recognized general personality rights and awarded compensation for non-material damages absent explicit statutory provisions. Similarly, the Federal Constitutional Court (Bundesverfassungsgericht, BVerfG) had, in certain cases, permitted interim relief despite statutory provisions suggesting otherwise, interpreting procedural rules contra legem.

The applicants contended that Section 2(2) HSEG was designed to protect “something”—namely, marine life. However, its effectiveness was compromised if those it was meant to protect lacked the ability to invoke its protections, particularly in situations of clear and imminent harm. They asserted that this constituted a legislative gap, which the court had the authority to address.

1.3. Judicial Reasoning and Ruling

On September 22, 1988, the Administrative Court of Hamburg rejected the application.Footnote ¹⁵² The court held that the seals lacked legal standing under Section 61 VwGO, which limits participation capacity in administrative proceedings to legal persons and natural persons. The court reasoned that German law interprets the term “natural persons” to exclusively refer to humans. The court further found that Section 1 of the German Animal Protection Act (Tierschutzgesetz, TierSchG) framed the protection of animals as a moral duty of humans rather than as a right of animals themselves. It cited additional provisions demonstrating the legislature’s clear rejection of granting independent rights to animals. Procedurally, the court found the application to be impermissibly vague. It noted that the claim failed to specify which species of seals (Phoca vitulina, Phoca hispida, Halichoerus cristata, or others) were purportedly exercising the claimed rights, as well as their respective populations and geographical distributions.

Contrary to the applicants’ arguments, the Administrative Court saw no scope for judicial development of the law (richterliche Rechtsfortbildung) in this case, as it determined that there was no legislative gap. Section 61 VwGO, which ties participation capacity to legal capacity and limits it to persons, was considered conclusive. The court reasoned that the legislature could not have intended to delegate such a fundamental question to judicial lawmaking. To underscore this position, the court referenced the Roman legal tradition, which assigned rights exclusively to persons. The court did not assess whether a supplementary legal rule was necessary, as it had already concluded that no legislative gap existed. The definition of “persons” in Section 61 VwGO was explicit, and the legislature had deliberately chosen to restrict participation capacity to humans and legal persons, concluding that any changes in this regard fell within the purview of the legislature, not the judiciary.

1.4. Legal and Political Impact

The case exemplified the structural barriers preventing effective judicial oversight in animal and environmental law. Yet, despite the legal defeat, the Seals Lawsuit had a substantial political impact. The extensive media coverage generated by the litigation contributed to significant policy changes: the dumping of dilute acid and waste incineration at sea were subsequently banned without exception. Under the current Section 4 HSEG, only dredged material and urns may now be disposed of at sea.

While the court dismissed the argument for participation capacity, it acknowledged that the claim raised important policy questions—ones that could prompt a legislative response. Another notable outcome was that, although the permits in question were not revoked, they were not renewed after their expiration.

The case also played a crucial role in raising public awareness about enforcement deficiencies in environmental law. According to Blume, one of the lawsuit’s initiators, the litigation carried a symbolic dimension. The direct impact on the seals may have been minimal, as their decline resulted from a combination of environmental factors. However, the broader goal of the lawsuit was to introduce the idea of animal rights into public discourse and to inspire long-term change.Footnote ¹⁵³

2. The Piglets’ Constitutional Complaint

On November 19, 2020, the animal rights organization People for the Ethical Treatment of Animals (PETA) filed a constitutional complaint with the Federal Constitutional Court (Bundesverfassungsgericht, BVerfG).Footnote ¹⁵⁴ The filing attracted significant media attention and public discourse. A defining aspect of the complaint was that the primary claimants were listed as “male pigs kept in breeding and fattening operations within the Federal Republic of Germany that are surgically castrated without anesthesia or based on the Piglet Castration Competence Ordinance (Ferkelbetäubungssachkundeverordnung),” represented by PETA.

2.1. Legal Arguments

PETA’s legal argument rested on Article 93(1) number 4a of the German Basic Law (Grundgesetz, GG), which grants the right to file a constitutional complaint to “anyone” (jedermann) who claims a violation of their fundamental or equivalent constitutional rights. PETA contended that animals could qualify as legal persons, emphasizing that legal personhood is a construct of legal systems and has historically evolved to include entities beyond natural persons.

However, in early summer 2021, the Federal Constitutional Court issued a summary non-admission ruling (Nichtannahmebeschluss), declining to hear the complaint.Footnote ¹⁵⁵ As is common in such cases, the Court did not provide reasoning for its decision.Footnote ¹⁵⁶

2.2. Political Impact

At first glance, PETA’s approach might seem unlikely to succeed, and some critics dismissed the action as a publicity stunt. However, the filing attracted widespread attention, bringing the issue of piglet castration into the public spotlight. In this regard, the complaint—viewed through the lens of strategic litigation—can be considered successful. Even without judicial recognition, the litigation helped generate public debate on animal protection law. The attention generated by the case may have contributed to the legislature’s decision not to prolong the legal exemption permitting piglet castration without anesthesia. As of January 1, 2021, anesthesia is required for male piglets under eight days old.

II. Key Takeaways and Challenges

The Seals Lawsuit and the Piglets’ Constitutional Complaint illustrate both the potential and limitations of strategic litigation in animal protection law. A key takeaway from both cases is that strategic litigation can drive public awareness and influence policy, even in the absence of judicial success.Footnote ¹⁵⁷ The Seals Lawsuit, while legally unsuccessful, generated significant public and political pressure, ultimately contributing to the prohibition of acid dumping and waste incineration in the North Sea. Likewise, the Piglets’ Constitutional Complaint brought unprecedented media attention to the issue of piglet castration without anesthesia, potentially influencing the legislature’s decision not to extend the exemption for the practice.

However, both cases exposed the structural barriers within the German legal system, particularly the protective norm theory (Schutznormtheorie) and the restrictive interpretation of legal standing. These cases underscore the necessity of institutional changes to facilitate litigation in animal law. Without such reforms, courts will continue to face difficulties in providing meaningful oversight in cases concerning important interests such as animal welfare.
