Subject Matter Specialization of European Union Jurisdiction in the Preliminary Rulings Procedure

Abstract Over the years, judgments by the European Court of Justice (“ECJ”) have been—sometimes heavily—criticized. While the recent reforms to the EU’s judicial system have addressed the high caseload of the General Court of the European Union (“GC”), the perceived lack of quality of the ECJ’s judgments in preliminary rulings procedures remains an issue. This Article will outline in what way these judgments are criticized and try to examine the root causes of the criticism. It goes on to argue that subject matter specialization is an adequate answer to this criticism and examines how subject matter specialization can be introduced into the European Union (“EU”) judicial system.

serving on the GC eventually doubled as a result of three discrete increases. From September 1, 2019, onward, it is composed of two judges for each Member State. 3 The increase in the number of judges is meant to enable cases to be heard within a reasonable time as mandated by Article 47 of the Charter of Fundamental Rights of the European Union. 4 In Article 3 (2) of Regulation 2015/ 2422, the Council and Parliament tasked the ECJ with drawing up a report by December 26, 2017, on possible changes to the distribution of competence for preliminary rulings. In its report, the ECJ weighs the advantages and disadvantages of allocating to the GC some references for a preliminary ruling 5 and advocates against changing the distribution of jurisdiction over preliminary rulings. 6 This Article outlines a range of possible changes to the preliminary rulings procedure and advocates for reform while maintaining the current distribution of jurisdiction over preliminary rulings as suggested by the ECJ.
First, we deal with some criticisms of ECJ judgments in the preliminary rulings procedure and examine their root causes. Such criticism can hurt acceptance of the ECJ because the preliminary rulings procedure, which is a nexus between national and European law, represents a departure from the national legal orders. The judiciary can gain acceptance-so this Article claims-by introducing into the preliminary rulings procedure a specialization of EU jurisdiction by subject matter. Following this, in the second part of the Article we deal with various models of reform geared toward a specialized preliminary rulings procedure. We conclude with a number of minor proposals toward developing the jurisdiction of the EU.

B. Criticism of Judgments of the ECJ, Its Causes, and Effects
Overall, the ECJ has mastered with bravura its task of interpreting EU law such that it is applied evenly in all Member States. This is particularly so in light of numerous hurdles the judges in Luxemburg have to overcome. 7 Despite this astounding success story, the decisions of the ECJ are often criticized. As part of the study underlying this Article, we examined the judgments in Viking, 8 Laval, 9 and Alemo-Herron 10 as examples of the ECJ's criticized decisions in employment law which have come down through the preliminary rulings procedure. Surely, however, the points of criticism will be found to echo through reactions to ECJ decisions in other areas of law.
I. Criticism

Inconsistent Decisions and Flawed Systematization
The ECJ gets accused of deciding matters case by case and paying little attention to systematic development. The decisions-so the criticism goes-are sometimes contradictory, or at least not consistent with one another. 11 A few judgments are not even consistent internally, 12 while others do not allow an unambiguous rule to be discerned. 13 In the area of employment law, typical examples are decisions such as those pertaining to the Transfers of Undertakings Directive, 14 the Working Time Directive, 15 and the Posting of Workers Directive. 16 A major obstacle for anyone applying the law here is that the ECJ does not clarify when it departs from, or corrects, an earlier precedent. 17

Insufficient Setting Forth of Reasons and Deficient Portrayal of a System
Aside from the flawed development of any system, probably the greatest point of criticism is that the ECJ often just does not set forth sufficient reasoning in its decisions. 18 The more important a statement, the more detailed its underlying reasoning ought to be. Yet, in the ECJ's decisions oftentimes the reverse is true, 19   See generally Case C-438/05, supra note 8 (there is no sufficient statement of reason for the applicability of the fundamental freedoms to industrial actions. Furthermore, the validity of the so-called "theory of third-party effect of fundamental rights" depends on this reasoning); Case C-426/11, supra note 10 (the ECJ refers neither to the contractual freedom of employees nor explains the prevailing of the acquirer's rights); cf. EUR. PARL Sometimes the ECJ does not address the questions put to it although they touch central issues. 21 When it departs from the wording of a provision, the ECJ's reasoning is often quite brief. This makes it difficult to understand the consequences of the decision.
In its opinions, the ECJ commonly uses the technique of referencing its earlier decisions. But at the same time it only rarely provides reasons why the factual circumstances underlying the judgments are at all comparable to one another. 22 Without this reasoning, one can only conjecture about the basis for comparison. As a result, many judgments are not easy to grasp and are difficult to analyze critically.

Poor Understanding of Factual and Legal Circumstances
Some decisions create the impression that a better grasp of the factual, and even the legal circumstances might have led to better, more widely accepted judgments. In particular, there have been calls for better awareness of the national legal orders. 23 A certain superficiality is on display, for example, where a judgment does not precisely set forth the legal foundation. In one such case, Alemo-Herron, the ECJ did not clearly distinguish between rights under employment contracts versus under collective bargaining agreements. The judgments in Laval and Viking have occasioned the statement that the ECJ has a "poor understanding of the industrial relations background". 24 Here too, a more intensive analysis of the substance would presumably have led to a better result.

Insufficient Sensitivity to the Consequences
The desire for better understanding of the national legal regimes goes beyond the referring Member State and calls for greater sensitivity to the effect a judgment will have on legal systems throughout the Member States. When the ECJ, in making its determination, directs its attention only to the Member State where the referral originated, overly inclusive statements have the potential to endanger well-balanced systems of law, and to shift existing balances to the prejudice of one interest or another. 25

II. Effects of the Criticized Decisions 1. Diminished Acceptance and Lack of Legal Certainty
Judgments that barely set forth reasons, or do so incomprehensibly, do not really gain acceptance in the Member States and are therefore only reluctantly complied with. The inability to discern an unambiguous line in the decisions moreover leads to legal uncertainty. 26  address, the European fundamental rights as a signal that ECJ assumed the fundamental freedoms take precedence over the European fundamental rights. 27 Even if former ECJ President Vassilios Skouris has roundly rejected such an interpretation, 28 where judgments are short on reasoning, anyone applying the law remains uncertain what the law is.
Should the ECJ wish to make an even greater contribution to a European legal culture, it must comprehensibly set forth "all reasons for and against." 29 The brief presentation of reasons makes it burdensome to critically analyze the substance of decisions. Though that is precisely what must be possible when it comes to putting anyone in a position to advocate for acceptance of the ECJ's decisions. 30

Negative Impact on the Referral Practice of National Courts
The lack of legal certainty that follows from insufficiently reasoned opinions and poor awareness of the consequences of decisions affects the referral practice of national courts. 31 Although the practice incurs criticism, national courts sometimes do not refer matters for preliminary ruling in order to protect the national legal system from unpredictable consequences, complicating the ECJ's task of safeguarding the coherence of EU law. Conversely, national courts will also refer already settled issues, hoping the ECJ will reconsider its previous decisions. 32 Furthermore, lack of systematic development means the ECJ finds itself presented with legal questions that do not deviate essentially from questions decided in earlier cases, which unnecessarily increases its workload.

III. Causes of the Criticism and Specialization as a Possible Solution
What challenges do the judges on the ECJ face? What circumstances complicate adjudication at the ECJ? Can they be alleviated by specialization?

No Case Overload
Because the EU has expanded and its competences have grown, it seems reasonable to assume that the judges on the ECJ are burdened by an increasing number of cases, the sheer quantity of which is hard for them to handle. 33 Yet, it turns out that the risk of overload from the number of cases is small. Each expansion of the EU has been attended by new judgeships at the ECJ such that the number of personnel has grown in kind. Moreover, a careful look at the 2015 report on judicial activity shows that the number of new cases in recent years has stabilized between 622 and 713. 34  the number of cases per judge lies below that of high court justices in the Member States. 35 Up through 2014, one can even observe an increase in the number of disposed cases as well as shorter disposition times. According to former ECJ President Vassilios Skouris, the improvement is due to more efficient working methods and new procedural avenues to accelerate litigation. 36 Also, one possible explanation-though a mere suspicion-may be that there were no essential personnel changes at the ECJ in 2014.
Consequently, the difficulties of the EU's jurisprudence are not rooted in case load or the capacities of the judges, nor will possible solutions originate there. Solutions therefore must be sought in the substantial challenges of the proceedings themselves.

Adjudication in a Multi-Level System
The preliminary rulings procedure is meant to ensure that EU law is applied evenly. The task is a difficult one as the character of EU law is merely fragmentary, meant to protect national legal orders and the sovereignty of Member States. Accordingly, EU law and Member State national law are complementary.
The ECJ's decisions under the preliminary rulings procedure are binding interpretations of the Treaties, Article 267 (1)(a) TFEU. Because Member State courts are the actors who refer questions for preliminary ruling, the procedures are always embedded in a national context. For any given ruling, it would be possible to evaluate and decide in light of how it will affect other Member States, but this is seldom done. As currently organized, the ECJ is unable to foresee the effects of its rulings. The judges are highly qualified jurists who have distinguished themselves first within their own legal systems, and they possess excellent knowledge of European and international law. However, it is virtually impossible to require that they should know about the other Member States' legal orders, and the resources are simply not available by which to compensate for this knowledge deficit. To be sure, it is also incumbent upon the governments to brief the Court on foreseeable effects of a preliminary ruling beyond the referring state. 37 Without a doubt, foreseeing such effects is an enormous task. But then again it can have an undesirable effect on otherwise well-balanced systems in the Member States if effects of a judgment are not properly foreseen. It might, for example, lead to overregulation if functionally equivalent protections in Member State law are not accounted for. Employment law provides a good example of this. The sources of employment law are very complex, differ among Member States, and have different effects. Overly broad statements not expressly limited to the facts of a case can produce a situation where a well-balanced relationship between employer and employee interests in a given national legal order tilts prejudicially one way or the other. The problem becomes acute when the reasoning fails to address the possibility that national legal regimes may provide alternative protections.

Poor Quality of European Legislation
What has been discerned about the judiciary applies as well to EU legislation. It is true that during the legislative process, national legal orders are compared in order to establish the reasonable basis for harmonization. Yet no further attempt is made to foresee the effects, which above all would have the secondary consequence of unburdening the ECJ. Moreover, the statutory texts in different languages are all equally binding whereas the possibility of totally accurate translations is subject to the limitations of language itself. This is particularly serious as it is common for the ECJ to engage in plain language statutory interpretation. Ultimately, any reform of the jurisdiction of the EU will not be able to ameliorate these two circumstances.

Different Legal Backgrounds of the Judges
The Member States' national legal systems may have common roots in Roman law, 38 but beyond that there is no common legal tradition. Since the beginning of the ECJ, no independent European understanding of law has emerged. Quite the opposite, the working methods and legal traditions of the individual judges bear the imprint of their national legal orders to a large extent and differ from one another significantly. 39 Despite that for practical reasons cases are decided not by the full ECJ, but rather by panels of three, five or-rarely-fifteen judges, the diversity still necessitates a balancing among traditions of the participating judges. In light of this, former ECJ Judge Ulrich Everling has noted it is surprising that the community of judges were able to adopt a judicial practice that the European legal community, in particular those tasked with applying the law, could ever accept in the first place.

Diversity of Views on the Court and Historical Development
A main point of criticism we have already identified is the fact that opinions often contain unduly brief reasoning or lack reasoning altogether. This mode of rendering decisions is traceable to two circumstances. For one thing, the ECJ was founded upon the French law of administrative procedure. 40 It even adopted, and has maintained to this day, the terse French style of judgments. The other thing is that, while judges can often agree on the result, they frequently part ways on the reasons. 41 To avoid overly time-consuming deliberations, they are thus prone to strike out controversial passages from the reasoning. 42 This "striking technique" (German Streichtechnik) contributes to the brevity of stated reasons. 43

The Problem of Languages
An institution involving judges, Advocates General, référendaires, and staff from twenty-eight Member States needs a common working language. At the ECJ, it is French, which has advantages and disadvantages. A common language contributes to the cohesiveness of the institutions. Moreover, the use of French forces the judges to reflect anew on their positions because they must give explanations in a language not their own and thus in another terminological context.
The disadvantages arise primarily for non-Francophone judges. A judgment written in one's own language will, as a rule, be more precise and, thus, more persuasive. Also, not all terms of art will have a French counterpart. Cf. Woods, supra note 11, at 345 ("The judgment is an expression of the form of agreement rather than necessarily a record of a logical argument : : : "). far-reaching consequences. The criticism levelled against condensed reasoning of opinions again figures prominently here. If judgments are to be enforced in all Member States, national judges presumably must be able to understand them. Especially if a judgment refers to legal concepts or institutions not formally present, or not present in a given form in some Member State, then where there is no exact translation, the judgment must do more in the way of outlining and explaining those concepts or institutions. 44 Due to the diversity of languages, judges also cannot take into account any relevant literature written in a language they do not command. The high cost of translation means that more extensive works do not appear in translation, which disadvantages the discourse with legal scholarship, which frequently operates just at the national level.

Universal Responsibilities of ECJ Panels Instead of Specialization
In many Member States there are specialized tribunals on which expert judges are empaneled for areas of law that are complex or exhibit other special features. 45 This is the only way to ensure that judgments of sufficient quality issue within a short period of time.
The ECJ has done without this kind of specialization so as not to let the legal tradition of one Member State loom too large in any area of law. Although EU law has come to encompass a multitude of areas of law, every judge is still supposed to decide in every one of them. To this end, judges must perpetually acquaint themselves with one subject matter after another, which the judges themselves feel to be very taxing. Lasting engagement with one area of law yields deeper knowledge of that area and enables judges to dispose of cases in that area more quickly. It not only shortens the proceedings and is cost-efficient, but also the time saved allows judges to engage in more extensive research in their specialized area of law. It thus becomes possible to accumulate a pool of knowledge, even one that can be transmitted to the next generation, when a specialist judge leaves the bench. 46 The role of the ECJ is interesting in light of this universal responsibility. The qualifications for appointment to the ECJ correspond to those for appointment as a national constitutional court justice. The ECJ is tasked with ruling on a broader range of issues than just those arising under the primary EU law, however, which is comparable in many respects to national constitutional law. Within the confines of the preliminary rulings procedure-the most significant type of proceeding there-the ECJ rules on and interprets secondary law. The judicial activities under the preliminary rulings procedure strongly resemble those of special national tribunals. The ECJ thus fulfils a dual role as both a constitutional and a special jurisdiction court, though the latter activity is much more pronounced.
With secondary law expanding continually, and in light of the fact that the Member States do not all have separate constitutional jurisdictions but instead have instituted specialized tribunals to a greater or lesser extent across their court systems, it is not easy to comprehend why the ECJ should be averse to specialization. One veiled piece of evidence, that continuity of personnel and deepened knowledge in one body of law also holds advantages for the ECJ, appears from the reality of the past two decades, in which we have seen cautious specialization among the Judges-Rapporteur. The President of the ECJ sometimes assigns additional cases, referred in a given area of law, to judges who have already worked on a referral involving a particular directive in the past. Certain duos of a Judge-Rapporteur and an Advocate General have made their marks on lines of cases this way.

IV. Specialization in the Preliminary Rulings Procedure as a Rewarding Pursuit
The improvements that stand to be achieved through introduction of a specialized preliminary rulings procedure are aimed at garnering greater acceptance of the jurisdiction of the EU in the Member States. Specialization is a way to make judgments easier to understand and litigation results more predictable. 48 1. Benefits 1.1 Systematic Development in Subject Areas and Legal Certainty for Those Who Apply the Law Specialization can help boost systematic development in individual areas of law and consistency among judgments. 49 The prerequisite for developing a coherent system of law is continuity within the judiciary. 50 The current Chambers system at the ECJ entails cases arising in substantially similar areas of the law being decided by shifting panels of varying composition. The current design guarantees that one decision after another will be taken on the basis of minimal consensus. 51 A smaller, not constantly, shifting composition would facilitate compromise in the long run and thereby enable systematic development in a given area of law. 52 Systematic development eventually leads to greater legal certainty and clarity about the law for those who must apply it. 53 Not until a stable, uniform, jurisprudence has developed will courts in the Member States be able to resolve similarly situated cases themselves without having to rely on assistance from the ECJ as they have done in many instances so far. A coherent systematic development thus contributes to lowering the number of procedures.

Specialized Knowledge and More In-Depth Reasoning
Specialization alone is certainly not capable of altering the traditional form of written opinions. It does, however, contribute to letting the same judges grapple with one area of law over a longer time frame. 54 Such continuity is a prerequisite to a judge attaining special expertise in an area of law. Knowledge specific to an area of law, accumulated over time, does have the potential to lead to more in-depth reasoning of judgments. 55 If there were specialized chambers, the composition of which were not constantly shifting, the necessity of striking out passages of an opinion could be expected to diminish. Increased knowledge of a subject matter is also closely related to systematic development. It would allow the judges to communicate their thinking to the public more easily through their written decisions and thereby promote greater acceptance in the Member States.

Better Foreseeability of Effects
In the long run, judges who hear numerous cases arising in different Member States in one subject area learn not just about special features of national legal orders, but also about special features of the respective domains of life. Thus, specialized judges are better able to understand, from legal as well as factual perspectives, what effects their decisions will produce, and can better foresee the effect of judgments without having to expend additional resources.

Shorter Duration of Proceedings and Better Cost Efficiency
Shorter proceedings and the attendant gain in cost efficiency are momentous arguments in favor of specialization. 56 Specialized judges with great knowledge of a particular subject are able to handle cases more quickly. 57 It saves them the long time it takes to get acquainted with unfamiliar subject matter, and thus they need not seek information beforehand about fundamental legislative value judgments or the European and national legal frameworks. 58 Shorter proceedings incur lower costs per case. Moreover, a coherent systematic development would result in fewer cases reaching the ECJ, which would lessen the case load. Potential cost savings, however, are not to be found at the level of judges themselves because their number is firmly prescribed in Article 19 (2) subparagraph 1 sentence 1 TEU. But potential savings would present themselves at the administrative level as well as with translation services. An added benefit would accrue from shorter proceedings at Member State level, which would in turn feed back into savings there.

Manageable Disadvantages 2.1 Non-Uniform Legal Development and Lack of Attention to Particular Legal Orders
Introducing specialization into the EU judicial system, of course, risks negatively affecting the coherence of EU law. 59 On the one hand, different interpretations of EU law could emerge if different courts or chambers adjudicate on similar legal issues in different contexts. It is also true that if some legal traditions no longer participate in continuing legal development in each area of law, then it may result in insufficient consideration of the vantage point from particular national legal regimes. On the other hand, the advantages of enabling judges to establish clear lines of decisions and a uniform jurisprudence are substantial as we have shown. Furthermore, the disadvantage can be made manageable, in part, through the way specialization is set up, and especially through the choice of judges.

Problems in Drawing the Boundaries of Jurisdiction
Every specialization encounters the problem of demarcating jurisdictional boundaries from one specialized panel to the next. Yet jurisdictional conflicts are resolvable. The solution lies in designating an organ to decide, in doubtful or conflicting cases, which court or panel shall take cognizance of a case. The fundamental possibility of drawing such boundaries is already apparent from the fact that many national legal orders maintain special jurisdictions or tribunals for certain subject matter. Here too, problems of delineating competences arise, but these problems are manageable in practice. 56 See Dehousse, supra note 46, at § § 4.1-4.2. 57 See Arnold, supra note 49, at 485; see also Bruff, supra note 55, at 331; Dreyfuss, supra note 55, at 378. But see Dreyfuss, supra note 49, at 23-24 (stating that he was unable to detect efficiency gains five years after the creation of a specialized court in the USA, but believing they may need longer to materialize). 58 E.g., Ehricke, supra note 53, at 816 (regarding German jurisdiction); see also Jurgen Blomeyer, Der Ruf nach dem spezialisierten und sachverständigen Richter, 1970 ZEITSCHRIFT FÜR RECHTSPOLITIK 153. 59 See Woods, supra note 11, at 348. Cf. Cheng, supra note 49, at 552-53.

C. Models of Reform Toward Specialization of European Union Jurisdiction
Whoever is satisfied that specialized EU jurisdiction will procure greater acceptance of its jurisprudence has to examine possible models for reform. Around the turn of the millennium there was discussion, in particular, of the possibility of setting up decentralized EU courts in all or some of the Member States. 60 Decentralization was viewed as a way to achieve greater proximity, by subject matter, between EU courts and the Member States, for example, a specialization in one or more individual Member States. Yet, this idea of decentralized EU courts was never agreed upon in the process of amending the European treaties. This Article looks at three models of reform for which there is room within the scope of the TFEU.

I. Specialized Court
Article 257 TFEU enables the European Parliament and the Council to set up specialized courts attached to the GC. The only such court set up so far has been the Civil Service Tribunal, which was integrated into the GC as of September 1, 2016, as we noted earlier. Specialized courts may be authorized to hear certain classes of action or proceedings brought in specific areas at first instance, per Article 257 (1) sentence 1 TFEU. An appeal, limited to points of law, may be lodged before the GC against decisions of the specialized courts. That is unless, in setting up the specialized court, the scope of appeal is expanded to include points of fact, Arts. 257 (3), 256 (2) subparagraph 1 TFEU. If the GC has rendered a decision, the ultimate possibility is to petition for review by the ECJ, Article 256 (2) subparagraph 2 TFEU. This last appeal, however, is limited to cases which pose a serious risk of affecting the unity or consistency of EU law.

II. Specialized Chambers at the General Court
The GC forms Chambers to render decisions. Pursuant to Article 25 of the Rules of Procedure of the General Court ("RPGC"), the GC shall lay down criteria by which cases are sent to Chambers. Article 25 (1) sentence 2 of the RPGC expressly provides that specialized chambers can be set up: "The General Court may make one or more Chambers responsible for hearing and determining cases in specific matters." After having previously assigned cases solely in the order in which they are entered at the Registry, 61 the plenum recently laid down new criteria. These criteria provide for civil service cases and cases concerning intellectual property to be heard by specialized chambers. 62 Specialization has, therefore, now been introduced at the level of the GC in two areas of law.
Presently, the GC has jurisdiction to hear only the types of actions or proceedings explicitly mentioned in Article 256 (1) TFEU. Article 256 (3) TFEU provides, however, the possibility that "in specific areas laid down by the Statute" the GC may be assigned jurisdiction to hear preliminary ruling procedures. 63 Therefore, to declare that the GC has jurisdiction to hear preliminary ruling procedures, at least in certain areas of law, would require an amendment to the Statute of the Court of Justice of the European Union ("Statute of the CJEU"). Article 281 (2) TFEU provides a detailed procedure for amending that statute. The ECJ and the Commission are empowered to initiate such legislation.

III. Specialized Chambers at the ECJ
Like the GC, the ECJ forms Chambers to hear cases and render decisions. In addition to Chambers of three and five judges there is-acting as panels-the Grand Chamber of 15 judges, as well as the full Court. Yet, unlike the General Court, the ECJ does not have a formal process by which cases are assigned to Chambers. Pursuant to Article 15 of the Statute of the CJEU, if a case reaches the ECJ, the President first designates a Judge-Rapporteur, who draws up a preliminary report for presentation to the general meeting of the Court. The preliminary report contains inter alia a proposal for which panel ("formation") is to be tasked with hearing the case, Article 59 (2) sentence 1 Statute of the CJEU. The general meeting of the Court, which is composed of all the ECJ's judges and Advocates-General, then decides which Chamber to charge with hearing the case, cf. Article 25 sentence 1 Statute of the CJEU. Typically, the Judge-Rapporteur is a member of this Chamber. By virtue of the fact that the President alone designates the Judge-Rapporteur, he or she has overriding influence over the eventual assignment to a panel. In choosing the Judge-Rapporteur, the President takes into consideration such factors as current work load and prior experience of the judges in the particular area of law, as well as their nationality. 64 If one were to set up special chambers at the ECJ, there are two ways to go about it: Either through purely discretionary actions by the President or in a legally binding fashion. The President could simply designate judges from a given Chamber as Judges-Rapporteur for a particular legal subject matter. Because in the vast majority of instances the general meeting assigns cases to the Chamber to which the Judge-Rapporteur belongs, the practical result would be a specialized chamber. This specialized chamber would be a non-binding establishment. Case assignments are for the President's own discretion, and the President is not bound to bring about specialization. By contrast, if a specialized chamber is meant to be a mandatory establishment, two steps must be taken. One, a particular Chamber must be designated as the specialized chamber, and two, it must be ensured that the President names one of the judges on that Chamber as Judge-Rapporteur. In other words, the mandatory version necessitates directing the President's discretion.

IV. Specialized Chambers at the ECJ as a Logical Step in the Development of the Jurisdiction of the European Union
Now that the three possible models have been sketched out, what remains is to evaluate them. What are the advantages and disadvantages of each? In doing so, it is important to maintain focus on the central role of preliminary ruling procedures in ensuring coherence of EU law. Further factors to be considered include the political will to institute reform or whether reform might prolong some proceedings.

Special Jurisdiction in Preliminary Ruling Procedures Requires Amendment to the TFEU
If specialized courts were to be instituted for certain areas of law, it would go a long way toward achieving specialization with numerous attendant advantages. 65 Nevertheless, because this Article addresses specialization of the jurisdiction of the EU in preliminary ruling procedures, due regard must be paid to whether specialized courts lex lata are even permitted to hear such procedures in the first place. Under Article 257 (1) TFEU, specialized courts may be established to hear "certain classes of action or proceeding." Even though "proceeding" is a broad term, it does not cover the preliminary rulings procedure. 66 This is apparent from systematic comparison with Article 256 TFEU, which concerns regulations of the GC, namely in paragraphs 1 and 2 as they pertain to its jurisdiction. Paragraph 3 was created specifically to deal with the preliminary rulings procedure. It lays down rules that differ from those applicable to other types of proceedings the GC has jurisdiction to hear and establishes a right to refer cases to the ECJ. Moreover, Article 256 paragraph 3 TFEU contains a stricter barrier to appeals. By contrast, Article 257 TFEU does not differentiate among types of proceedings. It is difficult to imagine that the Member States, as framers of the Treaties, would have intended to regulate the preliminary rulings procedure before the GC separately, but not make such a procedure subject to special rules before a specialized court. More likely, the comparison between Articles 256 and 257 TFEU indicates that the Member States considered, but rejected, the idea of empowering specialized courts for the preliminary rulings procedure.
Supposing even that the TFEU were to be amended, which is hardly imaginable given the state of politics at present, 67 it is not advisable to make use of specialized courts to effectuate specialization in preliminary ruling procedures. Specialized courts, unlike specialized chambers set up within the ECJ or the GC, offer less flexibility. 68 The judges assigned to a specialized court would be unavailable to take on other duties if there were a lighter case load at some time. Moreover, the duration from beginning to end of a litigation could increase significantly if a preliminary ruling procedure had to run its course through as many as three European instances before the legal dispute at the national level could be resolved. 69

Risks to Coherent European Union Jurisprudence Posed by Specialized Chambers at the General Court with Jurisdiction to Hear Preliminary Rulings Procedures
Bringing specialization to the EU's jurisdiction to hear preliminary ruling procedures by transferring that jurisdiction in certain areas to the GC and setting up specialized chambers there is a solution that brings together all the advantages of specialization. First, specialization at the GC with jurisdiction to hear preliminary ruling procedures is advantageous because it is easier for the GC to react to increasing caseloads. 70 The number of judges sitting on the GC is provided in the Statute of the CJEU, Article 254 (1) TFEU. Yet the number of judges at the ECJ is governed by Article 19 (2) subparagraph 1 sentence 1 TEU. If caseloads were to rise, theoretically at least, it would be easier to appoint additional judges to the GC than to the ECJ, as it would require only an amendment to the Statute of the CJEU rather than the TEU. Practically speaking, however, the gain in flexibility is smaller than it might seem, as revealed by the debate surrounding expansion of the GC and elimination of the Civil Service Tribunal. For years it was impossible to fill open judgeships on the Civil Service Tribunal, nor was there agreement on how many new judgeships to create at the GC. 71 In the end, the number of judges at the GC was doubled and the Civil Service Tribunal eliminated in what was seen as the only way to assuage the fears of some 66 Member States that they stood to lose influence over EU jurisprudence if some could send only one while others sent two judges to the GC. But if the only choice is either to increase the number of judges by the number of Member States or do nothing, the gain in flexibility is greatly relativized.
Those considerations aside, it is hard to imagine the ECJ relinquishing its jurisdiction to hear preliminary ruling procedures and limiting itself purely to serving as an appeals court for this type of procedure. 72 Another good argument why preliminary ruling procedures should not be placed in the hands of specialized chambers at the GC is the coherence of EU law. 73 One of the most important tasks of the ECJ is to uphold the coherence of EU law. 74 Yet, an appeal from the GC to the ECJ lies subject to strict conditions only. 75 Article 256 (3) subparagraph 3 TFEU provides there must be "serious risk of the unity or consistency of Union law being affected." Thus, in a case of non-serious risk, the matter does not reach the ECJ and consequently, preliminary ruling procedures are subject to final judgment at two different levels. If one were to reach the ECJ, it furthermore would prolong litigation despite Article 62(a) of the Statute of the CJEU's requirement that the ECJ review the application urgently. 76

Specialized Chambers at the ECJ as the Best Solution
Setting up specialized chambers at the ECJ further develops the jurisdiction of the EU, but does so carefully. 77 This solution leaves intact both the pre-existing Chambers system as well as the distribution of jurisdiction between the ECJ and the GC. The changes it entails are courtinternal only. To be sure, specialized chambers would operate to constrain the President somewhat in assigning cases to Judges-Rapporteur whereas the President's flexibility in this area has been cited as one of the things that made shorter litigation times possible. If specialized jurisdictions are distributed sensibly among the Chambers, it should be possible to avoid placing an undue burden on just one Chamber. Furthermore, it is important to acknowledge that one can opt to specialize Chambers only partially, rather than conferring a single specialized jurisdiction on any one of them. Parallel to the special competence, each Chamber could thus retain a general jurisdiction under which it could be designated to hear cases that lie outside its subject matter focus.
Opponents of specialization at the ECJ maintain that thereafter some national legal regimes would drop out of legal finding in a given subject area. 78 This possibility cannot be ignored. To counter it, attention must be payed to making sure that judges who form a Chamber hail from different legal systems. To this end, the ECJ ought to group Member States together whose modes of legal thought or value systems are similar. 79 Moreover, one must consider that at present, the 72 See COUNCIL OF THE EUR. UNION, supra note 5, at 6 (illustrating this point as evidenced by the Court of Justice's report). See Hopt, supra note 77, at 596 (on the representation of interacting groups or bodies of law on two panels at the ECJ). But see Everling, supra note 39, at 407 (arguing that the legal regimes are so divergent that they are not easily amenable to grouping). majority of decisions are taken by Chambers of three and five judges. 80 It transpires that all legal regimes figure into deliberations only if the ECJ has convened the Full Court, an absolutely exceptional occurrence. The influence of all legal regimes in a given area of law-in the sense that none are ignored-is already slight as it stands. The only channel for an influence of all Member State regimes is through cases in a particular area of law being heard and decided from time to time by different Chambers. But the same set-up ensures that no judgments come down that contribute to systematic development, because each Chamber will be anxious to not bind other chambers by setting out fundamental principles that apply beyond the case at hand. 81 There is a concern that assigning some legal matters to specialized Chambers will produce incoherent development of EU law. Lines of decisions among special chambers could diverge from one Chamber to the next. This risk, however, is manageable. Even today the General Meeting assigns cases to the Grand Chamber when there seems to be a problem of coherence. 82 Also, the Grand Chamber is mandatorily called upon to preside whenever a Member State or EU institution party to the proceedings so requests, Article 16 (3) Statute of the CJEU. The Member States and institutions of the EU can also exercise this right when they regard a proceeding as essentially important to the coherence of EU law. Furthermore, a Chamber seized of a given procedure ought to be placed under a duty to refer it to the Grand Chamber whenever the presiding Chamber intends to deviate from the jurisprudence of another Chamber. It would have to be ensured, via amendment to Article 27 (1) of the ECJ Rules of Procedure (RPECJ) that at least one member of the specialized Chamber sits on the Grand Chamber in such event. The risk to coherence from instituting specialized Chambers thus is small and manageable.
While the disadvantages of specialized Chambers at the ECJ are not serious, this arrangement would carry with it all the previously mentioned advantages of specialization. Besides, this model of reform does not represent a radical departure from the existing architecture of the court-it is evolution rather than revolution. It is also relatively simple to realize politically, and is costeffective. It only necessitates amendments to the Statute of the CJEU and RPECJ. It does not require that a new court unit be created. On a per-procedure basis, it will even lead to cost savings because specialized judges will need less time to handle cases.
D. Setting Up a Special Chamber at the ECJ Because specialized Chambers at the ECJ represent the most compelling way to achieve specialization in the jurisdiction of the EU, the following sections examine how such a Chamber may be arranged.

I. Establishing Special Chambers on a Mandatory Basis
As previously mentioned, a special Chamber might be set up on a mandatory or permissive basis. A mandatory establishment requires an amendment to the RPECJ. Article 11 (2) of the Rules already contains a regulation conferring special responsibilities upon Chambers, namely for the urgent preliminary ruling procedure and for appeals lodged by the First Advocate General to uphold the unity or coherence of EU law against decisions of the GC. One can pick up where this specialization leaves off and insert a new, brief paragraph 2a: "The Court shall designate the jurisdictions of the chambers of three and five judges by fields of law." Moreover, paragraph 5 requires additional language: "The composition of the Chambers, the designation of the Chambers responsible for cases of the kind referred to in Article 107 and Articles 193 and 194 and the jurisdictions of the Chambers provided for in paragraph 2a shall be published in the Official Journal of the European Union." In order to steer the President's choice of the Judge-Rapporteur, the ECJ must supplement, with the Council's approval, Article 15 (1) of the RPECJ to read: "The President shall select the Judge-Rapporteur of the Chamber the Court has designated under Article 11 (2a) with jurisdiction to rule in the field of law mainly affecting the case." The other option is to set up specialized Chambers solely on the basis of court-internal guidelines and, thus, in a non-binding way. As opposed to instituting specialized Chambers on a mandatory basis, this would be the lesser solution, though politically it might be easier to enact. The court-internal guidelines would state which types of cases the President ought to assign to judges of which Chamber as Judges-Rapporteur. To imbue the guidelines with a certain binding quality, despite their status as soft law, they should be published on the homepage of the Court of Justice of the European Union. On one hand, this solution offers the benefit that the Council need not be involved because it does not require an amendment to the RPECJ. Furthermore, the President would retain a high degree of flexibility in selecting Judges-Rapporteur. On the other hand, it poses a long-term risk to systematic development if court-internal guidelines might be eliminated with little ado. Because the advantages of specialization accumulate over time, a long-term solution should be pursued that is not susceptible to possible modification on short notice. Such is guaranteed if the specialized Chamber is instituted by way of a modification to the RPECJ.

II. Partial Specialization
A specialized Chamber should not exercise one special jurisdiction exclusively, but rather should be just partially specialized. Parallel to their jurisdiction to hear cases in one or several limited areas of law, they retain general jurisdiction under which procedures from all other areas of law can be referred to a Chamber. There are two advantages to this: It limits the feared loss of flexibility in the event of specialization, and lets varying case-loads among Chambers be evened out by virtue of the option to designate more, or fewer, procedures to any one of them under the general jurisdiction. 83 There will also be less resistance to such a solution from among the ranks of judges because they will continue to hear cases dealing with many areas of law, which is part of the allure of working at the ECJ. As the ECJ itself must amend its procedural rules, it is important that the judges are open to specialization. Any reform should therefore avoid affecting the work of the judges in a way they perceive as negative.

III. Specialization Limited to a Few Areas of Law
The reverse implication of instituting only partial specialization among Chambers is that there will necessarily be areas of law that come under the general jurisdiction by default. Not every area of law over which the ECJ presides ought to be designated to a specialized Chamber. The study underlying this Article argues for specialization at the ECJ in the area of employment law. 84 Adjudication in the area of employment law is challenging. Alongside the individual's interests are collective concerns requiring due consideration, namely the interests of trade associations and labor unions as well as of employees' representatives, be it at particular workplaces or enterprise wide. Collective bargaining agreements and work agreements draw on sources of law unheard of in other areas of law. 85  Member States. They are grown up over the course of many decades and reflect a balance crafted by judiciary and legislature in the name of avoiding social unrest.
Specialization should not be limited to employment law. A specialized Chamber makes sense whenever deciding cases in one area of law requires relatively elaborate prior understanding of the factual or legal bases. In the last few years, specialization has been discussed, for example, for competition law, intellectual property law, and for trademark law. 86

IV. Choosing Judges for Specialized Chambers
When judges demonstrate expertise in an area of law for which a specialized Chamber has been created, they should as a matter of priority be assigned to that specialized Chamber. So far the RPECJ merely state in Article 11 (1) that the ECJ shall decide which judges are assigned to the three and five judge Chambers. The following should be added to this regulation: "When deciding which Judges shall be attached to Chambers responsible for certain areas of law, the Court shall consider the previous experience of the Judges." Successful specialization, however, does not create a prerequisite for judges to have prior expertise in an area of law that the Chamber they are about to join is set up to handle. The advantages of specialization materialize just as well where a highly qualified judge grapples with the material intensively for an extended period of time. 87

I. Specialization of Advocates General
Alternatively, or in addition to specialization of the judges, a specialization of the Advocates General should be considered. Pursuant to Article 16 (1) RPECJ, the First Advocate General is responsible for assigning cases. The practice is for assignments to rotate according to the order in which cases are registered, while at the same time no Advocate General is assigned to matters lodged from his or her country of origin so as to avoid conflicts of interest. Although firm criteria by which to assign cases are missing, specialization is a minor factor. As with the judges, such specialization can be done in a mandatory fashion by amending the RPECJ or by way of soft law.

II. Additional Référendaire Positions
Irrespective of specialization of judges or Advocates-General, it would be possible to employ specialist référendaires. "The creation or appointment of specialist conseillers référendaires would undoubtedly facilitate judicial understanding of many thorny issues linked to specific national contexts." 88 The French government has made a proposal along these lines: The corps of référendaires ought to be increased by an additional group of référendaires of different nationalities who would not be allocated to one judge. They would serve as a platform for exchange and as a resource to field questions of national law; and if need be, they could also tend to the training of the other référendaires.

III. Involvement of Industry and Labor
Involving qualified third parties can import another facet into the procedures, namely the insight of practical dealings. The idea here of letting interest groups intervene in international litigation is 86 See Skouris, supra note 70, at 6 (considering a specialized court for intellectual property); see also Everling, supra note 33, at 17 (considering specialized chambers in several areas of law). 87 Cf. Arnold, supra note 49, at 483. 88 Moreau, supra note 84, at 198. not new. Both the ECHR as well as the Rules of Court of the ECtHR provide for third party intervention in case of individual applications, inter alia by industry and labor associations, cf. Article 36 (2) ECHR and Article 44 of the ECtHR Rules of Court. The right of third parties to intervene may be a very wise, low-cost way for judges to obtain additional information characterized by ground-level awareness of the subject matter. Procedures in employment law are particularly suited to invite participation by management and labor as representatives of both sides.
The role of interest groups is not to bolster the litigants' positions in the underlying case, but instead to inject specific experience and insight into the procedure itself. Reservations against this manner of participation by third parties, on the basis that interest groups would exclusively pursue their own legal policy aims, are not persuasive as interest group representation would transpire openly via an institutionalized platform.
In order not to let participation by interest groups lead to longer litigation, the process should be integrated into the existing information and participation system under Article 23 Statute of the CJEU. The added expenditure would consist perhaps in providing notice to management and labor about pending cases in employment law. This would not require a disproportionate effort, provided that the obligation to inform is limited to leading EU level representative associations.
To avoid placing an undue burden on the ECJ, further precautions may be borrowed from the third party intervention process before the ECtHR. One such precaution is to provide, where an intervener petitions for leave to submit written comments, that the petition be duly reasoned with respect to why written comments are called for. 89 This is a way to ensure third party participation is limited to decisions that affect fundamental principles and does not crop up in every particular case. The ECtHR's practice of curtailing the length and content of written comments makes sense as a way of shielding the judges from an unmanageable quantity of submissions while enabling them to obtain information in a targeted fashion.
F. Five Concluding Theses on Specialization in the Preliminary Ruling Procedure 1. Specialization can increase the level of acceptance of ECJ jurisdiction in preliminary ruling procedures because it works to ameliorate the basis for criticism of the ECJ's decisions. 2. Specialization can help produce greater legal certainty, more in-depth reasoning of judgments, shorter procedures and improved cost-efficiency. 3. The ECJ should be furnished with mandatory, partially specialized special jurisdiction Chambers. The allocation of jurisdiction between the ECJ and the GC in the area of preliminary ruling procedures should be maintained. 4. Specialization need not be limited to the panels themselves but rather can also take place at the level of the Advocates General or by creating additional référendaire positions. 5. A right of intervention for interest groups has the potential to sharpen the ECJ's ability to foresee the consequences of its judgments.
