Abstract

Deep-water technology and commercial interests have put the protection of underwater cultural heritage under considerable pressure in recent decades. Yet the 2001 UNESCO Convention has the potential to fend off the threat—if fully implemented. This article sets out the legislative duties States Parties have under one of the Convention's core provisions: Article 16. It requires States Parties to take a triad of legislative measures: they must enact prohibitions, impose criminal sanctions and establish corresponding jurisdiction over their nationals and vessels. In addition, the comprehensive protection of underwater cultural heritage also necessitates measures covering acts of corporate treasure hunters, even though this is not required by the Convention itself.

8 In order to fully implement art 16, States Parties are also required to take non-legislative steps. Of particular importance are prevention and dissemination measures, such as the distribution of information material to persons engaging in underwater explorations, see eg PJ O'Keefe, Shipwrecked Heritage: A Commentary on the UNESCO Convention on Underwater Cultural Heritage (Institute of Art and Law 2002) 109–10. Despite the practical significance of such steps, the present article focuses solely on the heart of art 16, that is, its legislative measures.

9 Notwithstanding the fact that France plays a particularly active role in the preservation of underwater cultural heritage, it has not fully implemented the Convention. So far, the criminal provision in the Code du patrimoine only covers underwater cultural heritage in waters subject to French sovereignty (internal and territorial waters) or where France exercises sovereign rights (contiguous zone); see Code du patrimoine, version consolidée au 1 janvier 2020, arts L532-1 to L532-14 read together with arts L544-5 to L544-11.

10 Switzerland ratified the Convention on 25 October 2019, see UNESCO <www.unesco.org/eri/la/convention.asp?KO=13520&language=E&order=alpha>. On the implementing legislation passed by the Swiss Federal Assembly before ratification, which is fraught by major deficiencies, see Petrig, A and Stemmler, M, ‘UNESCO-Übereinkommen über den Schutz des Unterwasserkulturerbes: Unvollständige Umsetzung durch die Schweiz’ (2020) 139(I) ZSR 4794Google Scholar; and below text relating to (n 115).

17 From UNESCO Convention art 1(1)(a)(i), (ii) and (iii) accrues that underwater cultural heritage is not limited to historic shipwrecks and their cargo; but as per Dromgoole, Underwater Cultural Heritage and International Law (n 13) 1, ‘shipwrecks are the predominant form of [underwater cultural heritage]’, on the basis of which we explain the challenges for the protection of underwater cultural heritage.

31 On the risks associated with treasure hunters, see C Forrest, International Law and the Protection of Cultural Heritage (Routledge 2010) 287–8; activities of treasure hunters have been a driving force for the adoption of the Convention; see S Dromgoole, ‘2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage’ (2003) 18 International Journal of Marine and Coastal Law 65. The term ‘corporate treasure hunters’ is also used by Y Winter and J Chambers-Letson, ‘Shipwrecked Sovereignty: Neoliberalism and a Disputed Sunken Treasure’ (2015) 43 Political Theory 297.

However, on land the protection of these sites against intrusions is considerably more difficult than at sea. This is evidenced by sites such as Herculaneum and Pompeii: preserved as of the time of the eruption of Mount Vesuvius 79 AD, they were subject to subsequent plundering; their status as ‘time capsules’ accordingly disputed by eg AE Cooley and MGL Cooley, Pompeii and Herculaneum: A Sourcebook (2nd edn, Routledge 2014) 1–2. Maritime ‘time capsules’ are of particular interest because they are ‘single period’ time capsules and thus differ from land sites, which generally include artefacts from different time periods, see Varmer, ‘The Case against the “Salvage” of the Cultural Heritage’ (n 36) 288.

Regarding underwater cultural heritage in or on the seabed in the contiguous zone, UNCLOS art 303(2) transfers certain competences to coastal States, yet its scope is rather obscure, see T Scovazzi, ‘Article 303’ in A Proelss (ed), United Nations Convention on the Law of the Sea: A Commentary (C.H.

68 ibid art 2(5), further elaborated in Rule 1 of the Annex; on the relevance of this principle, see Dromgoole, Underwater Cultural Heritage and International Law (n 13) 24. Yet it is important to note that according to both stipulations of the Convention, the preservation in situ of underwater cultural heritage is not an irrefutable dogma, but merely the first option to be considered. As per Rule 1 of the Annex, salvage activities are generally permissible if they make ‘a significant contribution to the protection or knowledge or enhancement of underwater cultural heritage’.

69 UNESCO Convention art 2(7), further elaborated in Rule 2 of the Annex.

70 ibid art 2(8); questions relating to the sovereign immunity of State vessels thus remain governed by other rules of international law, notably by UNCLOS arts 95 and 96.

72 UNESCO Convention arts 7–13.

73 ibid art 7; the provision merely refers to ‘the Rules’; this, at first sight cryptic, reference is clarified by arts 1(9) and 33 from which accrues that the capitalised ‘Rules’ are the rules contained in the Convention's Annex.

74 ibid art 8.

75 ibid arts 9(1) and 11(1); as regards the exclusive economic zone and the continental shelf, however, the reporting requirement is limited to zones of States Parties, see ibid art 9(1)(a) and (b).

76 ibid arts 10 and 12.

77 See Rau (n 13) 407, 422. Forrest, International Law and the Protection of Cultural Heritage (n 31) 350–6 uses the term ‘enforcement regime’ in a less comprehensive way; Dromgoole, Underwater Cultural Heritage and International Law (n 13) 283–5 categorises arts 14–16 as general ‘control mechanisms’ of the Convention relevant for all maritime zones.

86 Among them even staunch critics of main aspects of the Convention, such as the US and the UK: MJ Aznar and O Varmer, ‘The Titanic as Underwater Cultural Heritage: Challenges to its Legal International Protection’ (2013) 44 Ocean Development and International Law 101; see also O Varmer, ‘United States of America’ in S Dromgoole (ed), The Protection of the Underwater Cultural Heritage: National Perspectives in Light of the UNESCO Convention 2001 (2nd edn, Martinus Nijhoff 2006) 384–5. As per Dromgoole, Underwater Cultural Heritage and International Law (n 13) 307, the Rules ‘embody internationally accepted standards for the conduct of underwater archaeological activities’.

91 See on this O'Keefe, Shipwrecked Heritage (n 8) 109 and Rau (n 13) 423–4.

92 This finding is also bolstered by UNESCO Convention art 1(7), which defines ‘[a]ctivities incidentally affecting underwater cultural heritage’ as activities which ‘despite not having underwater cultural heritage as their primary object or one of their objects, may physically disturb or otherwise damage underwater cultural heritage’.

95 See on this also O'Keefe, Shipwrecked Heritage (n 8) 109, who states that ‘measures to be taken must ensure that nationals and vessels do not engage in the activity’; and Rau (n 13) 424, who acknowledges the obligation of the States Parties to take ‘further legislative action’ (emphasis added) in addition to prohibitions.

Many of these capabilities are associated with corporations: see eg Dromgoole, Underwater Cultural Heritage and International Law (n 13) 6; Mohd Nor and Zahid (n 41) 134.

113 See, on the exploitation of insufficient State protection of underwater cultural heritage by treasure hunters, Villegas Zamora (n 48) 22.

114 Regarding the necessity of such action by maritime States, see Dromgoole, ‘Editor's Introduction’ (n 71) xxvii–xxviii; see, on the corresponding feature of art 16, Boesten (n 98) 174–5.

115 See Arrêté fédéral portant approbation et mise en œuvre de la convention sur la protection du patrimoine culturel subaquatique (modification de la loi sur le transfert des biens culturels et de la loi fédérale sur la navigation maritime sous pavillon suisse) (translation: Federal decree regarding the adoption and implementation of the Convention on the Protection of the Underwater Cultural Heritage), Feuille Fédérale (CH) 2019 4385, 4388.

119 Other provisions of the Convention that refer to the taking of measures are art 2(4), which requires States Parties to take ‘all appropriate’ and ‘necessary’ measures to protect underwater cultural heritage in general, see above Part IV, Section B; arts 10(4)–(6) and 12(3), (4), (6), which concern the adoption of protective measures regarding specific finds of underwater cultural heritage; art 13, which aims at measures securing the compliance of government ships with the provisions of the Convention in the different maritime zones; arts 19(4) and 20, which oblige States Parties to disseminate various kinds of information related to underwater cultural heritage.

122 UNESCO Convention art 17(1).

123 See on this also O'Keefe, Shipwrecked Heritage (n 8) 112, who discusses inter alia imprisonment as a suitable punishment under art 17(2).

124 See on this Part IV, Section A.

125 Rau (n 13) 437, as per whom both principles are arguably also inherent in UNESCO Convention arts 10(4) and 12(3).

126 See, on this approach in general, Dörr (n 88) 603–5. Doctrine is divided whether it is necessary that the ‘external’ treaty is ratified by all States party to the treaty subject to interpretation: C McLachlan, ‘The Principle of Systemic Integration and Article 31(3)(c) of the Vienna Convention’ (2005) 54 ICLQ 313–15, discusses various meanings that could be given to the words ‘applicable in the relations between the parties’ in art 31(1)(c) VCLT; M Herdegen, ‘Interpretation in International Law’ Max Planck Encyclopedia of Public International Law (last updated March 2013) para 24 <http://opil.ouplaw.com> argues for complete identity between the States parties to an ‘external’ treaty and to the treaty subject to interpretation. Since we do not adhere to this view, but rather to the broader reading of the requirement ‘applicable in the relations between the parties’, it does not matter that the two external international agreements of interest here—those regarding the M/S Estonia and the RMS Titanic—have not been ratified by any State Party to the UNESCO Convention.

According to art 11(2), the Agreement enters into force as soon as two States consent to be bound by it. So far, the UK consented, while the US signed the Agreement subject to the enactment of implementing legislation. The US Congress has not yet acted upon this: see US National Oceanic and Atmospheric Administration, Office of General Counsel, ‘R.M.S Titanic – Legislation’ (30 May 2018) <www.gc.noaa.gov/gcil_titanic-legislation.html>; see also the ‘Status List’ on the Agreement available at UK The National Archives, Foreign and Commonwealth Office, ‘Depositary’ (27 July 2008) <https://webarchive.nationalarchives.gov.uk/tna/20080727163407/ http://www.fco.gov.uk/en/about-the-fco/publications/treaties/depositary>.

146 The comparison of international norms with domestic rules is, however, not foreign to international law; the most prominent example is the identification of general principles of law in the sense of art 38(1)(c) of the Statute of the International Court of Justice (adopted 26 June 1945, entered into force 24 October 1945) 33 UNTS 21: see P de Cruz, ‘Comparative Law, Functions and Methods’, Max Planck Encyclopedia of Public International Law (last updated April 2009) paras 51–54 <http://opil.ouplaw.com>; another example for gaining insights from a comparison of domestic rules is the identification of ‘constitutional traditions common to the Member States’ pursuant to art 6(3) of the consolidated version of the Treaty on European Union [2016] OJ C202/13: see U Kischel, Comparative Law (Oxford University Press 2019) 84–5.

150 Introductory Text to the Protection of Military Remains Act 1986. While the protection of human remains has been the driving force behind the adoption of the Act, this is not reflected by its wording since the term ‘remains’ also covers ‘cargo, munitions, apparel or personal effects’; see S Dromgoole, ‘Military Remains on and Around the Coast of the United Kingdom: Statutory Mechanisms of Protection’ (1996) 11 International Journal of Marine and Coastal Law 33–4.

151 Compare Protection of Military Remains Act 1986, section 1, with UNESCO Convention art 1.

153 See (n 140) and relating text.

154 Protection of Military Remains Act 1986, section 3(1); section 3(1)(b)(iv) was amended by The Companies Act 2006 (Consequential Amendments, Transitional Provisions and Savings) Order 2009, SI 2009/1941, sched 1, section 69, with the effect that companies ‘registered under the Companies Act 2006’ became liable under the Act. Notwithstanding the specific rules of the Protection of Military Remains Act 1986, the UK government only began to designate shipwrecks as controlled sites or protected places in 2002; seemingly, the mere existence of the Act was a sufficient deterrent for a considerable period of time: Dromgoole, ‘United Kingdom’ (n 132) 330–1.

159 The negotiations were not recorded in detail, but can be retraced by having recourse to UNESCO documents and relevant scholarly writings; on UNESCO documents, see R Garabello, ‘The Negotiating History of the Convention on the Protection of the Underwater Cultural Heritage’ in R Garabello and T Scovazzi (eds), The Protection of the Underwater Cultural Heritage: Before and After the 2001 UNESCO Convention (Martinus Nijhoff 2003) 92–3 and 159–61.

160 On particularly contentious points, see T Scovazzi, ‘The 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage’ in G Camarda and T Scovazzi (eds), The Protection of the Underwater Cultural Heritage: Legal Aspects (Giuffrè Editore 2002) 120–30.

161 O'Keefe, Shipwrecked Heritage (n 8) 14–16. UNCLOS contains provisions on the protection of underwater cultural heritage (especially arts 149 and 303); however, it does not establish a comprehensive protection regime comparable to the UNESCO Convention. UNCLOS is not considered any further here, but see T Scovazzi, ‘Article 149’ in A Proelss (ed), United Nations Convention on the Law of the Sea: A Commentary (C.H. Beck 2017) 1052–8; Scovazzi, ‘Article 303’ (n 57) 1950–61.

163 Strati (n 148) 1; as per O'Keefe, Shipwrecked Heritage (n 8) 23, ‘the ILA Draft did indeed act as a blueprint for the development of the UNESCO Convention on the Protection of the Underwater Cultural Heritage’ (italics omitted).

164 On the substantive linkage between the provisions: Dromgoole, Underwater Cultural Heritage and International Law (n 13) 283–4; Rau (n 13) 438, n 208.

165 Art 5 ILA Draft featured a particular kind of coastal State jurisdiction: the ‘cultural heritage zone’, which States Parties would have been free to establish and which, as per art 1(3) ILA Draft, paralleled the extent of the continental shelf: Dromgoole, Underwater Cultural Heritage and International Law (n 13) 50; Cultural Heritage Law Committee (n 16) 436–7, 439.

167 See Garabello (n 159) 180.

168 On the cultural heritage zone, see above (n 165). In essence, prohibitions under art 8 must cover activities in maritime zones under the jurisdiction of non-States Parties, on the continental shelf of States Parties that chose not to establish a cultural heritage zone, and in areas beyond relevant State jurisdiction.

169 See above Part IV, Section A.

172 Reprinted in Dromgoole and Gaskell (n 112) 193–206. As per O'Keefe, Shipwrecked Heritage (n 8) 29, the draft was not subject to negotiations until April 1999; the first meeting of governmental experts in 1998 solely served as an exchange of views. The draft was jointly presented by UNESCO and DOALOS; but due to criticism regarding DOALOS’ authority to participate in the process, it assumed a fairly restrained role in the ensuing discussions.

201 The observations of Garabello (n 159) 111 substantiate this finding. As per Dromgoole, Underwater Cultural Heritage and International Law (n 13) 242, 244, the nationality principle allows for ‘legal entities’ to be brought within protective schemes for underwater cultural heritage, but she does not refer to the UNESCO Convention in this context.

202 See UNESCO Convention art 31.

203 See Henn (n 45) 159 who qualifies the US salvage industry as ‘the strongest, largest, best funded, and most technologically advanced in the world’; and Villegas Zamora (n 48) 22 describing the regional shift in commercial pillage activities. The San José is, again, illustrative as the two corporate treasure hunters involved in the search for its wreck off the coast of Colombia have their seats in the US and Switzerland respectively, see Drye (n 194); see on the issue also above Part IV, Section B.
