1. Energy at Sea: Old Problems, New Challenges 22 October 2015 Delimitation Agreements: Common trends in a diverse world Sotiris-Ioannis Lekkas DPhil candidate, University of Oxford Stavros-Evdokimos Pantazopoulos PhD Candidate, European University Institute

2. Overview of the presentation  Objectives and scope  The Law of Maritime Boundary Delimitation  Energy considerations and maritime boundary delimitation  Substantive regulation of energy activities in maritime delimitation  Concluding remarks: common trends in a diverse world

3. Objectives  Mapping out the allocation of jurisdiction at sea amongst states  Relevance of energy considerations to the practice of maritime delimitation, especially in negotiation and conclusion of delimitation agreements

4. Scope (105 delimitations)  Energy considerations: relating to the exploration, exploitation, extraction, processing, production, refining, transport, transmission, or distribution of energy resources, materials and products (see Art 1(5) ECT)  Relevance of energy considerations either express or contextual as long as they can be specified

5. The Law of Maritime Boundary Delimitation  Rudimentary principles of the law of maritime delimitation are residual; they apply as long as there is no agreement to the contrary  Territorial sea: States may not extend their territorial sea beyond the median or equidistance line, unless there are historical or other ‘special’ circumstances that dictate the contrary  Continental shelf and Exclusive Economic Zone: delimitations were to be effected by agreement on the basis of equitable principles and taking into account of all the relevant circumstances

6. Three-tiered test for delimitation (ICJ, Maritime Delimitation in the Black Sea)  drawing of a provisional line that will be the median line ‘unless there are compelling reasons that make this unfeasible in the particular case’;  considering ‘whether there are factors calling for the adjustment or shifting of the provisional equidistance line in order to achieve an equitable result’;  ‘verify[ing] that the line … does not, as it stands, lead to an inequitable result by reason of any marked disproportion between the ration of the relevant coastal lengths and the ration between the relevant maritime area of each State by reference to the delimitation line’

7. Energy considerations and maritime boundary delimitation  Three ways that energy considerations have been raised explicitly in the context of maritime delimitation dispute settlement proceedings: 1. unity of resource deposits; 2. the role of the relative poverty in resources of one state; 3. the role of preexisting licences and concessions for the exploration and exploitation of mineral resources

8. Substantive regulation of energy activities in maritime delimitation  In general, maritime delimitation agreements contain very few, straightforward provisions (method of delimitation, agreed coordinates)  Late 1960s, early 1970s: North Sea delimitation agreements depart from that approach; specific provisions about existing licenses, first resource deposit clauses  Mid 1970s onwards: Provisions pledging co-operation in various sectors (eg agreements between Colombia and central American states)  See also 1977 CS: Greece-Italy and 1992 CS: Albania-Italy; both include compromissory clauses making dispute settlement proceedings mandatory

9. Substantive regulation of energy activities in maritime delimitation  What kind of energy activities? Almost invariably, exploration and exploitation of hydrocarbons  But see 1978 MB: Australia-Papua New Guinea (Torres Strait Treaty): energy production from water, currents and winds  Also, the provisional arrangement between Ireland and the UK on jurisdiction for renewable energy production activities in the still undelimited territorial sea area between Northern Ireland and Ireland

10. Resource Deposit Clauses: A valuable tool in maritime delimitations negotiations  Definition: ‘A provision that commits states to cooperate when a single resource extends across the boundary and part of the resource is exploitable from the other side of the boundary’ (Kwiatkowska 1993)  In the event straddling deposits are found: a duty to notify and to enter into negotiations or consultations with the other party with a view to achieve an equitable or proportionate solution  More rarely a procedure is provided in the case such negotiations or consultations fail to produce a solution, ranging from optional invitation of independent experts to mandatory arbitration

11. Concluding remarks: common trends in a diverse world  Although energy considerations provide more often than not the main thrust for the negotiation of such agreements, their role in the law of maritime delimitation in the narrow sense is marginal  The intensification of offshore activities, especially energy related ones, is reflected in delimitation treaties in the form of specific treaty provisions
