Maritime Delimitation in the Black Sea case

The Case concerning maritime delimitation in the Black Sea (Romania v Ukraine) [2009] ICJ 3 was a decision of the International Court of Justice (ICJ). On September 16, 2004, Romania brought its case to the court after unsuccessful bilateral negotiations. On February 3, 2009, the court handed down its verdict, establishing a maritime boundary including the continental shelf and exclusive economic zones for Romania and Ukraine.

In 1997, Romania and Ukraine signed a treaty in which both states "reaffirm that the existing border between them is inviolable and therefore, they shall refrain, now and in future, from any attempt against the border, as well as from any demand, or act of, seizure and usurpation of part or all the territory of the Contracting Party".^[1] Both sides agreed that if no resolution on maritime borders could be reached within two years, either side could seek a final ruling from the International Court of Justice. Ten million tonnes of oil and a billion cubic meters of natural gas deposits were discovered under the seabed nearby.^[when?]

BP and Royal Dutch/Shell signed prospect contracts with Ukraine, and Total contracted with Romania. The Austrian OMV (the owner of Romania's largest oil company, Petrom) signed a contract with Naftogas of Ukraine and Chornomornaftogaz to participate in an auction of concession rights to the area.^{[citation needed]}

Because of its location, Snake Island (Serpents' Island) affected the maritime boundary between the two countries. If Snake Island was an island, its continental shelf area would be considered Ukrainian waters. If it was an islet, in accordance with international law, the maritime boundary between Romania and Ukraine would not take it into consideration. Romania claimed that Ukraine was developing Snake Island to prove it was an island, rather than an islet.^[2] In 2007, Ukraine founded a settlement, Bile, in Snake Island for the aforementioned purposes.^[3]

On 16 September 2004, Romania brought a case against Ukraine to the International Court of Justice, as part of a dispute over the maritime boundary between the two states in the Black Sea, and claimed that Snake island had no socioeconomic significance.^[4] Islands are generally considered when boundaries are delimited by the states themselves or by a third party, such as the ICJ. Depending on individual circumstances, islands may theoretically have full, partial or no effect on determinations of entitlement to maritime areas.

However, in practice, even islets are often respected in maritime delimitation. For example, Aves Island was considered in the United States – Venezuela Maritime Boundary Treaty despite its small size and the fact that it was uninhabited. Most states do not distinguish between islands, under Article 121(3) of the United Nations Convention on the Law of the Sea, claim the shelf as an EEZ for all of their islands. Examples include the UK's Rockall, Japan's Okinotorishima, the US's Hawaiian Islands and a number of uninhabited islands along the equator and France's Clipperton and other islands.

Decisions by international courts, tribunals and other third-party dispute-resolution bodies have been less uniform. Although under Article 121(3), rocks are taken into account in delimiting maritime boundaries, they may be overlooked, discounted or enclaved if they have an inequitable distorting effect in light of their size and location. Even if such islands are not discounted, their influence on the delimitation may be minimal. Therefore, existing decisions have not reached the level of uniformity necessary for a rule of law.

Until this dispute, there had been no third-party international review of a particular feature's status as an Article 121(3) rock or Article 121(2) island, and the ICJ's decision was difficult to predict. If it declared Snake Island an island, in delimiting the maritime zones, the ICJ could consider "special" or "relevant" circumstances and give Snake Island full, partial or no effect on the boundary. On September 19, 2008, the ICJ closed its public hearing.^[5][6]

The court delivered its judgment on February 3, 2009,^[7] dividing the Black Sea with a line between the claims of each country.

Although under Article 121(3), rocks are taken into account in delimiting maritime boundaries, they may be overlooked, discounted or enclaved if they have an inequitable distorting effect in light of their size and location. Even if such islands are not discounted, their influence on the delimitation may be minimal.

On the Romanian side, the ICJ found that the landward end of the Sulina dyke, not the manmade end, should be the basis for the equidistance principle. The court noted that a dyke has a different function from a port, and only harbour works form part of the coast.^[8]

On the Ukrainian side, the court found that Snake Island did not form part of Ukraine's coastal configuration, explaining that "to count [Snake/Serpents'] Island as a relevant part of the coast would amount to grafting an extraneous element onto Ukraine's coastline; the consequence would be a judicial refashioning of Geography". The ICJ concluded that Snake Island "should have no effect on the delimitation in this case, other than that stemming from the role of the 12-nautical-mile arc of its territorial sea".^[8] While the judgment drew a line that was equitable for both parties, Romania received nearly 80% of the disputed area, allowing it to exploit a significant but undetermined portion of an estimated 100 billion cubic meters of natural gas deposits and 15 million tonnes of oil under the seabed.^[9]

However, according to UN International Court, Ukrainian commissioner Volodymyr Vasylenko, nearly all the oil and gas reserves are concentrated in the seabed that went to Ukraine.^[10]

Ukrainian President Viktor Yushchenko considered the ruling "just and final" and hoped that it would open "new opportunities for further fruitful cooperation in all sectors of the bilateral cooperation between Ukraine and Romania".^[11]

Likewise, Romanian Foreign Minister Cristian Diaconescu said his country had “many reasons to be satisfied by this ruling”,^[12] and Romanian President Traian Basescu said the verdict was "a major success for [Romania's] Foreign Ministry."^[13]
