Arbitration Commission of the Peace Conference on Yugoslavia
On 20 November 1991 Lord Carrington asked: "Can the internal boundaries between Croatia and Serbia and between Bosnia and Herzegovina and Serbia be regarded as frontiers in terms of public international law?" Applying the principle of "uti possidetis juris", the commission concluded on 11 January 1992, "The boundaries between Croatia and Serbia, between Bosnia and Herzegovina and Serbia, and possibly other adjacent independent states may not be altered except by agreement freely arrived at... Except where otherwise agreed, the former boundaries become frontiers protected by international law".
Accession of Serbia to the European Union
Deputy Prime Minister Božidar Đelić signed the Stabilisation and Association Agreement on 29 April 2008. Vojislav Koštunica, Serbian Prime Minister at the time, said on 1 May that Russian Foreign Minister Sergei Lavrov was right when he said that the SAA should have been signed. But one day later, on 2 May 2008, he vowed to annul the agreement after the election, calling it “a trick”, “Solana's agreement” and “the Tadić-Đelić SAA signature”. After the Serbian parliamentary election, 2008, a new parliamentary majority and government was formed and the SAA opposition was left without political power. The new Serbian Prime Minister, Mirko Cvetković, announced “"One of the first moves of the new government will be to submit the Stabilisation and Association Agreement with the European Union to the parliament for ratification."” As of January 2009 the Serbian government has started to implement its obligations under the agreement unilaterally. The effects remain to be evaluated by the European Commission.
