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
On 7 November 2007, Serbia initialed a Stabilisation and Association Agreement (SAA) with the European Union, agreeing on the final version of the text to which no or little changes are to be made. This was the step immediately preceding the official signing that was expected to take place in 2008 and was a milestone in Serbia's accession negotiations. It was executed following the advice of chief war crimes prosecutor Carla Del Ponte, who advised the EU that the country was complying adequately with the tribunal but Ratko Mladić must be in The Hague prior to any official signing being able to take place. Mladić was subsequently arrested on 26 May 2011, and has since been extradited to the International Criminal Tribunal for the former Yugoslavia to stand trial. On 20 July, Goran Hadžić became the last indicted fugitive to be arrested.
