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".
Serbs of Croatia
In the spring of 1991, an open war broke out. The war ended with a Croatian military success in Operation Storm in 1995 and subsequent peaceful reintegration of the remaining renegade territory in eastern Slavonia in 1998 as a result of the signed Erdut Agreement from 1995. Local Serbs, on the ground that Agreement, established the Serb National Council and gained the right to establish the Joint Council of Municipalities.
