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".
Republic of Serbian Krajina
Serbs became increasingly opposed to the policies of Franjo Tuđman, elected president of Croatia in April 1990, due to his overt desire for the creation of an independent Croatia. On 30 May 1990, the Serb Democratic Party (SDS) of Jovan Rašković broke all ties to the Croatian parliament. The following June in Knin, the SDS-led Serbs proclaimed the creation of the Association of Municipalities of Northern Dalmatia and Lika. In August 1990, the Serbs began what became known as the Log Revolution, where barricades of logs were placed across roads throughout the South as an expression of their secession from Croatia. This effectively cut Croatia in two, separating the coastal region of Dalmatia from the rest of the country. The Constitution of Croatia was passed in December 1990, which reduced the status of Serbs from "constituent" to a "national minority" in the same category with other groups such as Italians and Hungarians. Some would later justify their claim to an independent Serb state by arguing that the new constitution contradicted the 1974 Yugoslav Constitution, because in their view, Croatia was still legally governed by the Socialist Federal Republic of Yugoslavia, although this ignores the fact that Serbia's constitution, promulgated three months before Croatia's, also contained several provisions violating the 1974 Federal Constitution.
