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".
Treaties between the Republic of Croatia and the Holy See
Officially known in Croatian as "Ugovor između Svete Stolice i Republike Hrvatske o dušobrižništvu katoličkih vjernika, pripadnika oružanih snaga i redarstvenih službi Republike Hrvatske", this concordat obliges the Croatian state to integrate institutions of Catholic military chaplaincy in the Croatian military. It was ratified by the Croatian Parliament on 24 January 1997.
