The Republic of Srpska was created during the civil war in the territory of the former Yugoslav republic of Bosnia and Herzegovina in 1992-1995. Within the general framework of the agreement to establich peace in Bosnia and Herzegovina (the Dayton Peace Agreement), in Novembar 1995 it was recognized as an entity within Bosnia and Herzegovina. According to the Dayton Constitution, by its legal nature The Republic of Srpska was a confederative unit (with some elements of a federal unit) within Bosnia and Herzegovina as a confederation (with the some elements of a federation). During the last ten years, both Bosnia and Herzegovina and The Republic of Srpska underwent deep transformations. An indication of these deep transformations was the decision of the president of the Arbitration Tribunal to establish the District of Brcko as the third entity sui generis (in addition to The Republic of Srpska and The Federation of Bosnia and Herzegovina). Two basic levers in the anti-Dayton transformational processes which occurred in Bosnia and Herzegovina and its entities were The Constitutional Court of Bosnia and Herzegovina, as well as The High Representative of the international community for Bosnia and Herzegovina. The Constitutional Court of Bosnia and Herzegovina passed a series of anti-Dayton decisions; by its consequences the most far-reaching decision was related to the issue U 50/2000 which declared the constitutionality of the Bosniacs, the Croats and the Serbs in the entities. On the basis of that decision, in 2000 a set of amendments to The Constitution of The Republic of Srpska was passed which deeply changed the legal nature of The Republic of Srpska. It was transformed from a confederative into to a federal unit. The anti-Dayton activity of The High Representative of the international community is even more pronounced. He became the main constitutional and legislative factor of Bosnia and Herzegovina and its entities. Under his pressure, in 2003 new amendments to The Constitution of The Republic of Srpska were passed which further diminished the authorities in The Republic of Srpska, specially in the field of national defence and public security. The High Representative himself brought and declared dozens of laws for Bosnia and Herzegovina with which he transformed Bosnia and Herzegovina from the union of states into a federation. With the police reform he announced, he is preparing to regionalize Bosnia and Herzegovina, not taking into account the entity borders, and thus to pave the way for the final abolition of entities including The Republic of Srpska.
