Abstract
The political regime in Bosnia and Herzegovina (BiH), according to most theorists, is a con-sociational system (see: Consociational Democracy). Veto rights represent one of the four fundamental characteristics of consociational democracy or " power sharing " as defined by Lijphart (group autonomy; proportional representation; participation of all in government; veto rights). Lijphart calls the veto, as the so-called negative rule of the minority, a mutual veto, which aims to ensure that the majority (alone) cannot reach a decision that would out-vote the minority in fields affecting its vital interests, and thus it ensures political protection to each segment (group) of the consociational society. Definition of the veto. In the constitutional-legal sense, the veto can be defined as the constitutional competence within the state institutions (president, parliament etc.), which can be used to block (permanently or temporarily) the enactment of a specific decision. Veto mechanisms can be classified in relation to different criteria-in relation to the competence bearer, we distinguish the veto of a legislative body and the veto of the head of state, and in relation to the effect, we distinguish an absolute and a suspensive veto. In relation to the scope of constitutional legal control, veto mechanisms can be divided into mechanisms that are subject to constitutional judicial control from the procedural and substantial aspect, and mechanisms that are not subject to supervision. Except for the abovementioned, veto mechanisms can also be conceived as a form of protection of specific interests or values that are in correlation with the state arrangement model, the nature of the political regime, minority groups, and so on.
