(Article VI(3)(a) of the Constitution)
The Constitutional Court has jurisdiction to decide as to whether any provision of an Entity's constitution or a law of an Entity is compatible with the Constitution of Bosnia and Herzegovina.
Although the Constitution of Bosnia and Herzegovina explicitly focuses only on 'provisions of an Entity's law', this also implies a review of constitutionality of laws of Bosnia and Herzegovina in accordance with the general task of the Court to uphold the Constitution of Bosnia and Herzegovina.
Under the Constitution, disputes may be referred only by a certain circle of authorised persons, i.e. a member of the Presidency of Bosnia and Herzegovina, the Chair of the Council of Ministers, the Chair or a Deputy Chair of either chamber of the Parliamentary Assembly, one-fourth of the members/delegates of either chamber of the Parliamentary Assembly, or one-fourth of either chamber of a legislature of an Entity.
