It was preceded by three constitutions: the so-called Constitution of Turnovo, adopted on April 16, 1879, the Constitution of December 6, 1947, the Constitution of May 18, 1971. , None of these constitutions provided a specialized state body for constitutional control. ,,The Constitution of 1971 explicitly stated that it was the National Assembly that could control that a law it had passed did not contravene the Constitution (Art. 85). The new Constitution adopted on July 12, 1991 by the Grand National Assembly provided for creation of a Constitutional Court (Chapter 8). After the entering into force of the Constitution, the Constitutional Court Act was passed (August 16, 1991). The Constitutional Court was constituted on October 3, 1991. On December 26, 1991, the Court approved the Rules of the Organization and Activities of the Constitutional Court, and by the end of the same year it passed two decisions on cases which it had been approached with. Like most of the Constitutional Courts in Europe, the Bulgarian Constitutional Court exercises post-promulgation (after the act’s publication) on the consistency of with the Constitution, and not pre-promulgation control. Besides the Bulgarian Constitutional Court is vested with a competence to interpret the Constitution (Art. 149 para 1 subpara 1). These decisions of the Constitutional Court are binding on all State institutions, including the National Assembly. They have an important preventive as they rule out the passage of legislation that contravenes the Constitution.
