Hungary and Poland experimented with constitutional supervision in the early 1980s. Hungary established the Council of Constitutional Law which was elected by the legislature and consisted of several leading jurists. It was empowered to review the constitutionality and legality of statutes, administrative regulations and other normative documents; however, if the agency in question failed to heed its advice, it needed to petition the legislature. In 1989, the Soviets established the Constitutional Supervision Committee which "was subordinate only to the USSR constitution." It was empowered "to review the constitutionality and legality of a range of state acts of the USSR and its republics. Its jurisdiction included laws [passed by the legislature], decrees of the Supreme Soviet's Presidium, union republic constitutions and laws, some central administrative decrees, Supreme Court explanations, and other central normative documents." If the committee deemed the legislature to have breached legality, the legislature was obliged to discuss the issue, but it could reject it if more than two-thirds voted against the findings of the Constitutional Supervision Committee. While it was constitutionally powerful, it lacked enforcement powers, it was often ignored and it failed to defend the constitution during the coup against Mikhail Gorbachev.
