The 1977 Constitution was long and detailed, including twenty-eight more articles than the 1936 Soviet Constitution and explicitly defined the division of responsibilities between the Central Government in Moscow and the governments of the republics. Later chapters established principles for economic management and cultural relations. The 1977 Constitution included Article 72, which granting the official right of constituent republics to secede from the Soviet Union promised in previous constitutions. However, Articles 74 and 75 stated that when a Soviet constituency introduced laws in contradiction to Supreme Soviet, the laws of the Supreme Soviet would supersede any legal difference, but the Union law which regulated the secession was not provided until the last days of the Soviet Union.
