斯洛伐克社会主义共和国
On its entry into force on 1 January 1969, it created the Czech Socialist Republic and the Slovak Socialist Republic, both of them on an equal footing within the federation. The Act stipulated in article 142, paragraph 2, that both republics would in due course enact their own constitutions, and also envisaged the creation of three constitutional courts. The plan, however, was not followed through due to the onset of the "period of normalization".
