The need for a new federal constitution was first announced officially at the 17th Congress of the Communist Party of Czechoslovakia in spring 1986. A working group fronted by Marián Čalfa was set up in 1987 to draft this, and in November 1988, a 153-strong committee of the Communist Party and the National Front was created, led by Miloš Jakeš. The constitution was expected to be enacted after the 18th Congress of the Communist Party, during the course of 1990. In its last draft, it was to be a single constitution serving both the federation and the two republics and, in contrast with its predecessor, did not include the leading role of the Communist Party, and somewhat expanded the list of basic human rights.
