Constitutional Court of Russia
In October 1991 he became a judge of the Constitutional Court of Russia and on 1 November was elected the court's first (and only) chairman with unlimited tenure. During the Russian constitutional crisis of 1992-1993, Zorkin and the Constitutional Court collided with President Yeltsin on a number of issues, incl. his decision to ban the CPSU and (later) the National Salvation Front. On 30 November 1992, the court overruled Yeltsin's decision to disband the "local branches" of the Communist Party (court maintained that disbanding the ruling bodies of the party was lawful).
