Pope John Paul II's 1996 Constitution Universi Dominici Gregis banned conclave capitulations as well as the papal veto, which had already been eliminated by Pius X. He wrote: "I likewise forbid the Cardinals before the election to enter into any stipulations, committing themselves of common accord to a certain course of action should one of them be elevated to the Pontificate. These promises too, should any in fact be made, even under oath, I also declare null and void." List of conclave capitulations References Sources Baumgartner, Frederic J. 2003.
