Death

The current regulations regarding a papal interregnum—that is, a sede vacante ("vacant seat")—were promulgated by Pope John Paul II in his 1996 document Universi Dominici Gregis. During the sede vacante period, the College of Cardinals is collectively responsible for the government of the Church and of the Vatican itself, under the direction of the Camerlengo of the Holy Roman Church. Canon law specifically forbids the cardinals from introducing any innovation in the government of the Church during the vacancy of the Holy See. Any decision that requires the assent of the pope has to wait until the new pope has been elected and accepts office.

In recent centuries, when a pope was judged to have died, it was reportedly traditional for the cardinal camerlengo to confirm the death ceremonially by gently tapping the pope's head thrice with a silver hammer, calling his birth name each time. This was not done on the deaths of popes John Paul I and John Paul II. The cardinal camerlengo retrieves the Ring of the Fisherman and cuts it in two in the presence of the cardinals. The pope's seals are defaced, to keep them from ever being used again, and his personal apartment is sealed.

The body lies in state for several days before being interred in the crypt of a leading church or cathedral; all popes who have died in the 20th and 21st centuries have been interred in St. Peter's Basilica. A nine-day period of mourning (novendialis) follows the interment.
