Pope Paul VI instituted the rule out of respect for the elderly cardinals who would find a strenuous trip to the Vatican and conclave to be a hardship. It also has a practical purpose. The number of electors is limited to 120. Before a pope could only appoint a new cardinal if one of the elderly died. Now the pope can look at the list of cardinals due to retire that year and appoint a number of new cardinals to fill the coming vacancies to maintain the number at, or near, 120. Most of the retired cardinals still remain active, to a degree, in work for the Church but no longer carry the burden of travel to elect a new pope.
