Romanum decet pontificem (named for its Latin incipit: "it befits the Roman Pontiff") is a papal bull issued by Pope Innocent XII (1691—1700) on June 22, 1692, banning the office of Cardinal Nephew, limiting his successors to elevating only one cardinal relative,[1] eliminating various sinecures traditionally reserved for cardinal-nephews and capping the stipend or endowment the nephew of a pope could receive to 12,000 scudi.[2][3][4]
Romanum decet pontificem was later incorporated into the Code of Canon Law of 1917 in canons 240, 2; 1414, 4; and 1432, 1.[5] In 1694, Innocent XII's series of reforms was capped off with an expensive campaign to eliminate the venality of offices while reimbursing their current holders.[6]
However, following Romanun decet pontificem, only three of the eight popes of the 18th century did not make a nephew or brother cardinal.[7]
