In Catholic canon law, ius remonstrandi (Latin: "right of objection") refers to the right in law to protest a Papal bull, edict or law.
The right is usually reserved for a Catholic bishop or other high-ranking church official.
In 1994, Belgian politician and canon law scholar Rik Torfs appealed to bishops to use their ius remonstrandi to protest the papal letter ordinatio sacerdotalis, which sought to close the debate on allowing women into priesthood.
