The Earl Marshal, a hereditary office held by the Duke of Norfolk, oversees the College, but he is not a member. He must give his written consent, called a warrant, before any new coat of arms can be issued. The Earl Marshal's court (called the Court of Chivalry) can hear cases about using coats arms, but the court has not sat since 1954. Usually the Earl Marshal usually leaves affairs to the professional heralds of the College.
