Fiat justitia

Fiat justitia is a Latin phrase, meaning "Let justice be done". Historically in England, a warrant for a writ of error in Parliament or later a petition of right in the courts could be brought only after the king, or on his behalf the Home Secretary, had endorsed fiat justitia on a petition for such a warrant. It was a means of granting leave to appeal by exercise of the royal prerogative.
