Petition of right
（重定向自Monstrans de droit）
In English law, a petition of right was a remedy available to subjects to recover property from the Crown.
Before the Crown Proceedings Act 1947, the British Crown could not be sued in contract. However, as it was seen to be desirable that Crown contractors could obtain redress, lest they be inhibited from taking on such work, the petition of right came to be used in such situations, especially after the Petitions of Right Act 1860 simplified the process. Before the petition could be heard by the courts, it had to be endorsed with the words fiat justitia on the advice of the Home Secretary and Attorney-General. This Latin phrase was normally translated as "Let right be done".
