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.

Section 1 of the Crown Proceedings Act 1947 allows claims for which a petition would previously have been demanded to be brought in the courts directly as against any other defendant. However, a petition and fiat still appear to be necessary for personal claims against the monarch.

  • To obtain restitution of real or personal property of the subject which has found its way into the hands of the Crown, or compensation if restitution could not be made; or
  • To recover damages for breach of a contract made on behalf of the Crown, whether the breach was due to the acts or the omissions of servants of the Crown.

Where the Crown was in possession of the property of the applicant, and the title of the Crown appeared by record, as by inquest of office, the remedy was somewhat different and was called . Nor was the action available for breach of public duty, e.g. a failure to perform treaty obligations, nor for trespass or negligence or other torts by Crown servants.

Procedure

Common law

At common law the petition went through its earliest stages in Chancery. The petition suggested a right disputing the title of the Crown, and the Crown endorsed the petition . Then a commission was issued to inquire into the truth of the suggestion. After the return to the commission, the Attorney-General filed a response and the merits were determined as in any action. If the right was determined against the Crown, judgment of was given in favour of the applicant.
