Thea act is written in the Anglo-Norman language. It was expressed to be passed because the Forcible Entry Act 1391 (15 Ric. 2. c. 2) was felt to be inadequate because it did not apply to persons committing forcible detainer after a peaceful entry or to persons who, having committed forcible detainer, had been expelled from the land before the justice of the peace arrived to arrest them, and because it did not provide for the punishment of a sheriff who failed to carry out the orders of the justice of the peace to execute the statute.
