Treason Act 1442

The Treason Act 1442 was an act of the Parliament of England that made it high treason for any Welshman to "drive, bring, carry away, or withhold" any Englishman or any Englishman's horse, cattle or goods.
The act was due to expire after six years, but was renewed for a further six years by the Treason Act 1448, after which it was allowed to expire.

The whole act was repealed for England and Wales by section 1 of, and the schedule to, the Statute Law Revision Act 1863 and for Ireland by section 1 of, and the schedule to, the Statute Law (Ireland) Revision Act 1872.
