Treason Act 1814 became simply hanging, which was the method of execution for murder. The original penalty for women was to be drawn to the place of execution and burned at the stake. Burning was abolished by the Treason Act 1790 in Great Britain and by the Treason by Women Act (Ireland) 1796 in Ireland. The 1814 Act also permitted the King to authorise the use of an alternative method, beheading, which was not abolished until 1973 (although obsolete long before then). The Act was amended by the Crime and Disorder Act 1998 when the death penalty was abolished and replaced with imprisonment
Treason in the Republic of Ireland abolished until the Statute Law Revision Act 1983, but were incompatible with the 1937 constitution. The Treason Act 1939 gave legislative effect to Article 39, and provided for the imposition of the death penalty on persons convicted of committing treason within the state and on citizens convicted of committing treason against Ireland outside of the state. The Act also created the ancillary offences of encouraging, harbouring and comforting persons guilty of treason, and the offence of misprision of treason. No person has been charged under this Act. The Criminal Justice Act 1964 abolished capital punishment in the Republic of Ireland
