The Treason Act (Ireland) 1537 (28 Hen.

8. c. 7 (I), long title An Act of Slaunder) is an act of the former Parliament of Ireland which adds several offences to the law of treason in Ireland.

The Act makes the following conduct treason: The penalty for treason was death until 1998 when it was reduced to imprisonment for life or a lesser term.

During the debate on the abolition of the death penalty, the 7th Earl of Onslow said: My Lords, this is the most glorious piece of information one could possibly come across.

It has been worth waiting 30 years in your Lordships' House to know that slandering the sovereign in Ireland is still a hanging offence.
