English Act of Parliament whose application to the Isle of Man became central to the legal aftermath of William Christian’s execution.

Christian was tried in Mann for treason arising from the events of 1651 and executed at Hango Hill on 2 January 1663. His son George Christian subsequently complained to Charles II that his father had been condemned and put to death despite claiming the benefit of the Act of General Pardon and Indemnity.

The matter was heard before the Privy Council. The Deemsters Thomas Norris and Hugh Cannell, Deputy-Governor Henry Nowell and other members of the Manx court were summoned to England to answer the complaint.

On 5 August 1663 the Lord Chief Justice of King’s Bench, the Lord Chief Baron of the Exchequer and the King’s Counsel gave their opinion that the Act “did and ought to be understood to extend into the Isle of Man” in the same way as to the King’s other dominions and plantations beyond the seas. Because it was a public general Act of Parliament, they held that the Manx judges should have taken notice of it even though it had not been pleaded and no proclamation of it had been made on the Island.

The Council ordered restitution of William Christian’s estate to his widow and children. A later order directed that the Council’s decision should be printed in the form normally used for Acts of Parliament so that the King’s intention to observe the Act of Indemnity should be publicly known.
