Isle of Man Act 1958

The Isle of Man Act 1958 (6 & 7 Eliz. 2. c. 11) restated the Common Purse Agreement between the United Kingdom and the Isle of Man.

It also ended control by the UK Treasury over Manx finances, and granted Tynwald powers to legislate with regard to customs, harbours, loans, mines, the police and the civil service.

The entire Act was repealed and replaced by the Isle of Man Act 1979.
