Page "Royal Assent" Paragraph 41

Royal Assent is not sufficient to give legal effect to an Act of Tynwald.

By ancient custom an Act did not come into force until it had been promulgated at an open-air sitting of Tynwald, usually held on Tynwald Hill at St John's on St John's Day ( 24 June ) but since the adoption of the Gregorian calendar in 1753 on 5 July ( or on the following Monday if 5 July is a Saturday or Sunday ).

Promulgation originally consisted of the reading of the Act in English and Manx, but after 1865 the reading of the title of the Act and a summary of each section were sufficient.

This was reduced in 1895 to the titles and a memorandum of the object and purport of the Act, and since 1988 only the short title and a summary of the long title have been read.
