Since 1993, the Sodor and Man Diocesan Synod has had power to enact measures making provision "with respect to any matter concerning the Church of England in the Island". If approved by Tynwald, a measure "shall have the force and effect of an Act of Tynwald upon the Royal Assent thereto being announced to Tynwald". Between 1979 and 1993, the Synod had similar powers, but limited to the extension to the Isle of Man of measures of the General Synod. Before 1994, royal assent was granted by Order in Council, as for a bill, but the power to grant royal assent to measures has now been delegated to the lieutenant governor. A Measure does not require promulgation.
Before what year was royal assent approved by Order in Council?
