Page "General Synod of the Church of England" Paragraph 34

Measures or canons must be passed by a majority of the members of each house of the synod.

Most other business can be passed by a majority of the members of the Synod overall.

However changes to church doctrine, rites and ceremonies, or the administration of the sacraments, can only be made in the form agreed by the House of Bishops.

Also, changes in the services of baptism or holy communion, and proposals for a union with any other church, cannot be approved unless they have also been approved by a majority of the diocesan synods.

Some Measures do not extend to the Diocese of Sodor and Man unless so provided by a measure passed by the Sodor and Man Diocesan Synod and approved by Tynwald.
