299.Subsection (2) sets out the types of changes to an approved multi-area agreement that will require a revision proposal. Enlarging the area covered by the multi-area agreement may mean extending it to cover more of the area of a local authority that is already a signatory to the agreement, or, it may entail adding a local authority to the agreement whose area was previously outside the boundaries covered by the agreement. A revision proposal will not be required where a district council, in an area where there is also a county council, whose area was covered by the multi-area agreement but did not originally agree to it, subsequently decides that it does want to be party to the agreement.
