Without prejudice to article 22(1)(a), an application may be made to the Lands Tribunal under this article by owners of at least one quarter of the units for the variation or discharge of a rule (other than a rule in Part 2 of the Development Management Scheme) as it affects, or as the case may be would affect, all or some of the units forming the development.

In the case of an application made by owners of some (but not all) of the units forming the development, the units affected need not be the units which they own.

Paragraphs (5) to (7) of article 22 apply in relation to an order made by virtue of paragraph (1) varying or discharging a rule as they apply to an order under article 22(1)(a).
