EXPLANATORY NOTE (This note is not part of the Order) Section 2A of the Town and Country Planning Act 1990 (c. 8) (as inserted by section 31(2) of the Greater London Authority Act 2007 (c. 24)) gives the Mayor of London (“the Mayor”) power to direct that an application for planning permission of potential strategic importance (“PSI application”) be determined by him in place of the local planning authority. The Town and Country Planning (Mayor of London) Order 2008 ( S.I. 2008/580) (“the 2008 Order”) defines “PSI application” by reference to categories of development set out in Parts 1 to 4 of its Schedule. The 2008 Order also sets out the circumstances in which the Mayor's powers to give directions (including the power to direct a local planning authority to refuse a PSI application) may be exercised and makes procedural provision in connection with the exercise of those powers. Article 10 of this Order amends the 2008 Order to provide that the Mayor may direct that he is to determine a PSI application for development which falls with Category 3D of the Schedule to the 2008 Order. Category 3D covers development on land allocated as Green Belt or Metropolitan Open Land which would involve the construction of a building with a floorspace of more than 1,000 square metres or a material change in the use of such a building. Article 10 of this Order also inserts a new category of development into the Schedule to the 2008 Order. New Category 3J covers development of 50 or more houses, flats, or houses and flats. Applications for development which fall solely within Category 3J will be subject to a new procedure. The Mayor must be notified when a local planning authority is in receipt of an application in this category, but will not be required to respond (see article 4 of the 2008 Order, as amended by article 6 of this Order). The local planning authority will not be able to refuse the application without further notifying the Mayor, and the Mayor will have 21 days to decide whether to direct that the application be determined by him (see articles 5 and 7 of the 2008 Order, as amended by articles 7 and 9 of this Order). This Order also makes miscellaneous amendments to the 2008 Order, including to update out-of- date legislative references. A full impact assessment has not been produced for this instrument as no, or no significant, impact on the private, voluntary or public sector is foreseen. 6
