The Town and Country Planning (Mayor of London) Order 2008
Section 2A of the Town and Country Planning Act 1990 (c.8) (inserted by section 31 of the Greater London Authority Act 2007 (c.8)) gives the Mayor of London power to direct that applications for planning permission of potential strategic importance (“PSI applications”) must be determined by him in place of the local planning authority. Section 74(1B) of the 1990 Act (inserted by section 344 of the Greater London Authority Act 1999 (c.29)) enables provision to be made in a development order for enabling the Mayor to direct the local planning authority to refuse such an application.
