108.This section makes minor changes to section 46 of the 1997 Act which gives the Scottish Ministers the power to make directions to call in applications. The directions may apply to one or more planning authorities and may relate to an individual application or a class of applications as described in the directions. This section inserts a subsection (1A) giving the Scottish Ministers the power to either withdraw directions or modify existing directions by making further directions. Subsection (3) is amended consequentially to make explicit reference to subsection (1).
