s 26A Hierarchy of developments
(1) For the purposes of the planning Acts, a development belongs to one of the following categories— (a) the first (designated under section 3A(4)(b)), to be known as “ national developments ”, (b) the second, to be known as “ major developments ”, and (c) the third, to be known as “ local developments ”. (2) The Scottish Ministers are by regulations to describe classes of development other than national developments and assign each class to one or other of the categories mentioned in paragraphs (b) and (c) of subsection (1). (3) But the Scottish Ministers may, as respects a particular local development, direct that the development is to be dealt with as if (instead of being a local development) it were a major development. (4) Different provision may be made under subsection (2) for different areas. (5) Regulations under subsection (2) are not made unless a draft of the instrument containing the regulations has been laid before, and approved by resolution of, the Scottish Parliament.
