The Planning and Development Act 2005 (PD Act) provides two procedures by which region schemes may be amended (part 4). The first follows the procedures observed when preparing a scheme itself, involving among other things, approval by the Governor and tabling in both Houses of Parliament where motions to disallow the amendment may be passed (section 35). This is referred to as a 'substantial' or 'major' amendment.
The second procedure involves matters which in the opinion of the WAPC do not involve a substantial alteration to the scheme and are referred to as 'non-substantial' or 'minor' amendments (section 57). The terms 'major' and 'minor' will be used in this policy for convenience.
