(1) This section applies if—
(a) land ceases to be in a priority development area; and
(b) immediately before the cessation, a PDA development approval was in force for the land.
(2) On the cessation, the PDA development approval is taken to be an SPA development approval for the land that took effect at the same time as the PDA development approval.
(3) However, if an appeal under section 90 has been started, or is started within 20 business days after the cessation, the appeal may be decided under that section as if the cessation had not happened.
