The Secretary of State may by regulations make supplementary, incidental, transitional, transitory or saving provision for the purposes of strategic planning board regulations.

Where, immediately before strategic planning board regulations establishing a strategic planning board come into force, a spatial development strategy is operative in relation to the area of a principal authority that is to be a constituent authority of the board, regulations under subsection (1) may include provision for that strategy to be treated, for the purposes of this Part or another enactment, as the operative spatial development strategy of the strategic planning board.

Where a strategic planning board has an operative spatial development strategy immediately before strategic planning board regulations that revoke the regulations that established that board come into force, regulations under subsection (1) may include provision for that strategy to be treated, for the purposes of this Part or another enactment, as the operative spatial development strategy of a prescribed principal authority or authorities.
