If at any time after a scheme under paragraph 1 has come into operation the Secretary of State considers it appropriate to do so, he may by order provide that the scheme shall for all purposes be deemed to have come into operation with such modifications as may be specified in the order.

An order under sub-paragraph (1) may make, with effect from the coming into force of the scheme, such provision as could have been made by the scheme, and in connection with giving effect to that provision from that time may contain such supplemental, consequential and transitional provision as the Secretary of State considers appropriate.

An order under sub-paragraph (1) is subject to the negative resolution procedure.
