The F1CMA shall cancel a reference under section 62(3) if it considers that the proposal to make arrangements of the kind mentioned in that reference has been abandoned.

The F1CMA may, if it considers that doing so is justified by the facts (including events occurring on or after the making of the reference concerned), treat a reference made under subsection (2) or (3) of section 62 as if it had been made under subsection (3) or (as the case may be) (2) of that section; and, in such cases, references in this Part to references under those enactments shall, so far as may be necessary, be construed accordingly.

Where, by virtue of subsection (2), the F1CMA treats a reference made under subsection (2) or (3) of section 62 as if it had been made under subsection (3) or (as the case may be) (2) of that section, paragraphs F2... 2, 7 and 8 of Schedule 7 shall, in particular, apply as if the reference had been made under subsection (3) or (as the case may be) (2) of that section instead of under subsection (2) or (3) of that section.

Subsection (5) applies in relation to F3... any order made under paragraph 2 of F4Schedule 7, which is in force immediately before the F1CMA, by virtue of subsection (2), treats a reference made under subsection (2) or (3) of section 62 as if it had been made under subsection (3) or (as the case may be) (2) of that section.

The Secretary of State may at any time vary a reference under section 62.

The Secretary of State shall consult the F1CMA before varying any such reference.

Subsection (7) shall not apply if the F1CMA has requested the variation concerned.

No variation by the Secretary of State under this section shall be capable of altering the consideration or considerations specified in the reference or the period permitted by virtue of section 65 within which the report of the F1CMA under that section is to be prepared and given to the Secretary of State.
