A determination by the CMA on an appeal—
must be contained in an order made by the CMA;
must set out the reasons for the determination;
takes effect at the time specified in the order or determined in accordance with provision made in the order;
must be notified by the CMA to the parties to the appeal;
must be published by the CMA—
as soon as reasonably practicable after the determination is made;
in a way the CMA considers appropriate to bring it to the attention of any person likely to be affected by it (other than a party to the appeal).
The CMA may exclude from publication any information it is satisfied is—
commercial information, the disclosure of which would, or in the CMA's opinion might, significantly harm the legitimate business interests of an undertaking to which it relates, or
information relating to the private affairs of an individual, the disclosure of which would, or in the CMA's opinion might, significantly harm the individual's interests.
The Authority must take such steps as it considers requisite for it to comply with an order of the CMA under subsection (1)(a).
The steps must be taken—
if a time is specified in (or is to be determined in accordance with) the order, within that time;
in any other case, within a reasonable time.
