Part 1: Digital Markets Chapter 5: Mergers Section 63: Delay to possible mergers etc
This section sets out restrictions on reportable events taking place.
	Subsection (1) provides that a designated undertaking or group member with a duty to report a reportable event (see section 57(1)) must not allow the event to take place until a report in relation to the event has been submitted to the CMA and the waiting period in relation to the event has expired.
	Subsection (2) defines the waiting period as the period of 5 working days beginning with the first working day after the day on which the CMA gives notice to the reporting person that it accepts their report is sufficient. "Working day" is defined in section 330.
	Subsection (3) provides that, where a reportable event takes place in breach of subsection (1), every person with a duty to report the event is to be treated as having breached subsection (1). This means that all members of a group will be treated as having failed to comply where one or some members have failed to do so.
	Subsection (4) permits the CMA to give its consent to a reportable event happening before the end of the waiting period, including before a report has been accepted by the CMA or submitted to the CMA. The CMA may also revoke its consent before the event takes place.
	Subsection (5) provides that the restrictions in subsection (1) do not apply in relation to a reportable event where the CMA gives and does not revoke its consent to the event taking place before the end of the waiting period.
	Subsection (6) applies section 95 of the Enterprise Act 2002, which enables statutory restrictions under the merger control regime to be enforced through the courts, to the restrictions on reportable events taking place set out in subsection (1). This for example enables the CMA to apply for an injunction requiring a designated undertaking or group member to undo a reportable event that has taken place prior to the expiry of the waiting period and for the reporting requirements to be complied with before the event takes place again.
