Part 1: Digital Markets Final offer mechanism Section 44: Duration and revocation of final offer orders
This section sets out when a final offer order comes into effect (subsection (1)) and the circumstances in which it ceases to have effect (subsection (2)). Subsection (3) also gives power to the CMA to revoke a final offer order when the CMA has reasonable grounds to believe there has been a material change in circumstances. Where collective submissions have been made, the CMA can also partially revoke a final offer order, e.g. revoke it in respect of some of the grouped third parties, but not others. A material change in circumstances includes, but is not limited to, the third party (or some of the grouped or joined third parties) coming to their own agreement with the designated undertaking in relation to payment terms (see section 43(2)). The CMA has power to make transitional, transitory or saving provisions in relation to revocation (or partial revocation) of a final offer order (subsection (6)).
	The CMA must give a notice to the parties of the decision (including reasons) and publish a summary statement (subsections (4), (5) and (7)).
	Subsection (8) allows the CMA to exercise its functions in relation to potential and actual breaches of a final offer order where the order is no longer in place. This enables the CMA to take action against historic breaches.
