25 April 2024: Updated rules published

The revised rules take effect on 25 April 2024 and will apply to all cases where the Phase 1 investigation formally commences after 25 April 2024 (including under sections 22, 33, 44 and 61 of the Enterprise Act 2002) and which is subsequently referred to Phase 2 (a reference is made to the chair of the CMA for the constitution of a group under Schedule 4 to the Enterprise and Regulatory Reform Act 2013). For all cases that are ongoing on 25 April 2024 (where the relevant Phase 1 investigation was formally commenced prior to 25 April 2024), the 2014 rules will continue to apply.

These rules have been revised to reflect changes to the phase 2 merger process.
