The High Court has today found comprehensively in favour of the Competition and Markets Authority (CMA) 바카라 사이트 on all 3 of its grounds 바카라 사이트 after the CMA sought judicial review of certain decisions made by the Competition Appeal Tribunal (CAT) relating to search warrants.
In October 2023, the CMA applied for warrants to search business and domestic premises as part of its investigation into suspected anti-competitive conduct regarding the supply of chemical admixtures for use in the construction industry. The CMA conducted raids to gather evidence as part of its investigation.
While the CAT granted warrants authorising the CMA to search 3 business premises in England and Scotland, it refused the warrant regarding the domestic property. The CAT said it was necessary for the CMA to identify specific evidence demonstrating that an occupier of the property had a 바카라 사이트propensity바카라 사이트 to destroy physical or electronic documents held on their property 바카라 사이트 as their suspected involvement in a secret cartel was not enough.
The CMA was concerned that the CAT바카라 사이트s decision would damage its ability to gather the necessary evidence to effectively investigate and enforce against secret cartels, particularly given the CAT바카라 사이트s indication that the warrants judgment was a guideline case to be followed in the future. As such, the CMA applied to the High Court for judicial review in December 2023.
The High Court agreed with the CMA that the CAT had made an error in its application of the law 바카라 사이트 namely, that it was incorrect to state that specific evidence of a 바카라 사이트propensity바카라 사이트 to destroy electronic or physical documents was always required for a domestic search warrant, and that the CAT바카라 사이트s judgment should not therefore be followed in future cases.
Sarah Cardell, Chief Executive of the CMA, said:
We welcome this important ruling from the High Court, which found comprehensively in our favour on all 3 grounds.
The original judgment by the Competition Appeal Tribunal risked seriously undermining our ability to enforce effectively against illegal cartels.
With the increase in remote-working 바카라 사이트 and electronic communication 바카라 사이트 it바카라 사이트s essential that we are able to search domestic premises to secure evidence of potential breaches of competition law where appropriate to do so.
