The Competition Appeal Tribunal (CAT) has issued its latest ruling in the mega-claim, Merricks v Mastercard Incorporated & ors.

The Public Bill Committee has opened a call for written evidence on the Digital Markets, Competition and Consumers (DMCC) Bill

‘Both sides are to blame for the situation that has arisen’, the Competition Appeal Tribunal (CAT) has held in a ruling on costs in the multi-billion-pound Merricks v Mastercard claim.

Representatives for Walter Merricks’s £17bn ‘opt-out’ claim against Mastercard have launched the biggest public noticing campaign in legal history.

Mastercard has lost its latest appeal against the Competition Appeals Tribunal (CAT) decision to certify an ‘opt-out’ class action.

Mastercard has been refused permission to appeal the Competition Appeal Tribunal (CAT) judgment greenlighting the claim in the mammoth class action launched by former Financial Ombudsman Walter Merricks.
