CMA suffers major blow in Supreme Court costs case

25 May 2022

On 25 May 2022, the Supreme Court handed down an important judgment relating to appeals against decisions by public authorities (Pfizer and Flynn v CMA [2022] UKSC 14). There is no generally applicable principle that all public bodies should enjoy protected status as parties to litigation where they lose a case they have brought or defended in the exercise of their public functions in the public interest.
