Here's the very latest on the claim by Walter Merricks against MasterCard on behalf of an estimated 46 million consumers - you could be one of them! - which was recently thrown out by the Competition Appeal Tribunal (see http://www.breakinglaw.co.uk/search/label/MasterCard%20claim).
Last Thursday lawyers for Mr Merricks issued an application with the Tribunal for permission to appeal its decision to the Court of Appeal. MasterCard has been given until 8 September 2017 to respond. After that, the permission application may be listed for hearing. There is some legal uncertainty about whether the legal challenge should go to the Court of Appeal or instead be the subject of judicial review to the Administrative Court. My money - though I am not flush with it and things won't change unless you buy my book - is that this claim is going to go to the Court of Appeal via one of the two possible routes. Mr Merricks and his legal team are confident of ultimate success.
