For the story so far, see http://www.breakinglaw.co.uk/search/label/MasterCard%20claim
The Court of Appeal has decided that there IS a right of appeal against the dismissal of the claim. But there must now be a further hearing to decide whether Walter Merricks should be given the necessary permission to make that appeal! That further hearing is now set to take place on 05 and 06 February 2019. If permission is granted then the actual appeal will be heard at the same time. If permission is refused then there will be no appeal. Clear as mud, eh?!
