Quinn Emanuel Urquhart & Sullivan and Freshfields Bruckhaus Deringer are making the final preparations for next month’s U.K. Supreme Court hearing in the major £14 billion Mastercard saga, which will proceed via videolink.

The case, which is set to play out its final phases in the Supreme Court on May 13, is according to people close to the matter, likely to be a precedent-setting case that will have significant consequences for subsequent civil cases.
