In a key test case on the relevance of tax losses (and more broadly, HMRC) under Part 26A of the Companies Act 2006, Mr Justice Michael Green in the High Court has sanctioned the second restructuring plan (RP2) of Waldorf Production UK Plc (the Plan Company), overriding HMRC’s challenge by using the cross-class cram down power in s.901G. The judgment resolves, at least at first instance, a series of live questions about the limits of HMRC’s ability to challenge restructuring plans and the proper scope of the “no worse off” test.
