In a brief statement, the group noted that, on 8 July, The First-Tier Tribunal (Tax Chamber) delivered its decision to allow the company's appeal. It added that the decision is subject to a possible further appeal by HMRC to the Upper Tribunal.
If HMRC chooses to make such an appeal, then it must do so within 56 days of the delivery of the First-Tier Tribunal's decision, the group said, while any such appeal must be based on an error of law. The findings of fact made by the First-Tier Tribunal are final, it noted.
The company pointed out that it has fully provided for assessments previously issued by HMRC in its accounts, up to and including its accounts for year ended 31 December 2018.
The group said it will announce further developments as they arise.
