These Rules amend the tribunal procedure rules that apply in the First-tier Tribunal and Upper Tribunal, to expressly provide that the power to set-aside a decision of a tribunal which disposes of proceedings can be exercised by the First-tier Tribunal and Upper Tribunal, either on the application of a party or on the tribunals’ own initiative. These amendments are made to clarify the tribunals’ power to set-aside, following the decision of the Upper Tribunal in MA v Secretary of State for Work and Pensions [2020] UKUT 172 (AAC).
