Procedural Posture

Judicial Review / Final Judgment After Substantive Hearing

  1. 1 Whether HMRC acted unlawfully by failing to mitigate losses of taxpayer clients of Hidenda who submitted Marriage Allowance claims prior to 15 March 2023 using assignment forms deemed valid prior to the policy change
  2. 2 Whether the claim is academic due to HMRC's subsequent actions

Ratio Decidendi

The claim is academic because HMRC has taken steps to mitigate the losses complained of by Hidenda, including processing the relevant claims and undertaking to review any outstanding claims identified by Hidenda; there is no longer a live issue affecting the parties' rights or obligations, and no exceptional circumstances justify continuation of the proceedings.

Application for judicial review dismissed as academic.
