AI confidence in this short overview: high
This case management decision concerned ten procedural disputes in Mr Hannah’s appeals against HMRC discovery and penalty assessments, primarily whether he could amend his grounds to add a permanent establishment (PE) ground and an EU (Article 63 TFEU) ground, and whether expert evidence on Guernsey law should be permitted. The Tribunal refused the PE amendment for lack of particularity, evidential support and because it would be procedurally unfair and require joinder and extensive further evidence. The Tribunal allowed the EU (Art 63) amendment as properly particularised and supported, ordered revised pleadings and permitted valuation expert reports with directions, but refused/withdrew the Guernsey-law expert application. Time to apply for permission to appeal was shortened to 28 days.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: medium
An application to amend grounds of appeal will be permitted only if the proposed amendment is properly particularised, has a realistic prospect of success supported by evidence, and does not unfairly prejudice the other party or require procedural steps (such as joinder of third parties) that would make it inappropriate on case-management grounds; the Tribunal will not permit it where the amendment would raise new fact‑heavy issues affecting non‑parties without fair notice and appropriate evidence.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The Tribunal observed (non-bindingly) that TMA s 50(6)’s power to reduce an assessment does not justify the Tribunal initiating fact‑heavy issues affecting non‑parties without following proper procedural steps. It also noted that where a party is contractually bound by a foreign decision, the Tribunal may sometimes dispense with foreign‑law expert evidence to interpret the legal effect of that agreement, leaving factual findings from another decision‑maker for the trial judge to assess.
