Short overview

This short overview is intended to summarise the case, issues and outcome so far as they are supported by the judgment.

AI confidence in this short overview: high

This appeal concerned whether HMRC's 11 January 2023 letter was a valid final closure notice and whether the First-tier Tribunal had jurisdiction because a valid notice of appeal had been given to HMRC. The Tribunal held the closure notice was valid but that no valid notice of appeal was given to HMRC: one letter (13 Feb 2023) did not objectively indicate an intention to appeal, and another (25 Feb 2023) though properly worded was not proved to have been received by HMRC; accordingly the Tribunal lacked jurisdiction and struck the appeal out.

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: high

The Tribunal treated compliance with the statutory requirement to give notice of appeal to HMRC as a condition precedent to the Tribunal acquiring jurisdiction. A document only amounts to a valid notice of appeal if, objectively judged by its terms and context, it clearly indicates an intention to appeal a specific HMRC decision. Where service by post is relied on, the presumption of posting may be rebutted by clear and cogent evidence that the addressee did not receive the letter.

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 judgment indicated, without deciding it as a binding point, that lack of formal written authorisation does not inevitably prevent a representative from giving a valid notice of appeal if it is clear to HMRC the representative is acting for the taxpayer. It also remarked that an agreement to stay substantive progress pending related proceedings does not undermine the validity of a closure notice.
