Value added tax – Personal liability notices. The First-tier Tribunal (Tax Chamber)(the FTT) had erred in failing to acknowledge or give proper force to the position that, as a matter of principle, the need for statutory time limits to be respected was a matter of particular importance to the exercise of its discretion. Accordingly, the Upper Tribunal (Tax and Chancery Chamber) allowed the appeal by the Revenue and Customs Commissioners (HMRC) against the FTT's decision which had allowed the respondent's application for permission to appeal out of time against the personal liability notices (PLNs) imposed on the respondent by HMRC following the insolvency of the company which the respondent had been a director of. The FTT's decision was remade on the basis that in all the circumstances of the case, the respondent had not given a sufficiently good reason for the serious and significant delay in appealing against those PLNs.
