“ 8. The appellants each lodged notices of appeal with the Tribunal on27 December 2012 . One ground of appeal pursued by each appellant was that the respondents had not demonstrated negligence. 9. On26 April 2013 the Tribunal gave directions for the conduct of the appeals. These were standard directions, which did not include any direction for witness statements. However both parties were required to give listing information including whether or not witnesses were to be called. On10 June 2013 the respondents provided listing information and stated “the respondents do not intend to call any witnesses”. 10. The appeals were listed for hearing by way of a notice dated4 February 2014 informing the parties that the appeals would be heard on29 April 2014 . In early March 2014 the respondents confirmed to the appellants’ representative (EDF Tax) that they were not intending to call witnesses. 11. On27 March 2014 EDF Tax wrote to the Tribunal, copied to the respondents, in the following terms: “We note in particular the fact that HM Revenue & Customs (HMRC) do not propose to adduce any witness evidence … Given the fact that the burden of proof falls squarely on them … we have been advised that the appeal should be summarily allowed as there is no evidence or statement of agreed facts on which HMRC’s case can rest. ” 12. The writer went on to say that the appellants would argue at the hearing that the appeals should be allowed on the basis of lack of evidence from the respondents. This approach was repeated in a letter dated4 April 2014 from EDF Tax to the Tribunal. ”
“ if the Tribunal considers that a party or their representative has acted unreasonably in bringing, defending or conducting the proceedings … ”
“ 15. The condition in rule 10(1)(b) is a threshold condition. It is only if the tribunal considers that a party has acted unreasonably in a relevant respect that the question of the exercise of a discretion can arise. 16. A determination of the question whether a party has, or has not, acted unreasonably is, accordingly, not the exercise of a discretion, but a matter of value judgment. ”
