" 10 (1) The Tribunal may only make an order in respect of costs (or, in Scotland, expenses)— (a) … (b) if the Tribunal considers that a party or their representative has acted unreasonably in bringing, defending or conducting the proceedings…"
"The appeal will be listed for further argument on the questions whether: (a) HMRC have a discretion whether to cancel registration for gross payment unders. 66 (1) Finance Act 2004 ; and (b) if we conclude that such a discretion exists: (i) whether HMRC failed to exercise any such discretion; (ii) the consequences of a failure to exercise any such discretion; and (iii) the nature of the Tribunal's jurisdiction unders.67(4) Finance Act 2004 to review a determination of HMRC unders.66(1) Finance Act 2004 ."
" This [Rule 10] has echoes of the costs jurisdiction of the former Special Commissioners, contained in reg 21 of theSpecial Commissioners (Jurisdiction and Procedure) Regulations 1994 . But there are crucial differences. First, the power of the Special Commissioners to award costs was confined to a case where a party had acted “wholly unreasonably”. It was not enough that from time to time there had been unreasonableness (see Gamble v Rowe[1998] STC 1247 , per Park J at p 1257). The need for the behaviour to be wholly unreasonable is not included in the 2009 Rules. Secondly, the wholly unreasonable behaviour had to be “in connection with the hearing in question”. The power under the 2009 Rules is wider than this, and does not merely, as was held in Gamble v Rowe , encompass the hearing or preparation for a hearing."
"Parties must (a) help the Tribunal to further the overriding objective; and (b) co-operate with the Tribunal generally."
