" (1) The costs of and incidental to (a) all proceedings in the First-tier Tribunal, and[...] shall be in the discretion of the Tribunal in which the proceedings take place.(2) The relevant Tribunal shall have full power to determine by whom and to what extent the costs are to be paid.(3) Subsections (1) and (2) have effect subject to Tribunal Procedure Rules."
“ (1) The Tribunal may only make an order for 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; (c) if- (i) the proceedings have been allocated as a Complex case under rule 23 (allocation of cases to categories); and (ii) the taxpayer (or, where more than one party is a taxpayer, one of them) has not sent or delivered a wriiten request to the Tribunal, within 28 days of receiving notice that the case had been allocated as a Complex case, that the proceedings be excluded from potential liability for costs or expenses under this sub-paragraph ; or [ … ] (2) The Tribunal may make an order under paragraph (1) on an application or of its own initiative. (3) A person making an application for an order under paragraph (1) must- (a) send or deliver a written application to the Tribunal and to the person against whom it is proposed that the order be made; and (b) send or deliver with the application a schedule of the costs or expenses in sufficient detail to allow the Tribunal to undertake a summary assessment of such costs or expenses if it decides to do so. [ … ] (6) The amount of costs (or,, in Scotland, expenses) to be paid under an order under paragraph (1) may be ascertained by – (a) summary assessment by the Tribunal; (b) agreement of a specified sum by the paying person and the person entitled to receive the costs or expenses (the “ receiving person ” ); or (c) assessment of the whole or a specified part of the costs or expenses incurred by the receiving person, if not agreed. (7) Following an order for assessment under paragraph (6) (c) the paying person or the receiving person may apply(a) in England and Wales, to a county court, the High Court or the costs office of the Supreme Court (as specified in the order) for a detailed assessment of the costs on a standard basis or, if specified in the order, on the indemnity basis; and the Civil Procedure Rules shall apply, with necessary modifications, to that application and assessment as if the proceedings in the tribunal had been proceedings in a court to which theCivil Procedure Rules 1998 apply;[ … ] ”
“… the tribunal may only make an order in respect of costs “ of and incidental to ” the proceedings. There is no power to make an order in respect of anything else,and particularly, in the context of this case, in respect of the investigation into Mr Catana ’ s tax affairs which proceeded the proceedings. ”
“… one thing that has not changed is that the Tribunal ’ s jurisdiction continues to be limited to considering actions of a party in the course of the “ proceedings ” , that is to say proceedings before the Tribunal whilst it has jurisdiction over the appeal. It is not possible under the 2009 Rules, any more than it was under the Special Commissioners ’ regulations, for a party to rely upon the unreasonable behaviour of the other party prior to the commencement of the appeal, at some earlier stage in the history of the tax affairs of the taxpayer, nor, even if unreasonable behaviour were established for a period over which the Tribunal does have jurisdiction, can costs incurred before that period be ordered. In these respects the principles in Gamble v Rowe, and Carvill v Frost [2005] STC (SCD) 208 remain good law. That is not to say that the behaviour of a party prior to the commencement of proceedings can be entirely disregarded. Such behaviour, or actions, might well inform actions taken during proceedings, as it did in Scott and another (trading as Farthings Steak House v McDonald [1996] STC (SCD) 381, where bad faith in the making of an assessment was relevant to consideration of behaviour in the continued defence of an appeal. ”
“… It follows that so much of Mr Catana ’ s application as respects any costs he incurred before the proceedings before the First-tier Tribunal were brought cannot succeed, irrespective of its underlying merits which, consequently, I shall not explore. ”
“It seems to us that it cannot be that any wrong assertion by a party to an appeal is automatically unreasonable... Before making a wrong assertion constitutes unreasonable conduct in an appeal that party must generally persist in it in the face of an unbeatable argument that he is wrong...”
“... The Tribunal should not be too quick to characterise pursuing what is found to be an unsuccessful case is unreasonable behaviour: the Tribunal rules provide for a no-costs regime in virtually all tax cases (and the exception for complex cases does not apply in this case). So if in this case HMRC’s view had no reasonable prospect of success, HMRC would have been acting unreasonably if they ought to have known this but not otherwise. In considering whether HMRC ought to have known whether the case had a reasonable prospects of success, I consider that I should consider HMRC as a whole and not just the individual officer presenting the case.”
