"The tribunal may give any direction to ensure that proceedings are dealt with fairly and justly and, in particular, may – (a) apply any provision in procedural rules which applied to the proceedings before the commencement date [1 April 2009 ]; or (b) disapply any provision of the [2009 Rules]."
"(1) The Tribunal may only make an order in respect of costs… - (a) … (b) if the Tribunal considers that a party or their representative has acted unreasonably in bringing, defending or conducting the proceedings; and (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 written 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 .
"A tribunal may direct that a party or applicant shall pay to the other party to the appeal or application – (a) within such period as it may specify such sum as it may determine on account of the costs of such other party of and incidental to and consequent upon the appeal or application; or (b) the costs of such other party of and incidental to and consequent upon the appeal or application to be assessed…by way of detailed assessment. "
“ Under the transitional provisions to be contained in the [Transfer Order], current proceedings will continue before the new tribunal. In these cases the tribunal will have a wide discretion to determine whether the new Rules of Procedure for the Tax Chamber or any procedural rules that were previously applicable should be applied to the proceedings to ensure fairness. ”
“37. … One policy is to give the taxpayer in a Complex case a choice as to the applicable costs regime, a choice which a taxpayer must make at an early stage of the proceedings. If he does not elect to opt out, the appeal falls, by default, within a costs shifting regime. The tribunal is not, it is to be noted, left with a power, at the end of the proceedings, to decide whether to apply a costs shifting regime or not. So, it seems to me, there is a second policy which is to provide certainty about the applicable costs regime at an early stage of the proceedings. There is, of course, a reason for this second policy apart from merely putting the parties into a position so that they know where they are. If a taxpayer was able to exercise his right of election at a late stage, or even until the result of the appeal was known, he would be able to elect for the regime which he knew was the more favourable to him; this would amount, effectively, to one-way costs shifting which was obviously never intended as I have said in paragraph 7 above. 38. … I rather doubt, therefore, that it can be said that the default regime under the 2009 Rules reflects a policy which goes beyond giving the taxpayer a choice and providing for certainty… ”
“48. … It is an easy question to ask, but almost intractable difficulties are met in answering it. For instance, focusing only on work done and expense incurred, does the appropriate costs regime depend simply on whether more than half the time and effort and expense falls one side of that date or the other? Or is there some other test? It cannot, I suggest, be right to say that the matter is one for the discretion of the tribunal without laying down some principles by which that discretion is to be exercised. ”
“ I agree with Mr Ewart that in most cases the proper time for a party to apply for a costs order is when the proceedings have been determined in its favour. I also agree with him that, in most cases, the proper time for that party, if it is engaged in proceedings to which paragraph 7 applies, to apply for a direction under paragraph 7(3) so that a costs order can be made, is when it can apply for a costs order. Only at that point, when matters have been resolved, is the tribunal in a position to assess whether such a direction is required, in all the circumstances of the proceedings and their determination, to ensure that those proceedings are dealt with fairly and justly. ”
“ the Commissioners have concluded that, as a general rule, they should continue their policy of not seeking costs against unsuccessful appellants; however, they will ask for costs in certain cases so as to provide protection for public funds and the general body of taxpayers. For instance, they will seek costs at those exceptional tribunal hearings of substantial and complex cases where large sums are involved and which are comparable with High Court cases, unless the appeal involves an important point of law requiring clarification. The Commissioners will also consider seeking costs where the appellant has misused the tribunal procedure – for example, in frivolous or vexatious cases, or where the appellant has failed to appear or to be represented at a mutually arranged hearing without sufficient explanation, or where the appellant has first produced at a hearing relevant evidence which ought properly to have been disclosed at an earlier stage and which would have saved public funds had it been produced timeously. ”
