“(1) For the purposes of these rules “costs” means costs and expenses recoverable before the Supreme Court of England and Wales, the Court of Session or the Supreme Court of Northern Ireland. (2) The Tribunal may at its discretion, subject to paragraph (3), at any stage of the proceedings make any order it thinks fit in relation to the payment of costs by one party to another in respect of the whole or part of the proceedings and in determining how much the party is required to pay, the Tribunal may take account of the conduct of all parties in relation to the proceedings. (3) Any party against whom an order for costs is made shall, if the Tribunal so directs, pay to any other party a lump sum by way of costs, or all or such proportion of the costs as may be just. The Tribunal may assess the sum to be paid pursuant to any order under paragraph (2) or may direct that it be assessed by the President, a chairman or the Registrar, or dealt with by the detailed assessment of a costs officer of the Supreme Court or a taxing officer of the Supreme Court of Northern Ireland or by the Auditor of the Court of Session.”
“First, as in all cases, there is no immutable rule as to the appropriate costs order; and how the discretion will be exercised in any case will depend on its particular circumstances, one relevant consideration being whether any award of costs may be perceived as frustrating the objects of the Act. Second, subject to this, the starting point is that a successful appellant who can fairly be identified as a “winner” is entitled to recover his costs. Third, such an appellant will not necessarily be entitled to recover all his costs, and may in particular be deprived of those costs referable to issues on which he has failed, or which were not germane to the Tribunal’s decision, or which involved unnecessary prolixity or duplication, and he may suffer a partial or total disallowance of costs by reason of any unreasonable conduct on his part. Fourth, the OFT is not entitled to any special protection from vulnerability to costs orders in favour of successful appellants save such protection as it may obtain by appropriate case management of the appeal directed at ensuring that the costs of the appeal are kept within proportionate bounds.”
