"It is not entirely accidental that the Tribunal has not yet ruled on the issue of costs in another regulatory case (the case about Radio Base Station Backhaul Circuits) in which BT was the successful appellant, whereas in this case BT is the losing appellant. It seems to the Tribunal that in some ways there are parallel issues in these two cases which do raise the rather general question of how we should approach the question of costs in this particular regulatory framework. I think in this particular case we have invited submissions on costs by a date in the New Year, but certainly what the Tribunal is wondering, as it were, in the back of its mind, is whether the principles of costs that would apply in orthodox litigation are wholly appropriate to this kind of regulatory litigation which is in a sense an extension of the regulatory system; whether it would not be appropriate in most cases for the various parties – whether regulator or regulated – to support their own costs unless there is some particular reason for deviating from that rule because of the particular circumstances of the case. That is simply a point that the Tribunal has in mind and if the parties in this case would care to bear that in mind when considering the issue of costs in their submissions that, I think, would be helpful to the Tribunal."
"55. – (1) For the purposes of these rules "costs" means costs and expenses recoverable in proceedings before the Supreme Court of England and Wales … (2) The Tribunal may at its discretion, 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 such proportion of the costs as may be just. The Tribunal may assess the sum to be paid pursuant to any order made under paragraph (2) above or may direct that it be assessed by the President or Chairman or dealt with by the detailed assessment of the costs by a costs officer of the Supreme Court …"
"[Rule 26(2)] gives the Tribunal a wide discretion on the question of costs, to be exercised in the particular circumstances of the case. There is no explicit rule before the Tribunal that costs follow the event, but nor is there any rule that costs are payable only when a party has behaved unreasonably. All will depend on the particular circumstances of the case."
