"But thirdly, and to my mind most importantly, the court's ability to make interlocutory costs orders following, in particular, the access to justice reforms in 1998 is a sanction which is available to it in order to encourage responsible litigation. The court marks what it regards as an irresponsible application by an immediate order for the payment of costs. That is intended to bring home to a party, when considering whether to make an application, that an unsuccessful application may carry a price, which will have to be paid at once. If the court is not in a position to enforce immediate interlocutory orders for the payment of costs which it was thought right to make, then the force of that sanction is seriously undermined. It is important that, in cases where the court thinks it right to make an order for immediate payment on an interlocutory application, it does have the power and can exercise the power to ensure that the order is met. For the reasons which Patten J explained, the only effective sanction in a case of this nature is to require payment of interlocutory costs as the price of being allowed to continue to contest the proceedings. Unless the party against whom an order for costs is made is prepared to or can be compelled to comply with that order, the order might just as well not be made."
"For my part, I would hold that, whether or not a statement in such general terms can be supported, the proposition can be supported in a case such as the present where there is no other effective way of ensuring that the interim costs order is satisfied. That, of course, is always subject to what the judge referred to as the overwhelming consideration falling within article 6, that orders requiring payment of costs as a condition of proceeding with litigation are not made in circumstances where to enforce such an order would drive a party from access to justice, but for reasons which the judge explained, and to which I have already referred, this is not such a case."
