“(1) A protective costs order may be made at any stage of the proceedings, on such conditions as the court thinks fit, provided that the court is satisfied that: (i) the issues raised are of general public importance; (ii) the public interest requires that those issues should be resolved; (iii) the applicant has no private interest in the outcome of the case; (iv) having regard to the financial resources of the applicant and the respondent(s) and to the amount of costs that are likely to be involved, it is fair and just to make the order; and (v) if the order is not made the applicant will probably discontinue the proceedings and will be acting reasonably in so doing. (2) If those acting for the applicant are doing so pro bono this will be likely to enhance the merits of the application for a PCO. (3) It is for the court, in its discretion, to decide whether it is fair and just to make the order in the light of the considerations set out above.”
“The essential characteristics of a public law challenge are that it raises public law issues which are of general importance, where the applicant has no private interest in the outcome of the case. It is obvious that many, indeed most judicial review challenges, do not fall into the category of public interest challenges so defined. This is because, even if they do raise issues of general importance, they are cases in which the applicant is seeking to protect some private interest of his or her own.”
“39. On a strict view, it could be said, Goodson remains binding authority in this court as to the application of the private interest requirement. It has not been expressly overruled in this court. However, it is impossible in our view to ignore the criticisms of this narrow approach referred to above, and their implicit endorsement by this court in the last two cases [Compton and Buglife]. Although they were directly concerned with other aspects of the Corner House guidelines, the “flexible” approach which they approved seems to us intended to be of general application. Their specific adoption of Lloyd Jones J's [in Bullmore] treatment of the private interest element makes it impossible in our view to regard that element of the guidelines as an exception to their general approach.”
“Thus, in the only case in this court since Corner House in which the point has been critical, the private interest requirement, as stated in Corner House, has been applied strictly, but in several other cases since then, in none of which has the point arisen for decision, the court has shown a distaste for that strict approach.”
“[t]he other aspect of Corner House that requires attention is that it is confined to public law litigation”
“… it would be stating the principal too high to say that a PCO cannot be awarded in circumstances where private interests are engaged; the jurisdiction is a flexible one and there is no absolute bar but it is right to say that where private interests are engaged that is a significant factor which will bear on the question whether a PCO should be granted or not.”
“But for the decision in Eweida that a PCO cannot be made in private litigation, I would have been minded to make a PCO in this case. It may be that notwithstanding Eweida the wide discretion of the court in matters relating to costs would admit of the possibility of a freestanding order analogous to a PCO, even in private litigation. But it is not necessary for us to go that far. In this case it is open to us to vary the grant of permission to appeal … so as to impose a condition that the appellant, if successful, will not seek costs against the respondents.”
