(1) Subject to rule 42.27, the court may not, in the exercise of its powers and discretions under section 98 of the Civil Procedure Act 2005, make any order for costs against a person who is not a party.
(2) This rule does not limit the power of the court:
…
(c) to make an order for payment, by a person who has committed contempt of court or an abuse of process of the court, of the whole or any part of the costs of a party to proceedings occasioned by the contempt or abuse of process".
59 The effect of this rule, and its precursor in Pt 52A r 4(3) Supreme Court Rules 1970, is to abolish the traditional categories of jurisdiction to order costs against non-parties discussed in Knight v FP Special Assets Ltd [1992] HCA 28, 174 CLR 178. Because UCPR 42.3 was still in force when Norton (above at [53]) was decided, it was necessary in that case to join the non-party as a party before a costs order could be made against him. Consequently, Norton did not address the traditional jurisdiction to order costs against non-parties.
60 The repeal of UCPR r 42.3 had the effect of overturning an earlier decision of the High Court that the Supreme Court had no power to order costs against a non-party litigation funder which, for a contingency fee, had funded an impecunious plaintiff without providing the plaintiff with an indemnity for adverse costs orders. That was because the litigation funder had not committed "an abuse of process of the court" and thus the application of r 42.3(2)(c) was not attracted: Jeffery & Katauskas Pty Ltd v SST Consulting Pty Ltd [2009] HCA 43, 239 CLR 75.
61 In consequence of the repeal of r 42.3, there is again jurisdiction to order costs against a non-party and the principles discussed in Knight are revived. In Knight costs orders were made against receivers and managers of two insolvent companies that had been involved in litigation with the respondents even though the receivers and managers were not parties to the proceedings because they were responsible for initiating, and were the real parties to, the litigation. Mason CJ and Deane J held:
"The cases awarding costs against non-parties are more readily explicable on the footing that there was no absence of jurisdiction to order costs against non-parties in the strict sense and that the jurisdiction could be exercised against persons who were considered to be the "real parties" to the litigation": at 188.
