Coulthard v State of South Australia (Adnyamathanha, Ngadjuri and Wilyakali Overlap Claim)

The case of Coulthard v State of South Australia involved an interlocutory application by Ms Stuart, acting on behalf of the Adnyamathanha, Ngadjuri, and Wilyakali peoples, seeking leave to be heard as an amicus curiae in the native title proceeding. The primary dispute was over the costs associated with this unsuccessful interlocutory application, specifically whether the costs should be borne by the interlocutory applicant and whether the solicitor for the interlocutory applicant should personally bear the costs. The matter was heard in the Federal Court of Australia.

The legal issues before the court were twofold: first, whether the unsuccessful interlocutory applicant should bear the costs of the three applicant groups; and second, whether the solicitor for the interlocutory applicant should be ordered to bear the costs personally, pursuant to section 43(3)(f) of the Federal Court of Australia Act 1976. The court was required to consider the relevant provisions of the Federal Court of Australia Act 1976 and the Federal Court Rules 2011 to determine the appropriate allocation of costs.

In deciding these issues, the court held that the unsuccessful applicant and their solicitor should bear the costs of and incidental to the interlocutory application. The court considered that the unsuccessful application did not have any prospects of success and was an abuse of process, warranting a costs order. Additionally, the court found that the solicitor's conduct in pursuing the application was unreasonable, leading to the imposition of personal costs against the solicitor. The court's decision was based on the principle that parties should not be allowed to abuse the court process and that the costs of such applications should be borne by the unsuccessful party and their representative.

The orders made by the court required Ms Stuart to pay the costs incurred by the First, Second, and Third Applicants in respect of the interlocutory application, on a party/party basis. Furthermore, Mr Campbell, as the solicitor for Ms Stuart, was ordered to pay the costs incurred by the First, Second, and Third Applicants and the First Respondent, also on a party/party basis. The entry of these orders is governed by Rule 39.32 of the Federal Court Rules 2011.
