Blackman v Thompson

This matter concerned an application for special leave to appeal to the High Court of Australia. The applicant, Margaret Napier Blackman, was the original plaintiff and appellant in the Court of Appeal. She was seeking to appeal a decision of the Court of Appeal which had, in effect, dismissed her claim. The respondents included Margaret Elizabeth Thompson, Castle Cove Real Estate Agency, and William Allan Blackman. The dispute centred on the applicant's ability to pursue a claim based on her equitable rights to half of the proceeds of a sale, despite the opposition of the trustee.

The primary legal issue before the High Court was whether the opposition of the trustee to joining in the relief sought by the applicant was fatal to her claim, as determined by the Court of Appeal. The applicant argued that the Court of Appeal erred in holding that she could not rely on her own equitable rights, which were known to the defendants, without the trustee's active participation or consent. A related issue was whether the applicant possessed a valid cause of action in equity to assert and maintain her beneficial interest and seek compensation for breaches, even without the trustee's formal involvement.

The applicant contended that the Court of Appeal's decision was based on an outdated principle requiring a beneficiary to compel a trustee to act or use the trustee's name to pursue a claim. She argued that where a beneficial right is known to all relevant parties, such formalities should not prevent a claimant from asserting their rights. The applicant maintained that her entitlement to half the proceeds of sale was conceded throughout the proceedings, and that she had a recognised, albeit inadequately compensated, right to relief. The Court of Appeal's reliance on the trustee's non-cooperation was submitted to be an error, particularly as the existence of her cause of action was not disputed at earlier stages.
