Locus standi and authority to sue distinguished: treatment of threshold questions clarified

23 Apr 2026  |  Author: Charles Sussex, SC, Kerby Lau

The recent decision in Pamela Aldred And Others v. Castle Fiduciary Ltd And Another [2026] HKCFI 2190 offers valuable clarification on a recurring complex issue in trust and commercial litigation: when must a threshold question be determined at the outset, and when can it properly be left to trial? Although both locus standi and authority to sue are threshold questions, the Court made clear that they are not cut from the same cloth—and should not be treated as if they were.

The case arose from a long‑running dispute concerning the Compass Trust. The trustee (one of the defendants) sought to force an early determination of whether the first plaintiff remained a beneficiary after her husband’s death (having previously tried but failed to do so 2.5 years ago). The trustee argued that this standing issue should be tried as a preliminary issue, and that there has been a change in the law since the previous attempt was made, relying heavily on the Court of Appeal’s decision in Bold Shine Investment v Zheng Deli. In Bold Shine, the Court of Appeal emphasised that, contrary to suggestions in some cases, a challenge to a company’s authority to sue “is not a defence” and must be taken at the outset because it concerns whether the action is properly constituted.

But as Cheng J highlighted, Bold Shine deals with authority to sue, not locus standi. The distinction is critical. As the judgment notes, a challenge to authority concerns whether the plaintiff is properly before the court at all, whereas a challenge to standing “is a defence to the substantive cause of action” and may appropriately be determined at trial. The Court expressly recognised that Bold Shine “concerned a plaintiff’s authority to sue, rather than the issue of a plaintiff’s standing,” and that the two concepts should not be conflated. The Court therefore held that Bold Shine did not change the law in any way relevant to the trustee’s position, and described the trustee’s application as “nothing more than an attempt to have a second bite of the cherry,” amounting to an abuse of process.

This clarification matters. It confirms that not all threshold questions demand front‑loading. Where, as here, the plaintiffs’ claims are identical and the other plaintiffs unquestionably have standing, forcing a preliminary trial on one plaintiff’s standing would not advance efficiency or the underlying objectives of case management. Indeed, the Court noted that even if the first plaintiff’s claims were struck out, the remaining plaintiffs’ claims (which were identical) would proceed in any event, making a preliminary issue trial duplicative and wasteful.

The Court awarded indemnity costs against the trustee defendant. The judgment emphasised that the trustee had attempted both to relitigate an issue already decided and to seek leave to appeal “grossly out of time without good explanation.”

For litigators, the decision provides welcome clarity: threshold questions are not monolithic, and attempts to force early determination must be grounded in both principle and practicality.
