R (Wang & Anor) v Secretary of State for the Home Department
[2023] UKSC 21 - UK Supreme Court [2021] EWCA Civ 679 - Court of Appeal (Civil Division)
The firm acted for the applicant, Ms Wang, in judicial review proceedings that became a leading authority on the Tier 1 (Investor) Migrant visa route. The case concerned a structured investment scheme operated by Maxwell Asset Management through which over 100 investors - many of them Chinese nationals - sought to satisfy the £1 million investment threshold required under the Immigration Rules.
The central legal question was whether investors who participated in such a scheme had deployed "money of one's own" within the meaning of the Rules, where the scheme's operators pre-determined all investment decisions.
The Court of Appeal overturned the Upper Tribunal's decision and ruled in favour of the investors, holding that the scheme met the requirements of the Rules as then drafted. The Secretary of State appealed to the Supreme Court, which unanimously allowed the appeal and restored the refusal, establishing the important principle that the Immigration Rules must be interpreted with an "unblinkered" approach to the analysis of the underlying facts.
The case was widely reported in the specialist legal press, including coverage by Free Movement, the UKSC Blog, and the Electronic Immigration Network.

HungryPanda AU Pty Ltd & Ors v Yan Liu & Ors
[2025] EWHC 1512 (Comm) - High Court (Commercial Court)
The firm acted for the first and third defendants in this substantial commercial dispute heard in the Commercial Court before Peter MacDonald Eggers KC, sitting as a Deputy Judge of the High Court.
The case arose from an asset purchase agreement under which HungryPanda acquired the Easi online food delivery business across multiple jurisdictions, including Australia, Japan, and New Zealand. Following completion, a dispute arose over alleged breaches of the agreement, including the withholding of critical IT assets and operational disruption that caused significant damage to the acquired business.
The Commercial Court awarded damages of £11.7 million to the claimants. The case is notable for its cross-border dimensions and the complexity of the commercial arrangements involved.

Security Industry Authority v Josoemag Services Ltd & Ors
[2025] EWHC 1381 (KB) - High Court (King's Bench Division)
The firm instructed counsel for the respondents in this appeal before Mr Justice Kerr concerning the intersection of regulatory law and human rights.
The respondents - a security staffing company and its directors - brought a claim against the Security Industry Authority under section 8 of the Human Rights Act 1998, alleging that the SIA had wrongfully interfered with their right to peaceful enjoyment of property contrary to Article 1 of the First Protocol to the European Convention on Human Rights, in the course of its regulatory activities under the Private Security Industry Act 2001.
The case raised important questions about the circumstances in which a statutory regulator's exercise of its powers may engage Convention rights and give rise to a claim for damages.
