Haworth & Ors v Commissioners for His Majesty's Revenue and Customs
Factual and Procedural Background
At the start of 2000, three family trusts ("the Trusts"), established by two appellants and managed by trustees resident in Jersey, held shares in two companies. A plan was developed to merge these companies and list the new entity on the London Stock Exchange. To avoid capital gains tax ("CGT") on gains from the trusts' shares, tax advisers recommended appointing trustees resident in Mauritius for part of the tax year, followed by UK trustees. Accordingly, Mauritian trustees were appointed mid-2000, the merger and share disposal occurred, and later in the year UK trustees replaced the Mauritian trustees. HM Revenue and Customs ("HMRC") sought to impose CGT on the appellants and the UK trustees for gains from the share disposals. The First-tier Tribunal dismissed the appellants' appeals, a decision affirmed by the Upper Tribunal. The appellants now challenge these decisions in the present appeal.
Legal Issues Presented
- What is the correct interpretation of "place of effective management" ("POEM") as used in the UK-Mauritius Double Taxation Treaty for determining tax residence of the trusts?
- Whether the POEM of the trusts was in Mauritius or the United Kingdom during the relevant period for the purposes of capital gains tax liability.
Arguments of the Parties
Appellants' Arguments
- POEM should be determined similarly to "central management and control" ("CMC"), identifying the place where binding decisions are made by the authorised decision-making body (the trustees), unless that function was usurped or decisions dictated by outsiders.
- The POEM of the trusts is where the trustees made relevant decisions, and the tribunal erred by not applying this test.
Respondent's Arguments (HMRC)
- The First-tier Tribunal applied the correct legal test for POEM based on binding authority from the Court of Appeal in Smallwood v Revenue and Customs Commissioners.
- The approach equating POEM with CMC, as argued by the appellants, is not applicable to the Treaty context.
- There is no challenge to the factual findings of the tribunal, so the appeal should be dismissed.

Court's Reasoning and Analysis
The court examined the meaning of "place of effective management" (POEM) within the UK-Mauritius Double Taxation Treaty, emphasizing that POEM has an autonomous, international meaning distinct from domestic concepts such as central management and control (CMC).
The court noted that the Treaty and the OECD Model Convention treat POEM as a tie-breaker to resolve dual residence, requiring a single effective place of management at any time. In contrast, CMC may yield multiple locations and is primarily a domestic test for company residence, making it unsuitable for POEM's purpose.
The court reviewed relevant case law, including Smallwood and Wood v Holden, concluding that while CMC focuses on where constitutional organs make decisions, POEM requires identifying where realistic, positive, effective management occurs, considering the broader factual context.
Applying these principles, the court accepted the First-tier Tribunal's findings that the Trusts' POEM was in the United Kingdom during the relevant period. This was due to the appellants and their UK advisors orchestrating and superintending the tax planning scheme from the UK, with the Mauritian trustees acting in accordance with a pre-determined plan, performing only day-to-day administrative functions.
The court rejected the appellants' argument that POEM should be equated with CMC and that the trustees' decision-making location alone determined POEM. It held that POEM can be located elsewhere if the effective management and control of the trust's affairs reside outside the trustees' jurisdiction, particularly where trustees act pursuant to a plan devised and controlled by others.
The court also considered treaty interpretation principles under the Vienna Convention and relevant authorities, emphasizing an international and objective approach focusing on the treaty's text, context, and purpose. It found no compelling reason to depart from the established interpretation that POEM is a distinct concept from CMC.
Holding and Implications
The court's final decision is to DISMISS THE APPEAL.
This ruling affirms the approach that the "place of effective management" in the context of the UK-Mauritius Double Taxation Treaty should be determined by where realistic, positive management occurs, not solely by the formal locus of decision-making bodies or trustees. The decision confirms that tax planning arrangements involving temporary appointment of trustees in another jurisdiction will not necessarily shift the POEM if effective control remains elsewhere.
No new precedent was established beyond affirming the applicability of the Smallwood approach to POEM and rejecting the appellants' proposed alignment of POEM with the concept of central management and control.
