Factual and Procedural Background
The first Appellant ("Company A") is a company incorporated in the British Virgin Islands and owned and controlled by a South African based businessman ("Plaintiff"). Company A is liable to the South African Revenue Service ("Commissioner") for taxes for the 1998, 1999 and 2000 years of assessment totaling approximately Rand 2.6 billion following a final determination of a tax appeal in October 2010. Judgment was entered against Company A on 4 March 2011 in South Africa for these sums.
The Commissioner alleges that upon learning of the investigation, Plaintiff procured the transfer of Company A's assets to the second Appellant ("Company B"), also incorporated in the British Virgin Islands. The Commissioner became aware that approximately 7.8 million was credited to a bank account in London in the name of Company B.
Following the coming into force on 13 October 2011 of a Protocol amending an existing double taxation treaty between the United Kingdom and South Africa, which made provision for mutual assistance in tax collection, the Commissioner requested assistance from the Respondent ("HMRC").
Proceedings were issued in the Chancery Division of the High Court pursuant to that request. HMRC claimed (1) judgment against Company A for the tax debt and (2) relief against Company A and Company B under the Insolvency Act 1986 (transactions defrauding creditors) to make the deposit available for satisfying the tax debt. At the outset, HMRC obtained an order without notice permitting service out of jurisdiction and freezing the deposit pending trial. Company A and Company B applied to set aside that order and to strike out the proceedings, but their application was dismissed by HHJ Pelling QC on 20 July 2012.
The Appellants appeal against that dismissal, limiting their grounds to two issues relating to the temporal scope of the mutual assistance provisions between the United Kingdom and South Africa.
Legal Issues Presented
- Whether Article 25A and Article 27 of the 2002 Double Taxation Convention together permit cross-border collection of tax debts arising from years of assessment commencing prior to the Convention's entry into force.
- Whether the powers conferred by section 173 of the Finance Act 2006 extend to arrangements purportedly applying retrospectively to tax debts arising prior to 19 July 2006, and whether the 2011 Order validly gives effect to Article 25A in respect of such foreign taxes.
Arguments of the Parties
Appellants' Arguments
- The judge erred in holding that Article 25A and Article 27 together permit enforcement of tax debts for years prior to the 2002 Convention's effective date, contending that Article 27 limits the temporal scope of Article 25A to tax debts arising on or after 1 January 2003.
- The judge erred in holding that section 173 of the Finance Act 2006 authorizes arrangements with retrospective effect prior to its commencement on 19 July 2006, contending that the 2011 Order is ineffective insofar as it applies to tax debts arising before that date.
- Submission that Article 25A does not create a new cause of action but rather that its retrospective application alters legal incidents of prior transactions, engaging the presumption against retrospectivity and other linked presumptions.
- Contended that the Memorandum of Understanding relied upon by the Respondent is inadmissible as it is not an agreement between States but between their tax authorities.
- Argued that the temporal limitation in Article 27 should apply to all taxes, including those not expressly listed, by purposive interpretation.
Respondent's Arguments
- Article 25A applies to all revenue claims enforceable under the laws of the requesting State and is not limited by Article 27's temporal provisions.
- Section 173 of the Finance Act 2006 authorizes the making of international tax enforcement arrangements even for liabilities arising before the section came into force.
- The Memorandum of Understanding between the competent authorities of the United Kingdom and South Africa is admissible under the Vienna Convention as an aid to treaty interpretation.
- Enforcement of pre-existing tax liabilities under Article 25A does not involve objectionable retrospective effect or unfairness to taxpayers.
- The Revenue Rule, which previously prevented enforcement of foreign tax claims in the UK, was always liable to abrogation by treaty and does not confer vested rights on taxpayers.

Court's Reasoning and Analysis
The court began by examining the relevant provisions of the 2002 Double Taxation Convention and the 2010 Protocol, focusing on Articles 25A, 27, and VI. It noted that Article 27 sets out the temporal scope of the original Convention, limiting its effect to tax liabilities arising on or after specified dates in 2003. The 2010 Protocol introduced Article 25A, providing for mutual assistance in the collection of taxes, and Article VI, which contains specific provisions on the Protocol’s entry into force and temporal effect.
The court rejected the Appellants' argument that Article 25A must be read subject to the temporal limitations in Article 27, reasoning that such a reading would lead to absurdities, including preventing enforcement of tax debts arising before the 2002 Convention and creating anomalies across different tax types. Instead, the court held that the Protocol’s own entry into force provisions in Article VI govern the temporal scope of Article 25A, limiting its application to requests made after the Protocol came into force.
The court applied established principles of treaty interpretation, emphasizing a purposive approach consistent with the Vienna Convention on the Law of Treaties. It noted that the parties’ intention, as expressed in Article VI of the Protocol, was to allow enforcement of revenue claims regardless of when they arose, so long as the request for assistance was made after the Protocol’s entry into force.
The court also considered the presumption against retrospective legislation and concluded that the application of Article 25A to tax liabilities arising before the Finance Act 2006 or the Protocol’s entry into force does not constitute impermissible retrospective effect. Article 25A does not create new tax liabilities or causes of action but facilitates enforcement of existing debts as if they were domestic claims. The court found no unfairness to taxpayers in this context, as the Revenue Rule preventing enforcement abroad was always subject to abrogation by treaty.
The court further held that section 173 of the Finance Act 2006 validly authorizes arrangements for international tax enforcement, including for liabilities arising before the section’s commencement.
Regarding the Memorandum of Understanding between the competent authorities of the United Kingdom and South Africa, the court found it admissible as an aid to treaty interpretation under the Vienna Convention provisions concerning subsequent agreements and practice.
Finally, the court addressed procedural issues concerning the appellants’ skeleton arguments, emphasizing the importance of concise, well-structured submissions in appellate proceedings.
Holding and Implications
The court’s final decision is to DISMISS THE APPEAL.
Holding: The court upheld the dismissal of the Appellants’ application to set aside the order permitting service out of jurisdiction and freezing the deposit. It ruled that Article 25A of the 2002 Double Taxation Convention, as amended by the 2010 Protocol, applies to tax debts arising before the Protocol’s entry into force, subject only to the limitation that requests for assistance must be made after that date. Furthermore, section 173 of the Finance Act 2006 authorizes the domestic implementation of such arrangements, including for tax debts arising before the Act’s commencement.
Implications: This decision allows the Respondent to enforce foreign tax debts in the United Kingdom under the mutual assistance provisions without temporal limitation based on the accrual date of the tax debts, provided the enforcement requests are made after the Protocol’s entry into force. No new precedent was established beyond the application of existing principles of treaty interpretation and statutory construction. The judgment also highlights the importance of transparency regarding Memoranda of Understanding related to tax treaties and adherence to procedural rules concerning skeleton arguments in appellate courts.
