Royal Bank of Canada v Commissioners for His Majesty's Revenue and Customs
Factual and Procedural Background
Company B owned 100% of Company C, the licence-holder for a 12.7 % interest in hydrocarbons located in The Field on the United Kingdom continental shelf. Under an internal “Illustrative Agreement,” Company B assumed all economic risks and rewards of exploiting that interest, leaving Company C as a risk-free vehicle that merely held the government licence.
Company B later transferred its entire position to Company A under a Sale and Purchase Agreement (“SPA”). The consideration comprised a lump sum plus ongoing variable payments (the “Payments”).
The United Kingdom tax authority assessed the Payments to United Kingdom tax on the footing that they fell within Article 6(2) of the UK/Canada Double Taxation Convention (“the Convention”) as consideration for the right to work natural resources situated in the United Kingdom.
The First-tier Tribunal upheld the assessment. The Upper Tribunal dismissed Company B’s appeal. The Court of Appeal reversed those decisions, holding that Article 6(2) did not apply. Company A and Company B appealed to the Supreme Court. The majority (led by Judge Rose) dismissed the appeal. Judge Briggs delivered a lone dissent, the substance of which is summarised below.
Legal Issues Presented
- Whether the variable Payments received by Company B constitute “rights to variable … payments as consideration for the working of, or the right to work, … natural resources” under the fifth limb of Article 6(2) of the Convention, so that the United Kingdom has the prior right to tax those Payments.
- Whether, assuming Article 6(2) applies, the Payments are nevertheless chargeable under section 1313 of the relevant domestic legislation (an issue on which the dissent agreed with the majority).
Arguments of the Parties
The opinion does not contain a detailed account of the parties' legal arguments.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Anson v Revenue and Customs Comrs [2015] STC 1777 | Treaties must be construed according to Articles 31–32 of the Vienna Convention, focusing on the objective common intention of the parties. | Used to frame the interpretive approach to the Convention. |
| Collector of Stamp Revenue v Arrowtown Assets Ltd [2003] HKCFA 46 | Purposive construction and a “realistic view” of transactions (derived from the Ramsay line of cases). | Formed the cornerstone of Judge Briggs’s insistence that Article 6(2) be applied to the transaction as it existed in substance, not merely in legal form. |
| Barclays Mercantile Business Finance Ltd v Mawson [2004] UKHL 51; [2005] 1 AC 684 | Confirmation that the purposive/Ramsay approach is a general principle, not confined to tax-avoidance cases. | Relied on to justify applying a purposive construction even though no tax-avoidance motive existed. |
| Rossendale Borough Council v Hurstwood Properties (A) Ltd [2021] UKSC 16; [2022] AC 690 | Modern restatement of the Ramsay doctrine. | Invoked as further authority that purposive interpretation is the norm. |
| McGuckian v Inland Revenue Comrs [1997] 1 WLR 991 | Lord Steyn’s statement that purposive construction “rescued” tax law from insular literalism. | Used to reinforce the proposition that tax provisions—and, by analogy, treaty provisions—must be read purposively. |
Court's Reasoning and Analysis
1. Purpose of Article 6. Judge Briggs reasoned that Article 6 allocates taxing rights over income sufficiently connected to immovable property situated in a Contracting State. The five enumerated limbs of Article 6(2) deliberately enlarge the ordinary domestic concept of “immovable property” so that income streams closely linked to land or natural resources fall within the taxing jurisdiction of the State where those resources are located.
2. Interpretive methodology. Invoking the Vienna Convention, Arrowtown Assets and related cases, the dissent adopted a purposive, realistic approach. This required examining the economic substance of the SPA and the internal arrangements between Company B and Company C, rather than confining the analysis to formal legal rights.
3. Was Company A granted a “right to work” natural resources? By acquiring Company C and the full benefit of the Illustrative Agreement, Company A stepped into Company B’s shoes and obtained the entire economic bundle associated with the 12.7 % licence interest: decision-making power, risk, reward and entitlement to production. Judge Briggs concluded that this amounted to a “right to work” The Field within the meaning of Article 6(2).
4. Character of the Payments. The variable Payments were part of the price Company A agreed to pay for that right. Nothing in Article 6(2) requires the payee to retain a continuing property interest or to be the original grantor of the licence. Nor is the provision limited to grants as opposed to assignments.
5. Rejection of contrary arguments. The dissent dismissed suggestions—accepted by the Court of Appeal and the majority—that unexpressed restrictions should be read into Article 6(2). In Judge Briggs’s view, such constraints would undermine the plain language and purpose of the provision.
6. Conclusion. Because the Payments were consideration for the right to work United Kingdom natural resources, they constituted “immovable property” income under Article 6(2), giving the United Kingdom primary taxing rights. The First-tier and Upper Tribunal decisions should therefore have been restored.
Holding and Implications
Holding: The majority of the Supreme Court dismissed the appeal, leaving the Court of Appeal’s decision intact. Judge Briggs dissented, stating that he would have allowed the appeal and reinstated the First-tier and Upper Tribunal findings in favour of United Kingdom taxation.
Implications: Because the dissent did not carry the day, the governing precedent remains that variable payments of the kind at issue do not fall within Article 6(2) of the Convention. The dissent nevertheless offers a detailed roadmap for a purposive approach that may influence future debates on the scope of “immovable property” and the treatment of income streams linked to natural resources.
