First, the taxpayers argued that the ratio decidendi (the binding reasoning) in Bluecrest was that the exercise of a discretion – here, the discretion to reallocate Special Capital – is a source for the purposes of s687 ITTOIA 2005 only if it creates a legal entitlement to the receipt in question, which the taxpayers said was not the case here.
The Court rejected this argument. Falk LJ carefully reviewed the relevant cases on Schedule D Case VI (the predecessor to s687 ITTOIA 2005) and concluded that neither they nor Bluecrest established that a legal right to payment was required.
Next, the taxpayer argued that GSAM’s discretion to reallocate Special Capital was unfettered and therefore purely voluntary, which again meant that it could not constitute a source.
The Court also rejected this argument, finding that GSAM had an implied duty to exercise its discretion rationally and in good faith. The duty, which is designed to prevent abuse of significant imbalances of power, has been found to exist in the context of employee death-in-service benefits (Braganza v BP Shipping Ltd [2015] UKSC 17), employee bonuses (Horkulak v Cantor Fitzgerald International [2004] EWCA Civ 1287) and allocating LLP profit shares (Reinhard v Ondra LLP [2015] EWHC 26 (Ch)).
The Court accepted the taxpayer’s argument that for a source to exist, something more than this implied duty (but less than a legal right to payment) was required. The critical factor was that the individuals had “rights under the Partnership Deed which provided the legal context for the decisions” to reallocate Special Capital (see [62]). In other words, reallocations were clearly not mere acts of largesse; they were made against a detailed legal and commercial backdrop.
Accordingly, the exercise of the discretion to reallocate Special Capital – subject to the implied duty described above and in the context of the individuals’ rights – was sufficient to constitute a source for the purposes of s687 ITTOIA 2005.
The Court therefore dismissed the taxpayers’ appeals. As in Bluecrest, the Court declined to address the sales of occupation income issue. HMRC reserved the right to argue that GSAM’s profit share belonged to the individuals should the case go to the Supreme Court.
