"excerpt": "The Upper Tribunal considered how capital allowance balancing charges apply where an oil pipeline is hived down intra-group and the transferee's activities split into oil-related (ring fence) and non-oil-related trades. The Tribunal allowed the taxpayer's appeal, set aside the FTT decision, and remade it applying its own analysis of the transfer of trade and pooling provisions.",
"judgment_summary": "This appeal concerned the correct amount of a balancing charge arising under the capital allowances regime following a two-stage disposal of an interest in the CATS North Sea pipeline. Amoco (U.K.) Exploration Company, LLC hived down its interest in the pipeline to its wholly owned subsidiary, CNSL, for US$1, and subsequently sold the shares in CNSL to a third party, Kellas (para 2, 36).\n\nThe dispute centred on whether the intra-group transfer of trade provisions in Chapter 1 of Part 22 CTA 2010 applied to the hive-down, given the ring-fence provisions in Part 8 CTA 2010 (particularly section 279, which treats oil-related activities as a separate trade) (para 2-3, 57-58).\n\nThe FTT had held that Part 22 applied and that CNSL's subsequent mixed use of the pipeline triggered a balancing charge of £169,197,035 (para 3, 50). CNSL appealed, arguing the FTT erred in law both as to the application of Part 22 and as to its effect, and raised further dependent issues on pooling of qualifying expenditure (para 4, 52-53).\n\nThe Upper Tribunal allowed the appeal, holding that section 279 CTA 2010 must be taken into account when determining whether Part 22 applies, and that the FTT had erred in holding otherwise (para 94, 146). Applying its own analysis (termed 'Scenario D'), the Tribunal held that Part 22 applied to the part of Amoco's trade concerning transportation of BP group hydrocaratures (Part Y1, IRF to IRF) but not to the part concerning transportation of non-BP hydrocarbons (Part Y2, IRF in Amoco's hands but ORF in CNSL's hands), because Amoco's deemed participator status meant the same trade was not carried on by CNSL in respect of Part Y2 (para 132-140).\n\nThe Tribunal also determined, obiter in view of its conclusion on Part 22, the correct approach to pooling qualifying expenditure, preferring CNSL's approach of upfront apportionment between qualifying activities over HMRC's approach of allocating the full expenditure to each single-asset pool (para 188).\n\nThe Tribunal set aside the FTT decision and remade it in accordance with its own analysis (para 149-150, 190)."

"background": "CNSL was incorporated on 6 October 2014 as a wholly owned subsidiary of Amoco, part of the BP group, and was dormant until 1 October 2015 (para 33). The CATS Pipeline transported hydrocarbons from the Everest/Lomond fields in the North Sea, with BP first incurring capital expenditure on it in 1990 and throughput beginning in May 1993 (para 34). Immediately prior to the hive-down, Amoco held a c36.2% interest in the pipeline (para 34).\n\nIn July 2014, Antin (via Kellas) offered to buy Amoco's interest in the CATS Pipeline (para 35). The disposal occurred in two stages: a hive-down of Amoco's interest to CNSL for US$1 under an agreement dated 18 November 2014, completing on 1 October 2015; and a share sale of CNSL's shares to Kellas for approximately US$388 million on 17 December 2015 (para 36).\n\nBefore the hive-down, Amoco treated all CATS Pipeline activities as part of a single ring fence (IRF) trade, claiming capital allowances at IRF rates on qualifying expenditure of £167,467,319.35 (para 39). After the hive-down, CNSL was not itself a participator in the Everest field but was associated with Amoco, a deemed participator; this meant CNSL's transportation of BP group hydrocarbons remained IRF, while its transportation of non-BP hydrocarbons was ORF (para 40-42).\n\nAt hive-down, CNSL anticipated 13.55% of future tariff income would be IRF and 86.45% ORF; actual figures were 11% IRF and 89% ORF (para 43). After the share sale, CNSL's activities became entirely ORF (para 44). Amoco filed on the basis of a wholly IRF trade; CNSL filed on the basis of mixed IRF/ORF trades and returned an IRF balancing charge of approximately £23m on cessation of its IRF trade at the share sale (para 45).\n\nFollowing an enquiry, HMRC issued a closure notice on 30 March 2021 for CNSL's accounting period ended 31 December 2015, concluding a balancing charge of £169,197,035 arose on the hive-down (or alternatively £166,094,888 if Part 22 did not apply). CNSL appealed against the closure notice (para 46).",
"core_dispute": "The central issue was whether Part 22 CTA 2010 (transfer of trade provisions) applied to the hive-down of the CATS Pipeline interest from Amoco to CNSL, and how the ring-fence deeming in section 279 CTA 2010 (treating oil-related activities as a separate trade) interacted with that question (para 2, 57-58).\n\nCNSL's primary case was that section 279 meant CNSL, after the hive-down, carried on two distinct trades (IRF and ORF), so it could not be said to carry on Amoco's single, wholly IRF trade; Part 22 therefore did not apply, and the normal disposal rules produced a much lower balancing charge (para 58, 54(1)(a)).\n\nHMRC's primary case was that section 279's deeming was confined to computing ring-fence profits and did not affect whether a transfer of trade occurred under Part 22, which focused on the activities transferred rather than their tax classification; on this basis Part 22 applied and a balancing charge of £169,197,035 arose (para 59, 54(1)(b)).\n\nDependent on resolution of the Part 22 issue, further issues arose as to the correct method of pooling qualifying expenditure between IRF and ORF single asset pools, including the scope of sections 53, 206 and 207 Capital Allowances Act 2001 (para 53).",
"court_findings": "The Upper Tribunal held that section 279 CTA 2010 is not confined to computing ring-fence profits but affects the operation of Part 22, so it must be taken into account when determining whether a transfer of trade has occurred (para 71-76, 94). The FTT erred in law by concluding that section 279 did not prevent Part 22 from applying (para 146).\n\nApplying the three-step analysis derived from section 951(3) and Millett J's reasoning in Falmer Jeans Ltd v Rodin [1990] STC 270 (Ch), the Tribunal held that identity of activities alone is insufficient; it is also necessary to ask whether the same trade would have been transferred had the relevant part been carried on separately by the transferor (para 116-121, 132-133).\n\nThe Tribunal rejected both HMRC's case that Part 22 applied in full and CNSL's primary case that Part 22 did not apply at all, instead adopting "Scenario D": Amoco's trade is treated as divisible into two part trades, Part Y1 (transportation of BP group hydrocarbons, IRF to IRF) and Part Y2 (transportation of non-BP hydrocarbons, IRF in Amoco but ORF in CNSL). Part 22 applied to Part Y1 but not to Part Y2, because CNSL, lacking Amoco's deemed participator status, was not carrying on the same trade as Amoco in respect of Part Y2 (para 132-140).\n\nOn the pooling issue, obiter given the outcome above, the Tribunal preferred CNSL's construction: section 53(2) CAA 2001 prohibits allocating expenditure relating to two qualifying activities in full to both pools, requiring upfront apportionment; and sections 206-207 CAA 2001 address only mixed qualifying/non-qualifying use, not use across two qualifying activities (para 167-188). The Tribunal disagreed with the FTT's contrary obiter views on pooling (para 188).",
"outcome": "The Upper Tribunal allowed CNSL's appeal, set aside the FTT Decision, and remade the decision in accordance with its own analysis under 'Scenario D' (para 149-150, 190).\n\nOn Part Y1 (IRF to IRF), Part 22 applies on the hive-down, so section 948(3) CTA 2010 prevents any balancing allowance or charge at that point; on the share sale, a section 61(1)(f) disposal event arises in CNSL, producing an IRF balancing charge of approximately £23 million (para 152-155, 160).\n\nOn Part Y2 (IRF to ORF), Part 22 does not apply on the hive-down, so the hive-down is a section 61(1)(a) disposal event in Amoco, producing an Amoco balancing charge of approximately £2 million (subject to a dispute, of limited materiality, as to apportionment of the US$1 consideration) (para 156-157). No further disposal event arises for Part Y2 in CNSL on the share sale (para 158).\n\nThe Tribunal did not remit the matter to the FTT, exercising its discretion to remake the decision itself given the parties' full submissions (para 149).",

"uncertainties": "The judgment does not specify a formal reported citation beyond the neutral citation given; the FTT decision reference [2024] UKFTT 00512 is noted but not further detailed. Some figures (e.g. the '6 pence' difference and precise TWDV figures) are described as de minimis or illustrative rather than fully resolved by the Tribunal, and the section 207 'just and reasonable' calculation was left unaddressed given the Tribunal's conclusion on pooling (para 189)."
