“Assets” means the Tangible Assets, Sulpetro’s Licence Interests, the Data and the Shares. “Tangible Assets” means the undivided percentage interests whether held legally or beneficially of Sulpetro and Sulpetro (UK) in the plant, equipment, machinery and other physical assets relating to the Licences which percentage interests are more fully described in Appendix B and which assets are more fully described in Appendix C. “Sulpetro’s Licence Interests” means all beneficial rights and interests in the Licences held by Sulpetro; “Data” means all information of whatsoever nature relating to the Licences owned in whole or in part by Sulpetro or Sulpetro (UK); “Shares” means the whole of the issued share capital of Sulpetro (UK); “Licences” means all exploration, appraisal, development or production licences issued by the Secretary of State in respect of both the United Kingdom and the United Kingdom Continental Shelf and currently held by, inter alia, Sulpetro (UK) and which are more fully described in Appendix B; 16. Appendix B to the SPA was headed “Sulpetro UK Holdings” and listed a number of locations, including crucially “Buchan Unit”, extending to 29.7 square kilometers (or 7,339 acres) in which the “Cost interest” and “Working interest” were both 12.706793 (I infer this is a percentage figure, as the “Net area acres” is then given as 933, which is 12.7% of 7,339). The “Expiry Date” was noted as “In Perpetuity”. 17. Appendix C included a list of “Buchan Unit Tangible Assets”, which included eight “production wells”, the Buchan Alpha production platform and various associated equipment. 18. The Consideration for the sale was stated as£16,866,176 in respect of Sulpetro’s Assets (other than the Shares and Sulpetro’s Licence Interests),£250,000 in respect of Sulpetro’s Licence Interests and£10,000 in respect of the Shares, totalling£17,126,176 . In addition, BP was required to pay to Sulpetro on1 March 1988 the sum of£1,873,824 , the amount of an Advance Petroleum Revenue Tax Credit which would be paid or credited to BP as the new operator of the Buchan field, by reference to payments made by Sulpetro before the sale. Normal balancing payments were to be made in respect of cash balances and stocks of oil as at the effective date of the transfer (which was intended to be retrospective to1 November 1986 ) and by reference to subsequent income and expenses between that date and completion of the sale. 19. Finally, clause 5.4 of the SPA provided for a royalty in the following terms: 5.4.1 Subject to Clause 5.4.2, with effect from the Effective Date, BP shall, in respect of each Quarter pay a royalty to Sulpetro in respect of all production from Buchan… For each Quarter, a royalty rate, per barrel in US Dollars, to be applied to actual production from Buchan and Humbly Grove respectively, will be calculated for each field in accordance with the following formula: 50% (A-B) where: ‘A’ is the Actual Market Value (as hereinafter defined) per barrel of Petroleum production from Buchan and Humbly Grove attributable to the interests in those fields acquired by BP pursuant to this Agreement, less Royalty and Production Taxes payable per barrel… ‘B’ is the notional market value per barrel of such Petroleum production in the same Quarter on the basis of a US$20 per barrel selling price less any Royalty and Production Taxes that would be payable on such notional market value. [The clause went on to define “Actual Market Value”, essentially as the “free into pipeline” price at the refinery or tankship, subject to a “floor” of the lowest spot price for comparable oil] 5.4.2 The Royalty Payments contemplated in clause 5.4.1 shall only be made in respect of any Quarter where A is greater than B. The 1986 Novation Agreement 20. Clause 8 of the SPA provided that on Completion, “Sulpetro and BP shall enter into the novation agreements set out in Appendix G”

“… where the construction of an international treaty arises, evidence as to the interpretation of that or subsequent treaties in one of the participating countries forms part of a matrix of material to which reference could properly be made in an appropriate case. As presently advised we would not wish it to be thought that a limited view of the material to which reference could be made in interpreting a double tax treaty should be taken. Had there been some decision of an appropriate Dutch court interpreting a treaty with identical or similar language then, in our view, evidence of such a decision might well have been admissible.”
“If the terms of the definition are ambiguous, the choice of the term to be defined may throw some light on what they mean”, arguing that “were it not for the definition [in s 1313(3)] it would not be suggested that a payment calculated by reference to the production and sale of oil at an oilfield was an ‘exploration or exploitation right’. As a result, it would be wrong to stretch the meaning to cover the royalty interest.”
“subject to the proviso (and to the extent) that the question of deduction of tax is a matter for resolution between the parties, the royalty payments in question are not within the provisions of section 53 ICTA 1970 and are thus not payable under deduction of tax by virtue of the current provisions of the Taxes Acts. It is agreed, following conversations with Mr Thompson of Messrs Freshfields, that the question of Sulpetro’s future liability to UK tax on royalties received under clause 5.4 is to be the subject of further discussions in due course.”
“37. In our judgment, no new information, of fact or law, is required for there to be a discovery. All that is required is that it has newly appeared to an officer, acting honestly and reasonably, that there is an insufficiency in an assessment. That can be for any reason, including a change of view, change of opinion, or correction of an oversight.”
“The requirement for newness does not relate to the reason for the conclusion reached by the officer but to the conclusion itself. If an officer has concluded that a discovery assessment should be issued, but for some reason the assessment is not made within a reasonable period after that conclusion is reached, it might, depending on the circumstances, be the case that the conclusion would lose its essential newness by the time of the actual assessment.” 61. I agree with the UT’s approach in both passages. The requirement for the conclusion to have “newly appeared” is implicit in the statutory language “discover”
