“In a nutshell, the appellant argues that on22 September 2004 SSS transferred its seafood business to Messrs Thomas. Then, on the same day, Messrs Thomas are said by the appellant to have transferred the seafood business to the appellant for consideration equal to market value – the agreement being evidenced, according to the appellant's evidence, by a minute of agreement dated22 September 2004 ”
“233. In the light of my conclusion that the appellant did not purchase goodwill from Messrs Thomas on22 September 2004 or at any other time, it is not strictly necessary to consider the evidence in relation to the market value of goodwill. Nonetheless, because much time at the hearing was spent considering valuation evidence, I shall summarise my main conclusions below.”
“204. In Crown Estate Commissioners v Dorset County Council[1990] 1 All ER 19 , Millett J (as he then was) stated (at 23): “Res judicata is a special form of estoppel. It gives effect to the policy of the law that the parties to a judicial decision should not afterwards be allowed to relitigate the same question, even though the decision may be wrong. If it is wrong, it must be challenged by way of appeal or not at all. As between themselves, the parties are bound by the decision, and may neither relitigate the same cause of action nor reopen any issue which was an essential part of the decision. These two types of res judicata are nowadays distinguished by calling them “cause of action estoppel” and “issue estoppel” respectively.” [Emphasis added]
"... It cannot be right to bind a party to a finding of fact by a court when there was no need to that party to produce evidence to the contrary in that court". 206. As Phipson On Evidence (17th edition) states at paragraph 43 – 31: "
“Prior to the enactment of theIncome Tax Management Act 1964 (the 1964 Act), the function of the tax commissioners was to make assessments and to hear appeals. It was well established during the period of that regime that they were not deciding a 'lis inter partes' and accordingly their decision in respect of one year's assessment could not create any form of res judicata or issue estoppel in respect of a later year's assessment (see IRC v Sneath[1932] 2 KB 362 , 17 TC 149; Caffoor and others (Trustees of the Abdul Gaffoor Trust) v Comrof Income Tax, Colombo[1961] AC 584 at 598–589 and Spencer Bower and Turner Res Judicata (2nd edn, 1969) pp 260–266). The 1964 Act removed from the commissioners the function of making assessments. I do not think that this changes the position that (for present purposes) their decision on an appeal is not a decision on a 'lis inter partes'. This view accords with that expressed in the text books (see eg Whiteman on Income Tax (3rd edn, 1988) para 30.02 and Phipson on Evidence (14th edn, 1990) para 33.48). Accordingly a determination of an appeal by the commissioners or a s54 agreement cannot any more since 1964 than before 1964 afford scope for application of the doctrine of res judicata or issue estoppel in respect of assessments in succeeding years or additional assessments in the same year.” (see eg Whiteman on Income Tax (3rd edn, 1988) para 30.02 and Phipson on Evidence (14th edn, 1990) para 33.48). Accordingly a determination of an appeal by the commissioners or a s 54 agreement cannot any more since 1964 than before 1964 afford scope for application of the doctrine of res judicata or issue estoppel in respect of assessments in succeeding years or additional assessments in the same year.” “Res judicata is a special form of estoppel.

“ 249. Mr Thomas confirmed that he and his brother would have been prepared to sign employment contracts with a purchaser of the trade and to have entered into any required non-competition covenants. Mr Thomas and his brother had worked in the business for many years. 250. The question, therefore, is whether on22 September 2004 the trade should be valued on the basis that a prudent purchaser would heavily discount the value of the business because there were no contracts of employment and no non-competition covenants binding Messrs Thomas into the business or whether it should be valued on the basis that Messrs Thomas would remain with the business and that employment contracts and non-competition covenants would have been entered into. 251. Mr Taub thought it reasonable to assume that the business should be valued on the latter basis. I agree with him. It seems to me that this method of valuation gives effect to what Hoffman LJ described as the "reality principle" to be derived from Buccleuch. In other words, it must be supposed that Messrs Thomas would take the necessary reasonable steps to sell the trade for the highest price. As regards the caveat in Buccleuch that this must not entail 'undue expenditure of time and effort', it seems to me that entering into employment contracts and non-competition covenants would not have involved undue time and effort, or, indeed, expense.”
