“Memory is especially unreliable when it comes to recalling past beliefs. Our memories of past beliefs are revised to make them more consistent with our present beliefs… Considerable interference with memory is also introduced in civil litigation by the procedure of preparing for trial… …[So that] “it is important to avoid the fallacy of supposing that, because a witness has confidence in his or her recollection and is honest, evidence based on that recollection provides any reliable guide to the truth.”
“62 Earnings (1) This section explains what is meant by “earnings” in the employment income Parts. (2) In those Parts “earnings”, in relation to an employment, means— (a) any salary, wages or fee, (b) any gratuity or other profit or incidental benefit of any kind obtained by the employee if it is money or money's worth, or (c) anything else that constitutes an emolument of the employment. (3)For the purposes of subsection (2) “money's worth” means something that is— (a) of direct monetary value to the employee, or (b) capable of being converted into money or something of direct monetary value to the employee...”
“Thus the statutory scheme contemplates that all earnings from a person’s employment are taxable, subject only to the allowable deductions provided for by the provisions listed in s.327 (all of which are in Part 5 of ITEPA). The question whether a payment amounts to “taxable earnings” from the taxpayer’s employment is therefore entirely separate from the question whether a deduction is to be allowed against taxable income. Whilst it is only the “net taxable earnings” from a person’s employment which are chargeable to income tax by virtue of s.9(2), the expression “net taxable earnings” is a defined expression which takes into account those types of expenditure which Parliament has expressly stipulated may be deducted.”
“not every payment made by an employer to an employee is necessarily made to him as a profit arising from his employment. Indeed, in my judgment, the authorities show that to be a profit arising from the employment the payment must be made in reference to the services the employee renders by virtue of his office, and it must be something in the nature of a reward for services.”
‘[32] When considering the cause of, or the reason for, an event or an act in a particular case, the courts steer clear of involvement in general theories of causation. Instead they apply a mix of general principle, legal policy and good-sense pragmatism to determine whether legal liability in accordance with the conditions set by the relevant rules has been established on the particular facts of the case … [33] All I need say at this point is that the use of “from” in the idea expressed in the statutory expression “earnings from an employment” and “earnings derived from an employment” in a fiscal context indicates, as matter of plain English usage, that there must, in actual fact, be a relevant connection or a link between the payments to the employees and their employment.’ [86] Mummery LJ also referred at [34] to the fact that appeals are confined to questions of law: ‘[34] … it was for the judge in the FTT, entrusted by statute with the judicial function of finding the facts, to consider all the relevant documents and oral evidence and to make findings of primary fact and proper inferences of fact, to which he then had to apply the tax legislation, as interpreted by the courts. It follows that it is not the task of the UT, or of this court, to re-decide or second guess the primary facts, their proper function being limited to questions of law, such as whether the FTT misinterpreted the law, or misapplied it to the facts, or made perverse findings of fact unsupported by any evidence, or reached a conclusion that was plainly wrong.’ [87] Patten LJ referred (at [50]) to the need for ‘a sufficient causal link to be established between the payment and the employment’
‘[52] It must follow from this that, in order to satisfy the s 9 test, one must be able to say that the payment is from employment rather than from a non-employment source. This has certainly been the approach of the courts in most of the decided cases, examples of which are: (i) Viscount Simonds in Hochstrasser v Mayes at (1959) 38 TC 673 at 706,[1960] AC 376 at 389: “often difficult to draw the line and say on which side of it a particular case falls”; (ii) Lord Wilberforce in Brumby v Milner at[1976] STC 534 at 536,[1976] 1 WLR 1096 at 1099: “not an easy question to answer”; (iii) Lord Diplock in Tyrer v Smart (Inspector of Taxes)[1979] STC 34 at 36,[1979] 1 WLR 113 at 115: “determination of what constitutes his dominant purpose”; and (iv) Carnwath J in Wilcock (Inspector of Taxes) v Eve[1995] STC 18 at 25, 67 TC 223 at 232: where there is more than one operative cause “there is an element of value judgment in deciding on which side of the statutory line the payment falls”. [53] This process of evaluation requires the fact-finding judge to make findings of primary fact based on the evidence as to the reasons and background to the payment and then to apply a judgment as to whether the payment was from the employment rather than from something else …’
