“The starting point is an ordinary appeal before the [Tribunal]. Here, however unacceptable the idea may be to the ordinary member of the public, it has been clear law binding on this court for sixty years that an inspector of taxes has only to raise an assessment to impose on the taxpayer the burden of proving that it is wrong: Haythornthwaite & Sons Ltd v Kelly ( Inspector of Taxes ) (1927) 11 TC 657 .”
“I must now consider what is meant by a contract of service. A contract of service exists if the following three conditions are fulfilled: (i) the servant agrees that in consideration of a wage or other remuneration he will provide his own work and skill in the performance of some service for his master. (ii) He agrees, expressly or impliedly, that in the performance of that service he will be subject to the other’s control in a sufficient degree to make that other master. (iii) The other provisions of the contract are consistent with its being a contract of service.”
"The servant must be obliged to provide his own work and skill. Freedom to do a job either by one's own hands, or by another's is inconsistent with a contract of service, though a limited or occasional power of delegation may not be ..."
"Control includes a part of deciding the thing to be done, the way in which it shall be done, the means to be employed in doing it, the time when, and the place when it shall be done. All these aspects of control must be considered in deciding whether the right exists in a sufficient degree to make one party the master and the other his servant. The right need not be unrestricted."
“…control will no doubt always have to be considered, although it can no longer be regarded as the sole determining factor'. The fundamental question which has to be asked is whether the person who has engaged himself to perform the services in question is performing them as a person in business on his own account. If the answer to that question is 'yes', then the contract is a contract for services. If the answer is 'no', then the contract is a contract of service.”
"(1) The tribunal should establish what were the terms of the agreement between the parties. That is a question of fact. (2) The tribunal should then consider whether any of the terms of the contract are inherently inconsistent with the existence of a contract of employment. That is plainly a question of law, and although this court, as indeed the appeal tribunal before us, has no power to interfere with findings of fact (an appeal only lies on a point of law), if there were a term of the contract inherently inconsistent with a contract of employment and that has not been recognised by the tribunal's chairman, that would be a point of law on which this court, like the appeal tribunal before us, would be entitled to interfere with the conclusion of the chairman. (3) If there are no such inherently inconsistent terms the tribunal should determine whether the contract is a contract of service or a contract for services, having regard to all the terms. That is a mixed question of law and fact."
"… statements by the parties disavowing any intention to create a relationship of employment cannot prevail over the true legal effect of the agreement between them. It is true that in a borderline case a statement of the parties' intention may be taken into account and may help to tip the balance one way or the other: see Ready Mixed Concrete at 513B and Massey v Crown Life Insurance Co[1978] 1 WLR 676 (CA). In the majority of cases, however, such statements will be of little, if any, assistance in characterising the relationship between the parties."
"In order to decide whether a person carries on business on his own account, it is necessary to consider many different aspects of that person's work activity. This is not a mechanical exercise of running through items on the checklist to see whether they are present in, or absent from, a given situation. The object of the exercise is to paint a picture from the accumulation of detail. The overall effect can only be appreciated by standing back from the detailed picture which has been painted, by viewing it from a distance and by making an informed, considered, qualitative appreciation of the whole. It is a matter of evaluation of the overall effect of the detail, which is not necessarily the same as the sum of the individual details. Not all details are of equal weight or importance in any given situation. The details may also vary in importance from one situation to another."
"Mr Goldsmith invited us to adopt the same approach as that of Lord Griffiths in applying the test or indicia set out by Cooke J [in Market Investigations ]. That is an invitation which I view with some reserve. In cases of this sort there is no single path to a correct decision. An approach which suits the facts and arguments of one case may be unhelpful in another."
"It is in my judgment, quite impossible in the field where a very large number of factors have to be weighed to gain any real assistance by looking at the facts of another case and comparing them one by one to see what facts are in common, what are different and what particular weight is given by another tribunal to the common facts. The facts as a whole must be looked at, and what may be compelling in one case in the light of all the facts may not be compelling in the context of another case."
"(b) where the person is not a party, make provision for the person's necessary expenses of attendance to be paid and state who is to pay them."
