" Categories of earners (1) In this Part of this Act and Parts II to V below— (a) “employed earner” means a person who is gainfully employed in Great Britain either under a contract of service, or in an office (including elective office) with general earnings; and (b) “self-employed earner” means a person who is gainfully employed in Great Britain otherwise than in employed earner's employment (whether or not he is also employed in such employment)."
"(1) Where earnings are paid to an employed earner and in respect of that payment liability arises for primary and secondary Class 1 contributions, the secondary contributor shall (except in prescribed circumstances), as well as being liable for any secondary contribution of his own, be liable in the first instance to pay also the earner's primary contribution or a prescribed part of the earner's primary contribution, on behalf of and to the exclusion of the earner; and for the purposes of this Act and the Administration Act contributions paid by the secondary contributor on behalf of the earner shall be taken to be contributions paid by the earner. (2) . . . (3) A secondary contributor shall be entitled, subject to and in accordance with regulations, to recover from an earner the amount of any primary Class 1 contribution paid or to be paid by him on behalf of the earner; and, subject to sub-paragraphs (3A) to (5) below but notwithstanding any other provision in any enactment], regulations under this sub-paragraph shall provide for recovery to be made by deduction from the earner's earnings, and for it not to be made in any other way."
"Decisions by officers of Board (1) Subject to the provisions of this Part, it shall be for an officer of the Board— (a) to decide whether for the purposes ofParts I to V of the Social Security Contributions and Benefits Act 1992 a person is or was an earner and, if so, the category of earners in which he is or was to be included, (b) …. (c) to decide whether a person is or was liable to pay contributions of any particular class and, if so, the amount that he is or was liable to pay,"
"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 would 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 Ltd v Minister of Social Security[1969] 2 QB 173 ]. 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."
“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.”
"There must be a wage or other remuneration. Otherwise there will be no consideration, and without consideration no contract of any kind. 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 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.”
"There must, in my judgment, be an irreducible minimum of obligation on each side to create a contract of service. I doubt if it can be reduced any lower than in the sentences I have just quoted."
“If there is a relationship between a putative employer and employee, but it is one under which the 'employer' can offer work from time to time on a casual basis, without any obligation to offer the work and without payment for periods when no work is being done, the cases appear to me to establish that there cannot be one continuing contract of employment over the whole period of the relationship, including periods when no work was being done. There may be an 'umbrella contract' in force throughout the whole period, but the umbrella contract is not a single continuing contract of employment. See Clark v Oxfordshire Health Authority[1998] IRLR 125 (Court of Appeal); Carmichael v National Power PLC[1999] 1 WLR 2042 (House of Lords); Stevedoring & Haulage Services Ltd v Fuller[2001] EWCA Civ 651 ,[2001] IRLR 627 (Court of Appeal). That leaves open the possibility that each separate engagement within such an umbrella contract might itself be a free-standing contract of employment, and it was, I believe, that concept which the Special Commissioner had in mind as covering this case. That is consistent with his referring in the same paragraph of his decision to the decision in Market Investigations Ltd v Minister of Social Security[1969] 2 QB 173 ,[1968] 3 All ER 732 , in which part time interviewers for a market research company were held to be engaged under a series of separate contracts of employment. The judgment of Cooke J in that case contains a valuable and much cited discussion of principles which are relevant to distinguishing between contracts of employment and contracts for services rendered in a self-employed capacity (see especially[1969] 2 QB 173 at 184–185,[1968] 3 All ER 732 at 737–738). I confess that I have doubts about the factual conclusion which the learned judge reached when he applied the principles to the facts of the case. For myself, I see considerable force in the alternative analysis, namely that the interviewers provided their services on a freelance or casual basis and not as employees. See for an example of an analysis of that nature O’Kelly v Trusthouse Forte plc[1984] QB 90 ,[1983] IRLR 369 .”
"There was a mutuality of obligation in each engagement namely that the County Council would pay Ms Prater for the work which she, in turn, agreed to do by way of giving tuition to the people for whom the Council wanted her to provide tuition. That is to my mind is sufficient "mutuality of obligation" to render the contract a contract of employment if other appropriate indications of such an employment contract are present."
"As it seems to me the present state of the law is that whether a relationship is an employment or not requires an evaluation of all of the circumstances. In the words of Hart J in Synaptek Ltd v Young[2003] STC 543 , 75 TC 51, para 12, the context is one 'where the answer to be given depends on the relative weight to be given to a number of potentially conflicting indicia' . The presence of a substitution clause is an indicium which points towards self-employment, and if the clause is as far-reaching as the one in Tanton it may be determinative by itself."
"91. Thus, in cases where there is a dispute as to the genuineness of the written terms of a contract relating to work or services, the focus of the enquiry must be to discover the actual legal obligations of the parties. Speaking for myself, I would respectfully suggest that it is not helpful to say that a court or tribunal has to consider whether the words of the written contract represent the “true intention” or the “true expectation” of the parties. There is a danger that a court or tribunal might concentrate too much on what were the private intentions or expectations of the parties. What the parties privately intended or expected (either before or after the contract was agreed) may be evidence of what, objectively discerned, was actually agreed between the parties: see Lord Hoffmann's speech in the Chartbrook case at [64] to [65]. But ultimately what matters is only what was agreed, either as set out in the written terms or, if it is alleged those terms are not accurate, what is proved to be their actual agreement at the time the contract was concluded. I accept, of course, that the agreement may not be express; it may be implied. But the court or tribunal's task is still to ascertain what was agreed. 92. I respectfully agree with the view, emphasised by both Smith and Sedley LJJ, that the circumstances in which contracts relating to work or services are concluded are often very different from those in which commercial contracts between parties of equal bargaining power are agreed. I accept that, frequently, organisations which are offering work or requiring services to be provided by individuals are in a position to dictate the written terms which the other party has to accept. In practice, in this area of law, it may be more common for a court of tribunal to have to investigate allegations that the written contract does not represent the actual terms agreed and the court or tribunal must be realistic and worldly wise when it does so …"
"(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."
"Having dealt at some length with the issues of substitution and control, I can now deal more briefly with the two remaining grounds of appeal. The main reason for this, so far as intention is concerned, is that 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 ([1968] 2 QB 497 at 513) and Massey v Crown Life Insurance Co[1978] 2 All ER 576 ,[1978] 1 WLR 676 . In the majority of cases, however, such statements will be of little, if any, assistance in characterising the relationship between the parties."
