“A contract of service exists if these 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” (at 515). 45. Considering these points, therefore: 46. Mutuality of obligation: the principal submission made by the appellant was that there was no mutuality of obligation between himself and Subsea 7 because Subsea 7 were not obliged to give him work and therefore he could not be considered to be employed as part (i) of the test in Ready Mixed Concrete would not be met. 47. HMRC submitted that there was clear mutuality of obligations as Subsea 7 were obliged to pay the appellant and the appellant was obliged to work at least 150 days per year. 48. I agree with HMRC that both parties had obligations under the contract; the fact that Subsea 7 was able to choose to pay the appellant without making him work did not change that. I find therefore that there is mutuality of obligation during each assignment. 49. Right of substitution : the appellant argued there was no contract for personal service as his spouse provided back office services and so the services were not exclusively provided by him, and that the contract was for team services. HMRC submitted that the appellant was not allowed by Subsea 7 to provide a substitute to undertake activities on his behalf. 50. The principal statement of employment is specifically between Subsea 7 and the appellant. It makes no reference to partnership and was entered into three years before the partnership existed. There was no suggestion, or evidence, that the contract had been novated to the partnership. Subsea 7 stated in correspondence that they would not enter into diving contracts with partnerships. In my view, the contract is clearly personal to the appellant as “the Employee. I consider that there is no scope for interpreting the contract as being one for “team services”. 51. The appellant’s evidence was that his spouse dealt with administration whilst he was away on assignment with Subsea 7 and that she dealt with third party professionals and liaised with customers to find future work for the appellant. 52. In my view, none of these activities relate to the appellant’s engagement by Subsea 7 and so the performance of such activities by the appellant’s spouse cannot be regarded as being in substitution for the appellant in the Subsea 7 contract, even if such substitution was permitted. 53. Control: The appellant did not make particular submissions as to control, and HMRC stated that control was exercised by Subsea 7. 54. The contract between the appellant and Subsea 7 requires the appellant to “carry out such duties … as are issued to you from time to time. The contract also provides that Subsea 7 will direct how the contract working days are to be organised. Failure to comply or to make himself available would be regarded as a serious breach of contract by the appellant, liable to action under disciplinary provisions. 55. Correspondence between Subsea 7 and HMRC states that Subsea 7 consider that divers are under the full direction and control of dive supervisors and the offshore manager, and that they are required to follows Subsea 7 protocols for all activities. Any change from the protocols is subject to a management of change procedure and requires authorisation by Subsea 7. Subsea 7 also confirmed that the divers can be given extra tasks and can be moved from task to task and reassigned if necessary. This was not disputed by the appellant. 56. On the evidence provided, it is clear that it is Subsea 7 who has control over the work undertaken by the appellant. Subsea 7 can, and does, determine the tasks to be undertaken by the appellant and the hours to be worked on any given assignment. 57. Other factors : the appellant is entitled to paid leave and sick pay; the contract is stated to be one of employment. Although that need not be definitive, there is nothing in the contract which is inconsistent with the appellant being an employee of Subsea 7. Conclusion as to employment status 58. I find, therefore, that there was mutuality of obligation in each of the assignments taken on by the appellant; that Subsea 7 had substantial control over the appellant’s work (both as to what work was done and how it was done); and that the other factors raised are not inconsistent with a contract of service. 59. On that basis, the relationship between the appellant and Subsea 7 was one of employment and not a trade capable of being carried on in partnership (or, indeed, as a sole trader). Whether there was a partnership 60. The appellant further argued that, even if he were regarded as employed, the case of Newstead v Frost 53 TC 525 made it clear that a partnership can exist to exploit the earnings of one partner and that the partners do not have to have the same role. The appellant acted as the diver, whilst his spouse provided administration functions. 61. The appellant also noted that, in the case of Valantine[2011] UKFTT 808 , HMRC had argued that limited participation was not a bar to someone being a partner in a partnership. 62. The appellant’s evidence was that he had entered into a partnership with his spouse on6 April 2014 , having previously been a sole trader. Although no partnership document was entered into, it was submitted that the partnership existed because it met the criteria ins1 Partnership Act 1890 : “Partnership is the relation which subsists between persons carrying on a business in common with a view of profit.”s45 of the Partnership Act 1890 states that “The expression “business” includes every trade, occupation, or profession.”
