Resolution of the issues on the appeal
77 In our view it is unhelpful, as part of the process of statutory construction required by this case, to focus solely on the expression "foreign earnings". What s 23AG(1) exempts from tax are "foreign earnings derived … from … foreign service" which has been engaged in for a continuous period of not less than 91 days. What the expression "foreign earnings" connotes is therefore limited or controlled by the requirement that the earnings be derived from "foreign service". That requirement, in turn, directs attention to the need created by the definition in s 23AG(7), of "foreign service" for the service to be rendered in a foreign country "as the holder of an office or in the capacity of an employee."
78 "Earnings", we accept, has a wider connotation than salaries or wages and includes, as the definition of "foreign earnings" in s 23AG(7) indicates commission, bonuses and allowances all of which are capable of being, and frequently are, derived in the capacity of an employee from an employer. We also incline to think that the presence of the word "earnings" in the definition is sufficient to allow it to comprehend remuneration, like tips or gratuities, received from persons other than the employer provided that it is sufficiently incidental to the employment to permit it to be characterised as having been received in the capacity of an employee. A person who is concededly an employee but derives a fee or other remuneration as an independent contractor pursuant to a contract separate from his or her contract of employment, whether that separate contract is with the conceded employer or some third person, does not derive that fee or other remuneration "in the capacity of an employee".
79 We therefore consider, with respect, that the learned primary Judge was correct in identifying the principal issue to be resolved in this case as being whether the Consultancy and Management Fee of US$1,200,000 had been derived by the appellant in Nigeria in the capacity of an employee.
80 We accept that, in drawing the distinction between a contract of service and a contract for services, the term "consultant" is not to be treated as synonymous with "independent contractor." Not infrequently as a matter of current usage firms of solicitors or accountants or the like hold out, as a "consultant," a person who, on a proper application of the tests discussed below, is concededly an employee of the firm. The fact that the parties to the relevant contract choose to confer on such a person a title or nomenclature like "consultant" is not determinative of the true character of the relationship between them: Roy Morgan Research Centre Pty Ltd v Commissioner of State Revenue (Vic) (supra) at 537 and the cases there cited.
81 However, we do not consider that in the passage quoted at [44] above the learned primary Judge treated the terms "consultant" and "independent contractor" as synonymous. All that his Honour was there saying was that remuneration derived by a consultant or independent contractor howsoever called under a contract antecedently determined to be one "for services" is prima facie comprehended within the phrase "foreign earnings". The question remained in the present case, as his Honour recognised, whether the Consultancy and Management Fee had been derived by the appellant as a party in his personal capacity to a contract with Meisei "of service" or "for services".
82 The authorities canvassed in the respective submissions of the appellant and the Commissioner make it clear that drawing the distinction involves questions of fact or of mixed fact and law. It is not to be undertaken mechanically by checking a list of indicia which decided cases have identified as tending towards or against characterising a person as either an employee or an independent contractor: see Hall (Inspector of Taxes) v Lorimer [1992] 1 WLR 939 at 944 which was cited with approval by Tadgell JA in Green v Victorian Workcover Authority [1997] 1 VR 364 at 375. As the High Court noted in Stevens v Brodribb Sawmilling Co Pty Ltd (supra) at 37, the available indicia do not always point in the same direction and do not always have the same significance. In the present case, this Full Court has had available to it the oral testimony and the documentary evidence which had been received by the learned primary Judge. However, it has not been demonstrated by the appellant that his Honour misapplied any of the tests made available by that material or overlooked some feature of it which should, or could, have proved decisive in characterising the appellant's work in Nigeria before 1 January 1998 as having been undertaken as an employee of Meisei.
83 Minds may obviously differ on the weight or significance to be attached to particular elements of the relationship which are demonstrated by the evidence in a case such as this. Although it may not be essential to the dismissal of the appeal, the members of this Full Court, if deciding the matter afresh after drawing all appropriate and available inferences, would, on balance, have come to the same conclusion as the learned primary Judge.
84 In particular, we agree with his Honour's analysis of the Agreement as reflecting an understanding that the appellant, as the controller of Navarro, was to be the "organic source" or natural person through whom the services, skill and expertise offered by Navarro were to be supplied in consideration of the Consultancy and Management Fee. On that analysis, Navarro had in Nigeria its own "organisation" which was complementary to, but not subsumed by, the larger organisation with its own employees created by Meisei to install the shop building and other facilities on Bonny Island. The same understanding is reflected by the facsimile message from Meisei to Navarro of 8 July 1997 which is reproduced at [54] above. In our view, Meisei was thereby enquiring why the Consultancy and Management Fee was to be paid to the appellant and not to Navarro which was to provide the consultancy and management services. The response of 9 July 1997, suggesting that the appellant was to be "employed by Meisei as a Consultant in Nigeria", was not effective to displace that understanding because it reaffirmed the terms of the Agreement and asserted that the appellant "will be 100% backed by Navarro Chemicals". The legal basis for that backing could only have been that Navarro was to continue as a party principal to the Agreement and to remain vicariously liable for the activities of the appellant otherwise than as Plant Manager under the Employment Contract after the plant had been commissioned.
85 The fact that the parties found it necessary to create two distinct contractual documents indicates that the relationships to be created by those documents were perceived as different. That does not entail that the Agreement was incapable of creating a relationship of employer and employee between Meisei and the appellant. However, the existence of a parallel contract which is concededly one of service by the employees which it covered invites the closest scrutiny to be given to the Agreement before concluding that it also obliged the appellant, otherwise than as Plant Manager, to serve Meisei as its employee.
86 The size and mode of payment of the Consultancy and Management Fee is an important point of distinction in this regard. In Ronpibon Tin NL v Federal Commissioner of Taxation (supra) it was held that the size of management and directors' fees was irrelevant to the question of whether those expenses had been incurred in earning assessable income. As the Full High Court said, at 60;
'It is important not to confuse the question how much of the actual expenditure of the taxpayer is attributable to the gaining of assessable income with the question how much would a prudent investor have expended in gaining the assessable income. The actual expenditure in gaining the assessable income, if and when ascertained, must be accepted. The problem is to ascertain it by an apportionment. It is not for the Court or the commissioner to say how much a taxpayer ought to spend in obtaining his income, but only how much he has spent: see per Ferguson J. in Tooheys Ltd. v. Commissioner of Taxation [(1922) 22 SR (NSW) 432], at p. 440; per Williams J. in Tweddle v. Federal Commissioner of Taxation [(1942) 7 ATD 186], at p. 190. The question of fact is therefore to make a fair appointment to each object of the companies' actual expenditure where items are not in themselves referable to one object or the other.'
87 It may be acknowledged that a comparatively very high salary paid to a worker with specialised or exceptional skills, particularly one required to work in an onerous or uncongenial location, does not, of itself, detract from his or her being an employee. However, where, as here, high remuneration is payable in a small number of large instalments not specifically referable to the amount of work performed or the time spent in performing it, the inference is more readily available that it was to be paid for the achievement by the recipient of a particular result rather than for his or her contribution as an employee to the achievement of that result by the putative employer: World Book Pty Ltd v Federal Commissioner of Taxation (supra) at 415 and 419-420. We are reinforced in drawing that inference by the fact that instalments of the Consultancy and Management Fee were paid against invoices rendered by Navarro, whereas the admitted salary or wages at the rate of US$100 an hour were paid to the appellant as Plant Manager against time sheets completed by him like an ordinary employee. Likewise, the obligation to pay the Consultancy and Management Fee even if work were stopped by force majeure argues strongly that it was payable in consideration of a promise given as an independent contractor.
88 We do not regard as significant the fact that, to comply with Nigerian regulations governing the presence of foreign workers and the taxation of income which they derived, the appellant had been issued with a badge or name tag designating him as an employee of Meisei's Nigerian associate, Marubeni Engineering West Africa Ltd and was correspondingly notified in that way to the Nigerian tax authorities. The treatment of the appellant in that way for Nigerian tax purposes is at least cancelled out, for the purposes of the characterisation, by the appellant's failure to return any part of the Consultancy and Management Fee in his personal Australian income tax returns.
89 In a related context, we have not been assisted in endeavouring to characterise the nature of the appellant's relationship with Meisei by the evidence that he was subject to the same restrictions on access to, and egress from, the site as persons who were accepted on all sides as being employees. It is not uncommon in a project in a remote area or involving highly hazardous activities for all personnel visiting the site, even those who are indisputably independent contractors or who have no contractual connection with the head contactor, to be subject to restrictions of that kind for reasons of security or safety. Similar considerations have led us to regard as neutral the requirement for the appellant, before he became Plant Manager, to adhere to a regime of working hours and conditions which was uniform across the whole site.
