The relevant common law principles
8 The primary judge summarised the principles in Personnel Contracting and Jamsek as follows:
[17] First, where the rights and duties of the parties are comprehensively committed to a written contract, the legal rights and obligations established by the contract are decisive of the character of the relationship provided that the validity of the contract has not been challenged as a sham, or that the terms of the contract have not been varied, waived or are subject to an estoppel: Personnel Contracting at [43], [44], [47], [59] (Kiefel CJ, Keane and Edelman JJ), [172] (Gordon J, Steward J relevantly agreeing at [203]). The task is to construe and characterise the contract made between the parties at the time it was entered into: Personnel Contracting at [174] (Gordon J).
[18] Second, in order to ascertain the relevant legal rights and obligations, the contract of employment must be construed in accordance with the established principles of contractual interpretation: Personnel Contracting at [60] (Kiefel CJ, Keane and Edelman JJ), [124] (Gageler and Gleeson JJ), [173] (Gordon J). In that respect, regard may be had to the circumstances surrounding the making of the contract, as well as to events and circumstances external to the contract which are objective, known to the parties at the time of contracting and which assist in identifying the purpose or object of the contract: Personnel Contracting at [174]-[175] (Gordon J); Jamsek at [61] (Kiefel CJ, Keane and Edelman JJ), referring to Codelfa Construction Pty Ltd v State Rail Authority of NSW (1982) 149 CLR 337 at 352. The nature of the specific job that the putative employee applied for and the nature and extent of any tools or equipment they have to supply for that job may also be relevant: Personnel Contracting at [175] (Gordon J). It is, however, generally not legitimate to use in aid of the construction of a contract anything which the parties said or did after it was made: Personnel Contracting at [176] (Gordon J).
[19] Third, and flowing from the first two principles, the characterisation of the relationship between the parties is not affected by circumstances, facts or occurrences arising between the parties that have no bearing on their legal rights: Personnel Contracting at [44] (Kiefel CJ, Keane and Edelman JJ), [173]-[178] (Gordon J); Jamsek at [109] (Gordon and Steward JJ). A "wide-ranging review of the entire history of the parties' dealings" is neither necessary nor appropriate: Personnel Contracting at [59] (Kiefel CJ, Keane and Edelman JJ); see also [185]-[189] (Gordon J). For a "matter to bear upon the ultimate characterisation of a relationship, it must be concerned with the rights and duties established by the parties' contract, and not simply an aspect of how the parties' relationship has come to play out in practice but bearing no necessary connection to the contractual obligations of the parties": Personnel Contracting at [61] (Kiefel CJ, Keane and Edelman JJ) (emphasis added).
[20] It follows that the fact that the parties' subsequent conduct may not have precisely aligned with their contractual rights and obligations, or the fact that a particular contractual right may have never been exercised or utilised, will generally be irrelevant when it comes to characterising the relationship. That is so unless the manner in which the parties conducted themselves after entering into the contract was such as to establish that the contract was a sham, or that the contract had been varied, or that certain rights under the contract were subject to an estoppel.
[21] Fourth, the contractual provisions that may be relevant in determining the nature of the relationship include, but are not limited to, those that deal with the mode of remuneration, the provision and maintenance of equipment, the obligation to work, the hours of work, the provision for holidays, the deduction of income tax, the delegation of work and the right to exercise direction and control: Personnel Contracting at [113] (Gageler and Gleeson JJ); [174] (Gordon J), referring to Brodribb at 24 (Mason J); see also 36-37 (Wilson and Dawson JJ).
[22] In Brodribb, Wilson and Dawson JJ said (at 36-37) that the indicia which suggested an employment relationship included "the right to have a particular person do the work, the right to suspend or dismiss the person engaged, the right to the exclusive services of the person engaged and the right to dictate the place of work, hours of work and the like", whereas those that suggested a contract for services included "work involving a profession, trade or distinct calling on the part of the person engaged, the provision by him of his own place of work or of his own equipment, the creation by him of goodwill or saleable assets in the course of his work, the payment by him from his remuneration of business expenses of any significant proportion and the payment to him of remuneration without deduction for income tax". Their Honours were, however, careful to note (at 37) that "any attempt to list the relevant matters, however incompletely, may mislead because they can be no more than a guide to the existence of the relationship of master and servant". It should also be emphasised that the list of possible indicia must now be approached on the basis that the focus is on the parties' contractual rights and obligations relevant to those matters, at least where the contract is wholly in writing, not on the way in which the work was actually carried out.
[23] Fifth, the characterisation of the relationship as one of service or employment involving an employer and employee, as opposed to a relationship involving an independent contractor providing services to a principal, often hinges on two considerations. The first consideration is the extent to which the putative employer has the right to control how, where and when the putative employee performs the work: Personnel Contracting at [73]-[74] (Kiefel CJ, Keane and Edelman JJ); [113] (Gageler and Gleeson JJ); see also Brodribb at 24 (Mason J) and 36-37 (Wilson and Dawson JJ). The second is the extent to which the putative employee can be seen to work in his or her own business, as distinct from the business of the putative employer - the so-called "own business/employer's business" dichotomy: Personnel Contracting at [36]-[39] (Kiefel CJ, Keane and Edelman JJ); [113] (Gageler and Gleeson JJ); cf [180]-[183] (Gordon J). Neither of those considerations are determinative and both involve questions of degree.
[24] As for the element of control, "the existence of a right of control by a putative employer over the activities of a putative employee serves to sensitise one to the subservient and dependent nature of the work of an employee, so as to assist in an assessment of whether a relationship is properly to be regarded as a contract of service rather than a contract for services": Personnel Contracting at [73] (Kiefel CJ, Keane and Edelman JJ).
[25] As for the "own business/employer's business" dichotomy, it also "usefully focusses attention upon those aspects of the relationship generally defined by the contract which bear more directly upon whether the putative employee's work was so subordinate to the employer's business that it can be seen to have been performed as an employee of that business rather than as part of an independent enterprise": Personnel Contracting at [39] (Kiefel CJ, Keane and Edelman JJ); cf [180]-[182] (Gordon J). Another way of framing the question, which focusses more directly on the terms of the contract, is whether the person "is contracted to work in the business or enterprise of the purported employer": Personnel Contracting at [183] (Gordon J) (emphasis in original). One consequence of answering that question in the negative may be that the person is not an employee.
[26] Sixth, a "label" which the parties may have chosen to describe their relationship is not determinative of the nature of the relationship and will rarely assist the court in characterising the relationship by reference to the contractual rights and duties of the parties: Personnel Contracting at [63]-[66] (Kiefel CJ, Keane and Edelman JJ); [127] (Gageler and Gleeson JJ); [184] (Gordon J). The parties' "legitimate freedom to agree upon the rights and duties which constitute their relationship" does not "extend to attaching a 'label' to describe their relationship which is inconsistent with the rights and duties otherwise set forth" - to permit otherwise would elevate the freedom to "a power to alter the operation of statute law to suit … the interests of the party with the greater bargaining power": Personnel Contracting at [58] (Kiefel CJ, Keane and Edelman JJ).
[27] The characterisation of a relationship as being either one of employer and employee, or one involving the engagement of an independent contractor, is ultimately an evaluative judgment that takes into account the totality of the parties' contractual rights and obligations. The exercise may not necessarily be straightforward because, in some cases at least, the parties' contractual rights and obligations may point in different directions. The evaluative exercise also should not be approached on the basis that there is some checklist against which ticks and crosses may be placed so as to produce the right answer. Some degree of uncertainty is unavoidable, particularly in the case of many modern-day work or service contracts.
9 There was no dispute between the parties that this summary was accurate.
10 The decisions of the Privy Council in Australian Mutual Provident Society v Chaplin [1978] UKPC 7; 18 ALR 385 and Narich Pty Ltd v Commissioner of Pay-roll Tax [1983] 2 NSWLR 597 were central to the reasoning of Kiefel CJ, Keane and Edelman JJ in Personnel Contracting that the High Court was doing no more than restating what the law had always been, and disagreeing with the proposition that, where there is a comprehensive written contract, one could look to the performance of the contract in addition to the terms of the contract itself. At [45], their Honours set out the following proposition which the Privy Council in Narich at 601 had drawn from Chaplin:
…where there is a written contract between the parties whose relationship is in issue, a court is confined, in determining the nature of that relationship, to a consideration of the terms, express or implied, of that contract in the light of the circumstances surrounding the making of it; and it is not entitled to consider also the manner in which the parties subsequently acted in pursuance of such contract.
11 At [46], Kiefel CJ, Keane and Edelman JJ referred to Australian courts continuing to recognise the decisions in Chaplin and Narich as authoritative. At the end of [48], their Honours stated that it would be a "large step" to interpret the Australian cases which had followed Chaplin and Narich as justifying a departure from the settled law as expressed in those cases.
12 A different view was expressed by Gageler and Gleeson JJ at [143] on this matter of principle:
The true principle, in accordance with what we understand to have been the consistent doctrine of this Court until now, is that a court is not limited to considering the terms of a contract and any subsequent variation in determining whether a relationship established and maintained under that contract is a relationship of employment. The court can also consider the manner of performance of the contract. That has been and should remain true for a relationship established and maintained under a contract that is wholly in writing, just as it has been and should remain true for a relationship established and maintained under a contract expressed or implied in some other form or in multiple forms.
13 Gageler and Gleeson JJ were of the view that Narich contained an error of principle which they explained in the following way at [130]:
The error of common law principle in Narich lay in conflation of the distinction between the relationship of employment and the contract under which the relationship is established and maintained. Focusing exclusively on the terms of the contract loses sight of the purpose for which the characterisation is undertaken. That purpose is to characterise the relationship.
14 Their Honours also stated at [132]:
There will be cases, of which Narich and Chaplin may well have been examples, in which an examination of the manner of performance of a written contract will reveal nothing of significance about a relationship in fact established and maintained by the parties under the contract that cannot be gleaned from an examination of the contractual terms. But there will be cases where, without any variation to the terms of a written contract, the true character of a relationship in fact established and maintained under the contract will be revealed through the manner of the performance of the contract. That will be so where the terms of the written contract are sufficiently opaque or obscure to admit of different manners of performance. And it will be especially so where such a contract is a standard form written contract couched in language that might arguably have been chosen by the putative employer to dress up the relationship to be established and maintained as something somewhat different from what it might turn out to be.
15 Chaplin was an appeal to the Judicial Committee of the Privy Council from the Full Court of the Supreme Court of South Australia. Clause 3 of the contract at issue stated that the relationship between the AMP and one of its representatives was one of principal and agent and not of master and servant. The contract was held by the Chief Justice to be one of employment, notwithstanding this label. The decision turned on the terms of the contract, not the way in which it had in fact been performed.
16 Lord Fraser of Tullybelton, delivering the judgment of the Judicial Committee, considered a number of the contractual clauses, observing at 391 that none of them were conclusive on the nature of the relationship. His Lordship then turned to the representative's right to enter into a partnership in connection with the AMP's business, and his power to appoint subagents. The former was described by Lord Fraser as unusual, but not absolutely inconsistent with a relationship of master and servant; the latter was described as being an even stronger indication of inconsistency with the representative being an employee. Referring to the agent's power to appoint subagents, Lord Fraser stated at 391:
In the present case there appears to be nothing in the written agreement to prevent the respondent from delegating the whole performance of his work to one or more sub-agents. In the opinion of their Lordships this power of unlimited delegation is almost conclusive against the contract being a contract of service - see Aliyah op cit p 59, a passage cited by the learned Chief Justice. The unlimited extent of the power of delegation is one consequence of the striking absence of any express obligation upon the respondent to perform any particular duties, or to work any particular hours, or indeed to do any work at all on behalf of the Society.
17 In Stevens v Brodribb Sawmilling Company Pty Ltd [1986] HCA 1; 160 CLR 16 at 26, Mason J (with whom Brennan J agreed) cited Chaplin at 391 as authority for the proposition that the power to delegate was an important factor in deciding whether a worker was a servant or an independent contractor. Wilson and Dawson JJ referred to Chaplin at 391, noting the view expressed in that case that an unlimited power of delegation was almost conclusive against the contract being one of service: Brodribb at 38.
18 Neither Personnel Contracting nor Jamsek cast any doubt on the correctness of Brodribb. In Personnel Contracting, Kiefel CJ, Keane and Edelman JJ said:
(a) at [34]: that the reference in Brodribb to the totality of the relationship in that case did not mean that the factors identified to be relevant are of equal weight in the characterisation of the relationship, with some understanding of the relative significance of the various factors being desirable;
(b) at [56]: that Brodribb was a case in which the parties had not committed the terms of their relationship to a written contract, unlike in Personnel Contracting or Jamsek and, it might be added, unlike the present case. Where there is no written contract, the terms of the contract might need to be determined by reference to conduct. Their Honours noted that Mason J's reference to the "totality of the relationship" was made in the context of emphasising that the right of one party to control the work was not the only relevant factor. It was not an invitation to broaden the inquiry beyond the contractual rights and duties of the parties; and
(c) at [57]: that there was no suggestion in any of the judgments in Brodribb that the Justices entertained any misgivings about the statements of principle in Chaplin and Narich.
19 Gordon J also endorsed Chaplin and referred to the contractual right to delegate the work as one of the indicia of the nature of the relationship being that of an independent contractor: Personnel Contracting at [174].
20 Clause 2.1(g) of the written contracts in Jamsek provided that the partnerships agreed to "[n]ot engage or use the services of a driver for the vehicle without prior and continuing approval by [the company]": Jamsek at [18].
21 Kiefel CJ, Keane and Edelman JJ said that the clause did not exclude the possibility of engaging alternative drivers with the company's approval, with the right to grant or withhold approval recognising the company's interest in the safe transport of its goods: Jamsek at [55].
22 Gordon and Steward JJ at [103] described cl 2.1(g) as making explicit that performance of the contractual obligations was not personal to the workers, and cited both Brodribb at 24 and 36-37 and Personnel Contracting at [198]. The requirement for consent was not suggested as requiring a different conclusion.
