Accepted principles
53 The principles in relation to the imposition of civil penalties are well established. They were summarised recently by O'Bryan J in Australian Competition and Consumer Commission v Uber B.V. [2022] FCA 1466 and Australian Competition and Consumer Commission v BlueScope Steel Limited (No 6) [2023] FCA 1029. I gratefully adopt his Honour's summaries and repeat the principles relevant to this proceeding below.
54 First, the penalty to be imposed under s 44AAG(2) of the Competition and Consumer Act is a penalty that the Court considers to be appropriate.
55 Second, the principal object of imposing a civil penalty is deterrence; both the need to deter repetition of the contravening conduct by the contravener (specific deterrence) and to deter others who might be tempted to engage in similar contraventions (general deterrence): Australian Competition and Consumer Commission v TPG Internet Pty Ltd [2013] HCA 54; 250 CLR 640 at [65] per French CJ, Crennan, Bell and Keane JJ; FWBII at [55] per French CJ, Kiefel J (as her Honour then was), Bell, Nettle and Gordon JJ and [110] per Keane J. The Court must seek to "put a price on contravention that is sufficiently high to deter repetition by the contravenor and by others who might be tempted to contravene" the relevant statute: Australian Building and Construction Commissioner v Pattinson [2022] HCA 13; 274 CLR 450 at [15] per Kiefel CJ, Gageler J (as his Honour then was), Keane, Gordon, Steward and Gleeson JJ, citing TPC v CSR at [50] per French J (as his Honour then was). The penalty imposed should not be regarded by the contravenor or others as an acceptable cost of doing business: TPG at [66] per French CJ, Crennan, Bell and Keane JJ) citing Singtel Optus Pty Ltd v Australian Competition and Consumer Commission [2012] FCAFC 20; 287 ALR 249 at [62]-[63]. A penalty should nonetheless be proportionate in the sense of striking "a reasonable balance between deterrence and oppressive severity" (Pattinson at [41], [46]-[47]). The question, therefore, is what is required to achieve deterrence in the specific circumstances of the case.
56 Third, the level of penalty required to achieve the objective of deterrence in a given case depends upon the facts and circumstances of the case. As set out in paragraph 47 above, s 234 of the NGL requires the Court to have regard to certain mandatory matters. Additional factors relevant to this case include the size and financial position of Santos, whether senior management were involved, the level of co-operation with the AER and Santos' compliance culture.
57 The majority in Pattinson confirmed that regard may properly be had to the above factors as potentially relevant considerations in the assessment of penalty, while recognising that they are not a rigid catalogue of matters for attention nor a legal checklist (at [18] and [19]). In discussing those factors, the majority observed (at [46]-[47]), in the context of s 546 of the Fair Work Act 2009 (Cth):
... It is important to recall that an "appropriate" penalty is one that strikes a reasonable balance between oppressive severity and the need for deterrence in respect of the particular case. A contravention may be a "one-off" result of inadvertence by the contravenor rather than the latest instance of the contravenor's pursuit of a strategy of deliberate recalcitrance in order to have its way. There may also be cases, for example, where a contravention has occurred through ignorance of the law on the part of a union official, or where the official responsible for a deliberate breach has been disciplined by the union. In such cases, a modest penalty, if any, may reasonably be thought to be sufficient to provide effective deterrence against further contraventions.
The penalty that is appropriate to protect the public interest by deterring future contraventions of the Act may also be moderated by taking into account other factors of the kind adverted to by French J in CSR. For example, where those responsible for a contravention of the Act express genuine remorse for the contravention, it might be considered appropriate to impose only a moderate penalty because no more would be necessary to incentivise the contravenors to remain mindful of their remorse and their public expressions of that remorse to the court. Similarly, where the occasion in which a contravention occurred is unlikely to arise in the future because of changes in the membership of an industrial organisation, a modest penalty may be appropriate having regard to the reduced risk of future contraventions.
58 Fourth, in fixing a penalty, the Court should have regard to the maximum penalty prescribed by the legislature: see Markarian v The Queen [2005] HCA 25; 228 CLR 357. However, the statutory maximum penalty is "but one yardstick that ordinarily must be applied" and must be treated as "one of a number of relevant factors": Australian Competition and Consumer Commission v Reckitt Benckiser (Australia) Pty Ltd [2016] FCAFC 181; 340 ALR 25 at [155]-[156]. In Pattinson, the majority rejected an approach whereby the Court seeks to grade contraventions on a "scale of increasing seriousness, with the maximum to be reserved exclusively for the worst category of contravening conduct" (at [49]). The majority explained (at [55]) that:
... the maximum penalty does not constrain the exercise of the discretion under s 546 (or its analogues in other Commonwealth legislation), beyond requiring "some reasonable relationship between the theoretical maximum and the final penalty imposed". This relationship of "reasonableness" may be established by reference to the circumstances of the contravenor as well as by the circumstances of the conduct involved in the contravention. That is so because either set of circumstances may have a bearing upon the extent of the need for deterrence in the penalty to be imposed. And these categories of circumstances may overlap.
59 Fifth, in common with criminal sentencing, determining a civil penalty usually involves multi-factorial decision-making, identifying and balancing all the factors relevant to the contravention, and where the result is arrived at by a process of "instinctive synthesis" of the relevant factors: Reckitt Benckiser at [44].
