The alleged contravention of s 500 by Mr Myles and Mr MacDonald
59 The Director further alleged that, in failing to comply with Mr Currie's request to leave the delineated area, Mr Myles had acted in "an improper manner".
60 The Director's case was that Mr Myles's conduct was "improper" because, as a union official whose responsibilities included protecting the safety of its members, he ought to have set a positive example by complying with the safety measures which were observed at the Site. His failure to do so meant that his conduct had fallen below the standard which reasonably could be expected of a union official conducting an investigation of safety breaches on a construction site.
61 The Director also asserted that the contravention was improper because it involved a contravention of s 499 of the Act.
62 Mr MacDonald was said to have contravened s 500 of the Act by following Mr Myles along the path. The Director contended that, although Mr Currie's words of warning were not directed at Mr MacDonald, they were made in his presence and within his hearing and he ought to have understood that Mr Currie was making a request in relation to an occupational health and safety requirement.
63 The respondents relied on the same matters by way of defences in respect of Mr MacDonald as they had done in relation to the alleged contravention by Mr Myles: see above at [52].
64 The respondents denied that the actions of the two officials could constitute "improper conduct" within the meaning of s 500 of the Act. They contended that s 500 should not be read as comprehending conduct which breached s 499 of the Act. This interpretation was said to be consistent with the object of Part 3-4, which is expressed in s 480 of the Act to be:
"The object of this Part is to establish a framework for officials of organisations to enter premises that balances:
(a) the right of organisations to represent their members in the workplace, hold discussions with potential members and investigate suspected contraventions of [relevant legislation and regulations];
(b) the right of employees and TCF award workers to receive, at work, information and representation from officials of organisations; and
(c) the right of occupiers of premises and employers to go about their business without undue inconvenience."
65 The respondents contended that, having regard to this object, the phrase "act in an improper manner" was intended only to apply to conduct that upset the balance of competing interests and caused employers "undue inconvenience".
66 They also sought to advance the submission, which had been rejected in Setka v Gregor (No 2), that the words "act in an improper manner" must be read ejusdem generis with the words "hinder or obstruct".
67 They contended, in reliance on Darlaston v Parker, in the passage set out above at [47], that the words "intentionally hinder or obstruct" are intended to cover "an 'appreciable' obstruction or interference" and not "a trivial act". They argued that a similar approach should be taken towards the interpretation of "otherwise act in an improper manner". That is, that the phrase is not intended to cover conduct which is less egregious than a "hindrance" or "obstruction". The use of the word "otherwise", they submitted, suggests that hindering and obstructing are two kinds of improper conduct and that "act in an improper manner" is intended to catch other kinds of improper conduct of equivalent or greater seriousness.
68 It was further contended that, having regard to the civil penalty regime, s 500 must be intended to only capture conduct that is not proscribed by other provisions in Part 3-4 of the Act and which upsets the balance provided for in s 480 in an "appreciable" manner.
69 The construction of s 500 is to be undertaken having regard to its text in the context of the Act as a whole and its general purpose: see Alcan (NT) Alumina Pty Ltd v Commissioner of Territory Revenue (2009) 239 CLR 27 at 46-7. The section prohibits permit holders from intentionally hindering or obstructing any person or otherwise acting in an improper manner when exercising rights conferred on them under Part 3-4 of the Act. The terms of the proscription are clear. They are one of the means adopted by the legislature in order to advance the object contained in s 480. There is no justification for reading down the plain words of the section in the ways proposed by the respondents. There is no reason why the same conduct might not be found to give rise to a contravention of both ss 499 and 500. While such an overlap may have implications for the fixing of appropriate pecuniary penalties, it has no bearing on the question of whether or not s 500 has been contravened.
70 I am bound by the Full Court's decision in Setka v Gregor (No 2) to reject the respondent's submission that the reach of the phrase "act in an improper manner" is to be confined by the words which immediately precede it.
71 I accept the Director's submission that both Mr Myles and Mr MacDonald acted in an improper manner by proceeding along the barricaded pathway after Mr Currie had told them that they should not do so. The conduct of both men, in ignoring Mr Currie's admonition, was conduct which fell below the requisite standard which applied to them as union officials who had repeatedly emphasised that they were on the Site to ensure that appropriate health and safety standards were being observed.
