Thiess Pty Ltd v Industrial Magistrate Elizabeth Hall

The appeal was brought by Thiess Pty Ltd, the appellant, against the decision of an industrial magistrate, Elizabeth Hall, the respondent, in relation to a complaint filed by the third respondent regarding alleged breaches of the Workplace Health and Safety Act 1995. The complaint contained charges expressed in the alternative. The appellant challenged the decision of the primary judge, who held that the industrial magistrate had an implied power to strike out part of the complaint where it was necessary to enable the court to act effectively within its jurisdiction. The appellant argued that the principle of finality of judgment should preclude the court from revisiting an earlier decision that summary charges could not be brought in the alternative.

The primary legal issues were whether the principle of finality of judgment precluded the court from revisiting an earlier decision that summary charges could not be brought in the alternative, and whether the case was one of incorrect joinder under section 43 of the Justices Act so as to enliven the express power to require election contained in section 43(3)(a), with an implied power to strike out the count not proceeded on. The appellant had conceded below that section 43(3)(a) was not applicable, but the court nevertheless considered whether the point should be decided.

The court held that the principle of finality of judgment did not preclude the court from revisiting the earlier decision, as the principle of finality of judgment was not absolute and could be displaced in certain circumstances. The court also held that the case was not one of incorrect joinder under section 43 of the Justices Act, as the complaint was not in a form authorised by section 43 of the Justices Act. The court further held that an industrial magistrate had an implied power to strike out part of the complaint where it was necessary to enable the court to act effectively within its jurisdiction, such a power not being inconsistent with the express powers of election and amendment contained respectively in section 43 and section 48 of the Justices Act 1886.

The appeal was dismissed, and the parties' submissions on costs were to be received by the court within 14 days of judgment delivery.
