United Motor Search Pty Ltd v Hanson Construction Materials Pty Ltd

In the case of United Motor Search Pty Ltd v Hanson Construction Materials Pty Ltd, the dispute centred around the termination of a contractual relationship between the first respondent, Hanson Construction Materials Pty Ltd, and the first applicant, United Motor Search Pty Ltd, concerning the carriage of pre-mixed concrete. The first applicant, an owner-driver of concrete trucks, claimed that the first respondent had wrongfully terminated their contract, which they asserted was due to their industrial activities in support of the Transport Workers Union (TWU) and their involvement in Fair Work Australia proceedings. The first respondent denied any wrongdoing and claimed the termination was based on legitimate business reasons.

The primary legal issue before the court was whether the first applicant had established a serious question to be tried concerning adverse action in contravention of the Fair Work Act 2009 (Cth). The court was required to determine whether the first applicant had demonstrated a sufficient likelihood of success at trial and whether the balance of convenience favoured granting an interlocutory injunction. This involved applying the principles set out in Australian Broadcasting Corporation v O’Neill (2006) 227 CLR 57, which provide the framework for assessing interlocutory injunction applications in cases involving serious questions to be tried.

The court found that the first applicant had established a serious question to be tried regarding the first respondent's conduct. The evidence, including the correspondence and agreements between the parties, suggested that the first applicant had a legitimate expectation of continued contractual relations until 2020, based on their upgrade to a larger truck. The court was persuaded that the first respondent's actions were influenced by the first applicant's industrial activities, which potentially contravened the Fair Work Act. The court also considered that the balance of convenience favoured granting the interlocutory relief, as the denial of such relief would cause significant and irreparable harm to the first applicant's business.

Accordingly, the court granted the interlocutory injunction, requiring the first respondent to provide casual cartage services to the first applicant until the substantive proceedings were concluded. The court emphasised that damages would not be an adequate remedy in this case due to the potential disruption to the first applicant's business affairs. The parties were granted liberty to apply for further orders as necessary, and the costs of the interlocutory application were reserved for later determination.
