Australian Remediation Services v Earth Tech Engineering

In the Federal Circuit Court of Australia, Australian Remediation Services sought to restrain Earth Tech Engineering from filing an adjudication certificate under the Building and Construction Industry Security of Payment Act 1999. The dispute arose from a construction contract where Australian Remediation Services provided services to Earth Tech Engineering. Australian Remediation Services claimed that the certificate issued by the adjudicator was invalid due to procedural irregularities and sought an injunction to prevent Earth Tech Engineering from taking any action based on the certificate. The court was required to determine whether the balance of convenience favoured granting the injunction and whether a bank guarantee should be provided as a condition of the injunction.

The court considered the balance of convenience, examining the potential harm to each party if the injunction was granted or denied. It noted the significant prejudice Australian Remediation Services would suffer if forced to pay an amount that it claimed was not owed, and the relatively lesser impact on Earth Tech Engineering if required to delay payment. The court also assessed the likelihood of Australian Remediation Services succeeding on the merits of the case. Given the strong arguments presented by Australian Remediation Services regarding the invalidity of the adjudication certificate, the court found that the balance of convenience favoured granting the injunction. The court further determined that a bank guarantee should be provided by Australian Remediation Services as a condition of the injunction to mitigate potential losses to Earth Tech Engineering if the injunction was ultimately found to be wrongly granted.

The court issued an injunction restraining Earth Tech Engineering from filing the adjudication certificate and requiring Australian Remediation Services to provide a bank guarantee. The injunction was subject to Earth Tech Engineering being allowed to apply to set it aside if Australian Remediation Services failed to maintain the guarantee. The court's decision provided a temporary reprieve for Australian Remediation Services pending further determination of the underlying dispute.
