Lake Maintenance (NSW) Pty Ltd v Bone

Lake Maintenance (NSW) Pty Ltd sought an interlocutory injunction to stay the enforcement of a judgment against Bone. The judgment had been entered after Bone failed to make payments due under a deed executed as a settlement of proceedings. The deed provided that the plaintiff would enter judgment if the defendant did not pay the outstanding amount on the second anniversary of the deed. The deed also contained provisions allowing the defendant to commence and pursue proceedings against a third party. Lake Maintenance contended that the enforcement of the judgment was delayed until the completion of the defendant's proceedings against the third party. They further argued that the defendant's mistaken belief regarding the construction of the deed led to an estoppel in pais, preventing Lake Maintenance from enforcing the judgment.

The court was required to determine whether the enforcement of the judgment was indeed delayed until the completion of the third party proceedings and whether a term could be implied into the deed to achieve this delay. Additionally, the court needed to assess whether Lake Maintenance was estopped from enforcing the judgment due to the defendant's mistaken belief in the construction of the deed.

The court found that there was no serious question to be tried regarding the proper construction of the deed, which did not delay the enforcement of the judgment until the completion of the third party proceedings. The court also ruled that no term could be implied into the deed to delay enforcement. Furthermore, the court held that Lake Maintenance was not estopped from enforcing the judgment by the defendant’s mistaken belief in the construction of the deed. Consequently, the application for the interlocutory injunction was dismissed.

The court declined to grant the interlocutory injunction, allowing Lake Maintenance to enforce the judgment as per the terms of the deed. The defendant was ordered to pay the outstanding amount to the plaintiff within the specified timeframe, and the plaintiff was permitted to enter judgment if the payment was not received by the second anniversary of the deed.
