Bensons Property Group Pty Ltd v Key Infrastructure Australia Pty Ltd

Bensons Property Group Pty Ltd initiated legal proceedings against Key Infrastructure Australia Pty Ltd, challenging the enforceability of a development management agreement. The crux of the dispute centred around whether Key Infrastructure breached the agreement by sending a letter to a council, which Bensons alleged deprived them of a substantial chance of obtaining a planning permit by a specified date. Additionally, Bensons contended that the letter constituted a breach of an implied duty of cooperation and resulted in loss and damage. The matter was heard in the Supreme Court of New South Wales.

The primary legal issues before the court were whether the letter sent by Key Infrastructure to the council deprived Bensons of a substantial chance of obtaining the planning permit by the stipulated deadline and whether this action constituted a breach of an implied duty of cooperation. Furthermore, the court had to determine if the letter caused Bensons any loss and damage. These issues required careful consideration of the terms of the agreement, the implications of the prevention principle, and the consequences of any alleged breach.

In delivering the judgment, the court found that the letter sent by Key Infrastructure did indeed deprive Bensons of a substantial chance of obtaining the planning permit by the deadline. This finding was grounded in the application of the prevention principle, which posits that a party who acts in a manner that prevents another party from fulfilling a contractual obligation has breached that contract. Additionally, the court held that by sending the letter, Key Infrastructure breached an implied duty of cooperation, as it acted in a manner that was contrary to the collaborative spirit intended by the agreement. Finally, the court concluded that Bensons suffered loss and damage as a result of Key Infrastructure’s actions. This decision underscores the importance of adhering to contractual obligations and the potential ramifications of failing to cooperate effectively.
