Australian Postal Corporation v Ace Property Holdings Pty Ltd

The Australian Postal Corporation (APC) sought relief against Ace Property Holdings Pty Ltd (Ace), who leased a property from APC. APC argued that Ace had breached the terms of their lease by using the premises for activities not permitted under the lease, and by allowing a subsidiary to occupy the premises without consent. The primary issues were whether the activities conducted at the premises fell within the permitted use of "mailroom solutions operations" and whether Ace had effectively sublet the premises to its subsidiary. The court examined the specific wording of the lease, the nature of the activities at the premises, and the relationship between Ace and its subsidiary. The court determined that the activities, which included security screening, scanning of mail, and receipt of government tenders, did fall within the permitted use of "mailroom solutions operations." Regarding the subletting issue, the court held that Ace had not effectively parted with possession of the premises to its subsidiary, as Ace maintained control over the premises and the subsidiary's use of the premises was essentially Ace's own use. Therefore, no breach of the lease's subletting provisions occurred. The court also found that the lessor was estopped from claiming that the lessee breached the lease by commencing renovations without prior approval, as both parties expected approval to be sought and obtained. The court ordered further submissions from both parties to determine the appropriate orders to follow from these reasons.
