Mitchell Supermarkets Pty Ltd v CJR Asset Management Pty Ltd

Mitchell Supermarkets Pty Ltd (Mitchell) commenced proceedings against CJR Asset Management Pty Ltd (CJR), the landlord, asserting breaches of covenant under the lease agreement. Mitchell alleged that CJR had derogated from their grant, thereby interfering with Mitchell's quiet enjoyment of the premises. The case was heard in the Supreme Court of New South Wales. Mitchell contended that CJR's actions, including the installation of an inadequate car park barrier, constituted a significant interference with their business operations and amounted to a breach of the covenant of quiet enjoyment. Additionally, Mitchell sought termination of the lease due to the alleged breaches.

The primary legal issues revolved around whether CJR's actions constituted a derogation from the grant and a breach of the covenant of quiet enjoyment. The court had to assess whether the interference was substantial enough to justify termination of the lease. Mitchell argued that the inadequate car park barrier disrupted their business operations and constituted a material interference. CJR, on the other hand, contended that the barrier did not materially affect Mitchell's use and enjoyment of the premises and that any inconvenience was not significant enough to warrant termination.

The court found that CJR had indeed derogated from their grant by installing an inadequate car park barrier, which materially interfered with Mitchell's ability to conduct business. The court held that this interference amounted to a breach of the covenant of quiet enjoyment. Consequently, the court determined that the breaches were substantial enough to justify termination of the lease. The court granted Mitchell's application for termination of the lease and ordered specific relief, including payment of damages and other costs.
