Jong v Advanced Dental Services Pty Ltd

The appeal concerned a dispute between a landlord, Advanced Dental Services Pty Ltd, and a tenant, Jong, regarding the exercise of an option to renew a commercial lease. The primary issue was whether an email exchange between the parties constituted a valid exercise of the option, thereby creating an enforceable agreement for a renewed lease.

The Court of Appeal was required to determine whether the email sent by the tenant, which referred to the lease and indicated an intention to renew, satisfied the formal requirements for exercising the option as stipulated in the lease agreement. Further, the court had to consider the relevance of subsequent conduct by both parties and whether the absence of a further guarantee, which the lease contemplated but was not explicitly demanded in the renewal communication, precluded the formation of a binding agreement.

The Court of Appeal found that the email exchange, viewed in light of the surrounding circumstances and the parties' subsequent conduct, demonstrated a clear intention by the tenant to exercise the option to renew the lease. The court held that the lease did not mandate that the tenant's communication must explicitly address the provision of a further guarantee for the renewal to be effective. The subsequent conduct of the parties, including the landlord's acceptance of rent at the renewed rate, further supported the conclusion that a binding agreement for renewal had been formed.

The appeal was dismissed, and the appellant was ordered to pay the respondent’s costs in the Court of Appeal.
