Charles Marshall Pty Ltd v Collins

Charles Marshall Pty Ltd (the appellant) appealed to the House of Lords from a decision of the Full Court of the Supreme Court of South Australia, which had affirmed a judgment of Napier CJ. The dispute concerned the interpretation of a lease agreement and the appellant's right to exercise an option to renew the lease. The core of the disagreement lay in whether the appellant had fulfilled the conditions precedent to exercising the option, specifically the requirement to have "paid all rent and other moneys due and payable under this lease".

The central legal issue before their Lordships was whether the appellant had satisfied the condition precedent to exercising the option to renew the lease. This involved determining whether the phrase "all rent and other moneys due and payable under this lease" encompassed not only rent and moneys that had fallen due but also those that had become payable by reason of the lessee's default, even if not yet formally demanded or paid. The court had to consider the precise meaning and scope of this contractual obligation in the context of the lease agreement.

The House of Lords held that the condition precedent required the payment of all rent and other moneys that had become due and payable, irrespective of whether a formal demand had been made. Viscount Simonds, delivering the leading judgment, reasoned that the words "due and payable" were not limited to sums that had been formally demanded. He emphasised that the obligation was to pay what was due, and the lease itself created the obligation to pay rent at specified times. Therefore, any rent or other moneys that had fallen due under the lease, even if not yet demanded, were captured by the condition. The appeal was allowed, and the judgment of the Supreme Court of South Australia was reversed.
