WILLIAMS & LISLE

The case of *Williams & Lisle* concerned a dispute between the parties regarding the interpretation of a deed of settlement. The primary issue before Dunkley J was whether the settlement agreement, which included a release of claims, effectively extinguished all claims that the plaintiff, Williams, had against the defendant, Lisle, including those that had not been specifically contemplated or identified at the time the deed was executed.

The court was required to determine the scope of the release contained within the deed of settlement. Specifically, it needed to ascertain whether the wording of the release was sufficiently broad to encompass unknown or unquantified claims, or if it was limited to those claims that were in existence and known to the parties at the time of settlement. This involved an analysis of the contractual language used in the deed and the application of established principles of contractual interpretation.

Dunkley J applied the principles of contractual interpretation, emphasising that the plain and ordinary meaning of the words used in the deed should be given effect. His Honour found that the release clause was drafted in wide and comprehensive terms, using phrases such as "all and every action, suit, claim and demand whatsoever". The court concluded that, in the absence of any ambiguity or evidence to suggest a contrary intention, the release extended to all claims, whether known or unknown, that Williams had against Lisle at the time the deed was executed. The court therefore held that the claims brought by Williams were barred by the deed of settlement.
