Slattery & Slattery

In the matter of *Slattery & Slattery*, Cohen J of the Supreme Court of New South Wales considered a dispute concerning the interpretation of a deed of settlement and its implications for the ongoing obligations of the parties. The central issue revolved around whether the settlement deed effectively extinguished all prior claims between the parties, including those arising from a prior partnership agreement, or if certain rights and obligations remained extant.

The court was required to determine the scope and effect of the release clause within the deed of settlement. Specifically, it had to ascertain whether the language used in the deed was sufficiently clear and unambiguous to encompass all claims, including those that might have been unknown or contingent at the time of its execution, or if it was limited to claims that were in existence and known to the parties. This involved an analysis of the principles of contractual interpretation, particularly in the context of settlement agreements where finality is a key objective.

Cohen J applied established principles of contractual construction, emphasizing that the plain and ordinary meaning of the words used in the deed should be given paramount importance. The court considered the surrounding circumstances and the purpose of the deed, which was to bring finality to the parties' disputes. Ultimately, Cohen J found that the wording of the release clause was broad enough to encompass all claims, whether known or unknown, arising from the prior partnership, thereby preventing the plaintiff from pursuing further claims. The court therefore dismissed the plaintiff's application.
