Manns & Keeler

In *Manns & Keeler*, the Supreme Court of New South Wales was asked to determine a dispute concerning the interpretation of a deed of settlement and release. The parties involved were the plaintiffs, Manns and Keeler, and the defendant, the Commissioner of Taxation. The core of the disagreement lay in whether the settlement agreement extinguished the Commissioner's right to pursue certain tax liabilities that had arisen prior to the execution of the deed.

The central legal issue before the Court was whether the broad release contained within the deed of settlement extended to the specific tax assessments in question. This required the Court to consider the principles of contractual interpretation, particularly in the context of releases and the intention of the parties at the time the deed was entered into. The Court had to ascertain the scope of the release and whether it encompassed the Commissioner's statutory rights to assess and recover tax.

Cohen J found that the language of the deed, when read as a whole and in light of the surrounding circumstances, indicated an intention to release the Commissioner from all claims and demands whatsoever, whether known or unknown, arising out of or in connection with the matters specified in the deed. His Honour applied the principle that a clear and unambiguous release will be given its full effect, even if it covers claims that were not specifically contemplated at the time of execution, provided they fall within the general wording of the release. Consequently, the Court held that the deed effectively extinguished the Commissioner's right to pursue the tax assessments.
