Manieri and Anor v Cirillo

The High Court of Australia considered an appeal concerning a dispute between Manieri and Cirillo. The core of the disagreement related to the interpretation and enforceability of a written agreement, specifically a deed, which purported to settle a prior dispute between the parties. The appeal arose from a decision of the Supreme Court of Victoria.

The central legal issue before the High Court was whether the deed, which contained a release of all claims, was effective to prevent Cirillo from pursuing a claim for damages for deceit against Manieri. This required the court to determine the scope and effect of the release clause within the deed, particularly in light of allegations of deceit that predated the deed's execution.

Crennan J, delivering the judgment, reasoned that the language of the deed, particularly the broad and unqualified nature of the release, indicated a clear intention by the parties to compromise all existing disputes and claims, whether known or unknown, and whether arising in contract or tort. His Honour applied the principle that clear and unambiguous contractual language should be given its ordinary meaning, and that a release clause, when properly construed, will encompass all claims that were in contemplation or could have been brought at the time of its execution, even if the specific cause of action for deceit was not explicitly mentioned. The court found that the deed effectively extinguished Cirillo's right to pursue the deceit claim.

The High Court allowed the appeal, setting aside the orders of the Supreme Court of Victoria and ordering that Cirillo's claim for deceit be dismissed.
