Ibbotson and Ors v Chaney and Ors

The applicants, Ibbotson and others, sought to restrain the respondents, Chaney and others, from continuing certain proceedings in the Supreme Court of Western Australia. The dispute concerned the proper construction of a deed of settlement and release, and whether it operated to release the respondents from all claims, including those arising from alleged breaches of fiduciary duty. The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the broad release contained in the deed of settlement extended to claims for breach of fiduciary duty that were not specifically contemplated or referred to at the time the deed was executed. The applicants argued that the release was intended to cover only those claims that were the subject of the litigation being settled, and not unknown or future claims, particularly those involving a breach of fiduciary duty.

The Court considered the principles of contractual interpretation, particularly in relation to releases. It was held that while a release can be given a wide operation, its scope is generally determined by the language used and the context in which it was made. The Court found that the deed of settlement, by its express terms, released the respondents from "all and every action, suit, claim and demand whatsoever". This broad language, in the absence of any express limitation or contrary intention, was sufficient to encompass claims for breach of fiduciary duty, even if those specific claims were not in the contemplation of the parties at the time of settlement. The Court emphasised that the parties had the opportunity to qualify the release if they had intended to exclude certain types of claims, but they did not do so.

The High Court therefore dismissed the application for an injunction, finding that the deed of settlement operated to release the respondents from the claims brought against them in the Supreme Court of Western Australia.
