Cleary v Jeans

The parties to this appeal were Cleary (appellant) and Jeans (respondent). The dispute concerned whether the respondent's later proceedings constituted an abuse of process, given earlier proceedings between the parties. The appeal was heard in the Court of Appeal of New South Wales.

The central legal issue before the Court of Appeal was whether the respondent's subsequent claim, which was based on the truth of certain facts, was an abuse of process when earlier proceedings involving the same parties had been determined on the basis of an estoppel arising from pleadings and affidavits. The Court also considered whether the doctrine of *res judicata*, specifically *Anshun* estoppel, applied to prevent the later proceedings.

The Court reasoned that the earlier proceedings were decided on the basis of an estoppel, which prevented the appellant from amending their pleadings to assert the truth of the facts in question. The respondent's later proceedings, however, were brought to establish the truth of those very facts. The Court held that the respondent was not estopped from pursuing these later proceedings, as they were not seeking to relitigate the same issue that had been decided in the earlier proceedings. Instead, the later proceedings were based on the underlying truth of the matter, which had not been determined in the first instance. The Court distinguished this situation from a collateral challenge to a prior decision, finding no abuse of process where the prior decision was based on estoppel and the later proceedings were based on the truth.

The appeal was dismissed, and the respondent was awarded costs.
