VACC Insurance Ltd v BP Australia Ltd

VACC Insurance Ltd appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales concerning a dispute over contribution or indemnity under section 5 of the *Law Reform (Miscellaneous Provisions) Act 1946* (NSW). The primary dispute involved a public liability insurance policy and an alleged breach of its conditions. BP Australia Ltd was the respondent.

The central legal issues before the Court of Appeal were whether VACC Insurance Ltd was estopped from pursuing its claim for contribution or indemnity. Specifically, the court considered the application of issue estoppel and *Anshun* estoppel, and whether the conduct of VACC Insurance Ltd in previous proceedings was reasonable, thereby precluding it from raising the current claim. The court also examined the concept of "approbating and reprobating" in the context of the parties' actions.

The Court of Appeal allowed the appeal, finding that VACC Insurance Ltd was indeed estopped from bringing its claim. The court reasoned that the issues raised in the current proceedings were, or ought to have been, litigated in earlier proceedings between the parties. The court determined that it would be unreasonable to allow VACC Insurance Ltd to pursue a claim that could and should have been advanced previously, thereby preventing it from "approbating and reprobating". The principles of issue and *Anshun* estoppel were applied to prevent VACC Insurance Ltd from relitigating matters that had already been determined or could have been determined.
