Bankwest a Division of Commonwealth Bank of Australia v Mann [No 2]

The appeal in Bankwest a Division of Commonwealth Bank of Australia v Mann [No 2] concerned a dispute over the enforceability of a guarantee provided by the defendant, Mann, for a loan made to a company. The trial judge had ruled that part of Mann’s defence, which challenged the validity of the guarantee, had to be struck out. Mann sought to appeal this decision on the basis that the trial judge had misapplied the law. The case was heard in the Supreme Court of Western Australia.

The primary legal issue was whether the trial judge correctly applied the law when deciding to strike out part of Mann's defence. Specifically, the court needed to determine whether the judge erred in finding that the defence was factually distinct and required a separate proceeding to be resolved. The appeal hinged on whether the trial judge had considered all relevant facts and applied the correct legal principles in making his decision.

The court examined the judge's reasoning and found that he had properly considered all the evidence and applied the relevant legal principles. The trial judge had concluded that the defence raised issues that were separate and distinct from the main proceedings and required a determination based on facts unique to the defence itself. The appeal court upheld the trial judge’s decision, affirming that the judge had correctly exercised his discretion. The appeal was therefore dismissed.
