Boral Roof Tiles Ltd v O'Brien; GIO Australia Ltd v Boral Roof Tiles Ltd [No 2]

In *Boral Roof Tiles Ltd v O'Brien; GIO Australia Ltd v Boral Roof Tiles Ltd [No 2]*, the New South Wales Court of Appeal considered appeals arising from a primary judge's decision concerning defective roof tiles manufactured by Boral Roof Tiles Ltd. The dispute involved claims by property owners, represented by Mr. O'Brien, against Boral for losses and damages allegedly caused by the defective tiles, and a cross-claim by Boral against its insurer, GIO Australia Ltd, for indemnity.

The Court of Appeal was required to determine, among other things, whether Boral was liable for the defective roof tiles, the extent of the damages recoverable by the property owners, and whether GIO was obliged to indemnify Boral under its insurance policy. Key legal issues included the interpretation of the insurance policy's terms, particularly concerning exclusions and conditions precedent to liability, and the application of principles relating to the recovery of damages for defective building products.

The Court analysed the evidence regarding the manufacturing process and the performance of the roof tiles, concluding that Boral had indeed supplied defective tiles. In relation to the insurance claim, the Court examined the policy wording and relevant case law on indemnity. It found that certain exclusions within the GIO policy did not apply to the circumstances of the case, and that Boral had met the conditions required for indemnity. The Court also addressed the assessment of damages, applying principles of remoteness and causation to determine the quantum of loss suffered by the property owners.

The Court of Appeal allowed Boral's appeal against GIO, ordering GIO to indemnify Boral for its liability to the property owners. The appeals concerning the quantum of damages awarded to the property owners were also largely successful, with the Court varying the amounts awarded.
