The Gull Lexington Group Pty Ltd v Laguna Bay (Banongill) Agricultural Pty Ltd

The Gull Lexington Group Pty Ltd sought summary judgment against Laguna Bay (Banongill) Agricultural Pty Ltd for breach of contract. The dispute centred on an asset sale agreement, specifically the valuation of livestock by an expert appointed by the parties. The matter was heard in the Supreme Court of Queensland, with Justice Byrne presiding. The primary issue before the court was whether the expert's valuation of the livestock was conducted in accordance with the terms of the agreement and whether the expert's impartiality was compromised. The court was required to determine whether the expert's failure to act impartially or in accordance with the terms of the agreement warranted setting aside the valuation.

The court examined the asset sale agreement, which required the expert to value the livestock "inclusive of any progeny." The expert valued the merino lambs and ewes as a single unit, which the plaintiff argued did not comply with the agreement's terms. The court considered whether the expert's valuation was conducted in accordance with the agreement and whether it was made on the merits. The court also assessed the plaintiff's argument that the expert acted with partiality, potentially warranting the setting aside of the valuation. The court referred to previous cases, including Collier v Mason, Legal & General Life of Australia Ltd v A Hudson Pty Ltd, Holt v Cox, and Beevers v Port Phillip Sea Pilots Pty Ltd, to determine the principles of apprehended bias and impartiality in expert valuations.

Justice Byrne held that the expert's valuation did not comply with the terms of the agreement and was not made on the merits. However, the court found that the expert's failure to act impartially did not warrant setting aside the valuation, as the plaintiff had not demonstrated a real prospect of success in establishing apprehended bias. The court granted summary judgment to the defendant and refused leave to appeal.
