Barport Pty Ltd v Baum

Barport Pty Ltd, the applicant, sought to build a hangar at Sydney Airport against the terms of a restrictive covenant, which was challenged by the respondents, Baum and others. The dispute reached the Supreme Court of New South Wales, where the applicant argued that the covenant was ambiguous and thus unenforceable, and that the respondents were estopped from enforcing it. The respondents contended that the applicant's actions breached the covenant and that they were not estopped from enforcing it. The court was required to determine the meaning of the restrictive covenant, whether estoppel applied, and whether there was any misleading or deceptive conduct.

The court examined the restrictive covenant's language and found that it was clear and unambiguous. The term "height limitations" was defined using dictionary definitions, considering the context of the Civil Aviation Safety Authority Manual of Standards Part 139. The court held that the applicant's hangar, with walls six metres tall, was in breach of the covenant. The court also found that the respondents were not estopped from enforcing the covenant because they did not induce the applicant's assumption, and there was no duty to correct it. Furthermore, the court dismissed the applicant's claim of misleading or deceptive conduct, as there was no reasonable expectation of disclosure under the Competition and Consumer Act 2010.

The court found that the applicant breached the restrictive covenant by constructing the hangar with walls six metres tall, which exceeded the height limitations specified in the covenant. The court also held that the respondents were not estopped from enforcing the covenant, as they did not induce the applicant's assumption and were under no duty to correct it. Additionally, the court dismissed the applicant's claim of misleading or deceptive conduct, finding that there was no reasonable expectation of disclosure. The court allowed the appeal in part to amend the order for clarity, ensuring it affected the correct part of the hangar.

The court ordered that the applicant's hangar, which exceeded the height limitations specified in the restrictive covenant, be demolished within 28 days. The court also ordered that the applicant pay the respondents' costs of the appeal and the proceedings in the lower court. The order was amended to clarify that only the portion of the hangar exceeding the height limitations was to be demolished, and the applicant was granted permission to appeal to the Court of Appeal.
