Nathan Ltd v Rossington Holdings Pty Ltd

Nathan Ltd appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the interpretation of a clause within a commercial lease agreement between Nathan Ltd, as the landlord, and Rossington Holdings Pty Ltd, as the tenant. The core of the disagreement lay in whether a specific renovation undertaken by the tenant constituted a "structural alteration" as defined by the lease.

The Court of Appeal was required to determine whether the tenant's alterations to the leased premises, which involved the removal of internal walls and the installation of new partitions, amounted to structural alterations within the meaning of clause 10(a) of the lease. This clause stipulated that the tenant could not make structural alterations without the landlord's prior written consent. The primary legal issue was the proper construction of the term "structural alteration" in the context of the lease agreement and relevant common law principles.

The Court analysed the lease agreement and considered the ordinary meaning of "structural alteration," referencing established legal principles regarding lease covenants. It found that the alterations made by Rossington Holdings, while significant, did not affect the essential load-bearing elements or the fundamental integrity of the building's structure. The court reasoned that the term "structural alteration" typically refers to changes that affect the foundations, walls, roof, or other primary load-bearing components of a building. The internal modifications, in this instance, were deemed to be non-structural in nature, relating to the internal layout and fit-out of the premises rather than the building's fundamental structure.

The appeal was dismissed, with the Court of Appeal affirming the Supreme Court's finding that the alterations did not constitute a breach of the lease covenant.
