New South Wales Land and Housing Corporation v Diab

The New South Wales Land and Housing Corporation (the Corporation) sought leave to appeal from a decision of the Civil and Administrative Tribunal of New South Wales (NCAT) concerning a residential tenancy dispute. The core of the dispute involved the Corporation's retrospective cancellation of rental rebates and its subsequent attempt to terminate the tenancy agreement on the basis of non-payment of these rebates. The Corporation appealed to the Court of Appeal of New South Wales.

The primary legal issues before the Court of Appeal were whether the grant of rental rebates constituted variations to the residential tenancy agreement under the *Residential Tenancies Act 2010* (NSW), and consequently, whether the Corporation was entitled to terminate the tenancy agreement due to the tenant's alleged non-payment of these retrospectively cancelled rebates, particularly in light of section 57 of the *Housing Act 2001* (NSW).

The Court of Appeal, comprising Beazley P, Macfarlan and Leeming JJA, ultimately dismissed the Corporation's appeal. While leave to appeal was granted, the Court found that the Corporation's arguments lacked merit. The Court's reasoning, though not detailed in the provided text, appears to have concluded that the retrospective cancellation of rebates and the subsequent attempt to terminate the tenancy on that basis were not legally sustainable. The Court applied principles of administrative and contract law relevant to residential tenancies and government housing schemes.

The Court of Appeal ordered that the appeal be dismissed with costs.
