Wyllie v Tarrison Pty Ltd

Wyllie and Tarrison Pty Ltd were parties to litigation concerning a contract for the sale of an aircraft. The dispute involved whether a new purchaser had been substituted for the original purchaser, thereby discharging the guarantor of the original purchaser's obligations. The matter was heard on appeal.

The court was required to determine several legal issues. These included whether the contract of sale had been novated, effectively substituting a new purchaser for the original one. Further, the court had to consider whether the obligations of the guarantor of the original purchaser were discharged as a result of this alleged novation or substitution. The construction of the contract, particularly in light of its commercial purpose, was central to these determinations. Additionally, the court was asked to interpret the meaning of "serviceable condition" in the context of an aircraft sale, and to consider claims of misleading and deceptive conduct in relation to oral representations about the aircraft's condition.

The court reasoned that the express terms of the contract, when read in light of its commercial purpose and context, did not support the contention that a novation had occurred. Where ambiguity existed in the express terms, the court considered the commercial purpose to ascertain the parties' intentions. The court found that the term "serviceable condition" was to be interpreted in accordance with the commercial realities of aircraft sales, rather than a strict, technical definition. The court also addressed the claims of misleading and deceptive conduct, applying the relevant provisions of the *Trade Practices Act 1974* (Cth) and the *Fair Trading Act 1987* (NSW).

The appeal was dismissed, and the appellant was ordered to pay the costs of the appeal.
