Guang Dong Zhi Gao Australia Pty Ltd v Fortuna Network Pty Ltd

The dispute between Guang Dong Zhi Gao Australia Pty Ltd and Fortuna Network Pty Ltd was heard by the Australian court, where the plaintiffs sought to enforce a deed of release executed by the defendant. The crux of the matter lay in determining whether the deed was valid and binding as a written contract or if it could be construed as a partly written and partly oral agreement. Additionally, the court had to consider whether the defendant could have the deed set aside or varied under section 87 of the Trade Practices Act, and whether estoppel principles could be invoked.

The primary legal issues revolved around the formal validity of the deed, the interpretation of whether it was entirely a written document or partly written and partly oral, and the applicability of estoppel principles. The court examined the mode of execution of the deed, the presence of signatures, and the context in which the deed was executed to determine its enforceability. Furthermore, the court needed to decide if the alternative argument that the deed could be treated as a binding and enforceable agreement despite formal deficiencies was tenable.

After evaluating the evidence and arguments presented, the court concluded that the deed in question was not validly executed as a deed due to formal defects. However, it found that the agreement could still be enforceable as a partly written and partly oral contract. The court held that the principles governing whether an agreement is wholly in writing or partly in writing and partly oral depend on the context and the intentions of the parties. The court further determined that the defendant was not entitled to have the deed set aside or varied under section 87 of the Trade Practices Act and that estoppel principles did not apply in this case.

The final orders of the court required the defendant to honour the terms of the agreement as a binding contract, despite the formal defects in the execution of the deed. The court rejected the defendant's claim for relief under section 87 of the Trade Practices Act and did not find estoppel applicable to the circumstances of the case.
