Grounds of appeal
[14] The appellant contends that the primary judge erred in finding that the respondent had discharged the onus of establishing the matters required under the relevant provision.
[15] It was submitted that his Honour failed to give adequate weight to the evidence of the second witness, and that the findings of fact were not reasonably open on the material before the Court.
[16] The respondent, for its part, submits that no error is disclosed, and that the conclusions reached were well within the range of outcomes available to the primary judge.
Consideration
[17] It is convenient to deal first with the question of construction, as the resolution of that issue informs the remaining grounds advanced by the appellant.
[18] For the reasons that follow, we are of the view that the appeal should be allowed in part and the matter remitted for further determination.

CaseChat Overview and Summary
In the matter of Yu v Yu, the plaintiff sought to set aside a property settlement agreement on the basis of a common mistake. The agreement had been made between the plaintiff and the defendant, who were married and subsequently divorced. The court was required to determine whether the agreement could be set aside due to a common mistake that was fundamental to the agreement. The court also needed to address the jurisdictional scope of equity to intervene in such cases.
The court found that there was no fundamental misapprehension shared by both parties that was central to the agreement. Consequently, the agreement could not be set aside on the basis of a common mistake. The court examined the circumstances of the case to determine whether there was a common misapprehension that was fundamental to the agreement. The court concluded that there was no such misapprehension, and therefore the agreement could not be set aside. The court also considered the jurisdictional scope of equity to intervene in such cases and found that it did not apply in this instance.
The court held that the agreement was valid and enforceable and could not be set aside on the grounds of a common mistake. The court found no issue of principle in the other areas of law raised by the parties, including res judicata and cause of action estoppel, illegality, implied terms, and construction of the contract.
The court dismissed the plaintiff's claim and made no orders.
