Ling Chan v Stuart Wood and Kai Design and Construction Pty Ltd

In this case, Ling Chan sought a declaration that the adjudicator, Stuart Wood, fell into jurisdictional error and that there was an estoppel preventing her from asserting that she intended to live in the property at the time of entering into the contract. The dispute arose out of a construction contract for the building of a dwelling in Harrison, a suburb of Canberra. The case was heard in the Supreme Court of the Australian Capital Territory.

The primary legal issues that the court had to determine were whether Ling Chan intended to reside in the property at the time of entering into the contract and if so, whether that intention rendered the adjudicator's decision invalid. Additionally, the court had to consider whether there was an estoppel in pais preventing Ling Chan from asserting her intention to live in the property. The outcome of these issues would determine whether the adjudicator had jurisdiction under the Building and Construction Industry (Security of Payment) Act 2009 (ACT) (SOP Act) and if the estoppel claim was valid.

The court held that Ling Chan did intend to reside in the property at the time of entering into the contract, which meant that the contract was not one to which the SOP Act applied. Consequently, the adjudicator lacked jurisdiction under the SOP Act, and the adjudication was invalid. The court also found that there was no estoppel preventing Ling Chan from asserting her intention to reside in the property, as there was no reliance on any representation made by her that would give rise to an estoppel. Therefore, Ling Chan was entitled to relief.

The court granted Ling Chan the relief she sought, declaring that the adjudicator fell into jurisdictional error and that there was no estoppel preventing her from asserting her intention to reside in the property.
