Pua Hor Ong v Wu You Yang Pty Ltd

In the case of Pua Hor Ong v Wu You Yang Pty Ltd, the appellants sought to challenge the removal of caveats over several parcels of land by the respondents. The Master of the Supreme Court had previously ruled that the appellants had not established a prima facie case that they held an equitable mortgage over the land, leading to the respondents' successful application to remove the caveats. The appellants appealed this decision, arguing that they could establish a prima facie case and that the balance of convenience favoured maintaining the caveats.

The central legal issues in this appeal were whether the appellants could establish a prima facie case that they held an equitable mortgage over the land and whether, if they did, the balance of convenience favoured retaining the caveats. Additionally, the court examined the construction and interpretation of the interest rate clause in the loan agreement, which was argued to render the agreement uncertain and thus invalid.

The appeal court found that the appellants had indeed established a prima facie case that they held an equitable mortgage over the land. This was based on evidence that the interest rate clause could be interpreted as referring to the median of commercial rates available from Australian banks for a specific period, providing a sufficiently certain formula for determining the interest rate. The court also concluded that it was reasonably arguable that the parties intended to be bound by the agreement even if the interest clause were ineffective. As a result, the balance of convenience favoured maintaining the caveats. The appeal was thus allowed, and the decision of the Master was set aside.

As a result of the appeal being allowed, the original decision of the Master of the Supreme Court was overturned, and the caveats over the land in question were reinstated in favour of the appellants.
