Prowl Pty Ltd v DL Brookvale Pty Ltd

Prowl Pty Ltd commenced proceedings against DL Brookvale Pty Ltd in relation to the sale of a property. The primary dispute was whether the purchaser was required to pay the vendor the amount of GST payable by the vendor in respect of the taxable supply of the property. The case was heard in the Supreme Court of New South Wales. The legal issues before the court included the interpretation of the contract terms regarding the GST and whether there was a common mistake by the parties in relation to the GST obligation.

The court examined the contract language and the context in which it was used, considering whether the terms "inclusive" and "exclusive" of GST were clear and unambiguous. It was determined that the contract did not require the purchaser to pay the GST. The court also considered extrinsic evidence, including prior negotiations between the parties, to understand the common intention of the parties at the time of the contract. The court found that the parties had a common intention that was not accurately reflected in the contract, leading to a rectification of the contract. The court concluded that the purchaser was not required to pay the GST and that the contract should be rectified to reflect the parties' true intentions.

The Supreme Court of New South Wales ordered that the contract be rectified to remove the requirement for the purchaser to pay the GST. The court also determined that Prowl Pty Ltd was entitled to rectification of the contract based on the common intention of the parties. The final orders included the rectification of the contract to accurately reflect the parties' intentions and a declaration that Prowl Pty Ltd was not required to pay the GST to DL Brookvale Pty Ltd.
