New Britain Plantations Limited v Acting Treasurer of the Territory of New Guinea

This case concerned an appeal to the High Court of Australia from the Supreme Court of the Territory of New Guinea. The appellant, New Britain Plantations Limited, sought to challenge a decision regarding stamp duty payable on an instrument of transfer for land. The dispute arose from the interpretation of the Stamp Duties Ordinance 1927-1933 (N.G.) and its application to a series of land sales, some of which occurred before the ordinance commenced.

The central legal issues before the court were whether an instrument of transfer, executed after the commencement of the Stamp Duties Ordinance 1927-1933 (N.G.), was liable for stamp duty in respect of considerations for sales of land that had been contracted for before the ordinance came into effect. Furthermore, the court had to determine the total amount of duty with which the instrument was chargeable, given that it effectuated multiple antecedent sales.

The court reasoned that the Stamp Duties Ordinance 1927-1933 (N.G.) imposed a charge on instruments of conveyance or transfer executed after its commencement. Section 6 of the ordinance established the general charge, while section 15 provided an exemption only for instruments executed before the ordinance's commencement. Section 37(3) clarified that every sale of real property was chargeable with ad valorem duty upon the consideration, and this duty was to be paid on the conveyance giving effect to the sale. The court held that the instrument of transfer, having been executed after the ordinance commenced, was dutiable. It further determined that the ordinance was not retrospective in operation, as the duty was levied on the instrument itself, even if the calculation of that duty referred to antecedent sales. Therefore, the instrument was chargeable with duty calculated on all three considerations for the sales it effectuated.

The appeal was dismissed with costs, affirming the decision of the Supreme Court of the Territory of New Guinea.
