RUGS-A-MILLION (WA) Pty Ltd v Walker

In the case of RUGS-A-MILLION (WA) Pty Ltd v Walker, the plaintiff sought a declaration from the court that the conduct of the Commissioner of Fair Trading was not authorised by the Consumer Affairs Act 1971 (WA). The plaintiff argued that the powers of the Commissioner under section 19 of the Act did not extend to the investigation of complaints under section 17, nor did they apply in connection with the powers of the Commissioner to institute legal proceedings under the Fair Trading Act 1987 (WA). The court was tasked with determining the extent of the Commissioner's powers under section 19 of the Consumer Affairs Act and whether those powers were limited to specific duties imposed by statute.

The court considered the argument that section 19 of the Act must be interpreted in light of the presumption that statutory provisions do not abrogate important common law rights without clear words or a necessary implication to that effect. The plaintiff's counsel referred to previous cases, including The Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission and George v Rockett, to support the argument that the reference to "duties" in section 19(1) should be read narrowly, excluding functions or powers conferred on the Commissioner by statute. The court also examined the definition of "functions" in section 5 of the Interpretation Act 1984 (WA), which includes "powers, duties, responsibilities, authorities, and jurisdictions," and noted that there was nothing in the Consumer Affairs Act that would suggest a different interpretation of "functions" or "duties."

The court further considered whether the provisions of the Fair Trading Act, which confer powers on the Commissioner, were relevant to section 19 of the Consumer Affairs Act. The plaintiff argued that these provisions did not impose any duty on the Commissioner within the meaning of section 19(1) of the Consumer Affairs Act, as they simply confer on the Commissioner a power to prosecute for offences under the Fair Trading Act. The court had to determine whether these powers, which are not duties, were included within the scope of the Commissioner's functions under section 19 of the Consumer Affairs Act.

The court found in favour of the plaintiff, ruling that the powers of the Commissioner under section 19 of the Consumer Affairs Act were limited to specific duties imposed by statute and did not extend to the functions conferred by other statutes such as the Fair Trading Act. The court declared that the conduct of the Commissioner was not authorised by the Consumer Affairs Act in relation to the investigation of complaints and the powers to institute legal proceedings under the Fair Trading Act. The court's decision clarified the scope of the Commissioner's powers under the Consumer Affairs Act and ensured that statutory provisions were not interpreted to abrogate common law rights without clear statutory language.
