Graham v Paterson

The Supreme Court of New South Wales considered a dispute between Graham and Paterson concerning the constitutional validity of certain provisions of the *Motor Vehicles (Third Party Insurance) Act 1942* (NSW). The applicant, Graham, challenged the Act's requirement for compulsory third-party motor vehicle insurance, arguing it infringed upon the freedom of inter-State trade and commerce guaranteed by section 92 of the Australian Constitution.

The central legal issue before the Court was whether the compulsory insurance scheme imposed by the *Motor Vehicles (Third Party Insurance) Act 1942* (NSW) constituted an impermissible burden on inter-State trade and commerce, thereby contravening section 92 of the Constitution. Specifically, the Court had to determine if the Act's provisions, which mandated that all motor vehicles operating within New South Wales be insured with the Government Insurance Office of New South Wales, placed an undue restriction on the ability of individuals and businesses to engage in inter-State trade and commerce.

The Court reasoned that section 92 of the Constitution, while protecting inter-State trade and commerce from discriminatory burdens, did not confer an absolute right to conduct such trade free from all regulation. It held that the compulsory insurance scheme was a valid exercise of the State's power to regulate for the safety and welfare of its citizens, including ensuring compensation for victims of motor vehicle accidents. The Court found that the scheme did not discriminate against inter-State commerce, nor did it impose a tax or charge that was prohibitory in nature or that unduly restricted the movement of goods or persons across State borders. The requirement for insurance was seen as a reasonable regulatory measure applicable to all vehicles operating within the State, regardless of their origin.

The Court accordingly dismissed the application, upholding the constitutional validity of the *Motor Vehicles (Third Party Insurance) Act 1942* (NSW).
