Collier & Anor v NRMA Insce Ltd

The applicants, Collier and another, brought proceedings against the respondent, NRMA Insurance Ltd, in the High Court of Australia. The dispute concerned the interpretation of a motor vehicle insurance policy and whether it provided cover for damage sustained by the applicants' vehicle when it was being driven by a person who was not named on the policy.

The central legal issue before the High Court was whether the policy's clause requiring the driver to be a "named driver" or a "nominated driver" meant that cover was excluded if the vehicle was driven by any other person, or if it merely required that the driver be either named or nominated. The applicants contended that the clause was ambiguous and should be interpreted in a way that provided cover, while the respondent argued for a narrower interpretation that excluded cover.

The High Court, in a joint judgment, considered the principles of contractual interpretation, particularly in the context of insurance policies. Their Honours found that the language of the clause was not ambiguous and clearly stipulated that the driver must be either a named driver or a nominated driver for the policy to be effective. The court reasoned that to interpret the clause otherwise would be to rewrite the contract and ignore the plain meaning of the words used. The principle applied was that clear and unambiguous contractual terms should be given their ordinary and natural meaning.

Consequently, the High Court dismissed the applicants' appeal, upholding the decision of the lower court. The court found that the damage to the vehicle was not covered by the insurance policy as it was being driven by a person who was neither a named nor a nominated driver.
