The facts
2 In March 1993 Mark Maddison was the registered owner of a Ford Falcon motor vehicle in relation to which he held a policy of insurance issued by GIO. Pursuant to the policy GIO was obliged to indemnify him in relation to certain defined events. The first such event is identified in the policy as "Defined Event A" and relates to legal liability incurred for loss of or damage to property (other than the insured vehicle) occurring as a result of the use of the vehicle. The indemnity so afforded extended to legal liability incurred by any person besides Maddison who, at the time of incurring the liability, was in charge of the vehicle with Maddison's express or implied consent. "Defined Event B" is of no present relevance. "Defined Event C" relates to loss of or damage to Maddison's own vehicle.
3 The policy specifically excluded indemnity for liability incurred by a person who at the time the liability was incurred was not licensed to drive. The exclusion was itself subject to a qualification and did not apply to loss or damage to the insured vehicle, or to legal liability incurred by Maddison when the vehicle was being driven by an unlicensed driver unless Maddison knew or should reasonably have known that the driver was unlicensed.
4 On 1 March 1993 Maddison's vehicle was being driven by Schmitzer with Maddison's authority. Schmitzer held no licence to drive. The vehicle collided with and caused damage to a vehicle owned by Ward in circumstances that made Schmitzer liable for that damage. Maddison's vehicle was also damaged in the collision. The damage to Maddison's vehicle came within the policy provisions as Defined Event C. He made a claim on the policy and GIO met the claim.
5 Ward commenced proceedings against Schmitzer, claiming reimbursement for the costs of repairing the damage to its vehicle. Schmitzer did not defend the claim and default judgment was entered against her. She too made a claim on the policy, relying on the extended cover provided in relation to Defined Event A to persons other than the policy holder. GIO declined to indemnify her on the basis that she was an unlicensed driver and therefore came within the exclusion referred to above. It may here be mentioned that the claims made by Maddison and Schmitzer were made jointly in a single claim form.
6 It is to be observed that the qualification on the exclusion has no present relevance or application. It applies to loss of or damage to the insured vehicle (that is, Maddison's Ford Falcon) or to the incurring of a legal liability by the policy holder (that is Maddison). It does not prevent application of the exclusion in relation to liability incurred by unlicensed drivers. The exclusion has the effect that an unlicensed driver, even one who has the authority of the owner of the vehicle to drive it, is not entitled to indemnity under the policy. The qualification is intended to protect the position of a policy holder who in good faith authorises the use of the insured motor vehicle by a person who is, without the actual or constructive knowledge of the policy holder, unlicensed; it is not designed or intended to afford cover to an unlicensed driver; indeed it is designed and intended to do precisely the opposite, that is to maintain the exclusion in relation to unlicensed drivers, whilst deflecting its impact on an innocent policy holder.
