Johnson v American Home Assurance Co

In *Johnson v American Home Assurance Company*, the High Court of Australia considered an appeal concerning an insurance policy. The dispute centred on whether the insured had suffered a "permanent total loss of use of one limb," specifically his foot, as defined by the policy. The insurer contended that the insured's ability to use his foot, even with orthotic aids, meant the loss was not total.

The primary legal issue before the court was the construction of the insurance policy, particularly the phrase "permanent total loss of use of one limb." The court had to determine whether the use of orthotic devices to mitigate pain and facilitate function negated a finding of "total" loss of use of the foot. The insured argued that the loss should be assessed based on the practical and effective use of his foot as a foot, asserting that the use of orthotics was irrelevant to this assessment.

The High Court, affirming the Full Court's decision, reasoned that the policy's requirement of "total" loss necessitated considering the actual functional capacity of the insured's foot. The court found that the insured's ability to walk, stand, bear weight, and squat, even with the assistance of orthotics, demonstrated that he retained practical use of his foot. The court held that the use of orthotics was akin to using analgesics to manage pain and did not render the residual use of the foot insignificant. Therefore, the loss of use was not "total" within the meaning of the policy. The appeal was dismissed with costs.
