Tolson v Roncoli

This matter concerned an application for special leave to appeal to the High Court of Australia from a decision of the Full Court of the Supreme Court of South Australia. The applicant, Mrs. Tolson, sought to appeal a finding that the respondent driver, Mr. Roncoli, had not breached his duty of care. The dispute arose from a motor vehicle accident where the respondent, driving on a country road with four passengers, reacted to a noise perceived as a tyre blow-out by inquiring of his passengers and then applying the brakes. This braking action, as found by the trial judge, caused the vehicle to go out of control and overturn, resulting in injuries.

The applicant sought special leave to appeal on three principal grounds. Firstly, the applicant contended that the court needed to determine the role of concepts such as "agony of the moment," "automatism," and "instinctive reaction" in establishing a standard of care, arguing that these concepts should not be treated as distinct from the general principles of negligence. Secondly, the applicant questioned the circumstances under which a Court of Appeal should interfere with a lower court's factual findings, particularly when there is no substantial dispute of fact, and suggested that the Full Court had improperly substituted its own opinion for that of the trial judge. Finally, the applicant argued that the decision of the Full Court, by accepting the driver's instinctive reaction as a defence and placing the driver in a position akin to an automaton, had significant implications for road safety across Australia, given the commonality of such circumstances.

The High Court was asked to consider whether the Full Court erred in finding no breach of duty of care where the driver's actions were an instinctive reaction to a perceived emergency. The applicant argued that the Full Court's approach, which appeared to treat the driver's reaction as a complete defence by analogy to automatism, was an incorrect application of negligence principles. The applicant contended that the trial judge's finding that the braking itself caused the loss of control was crucial and that the Full Court had overstepped its appellate role in re-evaluating this finding. The applicant submitted that the Full Court's decision, if allowed to stand, would create a precedent that could excuse drivers for actions taken in perceived emergencies, regardless of whether those actions were reasonable in the circumstances.
