Tinworth v Insurance Australia Limited

This case concerned an application for special leave to appeal to the High Court of Australia. The applicant, Steven James Tinworth, sought leave to appeal against a decision of the Queensland Court of Appeal which had overturned a finding of negligence in his favour. The dispute arose from a motor vehicle accident where the applicant, standing by the side of the road, was struck and injured by a vehicle that had departed the carriageway. The applicant contended that the driver of the vehicle, Mr Haydon, was negligent in his driving, leading to the accident.

The primary legal issue before the High Court was whether a plaintiff injured in a road traffic accident must prove the specific speed at which a negligent driver ought to have been travelling to avoid a collision in order to recover damages. This question was framed by the applicant as a point of law concerning the evidentiary requirements for establishing causation in negligence claims involving excessive speed, particularly where the accident involved aquaplaning. The applicant argued that the majority of the Court of Appeal erred in requiring expert evidence to establish the speed at which the vehicle could have safely traversed the water, thereby creating an overly stringent evidentiary burden.

The High Court considered the arguments regarding the necessity of proving a specific safe speed. The applicant, through counsel, argued that the dissenting judgment in the Court of Appeal, which found negligence and causation based on common sense and the unreasonableness of the speed in the prevailing conditions, represented the correct approach. This approach suggested that if a reasonable speed had been adopted, the accident would likely have been avoided. Conversely, the respondent argued that the case turned on its specific facts and the lack of evidence to establish causation. They contended that the plaintiff had failed to prove that a different speed would have prevented the aquaplaning and subsequent loss of control, and that the conditions on the road were dynamic and unpredictable, making it difficult to establish negligence and causation without expert evidence.

The High Court ultimately granted special leave to appeal, indicating that there was a sufficient question of law or public importance to warrant further consideration. The specific orders regarding the scope of the appeal, including whether it would extend to issues of contributory negligence and quantum, were to be determined at a later stage.
