Clark v Ryan [1960] HCA 42

Clark v Ryan [1960] HCA 42

By majority, Mr. Foster Joy's evidence went beyond admissible expert evidence: he lacked relevant expert qualifications in the field needed to explain the behaviour of the semi-trailer and he gave opinions on matters the jury could determine for themselves or opinions outside any demonstrated expertise. Because the evidence was pressed and admitted over objection, was intended to influence the jury on liability, and could not be said to have had no material effect on the verdict, the defendant's prima facie entitlement to a new trial was not displaced.

Procedural Posture

Appeal in Negligence Action for Damages for Personal Injury From Motor Vehicle Collision / High Court Appeal From Order of the Supreme Court of New South Wales Dismissing the Defendant's Application for a New Trial

Legal Issues

  1. 1 ['Whether the opinion evidence of Mr. Foster Joy about the behaviour and causes of the jack-knifing of a semi-trailer was admissible as expert evidence.' 'Whether Mr. Foster Joy was sufficiently qualified to give the opinion evidence admitted at trial.' 'Whether the erroneous admission of inadmissible opinion evidence required the verdict to be set aside and a new trial ordered.']

Ratio Decidendi

By majority, Mr. Foster Joy's evidence went beyond admissible expert evidence: he lacked relevant expert qualifications in the field needed to explain the behaviour of the semi-trailer and he gave opinions on matters the jury could determine for themselves or opinions outside any demonstrated expertise. Because the evidence was pressed and admitted over objection, was intended to influence the jury on liability, and could not be said to have had no material effect on the verdict, the defendant's prima facie entitlement to a new trial was not displaced.

Court Disposition

Appeal allowed; verdict set aside and new trial ordered.

Orders

  • ['Appeal allowed with costs.' 'Order of the Supreme Court of New South Wales discharged.' 'In lieu thereof order that the appeal to that Court be allowed with costs, the verdict of the jury set aside and a new trial be had: the costs of the former trial to abide the event.']
