The respondent's husband died during a follow-up angiogram as part of a clinical trial.
The respondent sued the principal investigator, Dr. Strauss, for negligence and breach of fiduciary duty.
The jury found breach of standard of care but no causation in negligence.
The trial judge found breach of an ad hoc fiduciary duty and awarded damages, stating causation was removed from the analysis in the fiduciary context.
The Court of Appeal allowed the appeal, holding that the trial judge erred by not examining causation in the fiduciary context.
The Court found no causal link between the alleged fiduciary breach and the loss, relying on the jury's finding on causation in the negligence claim, as the claims were based on substantially the same conduct.
The action was dismissed.
