The appellant, Dr. Colin Ward, appealed a trial judgment finding him liable for negligence in performing a laparoscopic colectomy on the respondent, Karen Armstrong, in February 2010.
The trial judge found that Dr. Ward breached the standard of care by bringing a LigaSure device within one to two millimetres of the respondent's left ureter, causing a thermal injury that resulted in stricturing of the ureter and eventual removal of the kidney.
The majority of the Court of Appeal (Paciocco and Juriansz JJ.A.) allowed the appeal, finding that the trial judge erred in law by defining the standard of care as a goal or result (avoiding injury) rather than as the means a prudent surgeon would employ.
The majority held that since the trial judge found Dr. Ward took the steps a prudent surgeon would take, he should have been exonerated.
Van Rensburg J.A. dissented, finding the trial judge's findings on standard of care were fully supported by the evidence and that staying at least two millimetres away from the ureter was a necessary step, not merely a goal.
