The plaintiffs, twin brothers born prematurely who developed cerebral palsy, sued their mother's obstetrician for negligence.
The trial judge found the obstetrician breached the standard of care by failing to assess the mother when she reported leaking fluid, resulting in a failure to administer a full course of antenatal corticosteroids (ACS).
The trial judge concluded this failure caused the twins' cerebral palsy and awarded damages.
The obstetrician appealed the causation finding.
The Court of Appeal dismissed the appeal, with the majority holding that the trial judge made no palpable and overriding error in applying a robust and pragmatic approach to the expert evidence and concluding that the failure to administer ACS caused the injuries.
