On 25 January 2016, the Judicial Committee of the Privy Council handed down judgment in the case of Williams v The Bermuda Hospitals Board  UKPC 4, the most recent reported decision of the highest appellate Court regarding material contribution in clinical negligence cases.
The Privy Council upheld the Bermuda Court of Appeal’s decision that a negligent delay to diagnose and treat its patient “materially contributed to the process, and therefore materially contributed to the injury to the heart.” Since there had been a material contribution, causation was established.
