"In 1978 the Pearson Commission in the United Kingdom rejected a no-fault system in dealing with clinical negligence. While declaring the existing tort system as costly, cumbersome, prone to delay, and too capricious in its operation to be defensible, the commission rejected no-fault compensation on grounds of the difficulty in overhauling the tort liability system and the perceived difficulties in causation judgments. A general conservatism in the legal profession and opposition from the insurance industry were other factors. Much has changed in the NHS since then."
