Regina v National Insurance Commissioner, Ex parte Hudson: HL 1972

The House considered whether it would have power to make a ruling with prospective effect only. Lord Diplock said the matter deserved further consideration; Lord Simon said that the possibility of prospective overruling should be seriously considered, but that he would prefer legislation, saying that ‘informed professional opinion’ was probably to the effect that the House had no power to overrule decisions with prospective effect only.
Viscount Dilhorne discussed the freedom if any to overturn a recent case: ‘[I]f the view be that the decision is clearly wrong, it is, I think, easier to decide that a recent case should not be followed than if it is one that has stood for a long time, for if it is in the latter category many may have acted in reliance on it.’
Lord Reid said that the power given to the House by the Practice Statement was to be applied only in a small number of cases in which previous decisions of the House were ‘thought to be impeding the proper development of the law or to have led to results which were unjust or contrary to public policy.’
Lord Diplock said: ‘Section 5 (1946 Act), which contains the general description of and conditions of entitlement to each of the three benefits, avoids the use of the compound phrase ‘personal injury by accident’ which had appeared in successive Workmen’s Compensation Acts since 1897. It is reasonable to suppose that the change in phraseology was deliberate – though there is an isolated lapse into the expression ‘personal injury by accident’ in section 48(2) of the statute.’
