Care and concern for the elderly have long been regarded by social anthropologists as hallmarks of a civilised community. Unfortunately the care of the elderly frequently presents problems of both a social and legal nature. Some of the difficulties which confront legal practitioners arise from factual situations similar to the following: an aged, widowed father, whose health is deteriorating, asks his adult child to move into his house and look after him for the rest of his days. In return, the father promises orally to leave the house by will to the child or to the child and his or her spouse. The type of problem which can then occur is seen when it is found on the father's death either that he has died intestate, and the estate of which the house forms part has to be divided equally between the child and his or her brothers and sisters, or that he has forgotten to alter his last will. Consequently a will executed perhaps many years earlier provides that the house should be left to some other relative—or even to the legendary cats' home. The child, having assiduously cared for the elderly father, may wish to claim the house and may seek the practitioner's advice.

On 14 August 1988 the death occurred of Miss Pamela Banyard of Laxenheath. She had been the victim eighteen months previously of a savage and brutal attack for which her assailant was sent to prison for ten years on conviction of attempted murder and robbery. Why was he not convicted of murder? The answer in the words of the Crown Prosecutor: “We cannot prosecute for murder as she died more than a year and a day after the attack.”

I Propose to begin with a word or two about the growth of Appeals and then to say something about the present appellate jurisdictions in this country. I suppose, speaking generally, the man who has a decision given against him has a disposition to be discontented with it, and tries to get another decision if he is satisfied that he is in the right. But I should imagine also that in early days the private litigant had a very small say in the matter whether he should, or should not, have the right of appeal. Before the Judiciary and the Executive were distinguishable, when the act of deciding disputes was an act of government, ordinarily performed by the Chieftain or Ruler though perhaps sometimes delegated to a subordinate, in those days, of course, the judge, being also ruler, there were no appeals, and one can only hope that decisions were satisfactory to everyone concerned. Whether the same persons made good rulers and good judges in the days of the Hebrew Judges I do not know; but I do know that I should be very sorry indeed if the two functions, which are of entirely different kinds, were united nowadays. As soon as a ruler began to delegate his function to a subordinate there can be no question that he would from time to time desire to revise the decisions that were arrived at, partly from self-interest, and partly, one may assume, from a sense of justice, knowing that, or thinking that, the decision was wrong and that he could give a better one. And in that kind of way there would gradually emerge a more or less settled system by which decisions would become the subject of review.

In Kleinwort Benson v. Lincoln City Council [1998] 3 W.L.R. 1095 the House of Lords heard consolidated appeals arising out of the failure of interest rate swap transactions entered into between various banks and local authorities. Having paid out considerable sums under the swap arrangements, the banks were disconcerted to find them declared ultra vires and void (Hazell v. Hammersmith and Fulham L.B.C. [1992] 2 A.C. 1). The Lords have now held that sums paid by the banks may be recovered back, by action in restitution for mistake. In so holding, they have abrogated the rule that a mistake of law is not actionable, and denied (at least on these facts) any defence that the parties acted on the basis of “settled law”.
