A view from the High Court of Australia. Mason J said,

’19. I do not doubt that there are some cases in which an ultimate court of appeal can and should vary or modify what has been thought to be a settled rule or principle of the common law on the ground that it is ill-adapted to modern circumstances. If it should emerge that a specific common law rule was based on the existence of particular conditions or circumstances, whether social or economic, and that they have undergone a radical change, then in a simple or clear case the court may be justified in moulding the rule to meet the new conditions and circumstances. But there are very powerful reasons why the court should be reluctant to engage in such an exercise. The court is neither a legislature nor a law reform agency. Its responsibility is to decide cases by applying the law to the facts as found. The court’s facilities, techniques and procedures are adapted to that responsibility; they are not adapted to legislative functions or to law reform activities. The court does not, and cannot, carry out investigations or enquiries with a view to ascertaining whether particular common law rules are working well, whether they are adjusted to the needs of the community and whether they command popular assent. Nor can the court call for, and examine, submissions from groups and individuals who may be vitally interested in the making of changes to the law. In short, the court cannot, and does not, engage in the wide-ranging inquiries and assessments which are made by governments and law reform agencies as a desirable, if not essential, preliminary to the enactment of legislation by an elected legislature…
20. These considerations must deter a court from departing too readily from a settled rule of the common law and from replacing it with a new rule. Certainly, in this case they lead to the conclusion that the desirability of departing from the rule in Searle v. Wallbank is a matter which should be left to Parliament. It is beyond question that the conditions which brought the rule into existence have changed markedly. But it seems to me that in the division between the legislative and the judicial functions it is appropriately the responsibility of Parliament to decide whether the rule should be replaced and, if so, by what it should be replaced. The determination of that issue requires an assessment and an adjustment of the competing interests of motorists and landowners; it might even result in one rule for urban areas and another for rural areas. It is a complicated task, not one which the court is equipped to undertake. ‘
