Comparing the Prospective Effect of Judicial Rulings Across Jurisdictions

Overruling of earlier decisions, when it occurs, operates retrospectively with the effect that it infringes the principle of legal certainty through upsetting any previous arrangements made by a party to a case under long standing precedents established previously by the courts. On this account, in the recent past, a number of jurisdictions have had to deal with the prospect of introducing in their own systems the well-established US practice of prospective overruling whereby the court may announce in advance that it will change the relevant rule or interpretation of the rule but only for future cases. However, adopting prospective overruling raises a series of issues mainly related to the constitutional limits of the judicial function coupled by the practical difficulties attendant upon such a practice. This book answers a number of the questions raised by this practice. It makes use of the great reservoir of foreign legal experience that furnishes theoretical and practical ideas from which national judges may draw their knowledge and inspiration in order to be able to advise a rational method of dealing with time when they give their decisions.
