Rumblings from Olympus: Das Zeitelement in der (Fort-)Bildung des englischen common law

In this article, I endeavour to render an account of various temporal aspects of judicial decision making: the judicial anticipation of future statutory reform, the retrospective effects of judicial decisions, and the possibility of rulings that have exclusively prospective effects (so-called »prospective overruling«). All three aspects are interconnected through their respective links to the same theoretical and constitutional themes – most importantly, the problem of reconciling the function of adjudication first with the constitutional principle of parliamentary sovereignty in a common law system, and second with the theoretical explanation of the decision-making process as the creation of law within the boundaries of precedent and legal principle. Since the days of Bentham's polemics, the specifically temporal implications of these classic problems of common law theory have been discussed. However, unlike some Continental jurisdictions, as Lord Rodger of Earlsferry pointed out, England and Wales never developed a comprehensive discourse on matters concerning the relationship between law and time; instead, temporal aspects have, in a more pointillist and haphazard fashion, been treated in the context of the various discussions surrounding the abovementioned fundamental problems. Different aspects have received different degrees of attention: whereas the anticipation of statutes through judge-made law has been discussed only rarely, a much larger number of judicial and scholarly comments exist with regard to the questions of adjudicatory retrospectivity and the possibility of prospective overruling. While traditionally the retrospective effects of judgements have been accepted and explained as being inherent in the nature of the adjudicative process, only recently, in 2005, did the House of Lords make clear that it lays claim to the constitutional power to issue non-retrospective rulings, and that neither the nature of judicial decision making nor the principle of parliamentary sovereignty would stand in the way of thus employing the technique of prospective overruling.
