Importance of judicial decisions as a perceived level of relevance

Abstract

Studies employing network analysis to reveal hidden mechanisms in judicial decision making, both in common law as well as civil law countries often use rather vague concepts of ‘importance’ of judicial decisions, concepts that are not always thoroughly explained, tend towards certain relativity and are used together with other similar words [(legal) relevance, (legal) significance…], with or without attempting explanation of these concepts, or relying purely on operationalization. This paper argues that in the context of legal systems that do not recognize a doctrine of precedent this approach is either oversimplified, or even erroneous. It further shows that ‘importance’ of past case-law is essentially a matter of the judge’s choice. Approaching this concept in this manner allows me to show that this choice is explainable within the theoretical framework provided by theories of relevance. This paper focuses on two major approaches to relevance: linguistic pragmatism and information retrieval, and shows that the concept of optimal relevance, as understood by theories of relevance, may serve well as an underlying explanatory framework for answering the question of why judges tend to argue by referring to past case-law even in those legal systems that do not recognize a doctrine of binding precedent.
