Legal Certainty and Predictability

The aim of the article is to formulate a proposal for the conceptual analysis of the notion of predictability of law, in order to make clear its theoretical and practical implications. To achieve this goal, I will explain the theoretical (what conceptual implications it has) and practical (what decisions it requires us to make) commitments that this conceptualization requires. Specifically, I analyze the commitments to the types of receivers of predictions and issuers of predictions; then I identify what kinds of relationship can be assumed between the predictability of law and its effectiveness; next I indicate what the use of predictions as a means of assessing the degree of satisfaction of legal certainty commits us. Finally I indicate what commitments must be made in adopting a methodology for making predictions.
