This contribution proposes a novel approach, which combines traditional legal analysis with the use of a quantitative method, to analyse the standards employed in case law in a given area. The goal of our Data-Based Case Law (DBCL) is determining the meaning of relations between standards (considered in pairs) and appreciating the statistical significance of the resulting relations. We submit that this combined approach may be employed in any area of the law where there is a substantial body of judicial decisions. We demonstrate the functioning of our DBCL in relation to copyright law in the European Union (EU). Copyright has been subject to a limited harmonisation of the laws of individual EU Member States.
