Case-law Judgments of the Court of Justice of the European Union contribute to a body of caselaw, creating precedents to how future similar cases should be resolved (i.e. future legal interpretation and court cases should follow the argumentation and logic from previous case-law), at least until they are overridden by new case-law, new legislation or a treaty change (Court of Justice of the European Union 2014; Greer et al. 2014).
