Case law is a general term for body of cases decided by the courts and other persons or bodies performing judicial functions. Commentators write that case law is distinguished from statute law in that the latter is a norm of conduct promulgated by the law-making authorties of a state while case law is the same norm proclaimed by judicial authorities.
Case law may be categorized into (1) conventional decision which cover all rulings by regularly or specially constituted courts of justice, and (2) subordinate decisions which include all rulings by administrative and legislative tribunals.Hierarchy of the Courts
