In effect, Jurisprudence is based on primary rules which actually define acceptable and unacceptable conduct in a social system and secondary rules which tell law officials how to use the primary rules. There are further subdivisions of secondary rules which include the rules of adjudication, the rules of change, and the rules of recognition. In these, the rules of adjudication show ways in which the jurisprudence governs the resolution of legal disputes. The rules of change govern how laws can be altered while the rules of recognition allow rules to be considered valid or invalid.
