Tantum habent de lege, quantum habent de justitia is a Latin legal maxim that means precedents have value in the law to the extent they represents justice. Precedents are given value by courts because it establishes a rule or principle that other courts use in subsequent cases. Precedents are considered to have binding effect or persuasive effect. However, a wrong case law cannot be followed in a subsequent case. A decision is considered as a wrongful decision when the decision makers reach the conclusion wrongfully or if the decision is made beyond the rights granted by statutes or the constitution.
