In common law legal systems, judges are bound by precedent, which means they must follow decisions made in similar cases in the past. Precedent helps ensure consistency and predictability in legal outcomes, promoting fairness and equality before the law. Precedent comes in two forms: binding and persuasive. Binding precedent must be followed by lower courts within the same jurisdiction, while persuasive precedent can be considered and adopted at the discretion of the judge. Over time, a body of case law develops, creating a hierarchy of legal principles that guide decision-making. This system allows for gradual adaptation and evolution of the law to meet changing social norms and values. However, precedent is not inflexible. Judges have the power to distinguish or overrule precedent in cases where it is no longer considered just or relevant. This flexibility allows for the law to remain responsive to changing circumstances and ensures continued development in legal thought. In conclusion, the reliance on precedent in common law systems is a key feature that helps uphold the rule of law and maintain the integrity of the legal system.
