Why are precedents important?

• A. So that the law can develop in a consistent and coherent fashion.
• B. Old cases retain authority and their decisions can be used as the basis for decisions.
• C. They require judges to be creative in every case.
• D. They replace statutes as the primary source of law.

Answer: (A)

Precedents are important because they create a framework for how the law develops over time. The principle of stare decisis means courts look to prior decisions when handling similar disputes, so outcomes in new cases are consistent with established results. This consistency helps people and lawyers predict how laws will be applied and promotes fairness, since like cases are treated alike. Precedents also let the law evolve gradually, with higher courts refining or adjusting past rulings when necessary rather than making abrupt shifts.

While previous cases do carry authority and can guide future decisions, the key purpose is to ensure the legal system remains predictable and coherent. Precedents do not replace statutes as the primary source of law; statutes are still the foundation, and case law interprets and applies them. Precedents also don’t require judges to be creative in every case; they often constrain reasoning to maintain consistency across decisions.
