The role of precedent in the legal system is primarily to serve as a guideline for future cases. Precedent, derived from the Latin term "stare decisis," emphasizes that courts should follow previously established rulings when making decisions in subsequent cases that share similar facts or legal issues. This creates consistency and predictability in the law, allowing individuals and entities to understand how legal principles will likely apply to their situations.

By adhering to precedent, the legal system fosters stability and continuity, which are essential for maintaining public confidence in judicial outcomes. It helps to ensure that similar cases lead to similar results, thereby upholding the rule of law. When courts apply precedent, they not only honor past decisions but also facilitate the development of common law over time, influencing how laws are interpreted and applied in an evolving society.

The other options do not accurately represent the role of precedent. While creating new laws is typically the function of legislative bodies, disregarding old laws does not align with the principle of adhering to prior decisions. Ensuring caseworkers follow specific regulations falls outside the scope of how precedent operates within the judicial process.
