What does Common Law rely on for its principles?

Common Law is primarily based on the principles of precedent and customs. This legal system develops through judicial decisions made by courts, which create binding precedents for future cases. When judges make rulings, they refer to past case law, thus establishing a consistent interpretation of legal principles. This reliance on cumulative judicial decisions allows the legal system to adapt to changes in society over time while maintaining continuity.

In addition to precedents, customary practices within a specific jurisdiction also shape the Common Law. These customs reflect the accepted norms and practices that have evolved over time. Together, precedents and customs form the foundation of Common Law, distinguishing it from legal systems that primarily depend on written statutes or legislative measures. Thus, the essence of Common Law is rooted in these historical judicial decisions and social customs, making option C the correct choice.
