Legal principles are fundamental rules and concepts that guide the interpretation and application of laws. They serve as the foundation for legal systems, helping to ensure fairness, justice, and consistency in legal proceedings. Examples of legal principles include due process, equal protection under the law, and the presumption of innocence. These principles are often derived from various sources, including statutes, case law, and constitutional provisions. They help judges and legal professionals make decisions and resolve disputes by providing a framework for understanding rights and responsibilities within a society.
