Abstract
Legal systems are foundational structures that guide societal norms, relationships, and governance through codified and enforceable rules. A systematic review of scholarly literature identifies the fundamental components of legal systems: legal norms, institutions, actors, processes, and principles. The findings emphasize the interdependence of these elements and their impact on the rule of law and justice delivery. This work contributes to the understanding of legal system structures and highlights the importance of coherent design and implementation for societal stability and equity.
