The Court of Cassation is the highest court in many legal systems, primarily responsible for ensuring the uniform interpretation and application of law. It does not conduct trials or hear evidence; instead, it reviews decisions made by lower courts to determine if legal principles were correctly applied. This court plays a crucial role in maintaining the integrity of the judicial system by addressing issues of law rather than fact. Its rulings can set important legal precedents, influencing future cases and guiding lower courts in their decisions.
