Courts are the backbone of justice systems worldwide. They're organized in levels, from local trial courts to supreme courts, each with specific roles and jurisdictions. Understanding this structure is key to grasping how legal cases move through the system.

Different court levels handle various case types and legal issues. Trial courts deal with initial hearings and evidence, while appellate courts review decisions. Supreme courts make final rulings on major legal questions, shaping the law for years to come.
