Constitutional courts are specialized judicial bodies that focus on interpreting and upholding a country's constitution. Their primary role is to ensure that laws and government actions comply with constitutional principles. These courts often handle cases involving fundamental rights, the separation of powers, and the legality of legislation. In many countries, constitutional courts have the authority to review laws and can declare them unconstitutional if they violate constitutional provisions. This process helps protect individual rights and maintain the rule of law. Examples of such courts include the U.S. Supreme Court and the German Federal Constitutional Court.
