The key difference between constitutional courts and special courts lies in their jurisdiction, purpose, and the types of cases they handle. Constitutional courts are established by the constitution of a country to interpret and apply the constitution. They have the power to declare laws unconstitutional and handle cases involving constitutional issues or federal laws. Their primary role is to ensure that laws and government actions comply with the constitution. Special courts, also known as legislative courts, are created by the legislature to address specific types of cases such as tax disputes, military justice, or patent issues. These courts handle limited, specialized jurisdictions and are often designed to reduce the workload of the constitutional courts. The judges in special courts may not have lifetime appointments, unlike those in constitutional courts who usually do. In summary, constitutional courts focus on constitutional interpretation and broad constitutional matters, while special courts deal with specific legal issues under limited jurisdiction and usually have judges with limited terms rather than lifetime tenure.
