CONSTITUTIONAL LAW — Legislative Competence — Residual Matters — Offence of Armed Robbery as State Offence

This principle establishes that armed robbery is a residual matter within the legislative competence of State Assemblies. It is not listed in the Exclusive or Concurrent Legislative Lists of the Constitution. Therefore, State Assemblies have the power to legislate on armed robbery. The principle applies in determining legislative competence. It ensures that the division of legislative powers is respected. The principle reflects the constitutional distribution of powers. It prevents the National Assembly from legislating on matters not allocated to it. The court must determine whether a matter is in the lists. The principle provides clarity on legislative jurisdiction.
