A constitution is a framework document within a federal system that outlines political arrangements, such as the rights of all citizens, anti-discrimination and other policies, and the division of power between federal and constituent governments. Federal constitutions often leave space for constituent units to prescribe their own constitutional processes, but they include parameters that the constituent units must follow when drafting their constitutions.
Constitutions are the foundation of any federal system. They provide the framework for resolving disputes, safeguarding rights, and providing reform. These arrangements allow federations to effectively respond to challenges facing their countries. In other words, constitutions act as the guideline to the governance of federal systems.
