Why writers of constitution define powers of national?

Writers of constitutions define the powers of national government to establish a clear framework for governance, ensuring that authority is organized and distributed effectively. This delineation helps prevent the abuse of power by setting limits and responsibilities, promoting accountability and transparency. Additionally, it fosters a balance between national and state powers, which is essential for maintaining order and protecting citizens' rights. Ultimately, such definitions aim to create a stable political environment conducive to democracy and rule of law.
