How do the constitutionally prescribed procedures by which the u. s. constitution can be changed reflect the concepts of federalism and sovereignty

The concepts of federalism and separation of powers are distinct but related principles of political organization that are deeply imbedded in American governmental theory and experience. They are often confused. This confusion arises because both concepts involve separating or dividing governmental powers among distinct political organs in order to make government responsive to people's needs and to keep government from becoming tyrannical. They are key elements of our government under law, our "pravovoye gosudarstvo."
