Bills passed by the Congress are reviewed by the supreme court. This statement best describes the characteristic feature of democracy.
Step-by-step explanation:
United states constitution highlights the greatest dictum of democracy and that is people sovereignty. It also says that no faction or any segment of the government must influence each other while exercising their powers. Unique aspect of Us constitution is that it frames a supervisory and regulatory authority which would hold one branch of the government to keep a watchful eye on the functions and operations of the other branch. This is called a system of checks and balances.
US constitution allows one branch of the government to exercise equal powers and regulate the operations of the other branches too. This is to ensure that no branch of the government exerts any kind of influence which paves way for any tyrannical move and this is against the system of democracy laid down in the constitution.
