What is law supermacy

Supremacy of the law is a basic model in the western democratic order. This rule requires citizens and governments to be matter to known and standing law. ... The idea of the supremacy of law requires a definition of law (to which the above principles may prerogative decree.

The Supremacy Clause is a clause within Article VI of the U.S. Constitution which dictates that federal law is the "supreme law of the land."

The United States is a presidential representative democracy. We are presidential because our federal government is led by a president (who is essentially elected by the citizens) and not by a prime minister (who is elected by other elected officials). We are representative and democratic because we elect officials to represent us in government.

China is a one-party communist government that does not have fair or open elections, and is led by the leader of the Communist Party, who is chosen by other elite members of that party. Clearly, China is not the best answer.

South Africa is both parliamentary (it has a prime minister) and unitary (it is not a federal state). The U.S. is a federal state, which means it's a union of smaller state governments. So South Africa isn't a perfect match.

India and France have very similar government systems. They both have presidents and bicameral legislatures, are both democratic republics, and both have independent executive, legislative, and judicial branches that are designed to keep each other's power in check.

The key difference is that France is a unitary government, in which most government power is vested in the national government. India is a federal government, in which power is shared by a central government and by various states. For this reason, India is the closest to America, since America has a federal rather than unitary government.
