Does the judicial branch decide cases about the Constitution or the country's laws?

Answer 1

The Judicial Branch hears cases regarding laws of the nation, and weighs them with respect to the Constitution and unwritten precedents. So, in a way, both, but it is easiest to picture the Constitution as the ruler to which the courts measure laws to determine their constitutionality.

Answer 2

Once a bill is submitted to the President and the President signs the bill into law - it is the courts (judicial branch) that interpret the laws and makes decisions on how the law is applied.

However, due to the system of checks and balances existent in American government, a judge's decision can be challenged by either the President or Congress (or both) if there is any indication that the decision goes against the "Spirit of the Constitution".

Answer 3

That would be the Judicial branch.

This branch belongs to the US Supreme Court.

The supreme court inteprets the constitution and find out if any law in the constitution is violated.

Answer 4

Either branch of congress (Senate or House of Representatives) can submit a law for approval.

Both branches of congress have to approve a law for it to go into effect.

The President of the U.S. approves the law by signing it into effect or by default doing nothing.

The President can also veto it and prevent it from going into effect.

Congress can vote to override the veto with a two-third vote in both houses.

The U.S. Supreme Court can declare a vote unconstitutional and make it go away.

Then:

Congress or the states can start he process of introducing a constitutional amendment to get around the supreme court.
