What happens if the president disagrees with a federal law?

Answer 1

No state can constitutionally have a law that conflicts with national laws. However, amendment can be made to the national constitution to make room for a difference so that a state may pass a law. An example can be the state law banning gay marriage. The Constitution bans the federal government from prohibiting freedom of religion, but it also states that the states reserve the right to govern certain aspects of the law at their own discression.

Answer 2

If the President disagrees with a federal law, he has the option of asking Congress to repeal the law, or in some cases, of asking the Supreme Court to rule on the constitutionality of the law. Since he presumably has some substantial reason for disagreeing with the law, he can explain his reason, and possibly get support for the idea of getting rid of that particular law.

Answer 3

The aggrieved individual(s) can file suit in federal court to bring the federal government into the case and the matter will be handled through the courts.

Answer 4

Federal law is over state, so the state law is invalid.

Answer 5

The federal law is over the state.
