Federal Law verses State Law?

If the state went by the state statue and you found a federal law and code of federal regulations states what they can and cannot do and the state did it wrong. You appeal the case. Will the state appeal board cut the Federal or not? Doesn't the Federal Law super see the state law?
yes it is called preemption, but only if the legislation or regulatory authority is delegate to the federal government by the Constitution.
That is governed by the 10th amendment, among other things. You are being far too indefinite. The answer is "it depends".

State courts are obligated to honor legitimate federal laws. If the federal law is a constitutional exercise of federal power, and is acceptable under the 10th amendment, then both state and federal courts are, as per the US constitution, obligated to uphold it rather than any state canon to the contrary.
