As far as regulations are concerned, in the United States, there's a legal principle called "Supremacy".This means that if there is a conflict between a local law and state law or federal law, the highest government rules.So, for example:Suppose a local law says "Black females can't be cops."The state law says "Females can be cops but blacks can't be."In this case, females (who are not black) can be cops in the local jurisdiction.However, if Federal law says "The right to be a cop shall not be denied to anyone on the basis or race or gender", then both at the state and local level, anyone who wants to be a cop cannot be prevented from being one solely on the basis or race or gender."So Federal Law > State Law > Local Law.That's Supremacy.Now, something that often happens is that states or local governments or even the Federal Government sue each other because they may believe that Supremacy may not apply to them.For instance, suppose a state has a law "No cop may wear jewelry other than a watch while on duty."Meanwhile, the Federal Government had a law "A cops must wear a nose ring on Tuesdays while on duty."Supremacy would force the cops in that state to wear a nose ring on Tuesdays.But, what would happen is that the state would sue the Federal Government in Federal Court saying that the law about cops wearing nose rings is unconstitutional because it is a violation of the 9th and/or 10th Amendments because this is a state's rights issue and that the Federal Government has no power to make such a law affecting the state. In this particular example case, supremacy would fail and the state would win so cops would not have to wear nose rings... or any other jewelry except a watch while on duty because the state law is supreme law in this case.Understand?It's just like military.
@abc3643 I understand Supremacy. That's why I asked the question, but I guess I didn't word it quite right to get across my full intent. Thanks, I'll post another more detailed poll.
