Cheryl, federal law would supercede state law only IF there was a conflict.
But it is a provision of Roe v. Wade, ie the Federal mandate includes the provision that states be allowed to dictate what their law is in regards to abortion subsequent to the first trimester. This means that in some states where such a law has been passed, the state is within its rights to prosecute if the abortion is carried out and deemed to be (for e.g.) not due to risk to the mother's health.
Roe v. Wade is a uniform right for any person and in any place only up to the first 12 weeks. The states vary widely in what happens after that, and that IS a right given to states by Federal law.
I think there is a misunderstanding between us. You're getting into the nitty gritty of the law and talking about partial birth abortions.
You stated that abortion is illegal in the US in an earlier post and elaborated on your statement using Federal vs State law. However, abortion is legal in the US as per Roe v Wade. Federal law supercedes State laws in this matter. And, as you just pointed out, the Federal law leaves room for the States to determine the law for partial birth abortions and for other matters such as parental notification. Should those within a state disagree with laws such as parental notification, the matter can be brought before the Supreme Court which has the right to strike down the law if they deem it a violation of the Federal law.
In a nutshell: Abortions need to be done during the first trimester. It is illegal to perform a partial birth abortion unless the mother's life is at risk. If a woman has a partial birth abortion with no medical reason, she has committed a crime.
I just reread your posts and now see your train of thought. My original thoughts on your posts didn't follow along that path. Misunderstanding
I think your original statement threw me off as it seems to have done to others.
