It said the conjured-up-out-of-nothing right in Roe v. Wade was not a valid argument that the federal government (through the Constitution) explicitly protects abortion.

Even legal scholars on the left admitted before the decision Roe v. Wade was a decision on very shaky ground and liable to be overturned.

So it was overturned, and the decision was the state's, not the federal government under current laws.

Nothing stops Congress from passing a national law on abortion. If they do, then the Supreme Court will recognize it.
