Yes, and that's typically a violation since most abortions are legal. Therefore, any attempt to restrict that right can be and should be declared unconstitutional.
It isn't really important not, but even the defenders of
Roe v.Wade often admit it was a bad decision. In Planned Parenthood v. Casey, for example, the majority decided not to overturn
Roe v. Wade, but the majority opinion made it clear they felt it was bad jurisprudence. They simply suggested that it was precedent and that was that (although many of these judges would have had no compunction in overturning other precedent). Whether
Roe should hold is controversial and depends upon both what you think of the original ruling and what you think about overturning bad rulings.
As odd as this sounds, the Constitution is what the SCOTUS says its-- Marbury v Madison. Therefore, even though a particular decision may be reversed by later SCOTUS decisions, no decision is intrinsically "illegitimate".
In
Marbury, John Marshall explicitly derived the courts right of judicial review from the clear meaning and words of the constitution and the courts right to apply this as a legal entreprise. That seems quite the opposite to suggesting the constitution is simply what SCOTUS says it is. Their role comes from the fact that they only have to operate at the edges, extending and clarifying, rather than making the whole thing up. After all, if the constitution is so malleable as to be anything a judge can make it, why leave such power to judges? If the meaning of the constitution can be changed radically for political reasons, then surely a body of unelected judges is a strange organ to vest such power in. The legislature would seem a far better body. This was the traditional role of the Crown-in-parliament in Britain.
If the court is to rule on the constitution simply as it pleases, then they aren't really doing law any more and without the issue of constitutionality being a proper legal one, it seems even less necessary to vest the power to decide upon it in the Supreme Court.
I'm left-libertarian, and I entirely disagree with you. No party will likely fully reflect what most people may personally believe, but the Republican Party is much further away from my position than the Dems are. However, that's another discussion on another topic.
I didn't suggest the Republicans were a better party for a left-libertarian. They would be a better party for a right-libertarian. But neither Democrats nor Republicans are especially good for any sort of libertarian.
What specifically are you referring to here?
The decisions that have incorporated those parts of the Bill of Rights not explicitly incorporated by the Fourteenth Amendment, beginning in the 1920s.
