The decision made by the Supreme Court was that abortion was not a constitutionally-protected right, I doubt they would hold that allowing abortion was somehow unconstitutional. If that's what they wanted they would have gone ahead and declared that in their recent ruling. Instead they explicitly stated this is a matter for the legislature to decide.

Ahhh gotcha. Subtle but important difference. I think that I agree then.

By codified I think most people refer to it being enshrined into the Constitution.
