Suppose the Supreme Court of the United States rules on an issue of a federal law and decides that a certain law is unconstitutional and cannot be enforced.
Then suppose Congress proposes an amendment to the states to amend the constitution to remove the language that made the law unconstitutional. This amendment is then ratified and becomes part of the constitution.
Does this in turn make the original law enforceable again? Or does Congress have to pass the law again in order for it to be enforceable?
Essentially my question is if the doctrine of stare decisis (or similar doctrine) prevents the enforcement of the old law until a new law is passed after adoption of the constitutional amendment.
Additionally, as there may be limited federal examples, I would be interested in similar situations which occur during interpretations of state constitutions.
