Surely the way that parliament says the court is wrong is to re-legislate. They can't just have a vote and say "that interpretation is wrong" if, for example, the Supreme Court rejects their interpretation.
I don't know the exact process but I don't see why they couldn't do that. Parliamentary supremacy means that Parliament is supreme. What they say, goes. It's a dictatorship of elected MPs, hopefully kept in check by the need to be elected.
