Retained EU Law (Revocation and Reform) Bill

The noble Lord’s speech is quite intriguing. I have a question for him, although I do not know whether he will be able to answer it here and now. Is he suggesting that, if a piece of law were to be revoked because it was not included on the dashboard and had not been discovered through the search process, and that piece of law is later identified by a citizen and relied on in order to take a case to a court, that court would then have to determine whether that piece of law was retained EU law? What effect would that have on the deliberations of that court at that point?
