Laws are "reviewed" by courts, and in the UK newer laws automatically supersede older laws if there are any contradictions (with minor nuances as per Thoburn v Sunderland City Council). There's no need for the mechanism that you seem to have in mind (never mind that it doesn't work like that), we can and do change laws.

Laws aren't reviewed by courts at all. They're at best interpreted.
