If a law is revoked, does your criminal

[PaulSabin]

....Record disappear? What if you have paid fines or fixed penalty notices for the revoked offence?

I think not. Likewise, when a new law is passed, they don't go out and round up people who did something illegal while it was still legal. You can only break laws that are in force at the time you do it.

Many laws are replaced and revoked, eg. the Gambling Act 2005 became law last weekend and the old Gaming Act 1968 passed into history. There are still people likely to appear in court in the future for breaching the old Act. They don't just give up prosecuting people who offended the old law just because a new law has come in. Therefore, actual convictions will also still be recorded and valid.
