Yes, I don't think that it would work if laws are retroactive... But then it's quite unfair if they are not. It is an interesting idea, but I think there'll be a lot of tweaking to be done to the process to get something effective. For example, how long should the expiration date be, 6 years is to short because of the political football problem, 20 years is long if the laws aren't retroactive. Also what to do with the existing laws? Stage out their expiration? How do we choose which one will expire first? or should there be an easy way to strike down old laws?
