I've always felt like laws should be reviewed every so often, maybe even re-passed, to be sure they are still relevant, make sense, and to see if they worked as intended.

There are at least some laws that don't make sense anymore or just flat out failed, but have big implications. Like blue laws, adultery laws, inheritance/intestacy laws, mandatory minimum sentences, sodomy laws, drug laws, etc..

But I do see problems in revisiting laws, it's expensive and time consuming. It would be a never ending battle for both sides, and we would get even less done.
