I would prefer a sunsetting scheme along the lines of tenuring objects in generation scavenging garbage collection. In essence newly created laws would be up for review after a short period of time at which point they are either trashed or batched into a group with a longer time until next review. Long lived laws (ex. don't murder people) which have passed many reviews would be tenured into a pool of rare or only forced review.

Along with this approach I would want a new mechanism for batching several individual single topic bills for collective passing on a single vote. That as opposed to the current U.S. model of bundling wholly unrelated legislation into a single bill for voting on.
