I'd like to see it as : Ten pages. Plain English. Expected outcome (measured by third party) in a certain length of time. If that doesn't happen then a plan to get rid of the new law.
All laws should have automatic termination if not renewed. If it isn't important enough for Congress to keep voting for it, then it's not important enough to keep it as law.
Not to mention that such a restriction would put a limit on the number of laws. Eventually they would be forced to choose either to affirm old laws or pass new ones. There would not be enough time for them to do both.
