I was watching a C-span debate between Justice Scalia and Breyer about various aspects of the law. Breyer made a very interesting, and scary, point about how judges ought to handle ambiguity and impreciseness in laws. To illustrate, he talked about a case where the intention of a law is circumvented by strict adherence to the law. The intention may be that wages are fair, but because of impreciseness in the language, wages are unfair even though the law is followed to a T. In Breyer's opinion, when ruling in these types of situations, judges ought to take into account the intention, fair wages, and base their decision off of that. In essence, amending the law to "fill in the gaps". This is dangerous.
Think about this: you want to follow the law; you adhere to the law; but if you fail to anticipate what someone intended instead of what the law states, you could be breaking the law. This is a perversion of justice. It is not the responsibility of an individual to behave as one thinks he ought to behave. He must live by the rules of the game, and those rules are written down for everyone to see. Rules which no one knows, which are intentional, are not rules that can or should be enforced.
Breyers is trying to use the wrong tool for his purpose. Law by it's very definition is imprecise, lacking. It cannot account for all possibilities. It is not a means for codifying intentions and desires. You cannot write a law that states society will be fair and judges ought not whimsically attempt the practice of engineering a fair society. They should interpret the law.
