I'd like to add that an ideal legal language should end up heavy with definitions. Whether or not a person has performed an action is often an important legal question, even after the a t is clearly defined and the person identified. To this end I think such a language should have some formal definitions of what it literally means for a specified person to perform a specified act.

You could go on for some time defining terms here, and would have to if you want to mechanically determine legal outcomes, once the required quantifiable facts have been established. I think you'd end up with something look like one of the ill-fated expert systems of yesteryear.
