I like your idea, but in practice it just won't work.

Any law requires interpretation and application.

[GSlob]

Application - yes, interpretation - not always. "The witches are to be burned" law [given as an example, for demonstration purposes only] does not leave much space for interpretation, or even for variations in application beyond using slow or fast fire. Indeed, the ideal constitution might even include a prohibition on any interpretation beyond literal meaning, thus precluding the development of a body of constitutional law.
