 That can indeed be the case if, for example, the purposes of the law are best served if a court is authorised to depart from what the legislature decided. But it is also possible for the law’s purposes to be served by treating a law maker’s contribution to the content of the law as being just what the law maker communicated. Consider for simplicity the making of a particular legal norm. With a gesture of a hand, a police officer at the scene of an accident can wave to a driver to indicate that she can go ahead, or can direct the driver to stop. The law, by authorising the officer to direct traffic, makes the officer’s gesture count as the law’s decision as to whether the driver has permission to proceed or a duty to stop.
