Abstract

In Law’s Empire, Ronald Dworkin introduces an important distinction between what he calls the ‘grounds’ and the ‘force’ of law. The former primarily interest Dworkin in LE and concern the “circumstances in which particular propositions of law should be taken to be sound or true.” (110) Propositions of law, we are told, are “all the various statements and claims people make about what the law allows or prohibits or entitles them to have.” (4) That Canadians owing income tax to the federal government must file their returns before April 30 or face a late penalty is presumably an example of a proposition of law. That the United States constitution prohibits slavery is another. These (true) propositions of law simply report the law’s (present) requirements, requirements which normally should be respected but which might justifiably be disobeyed or disregarded in exceptional cases. A true proposition of law, then, does not necessarily entail an answer to the question: What should I do, or decide (if called upon to render a judicial decision)? It also does not necessarily entail an answer to the question: Should the coercive power of the state be exercised against this person?
