Rules and the Rule of Law

FREDERICK SCHAUER*
What is the connection between rules and law? My goal here
is to address this question, and in doing so I will take up four
particular questions that the general one subsumes. First, must
law be an affair of rules? Does something about the nature of
law necessitate that legal decisionmaking involve the applica-
ion of preexisting rules? My second question is the mirror im-
age of the first. Can law be an affair of rules? Is rule-based
decisionmaking possible, and, if so, is it consistent with the idea
of law? Third, if law need not but can be based primarily on the
application of rules, then, descriptively, is it so? That is, are the
legal systems with which we are most familiar usefully ex-
plained by focusing on rules? Finally, if law need not but can be
based largely on rules, then, normatively, should it be? Ought
legal decisionmakers to be constrained by rules, and, if so,
when, and why?
Many contemporary debates in legal theory address one or
more of these interrelated questions. The disputes about legal
positivism as an account of law concern the place of a limited
set of rules in legal decisionmaking. Traditional and modern
versions of legal realism attack the view that legal decisionmak-
ing involves the simple application of preexisting rules. Other
theorists make the call to context, urging legal decisionmakers to
consider more features of any event than is possible through
the application of necessarily acontextual rules. Similarly, some
see law as essentially rhetorical, focusing on the different argu-
ments that prevail in cases rather than on the possibility that
fixed rules predetermine the resolution of those cases. Most re-
cently, American pragmatism' and Aristotelian practical rea-
son2 have inspired theorists to urge a decisionmaking mode
