IN JUDICIAL DECISIONS
James J Eisenhower, III*
INTRODUCTION
When the lawyer, judge, or legal philosopher thinks of the doctrine of pre-
cedent, he or she begins with a conception close to that of Blackstone: It is an
established rule to abide by former precedents, where the same points come
again in litigation: as well as to keep the scale of justice even and steady, and not
liable to waiver with every new judge's opinion.' The idea of precedent is so
firmly established in our legal system it is iconlike. Though it has been described
as the everyday working rule of our law,12 we nevertheless remain divided on
its uses and limits. Conservatives and liberals argue that their approach to the
important legal issues of our time are rooted in precedent and history. Is the
doctrine so open to interpretation that it is now meaningless? This article offers
a critique of four separate theories of the role of precedent in judicial decisions, a
role which, though controversial, remains vital to the integrity of the American
legal system.
THE ROLE OF PRECEDENT
Precedent can be defined as a binding rule that has been stated and acted
upon by judges in individual decisions. The accumulation of these decisions, or
rather the bases of these decisions, form a body of common law that binds
later courts. The general rule, and distinctive quality, of precedent is that every
court is bound to follow any case decided by a court above it, and appellate
courts, other than the United States Supreme Court, are bound by their own
previous decisions.
The binding nature of precedent is derived from the general maxim that like
cases should be decided alike.3 This concept is based upon the idea that judicial
decisions, in order to be fair and predictable, must be consistent. The legal doc-
trine of adhering to precedent is termed stare decisis.4 Its application results in
court-made rules that resemble legislation by attempting to maintain a consis-
tent body of law that the public can look to and predict whether an individual
act will fall within its confines.
