Abstract
This article argues that legal precedents do not create rules, but rather create a special type of reason in favour of a decision in later cases. Precedents are often argued to be analogous to statutes in their law-creating function, but the common law practice of distinguishing is difficult to reconcile with orthodox accounts of the function of rules. Instead, a precedent amounts to a decision on the balance of reasons in the case before the precedent court, and later courts are required to decide cases on the basis that the earlier decision was correctly decided.
