Precedent and Analogy in Legal Reasoning
Updated 2026-09-10
INTRODUCTION
English translation pending.
CORE DEFINITION
Reasoning from precedent and reasoning by analogy are two central forms of legal reasoning in many systems, especially common law systems such as those of England and the United States. A precedent applies when a later case is the same as an earlier one, so the earlier decision carries over; analogy applies when the later case is similar, so the earlier decision is extended.
SCAFFOLDING EFFECT
Reduce cognitive load
- Search for comparable cases: decide whether differences between cases affect their normative significance and so whether a precedent carries over. - Test distinctions: ask whether treating cases differently has a relevant basis, preventing arbitrary discretion. - Apply to new cases: extend an existing rule to unregulated situations on the basis of relevant similarity.
Anchor fast decisions
The binding force of precedent comes from formal justice: like cases should be treated alike, or similar parties will be treated arbitrarily. Analogy extends that demand to cases that are not identical, relying on a judgment of relevant similarity: if two cases are alike in normatively significant respects and their differences do not affect that significance, they should be treated the same way.
