Hard Cases Make Bad Law
Updated 2026-08-03
INTRODUCTION
English translation pending.
CORE DEFINITION
The maxim hard cases make bad law states that when a court resolves an extreme, emotionally charged, or highly unusual dispute, the ruling is often stretched into a broad precedent that then governs ordinary and quite different cases badly. The mechanism is that the pressure to do justice in the hard case forces a rule wider than the facts warrant. The principle generalizes to rule-making of any kind: policy should be designed for the typical case, with extreme cases handled by special procedures, rather than letting the exception write the rule.
SCAFFOLDING EFFECT
Reduce cognitive load
- Case typicality check: Ask whether the case driving the rule is typical or an extreme outlier. - Exception quarantine: Route extreme cases through special procedures instead of letting them rewrite general rules. - Scope discipline: Write the rule for the median situation and verify it does not distort normal behavior.
Anchor fast decisions
Rules are general, but hard cases are specific, and resolving a specific extreme requires either a narrow carve-out or a broad new principle. Pressure for a visible outcome pushes toward the broad principle, which then binds many ordinary cases the court never imagined. Over time the precedent, written for a freak fact pattern, governs routine disputes, and the law becomes a distortion of the typical case it was meant to serve.
