Why is ratio decidendi important?

• A. It is the part of reasoning that is persuasive but not binding
• B. It is the binding legal principle that explains the court's decision and binds future cases
• C. It deals with procedural issues
• D. It only applies to one case

Answer: (B)

Ratio decidendi is the binding legal principle that explains the court’s decision and binds future cases. It’s the rule of law distilled from the judgment—the core legal reasoning that actually decides the issue and can be applied to later cases with similar facts. This creates precedent under the doctrine of stare decisis, giving courts and lawyers a predictable, consistent framework for resolving disputes. Obiter dicta, in contrast, are remarks not essential to the decision and are persuasive but not binding.
