Law I / The Anatomy of a Legal Norm
Practice question · Multiple choice

Why can a norm be valid and almost wholly ineffective at the same time?

Hints
  1. Ask what each property is a claim about.
  2. One is settled by tracing the norm's pedigree; the other by observing what people do.
Show the answer

B. Validity is membership of the system, settled by how the norm entered it; efficacy is a fact about behaviour

Why

Because they are claims about different things. Validity asks how the norm entered the system — competent organ, correct procedure, no conflict with a higher norm — and is settled by tracing its pedigree. Efficacy asks what people do, and is settled by observation. A competently enacted rule that everyone ignores scores full marks on the first and near zero on the second.
