Subsidiary Rules and Construction by Subject Matter

Unit 2 of Interpretation of Statutes (syllabus: Noscitur a sociis, ejusdem generis and reddendo singula singulis; restrictive and beneficial construction; taxing, penal and welfare statutes; mandatory and directory provisions; substantive and procedural law). Below: what the unit covers, the provisions it turns on, and the cases an examiner expects you to name.

What this unit covers

  • What is noscitur a sociis, and how does it differ from ejusdem generis?
  • When does the rule of ejusdem generis apply, and what are its conditions?
  • What does reddendo singula singulis do, and how does it differ from the rule of the last antecedent?
  • What is the difference between a substantive and an adjective statute, and why does it decide whether a new Act reaches pending matters?
  • What does it mean to say that a penal statute is construed strictly?
  • How is a taxing statute construed, and is it construed differently from any other statute?
  • What is beneficial construction, and how does it pair with restrictive construction?
  • How does a court decide whether a provision is mandatory or directory?

Treat that list as a self-test: recite each topic's rule from memory before you open its cases.
