Law I / The Principle of Legality
Practice question · Sort into groups

Sort each defect by the requirement of the criminal statute that it violates.

Groups: Lex praevia · Lex stricta · Lex certa

Hints
  1. One column is about time, one about extension, one about precision.
  2. Two of the six are the judge's fault rather than the legislator's.
Show the answer

Lex praevia: Past acts punished, Past penalty raised

Lex stricta: Analogy to a horse, Analogy by purpose

Lex certa: Vague social order, Vague good practice

Why

The middle column contains judicial defects and the outer two contain legislative ones, which is worth noticing. Lex praevia and lex certa are addressed to the legislator, and a court can do nothing to repair a vague statute except decline to apply it; lex stricta is addressed to the court, and no amount of legislative care prevents a judge from stretching a good provision.
