Maxim 1.5.100

In law every definition is dangerous.

In jure omnis definitio periculosa est.

Source: Jackson Difficulty 1/5 — Foundational

Explanation

Legal definitions risk being either too broad or too narrow — a rigid definition may exclude what should be included or include what should be excluded.

Where this applies

  • A legal definition turns out to be too broad and covers things it should not.
  • A court struggles because a statutory definition is too narrow to cover the actual situation.
