Maxim 10.7.1

An exception proves the rule concerning things not excepted.

Exceptio probat regulam de rebus non exceptis.

Source: 11 Co. 41; 3 Term 722; Bacon, Aph. 17; Weisman, 40b Difficulty 1/5 — Foundational

Explanation

The existence of an exception implies the existence of a general rule from which the exception departs; what is excepted proves that everything else is within the rule.

Where this applies

  • The fact that an exception exists proves there's a general rule for everything else.
  • If the law carves out a specific exception, everything not excepted is within the rule.
  • The exception proves the rule for all the things not excepted.
