Which of the following is not a principle under the “Hot Stove Rule” of Douglas Mc Gregor ?

Douglas McGregor's 'Hot Stove Rule' draws an analogy between touching a hot stove and administering organizational discipline, resting on four core principles: advance warning, immediacy, consistency, and impersonality/impartiality. While natural justice in formal disciplinary proceedings requires an opportunity to defend, that procedural step is not one of the four metaphorical attributes of the Hot Stove Rule.
