Natural justice in disciplinary proceedings bars witness-adjudicators and undisclosed adverse past conduct from supporting punishment.

Disciplinary action is vitiated where the Commandant who initiated the proceedings and appeared as a witness also participated in the inquiry and punishment, because such involvement creates a reasonable apprehension of bias and offends natural justice. The defect is not cured by later appellate affirmation, and the punishment is null and void. Past service record or adverse conduct cannot be relied on to justify or enhance punishment unless the delinquent is first informed and given an opportunity to respond. As the adverse material was not disclosed before punishment, the dismissal could not stand and consequential relief followed.

Issues: (i) Whether the disciplinary proceedings and punishment were vitiated because the Commandant, who initiated the proceedings and appeared as a witness, also acted in the matter of inquiry and punishment; (ii) Whether the appellant's past conduct could be relied upon to justify the punishment without prior notice to him.

Issue (i): Whether the disciplinary proceedings and punishment were vitiated because the Commandant, who initiated the proceedings and appeared as a witness, also acted in the matter of inquiry and punishment.

Analysis: A disciplinary proceeding must conform to the principles of natural justice. A person who has a personal stake in the dispute, or who has appeared as a witness in support of the charge, cannot act as the adjudicator in the same matter. The rule against bias applies with full force to quasi-judicial disciplinary action. Where the initiating authority is also a witness and then accepts the inquiry report and imposes punishment, the proceeding is tainted by a reasonable apprehension of bias and the defect is not cured by appellate affirmation.

Conclusion: The disciplinary proceedings and the punishment order were vitiated and were null and void.

Issue (ii): Whether the appellant's past conduct could be relied upon to justify the punishment without prior notice to him.

Analysis: If past service record is to be used for enhancing or justifying punishment, fairness requires that the delinquent be informed of that reliance and given an opportunity to respond. A punishment cannot be sustained on the basis of material not made part of the charge or disclosed in the show-cause process. In the present case, the adverse past conduct was not put to the appellant before the punishment was imposed.

Conclusion: The past conduct could not lawfully be used to sustain the punishment without prior notice.

Final Conclusion: The dismissal from service could not stand because the proceedings were conducted in violation of natural justice and the punishment was unsupported by a lawful procedure; the appellant was entitled to the consequential relief granted by the Court.

Ratio Decidendi: A disciplinary authority who is a witness in the same proceeding cannot adjudicate or punish in that matter, and punishment based on undisclosed adverse past conduct violates natural justice.
