The Supreme Court has consistently held that civil, criminal, and departmental proceedings arising from the same facts can run simultaneously because they operate under different standards of proof and serve distinct purposes. A criminal acquittal does not bar a departmental inquiry or civil suit. However, courts may stay one proceeding to prevent prejudice. The standard in criminal courts is proof beyond reasonable doubt, while departmental inquiries use the preponderance of probability standard, making parallel proceedings legally permissible.

This doctrine rests on a foundational distinction: different proceedings serve different masters. A criminal prosecution protects society by punishing wrongdoing; a civil suit vindicates private rights; a departmental inquiry protects the integrity of a public service. Because each operates under its own evidentiary standard and adjudicatory purpose, the doctrine against double jeopardy under Article 20(2) of the Constitution — which bars second prosecution for the same offence — does not apply across these three tracks.

The Supreme Court crystallised this in State of Rajasthan v. B.K. Meena (1996) and reiterated it in Capt. M. Paul Anthony v. Bharat Gold Mines Ltd. (1999): an acquittal in a criminal court will not automatically vitiate a departmental proceeding unless (a) the charges are identical, (b) the witnesses and evidence are common, and (c) the departmental authority had an opportunity to lead evidence but failed. This three-condition exception is a frequent examiner target.

Courts retain discretion to stay one proceeding to prevent prejudice — for instance, staying a departmental inquiry while a criminal trial is ongoing to protect the accused's right against self-incrimination. This is not an automatic right but a discretionary judicial exercise.

For CLAT PG, the key conceptual architecture is: parallel proceedings are the rule, not the exception; acquittal in one forum is not a shield in another; and stays are discretionary, not mandatory.
