Kerala High Court Rules Investigating Officer Can Act as Prosecutor in Navy Court-Martial

In a pivotal judgment clarifying the contours of fair trial rights within the military justice system, the Kerala High Court has upheld the legality of a naval regulation that allows an investigating officer to also serve as the prosecutor in a court-martial. A Division Bench of Justice K. Natarajan and Justice Johnson John set aside a single judge's observation that such dual roles inherently violate Article 21 of the Constitution, ruling instead that the provision is valid under the restrictions permissible for the armed forces.

The Case: A Naval Officer's Challenge to Dual Roles

The dispute stemmed from a court-martial proceeding against Santosh Karwade , a naval officer with 31 years of service, who was accused of dishonestly inducing a fellow officer to transfer ₹1.10 lakh. During the trial, Karwade discovered that the officer who had investigated the allegations against him had been appointed as the prosecutor. He promptly approached the High Court, arguing that this arrangement breached his right to a free and fair trial under Article 21.

Karwade specifically challenged Regulation 178(3) of the Navy (Discipline and Miscellaneous Provisions) Regulations, 1965 , which states that "the prosecutor is a competent witness ." He contended that the regulation permitted an unconstitutional conflation of roles , as the investigating officer —who had already formed an opinion—could not be a suitable person to prosecute.

Arguments from Both Sides

The petitioner's counsel, Smt. Aysha Abraham , argued that the regulation violated basic principles of criminal jurisprudence and that the word "suitable person" in Regulation 163(1) could not include the investigating officer. She relied on precedents that emphasized the need for an independent prosecutor to ensure a fair trial.

The Union of India, represented by Additional Solicitor General Shri P. Sreekumar , countered that Article 33 of the Constitution empowers Parliament to restrict fundamental rights for armed forces personnel. He pointed out that the Navy Act and the Regulations form a complete code, and the Code of Criminal Procedure does not apply to court-martial proceedings. The ASGI also argued that the prosecutor's role is limited to placing evidence before the court, and that the single judge's observation was unwarranted.

Court's Legal Analysis: A Self-Contained Code

The Division Bench conducted a detailed analysis of the Navy Act, the Regulations, and the interplay with the Constitution. It noted that Section 4 of the Navy Act specifically restricts fundamental rights to the extent provided in the Act, and Section 5 of the CrPC saves special laws like the Navy Act from its application. The court observed that the Regulations in Chapter V provide a complete procedural code for investigations, trials, and sentences.

On the core issue, the court held that Regulation 178(3) does not explicitly prohibit the investigating officer from being appointed as prosecutor. Instead, it impliedly permits it, as the prosecutor can be called as a witness. The court rejected the argument that this arrangement violates Article 21, stating:

" Regulation 178(3) of the Navy Regulations cannot be said to be ultra vires to Article 21 of the Constitution of India, but it is valid in view of the restrictions under Article 33 of the Constitution of India."

The bench also clarified the role of the prosecutor, distinguishing it from that of a judge:

"The sole duty of the prosecutor is to place the evidence before the court-martial . The judgment or order of sentence is to be delivered by the court-martial itself, and not by the prosecutor . Therefore, the prosecutor need not be an independent authority but must be a suitable person for prosecuting the case before the court-martial ."

The court further distinguished the Supreme Court's ruling in V.K. Singh's case (2026), noting that it involved the Official Secrets Act, where no special law existed, and thus the CrPC applied.

The Decision and Its Implications

The Division Bench dismissed the appeal filed by Santosh Karwade and allowed the appeal filed by the Union of India. It set aside the single judge's observation that appointing the investigating officer as prosecutor would prejudice the trial. The court made it clear that the issue of whether the trial was vitiated due to the prosecutor's role would be left to the Armed Forces Tribunal to decide, should Karwade challenge his conviction and sentence.

This ruling affirms the special status of military law and the parliamentary power to restrict fundamental rights for discipline and efficiency in the armed forces. It also provides clarity for numerous pending court-martial cases where investigating officers have been appointed as prosecutors, effectively upholding the existing practice under the Navy Regulations.
