Navy Act Sections 131–137: Accused as Witness, Judicial Notice, Service Documents, Summons, Commissions & Material Witnesses

Sections 131 to 137 of the Navy Act, 1957 create a specialised evidentiary code within naval court-martial procedure. They protect the accused from being compelled to testify, permit limited judicial notice of service knowledge, create special presumptions for naval and official records, regulate compulsory attendance of witnesses and production of documents, provide for evidence by commission, and empower the Trial Judge Advocate to call or recall witnesses essential to a just decision.

Sections 131 to 137 of the Navy Act, 1957 should be read with Section 130, which applies the general law of evidence subject to the special provisions of the Navy Act. These sections are important because they identify areas where naval law deliberately modifies or supplements ordinary evidentiary procedure.

The official statutory text is available through India Code — Navy Act, 1957. The post-1 July 2024 evidence-law transition is explained separately in Navy Act Sections 128–130: Court-Martial Record & Evidence Law.

This article should also be read with Navy Act Sections 105–113: Trial Procedure, No-Case Submission & Defence Evidence, the guide to Navy Act Section 99 and the Trial Judge Advocate, and the broader Indian Navy Law pillar guide.

1. Section 131: the accused is a competent defence witness

Section 131 provides that a person accused of an offence before a court martial is a competent witness for the defence and may give evidence on oath in disproof of the charges made against him or against another person jointly charged at the same trial.

This means the accused is not legally disqualified from entering the witness box merely because he is the person on trial.

2. The accused cannot be compelled to become a witness

The protection is express. Section 131(a) states that the accused shall not be called as a witness except on his own request in writing.

The decision to testify therefore belongs to the accused. The prosecution, the TJA and the court members cannot compel him to give sworn defence evidence.

3. Written request is part of the statutory safeguard

The requirement of a written request is not an empty formality. It creates an objective record that the accused elected to testify voluntarily.

The trial record should therefore contain or clearly refer to the written request where the accused enters the witness box under Section 131.

4. Section 111(6) and Section 131 operate together

Section 111(6) requires the TJA, after rejection of a no-case plea and before the defence proceeds, to inform the accused that he may give evidence as a witness on his own behalf if he wishes and makes a written request, but that doing so renders him liable to cross-examination.

Section 131 supplies the underlying competence and voluntariness rule. Section 111 supplies the procedural warning at trial.

5. Sworn evidence is different from a statement from the accused

Naval procedure recognises an important distinction between:

• the accused giving evidence on oath under Section 131, after a written request and subject to cross-examination; and
• the accused making a statement as to the facts under Section 111(7), where he does not elect to give sworn evidence.

The two should not be treated as procedurally or evidentially identical.

6. No adverse comment from silence

Section 131(b) provides an unusually explicit safeguard. If the accused does not give evidence, that failure:

• shall not be made the subject of comment by any party;
• shall not be made the subject of comment by the court; and
• shall not give rise to any presumption against the accused or any jointly tried co-accused.

7. What would an unlawful adverse comment look like?

Potentially improper comments include suggestions that:

• an innocent person would have entered the witness box;
• silence confirms the prosecution version;
• failure to testify fills a gap in proof;
• an adverse inference should be drawn because the accused did not deny an allegation on oath; or
• a co-accused should be prejudiced because another accused declined to testify.

Such reasoning is difficult to reconcile with the express language of Section 131(b).

8. Cross-examination follows if the accused elects to testify

Once the accused voluntarily gives sworn evidence, he becomes a witness and is liable to cross-examination in accordance with the applicable evidentiary rules.

The protection is therefore a right not to be compelled to testify, not a right to give sworn evidence immune from testing.

9. Section 132: judicial notice of service knowledge

Section 132 permits a court martial to take judicial notice of any matter within the general naval, army or air force experience and knowledge of the members.

The provision recognises that military members may possess institutional knowledge about matters of service practice that an ordinary civilian court may require formal proof to establish.

10. Judicial notice is not a substitute for proving the offence

Section 132 should not be read as authority to create a legal prohibition, essential ingredient or binding order that the prosecution has failed to establish.

The distinction is between taking notice of matters of general service experience and using members’ personal or institutional assumptions to supply an unproved element of criminal liability.

11. Commander Ranvir Kumar Sinha: limits of service knowledge

In Commander Ranvir Kumar Sinha v. Union of India, the Bombay High Court considered an argument that experienced naval officers could take judicial notice under Section 132 of a supposed practice prohibiting sale of liquor to sailors on board ship.

The Court rejected the attempt to sustain the conviction merely through such service understanding where the underlying prohibition had not been clearly established in the operative legal material. The judgment is useful for the proposition that judicial notice cannot be used to manufacture an offence that has not been made out in clear legal terms.

The judgment is available at Indian Kanoon — Commander Ranvir Kumar Sinha v. Union of India.

12. General experience is not the same as private knowledge

A member’s private knowledge of disputed facts in the particular case is different from general naval or military experience.

If a member has personal knowledge of a material disputed event, document or witness, the issue may engage impartiality, disclosure and even witness-competency questions rather than Section 132 judicial notice.

13. Section 133: special presumptions for naval and official documents

Section 133 creates several specialised evidentiary shortcuts. These provisions reduce the need to call formal witnesses merely to prove official records, rank, service status, surrender or apprehension certificates, specified forensic reports and certain medical statements.

But each shortcut has its own statutory conditions. A document does not become admissible merely because it originated somewhere within the Navy.

14. Section 133(1): certified copies of service records

Section 133(1) applies to documents such as vouchers, receipts, accounts, musters, ship’s books, letters, signals, telegrams and other documents made or kept under legislation, Navy regulations or service custom.

A copy may be received as evidence where it purports to be signed and certified as a correct copy by:

• the officer for the time being commanding the ship in which the document was made or kept; or
• a Secretary to the Central Government.

15. Certification authority matters

Section 133(1) is specific about who may provide the statutory certification. A defence audit should therefore check:

• who certified the copy;
• that person’s appointment at the relevant time;
• where the original record was actually made or kept; and
• whether the certificate purports to certify correctness of the copy.

16. M.P. Verma illustrates a Section 133 certification challenge

In Lt. Cdr. M.P. Verma v. Union of India, one of the defence objections recorded before the Delhi High Court concerned whether the person who had certified copies was authorised under Section 133. The case illustrates the practical importance of checking the statutory certifier rather than assuming that any organisational head may authenticate the record for Section 133 purposes.

The judgment is available at Delhi High Court — Lt. Cdr. M.P. Verma v. Union of India.

17. Section 133(2): Navy List, Gazette and official publications

A Navy List, Gazette or other official document purporting to be published under the authority of the Central Government or Chief of the Naval Staff is evidence of:

• the status of officers;
• their rank; and
• appointments held by them,

until the contrary is proved.

18. Section 133(3): books of a ship and subjection to naval law

Where it is shown that a person is borne on the books of a ship of the Indian Navy, that fact is evidence that the person is subject to naval law until the contrary is proved.

The statutory explanation gives “books of a ship” a wide meaning and includes an official book, document or list purporting to contain the names of persons appointed to the ship.

19. “Until the contrary is proved” means rebuttable

The presumptions in Section 133(2) and (3) are not expressed as conclusive. The accused may therefore place contrary material before the court where rank, appointment or subjection to naval law is genuinely disputed.

20. Sections 133(4) and (5): desertion and absence certificates

For charges of desertion, improperly leaving ship or absence without leave, Section 133 permits certificates concerning surrender or apprehension to be used as evidence.

The provision covers certificates from specified service personnel and, where the person was taken to a police station after arrest or surrender, a certificate from the officer-in-charge stating the fact, date and place.

These matters remain rebuttable where the section says the certificate is evidence unless the contrary is proved.

21. Section 133(6): specified expert reports

Section 133(6), as expanded by amendment, permits reports under the hand of specified scientific and forensic authorities to be used as evidence. The list includes, among others:

• Chemical Examiner or Assistant Chemical Examiner to Government;
• Chief Inspector of Explosives;
• Director of Finger Print Bureau;
• Director of the Haffkine Institute;
• Director, Deputy Director or Assistant Director of a Central or State Forensic Science Laboratory; and
• Serologist to the Government.

22. A report being admissible does not make its conclusion unchallengeable

Section 133(6) facilitates reception of specified expert reports. It does not automatically resolve every dispute about:

• identity of the sample;
• chain of custody;
• condition of the sample;
• method of collection;
• relationship between the sample and the accused;
• scope of the expert conclusion; or
• other evidence contradicting the report.

23. Section 133(7): medical officer’s statement and the right to require attendance

A statement of a naval, army or air force medical officer taken and attested by the commanding officer may be given in evidence.

But the proviso is important: the court shall summon and examine the medical officer if either the prosecutor or the accused requires it.

This creates a direct statutory route for testing the medical opinion where its subject matter is disputed.

24. Section 133(8): deposition recorded while offender has absconded

If an offender has absconded and there is no immediate prospect of arrest, the commanding officer or other prescribed person may record depositions on oath in the offender’s absence.

Such a deposition is not freely usable in every later circumstance. On the offender’s arrest, it may be used only if the deponent is dead, incapable of giving evidence, or cannot be procured without unreasonable delay, expense or inconvenience.

25. Section 134: compulsory attendance of witnesses and production of documents

Section 134 governs the formal summons process.

For a person required to give evidence or produce a document before a court martial, the summons must be in writing and under the hand of the Judge Advocate General of the Navy or the Trial Judge Advocate.

26. Section 134 also extends to pre-trial stages

Section 134(2) separately provides a statutory summons mechanism for a person required to give evidence before:

• a commanding officer;
• the officer preparing a Summary of Evidence; or
• a board of inquiry.

This is important because compulsory witness attendance is not confined to the assembled court martial.

27. Service witnesses and civilian witnesses are served differently

Section 134 distinguishes between witnesses subject to naval, army or air-force law and other witnesses.

For a civilian or other non-service witness, the summons may be served in the prescribed manner or sent to the Magistrate within whose jurisdiction the witness is present or resides. The Magistrate must give effect to the summons as if the witness were required before that Magistrate’s own court.

28. A document summons must describe the item with reasonable precision

Section 134(5) requires a summons seeking production of a particular document or thing to describe it with reasonable precision.

A vague demand for “all records whatsoever” may therefore raise a different issue from a summons identifying a specific signal, ship’s log, file, device, register, inspection record or correspondence set.

29. Civilian witnesses are entitled to prescribed reasonable expenses

Section 134(6) provides that a person not subject to naval law who is summoned under the section shall be allowed and paid such reasonable expenses as may be prescribed.

30. Section 134(7): State-affairs and official-communication privilege

The present India Code text of Section 134(7) still refers to Sections 123 and 124 of the Indian Evidence Act, 1872 and preserves those privilege rules while also excluding documents in the custody of postal or telegraph authorities from the ordinary operation of the section.

After 1 July 2024, the corresponding subjects are now addressed in Sections 129 and 130 of the Bharatiya Sakshya Adhiniyam, 2023: evidence concerning unpublished official records relating to affairs of State and confidential official communications.

Official BSA text is available through India Code — Bharatiya Sakshya Adhiniyam, 2023.

31. A summons power does not automatically override statutory privilege

The existence of a summons under Section 134 does not by itself eliminate valid claims of privilege concerning State affairs, official confidence or other legally protected material.

The correct analysis separates:

• the power to summon or require production;
• the legal obligation to produce;
• the existence of statutory privilege; and
• the relevance and admissibility of what is ultimately produced.

32. Section 135: when evidence may be taken on commission

Section 135 applies where, during a court-martial trial, the TJA considers a witness necessary for the ends of justice but personal attendance cannot be procured without unreasonable delay, expense or inconvenience.

The TJA may then dispense with attendance and apply to JAG(N) to issue a commission for examination of the witness.

33. The TJA applies; JAG(N) decides whether to issue the commission

The statutory functions are distinct:

• the TJA identifies the need and makes the application; and
• JAG(N), if he thinks fit, issues the commission to the legally appropriate Magistrate or authority.

The court-martial may be adjourned for a specified period reasonably sufficient for execution and return of the commission.

34. Section 135 still contains CrPC 1973 references

The current printed Navy Act text continues to refer in Section 135 to the Code of Criminal Procedure, 1973 when describing the powers of the Magistrate executing the commission.

The CrPC was repealed from 1 July 2024 by Section 531 of the Bharatiya Nagarik Suraksha Sanhita, 2023, subject to its savings clause. The current BNSS commission provisions are principally Sections 319–323.

Official BNSS text is available through India Code — Bharatiya Nagarik Suraksha Sanhita, 2023.

35. Do not falsely rewrite Section 135

As with the stale Evidence Act references elsewhere in the Navy Act, legal drafting should distinguish:

• the words that Section 135 currently prints;
• the repeal of the CrPC;
• the BNSS repeal-and-savings regime; and
• the modern corresponding commission procedure.

It is better to explain the transition than to quote the Navy Act as though its text has already been formally substituted.

36. Section 136: interrogatories by both sides

When a commission is issued, both prosecutor and accused may forward written interrogatories which the TJA considers relevant to the issue.

The Magistrate or authority executing the commission examines the witness on the permitted interrogatories.

37. Personal or counsel participation in the commission

Section 136(2) allows the prosecutor and accused to appear before the Magistrate or authority by counsel. Except where the accused is in custody, the accused may also appear in person.

The parties may examine, cross-examine and re-examine the witness as applicable.

38. Commission evidence is not secret evidence

After execution, the commission and deposition return through JAG(N) to the TJA.

Section 136 requires the commission, return and deposition to be open to inspection by both prosecutor and accused. Subject to all just exceptions, either side may read the material in evidence and it becomes part of the trial proceedings.

39. Commission deposition may survive dissolution of the original court

Section 136(6) expressly permits a properly taken deposition to be received at a later stage of the trial and, if the original court is dissolved, before another court convened to try the accused on the same charges.

This gives commission evidence continuity across re-convening, subject to the statutory conditions and admissibility objections.

40. Section 137: broad power to call or recall material witnesses

Section 137 authorises the TJA, at any stage of the trial, to:

• summon any person as a witness;
• examine a person in attendance even though not formally summoned;
• recall a witness already examined; and
• re-examine a witness already examined.

41. Section 137 contains both discretionary and mandatory language

The first part says the TJA may summon, examine, recall or re-examine.

The second part is stronger: the TJA shall summon and examine or recall and re-examine a person if that evidence appears to the court or to the TJA to be essential to the just decision of the case.

42. The “essential to the just decision” test is the key threshold

The Section 137 power is not designed simply to help one side repair every weakness in presentation. Its compulsory aspect is tied to the interests of justice and the essential nature of the evidence.

Relevant questions include:

• What material issue does the witness address?
• Is that issue genuinely unresolved?
• Is the evidence cumulative or uniquely important?
• Would refusal leave the court without material needed for a just decision?
• Would calling the witness create unfair surprise that requires an adjournment or disclosure?
• Will both parties have a fair opportunity to examine or challenge the witness?

43. Santosh Karwade: Section 137 is analogous to the general criminal-court material-witness power

In Santosh Karwade v. Union of India, the Kerala High Court described Section 137 as analogous to the material-witness power under criminal procedure and emphasised its purpose of enabling essential evidence to be placed before the court martial for a just decision.

The Court considered a situation in which a prosecutor might possess first-hand knowledge relevant to the case. It distinguished competency to testify from credibility and recognised that the fact of a person being prosecutor does not by itself answer whether his evidence is legally necessary or what weight should ultimately be assigned to it.

The judgment is available at Indian Kanoon — Santosh Karwade v. Union of India.

44. A prosecutor as witness is an exceptional fairness issue

Where a prosecutor is proposed as a witness, the defence should distinguish several questions:

• Is the prosecutor legally competent to testify?
• Is the evidence genuinely first-hand and material?
• Is the evidence essential to a just decision?
• Can another independent witness prove the same fact?
• Does continuing simultaneously as prosecutor create an avoidable fairness or role-conflict concern?
• What cross-examination and procedural safeguards are required?

45. Section 137 cannot be used to deny cross-examination

A witness called or recalled under Section 137 does not become immune from ordinary fairness requirements. The opposing party must have a meaningful opportunity to test material evidence through the applicable examination process.

46. Section 137 and late evidence

Because Section 137 applies “at any stage of the trial,” the power can operate even after the ordinary prosecution or defence sequence has progressed substantially.

But the later the intervention, the more important it becomes to consider:

• notice;
• disclosure of the subject matter;
• time needed to prepare;
• recall of related witnesses;
• additional documentary production; and
• whether an adjournment is necessary to prevent prejudice.

47. Section 137 and the TJA’s duty of neutrality

The TJA may actively ensure that essential evidence is before the court, but the Section 137 power should not be converted into partisan prosecution reconstruction.

A challenge may become stronger where the record shows repeated intervention only to fill prosecution gaps, selective refusal to call equally material defence evidence, or questioning that abandons the TJA’s neutral judicial role.

48. A practical Sections 131–137 evidence audit

Issue	Provision	Key audit question
Accused testimony	131	Was there a voluntary written request?
Accused silence	131(b)	Was any adverse comment or presumption drawn?
Judicial notice	132	Was general service knowledge used to replace proof of a legal ingredient?
Certified naval record	133(1)	Was the copy certified by an authorised statutory certifier?
Medical statement	133(7)	Was the doctor summoned when required by a party?
Witness summons	134	Was the summons validly issued, served and sufficiently precise?
Commission	135–136	Was attendance genuinely unreasonable and were both sides able to participate?
Material witness	137	Was the evidence essential to a just decision and was fairness preserved?

49. Documents needed for an appellate challenge

• accused’s written request to testify, if any;
• Section 111(6) warning and election record;
• prosecution and defence closing submissions;
• TJA summing up showing whether silence was commented upon;
• documents or facts judicially noticed under Section 132;
• copies and certification endorsements relied on under Section 133;
• medical statements and requests to summon the medical officer;
• forensic reports and chain-of-custody material;
• witness and document summonses under Section 134;
• proof of service of summons;
• applications for commissions under Section 135;
• JAG(N) commission orders;
• interrogatories, depositions and cross-examination on commission;
• Section 137 applications or TJA directions to call or recall witnesses;
• orders on adjournment or disclosure following late evidence;
• Section 160 review and Section 162 petition records.

50. Common legal mistakes

• Treating an accused’s silence as incriminating. Section 131 expressly prohibits adverse comment or presumption.
• Confusing sworn testimony with an unsworn factual statement.
• Using Section 132 judicial notice to supply an unproved offence or order.
• Assuming any official-looking copy automatically satisfies Section 133(1).
• Ignoring the right to require a medical officer’s attendance under Section 133(7).
• Using an absconder deposition under Section 133(8) without checking statutory unavailability conditions.
• Issuing a document summons without reasonable precision.
• Assuming summons power automatically defeats State or official privilege.
• Using a commission merely for administrative convenience rather than the statutory delay/expense/inconvenience test.
• Applying old CrPC references in Section 135 without checking BNSS repeal and savings.
• Treating Section 137 as a partisan power to repair one side’s case.

51. Sections 131–137 in Section 160 JAG(N) review

A post-trial review ground should identify the exact evidentiary defect and its consequence. Examples include:

• adverse inference from the accused’s decision not to testify;
• conviction based on judicially noticed material outside Section 132;
• admission of a statutory copy not certified in the manner required by Section 133;
• refusal to summon a medical officer despite a valid Section 133(7) requirement;
• denial of a material defence summons;
• commission evidence taken without a fair opportunity to cross-examine;
• failure to call a witness whose evidence was essential to a just decision; or
• Section 137 intervention causing demonstrable procedural prejudice.

See Navy Act Section 160: JAG(N) Judicial Review.

52. Sections 131–137 in an AFT court-martial appeal

Under Section 15 of the Armed Forces Tribunal Act, an evidentiary or witness-procedure error should be linked to the legality of the finding, material irregularity or miscarriage of justice rather than pleaded as a technical breach alone.

A useful appellate structure is:

1. identify the exact Navy Act provision;
2. identify the evidence, witness or document concerned;
3. state the TJA ruling or court action;
4. state the correct statutory test;
5. show the evidence that was wrongly admitted, excluded or left untested;
6. show how the error entered the no-case ruling, defence stage, summing up or finding; and
7. state the resulting prejudice or miscarriage.

53. Frequently asked questions

Can the accused be forced to testify at a Navy court martial?

No. Section 131 says the accused cannot be called as a witness except on his own written request.

Can the prosecution comment on the accused’s failure to testify?

No. Section 131 expressly prohibits such comment and prohibits any presumption against the accused or a jointly tried co-accused.

Can court-martial members use their naval experience?

Section 132 permits judicial notice of matters within their general naval, army or air-force experience and knowledge, but that power should not be used to create an unproved legal prohibition or essential ingredient of an offence.

Who can certify a naval record under Section 133(1)?

The statutory text refers to the officer for the time being commanding the ship in which the document was made or kept, or a Secretary to the Central Government.

Can a medical officer’s written statement be used without calling the doctor?

Yes in the circumstances described by Section 133(7), but the court must summon and examine the medical officer if the prosecutor or accused requires it.

Can civilian witnesses be compelled to attend a Navy court martial?

Yes. Section 134 provides a formal summons mechanism and enables assistance through the Magistrate having jurisdiction over the civilian witness.

Can a Navy court martial compel production of secret Government records?

A summons does not automatically override statutory privilege. Section 134(7) preserves State-affairs and official-communication protections, which after the 2024 evidence-law transition correspond to BSA Sections 129 and 130.

When can a witness be examined on commission?

Where the witness is necessary for the ends of justice but personal attendance cannot reasonably be procured without disproportionate delay, expense or inconvenience, subject to Sections 135–136.

Can the defence cross-examine a witness examined on commission?

Yes. Section 136 allows participation through counsel and examination, cross-examination and re-examination in accordance with the statutory procedure.

Can the TJA call a witness who neither side called?

Yes. Section 137 permits the TJA to summon or examine a person at any stage and requires such action where the evidence appears essential to a just decision.

Can a prosecutor also be a witness?

Competency and fairness are separate questions. Santosh Karwade recognises that exceptional circumstances may make a prosecutor’s first-hand evidence relevant, while the court must still consider necessity, credibility, role conflict and procedural fairness.

Conclusion

Sections 131–137 show that naval evidence law is neither a simple copy of ordinary criminal procedure nor an unrestricted command process. The accused retains an express statutory choice whether to testify and cannot be prejudiced for remaining silent. Judicial notice is confined to genuine service knowledge. Official records receive special evidentiary treatment only when the statutory conditions are met. Witness summons and commissions are structured powers, and Section 137 equips the TJA to ensure that evidence essential to a just decision is not excluded merely because neither side initially presented it.

For defence and appellate work, the decisive question is usually not whether the Navy Act gives the court or TJA a power, but whether that power was exercised within its statutory conditions and with procedural fairness to the accused.
