Navy Act Section 99: Trial Judge Advocate — Appointment, Powers, Legal Rulings, Independence & AFT Challenge

Section 99 of the Navy Act, 1957 makes the Trial Judge Advocate an indispensable legal officer in every naval court martial. The TJA administers the legal framework of the trial, decides questions of law, rules on relevancy and admissibility, controls improper questions, guides the court on law and safeguards the procedural integrity of the proceedings.

Section 99 of the Navy Act, 1957 requires every naval court martial to be attended by a Trial Judge Advocate (TJA). The TJA may be a judge advocate from the department of the Judge Advocate General of the Navy [JAG(N)] or, subject to the statutory and regulatory scheme, another fit person appointed by the convening officer.

The TJA is not simply an administrative assistant to the president of the court. Sections 101 to 121 of the Navy Act assign the TJA a series of judicial and procedural functions, and Section 114 makes the TJA the authority responsible for deciding all questions of law arising during the trial.

At the same time, the statutory division of functions is equally important. Under Section 115, it is the court martial—not the TJA—that decides which view of the facts is true and arrives at the finding. Under Section 116(2), the TJA must not sit with the court while it considers the finding. By contrast, under Section 120(2), the TJA sits with the court when sentence is considered, assists the court, but has no vote.

Official statutory materials are available through India Code — Navy Act, 1957 and the official Navy (Discipline and Miscellaneous Provisions) Regulations, 1965.

This article should be read with the Indian Navy Law pillar guide, the detailed article on Navy Act Section 97 and court-martial constitution, and the article on Navy Regulation 156 and convening validity.

1. What does Section 99 of the Navy Act provide?

Section 99(1) provides that every court martial shall be attended by a Trial Judge Advocate. The person appointed must be either:

• a judge advocate in the department of the Judge Advocate General of the Navy; or
• any fit person appointed by the convening officer in accordance with the statutory scheme.

For a court martial involving a capital offence, Section 99 contains an enhanced safeguard: the TJA must ordinarily be a person nominated by the JAG(N), unless the trial is held outside Indian waters.

Section 99(2) then expressly requires the TJA to administer the oath to every witness and to perform the other duties prescribed by the Act and Regulations.

2. Regulation 161: how is the Trial Judge Advocate appointed?

The appointment mechanism is elaborated in Regulation 161 of the Navy (Discipline and Miscellaneous Provisions) Regulations, 1965.

Where a judge advocate from the JAG(N) department is already on the staff of the convening authority, that judge advocate will ordinarily act as TJA. Where there are two or more such judge advocates, one is selected in consultation with the senior judge advocate.

Where no departmental judge advocate is available on the convening authority’s staff, the convening authority should ordinarily request that the services of a judge advocate be made available. If one is nominated, that person becomes the TJA for the proposed court martial.

Only where the services of a departmental judge advocate are unavailable may the convening authority appoint another fit person as TJA, subject to the special rule for capital-offence trials.

3. Is a separate warrant always required for appointment?

No. Regulation 161 distinguishes between departmental judge advocates and other persons.

• If the TJA is already a judge advocate in the department of the JAG(N), a special warrant to act is not necessary.
• If the TJA is not a departmental judge advocate, appointment must be made by warrant in the prescribed form.

A defence audit should therefore verify both the identity of the TJA and the legal basis on which that person was appointed.

4. What documents must the TJA receive before trial?

Under Regulation 162, the convening authority transmits to the TJA:

• a copy of the warrant issued to the president;
• the circumstantial letter;
• the charge-sheet and other documents required under Regulation 154; and
• sufficient copies to enable the relevant papers to be furnished to each accused.

This is important because the TJA cannot properly discharge the notice, document-supply and trial-control functions without the legally required pre-trial record.

5. Regulation 169: notice of trial is a TJA responsibility

Regulation 169 places important pre-trial duties directly on the TJA. The TJA must:

• give timely notice to the accused of the time and date of trial;
• cause the accused to receive the charge-sheet;
• cause the accused to receive the circumstantial letter;
• cause the accused to receive the Summary of Evidence;
• cause the accused to receive the prosecution exhibit list;
• inform the accused that defence witnesses whose attendance can reasonably be procured will be summoned; and
• inform the accused of the statutory position regarding giving evidence on his own behalf.

A challenge alleging denial of defence preparation should therefore examine not only the conduct of the prosecutor or Commanding Officer but also whether the TJA properly performed these notice and supply duties.

6. Regulation 171: TJA and attendance of witnesses

Regulation 171 requires the TJA to take necessary steps to procure the attendance of witnesses whom either the prosecutor or the accused desires to call and whose attendance can reasonably be procured.

This duty is important when the defence alleges:

• refusal to summon relevant defence witnesses;
• selective summoning of prosecution witnesses;
• failure to issue summons despite a proper request;
• unreasonable treatment of relevance; or
• denial of parity in witness procurement.

Section 134 of the Navy Act separately provides statutory authority for summoning witnesses before a court martial through the JAG(N) or TJA.

7. The TJA is not the prosecutor

The Navy Regulations separately provide for appointment of a prosecutor. The TJA and prosecutor therefore perform legally distinct functions.

The prosecutor presents the prosecution case. The TJA decides questions of law and ensures the trial proceeds according to statute and regulation.

This distinction becomes critical where the TJA has participated materially in preparing the prosecution case before trial. Such prior involvement may create an issue of independence or apparent bias, particularly if the TJA helped frame the charges, draft the circumstantial letter, advise the prosecution or otherwise became invested in the prosecution theory.

8. Section 101: TJA controls the commencement sequence

Section 101 assigns the TJA an active role at the moment the court martial assembles.

The TJA must read:

• the warrant for assembling the court;
• the names of officers exempted under Section 97(20);
• the reasons for those exemptions; and
• the names of the officers composing the court.

The TJA must then ask the prosecutor whether there is any objection to a member, and after prosecution objections are disposed of, ask the accused whether he objects to any member.

9. Section 102: what can the TJA decide about objections to members?

Section 102 draws a strict line.

If an objection is not made on a ground affecting a member’s competency to act as an impartial judge, the TJA may summarily reject it.

But where the objection is genuinely based on the member’s ability to act impartially, the TJA cannot decide the factual merits of that objection himself. The objection must be dealt with through the statutory procedure by the court.

10. Supreme Court: TJA cannot usurp the Section 102 function

In Union of India v. Shivendra Bikaram Singh, the Supreme Court examined a naval court martial in which objections to two members were summarily rejected by the TJA.

The Court held that once an objection is of the statutory type—namely, one affecting the competency of a member to act as an impartial judge—the TJA cannot decide whether the factual basis is persuasive and reject it on merits. The matter must be put through the decision mechanism prescribed by Section 102.

The Supreme Court treated the breach as serious enough to go to the root of jurisdiction and vitiate the proceedings.

11. Section 103: further constitution objections

After Section 102 objections have been disposed of, the TJA must ask the accused whether he has any further objection respecting the constitution of the court.

These broader constitution objections are decided by the court under Section 103.

The TJA’s duty at this stage is therefore procedural and legal: ensure that the statutory opportunity is actually given and that the objection is dealt with before oath and arraignment.

12. Section 104: oath of the members and TJA

The TJA administers the statutory oath or affirmation to the president and members. Thereafter, the president administers the oath or affirmation to the TJA.

The TJA’s oath is significant. It requires performance of the office according to law, without fear or favour, affection or ill-will, and reinforces the requirement of impartiality.

13. Section 105: arraignment and guilty plea safeguards

The TJA reads the charges and asks the accused whether he pleads guilty or not guilty.

If the accused pleads guilty, the TJA must ensure that the accused understands:

• the charge;
• the legal meaning of the plea; and
• the difference in procedure that follows from a guilty plea.

If the accused’s answers or the Summary of Evidence indicate that a guilty plea may be inappropriate, Section 105 permits the TJA to advise withdrawal of that plea.

A defective guilty-plea process can therefore become a significant appellate issue where the TJA failed to ensure an informed and legally sustainable plea.

14. Section 107: prosecution witness not in original list

Where the prosecution seeks to call a witness who was not included in the original list, the applicable statutory procedure must be followed. The TJA’s legal-control role becomes important in assessing notice, relevance, fairness and prejudice to the defence.

15. Sections 108 and 109: interpreter and record personnel

The Navy Act requires the interpreter and shorthand-writer or recording officer to be properly sworn or affirmed and permits objections to such persons in accordance with the statutory procedure.

The TJA administers or supervises these procedural safeguards and must ensure the integrity of the trial record and interpretation process.

16. Section 110: administration of oath to witnesses

Section 99(2) and Section 110 place the administration of the witness oath within the TJA’s responsibilities.

This is not ceremonial only. The legal status of testimony depends on compliance with the applicable oath or affirmation requirements, subject to statutory exceptions.

17. Section 111: plea of no case and defence stage

At the close of the prosecution case, questions may arise as to whether the evidence is legally capable of supporting the charge. This is a classic example of the division between law and fact.

The TJA determines the legal question: whether there is evidence upon which the charge can lawfully proceed. The court ultimately determines the facts and the finding.

Accordingly, a no-case objection should identify the missing legal ingredient and show why the prosecution evidence, taken at its highest where the applicable standard requires, does not establish a case fit to proceed.

18. Section 113: TJA’s summing up

After the defence case and any prosecution reply are concluded, Section 113 requires the TJA to sum up the evidence in open court and lay down the law by which the court is to be guided.

The summing up is one of the most consequential parts of a naval court martial because the members are not necessarily legally trained. The TJA must therefore accurately explain:

• the elements of each charge;
• the burden and standard of proof;
• relevant statutory definitions;
• legal defences properly arising;
• rules governing admissibility and use of particular evidence;
• the distinction between direct and circumstantial evidence where relevant;
• the legal effect of admissions, confessions or documentary evidence; and
• the separate responsibility of the members to decide factual credibility and guilt.

19. Can an erroneous summing up invalidate the finding?

Potentially, yes. If the TJA materially misdirects the court on the ingredients of the offence, burden of proof, evidentiary use or a defence available in law, the error may affect the legality of the finding.

The strength of the challenge depends on:

• the exact direction given;
• the correct legal position;
• whether the error related to a material issue;
• whether the error was corrected;
• whether the defence objected; and
• whether the misdirection caused or could have caused miscarriage of justice.

20. Section 114: TJA decides all questions of law

Section 114(1) is the central provision defining the TJA’s judicial role. It makes it the duty of the TJA to decide all questions of law arising during the trial.

The section specifically includes:

• relevancy of facts proposed to be proved;
• admissibility of evidence;
• propriety of questions asked by either side; and
• the discretionary power to prevent inadmissible evidence even where neither party objects.

This last power is important. The TJA is not required to remain passive merely because defence counsel fails to object. The statute places an independent responsibility on the TJA to prevent legally inadmissible material from contaminating the trial.

21. Can the TJA hear legal arguments outside the presence of members?

Yes. Section 114(2) permits the TJA, where desirable, to advise the president that arguments concerning admissibility, separate trials or other points of law should not be heard in the presence of the court members.

The president must then arrange for the court to retire or permit the legal argument to be heard in another convenient place.

This protects the members from hearing potentially prejudicial material before the TJA has decided whether that material is legally admissible.

22. TJA and inadmissible confessions or statements

The official procedural forms themselves illustrate the TJA’s role in dealing with an objection to a confession. The legal question of voluntariness and admissibility is dealt with before the evidence is allowed to reach the members.

Where a confession, admission or statement is challenged, the TJA should identify the legal rule governing admissibility and decide the question on the evidence relevant to that issue before the court uses the statement.

23. TJA may ask questions—but must remain neutral

The statutory forms and court-martial practice permit examination by the TJA where necessary to clarify evidence or resolve a legal issue.

However, questioning by the TJA should not become prosecution advocacy. Relevant indicators of improper intervention may include:

• repeatedly rehabilitating prosecution witnesses after cross-examination;
• introducing a prosecution theory not advanced by the prosecutor;
• cross-examining the accused in an adversarial manner;
• suggesting answers to witnesses;
• using questioning to fill fundamental gaps in the prosecution case; or
• displaying hostility or predetermined conclusions.

The question is not whether the TJA asked questions, but whether the manner and purpose of intervention remained consistent with neutral judicial assistance.

24. Section 115: TJA is not the fact-finder

Section 115 makes the division of responsibility explicit: the court decides which view of the facts is true and arrives at the finding.

The TJA may explain the law and rule on the legal use of evidence, but cannot direct the members that a disputed witness must be believed or that a contested fact has been proved.

A summing up crosses the statutory line if it effectively substitutes the TJA’s factual conclusions for the independent judgment of the members.

25. Section 116: TJA must withdraw when guilt is deliberated

After the TJA completes the summing up, the court is cleared to consider its finding.

Section 116(2) expressly provides that the TJA shall not sit with the court while the court is considering the finding. No person may communicate with the court during that deliberation.

This safeguard is fundamental to the independence of the members’ verdict.

If the record suggests that the TJA remained with the members, communicated with them privately about guilt or participated in their factual deliberation, the issue should be examined as a serious statutory irregularity.

26. Sections 117 and 118: finding and formal record

Once the members have decided the finding, the president communicates it to the TJA in open court. The TJA then draws up the finding as announced.

The finding is signed by the members by way of attestation and countersigned by the TJA.

The TJA does not create the verdict; the TJA formally records the verdict reached by the court.

27. Section 119: previous character and convictions

After a finding of guilt, the court may receive evidence concerning character and previous convictions in accordance with Section 119.

The TJA has a role in reading and handling the prescribed service documents and ensuring that impermissible prejudicial material does not infect the guilt stage before conviction.

This timing matters. Previous convictions and adverse character material should not ordinarily influence the members’ decision on whether the accused committed the charged offence.

28. Section 120: TJA sits during sentence deliberations but cannot vote

The statutory position changes once guilt has been determined.

Under Section 120(2), the TJA sits with the court while it considers sentence and assists in determining the proper punishment. But the TJA has no vote on sentence.

This means the TJA may advise on:

• the punishments legally available;
• maximum or minimum statutory limits;
• consequential punishments;
• legality of combination of punishments;
• relevant mitigating or aggravating considerations; and
• the proper statutory form of sentence.

29. Section 121: drawing up and pronouncing sentence

After the court decides the sentence, the TJA draws it up in the prescribed form. The members sign it and the TJA countersigns it.

The TJA then pronounces the sentence by direction of the court.

Again, the distinction is important: the sentence belongs to the court; the TJA ensures that it is legally and formally expressed.

30. Regulation 175: shared responsibility for lawful conduct of the trial

Regulation 175 provides that the president and TJA are together responsible for ensuring that the trial is conducted in accordance with the Navy Act and Regulations.

This reinforces the TJA’s institutional function as a safeguard of legality rather than an adjunct of the prosecution.

31. Can the TJA be challenged for bias?

Yes. The TJA exercises judicial functions of substantial importance and must be impartial.

The Delhi High Court in Avtar Singh v. Union of India stressed the need for an independent, unbiased and fair TJA. The Court examined a case where the same officer had been involved before trial in drafting the charge-sheet, framing the circumstantial letter and advising the authorities and prosecution, and was then appointed TJA.

The Court treated that degree of prior involvement as creating a serious issue of objectivity and impartiality.

32. What kind of prior involvement creates a bias concern?

Not every earlier administrative contact automatically disqualifies a TJA. The inquiry is fact-specific.

Relevant circumstances may include whether the proposed TJA:

• helped frame the charges;
• drafted or materially settled the circumstantial letter;
• advised the Convening Authority on the merits of prosecution;
• advised the prosecutor on how to present the case;
• expressed a concluded view that the accused was guilty;
• was materially involved in filling evidentiary gaps before trial;
• participated in an investigation into the same allegations; or
• has some personal or institutional interest in sustaining the prosecution case.

The legal issue is whether the circumstances create a real and reasonable apprehension that the officer may not act impartially in the judicial role assigned by the Navy Act.

33. Avtar Singh: why TJA independence matters

In Avtar Singh, the Delhi High Court emphasised that the TJA has wide powers throughout a court martial: ruling on questions, dealing with admissibility, controlling trial procedure, summing up the evidence and ensuring the proceedings are properly recorded.

Because these functions can materially affect the defence and the legal framework placed before the members, independence is not merely desirable—it is central to the fairness of the statutory process.

34. Nitin Shankar Kadkol: law is for the TJA, facts are for the court

In Nitin Shankar Kadkol v. Union of India, the Bombay High Court examined the statutory structure of Sections 99, 113 and 114. The decision reiterates that the TJA decides questions of law and lays down the law by which the court is guided.

This is useful when a dispute involves classification of an issue:

• limitation under the Navy Act is ordinarily a legal question for the TJA;
• admissibility is a legal question for the TJA;
• relevancy is a legal question for the TJA;
• credibility of a witness is ordinarily a factual question for the members; and
• whether the prosecution has proved guilt beyond reasonable doubt on the admitted evidence is ultimately for the court, applying the law stated by the TJA.

35. Commander V.S. Batra: TJA may decide limitation as a question of law

In Commander V.S. Batra v. Chief of the Naval Staff, the Delhi High Court considered a challenge involving Section 79 limitation. The court-martial record reflected the statutory division under Sections 114 and 115: the TJA dealt with the disputed question of law, while the president and members remained judges of fact.

The case illustrates that jurisdictional or limitation objections arising during trial should ordinarily be put before the TJA in a properly structured legal application and fully preserved in the record.

36. Santosh Karwade: contemporary application of the TJA’s legal-control role

In Santosh Karwade v. Union of India, the Kerala High Court considered an ongoing naval court martial and recognised the TJA’s statutory authority over questions of law, relevancy and admissibility.

The proceedings included a dispute over defence witnesses. The court examined whether the TJA had actually considered relevance and whether sufficient defence witnesses had been permitted rather than assuming that every rejected witness automatically amounted to denial of fair trial.

The case demonstrates an important litigation principle: a challenge to a TJA ruling is strongest when it shows precisely why the ruling was legally wrong, procedurally unfair or materially prejudicial.

37. Does every wrong TJA ruling invalidate the trial?

No. The legal consequence depends on the nature of the error.

Relevant questions include:

• Was the ruling on a mandatory jurisdictional safeguard?
• Did the TJA act outside the power conferred by the Act?
• Was relevant defence evidence wrongly excluded?
• Was inadmissible prejudicial material placed before the court?
• Was the court materially misdirected on the law?
• Did the TJA interfere with the members’ factual deliberation?
• Was there actual or apparent bias?
• Was the objection raised and preserved?
• Did the irregularity cause miscarriage of justice?

A jurisdictional breach, such as the one considered in Shivendra Bikaram Singh, may have a different legal consequence from a minor procedural defect that caused no prejudice.

38. How should a defence objection to a TJA ruling be framed?

A useful objection should contain:

1. the exact statutory or regulatory provision;
2. the ruling or conduct challenged;
3. the facts necessary to decide the issue;
4. the correct legal test;
5. the document or testimony affected;
6. the prejudice to the defence;
7. the precise relief requested; and
8. a request that the objection and ruling be fully recorded.

39. Challenging the appointment of the TJA

Where the objection concerns the TJA’s appointment or independence rather than a single ruling, the defence should obtain and examine:

• the appointment order or warrant;
• the TJA’s official posting and departmental status;
• the Convening Authority’s record concerning appointment;
• any request made for a departmental judge advocate;
• documents showing pre-trial advice by the proposed TJA;
• charge-sheet drafting correspondence;
• circumstantial-letter drafting correspondence;
• communications with the prosecutor;
• requests by the defence for change of TJA; and
• the written decision on such request.

40. What if the TJA remains present while members decide guilt?

Section 116(2) expressly excludes the TJA from the court’s deliberation on the finding.

Therefore, if the record shows that the TJA:

• remained in the deliberation room;
• answered questions privately during deliberation;
• communicated with members while they were considering guilt; or
• otherwise participated in the factual decision-making process,

the issue should be examined as a direct statutory violation.

41. TJA’s different role at the sentence stage

The same conduct is not automatically unlawful at the sentence stage because Section 120(2) expressly requires the TJA to sit with the court while punishment is considered.

The TJA may assist on the law of punishment but cannot vote. A challenge should therefore distinguish:

• lawful legal assistance on sentence;
• impermissible voting;
• pressure on members to impose a particular punishment; and
• use of legally irrelevant or inadmissible aggravating material.

42. Documents needed for a TJA legality audit

A complete review should collect:

• TJA appointment order or warrant;
• Regulation 161 appointment record;
• convening warrant;
• charge-sheet and circumstantial letter;
• pre-trial correspondence involving the TJA;
• notice of trial under Regulation 169;
• proof of supply of trial papers;
• requests and orders concerning defence witnesses;
• Section 101 opening proceedings;
• Section 102 and 103 objections;
• guilty-plea proceedings under Section 105, where applicable;
• orders on admissibility and relevance;
• orders on defence applications;
• no-case application and ruling;
• TJA summing up under Section 113;
• record showing withdrawal of the TJA during finding deliberations;
• finding under Sections 117–118;
• sentence proceedings under Sections 119–121;
• record of any defence objection alleging bias or excess of jurisdiction; and
• subsequent Section 160, Section 162 and AFT records.

43. A practical TJA challenge matrix

Issue	Provision	Document / record	Possible ground
Appointment	Section 99 / Reg. 161	Appointment warrant / nomination	Invalid appointment / bias
Member objection	Section 102	Opening minutes	TJA exceeded jurisdiction
Admissibility	Section 114	Evidence ruling	Wrong legal test / prejudice
Summing up	Section 113	TJA summing-up text	Misdirection on law
Finding deliberation	Section 116	Proceedings / attendance record	Improper participation
Sentence	Section 120	Sentence deliberation record	Vote / improper influence

44. Section 160 review and TJA errors

A legal error by the TJA should ordinarily be carried into the post-trial statutory record where it remains material.

A Section 160 application to JAG(N) may identify:

• wrong rulings on jurisdiction;
• inadmissible evidence admitted;
• relevant defence evidence excluded;
• misdirection in summing up;
• improper guilty-plea handling;
• failure to follow Section 102;
• bias or prior prosecution involvement; and
• unlawful participation in finding deliberations.

For the post-trial review structure, see Navy Act Section 160: JAG(N) Judicial Review.

45. Section 162 petition and TJA grounds

The same preserved errors may also be relevant in a petition against the finding or sentence under Section 162, particularly where the TJA’s ruling materially affected the conviction or punishment.

See Navy Act Section 162: Petition Against Court-Martial Finding or Sentence.

46. TJA errors in an AFT court-martial appeal

Section 15 of the Armed Forces Tribunal Act gives the AFT appellate jurisdiction over court-martial orders, decisions, findings and sentences.

A TJA ground before the AFT should identify:

• the exact ruling or conduct;
• the provision breached;
• the correct legal position;
• the objection made during trial, if any;
• the effect on admissible evidence or defence rights;
• the connection to the finding or sentence; and
• whether the defect caused miscarriage of justice or went to jurisdiction.

For the wider appellate route, see AFT filing, jurisdiction and court-martial appeals.

47. Frequently asked questions

Is a Trial Judge Advocate mandatory in every naval court martial?

Yes. Section 99 provides that every court martial shall be attended by a Trial Judge Advocate.

Must the TJA always be from the JAG(N) department?

Ordinarily a departmental judge advocate should be used where available. The statutory and regulatory scheme permits appointment of another fit person in the circumstances specified, with special protection for capital-offence trials.

Who decides questions of law in a naval court martial?

The TJA. Section 114 makes it the TJA’s duty to decide all questions of law arising during trial.

Who decides disputed facts?

The president and members of the court. Section 115 makes the court responsible for deciding which view of the facts is true and for arriving at the finding.

Can the TJA decide whether a witness is legally admissible?

Yes. Section 114 expressly covers relevancy and admissibility of evidence.

Can the TJA exclude inadmissible evidence even if defence counsel does not object?

Yes. Section 114 gives the TJA discretion to prevent production of inadmissible evidence whether or not a party has objected.

Can the TJA reject a bias objection against a court member?

The TJA may summarily reject an objection that is not based on the member’s competency to act impartially. But a genuine impartiality objection must be processed under Section 102; the TJA cannot decide its factual merits himself.

Does the TJA sit with the members when guilt is decided?

No. Section 116(2) expressly provides that the TJA shall not sit with the court while the finding is being considered.

Does the TJA sit with the members when sentence is decided?

Yes. Section 120(2) provides that the TJA sits with the court to assist on sentence but does not vote.

Can prior involvement in preparing the prosecution case create a bias issue?

Potentially, yes. The Delhi High Court in Avtar Singh treated extensive prior involvement in charge drafting, circumstantial-letter preparation and prosecution advice as a serious issue affecting TJA independence and impartiality.

Can a wrong TJA ruling be challenged before the AFT?

Yes, where the ruling or conduct affected legality of the proceedings, the finding, the sentence or caused miscarriage of justice within the AFT’s appellate jurisdiction.

Conclusion

The Trial Judge Advocate is one of the central legal safeguards in a naval court martial. Section 99 ensures that every court martial has a legal officer responsible for maintaining the statutory framework of the trial. Sections 101–121 then allocate to the TJA functions ranging from opening procedure and pleas to evidentiary rulings, legal applications, summing up, formalisation of findings and sentence assistance.

The most important structural rule is the distinction between law and fact. The TJA decides law; the members decide facts and guilt. The TJA must withdraw when the court deliberates on the finding but may sit during sentence deliberations only to assist and without voting.

Because the TJA exercises such extensive legal control, independence and impartiality are essential. A TJA who has materially participated in developing the prosecution case, exceeds statutory jurisdiction, admits inadmissible evidence, prevents relevant defence material, misdirects the court on law or improperly participates in factual deliberation may create substantial grounds for post-trial review and AFT appeal.
