Whether you are in the Army, Air Force, Space Force, Navy, Marine Corps, or Coast Guard, convening authorities operate in a very similar manner in sending criminal cases to court-martial.
Who Has the Power to Convene a Court-Martial?
In the military justice system, one of the most consequential roles isn’t held by a judge or a lawyer; it’s held by the convening authority. This person, often a commanding officer, holds the legal power to initiate, refer, and review courts-martial under the Uniform Code of Military Justice (UCMJ). For members of the Armed Forces, understanding who has this authority—and how it can shape the outcome of a trial—is critical.
Recent changes, including the creation of the Office of Special Trial Counsel (OSTC), have changed how some offenses are handled, especially those involving sexual misconduct or domestic violence. This guide outlines the role of both command-based convening authorities and independent legal offices like the OSTC, covering how special, general, and summary courts-martial are convened and what legal protections are available for service members.
What Is a Convening Authority in the Military?
A convening authority is a senior official, usually a commissioned officer in command, who is legally authorized by the President to assemble a court-martial. Under Article 22 of the UCMJ, this authority may also be delegated to select officials within the Department of Defense (DoD), including secretarial-level positions, such as the Secretary of Defense or War Secretary.
The convening authority decides which type of court-martial is appropriate: summary, special, or general. They are responsible for the referral of charges and may be involved throughout the pretrial, trial, and post-trial phases.
Although not a courtroom participant, the convening authority is one of the most powerful actors in the entire military justice system, particularly when it comes to deciding if a case moves forward at all.
Types of Courts-Martial and Their Convening Authorities
Military law recognizes three kinds of courts-martial, each with its own level of severity, sentencing power, and convening process.
Summary Court-Martial
- Handles minor offenses
- Comprised of one commissioned officer acting as judge and fact-finder
- Maximum punishment includes 30 days confinement, hard labor, or forfeiture of pay
- Often convened by lower-level commanders
- Not suitable for more serious allegations or complex cases
Special Court-Martial
- Similar in structure to a misdemeanor court in civilian law
- Consists of a military judge and at least four panel members, or judge alone if requested by the accused
- Can impose up to 12 months’ confinement, bad conduct discharge, and reduced pay
- Convened by a Special Court-Martial Convening Authority (SPCMCA), often a battalion or wing-level commanding officer
General Court-Martial
- Used for felony-level offenses under the UCMJ
- Includes a military judge, at least eight members, or a judge alone if requested
- Can impose the maximum sentence under military law, including dishonorable discharge, life imprisonment, or death in rare cases
- Initiated by a General Court-Martial Convening Authority (GCMCA), typically a commanding general, base commander, or higher-ranking official
In each case, the referral decision must be made following a thorough review of the evidence, often based on recommendations from legal advisors.
The Office of Special Trial Counsel (OSTC): Independent Convening for Covered Offenses
The Office of Special Trial Counsel was established as a response to long-standing concerns about potential conflicts of interest when commanding officers acted as both accusers and legal authorities in sensitive cases. The OSTC provides an independent referral mechanism for a category of “covered offenses,” primarily involving:
- Sexual assault
- Rape
- Domestic violence
- Child abuse
Unlike command-based convening authorities, OSTC attorneys:
- Operate independently of the chain of command
- Are trained trial counsel with specific prosecutorial authority
- Apply consistent standards of review based on military law, evidence, and victim rights
For these covered offenses, commanding officers no longer control the referral or initiation of the court-martial process, though they may still have administrative duties.
This change helps safeguard the rights of the accused while reinforcing public trust in the military justice system.
Responsibilities of a Convening Authority Under the UCMJ
The Manual for Courts-Martial (MCM) and Rules for Courts-Martial (R.C.M.) outline the formal duties of a convening authority. These include:
- Referring charges to the appropriate type of court-martial
- Selecting members of the court-martial panel (jury) from qualified military personnel
- Approving or disapproving pretrial plea agreements
- Reviewing the record of the trial for legal and procedural errors
- Authorizing a rehearing when appropriate
- Making post-trial decisions related to the sentence of a court-martial, such as reducing or eliminating forfeiture, hard labor, or punitive discharges
The staff judge advocate (SJA) provides legal advice to the convening authority at each phase, helping interpret the rules of evidence, assess the strength of the case, and ensure compliance with applicable United States Code (U.S.C.) and military directives.
Convening Authority vs. Judicial Authority
While the convening authority initiates and supports the court-martial process, they do not act as judge or jury. That responsibility lies with the:
- Military judge – Presides over the trial, rules on motions, and ensures procedural compliance
- Court-martial members – Commissioned officers (and sometimes enlisted personnel) who serve as the jury
- Trial counsel – Prosecutor representing the government
- Defense counsel – May be a JAG-assigned attorney or a civilian military defense lawyer
This separation of powers preserves the integrity of the process and ensures active duty service members receive a fair trial.
Post-Trial Review and Appeals
After sentencing, the convening authority conducts a post-trial review, which includes:
- Reviewing the finding of guilty
- Determining whether the sentence is legally sufficient
- Making any authorized sentence reductions (e.g., bad conduct discharge delay or cancellation)
- Deciding whether to approve or disapprove confinement, forfeiture, or rehearing
However, certain cases—especially those involving confinement over six months or a punitive discharge—are automatically reviewed by a Court of Criminal Appeals, and potentially the Court of Appeals for the Armed Forces or even the Supreme Court.
These appellate courts review for legal errors, violations of constitutional rights, and inconsistencies in the application of military justice.
When Should a Service Member Speak to a Defense Counsel?
Any service member facing charges under the UCMJ should consult a defense counsel immediately. While the military provides assigned counsel through the Judge Advocate General (JAG) Corps, you have the right to retain a civilian attorney.
A civilian military defense lawyer can:
- Challenge the referral of charges
- Negotiate favorable outcomes during the pretrial phase
- Argue for diversion programs or nonjudicial punishment instead of court-martial
- Prepare detailed defenses rooted in the rules of evidence, case law, and subsection-specific regulations
Many law school graduates who specialize in military law have dedicated their careers to defending the accused in complex court-martial cases, both at trial and on appeal.
Know Your Rights and Who Holds the Power
The convening authority plays a central role in determining whether a case goes to court-martial and what kind of trial it will be. With the emergence of the Office of Special Trial Counsel, members of the Armed Forces now face two parallel systems—one rooted in command, the other in legal independence.
If you’re under investigation or facing possible charges, the first decisions made in your case may shape your entire future.
