Under Article I, sec. 8 of the U.S. Constitution, Congress has the power to raise and support armies; provide for and maintain a navy; and to provide for organizing and disciplining them. Under this authority, the Congress has enacted the Uniform Code of Military Justice (UCMJ), the code of military criminal laws applicable to all military members worldwide. The President implemented the UCMJ through the Manual for Courts-Martial (MCM), which was prescribed by Executive Order 12473 (April 13, 1984). The MCM contains the Rules for Courts-Martial (RCM), the Military Rules of Evidence (MRE), and the UCMJ. The MCM covers almost all aspects of military law. Military criminal trial courts are known as courts-martial. Military courts are not considered Article III courts but instead are established pursuant to Article I of the Constitution.
A court-martial has always been an ad hoc tribunal created and appointed by the order of a commander, called the convening authority, for the express purpose of considering a set of charges that the commander has referred to the court. The convening authority personally selects the "best qualified" members of a court-martial panel, who are generally members of the command.
Courts-martial are adversarial proceedings, as are all U.S. criminal courts. That is, lawyers representing the government and lawyers representing the accused present the facts and legal arguments most favorably to their own respective side; a military judge determines questions of law, and the members of the panel (or military judge in a judge-alone case) determine questions of fact.
A conviction at a general court-martial is equivalent to a civilian conviction in a federal district court. Special courts-martial are considered "federal misdemeanor courts" because they cannot impose confinement longer than one year. Nevertheless, a conviction at a special court-martial is still considered a federal conviction. Summary courts-martial and nonjudicial punishment have no civilian counterpart, and a determination of guilt at these forums is not considered a federal conviction.
Jurisdiction of Courts-Martial
In order to be tried by a court-martial, the court-martial must have jurisdiction over the person. Jurisdiction of a court-martial does not depend on where the offense was committed. Rather, it depends solely on the status of the accused as a member of the armed forces on active duty, whether in the regular or reserve component. In addition to service members, several other categories of individuals may be tried by courts-martial including retired members of a regular component of the armed forces entitled to pay; retired members of a reserve component who are hospitalized in a military hospital; persons in custody of the military serving a sentence imposed by a court-martial; members of the National Oceanic and Atmospheric Administration and Public Health Service and other organizations, when assigned to serve with the military; enemy prisoners of war in custody of the military; and persons with or accompanying the military in the field during "times of war," limited to declared wars.
Types of Offenses
Courts-martial try "military offenses," which are listed in the punitive articles of the UCMJ and are codified in 10 U.S.C. 877 et seq. Some "military offenses" have a civilian analog, but a number of "military offenses" are specific to the military. The President is authorized to prescribe the punishments which a court-martial may impose within the limits established by Congress. In addition, a service member may be tried at a court-martial for offenses not specifically covered by the UCMJ. Article 134–General Article states that all "crimes and offenses not capital, of which persons subject to this chapter may be guilty, shall be taken cognizance of by a general, special, or summary court-martial, according to the nature and degree of the offense." This means that any state or federal offense for which there is no analogous crime in the UCMJ may be assimilated and tried at a court-martial. The potential punishments for violations of Article 134 are the same as the punishments applicable to the corresponding civilian offense.
Investigation and Suspect Rights
When a service member has reportedly committed an offense, the accused's immediate commander will conduct an inquiry into the alleged offense. This inquiry will vary according to the offense(s) alleged and the complexity of the case. It may range from an examination of the charges and an investigative report or summary of expected evidence to a more extensive investigation. The investigation may be conducted by members of the command or, in more complex cases, military and civilian law enforcement officials. Once evidence has been gathered and the inquiry is complete, the commander can choose to dispose of the charges by (1) taking no action, (2) initiating administrative action, (3) imposing nonjudicial punishment, (4) preferring charges, or (5) forwarding to a higher authority for preferral of charges.
Pursuant to Article 31, UCMJ (10 U.S.C. § 831), service members have a right against self-incrimination and are entitled to be informed of the suspected offense(s) before questioning begins. In addition to protections against self-incrimination, service members suspected of committing an offense have a right to military counsel when questioned, upon preferral of charges, and/or upon initiation of arrest or apprehension. These rights and protections apply whenever the service member is questioned as a suspect of an offense.
Article 31, UCMJ rights include two important components. First, no one subject to the Uniform Code of Military Justice may compel any other service member to incriminate himself, or to answer any question where the answer may tend to incriminate the service member. Second, no person subject to the UCMJ may interrogate, or request any statement from a person suspected of an offense without first informing him of the nature of the accusation, that he does not have to make a statement regarding the offense, and that any statement may be used against him as evidence in a trial by court-martial.
Military defense counsel is provided free of charge regardless of the accused's ability to pay. The accused may also employ civilian counsel at his own expense, or request a particular military counsel, who will assist the accused if reasonably available. The accused has the right to be represented by counsel at the magistrate hearing when a determination is made regarding continued pretrial confinement, during the Article 32, UCMJ investigation, and during all court-martial sessions. After trial, the accused has a right to free military counsel to assist with his appeal through the military appellate courts, and potentially to the U.S. Supreme Court.
Formal Initiation of Charges
Preferral of charges is the first formal step in a court-martial. Preferral of charges consists of drafting a charge sheet containing the charges and specifications against the accused. The charge sheet must be signed by the accuser under oath before a commissioned officer authorized to administer oaths. Once charges have been preferred they may be referred to one of three types of courts-martial: summary, special or general. The seriousness of the offenses alleged generally determines the type of court-martial. The court-martial must be convened by the convening authority, who will generally be the commissioned officer, or successor, in command of the unit to which the accused is attached.
Types of Courts-Martial
Summary Courts-Martial. The summary court-martial can adjudicate minor offenses allegedly committed by enlisted service members. It can adjudge maximum punishments of thirty days confinement, hard labor without confinement for 45 days, restriction to specified limits for 45 days, forfeiture of two-thirds pay per month for one month, and reduction to the lowest pay grade. In the case of enlisted members above pay grade E-4, the summary court-martial may not adjudge confinement or hard labor without confinement and can only reduce them to the next lower pay grade. Summary courts-martial are composed of one commissioned officer who need not be a lawyer. The accused must consent to the proceedings and normally is not entitled to a lawyer. Military service members who refuse Article 15, UCMJ nonjudicial punishment can be referred for summary court-martial, but they can also refuse this forum.
Special Courts-Martial. The special court-martial is the intermediate court level. A special court-martial can try any service member for any non capital offense or, under presidential regulation, capital offenses. This court-martial can be composed of a military judge alone, not less than three members, or a military judge and not less than three members. Contrary to civilian criminal trials, only two-thirds of the members of a court-martial need to agree as to the guilt of the accused for the accused to be found guilty. Otherwise, the accused is acquitted. There are no "hung juries" in courts-martial. Regardless of the offenses tried, the maximum punishment allowed at a special
court-martial is confinement for one year, hard labor without confinement for up to three months, forfeiture of two-thirds pay per month for up to one year, reduction in pay grade, and a bad-conduct discharge. An officer accused at a special court-martial cannot be dismissed from the service or confined. Most often, special courts-martial will try offenses considered misdemeanors. The accused is entitled to an appointed military attorney, a military counsel of his selection, or the accused can hire a civilian counsel at no expense to the government.
General Courts-Martial. A general court-martial is the highest trial level in military law and is usually reserved for the most serious offenses. It is composed of a military judge sitting alone, or at least five members and a military judge. It can adjudge, within the
limits prescribed for each offense, a wide range of punishments to include confinement, reprimand, forfeitures of up to all pay and allowances, reduction to the lowest enlisted paygrade, punitive discharge (bad conduct discharge, dishonorable discharge or dismissal), restriction, fines and, for certain offenses, death. The accused is entitled to an appointed military attorney or a military counsel of his or her selection, or the accused
can hire a civilian counsel at no expense to the government. Prior to the convening of a general court-martial, a pretrial investigation, more commonly known as the Article 32 hearing, must be conducted.
The Article 32 hearing is the equivalent of a civilian grand jury, meant to assess the truth of the charges to ensure that there is a basis for prosecution. An investigating officer, who must be a commissioned officer, presides, and the accused has the same entitlements to counsel as in a special courts-martial. However, unlike in a civilian grand jury investigation where the accused has no access to the proceedings, the accused is afforded the opportunity to examine the evidence presented against him, cross-examine witnesses and present his own arguments. If during the course of the investigation evidence surfaces that the accused committed an offense not charged, the investigating officer can recommend that more charges be brought against the accused. Likewise, if the investigating officer believes that there is not enough evidence to support a charge, he can recommend that it be dismissed. Once the Article 32 investigation is complete, the investigating officer will make recommendations to the convening authority via the convening authority's legal advisor. The legal advisor, in turn, provides the convening authority with formal written advice, known as the Article 34, UCMJ advice, as to the appropriate disposition of charges. The convening authority then determines whether to convene a court-martial or dismiss the charges.
One of the unique aspects of the military justice system is the post-trial review by the convening authority. For convictions at a general or special court-martial that include a punitive discharge, the process starts with the review of the staff judge advocate (SJA), and a recommendation to the convening authority as to what action to take on the case. This is recognized as the accused's best hope for relief as the convening authority has broad powers to act on the case. Upon review of the record of trial and the SJA's recommendation, the convening authority may, among other remedies, suspend all or part of the sentence, disapprove a finding or conviction, or lessen the sentence. The convening authority may not increase the sentence. Once the convening authority takes action on the case, the conviction is ripe for an appeal. In the case of summary court-martial or a court-martial where the service appellate courts do not have jurisdiction, convictions will be reviewed by a judge advocate to determine if the findings and sentence, as approved by the convening authority, are correct in law and fact. If those criteria are met, the conviction is final. If not, the judge advocate will forward the case to a general court-martial convening authority for corrective action. If the convening authority refuses to take corrective action, the case is referred to the Judge Advocate General for review.
Convictions by a special or general court-martial are subject to an automatic appeal to a service Court of Criminal Appeals if the sentence includes confinement for one year or more, a bad-conduct or dishonorable discharge, death, or a dismissal in the case of a commissioned officer, cadet or midshipman. Appeal is mandatory when the sentence includes death. If the conviction is affirmed by the service court, the appellant may request review by the Court of Appeals for the Armed Forces and ultimately the U.S. Supreme Court. Review by these courts is discretionary.
