What Major Reforms Has Congress Enacted to the Military Justice System in Recent Years?

A service member or family member who reads a court-martial guide written five years ago will find a system that no longer exists in several important respects. Who decides to prosecute a sexual assault, who imposes the sentence, how many members sit on a panel, and what a plea agreement binds have all changed by act of Congress since 2014. The driving force has been a decade of legislative pressure over how the armed forces handle sexual assault and over the concentration of charging power in commanders. The result is not a single reform but a layered sequence, each piece with its own effective date. This guide maps the recent reforms one at a time: what changed, when it took effect, and why Congress made the change.

A reform built on dates, not just statutes

The single most useful thing to understand about recent military justice reform is that it is governed by effective dates, not enactment dates. Congress routinely passes a change in one December and delays its operation by a year or more, and it usually applies the change only to offenses committed after the operative date. That produces a system running on parallel tracks: an older case proceeds under the rules that existed when the conduct occurred, while a newer case proceeds under the reformed rules. The first question in any reform analysis is therefore the date of the alleged offense.

The Military Justice Improvement Act: the proposal that set the agenda

Senator Kirsten Gillibrand’s Military Justice Improvement Act was never enacted in full, but it shaped much of what followed. The proposal would have removed the decision to prosecute serious offenses from commanders entirely and given it to independent military lawyers outside the chain of command. For years it fell short of the votes to pass as a standalone measure, but it reframed the debate: the question stopped being whether to adjust commander discretion at the margins and became whether commanders should hold charging power over serious crimes at all. The structural reform Congress did enact in 2021 adopted the core of that idea for a defined set of offenses.

The FY2014 NDAA: narrowing two longstanding command powers

The National Defense Authorization Act for Fiscal Year 2014, signed in December 2013, made two changes that are easy to overlook because later reforms were larger, but that altered the procedural landscape.

First, it converted the Article 32 proceeding from a broad pretrial investigation into a narrower preliminary hearing. The proceeding had functioned partly as a discovery tool in which the defense could examine witnesses at length about the underlying facts; the reform refocused it on probable cause, jurisdiction, the form of the charges, and a disposition recommendation, and the practical effect was a sharp drop in live witness testimony. The driver was concern that complaining witnesses in sexual assault cases were being subjected to extensive cross-examination before trial.

Second, the FY2014 NDAA sharply limited the convening authority’s clemency power under Article 60. A commander had long been able to set aside a finding of guilt or reduce a sentence after trial. The reform stripped that power for most serious offenses, ending the ability to disapprove a finding of guilt or to reduce most punitive discharges and longer confinement terms. It was the first major curtailment of post-trial command discretion, and later reforms continued in the same direction.

The 2015 narrowing of the good-soldier defense

Acting under the FY2015 NDAA, the President signed Executive Order 13696 on 17 June 2015, amending Military Rule of Evidence 404(a). The amendment provides that a service member’s general military character is not a pertinent trait for showing the probability of innocence for an enumerated set of offenses, including sexual assault charges under Article 120. For decades the so-called good-soldier defense had let an accused offer evidence of exemplary service as circumstantial proof of innocence. After 2015 that evidence remains available for offenses where military character is genuinely relevant, such as certain duty-related and integrity offenses, but not for the listed crimes, on the judgment that a strong service record has little bearing on whether a particular sexual assault occurred.

The Military Justice Act of 2016: the structural rebuild, effective 1 January 2019

The Military Justice Act of 2016, enacted as part of the FY2017 NDAA, was the most comprehensive overhaul of the system since the Uniform Code of Military Justice took effect in 1951. Although signed in December 2016, it took effect on 1 January 2019, and several of its changes define how courts-martial operate today.

It fixed panel sizes that had previously been described as minimums. A general court-martial now seats eight members, a capital general court-martial seats twelve, and a special court-martial seats four, and the accused may instead elect trial by military judge alone for findings. It created Article 53a plea agreements, which bind the court-martial within the limits the parties set, replacing the older pretrial-agreement framework. And it carried out a sweeping renumbering of the punitive articles, which is why an older charge sheet or guide may cite an article number that now points to a different offense. Espionage, for example, moved from Article 106a to Article 103a, and drunken or reckless operation of a vehicle moved from Article 111 to Article 113. A reader comparing a recent charge to an older reference has to account for this renumbering or risk reading the wrong statute.

The FY2022 NDAA: independent prosecutors and judge-imposed sentencing

The FY2022 NDAA, signed 27 December 2021, produced the two largest structural reforms of the modern era. Both took effect for covered conduct on 27 December 2023, with the prosecution offices reaching full operating capability on 28 December 2023.

The Office of Special Trial Counsel

The first reform created the Office of Special Trial Counsel in each service, codified at Article 24a (10 U.S.C. 824a). Special trial counsel are specially trained military lawyers who hold exclusive authority over a defined list of serious crimes called covered offenses. For those offenses, the commander no longer decides whether to prosecute. The special trial counsel determines whether a reported offense qualifies, makes the binding referral decision to a general or special court-martial, enters into plea agreements on the government’s behalf, and withdraws or dismisses charges. These four authorities had belonged to convening authorities for the entire prior history of the code, which is what makes this the most significant shift in the system since 1951.

The independence of the office is deliberate. Each service’s lead special trial counsel is a general or flag officer who, by statute, reports to the service Secretary rather than through the Judge Advocate General or any operational commander, and the office’s personnel are independent of the chains of command of both the accused and the victim. The covered offenses initially numbered thirteen categories, including murder, manslaughter, kidnapping, domestic violence, stalking, child-pornography offenses, the wrongful distribution of intimate visual images under Article 117a, and most sexual offenses under the Article 120 series. The standalone offense of sexual harassment under Article 134 was added as a covered offense effective 1 January 2025, expanding the list to fourteen categories. The delay let the new offices build reporting and intake procedures before taking on that caseload.

A distinctive feature of the office is its reach-back authority, the power to take over qualifying cases that arose before it stood up, including matters that commanders had previously handled or declined to pursue. As a documented illustration of scale, the Army’s Office of Special Trial Counsel, headquartered at Fort Belvoir, Virginia, reported through mid-October 2024 that it had reviewed roughly 3,300 cases and referred about 180 to court-martial, of which roughly 113 were reach-back cases predating its December 2023 launch. Those figures are a point-in-time snapshot rather than a fixed total, and the office’s caseload has continued to grow since.

Military judge sentencing

The second FY2022 reform, in Section 539E, changed who imposes sentences. For non-capital offenses committed on or after 27 December 2023, the military judge alone determines the sentence, even when members decide guilt. This ended the accused’s longstanding option to be sentenced by panel members, which had been regarded as a meaningful protection. Capital cases are the exception: members still sentence in a death-penalty case.

The reform paired judge sentencing with a structured framework. The 2024 Manual for Courts-Martial sets out sentencing parameters and criteria that group offenses into categories with associated confinement ranges. For parameter offenses the judge sentences within the designated range absent articulated findings that justify a departure; for criteria offenses the guidance is advisory. The model resembles the structured approach of the federal civilian sentencing guidelines while preserving judicial discretion through the departure mechanism. Because the new system applies only to conduct on or after 27 December 2023, the older discretionary regime continues to govern pre-reform cases, and the two systems will run side by side for years as older cases finish moving through trial and appeal.

Smaller reforms in the same direction

Several less prominent changes accompanied the headline reforms and point the same way, toward independence and consistency. Congress moved toward more structured, less hand-picked panel selection to address longstanding concern about the appearance of command influence over who sits in judgment, while keeping the Article 25 qualification criteria. It directed the services to study and report on racial and other demographic disparities in charging, panel composition, and sentencing, and annual military justice reports now carry that data. It expanded victims’ rights, building on the Special Victims’ Counsel and Victims’ Legal Counsel programs that give victims independent representation and the rights to be informed of and present at proceedings, to submit impact statements, and to confer with the prosecution. And it adjusted parts of the appellate process, including the scope of automatic review and the handling of sentence appeals, to address chronic post-trial delay. Each is narrower than the OSTC or judge-sentencing reforms, but together they extend the same logic of reducing unilateral command discretion.

What remains under debate

The reform debate has not closed. Proposals continue to circulate to widen the Office of Special Trial Counsel’s jurisdiction to additional offenses, to require unanimous verdicts for serious crimes rather than the current three-fourths threshold, to further limit the convening authority’s residual role, and to strengthen defense resourcing so that it keeps pace with the new prosecution offices. These proposals reflect the unresolved tension at the center of the whole reform project: how to preserve a commander’s responsibility for discipline while building a prosecution function independent enough to command public confidence. Where the line finally settles is still being negotiated.
