What Is Unlawful Command Influence (UCI) and How Is It Addressed?

Unlawful command influence is the use of command authority, or any unauthorized means, to pressure the people who decide a court-martial: the members, the military judge, counsel, witnesses, or the convening and reviewing authorities. Article 37 of the Uniform Code of Military Justice (10 U.S.C. § 837) prohibits it. How a violation is remedied depends on when it happened. For violations on or after December 20, 2019, Article 37(c) allows a finding or sentence to be held incorrect on UCI grounds only if the violation “materially prejudices the substantial rights of the accused.”

Why the military treats it as a structural risk

The commander who convenes a court-martial can also hold authority over the evaluations and assignments of people who sit on it, testify in it, or advise on it; Article 37(b) addresses that overlap directly. The Court of Military Appeals called command influence “the mortal enemy of military justice” in United States v. Thomas, 22 M.J. 388, 393 (C.M.A. 1986), a phrase the Court of Appeals for the Armed Forces (CAAF) described in 2017 as “a canon of this Court’s jurisprudence” (United States v. Boyce).

What Article 37 prohibits

Article 37(a), as rewritten by the FY2020 National Defense Authorization Act, contains three prohibitions:

Censure of the court. No convening authority or other commanding officer “may censure, reprimand, or admonish the court or any member, military judge, or counsel thereof” about the findings, the sentence, or any other function in the proceeding (§ 837(a)(1)).
Deterring witnesses. No convening authority or other commanding officer “may deter or attempt to deter a potential witness from participating in the investigatory process or testifying at a court-martial.” Denying government-funded travel or refusing to make a witness available “shall not by itself” be UCI (§ 837(a)(2)).
Coercion or unauthorized influence. No person subject to the UCMJ “may attempt to coerce or, by any unauthorized means, attempt to influence” a court-martial or its members in reaching findings or sentence, or the action of any convening, approving, or reviewing authority or preliminary hearing officer (§ 837(a)(3)).

Article 37(b) adds a career protection: no one preparing an evaluation, promotion, assignment, or retention document may rate a member’s performance as a court-martial member, or rate a defense counsel lower “because of the zeal with which such member, as counsel, represented any person in a court-martial proceeding.”

The FY2020 law (Pub. L. 116-92, § 532) also renamed the section from “Unlawfully influencing action of court” to “Command influence” and added subsections (c) and (d). Its effective-date provision applies the changes to violations “committed on or after” December 20, 2019.

What the statute says is not UCI

Article 37(a)(4) lists examples of conduct that “may” fall outside the prohibitions:

general instructional or informational military justice courses designed solely to teach the substantive and procedural aspects of courts-martial;
statements about criminal activity or a particular offense “that do not advocate a particular disposition, or a particular court-martial finding or sentence, or do not relate to a particular accused”;
statements and instructions given in open court by the military judge or counsel.

Article 37(a)(5) allows a superior convening authority to “generally discuss matters to consider regarding the disposition” of offenses with a subordinate, and a subordinate to seek advice, but forbids directing “a particular disposition in a specific case”. Under Article 37(d), a superior may withhold a subordinate’s disposition authority in individual cases, types of cases, or generally, but otherwise may not limit the subordinate’s discretion in a case the subordinate has authority to dispose of.

The dividing line, then, is between general statements about misconduct and anything that reaches toward the outcome of a specific case or the independence of those deciding it.

Actual and apparent UCI under the earlier case law

Before the 2019 amendment, CAAF recognized two theories. Actual UCI required prejudice to the accused. Apparent UCI did not: in Boyce, the court held that “unlike actual unlawful command influence where prejudice to the accused is required, no such showing is required for a meritorious claim of an appearance of unlawful command influence.” The test was whether “an objective, disinterested observer, fully informed of all the facts and circumstances, would harbor a significant doubt about the fairness of the proceeding”, so that the conduct placed an “intolerable strain” on public perception of military justice.

Boyce involved a convening authority who referred charges after the Air Force Chief of Staff advised him that, unless he retired, the Secretary of the Air Force would fire him. CAAF reversed the findings and sentence without prejudice and authorized a rehearing.

The burden-shifting framework

Boyce also restated how a UCI claim is litigated:

The accused must first show “some evidence” that UCI occurred. The burden is low, but the evidence “must consist of more than ‘mere allegation or speculation.'”
The burden then shifts to the government to prove “beyond a reasonable doubt” either that the predicate facts do not exist or that the facts do not constitute UCI; under the earlier precedent the court quoted, the government could also show beyond a reasonable doubt that the UCI did not affect the findings and sentence.

What changed for violations on or after December 20, 2019

Article 37(c) now provides: “No finding or sentence of a court-martial may be held incorrect on the ground of a violation of this section unless the violation materially prejudices the substantial rights of the accused.” For violations on or after December 20, 2019, appearance alone, without material prejudice to the accused’s substantial rights, is not a statutory basis for holding a finding or sentence incorrect. The Boyce rule that apparent UCI needs no showing of prejudice to the individual accused describes the law for earlier violations. Article 37(c) speaks to whether a finding or sentence may be held incorrect; it does not by its terms limit the steps a military judge can take during trial to prevent or cure interference.

How UCI is detected and cured

At trial. CAAF describes military judges as the “sentinel” of the system in identifying and addressing UCI (Boyce). The defense raises it by motion, and members can be questioned during voir dire about pressure related to the case. Challenges for cause are part of how court-martial panel members are selected.

Remedies. CAAF’s digest of its UCI decisions records that dismissal of charges “is a drastic remedy” appropriate when an accused would be prejudiced or no useful purpose would be served by continuing, and that courts must look first for alternative remedies when the error can be rendered harmless. Remedies “must serve to protect the court-martial process and foster public confidence in the fairness of the military justice system”.

Waiver. A UCI claim can be waived. In United States v. Suarez, 86 M.J. 65, listed in CAAF’s digest under its 2024 term, the court held that the accused waived appellate review of his UCI claim by entering a plea agreement with a “waive all waivable motions” provision and affirming during the providence inquiry that he understood it; the court rejected the argument that adjudicative UCI (interference with witnesses, judges, members, or counsel) can never be waived. Waiver provisions are one of the terms negotiated in plea agreements in the military justice system.

UCI and the Office of Special Trial Counsel

For covered offenses committed after December 27, 2023, a special trial counsel, not a commander, has “exclusive authority” to refer, dismiss, and enter plea agreements on those charges (10 U.S.C. § 824a(c)(3)). That moves the referral decision in those cases out of the chain of command; the convening authority’s remaining role is covered in the convening authority’s role in the court-martial process. Article 37 still applies throughout, including to anyone who attempts to influence the special trial counsel’s or the court-martial’s actions by unauthorized means.
