Arraignment in the Military Justice System: Charges, Pleas, and Forum
On this page
Arraignment is short and it fixes things. The charges are read or waived, a plea is entered, and the choices that shape the rest of the case become available. The Uniform Code of Military Justice does not describe the ceremony; it describes what a plea does, who may agree to what, and which decisions must be made before the court is assembled.
This page covers the three things the title names. What arraignment is in the Code’s scheme, what a plea of guilty accomplishes and what it cannot be received for, and the forum choices the accused holds, each with its own deadline.
It does not advise on any plea or any forum choice. Both are decisions with consequences that depend on the case.
Where arraignment sits
Arraignment is one of the functions the Code assigns to a session held without the members present.
“(3) holding the arraignment and receiving the pleas of the accused”
Source: 10 U.S.C. 839 (Article 39), subsection (a)(3).
Those sessions are available “at any time after the service of charges which have been referred for trial”, subject to Article 35. So arraignment comes after referral and after service, and it happens before a panel exists in the courtroom. Who must attend is fixed by Article 39(b): the accused, the defense counsel, and trial counsel.
Arraignment also matters for the Article 35 waiting period, and the period is worth reading in the statute’s own words, because the shorthand version of it describes a different span.
“(1) Subject to paragraphs (2) and (3), no trial or other proceeding of a general court-martial or a special court-martial (including any session under section 839(a) of this title (article 39(a)) may be held over the objection of the accused— (A) with respect to a general court-martial, from the time of service through the fifth day after the date of service; or (B) with respect to a special court-martial, from the time of service through the third day after the date of service.”
Source: 10 U.S.C. 835 (Article 35), subsection (b)(1).
Three points follow. The protected window runs from service through the fifth day after the date of service for a general court-martial and through the third for a special one, which is not the same span as “five days from service”. The objection may be raised “only at the first session of the trial or other proceeding and only if the first session occurs before the end of the applicable period”, and where it does the judge “shall, at that session, inquire as to whether the defense objects under this subsection.” And subsection (b)(3) removes the whole protection in one circumstance: it “shall not apply in time of war.”
What a plea of guilty does
Article 45(b) gives a guilty plea a specific procedural effect, and imposes one absolute bar.
“(b) Pleas of Guilty.—A plea of guilty by the accused may not be received to any charge or specification alleging an offense for which the death penalty is mandatory. With respect to any other charge or specification to which a plea of guilty has been made by the accused and accepted by the military judge, a finding of guilty of the charge or specification may be entered immediately without vote. This finding shall constitute the finding of the court unless the plea of guilty is withdrawn prior to announcement of the sentence, in which event the proceedings shall continue as though the accused had pleaded not guilty.”
Source: 10 U.S.C. 845 (Article 45), subsection (b).
Four things are in that passage. A guilty plea cannot be received where the death penalty is mandatory. Where accepted, a finding may be entered immediately and without a vote, which is why Article 52(a)(1) lists a guilty plea as an exception to the three-fourths rule. The finding is the finding of the court. And withdrawal is possible before announcement of the sentence, after which the proceedings continue as if the plea had been not guilty.
When a plea will not be accepted
Article 45(a) lists the circumstances in which the court enters a not-guilty plea regardless of what the accused said.
“(a) Irregular and Similar Pleas.—If an accused after arraignment makes an irregular pleading, or after a plea of guilty sets up matter inconsistent with the plea, or if it appears that he has entered the plea of guilty improvidently or through lack of understanding of its meaning and effect, or if he fails or refuses to plead, a plea of not guilty shall be entered in the record, and the court shall proceed as though he had pleaded not guilty.”
Source: 10 U.S.C. 845 (Article 45), subsection (a).
Five triggers: an irregular pleading, matter inconsistent with the plea, an improvident plea, lack of understanding of its meaning and effect, and failure or refusal to plead. In each case the remedy is the same and it is automatic.
Article 45(c) then sets the standard for errors under the article: a variance is harmless “if the variance does not materially prejudice the substantial rights of the accused.”
Plea agreements, and who may sign one
Article 53a permits agreement on disposition and on sentence limits, with a timing limit and two structural restrictions.
“(a) In General.—(1) Subject to paragraph (3), at any time before the announcement of findings under section 853 of this title (article 53), the convening authority and the accused may enter into a plea agreement with respect to such matters as— (A) the manner in which the convening authority will dispose of one or more charges and specifications; and (B) limitations on the sentence that may be adjudged for one or more charges and specifications.”
Source: 10 U.S.C. 853a (Article 53a), subsection (a)(1).
The first restriction keeps the judge out of the bargaining: “The military judge of a general or special court-martial may not participate in discussions between the parties concerning prospective terms and conditions of a plea agreement.”
The second reflects the reallocation of prosecutorial authority:
“(3) With respect to charges and specifications over which a special trial counsel exercises authority pursuant to section 824a of this title (article 24a), a plea agreement under this section may only be entered into between a special trial counsel and the accused.”
Source: 10 U.S.C. 853a (Article 53a), subsection (a)(3).
For covered offenses the commander is not a party to the agreement. Who holds that authority and why is in convening authority.
Acceptance is the judge’s, and the default runs toward accepting. Under subsection (b), the judge “shall accept a plea agreement submitted by the parties”, subject to exceptions that include cases where an offense has a sentencing parameter prescribed by the President.
Forum, and the deadlines on choosing
Two forum choices belong to the accused, and both must be made before the court is assembled.
Judge alone. Article 16 permits a general or special court-martial composed of a military judge alone where the accused, “before the court is assembled”, knowing the identity of the judge and “after consultation with defense counsel”, requests it orally on the record or in writing, and the judge approves.
Panel composition, for an enlisted accused. Article 25(c)(2) allows an enlisted accused, before assembly, to personally request a panel entirely of officers, or one in which enlisted members are at least one-third of the membership.
Both are personal, both are on the record or in writing, and both close at assembly.
The Manual sets the form of the judge-alone election, and the Army’s criminal law deskbook states it: “Trial by judge alone may be elected or requested orally or in writing by the accused. If the request is made in writing, it must be signed by the accused.”
Source: Criminal Law Deskbook, Court-Martial Personnel, on R.C.M. 903. This is the deskbook’s statement of the rule rather than the text of the rule.
Two details in that. The election may be oral, so a written document is not a precondition. And where it is written, the accused signs it, not counsel.
Three things sit close together here and they are not the same thing. Forum election runs under R.C.M. 903, arraignment under R.C.M. 904, and the mechanics of a plea under R.C.M. 910. None of those three rules was opened for this page. They are named so that a reader who needs the procedure knows which one to look for, and so that nothing here is mistaken for all three at once. The mechanics of panel selection that follow are in how a court-martial panel is chosen.
What forum does not decide any more
Choosing a panel no longer means choosing who sentences. Under Article 25(d)(1), in a court-martial with a judge and members the accused “shall be sentenced by the military judge”, with capital cases excepted. Sentencing sits with the judge in either forum.
What this page does not decide
Whether to plead guilty, or whether to seek an agreement. Article 45(b) states what a plea accomplishes procedurally; what it means for a person is a different question.
Whether a plea was provident. Article 45(a) gives the court a duty to enter a not-guilty plea in listed circumstances, and whether one applies is decided on the record.
What sentencing parameters apply. They are prescribed in regulations under Article 53a(b), which this page did not open.
Where to go from here
What happens after the plea is entered is in inside a court-martial trial, and the motions that are heard at the same kind of session are in pretrial motions. For everything that precedes arraignment, see what happens before a court-martial.

Checked on 19 September 2026, and checked for currency as well as for accuracy. Every statutory provision cited on this page was traced to the current United States Code: where a provision has not been amended since the 2023 edition, that edition’s text is the current text and its amendment record was read to confirm it; where a provision was amended by Pub. L. 118–159 (23 December 2024) or Pub. L. 119–60 (18 December 2025), the current text is quoted above and the amending Act is named beside it. The two Acts’ own texts were read to establish the complete list of provisions in this chapter that they changed. This was done through the Cornell mirror of the Code and through the Acts as published by the Government Publishing Office; the House preliminary Code could not be reached from here, so no third source confirms it. No independent expert review has taken place yet, and this page says so rather than implying one.
