Sentencing Parameters and Criteria After the 2023 Military Justice Reforms
Key takeaways
- For non-capital offenses on or after December 27, 2023, the military judge sentences in every court-martial — the panel’s role ends at findings.
- Where parameters apply, the judge must sentence within them unless specific facts warrant a departure — and a departure requires a written statement of its factual basis. R.C.M. 1002.
- An accepted plea agreement’s sentence limitation still binds the court — but the judge may refuse a proposed sentence, inside the parameters or not, that is plainly unreasonable.
- Judge-adjudged sentences are now segmented: confinement and fines are specified for each offense, with consecutive-or-concurrent designations. United States v. Flores, 84 M.J. 277 (C.A.A.F. 2024).
- Mandatory minimums and the offense-by-offense maximums of the Manual still frame everything the parameters do.
What the NDAA 2022 reforms changed
The National Defense Authorization Act for Fiscal Year 2022 worked the deepest change to court-martial sentencing since the UCMJ was enacted. It arrived alongside the creation of the Office of Special Trial Counsel, but its sentencing provisions reach every kind of case, not just covered offenses. Two moves matter most: sentencing authority shifted to the military judge in all non-capital cases, and the judge’s discretion was channeled through sentencing parameters and criteria applicable to particular offenses.
The old system asked a panel — or a judge, if the accused elected judge-alone — to pick any lawful sentence between zero and the maximum, with almost no structure in between. The new system gives the sentencing judge lanes to drive in and reasons to give for leaving them. R.C.M. 1002 carries the framework.
Judge-alone sentencing: the December 27, 2023 line
The dividing line is the date of the offense. For any non-capital court-martial trying offenses committed on or after December 27, 2023, the accused is sentenced by the military judge, regardless of the forum that decided findings. A panel may still convict; only the judge sentences. R.C.M. 1002.
| Offenses before Dec. 27, 2023 | Offenses on or after Dec. 27, 2023 (non-capital) | |
|---|---|---|
| Sentencing authority | Panel (unless judge-alone elected) | Military judge in every case |
| Form of sentence | Panel: single unitary sentence for all offenses | Segmented — confinement and fines specified per offense |
| Structure of discretion | Zero to the maximum | Parameters and criteria where applicable; written statement for departures |
| Voting | Three-fourths of members (unanimous for death) | No vote — the judge decides |
Capital cases stay with members, where death requires unanimous concurrence on findings, an aggravating factor, the weighing of circumstances, and the sentence itself. R.C.M. 1004. And in legacy cases panels still return one undivided sentence, adopted by at least three-fourths of the members.
Parameters: presumptive sentencing lanes
Where an offense is subject to sentencing parameters, R.C.M. 1002 tells the judge what to do in plain terms: the military judge shall sentence the accused within the applicable parameters unless the judge finds specific facts that warrant a sentence outside them. The parameters function as presumptive lanes — not absolute floors or ceilings, but boundaries a judge may cross only for stated reasons.
For the accused, the practical meaning is that the likely sentencing range is knowable before trial with far more precision than the old zero-to-maximum spread allowed. That reshapes everything upstream: the calculus on accepting an Article 15 versus demanding trial, the value of a negotiated cap, and the framing of the extenuation and mitigation case presented at the sentencing hearing itself — which now must speak to the specific facts that could move a judge off the presumptive lane.
Criteria: what the judge must consider
Criteria work differently. Where an offense is subject to sentencing criteria, the military judge shall consider them in determining the sentence. R.C.M. 1002. Criteria do not fix a range; they discipline the reasoning — a mandatory checklist of considerations rather than a lane. An offense can be subject to criteria without parameters, and where no parameter applies the judge retains the traditional breadth of discretion, bounded by the maximum punishment for the offense and any mandatory minimum.
Departures and the written-statement requirement
The reform’s accountability mechanism is paper. A judge who sentences outside applicable parameters must find specific facts warranting the departure and must produce a written statement of the factual basis justifying it. R.C.M. 1002.
That requirement runs in both directions, and defense counsel should treat it as an opening rather than a threat. A departure below the parameters is argued the same way an upward one is resisted: with specific, record-supported facts — the extenuation evidence, the mitigation case, the credits and service history developed under R.C.M. 1001. And because the justification must be written, it creates a reviewable record for the appellate courts that the old unexplained unitary sentence never did.
What this means if your offense date straddles the reform
Which regime you are sentenced under turns on when the offense allegedly occurred — not when charges were preferred or when trial begins. Offenses before December 27, 2023 carry the old rules, including possible panel sentencing; offenses on or after that date go to the military judge under parameters and criteria. Charge sheets that allege date ranges spanning the line raise real questions about which system applies, and the answer can change your exposure substantially. Have counsel pin this down before you make any forum or plea decision.
Plea agreements under the new regime
Parameters did not displace negotiated sentencing — they frame it. If the military judge accepts a plea agreement with a sentence limitation, the court-martial must sentence the accused in accordance with it. R.C.M. 1002(a)(2). But acceptance is the checkpoint: the judge can refuse a plea agreement that proposes a sentence outside the parameters if the judge determines the sentence is plainly unreasonable — and can do the same where no parameter applies at all.
The negotiation, in other words, now happens in the shadow of the presumptive lanes. A proposed cap far below the parameters invites judicial scrutiny; a government demand far above them is equally assailable. What terms an agreement may lawfully contain is its own body of law, covered in permissible and prohibited plea agreement terms — including the rule that a term cannot deprive the accused of a complete sentencing proceeding.
Segmented sentences: Flores and Article 56(c)(2)
Congress paired judge-alone sentencing with the end of the unitary sentence. In the FY 2017 NDAA it amended Article 56 and added Article 56(c)(2), UCMJ, eliminating unitary sentencing where a military judge sentences an accused to confinement or a fine for more than one offense: the judge must now specify the term of confinement or fine for each offense. United States v. Flores, 84 M.J. 277 (C.A.A.F. 2024). For multiple terms of confinement, the judge must also determine whether they run consecutively or concurrently. R.C.M. 1002(d)(2)(B).
Segmentation has consequences beyond bookkeeping. It exposes exactly how much confinement each conviction earned — which matters when convictions fall on appeal, and which the courts have already used to confine sentence credits to the specific segment they belong to, as CAAF did with Pierce credit in 2025. How segmentation interacts with Allen, Mason, and Pierce credit is treated in the confinement-credit deep dive. Panels, by contrast, still issue one unitary sentence covering everything.
Mandatory minimums and maximums still apply
The parameters operate inside the older architecture, not in place of it. Where a mandatory minimum is prescribed, the sentence must include it — and since the 2014 NDAA that includes a mandatory dishonorable discharge or dismissal for rape, sexual assault, rape or sexual assault of a child, forcible sodomy, and attempts. Article 56, UCMJ. For premeditated murder and felony murder under Article 118(1) and (4), a plea agreement providing for a term less than life with parole eligibility is prohibited. At the other end, no sentence may exceed the lesser of the offense’s maximum under Part IV of the Manual and the jurisdictional ceiling of the forum — a special court-martial’s limits are far below a general’s. The full ceiling rules, including the habitual-offender escalators of R.C.M. 1003(d), are mapped in maximum punishments under the UCMJ.
The permissible-punishments menu of R.C.M. 1003 likewise survives untouched: reprimand, forfeitures, fine, reduction, restriction, hard labor without confinement, confinement, punitive separation, and death for a narrow set of offenses. Each element keeps its own technical rules, which segmentation does not displace — forfeitures at a special court-martial remain capped at two-thirds pay with no allowances, restriction cannot exceed two months, and the reprimand illustrates how precisely the roles are divided:
“A court-martial shall not specify the terms or wording of a reprimand. A reprimand, if approved, shall be issued, in writing, by the convening authority.”R.C.M. 1003(b)(1)
In other words, the judge decides whether a punishment is adjudged; other actors and other rules still control how several punishments take effect — a punitive discharge, most consequentially, is not executed until appellate review is complete.
Practitioner’s note
We prepare every post-reform sentencing case as a departure case, in both directions. That means building the record of specific facts a judge would need to go below the parameters — documented rehabilitation, extraordinary service history, credits, family and treatment evidence — and simultaneously walling off the specific facts the government would need to go above them. The written-statement requirement rewards precision: judges depart on facts, not themes. In plea negotiations we also model the proposed cap against the applicable parameters before signing, because a cap a judge is likely to call plainly unreasonable is not a deal — it is a delay.
Frequently asked questions
What are military sentencing parameters?
Presumptive sentencing lanes attached to particular offenses. Where parameters apply, the military judge must sentence within them unless the judge finds specific facts warranting a sentence outside them — and any departure requires a written statement of its factual basis. They structure the judge's discretion the way the old zero-to-maximum system never did.
Does a panel still decide my sentence at a court-martial?
Not for new offenses. For non-capital offenses committed on or after December 27, 2023, the military judge sentences the accused even when members decided findings. Panels still sentence capital cases and cases involving older offenses, where any sentence other than death requires three-fourths concurrence.
Can a military judge sentence outside the parameters?
Yes, in either direction — but only on specific facts warranting the departure, and the judge must justify it in a written statement of the factual basis. That makes the sentencing record, developed through the R.C.M. 1001 hearing, the raw material for both seeking a downward departure and resisting an upward one.
Do sentencing parameters override my plea agreement?
No. If the judge accepts a plea agreement with a sentence limitation, the court must sentence within it. The check comes at acceptance: a judge may refuse an agreement proposing a sentence outside the parameters — or any sentence where no parameter applies — upon determining the proposed sentence is plainly unreasonable.
What is a segmented sentence in the military?
When a military judge sentences an accused for multiple offenses, the judge must specify the confinement term or fine for each offense separately and state whether confinement terms run consecutively or concurrently, rather than announcing one lump sentence. Panels, where they still sentence, continue to issue a single unitary sentence.
