An Article 15 in the USMC is nonjudicial punishment — what Marines call Office Hours or Mast — that lets a commanding officer discipline you for minor misconduct without sending the case to a court-martial.1Navy Judge Advocate General’s Corps. Nonjudicial Punishment It is not a criminal trial and it does not produce a criminal conviction, but the punishments are real: lost pay, restriction, extra duty, and, for most Marines, a possible reduction in rank. The paperwork can follow you through promotion boards, reenlistment, and clearance reviews for years.
What Happens at Office Hours
The process begins when a commanding officer or officer in charge decides your alleged misconduct warrants formal discipline but not a court-martial.2Joint Service Committee on Military Justice. Manual for Courts-Martial – Nonjudicial Punishment You get written notice of the charge and time to review the evidence, talk to a defense attorney, and decide whether to accept or refuse NJP.
If you accept, a hearing is set. The commander runs it. There is no jury, no military judge, and no formal rules of evidence. The command presents its case, you respond, and the commander decides whether the offense occurred. If personally satisfied of guilt, the commander announces a finding and imposes punishment on the spot.
Two levels of NJP exist, defined by who is holding the hearing. Company Grade NJP is conducted by an officer at O-3 (Captain) or below. Field Grade NJP is conducted by an officer at O-4 (Major) or above. The distinction controls how heavy the maximum punishment can be.
Your Right to Refuse and Demand a Court-Martial
The single most important right at NJP is the right to say no. Before punishment is imposed, most Marines can refuse NJP and demand trial by court-martial instead. The exception matters: Marines attached to or embarked in a vessel cannot refuse. This “vessel exception” has long been the most controversial part of Article 15 in the sea services.3Office of the Law Revision Counsel. 10 USC 815 – Art. 15. Commanding Officers Non-Judicial Punishment
Refusing is a gamble. Your commander can no longer impose Article 15 punishment, but the case does not vanish. The command can refer charges to a court-martial, pursue administrative separation, take other administrative action, or drop the matter. For minor offenses, commands often decide a court-martial is not worth the time and expense, and the case ends up handled through lesser means or dismissed. If it does go to court-martial, you face a possible federal conviction and penalties well beyond what NJP could ever reach. A defense attorney can help you weigh those odds against the strength of the evidence and the likely NJP outcome.
Other Rights Before and During the Hearing
Before deciding whether to accept or refuse, you have the right to consult a military defense attorney, typically a Judge Advocate. Use it. An experienced JAG can read the evidence, tell you what punishments are realistic, and help you decide whether to demand a court-martial.
Article 31 protections against self-incrimination apply throughout the process. A commander cannot compel you to make incriminating statements, and questioning of a suspect must be preceded by a rights advisory.4United States Marine Corps Staff Judge Advocate. Practice Advisory – Article 31 Rights Advisories At the hearing, you can stay silent, and your silence cannot be held against you.
If you accept NJP, you can examine the evidence the command is relying on, present your own evidence, call witnesses whose testimony is reasonably available, and make a personal statement addressing the facts, offering mitigating circumstances, or explaining context. The hearing is informal, but you do get a meaningful chance to be heard.
Maximum Punishments a Commander Can Impose
Article 15 sets strict caps that depend on the rank of the officer holding the hearing and, in some cases, the rank of the Marine.5Office of the Law Revision Counsel. 10 USC 815 – Art. 15. Commanding Officers Non-Judicial Punishment These are ceilings. Commanders regularly impose less.
Company Grade NJP (O-3 and Below)
For enlisted Marines, the maximums are:
- Forfeiture of up to 7 days’ pay.
- Extra duties for up to 14 consecutive days.
- Restriction for up to 14 consecutive days.
- Reduction of one pay grade, only if that grade falls within the officer’s promotion authority.
- Correctional custody for up to 7 days (E-3 and below only in the Marine Corps).6United States Marine Corps. NJP Punishment Chart
Field Grade NJP (O-4 and Above)
The ceiling rises considerably:
- Forfeiture of up to half of one month’s pay for two months.
- Extra duties for up to 45 consecutive days.
- Restriction for up to 60 consecutive days.
- Reduction to the lowest or any intermediate pay grade within the officer’s promotion authority. Marines above E-4 cannot be reduced more than two pay grades.
- Correctional custody for up to 30 days (E-3 and below only in the Marine Corps).6United States Marine Corps. NJP Punishment Chart
A USMC-specific rule catches many senior Marines off guard: NCOs at E-6 (Staff Sergeant) and above cannot be reduced in grade through NJP at all.6United States Marine Corps. NJP Punishment Chart A Staff Sergeant or Gunnery Sergeant who receives NJP can lose pay and be restricted, but the rank stays intact unless the case goes to court-martial.
Suspended Punishment
Commanders do not always impose the full punishment immediately. The imposing officer, or a successor in command, can suspend any part of the punishment on a probationary basis for up to six months.3Office of the Law Revision Counsel. 10 USC 815 – Art. 15. Commanding Officers Non-Judicial Punishment Stay out of trouble during that period and the suspended portion is usually remitted and never takes effect. New misconduct, and the commander can lift the suspension and impose the original punishment. There is no separate hearing or appeal for the decision to vacate a suspension. A strong mitigation case at the hearing — your record, personal circumstances, the nature of the offense — is often what persuades a commander to suspend rather than execute.
How to Appeal
If you believe the punishment was unjust or unsupported, you can appeal. The appeal must be submitted within five calendar days of the hearing. Three grounds are recognized:
- Insufficient evidence to support the finding of guilt.
- Excessive punishment relative to the offense.
- Procedural error in how the NJP was conducted.
The appeal goes to the next superior authority in the chain of command. That reviewing officer can set aside the finding, reduce the punishment, or deny the appeal. Filing does not pause execution: if you were assigned extra duties, those typically start running while the appeal is pending. Separately, the commander who originally imposed punishment, or a successor in command, can set aside the NJP in whole or in part at any time if it resulted in a clear injustice.7MyNavyHR. Setting Aside Nonjudicial Punishment (NJP)
What an NJP Does to Your Career
The daily punishment ends when the days run out. The administrative fallout is where NJP does its real damage.
An NJP creates an entry in your service record that promotion boards and reenlistment authorities see. A Marine competing for promotion with a recent NJP on record sits at a serious disadvantage even when the underlying offense was minor. Coming up on the end of an enlistment, an NJP can trigger a reenlistment bar or lock you out of certain bonus programs. A reduction in grade drops your base pay immediately and keeps dropping it every month afterward.
Security clearances are another pressure point. Clearance adjudicators review your full record, and an NJP involving dishonesty, substance abuse, or financial misconduct can raise flags during a background investigation. It will not automatically disqualify you, but it will get a close look.
One boundary worth knowing: NJP is not a criminal conviction. Unlike a special or general court-martial, NJP and summary courts-martial do not normally appear on your civilian criminal record.8United States Marine Corps Defense Services Organization. NJP Rights and Punishment Guide After you leave the military, an NJP will not surface on a standard background check the way a conviction would. It remains part of your military personnel file, though, and a future employer requesting military records or seeing your characterization of service and reenlistment code may pick up on it indirectly.
NJP entries generally stay in the official military personnel file for two years, though the exact handling depends on the command and the offense. If you have exhausted your appeal and still believe the NJP was unjust, you can petition the Board for Correction of Naval Records to have the entry removed. That process requires strong evidence and can take months.
