Naval Base Yokosuka Non-Judicial Punishment Defense Lawyers
Table Contents
Non‑Judicial Punishment, commonly known as Article 15 in the Army and Air Force, NJP in the Navy and Coast Guard, and Captain’s Mast or simply Mast in naval services, is a disciplinary process commanders use to address alleged minor misconduct without resorting to formal judicial proceedings. It is an administrative mechanism authorized under Article 15 of the Uniform Code of Military Justice.
Unlike a court‑martial, which is a criminal trial that may result in federal convictions and judicially imposed sentences, NJP is not a court proceeding and does not involve a judge or jury. The commander acts as the fact‑finder, determines whether misconduct occurred, and imposes limited administrative or disciplinary measures within the scope allowed by regulations.
NJP results in entries within a service member’s personnel records because all actions taken under Article 15 or Mast must be documented for accountability and administrative tracking. These records serve as the official account of the disciplinary action and remain part of the service member’s permanent military file in accordance with service policies on retention and personnel management.
Non‑Judicial Punishment (Article 15, NJP, or Mast) at Naval Base Yokosuka is a formal command action that can seriously affect a service member’s rank, pay, and long‑term career. Gonzalez & Waddington provide guidance on NJP procedures and member rights. For information, call 1‑800‑921‑8607.

If you’re under investigation or facing charges, this video explains what your rights are and how experienced criminal defense lawyers can make the difference.
At Naval Base Yokosuka, Non‑Judicial Punishment is treated as a significant command action because it is applied at the discretion of senior leadership and carries formal visibility across the chain of command. The process involves documented findings and review at multiple levels, which distinguishes it from purely informal or minor corrective measures.
NJP also has a direct impact on a Sailor’s career trajectory, particularly regarding promotion eligibility and competitive assignment opportunities. Recorded NJP outcomes can influence ranking during advancement cycles and can limit access to duty stations or positions requiring heightened trust and responsibility.
Additionally, an NJP event often initiates follow‑on administrative steps such as counseling, monitoring, or suitability reviews. These actions are not punitive in nature but reflect the Navy’s requirement to assess long‑term readiness and performance, which is why NJP is regarded as more consequential than routine, minor discipline.

The Non-Judicial Punishment process at Naval Base Yokosuka follows established military procedures designed to address alleged misconduct within the command structure. Each stage focuses on documenting events, reviewing available information, and carrying out the steps required under Navy regulations.
The sequence below outlines how the process typically unfolds from the initial report through official documentation. These steps reflect the administrative framework used at the installation.
Service members may face administrative discipline when situations arise involving misunderstandings or lapses related to military orders or base regulations. These matters can include issues such as duty‑related expectations, adherence to established procedures, or questions about how specific instructions were interpreted in day‑to‑day operations.
Alcohol‑related incidents are another frequent source of review, particularly when the use of alcohol contributes to behavior that conflicts with command guidance or local policies. Such cases are handled as administrative concerns focused on restoring readiness, maintaining good order, and encouraging sound judgment rather than assigning criminal guilt.
Concerns about conduct or performance, such as interpersonal conflicts, professionalism expectations, or challenges meeting routine standards, may also result in Non‑Judicial Punishment proceedings. These actions are designed to address and correct the underlying issues, support the member’s development, and promote a stable working environment within the command.








Non‑Judicial Punishment proceedings at Naval Base Yokosuka often rely on statements and reports prepared by personnel who observed relevant events or documented official actions. These materials may include written accounts from service members, security personnel, or supervisors that outline timelines, behaviors, or circumstances surrounding the alleged misconduct.
Investigative summaries are also frequently used, providing condensed findings from command‑directed inquiries or military law enforcement reviews. Such summaries typically highlight collected information, describe key points from interviews, and outline physical or digital materials examined during the inquiry.
Witness accounts, including oral or written statements from individuals with direct knowledge of the events, may be incorporated as well. The selection and presentation of these sources fall under command discretion, allowing leadership to determine which materials are relevant and appropriate for consideration during the proceeding.
Non‑Judicial Punishment at Naval Base Yokosuka can result in formal letters of reprimand, which often become part of a service member’s official record and may influence how later decisions about retention or advancement are made.
Commanders may also initiate separation processing after NJP, particularly when the underlying misconduct raises concerns about reliability, conduct, or suitability for continued naval service.
Some cases can be routed to a Board of Inquiry (BOI), where a panel reviews the service member’s record and the circumstances of the misconduct to determine whether separation is warranted and, if so, what characterization of service may be assigned.
These administrative actions can create long‑term career consequences, including diminished promotion opportunities, reduced competitiveness for special programs, and obstacles to reenlistment or future civilian employment.
Non‑Judicial Punishment (NJP) at Naval Base Yokosuka often arises after command-directed investigations uncover alleged misconduct. These investigations supply the commanding officer with the facts needed to decide whether NJP is appropriate or whether the matter should proceed toward more serious administrative or judicial processes.
For some service members, NJP may be accompanied by administrative measures such as Letters of Reprimand, which can have long-term career consequences even when no court-martial occurs. These letters may be issued in lieu of, alongside, or following NJP depending on the commander’s assessment of the misconduct and the member’s service record.
When the alleged conduct indicates deeper concerns about a sailor’s suitability for continued service, actions may escalate beyond NJP to Boards of Inquiry or even to court-martial escalation. These higher-level forums evaluate retention or criminal culpability and represent the more severe end of the military justice spectrum when NJP is deemed insufficient to address the misconduct.

Non‑Judicial Punishment is an administrative disciplinary action, not a criminal court process. It does not create a civilian criminal conviction, though it is still an official military proceeding.
NJP is handled by a commanding officer and is designed for addressing certain minor misconduct. A court‑martial is a formal judicial process with more extensive procedures and potential penalties.
NJP can include administrative penalties that involve reductions in rank or temporary effects on pay. The specific actions depend on the command authority and the circumstances of the case.
An NJP entry can be reviewed by promotion boards as part of a service member’s record. Its presence may be one of several factors considered during evaluation.
An NJP itself does not automatically require separation, but it can be referenced in later administrative reviews. Commands may consider it as one part of an overall performance or conduct evaluation.
The retention of NJP documentation depends on the type of record in which it is filed. Some entries may remain available for review during a member’s career, depending on service regulations.
Service members may choose to consult a civilian attorney for general information or discussion. Civilian lawyers do not participate in the NJP hearing itself but can provide outside support.

Yes, NJP is often considered during security clearance reviews and may be treated as adverse information. This can result in suspension or revocation of a clearance.
