How to Appeal Nonjudicial Punishment (Captain’s Mast) in the Navy | Sailor’s Defense Guide
Gonzalez & Waddington, Attorneys at Law defend Sailors worldwide in Nonjudicial Punishment (NJP) hearings, appeals, Boards of Inquiry (BOI), separation boards, and courts-martial. If you received NJP under UCMJ Article 15, you may have the right to appeal. A successful appeal can protect your rank, pay, career, and benefits.
This guide explains how to appeal NJP in the Navy, common mistakes to avoid, and why a strong appeal is vital for your long-term defense strategy.

Why Appealing NJP Matters in the Navy
- FITREP/CHIEFEVAL impact: NJPs are often reflected in evaluations, affecting promotions and billets.
- Separation risk: NJPs are frequently used as evidence at administrative separation boards or BOIs.
- Security clearance: NJPs can trigger review or loss of your clearance.
- Retirement jeopardy: Multiple NJPs can push Sailors out before retirement eligibility.
How the Navy NJP Appeal Process Works
1. Deadline
You generally have 5 calendar days to submit an appeal after NJP punishment is imposed. Extensions are rare, so act quickly.
2. Appeal Authority
The appeal is reviewed by the next higher authority in your chain of command.
3. Grounds for Appeal
You must show that the NJP was unjust (you did not commit the misconduct) or that the punishment was disproportionate.
How to Build a Strong Navy NJP Appeal
1. Collect Evidence
- FITREPs/CHIEFEVALs: Demonstrate a history of strong performance and leadership.
- Witness statements: Especially from those who directly observed events or can confirm your character.
- Official records: Duty logs, watch bills, or message traffic supporting your defense.
- Rehabilitation evidence: Completion of counseling, treatment, or professional development.
2. Identify Weaknesses
Highlight unreliable witnesses, contradictory statements, or lack of corroboration in the command’s case.
3. Use a Professional Tone
Your appeal must be respectful, fact-based, and formatted clearly. Emotional or disrespectful appeals are often ignored.
4. Think Strategically
Your appeal is not just about overturning NJP. It also builds a record that may be critical at a BOI or separation board.
Common Mistakes in Navy NJP Appeals
- 🔥 Submitting a generic “I disagree” appeal with no supporting documents.
- 🔥 Waiting too long and missing the 5-day deadline.
- 🔥 Writing emotional appeals instead of fact-driven ones.
- 🔥 Admitting guilt to seek leniency — which can backfire later at a BOI.
- 🔥 Failing to connect the appeal to long-term defense at separation boards.
