Which of the following is NOT a step in the Non-Judicial Punishment (NJP) process?

The correct answer identifies the Judicial Review Board as not being a step in the Non-Judicial Punishment (NJP) process. In the context of NJP, the procedure typically involves a series of specific steps aimed at addressing disciplinary issues at a level that avoids formal court procedures.

Investigation by the master at arms is part of the NJP process, as it is crucial to gather relevant facts and evidence before addressing any potential misconduct. This investigation helps determine whether there are grounds for disciplinary action.

Referral of charges is also an essential step, as it involves formally notifying the accused of the charges against them and initiating the NJP process.

An XO Inquiry may occur when the executive officer assesses the circumstances surrounding the conduct in question, further aiding in understanding the situation before moving forward with the NJP.

In contrast, a Judicial Review Board is not part of the NJP process; rather, it pertains to court-martial procedures, where a higher level of review and legal scrutiny is applied. Thus, identifying this as the incorrect option demonstrates an understanding of the distinct processes involved in military justice.
