An appeal of non-judicial punishment shall be submitted within how many working days of the imposition of NJP, or the right to appeal shall be waived in the absence of good cause shown?

The correct answer is five working days. According to the Uniform Code of Military Justice (UCMJ) regulations, an individual who receives non-judicial punishment (NJP) has a specific timeframe to submit an appeal; this timeframe is set to ensure that appeals are addressed in a timely manner. If the appeal is not submitted within five working days from the date the NJP is imposed, the individual forfeits the right to appeal unless good cause is demonstrated. This structure is in place to promote prompt resolution of disputes, maintain discipline, and ensure that the processes surrounding NJP are handled efficiently.
