A service member sometimes faces parallel tracks: an administrative proceeding such as a separation board or a board of inquiry on one side, and a court-martial on the other. A natural worry is whether declining to testify in the administrative forum can later be used against the member when a court-martial decides on a sentence. The protections against self-incrimination in the military are strong, and a proper exercise of the right to remain silent should not become a basis to increase punishment at a court-martial. The analysis, however, depends on understanding both the right itself and the distinct rules that govern sentencing.
The right to remain silent in the military
A service member’s protection against compelled self-incrimination is broad. It rests on the Fifth Amendment to the Constitution and on Article 31 of the Uniform Code of Military Justice, which provides protections that in some respects exceed those in the civilian system. A member generally cannot be compelled to make statements that could be used against the member in a criminal proceeding. This protection reaches across forums, which is why declining to testify at an administrative board does not, in itself, amount to misconduct. Exercising a recognized right is not wrongdoing, and it is not the kind of conduct that properly aggravates a sentence.
Silence at sentencing cannot be held against the accused
At a court-martial, the accused has several choices when it comes to sentencing. The accused may testify under oath, may make an unsworn statement, may do both, or may remain silent. When the accused chooses to remain silent, the finder of fact is not to draw any adverse inference from that silence. This rule reflects the constitutional principle that the exercise of the right against self-incrimination cannot be turned into evidence of guilt or used to justify a harsher punishment. The same logic disfavors treating a prior, lawful refusal to testify in another proceeding as an aggravating factor at sentencing.
What sentencing evidence is actually allowed
Sentencing at a court-martial is governed by specific rules about what each side may present. The government may offer evidence in aggravation that is directly related to or resulting from the offenses of which the accused has been found guilty, along with certain personal-data and prior-record matters the rules permit. The defense may present matters in extenuation and mitigation. The key point is that aggravation evidence must connect to the offense …
