Yes, evidence of a prior debarment from federal service or contracting can be admissible as character evidence during the sentencing phase of a court-martial, but it is generally inadmissible during the findings (guilt or innocence) phase. During the findings phase, such evidence would be considered improper “propensity” evidence under Military Rule of Evidence 404, as it would be used to argue that because the person was debarred for some past issue, they are more likely to be guilty of the current charged offense. A defense attorney would successfully move to exclude it.
However, after a conviction, the rules for sentencing are much broader. Under Rule for Courts-Martial (RCM) 1001, the prosecution can introduce evidence of the accused’s past conduct and character to argue for a harsher sentence. A debarment is an official administrative action that reflects negatively on a person’s judgment, reliability, and trustworthiness. The prosecutor could introduce the debarment record as evidence to show that the accused has a history of failing to meet federal standards of conduct.
The defense attorney would work to mitigate the impact of this evidence. They would put the debarment in context, explaining the specific reasons for it and arguing that it was for a minor or unrelated issue. They would present evidence of the accused’s good performance and character since the debarment to show that they have been rehabilitated. The goal is to convince the panel that the old debarment is not relevant to determining a fair sentence for the current military offense.
