Every so often the comes up of impeachment by prior conviction under Mil. R. Evid. 609. The reminder is that:
The fact of a pending appeal does not defeat admission, but it may be brought up and discussed. Mil. R. Evid. 609(e).
A summary court-martial may not be used to impeach under this rule. There may be other ways to impeach with conduct subject to discipline at a summary court-martial, but not Mil. R. Evid. 609. (Further evidence that an SCM is not considered a “conviction?”)
