Legal Question in Appeals and Writs in Virginia

Re: Courts Martial- expungement of record/Federal

Whether or not your case was "expunged" won't matter to the clearance-adjudicating authorities. Moreover, you might be permanently ineligible for a clearance under the Smith Act which provides that a clearance may not be granted to anyone who has been "discharged or dismissed from the Armed Forces under dishonorable conditions." Note that the law doesn't say, "dishonorable discharge," just "dishonorable conditions," whatever that means. The Smith Act would also apply if you were ever sentenced to more than one year imprisonment, regardless of the actual time served. Almost certainly you would be ineligible for an interim clearance, whether or not you would be granted a clearance after a full adjudication is anybody's guess -- but I would not get my hopes up (unless you are close personal buds with a flag officer or Cabinet secretary in charge of your workplace).
