Then a civil suit would be coming down the pike against Obama for wrongful dismissal or termination.
Oh,please...what civilian court would touch that with a ten foot pole?
Which would immediately be tossed due to the ever popular lack of standing. In order to establish standing Lakin would have to show a causal relationship between the injury he suffered and an action on the part of Obama. Since the order to deploy came well below even the Secretary of Defense level it'll be impossible for him to claim that it was Obama's action that caused his court martial.
As I understand it, he can't be separated without a Court Martial. The President can order it, and the officer can accept that. But the officer is still entitled to a Court Martial if he wants one. I'm sure he does in this case.
