Would that be argued as being "double jeopardy" or would civilian court be the first trial and not "double jeopardy" because this trial was a military trial?
Somethin' like that...
In the words of the next pre-annointed, suit-panted, POTUS:
"What difference at this point does it make ?"
So far as I know double jeopardy comes into play when you are found not guilty. In that situation the prosecuter cannot go back to the drawing board to put a better case together and retry you. Someone found guilty can always appeal the verdict and hope to eventually be found not guilty.
There are probably some differences between civilian and military trials but there are others here more knowledgeable about that.
