They have ruled that while the civilian courts are open and operating, habeas corpus may not be suspended.

True, in Ex Parte Milligan. However there was no precedent in place when Lincoln was forced to suspend habeas corpus and the government operated as they believe the law required. To the best of my knowledge the federal government abided by the Ex Parte Milligan ruling after it was made.

Hummmm, when I use the "no standing legal authority" argument, against the claim that the secession of the Southern States was illegal, I am told that it doesn't hold water.
