Timothy Sandefur tentatively says no. I tend to agree; however, Roslin’s decision to send Lt. Thrace (Starbuck) back to Caprica on a secret mission at the very least violated the military chain of command.

The proper response, however, is not a coup. In the grand scheme of things, Roslin’s action did not lead to the sort of imminent danger that would justify bypassing civilian procedures; presumably, the Quorum of Twelve can impeach and/or remove the president, or there is a civil judiciary that can exercise that authority.

The larger political mess is that Adama’s incapacitation has left Colonel Tigh holding the bag for this decision, and he neither has the wherewithal or the gravitas to resolve things the way Adama might have been able to do.
