Maybe it was more like the others aboard think Marina is Setsuna's responsibility as he rescued her outside of the original plan. Thus he calls the shots as to what to do about her, that is, how to get rid of her. With the original plan or at least the original structure of the CB somewhat lost I think all the pilots are now basically the bosses, and so Setsuna's order could be considered the common policy (to remove Marina from the ship).
