They haven't gotten that far. Cases have been thrown out on "standing" and "justicibility".
But the "defendant" doesn't have to fight producing it either, it's optional. But he has fought it, and thus my comment about his being reluctant to produce it.
Which of the eligibility lawsuits would have ended if all Obama had done was produce a physical copy of his COLB to the defense?
If none, then what benefit would there have been to produce the COLB, if it wouldn't have ended the lawsuit?
