If the judge Orders the Long form and all companion documents from Hussein, that exist in the Hawaiian state files, and Hussein fails to comply, then the Plaintiff wins by Default.
Then it goes to the next appeals court that will probably want to help Hussein. But the peril is, it gets bigger legs.
The plaintiff would not win by default, but the effect would be the same. It would be more akin to a summary judgment based on discovery violations.
If that were to happen, Obama would have forfeited his opportunity to prove his right to the office of President and would not be allowed to offer evidence of his eligibility in an appeal. Whatever evidence he wants to present must be presented to the trial court.
