No, Congress has to count the legal votes.
If Obama / Biden are disqualified, it goes to the first runner-up.
20th Ammendment applies.
Biden becomes acting POTUS until a real POTUS can be chosen.
I believe that Pelosi would be in legal trouble herself, seeing that she would have broken Hawaiian state laws by certifying that Obama.
As Robert Byrd has severe health problems and may be deemed unfit to serve, that would put Hillary Clinton a heartbeat away from the acting-Presidency.
Some time ago, someone offered a plausible summary using on e of the clauses in the Constitution (don’t rightly recall the cite).
Obama will have been found not qualified to hold the office. Biden will assume the presidency (and appoint a VP?, not sure) until such time that a qualified person can be elected.
Up-shot: New elections with Biden as temporary POTUS. YMMV
The difficult thing will be when we get to all the things that he did as POTUS-poseur.
