There were actions questioning Obama’s eligibility before the election. Berg tried to point out the issues and the constitutional crisis if someone who was ineligible was actually elected.
Donofrio and others tried to get SCOTUS to review the issue before the inauguration.
But there is Quo Warrento writs to file for someone who is in office and is ineligible.
But it is not clear that a civil case can not be brought by candidates for the President that the winner was not eligible to run. That can not throw him out. But can serve to force discovery that upon getting proof would be brought in a Quo Warrento action.
If it is proven that Obama is ineligible by not being a Natural Born Citizen then he is not a legitimate President and can be removed.
But I certainly applaud all actions to make it very clear that proof of being a Natural born citizen is required for anyone to run for President or Vice President in the future.
You are missing my point. Under the election laws of most states, these types of challenges must be made at the time the candidates name is placed on the ballot. For example, IIRC in my state, legal action to contest a candidate's qualifications must be made within ten days after the name is placed on the ballot, and the challenge must come from a person who has a real and personal stake in the outcome of the dispute that is distinct from the interests of the general public. The time to contest the candidate's qualifications is very short because elections are expensive, and therefore, these types of disputes need to be resolved long before the ballots are printed and votes are cast.

The time to go to court is at the time when the candidates name is placed upon the ballot in the particular state, not after the election is held and the people have spoken.

This particular writ has been oversimplified by people who have no clue as to their modern existence and purpose. In many states, including mine, the writ has been abolished, and the proper procedure is not to challenge the candidate directly, but to challenge the election commmissioner's decision to allow the unqualified candidate's name to appear on the ballot.
