I just cannot imagine the judiciary exposing itself to all of the crazy claims that will result from a willingness to become a screening committee for presidential candidates. They have read all of the background that everyone has now read. They know that there is no clear answer and that there is no way to avoid looking like the court is just making up standards on a case by case basis. And, they know that they will never satisfy the true believers because the court will no doubt be utilizing fraudulent documents from government agencies, stuff like birth certificates, etc. ;-)
There have been quite a few judicial rulings that found Obama to be a natural born citizen. I can envision circumstances where courts could rule someone to not qualify as a natural born citizen which could set the stage for a state Secretary of State ruling that a candidate does not qualify for the ballot or a ruling could provide the grounds for the impeachment of an already elected official.
