This ruling from 2009 went to the Supreme Court of the United States which denied Cert., so it stands:
Barnett, et. al. v. Obama, et. al., U.S. District Court Judge David O. Carter: “There may very well be a legitimate role for the judiciary to interpret whether the natural born citizen requirement has been satisfied in the case of a presidential candidate who has not already won the election and taken office. However, on the day that President Obama took the presidential oath and was sworn in, he became President of the United States.
Any removal of him from the presidency must be accomplished through the Constitution’s mechanisms for the removal of a President, either through impeachment or the succession process set forth in the Twenty-Fifth Amendment.
Plaintiffs attempt to subvert this grant of power to Congress by convincing the Court that it should disregard the constitutional procedures in place for the removal of a sitting president. The process for removal of a sitting president—removal for any reason—is within the province of Congress, not the courts.”—U.S. District Court for the Central District of California, October 29, 2009

The Courts in the "Birther Litigation" collectively indicated a strong reluctance to disenfranchise 62 million voters by judicial act. That action, if it is to happen, needs to be accomplished through the only other elected federal branch of government.
Though the "one honest judge" mantra keeps the dream alive for some.
