Speaking of California laws and precedent on this very issue (eligibility):
California Judge Ruling in Keyes Lawsuit on Obama Qualificationshttp://www.ballot-access.org/2009/03/13/california-judge-ruling-in-keyes-lawsuit-on-obama-qualifications/
March 13th, 2009
On March 13, California Superior Court Judge Michael Kenney tentatively ruled against Alan Keyes, in the lawsuit concerning whether President Barack Obama meets the constitutional qualifications to be president, and whether the California Secretary of State should have put him on the ballot. The case is Keyes v Bowen, 34-2008-8000096-CU-WM-GDS. The 6-page opinion seems to strengthen the rights of political parties to place anyone they wish on the November ballot, regardless of that candidates qualifications.
The decision says, Defendants contend that Election Code sec. 6901 requires the Secretary of State to place on the ballot the names of the candidates submitted to her by a recognized political party and that she has no discretion to override the partys selection. The Court finds that the First Amended Petition fails to state a cause of action against the Secretary of State Federal law establishes the exclusive means for challenges to the qualifications of the President and Vice President. That procedure is for objections to be presented before the U.S. Congress pursuant to 3 U.S.C. section 15.
In 1968, the California Secretary of State refused to list Eldridge Cleaver on the November ballot as the presidential nominee of the Peace & Freedom Party. Cleaver and PFP sued the Secretary of State, but the State Supreme Court refused to hear the case, by a 6-1 vote. Cleaver and the party then asked the U.S. Supreme Court to intervene, but that Court refused, 393 U.S. 810 (October 7, 1968). In this current Keyes lawsuit, attorneys for the Defendants claimed there was no such lawsuit. The attorney for Keyes did not have the California Supreme Court citation (58 Minutes 411), nor the U.S. Supreme Court cite, so he wasnt able to establish the existence of this 40-year old precedent that does seem to give the Secretary of State the authority to refuse a partys choice for president, if the Secretary of State thinks the party chose someone who doesnt meet the constitutional qualifications. Keyes will appeal and his appeal will include the Cleaver precedent citation.
Eldridge Cleaver had been removed from the California ballot because the Secretary of State had learned that he was only 33 years old.
Looks to me that the ruling was made to kick the case one more step up the ladder to the SCOTUS.
