The U.S. Supreme Court has refused to take up an appeal of a California attorney who has lost lower-court challenges to Barack Obama’s presidency based on a claim he wasn’t born in the United States.

The case originated with Rancho Santa Margarita-based attorney Orly Taitz and Ramona, Calif.-based lawyer Gary G. Kreep.

Taitz, who represented military officers who questioned whether they should follow the commander in chief’s orders, left the case after U.S. District Court Judge David O. Carter threw the lawsuit out and an appellate court rejected it.

Kreep–who represents the Rev. Wiley Drake, an Orange County clergyman and the vice presidential nominee of the American Independent Party in 2008, and Markham Robinson, the chairman of the American Independent Party–kept the appeal going up to the nation’s high court.

Kreep said he has “two more cases in the pipeline,” based on arguments that the major political parties do not do anything to properly determine whether a candidate is legally eligible for the White House.

“They have no incentive to do so. They just want someone to win,” Kreep said.

Although the president last year released his long-form birth certificate to convince his doubters, Kreep continues to think it’s not a legitimate document.

Officials in Hawaii, including Democratic and Republican governors, have said the birth certificate is legitimate. There were also a birth announcement at the time in the local newspaper.

The Annenberg Public Policy Institute and CNN have also conducted investigations that determined the birth documents are legitimate.

Carter ruled in 2009 that a court was not the proper place to challenge a president’s election, which echoed a similar ruling from a federal judge in Georgia. The judge in Georgia fined Taitz $20,000 for “frivolous” litigation.
