If he had produced his COLB to a court, the plaintiffs would have demanded the original vault birth certificate. If he had produced that, they would have demanded that document examiners examine it. After both sides' examiners made their reports, there would have had to be a trial to decide if it was legitimate. If the court found the certificate legitimate, the plaintiffs would have demanded evidence about his adoption in Indonesia, about whether he ever travelled on a foreign passport, if he had registered in college as a foreign student, and on and on. If Obama had conceded for one minute that any court had any role in this process, he would have been tied up in litigation for 8 years. It looks like it's Obama's plan as a minimum is to contend on every point on his citizen issue anyway for as long as he can. Obama wouldn't show that COLB in court since it's a clear forgery. Even the state of Hawaii does not take it's issued COLB's as proof in certain cases as ID because they have minimum information. And the court would not compel Obama to produce any documentary evidence that Hawaii issued, it would subpoena the state. The only plausible reason Obama is contesting this is because he believes he's not eliglble to be president.
"Obama wouldn't show that COLB in court since it's a clear forgery. Even the state of Hawaii does not take it's issued COLB's as proof in certain cases as ID because they have minimum information." Not sure why you say it's a "clear forgery". Even if it is, it's not that obvious.
The bit about Hawaii not taking them is not true.
