I have a really good answer for you. It just now occurred to me that Obama, by releasing what he claims to be his birth certificate, has made that document public knowledge and has by default consented to the release of that information. In other words he no longer has an expectation of privacy concerning that document. SO, a subpoena can reach that document because there is no privilege left for him to exercise to prevent it. Hawaii has no privilege or privacy rights only Obama does. Now that he has “released it” the State shouldn’t have grounds to quash.
I think they could still legally refuse to present the document with the criteria demanded. Legally, mind you.
But politically, people better start questioning - if the “released” BC is legit, why not produce the typewritten one?
