Except they were not “qualifying documents” in the sense that no candidate had to submit a BC to get on the ballot.
If push come to shove, the Arizona SoS will request a BC from the Hawaii SoS. Hawaii will send a certified copy of the COLB and that will be that.
Arizona is not going to accuse Hawaii of forging Obama’s BC.
They don't need to. If they are smart, they should accuse Hawaii of sending them a copy of the record for a replacement birth certificate which was legally issued to an adopted child.
It isn't a "forgery", (Legally created replacement birth certificates are not "forgeries.") but it isn't an original record either. (Though it is designed to resemble one.)
There is a reason Hawaii didn't certify it as a "True and Correct copy of the original record..." The way they used to certify birth certificates.
