This is something that I have pondered myself. My understanding is that Hawaiian law requires a notation if a birth certificate has been amended. At the moment, i'm operating on the assumption that this only applies to amendments requested by the parent or guardian, but do not hold in the case of amendment by adoption or otherwise ordered by a judge. Were birth certificates which were amended by adoption to require a notation that they have been amended by adoption, it would defeat the purpose of preventing the child from knowing they are adopted.
I've recently looked at Hawaiian adoption laws, and they have a quite extensive body of language regarding secrecy and privacy for adopted children.
Of course, at this point, I am willing to consider all sorts of peculiarities from the state of Hawaii, up to and including accidentally or purposefully violating their own laws. Hawaiian law says they will provide a birth certificate to any election official that requests it for the purposes of an election.
Yeah, I just bet they will. Even assuming they did, would it be the Original, or the Adoption amended version?
Well, since we have yet to see an authentic Barry LFBC or COLB, your guess is as good as mine.
