Perhaps you can answer my question:
Is presenting a photocopy or scan of a physical notarized paper legal document in a court of law a legally valid procedure or not?
But! Where do you think you are going with this?
The public releases of the COLB and the LFBC are intended to be informational, not a basis of legal proof in the strictest sense.
If you want to argue that the US needs a better legal foundation for verifying NBC status of Presidential candidates, I'm right there with you.
No President has ever (at least to my knowledge) sought for or receive any formal court approval of their NBC status, just to phrase it that way.
Only a small handful of our Presidents even have or had what we recognize as modern ‘Birth Certificates’.
It might be if the original were destroyed and there was no recourse to an issuing agency. That's a big and
there. Looming over any attempt to pull a BC fraud of this magnitude is the continuing availability of the Hawaii Department of Health to vouch for the facts or not. That's why arguing about seals and pixel sizes and document layers is such a waste of time.
