Just don’t have enough info on this matter: who’s suing and why. Apparently, it’s an administrative agency, so may be (probably is) connected with some individuals challenging O’s being on the GA ballot.
But, I don’t think GA adopted a law requiring birth certificates, so don’t know what their ‘standing’ would be or what law would require one be produced, much less from another state. Maybe more info will be forthcoming that would make it understandable.
I checked on the requirement here in Virginia and, IIRC, all we require is an affidavit saying the candidate is eligible!
