Apuzzo refutes your contention that a self-authenticating documents is unassailable. Self-authentication is a presumption that can be rebutted, if I understand the FRE correctly.
Your lawyerly assertion that Apuzzo’s argument “has yet to score him a single victory" is correct, but only because there has never been a ruling on his argument.
Apuzzo has never had a chance to impeach Obama’s alleged Factcheck COLB in any court case with his argument and evidence because that COLB has never been entered into evidence by Obama or the DOJ.
It appears only the quo warranto suggested by Judge Carter in the correct venue would give the opportunity for Apuzzo or Donofrio to challenge the self-authentication of any HI COLB placed into evidence.
