The evidence is there to establish a challenge to the Full, Faith And Credit Clause.
What evidence effectively refutes the prima facie evidence of a state certified birth certificate? That is one large hurdle! And, like a said, allegations and speculation don’t count. You need credible records and witnesses.
Think of it like this: You put a candy bar in your bedroom at 1:00. When you got back at 1:30, you discover the candy bar is gone. You go to your mother and tell her than your brother Timmy ate your candy bar. Your mother says, Nonsense, your father tells me that Timmy has been with him from 11:00 until now. He couldn’t have eaten your candy bar. Well, the state record is like your father’s word. It is authoritative and credible. Your mother WILL believe your father. One state, as mandated by the Full Faith and Credit Clause, WILL believe another state. Think about what you would have to do to get your mother to believe something other than what your father says. High hurdle, right? Pointing out that your brother is a known liar and thief isn’t credible proof. You need to prove that the information your father has is incorrect. The same applies when challenging state records. State records are presumed correct. That’s part of the Full Faith and Credit Clause.
