"I'm hopeful that eventually, when we get to a court that can take a good neutral look at this case, that we'll see Hannah vindicated," Orr said.
On the most recent decision in Hannah's case, Orr added, "This case had become so politicized and, as you know, our judges are elected in Texas and it would have been tough for them to overturn this case and face their electorate."
Still, Hannah Overton says she doesn't regret trying to adopt Andrew.
"I wouldn't take that away," she said. "He had brothers and sisters and a mommy and daddy, what he called his forever family, because we had to go through a lot of pain since then. It's not fair to him. Or to us."
