Personhood. It's not for chimps.

"Needless to say, unlike human beings, chimpanzees cannot bear any legal duties, submit to societal responsibilities or be held legally accountable for their actions," the judges wrote in their decision. "In our view, it is this incapability to bear any legal responsibilities and societal duties that renders it inappropriate to confer upon chimpanzees the legal rights — such as the fundamental right to liberty protected by the writ of habeas corpus — that have been afforded to human beings."

So ruled a New York Appeals Court today. But doesn't that also apply to three years old humans? And do they not have a right to liberty and constitutional protection?
