It is my understanding that our judicial systems must assume that all laws are constitutional until challenged by someone with standing. Otherwise every law passed would have to pass through the judicial system before becoming accepted law.
No. The courts are silent on the question of a law's constitutionality until an appellate court has agreed to adjudicate a case brought by a party with standing to bring suit.
I almost considered this point before posting my post, above. Yes, I guess Holder is a little smarter than I gave him credit for. He's right, they are presumtively Constitutional.
HOWEVER, that's not the point.
