Bill of Attainder and Schiavo
My quick bit of "legal research" suggests that the definition normally includes "punishment without trial," so that it's not just about naming a specific person, but about doing so for a nefarious purpose.
Even so, the notion of the whole Congress being called in to adjudicate a family tragedy like this really does step way over any line of the legitimate powers of the state, whatever the real meaning of a Bill of Attainder is.
