You're wrong. They intentionally drafted it so that it would be declared unconstitutional. Actually, the conservatives wanted to pass one that was constitutional, and the liberals refused. So they modified it so that the liberals would go along, but the price of going along was that they had to write it in such a way that it was 100% certain to be declared unconstitutional. Basically, they wrote it so that it applied only to one person, namely Terri Schiavo. They could have, should have, written it so that it applied to everyone, and it would have been upheld. They did not want that.
No I'm not wrong - that legislation HAS NOT been declared UN-Constitutional - and if it has - you need to show me some proof.
