It would likely run into a 10th Amendment challenge from the states. If it passes, it will be interesting for the courts, since conservatives generally favor states rights and put more emphasis on the 10th Amendment. (See the current healthcare debate and the desire to give states flexibility.) Liberals favor the right to sue with no damage limits but also like federal power. IF it passes, it would be a case with a good chance for the Supreme Court to take since it involves an issue that is getting some attention. It would be interesting how they would vote on it because as I said it puts both liberals and conservatives in a situation where their most basic beliefs are in conflict.
However, the more I see the more I have a feeling that big malpractice awards might just be our best friend. That is what keeps hospitals in many cases from hiring specialty trained physicians over mid-levels or lesser trained physicians. Without that concern, it makes the lower cost labor source more attractive. It is all about the bottom line, if you think they care about "quality of care" you are insane. They are also not generally really smart at looking at efficiency and more indirect costs. If they think they can hire some guy with "state minimum training" for half the cost with no downside, they will do that. Or more likely, a guy with a Family Med residency for 75% of the cost.
I also think the elimination of "joint and several" liability is bad for physicians - particularly EM physicians - and probably comes from the hospital lobby. Now, even if it is a big award, EM physicians are generally in the clear because attorneys will go after the "deep pockets" of the hospital when it comes time to collect. If it is based on degree of fault, that puts a much bigger target on the physician, and if they don't have any other choice they will go after the physician's assets. Now it almost never happens because it is not worth the effort, and there are more fruitful targets. So that is a very bad provision for us.
There is one fundamental rule of medical economics: Things never work out the way you expect. What you often think is you best friend ends up your worst nightmare (see Anesthesiologists and CRNA's.) I just have a bad "spidey sense."
