I have criticized the proposed attempts by Republicans in Congress to enact tort reform legislation (particularly a medical malpractice bill) here, here, here, here, here, here, here, here and here.
Now here is some criticism from the right. "Tea Party" supporter Rob Natelson of the Independence Institute in Colorado, has been described as the first conservative legal scholar to forcefully argue that federally imposed limits on medical malpractice and other health care-related lawsuits are unconstitutional. See this letter back in April and this article back in May.
