For more than two decades, states have been adding to the things that physicians must say and do to obtain “informed consent” — and thereby testing the constitutional limits of states' power to regulate medical practice. In 1992, the Supreme Court upheld states' authority to require physicians to provide truthful information that might encourage a woman to reconsider her decision to have an abortion, finding that such a requirement did not place an “undue burden” on the woman.
