KIE: On April 14, 1983, federal district court judge Gerhard Gesell overturned, as "arbitrary and capricious," a Department of Health and Human Services regulation that required hospitals to post notices concerning the illegality of denying life-saving care to handicapped infants and encouraged anyone with knowledge of such a case to report it to HHS via a telephone hotline. This article reviews the evolution and implementation of the HHS regulation, the legal challenge to it, and the judge's ruling.
