Title X of the Public Health Service Act provides federal funding for family-planning services. Section 1008 of the statute specifies that none of the federal funds provided under Title X are to be “used in programswhere abortion is a method of family planning.” In 1988, the Secretary of Health and Human Servicesissued new regulations that, among other things, prohibited family-planning services that receive Title X funds from engaging in counseling concerning the use of abortion as a method of family planning, referrals for abortion as a method of family planning, and activities amounting to encouragement or advocacy of abortion as a method of family planning. Various Title X grantees and physicians supervising Title X funds challenged the validity of the regulations and sought an injunction against their implementation. Were the regulations a permissible interpretation of Section 1008? Did the regulations violate constitutional guarantees?
