Conscience clauses are legal clauses attached to laws in some parts of the United States and other countries which permit pharmacists, physicians, and/or other providers of health care not to provide certain medical services for reasons of religion or conscience. In many cases, the clauses also permit health care providers to refuse to refer patients to unopposed providers. Those who choose not to refer or provide services may not be disciplined or discriminated against. The provision is most frequently enacted in connection with issues relating to reproduction, such as abortion, sterilization, contraception, and stem cell based treatments, but may include any phase of patient care.
The earliest national conscience clause law in the United States, which was enacted immediately following the Supreme Court's decision in Roe v. Wade, applied only to abortion and sterilization. It was sponsored by Senator Frank Church of Idaho. The Church Amendment, passed by the Senate on a vote of 92-1, exempted private hospitals receiving federal funds under the Hill-Burton Act, Medicare and Medicaid from any requirement to provide abortions or sterilizations when they objected on “the basis of religious beliefs or moral convictions.” Nearly every state enacted similar legislation by the end of the decade—often with the support of legislators who otherwise supported abortion rights. Supreme Court Justice Harry Blackmun, the author of the Roe v. Wade majority opinion, endorsed such clauses “appropriate protection” for individual physicians and denominational hospital.
