Without Congressional Action, An 1873 Law Could Result In A National Abortion Ban

On March 26, 2024, the Supreme Court heard oral arguments for U.S. Food and Drug Administration v. Alliance for Hippocratic Medicine which involves Food and Drug Administration (“FDA”) regulations of mifepristone, a drug that induces abortion.[1]  The case raises questions about the future of abortion access throughout the U.S. and, more broadly, the ability of courts to review and limit the FDA’s expert decision-making and regulating.[2]  During the oral arguments, two Justices were focused on a long-dormant law that could be used to ban abortion nationally with no action from congress: The Comstock Act.[3]

The Comstock Act is an anti-obscenity law originally passed in 1873.[4]  Section 2 of the original Act, now codified as 18 U.S.C. § 1461, provides that “[e]very article or thing designed, adapted, or intended for producing abortion, or for any indecent or immoral use . . . shall not be conveyed in the mails or delivered from any post office or by any letter carrier.”[5]  Despite the broad impact implied by the plain text of this section, the law has historically been construed narrowly.[6]  By the mid-1900s, the judiciary, legislature, and U.S. Postal Service reached a consensus interpretation: Section 1461, and the Comstock Act as a whole, does not “prohibit[] a sender from conveying [prohibited] items where the sender does not intend that they be used unlawfully.”[7]  The Biden Administration, in a 2022 memorandum from the Office of Legal Counsel, detailed this history and underscored that the Administration does not consider the Act to limit the lawful distribution of medication abortion, even in areas that restrict abortion access.[8]

The plaintiffs in Alliance for Hippocratic Medicine argue that the FDA’s 2021 decision not to enforce mifepristone in-person dispensing requirements violated the Comstock Act by “authoriz[ing] the widespread mailing and shipping of abortion drugs.”[9]  The District Court for the Northern District of Texas found this position persuasive, determining, in part, that the 2021 decision violated the plain text of the Comstock Act.[10]  While the merits of the Comstock Argument are not formally in front of the Supreme Court and the Fifth Circuit did not rule on the Comstock Act arguments, Justice Alito’s and Justice Thomas’ inquiries during oral arguments indicate that some members of the Supreme Court may issue opinions that reach the merits of these arguments.[11]  The FDA fielded Justice Alito’s implication that the agency should have considered Comstock in its 2021 decision by maintaining that it is not authorized to account for other laws when modifying such regulations.[12]  Justice Thomas asked mifepristone manufacturer Danco Laboratories, before the court as an intervenor-appellant on behalf of the FDA,[13] to respond to an argument that it faces a “Comstock problem” in shipping its product.[14]  Danco underscored that the issue was not presented below and noted that the Act “has not been enforced for nearly a hundred years.”[15]  Plaintiffs, however, countered that the “plain text” of the Comstock Act is “pretty clear.”[16]

Even if Alliance for Hippocratic Medicine is dismissed for lack of standing, the Comstock Act could spell danger for abortion access in every state.[17]  As the law is presently enacted, a presidential administration amenable to a different interpretation of the Act could enact a nationwide abortion ban.[18]  Likewise, a purely textualist interpretation of section 2 from the Supreme Court could have the same effect.[19]  Therefore, the best safeguard against a national ban would be for Congress to remove “abortion” from the Comstock Act.[20]  Such congressional action would not only resolve questions about the liabilities and responsibilities of the federal agencies regarding the mailing of all abortifacients, but it would also preclude any imposition of liability on private citizens and physicians.[21]

Access to safe abortions—and abortion medication—is access to healthcare.[22]  Thus, repealing the abortion provisions of the Comstock Act is a crucial measure in furthering public health and safety.[23]  Such legislative action would further be representative of the American public’s opinion, as 61 percent of Americans believe that abortion should be legal in all or most cases.[24]

[2] This essay focuses narrowly on the Comstock Act in the context of this case. It is crucial to note, however, that a decision invalidating the FDA’s actions could stand to destabilize the regulatory state and the availability of beneficial medications. See Wendy Parmet, Abortion Case Could Harm Womens’ Health and Upset Pharma Markets, Bʟᴏᴏᴍʙᴇʀɢ L. (Mar. 26, 2024, 4:30 AM), (discussing the Supreme Court’s recent reticence to afford administrative agencies deference as an “effort to dismantle the regulatory state” and noting that by disregarding the FDA’s scientific conclusions, “the Fifth Circuit opened the door to a judge withdrawing any drug based on their own non-expert opinion that some non-existent study might be helpful”).
