Whether the challengers showed a sufficient likelihood of success to support preliminary injunctive relief against Montana's physician-only abortion law.
Holding
No. The Ninth Circuit erred in concluding that the challengers had a fair chance of establishing that the law imposed an undue burden on access to abortion.
Reasoning
Casey defines an undue burden as a regulation that has the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion. The District Court found insufficient evidence that requiring a licensed physician to perform abortions would, in practical terms, create such an obstacle. The Ninth Circuit did not dispute that factual conclusion.
The Ninth Circuit instead relied on the possibility that the Legislature acted with an improper purpose. But the Supreme Court found no evidence supporting the inference that Montana enacted the physician-only rule to create a substantial obstacle to abortion. Courts do not presume unconstitutional legislative intent even when a statute causes harmful effects; they certainly should not presume it where the record showed no substantial obstructive effect.
The evidence cited by the challengers did not establish an unlawful purpose. That medical studies may show physician assistants to be as safe as physicians does not invalidate the law, because Casey recognized that States have broad latitude to reserve particular functions for licensed professionals even when others could competently perform them. The fact that an antiabortion group drafted the law likewise did not prove the Legislature's purpose in enacting it.
Although Cahill was the only nonphysician affected by the statute, that fact did not show a purpose to obstruct abortion access. Under the prior arrangement, Cahill could perform abortions only with a licensed physician present, and the new rule therefore did not require women to seek care at a different facility. The narrow practical effect supported the District Court's conclusion that no substantial obstacle had been shown.
The Court's earlier decisions also consistently recognized a State's authority to limit the performance of abortions to physicians. Roe v. Wade stated that a State may proscribe abortions performed by persons who are not physicians; Connecticut v. Menillo held that prosecuting nonphysicians for performing abortions does not invade constitutionally protected privacy; and Casey upheld a physician-only requirement even for the less significant task of providing information to patients.
