Whether Nebraska could ban the specified abortion method without an exception when the procedure was necessary, in appropriate medical judgment, to preserve the woman’s health.
Holding
No. The statute was unconstitutional because it lacked a health exception.
Reasoning
Casey reaffirmed that a State may regulate or proscribe abortion after viability only where the regulation includes an exception necessary, in appropriate medical judgment, to preserve the woman’s life or health. Because Nebraska’s law applied both before and after viability, and the State’s regulatory interest is weaker before viability, at minimum the same health protection was required for the law’s previability applications.
The health requirement was not limited to cases in which pregnancy itself endangered the woman. A State also may not regulate abortion methods in a way that exposes women to significant medical risks. Nebraska’s interest in expressing concern for fetal life, preventing perceived cruelty, or protecting medical ethics did not eliminate that constitutional limitation.
The trial record supported the conclusion that intact D&E could be safer than other methods for some patients. The District Court found that it could reduce the number of instrument passes, uterine or cervical injury, retained fetal tissue, infection, blood loss, and other complications. The American College of Obstetricians and Gynecologists likewise explained that the procedure could offer safety advantages in particular circumstances.
Nebraska emphasized that the procedure was uncommon, that alternatives were generally safe, and that no controlled comparative studies proved it was uniquely necessary. The Court held that these points did not establish that a health exception was unnecessary. Medical necessity does not demand absolute proof, unanimity among doctors, or a showing that no alternative exists; appropriate medical judgment permits responsible differences of medical opinion.
Where substantial medical authority concluded that banning a procedure could create greater health risks for some women, uncertainty itself did not justify the ban. If the procedure was in fact safer in particular cases, the absence of an exception would expose women to unnecessary and potentially serious harm; if it was not, the exception would simply have no practical use. The statute therefore had to include a health exception.
