Whether Missouri’s statutory declaration that life begins at conception was facially unconstitutional.
Holding
The Court declined to decide the preamble’s constitutionality because it had not been applied or threatened to be applied in a concrete way against the plaintiffs.
Reasoning
The preamble did not itself regulate abortions or directly govern the plaintiffs’ medical practice. At most, it expressed Missouri’s value judgment favoring childbirth, a judgment that prior cases recognized a State may make.
The provision directed Missouri law to be construed consistently with fetal interests, but its actual effect on other statutes and regulations depended on how Missouri courts would interpret it. Federal courts could not supply an authoritative state-law construction on a speculative record.
Because no concrete enforcement action or application was before the Court, a declaratory judgment would resolve an abstract dispute rather than a live constitutional controversy. The Court therefore left challenges to any future restrictive application for a future case.
