The decision reads that:
"The Constitution makes no express reference to a right to obtain an abortion, but several constitutional provisions have been offered as potential homes for an implicit constitutional right. Roe held that the abortion right is part of a right to privacy that springs from the First, Fourth, Fifth, Ninth, and Fourteenth Amendments. See 410 U. S., at 152–153. The Casey Court grounded its decision solely on the theory that the right to obtain an abortion is part of the 'liberty' protected by the Fourteenth Amendment’s Due Process Clause. Others have suggested that support can be found in the Fourteenth Amendment’s Equal Protection Clause, but that theory is squarely foreclosed by the Court’s precedents, which establish that a State’s regulation of abortion is not a sex-based classification and is thus not subject to the heightened scrutiny that applies to such classifications."
