life, liberty, or property. See, e.g., Johnson v. United States, 576 U. S. 591, 623 (2015) (Thomas, J., concurring in judgment). Other sources, by contrast, suggest that “due process of law” prohibited legislatures “from authorizing the deprivation of a person’s life, liberty, or property without providing him the customary procedures to which freemen were entitled by the old law of England.” United States v. Vaello Madero, 596 U. S. ___, ____ (2022) (Thomas, J., concurring) (slip op., at 3) (internal quotation marks omitted). Either way, the Due Process Clause at most guarantees process. It does not, as the Court’s substantive due process cases suppose, “forbi[d] the government to infringe certain ‘fundamental’ liberty interests at all, no matter what process is provided.” Reno v. Flores, 507 U. S. 292, 302 (1993); see also, e.g., Collins v. Harker Heights, 503 U. S. 115, 125 (1992).
As I have previously explained, “substantive due process” is an oxymoron that “lack[s] any basis in the Constitution.” Johnson, 576 U. S., at 607–608 (opinion of Thomas, J.); see also, e.g., Vaello Madero, 596 U. S., at ___ (Thomas, J., concurring) (slip op., at 3) (“[T]ext and history provide little support for modern substantive due process doctrine”). “The notion that a constitutional provision that guarantees only ‘process’ before a person is deprived of life, liberty, or property could define the substance of those rights strains credulity for even the most casual user of words.” McDonald v. Chicago, 561 U. S. 742, 811 (2010) (Thomas, J., concurring in part and concurring in judgment); see also United States v. Carlton, 512 U. S. 26, 40 (1994) (Scalia, J., concurring in judgment). The resolution of this case is thus straightforward. Because the Due Process Clause does not secure any substantive rights, it does not secure a right to abortion.
The Court today declines to disturb substantive due process jurisprudence generally or the doctrine’s application in other, specific contexts. Cases like Griswold v. Connecticut,
