ing them conflict with the Constitution.” Id., at 75–76. In the decades after Lochner, the Court struck down nearly 200 laws as violations of individual liberty, often over strong dissents contending that “[t]he criterion of constitutionality is not whether we believe the law to be for the public good.” Adkins v. Children’s Hospital of D. C., 261 U. S. 525, 570 (1923) (opinion of Holmes, J.). By empowering judges to elevate their own policy judgments to the status of constitutionally protected “liberty,” the Lochner line of cases left “no alternative to regarding the court as a… legislative chamber.” L.

Lee Optical of Okla., Inc., 348 U. S. 483, 488 (1955).
Rejecting Lochner does not require disavowing the doctrine of implied fundamental rights, and this Court has not done so. But to avoid repeating Lochner’s error of converting personal preferences into constitutional mandates, our modern substantive due process cases have stressed the need for “judicial self-restraint.” Collins v. Harker Heights, 503 U. S. 115, 125 (1992). Our precedents have required that implied fundamental rights be “objec-
