"It is tempting to identify the Court’s invention of a constitutional right to abortion in Roe v. Wade, 410 U. S. 113 , as the tipping point that transformed third-party standing doctrine and the tiers of scrutiny into an unworkable morass of special exceptions and arbitrary applications. But those roots run deeper, to the very notion that some constitutional rights demand preferential treatment. During the Lochner era, the Court considered the right to contract and other economic liberties to be fundamental requirements of due process of law. See Lochner v. New York, 198 U. S. 45 (1905) . The Court in 1937 repudiated Lochner’s foundations. See West Coast Hotel Co. v. Parrish, 300 U. S. 379 –387, 400 (1937). But the Court then created a new taxonomy of preferred rights."
