Roberts, C. J., dissenting
U. S. 97, 105 (1934).
Allowing unelected federal judges to select which unenumerated rights rank as “fundamental”–and to strike down state laws on the basis of that determination–raises obvious concerns about the judicial role. Our precedents have accordingly insisted that judges “exercise the utmost care” in identifying implied fundamental rights, “lest the liberty protected by the Due Process Clause be subtly transformed into the policy preferences of the Members of this Court.” Washington v.

In a dissent that has outlasted the majority opinion, Justice Curtis explained that when the “fixed rules which govern the interpretation of laws [are] abandoned, and the theoretical
