Sandra Day O'Connor,
Hilton v. South Carolina Public Railways Commission…
“ The Court's distinction is untenable. The clear statement rule is not a mere canon of statutory interpretation. Instead, it derives from the Constitution itself. The rule protects the balance of power between the States and the Federal Government struck by the Constitution. Although the Eleventh Amendment spells out one aspect of that balance of power, the principle of federalism underlying the Amendment pervades the constitutional structure: The Constitution gives Congress only limited power to govern the Nation; the States retain power to govern locally. ”
