JUSTICE O'CONNOR, dissenting.
I agree with JUSTICE SCALIA that a faithful interpretation of the Eleventh Amendment embodies a concept of state sovereignty which limits the power of Congress to abrogate States' immunity when acting pursuant to the Commerce Clause. But that view does not command a majority of the Court, thus necessitating an inquiry as to whether Congress intended in CERCLA, 42 U.S.C. § 9601 et seq., and SARA, Pub.L. 99-499, 100 Stat. 1613, to abrogate the States' Eleventh Amendment immunity. On that question, I join Part I of JUSTICE WHITE's opinion. I also join Parts II, III, and IV of JUSTICE SCALIA's opinion concurring in part and dissenting in part.
