JUSTICE O'CONNOR, concurring.
I join the opinion of the Court, and I agree that the State's failure to properly raise its challenge to our negative Commerce Clause jurisprudence supports a decision not to pass on the merits of this claim. Ante this page. I further note, however, that the State does nothing that would persuade me to reconsider or abandon our well-established body of negative Commerce Clause jurisprudence.
