David Hackett Souter, Schad v. Arizona — Opinion of the Court
“ In cases, like this one, involving state criminal statutes, the dissent's "statutory alternatives" test runs afoul of the fundamental principle that we are not free to substitute our own interpretations of state statutes for those of a State's courts. If a State's courts have determined that certain statutory alternatives are mere means of committing a single offense, rather than independent elements of the crime, we simply are not at liberty to ignore that determination and conclude that the alternatives are, in fact, independent elements under state law. ”
