concurring.
I join the opinion and judgment of the Court but add these few words. Had the Court of Appeals stated that as a matter of state law, the State Supreme Court’s summary, unexplained denial of an original petition for habeas corpus is a *807ruling on the merits, the presumption the Court’s opinion articulates in this case would be rebutted unless we disagreed with the Court of Appeals with respect to state law. The Court of Appeals, however, did not so state but in effect said that the state court’s order was ambiguous. Hence, the presumption governs.
I also note that Coleman v. Thompson, ante, at 739, stated that the presumption of Harris v. Reed, 489 U. S. 255 (1989), “applies only when it fairly appears that a state-court judgment rested primarily on federal law or was interwoven with federal law, that is, in those cases where a federal court has good reason to question whether there is an independent and adequate state ground for the decision.” In joining the Court’s opinion in the case before us, I take it that the opinion’s bobtailed quotation from Coleman, ante, at 802, is not intended to restrict the reach of the presumption.
