Whether the Court had jurisdiction over Jackson's postarraignment statement despite the Michigan Supreme Court's separate state-law ruling suppressing several earlier statements.
Holding
Yes. The admissibility of Jackson's seventh, postarraignment statement turned on the Michigan Supreme Court's federal Sixth Amendment analysis and was properly before the Court.
Reasoning
Jackson argued that certiorari should be dismissed because the Michigan Supreme Court had also suppressed several of his earlier statements under a state statute governing prearraignment delay. The Court rejected that argument because the state-law ruling did not govern the seventh statement at issue here.
Although suppression of the earlier statements meant that Jackson's conviction would be reversed regardless of the federal ruling, the Michigan court's treatment of the seventh statement rested on its Sixth Amendment analysis. The Court could therefore review that distinct federal question.
