Whether AEDPA permitted federal habeas relief on the ground that the Michigan Supreme Court unreasonably applied the Double Jeopardy Clause when it upheld the mistrial declaration.
Holding
No. Even if the trial judge may have erred, the Michigan Supreme Court's conclusion that she did not abuse her discretion was not an objectively unreasonable application of clearly established Supreme Court precedent.
Reasoning
AEDPA does not authorize a federal court to grant habeas relief merely because it independently believes the state court decided a constitutional question incorrectly. Under 28 U.S.C. § 2254(d)(1), the state decision must be contrary to, or an objectively unreasonable application of, clearly established federal law as determined by the Supreme Court. That is a substantially more demanding standard than ordinary appellate review.
The relevant constitutional rule comes from United States v. Perez and later double-jeopardy cases: a retrial after a mistrial is permitted if there was a high degree of necessity, and the trial judge exercised sound discretion. A genuinely deadlocked jury is the classic justification for a mistrial, and a trial judge's determination that a jury is deadlocked receives great deference because the judge is best situated to assess whether further deliberation would be useful or coercive.
The Court stressed that Supreme Court precedent does not impose a rigid checklist before a judge may declare a deadlock mistrial. A judge need not require deliberations for a set minimum time, poll each juror, consult counsel, issue a supplemental instruction, consider specified alternatives, make an express finding of manifest necessity, or place every consideration on the record. The judge's discretion is not unlimited, but the Constitution does not prescribe those procedures.
The record supported more than one reasonable interpretation. The jury had deliberated after a short, uncomplicated trial; its notes could be read as indicating substantial disagreement; and the foreperson expressly answered that the jury would not reach a unanimous verdict. Although the judge could have inquired further or allowed more deliberation, the Michigan Supreme Court could reasonably view the exchange as supporting a finding of deadlock.
AEDPA adds a second layer of restraint to the deference ordinarily due a trial judge's deadlock determination. Because the governing sound-discretion standard is general and permits reasonable disagreement in application, state courts have broader latitude. The Sixth Circuit improperly substituted its own view of ambiguous facts for the Michigan Supreme Court's reasonable view.
