Arizona v. Washington

1978-02-21

Headline: Decision allows retrial after a mistrial for prejudicial defense remarks, reversing a habeas bar and giving trial judges deference when they conclude juror impartiality may be compromised.

Holding: The Court reversed, holding that a state trial judge’s responsible grant of a mistrial for prejudicial defense statements can allow retrial even without an explicit on-the-record "manifest necessity" finding because appellate deference is warranted.

Real World Impact:

Permits retrial when a judge finds likely juror bias from prejudicial remarks.
Gives trial judges more leeway to stop misconduct without automatically blocking retrial.
Makes federal post-conviction courts less likely to bar retrial for missing on-record formalities.

Summary

Background

A man convicted of killing a hotel clerk was granted a new trial by an Arizona court after prosecutors had failed to turn over evidence. At the second trial, the defense lawyer told the jury that the prosecutor had hidden statements and that the Arizona Supreme Court had ordered a new trial for that reason. The prosecutor moved for a mistrial; the trial judge granted it but did not use the words "manifest necessity" or fully explain alternatives. A federal judge later barred retrial on double jeopardy grounds and the Ninth Circuit affirmed.

Reasoning

The Supreme Court asked whether the record showed the kind of necessity that allows a mistrial without barring retrial, and whether the judge’s failure to state detailed reasons on the record was fatal. The Court held that a trial judge who responsibly concludes that prejudicial remarks may have tainted jurors is entitled to substantial deference. Because the judge gave both sides a full hearing and the record showed careful consideration, the lack of the exact phrase "manifest necessity" did not make the mistrial unconstitutional.

Real world impact

The ruling means prosecutors may retry cases after a judge grants a mistrial for likely juror bias from improper statements, even if the judge did not recite a magic formula on the record. Judges still must exercise sound discretion; but federal habeas courts cannot automatically block retrials for the mere absence of a specific on-the-record phrase.

Dissents or concurrances

Two Justices dissented, arguing the record was too silent to imply necessity and that the defendant’s protection against double jeopardy should bar retrial. Another Justice simply agreed with the result.
