That was fast. The Supreme Court has reversed the Ninth Circuit’s decision in Ryan v. Wood, the lethal injection case. The order states:

The application to vacate the judgment of the United States Court of Appeals for the Ninth Circuit granting a conditional preliminary injunction, presented to Justice Kennedy and by him referred to the Court, is granted. The district judge did not abuse his discretion in denying Wood’s motion for a preliminary injunction. The judgment of the United States Court of Appeals for the Ninth Circuit reversing the district court and granting a conditional preliminary injunction is vacated.

UPDATE: I assume that, as a matter of precedent, this takes the Ninth Circuit decision off the books but does not actually decide the underlying issues of First Amendment law or remedies law.
