Whether mandamus should issue to vacate the District Court's discovery orders before the officials first pursue a more specific privilege claim and request in camera review.
Holding
No. Mandamus was inappropriate because the officials had an adequate, less drastic means of seeking the protection they wanted in the District Court.
Reasoning
Mandamus is an extraordinary remedy, reserved for exceptional circumstances such as a judicial usurpation of power or a failure to exercise required authority. A petitioner must show both that no other adequate means of relief exists and that the right to the writ is clear and indisputable. Its issuance also remains substantially discretionary with the court asked to grant it.
Those demanding standards protect the final-judgment rule and discourage piecemeal appellate litigation. Routine use of mandamus to review interlocutory discovery disputes would undermine Congress's general judgment that appellate review should await final judgment, while also imposing significant burdens on trial judges and already crowded court dockets.
The officials did not seek a categorical ruling that all requested records were absolutely privileged. Rather, they wanted the District Court to make an informed, document-specific determination, through in camera review, whether the plaintiffs' need outweighed the State's confidentiality interests.
The Ninth Circuit's denial of mandamus did not foreclose that relief. Its opinion left the officials free to return to the District Court, have responsible officials assert governmental privilege with particularity as to specific documents or categories, and request in camera inspection. That path could provide precisely the tailored protection the officials sought without resort to the extraordinary writ.
In camera review was particularly appropriate because the asserted confidentiality interests could be serious but would vary by document. Disclosure might chill internal communications, expose confidential sources, or compromise prison-system and personnel records. Review by the trial judge in chambers is a relatively low-cost way to balance those interests against the prisoners' demonstrated need for discovery. The Court read the Ninth Circuit's unexplained denial concerning prisoner files as leaving the same avenue open there as well.
