The full court has been advised of the petition for rehearing en banc and no judge of the court has requested a vote on whether to rehear the matter en banc. Fed. RApp. P. 35.
The petition for rehearing and the petition for rehearing en banc, filed March 20, 2002, are DENIED.
OPINION
Petitioner-appellee seeks a writ of habe-as corpus in this capital case, claiming, among other things, ineffective assistance by his trial counsel. Because of petitioner’s ineffective assistance claim, the magistrate judgе allowed discovery by the State of materials that would ordinarily have been subject to evidentiary privileges, including the attorney client privilege. Over the State’s objection, the magistrate judge also entered a protective order limiting the State’s use of the materials. The district *1038 court denied the State’s motion to reconsider the magistrate judge’s order, and the State appeals that denial.
We hold thаt the district court’s denial of the motion to reconsider is an appeal-able collateral order. We further hold that the denial of the motion was not clear error and, accordingly, affirm the district court.
I. Background
Petitioner-appellee Lance Ian Osband was convicted of first-degree murder in a California state court and sentenced to death. The California Supreme Court affirmed the judgment,
see People v. Osband, 13
Cal.4th 622,
Osband’s petition asserted numerous claims of ineffective assistance of counsel, including a claim that counsel was inadequate in the development and presentation of evidence regarding Osband’s mental health. The magistrate judge granted the State’s motion for discovery on these claims, finding that “petitioner has waived attorney/client privilege and work product protection with respect to all documents relevant to his ineffective assistance of counsel claims.” The magistrate judge also found that, given the allegations relating to mental health evidence, “any privilege for petitioner’s communications with non-testifying mental health professionals has been waived.”
The magistrate judge allowed discovery of trial counsel’s files and of the records of two mental health examiners, but it entered a protective order restricting use of these documents by the State. The order, entered over the State’s objection, read as follows:
All documents produced to respondent pursuant to respondent’s motion to discover trial counsel’s file and the mental health examinations of Drs. Yarvis and Hutchinson, prepared at trial counsel’s request in preparation for trial, shall be deemed to be confidential. These documents may be used only by representatives from the Office of the California Attorney General and may be used only for purposes of any proceedings incident to the petition for writ of habeas corpus pending before this Court. Disclosure of the contents of the documents and the documents themselves may not be made to any other persons or agencies, including any law enforcement or prosecutorial personnel or agencies without an order from this Court. This order shall continue in effect after the conclusion of the habeas corpus proceedings and specifically shall apply in the event of a retrial of all or any portion of pеtitioner’s criminal case.
The State moved in the district court for reconsideration of the magistrate judge’s order. Applying the clear error standard of 28 U.S.C. § 636(b)(1)(A), the district court denied the motion. The district court emphasized that under our en banc opinion in
McDowell v. Calderon,
The State timely appealed the district court’s denial of its motion to reconsider the magistrate judge’s order.
*1039 II. Appellate Jurisdiction
As an initial matter, petitionerappellee Osband argues that we lack subject matter jurisdiction over the State’s appeal. We disagree. While neither the protective order nor the district court’s denial of the motion to reconsider is a final judgment on the merits of the case, we have jurisdiction pursuant to 28 U.S.C. § 1291 under the “collateral order doctrine.”
See Cohen v. Beneficial Indus. Loan Corp.,
We have previously heard an interlocutory appeal of a protective order in a case very similar to this one. In
Wharton v. Calderon,
We held in
Wharton
that the protective order was an appealable collateral order. Paraphrasing the Supreme Court in
Swint v. Chambers County Commission,
First, the protective order is the “conclusive” determination by the district court of the legal issue in question. The petitionеr in
Wharton
conceded that the protective order was conclusive, but petitioner in this case does not. Osband points out that the district court noted that, should the need arise, the State could seek modification of the order to avoid prejudice. This is true, but the protective order in
Wharton
is, in this respect, not different in substance from the order in this case. A party subject to a protective order is generally freе to return to the issuing court to seek modification of the order.
See Empire Blue Cross & Blue Shield v. Janet Greeson’s A Place For Us,
In any event, thе issue in this appeal is not whether prejudice to the State might, at some future date, lead to modification of the order. The issue is, rather, the underlying legal basis of the order. The State argues that under
Anderson v. Calderon,
The magistrate judge’s entry of the order, and the district court’s denial of the State’s motion to reconsider, are “conclusive” determinations that Osband’s ineffective assistance claim does not constitute an unqualified waiver of the attorney-client privilege, and that the federal court has the power to prohibit use of the discovered materials on retrial in state court. These were conclusive determinations that the magistrate judge “possessed the legal authority to issue the [protective] order.”
Jackson v. Vasquez,
Second, the protective order in this case resоlves an “important” issue • “separate from the merits” of the underlying action. The importance of the issue presented is beyond doubt. The validity of protective orders in such cases has been the subject of several opinions by this Court in recent years.
See, e.g., Anderson,
Osband does not dispute the importance of the issue. He argues, however, that the protective order is not separate from the merits of the habeas petition. He points out that a district court’s decision to grant discovery in a habeas case requires at least a preliminary review and favorable assessment of the merits of that case. From this he argues that the decisions to аllow discovery and to issue a protective order are “inextricably entwined with the district court’s ongoing assessment of the prima facie merits of Mr. Osband’s Sixth Amendment claim.” Petitioner-appellee’s brief at 14. If Osband is correct, we, decided Wharton incorrectly, for the identical argument was available in that case: Petitioner Wharton had sought federal habeas; he had alleged ineffective assistance of *1041 counsel; and the district court found petitioner’s claims sufficiently meritorious to allow discovery to proceed, subject to a protective order.
Whatever connection may exist between the merits of the habeas petition and the legal basis of the protective order, the order “is separable in the sense that the question of whether [the law permits] an order of such scope at this stage of the proсeedings will not be answered by the disposition of the pending [habeas proceeding].”
United States v. Spilotro,
Third, and finally, the protective order will be “effectively unreviewable on appeal” from a final judgment granting Osband’s petition. In arguing that this requirement from
Swint
is met, the Stаte points to the portion of the protective order that prohibits it from disclosing the discovered materials to “law enforcement and prosecutorial personnel” during the habeas proceeding, as well as thereafter. The State argues that the prohibition will hamper its ability to respond to the merits of the petitioner’s habeas claims of ineffective assistance of counsel. If the Statе is in fact prejudiced in its ability to defend against the habeas petition by this (or some other) aspect of the protective order, and if Osband prevails on the merits of his petition, it may indeed be impossible for the State to show that compliance with the protective order prejudiced its defense. For example, having never discussed the discovered materials with the “prosecutorial personnel” who prosecuted Osband, the State may never know how it could have done a better job in defending against the habeas petition if it had been able to discuss those materials with them. It therefore could never show prejudice. Further, even if the State could show prejudice, it is unlikely that this could serve as a ground for reversal of a grant of habeas. As we concluded in a very similar circumstance in
Wharton, “
‘the [State] will not bе able to show, on appeal from the final decision [from the grant of the habeas petition] that [it] was unfairly prejudiced in the habeas proceeding as a result of [its] compliance.’ ”
Because the protective order and the denial of the motion to reconsider the order satisfy the three requirements of the collateral order doctrine as articulated by the Supreme Court in
Swint,
we hold that the State’s appeal is properly before us. The district court’s denial of the motion to reconsider is “too important to be denied review and too independent of the cause itself to require that appellate consideration be deferred until the whole case is adjudicated.”
Cohen,
III. Standard of Review
A district judge may reconsider a magistrate’s order in a pretrial matter if that order is “clearly erroneous or contrary to law.” 28 U.S.C. § 636(b)(1)(A). We review a district court’s denial of a motion to reconsider a magistrate’s pretrial order under that same standard.
See Kulas v. Flores,
*1042 IV. Legality of the Protective Order
The State argues that the district court’s denial of the motion to reconsider conflicts with Ninth Circuit authority. We disagree. In declining to reconsider the magistrate’s protective order, the district court properly applied the law of this circuit- as set forth in our en banc decision in McDowell II.
The protective order in
McDowell I
and
II
was virtually identical to the protective order in this case. The order “stat[ed] that the Attorney General could use any documents produced from the trial counsel’s file only for purposes of the pending habeas litigation.”
McDowell II,
On rehearing en banc,- we disagreed, holding that “the district court did not commit clear error when it limited access to the file pursuant to the terms of the protective order.”
McDowell II,
Applying
McDowell II,
we hold in this case that the district court did not commit clear error in denying the motion to reconsider the protective order. While a petitioner in a habeas corpus action who raises a Sixth Amendment claim of ineffective assistance of counsel waives the attorney-client privilege as to the matters challenged,
see Wharton,
The State argues .that the protective order may unduly limit its ability to use the attorney-client-privileged materials in the event of a retrial in state court, and that the state rather than the federal court should determine the scope of the waiver on retrial. It is true that the order is designed to ensure that the prosecution on retrial will not use the discovery permitted in the habeas proceeding to circumvent the more limited discovery available in criminal prosecutions.
See McSurely v. McClellan,
In the posture of this case, however, the question is not whether the federal district court on habeas was correct in entering a protective order limiting the use of attorney-client material on retrial. The question before us is narrower. We are asked only to decide whether it was clear error for the district court to deny the motion for reсonsideration of such a protective order. The en banc panel in
McDowell II
provided the answer when presented with a virtually identical order: “The question being a debatable one, the district court did not commit clear error when it limited access ... pursuant to the terms of the protective order.”
The State finds support for its argument in
Anderson v. Calderon,
We refuse to accord to
Anderson
the weight the State would give it. To the extent
Anderson
is inconsistent with the statement of Ninth Circuit law set forth in
McDowell II,
we, of course, are bound by the en banc decision. “[A]n appellate panel simply cannot modify an En banc decision.”
Ewing v. Williams,
We therefore AFFIRM the ruling of the district court.
