                     Filed January 15, 2010

 Before: William C. Canby, Jr. and Kim McLane Wardlaw,
    Circuit Judges, and Richard Mills,* District Judge.


                             ORDER

   This order addresses procedural issues that arose after the
filing of our opinion in this matter on July 21, 2009. See
United States v. Payton, 573 F.3d 859 (9th Cir. 2009). The
issues primarily concern post-opinion mootness and the ques-
tion whether our opinion should be vacated and the appeal
dismissed as moot. We deny vacatur and dismissal.

  Our opinion held that a search of Payton’s computer was
unlawful, and we accordingly reversed the denial of Payton’s
motion to suppress the fruits of that search. We remanded
with instructions to permit Payton to withdraw his conditional
guilty plea. See id. at 864-65.

   After our opinion was filed, the government asked for and
received an extension of time to September 3, 2009, to file a

  *The Honorable Richard Mills, United States District Judge for the
Central District of Illinois, sitting by designation.

                               1191
1192                UNITED STATES v. PAYTON
petition for rehearing. The government subsequently decided
not to file a petition, and the September 3 deadline passed. On
September 8, our Clerk’s office issued our mandate, two days
early. See Fed. R. App. P. 41(b). The mandate was transmitted
to the district court and still appears in its docket. That same
day, a judge of our court issued a stop-clock order to our
Clerk, which has the effect under our General Orders of
extending by 14 days the time to call for rehearing en banc.
G.O. 5.4(e). The stop-clock order was timely, having been
issued within seven days of the expiration of time for filing
petitions for rehearing. G.O. 5.4(d), (e). Recognizing that the
mandate had been issued prematurely, our Clerk’s office
deleted as erroneous the entry in our docket showing that the
mandate had issued. The record does not reflect that this cor-
rection was sent to or reached the district court.

   On September 16, the judge who had stopped the clock cal-
led sua sponte for a vote to rehear the case en banc, and
requested briefing by the parties as to rehearing en banc. That
briefing was ordered on September 21 and was completed by
November 4.

   Meanwhile, however, on September 14, Payton had moved
in district court to withdraw his conditional plea of guilty,
pursuant to the mandate from this court that was entered in
the district court docket. Relying on that mandate, the govern-
ment did not oppose the motion and it was granted. The gov-
ernment then moved to dismiss the case and the district court
granted the motion.

  The government recited these events in its supplemental en
banc brief, indicating that the case was finished in the district
court. The government further stated that, although it dis-
agreed with our opinion, it did not seek en banc review
because, among other reasons, it believed that the decision
would “have minimal impact” on law enforcement.

   At this point, the judge seeking en banc review noted, cor-
rectly, that the case had become moot, and asked our panel to
                   UNITED STATES v. PAYTON                   1193
vacate its decision and dismiss the appeal as moot. The panel
declined to vacate and dismiss for the following reasons.

   First, the mootness did not arise while the decision on
appeal was pending, or even while a petition for rehearing
was pending. It did not arise because of some external event.
It arose because the government, accepting the consequences
of our adverse opinion and the mandate that had been entered
in the district court, unilaterally determined to dismiss the
case. It is true that the mandate was issued in error, but even
if we deem the issuance ineffective, that does not change our
result. If we vacate our decision in these circumstances, then
a party that suffers an adverse opinion from our court can
escape the estoppel or precedential consequences of the
adverse decision by carrying it out before our mandate prop-
erly issues. This precise scenario was anticipated in Armster
v. United States District Court, 806 F.2d 1347 (9th Cir. 1986),
in which we refused mandamus to vacate an earlier decision
on the ground of post-decision mootness allegedly caused by
a change in the government’s administrative position. We
explained:

    Implicitly, the Justice Department urges us to adopt
    a new uniform rule, viz. when a losing party acts in
    accordance with an appellate court’s decision before
    it becomes “final,” that decision becomes ipso jure
    moot . . . .

    . . . [T]he new rule suggested by the Justice Depart-
    ment would encourage manipulation of the judicial
    system by wrong-doers. It would allow them to seek
    the benefits of a favorable judicial decision but
    escape some of the more significant adverse conse-
    quences of an unfavorable judgment. In the case of
    the government, heads of administrative agencies
    and other public officials could as a matter of course
    cause the withdrawal of decisions establishing unfa-
    vorable precedents or vindicating individual rights
1194                   UNITED STATES v. PAYTON
      by complying with those decisions before the man-
      date issues. Such a result would be inconsistent with
      the manner in which our system of checks and bal-
      ances is intended to operate. Accordingly, we reject
      the Justice Department’s suggestion.

Id. at 1355-56. The same observation has been made by the
Third Circuit en banc, Finberg v. Sullivan, 658 F.2d 93, 97
n.6 (3d Cir. 1981) (“We fear that granting defendants’ motion
for vacation of judgment might have the undesirable conse-
quence in future cases of encouraging the losing party on
appeal to seek to delay the issuance of the mandate and in the
interim bring about, for the sole purpose of evading the unfa-
vorable decision, events which moot the case.”).1

   Other circuits also have declined to dismiss for mootness
after an opinion has been handed down, even though the
mootness arose before a mandate was issued. In Bastien v.
Senator Ben Nighthorse Campbell, 409 F.3d 1234 (10th Cir.
2005), Senator Campbell moved to vacate a decision and dis-
miss an appeal because his Senate term ended and he was
sued in his capacity as senator. The court denied the motion,
pointing out that the case had not been moot when the opinion
was handed down. Id. at 1235. The fact that the mandate had
not issued was “inconsequential.” Id. The court also relied on
the Second Circuit’s ruling in In re Grand Jury Investigation,
399 F.3d 527 (2d Cir. 2005). There the Second Circuit stated:
  1
    In re Pattullo, 271 F.3d 898 (9th Cir. 2001), does not hold to the con-
trary. Pattullo involved mootness that arose when the district court dis-
missed a Chapter 13 bankruptcy proceeding that was the subject of a
pending appeal in our court. The dismissal occurred prior to our issuance
of a memorandum disposition (although we were not notified until after
the disposition was filed). We vacated and dismissed because there was no
district court proceeding on which our decision could operate. Id. at 901.
We also stated in dictum that “[e]ven after an appellate court has issued
its decision, if it has not yet issued its mandate and the case becomes
moot, the court will vacate its decision and dismiss the appeal as moot.”
Id. at 900-01. Application of Pattullo’s dictum in the circumstances of the
present case would clearly be inconsistent with Armster.
                       UNITED STATES v. PAYTON                        1195
      At least in the civil context, vacatur of a previously
      issued decision of a court of appeals is not constitu-
      tionally mandated, and indeed is typically inappro-
      priate, when the appeal is subsequently mooted due
      to settlement between the parties or the losing
      party’s unilateral actions. We generally have discre-
      tion, moreover, to leave our order intact where the
      circumstances leading to mootness occur after we
      file our decision but before the mandate has issued.

Id. at 529 n.1 (internal citation omitted).2

   It is true that, when a case becomes moot in a court of
appeal prior to decision, its mootness ordinarily requires not
only dismissal of the appeal but vacatur of the district court
opinion being appealed. See United States v. Munsingwear,
Inc., 340 U.S. 36, 39-40 (1950). But even in that circum-
stance, the Supreme Court has rejected mandatory vacatur
when mootness is caused by a voluntary settlement. U.S. Ban-
corp Mortgage Co. v. Bonner Mall Partnership, 513 U.S. 18
(1994). “The principal condition to which we have looked is
whether the party seeking relief from the judgment below
caused the mootness by voluntary action.” Id. at 24. In
reviewing U.S. Bancorp and other Supreme Court cases, the
Third Circuit concluded that they “demonstrate that the deci-
sion whether or not to vacate a previously issued decision is
within our discretion based on equity.” Humphreys v. DEA,
105 F.3d 112, 114 (3d Cir. 1996). Exercising that discretion,
the Third Circuit refused to vacate a decision overturning the
  2
    The only circuit court decisions we have found to the contrary are
those of the Fifth Circuit in United States v. Caraway, 483 F.2d 215 (5th
Cir. 1973) (en banc), and United States v. Miller, 271 F.3d 898 (5th Cir.
2001) (per curiam order). In Caraway, a district court dismissed the under-
lying indictment in accord with the Fifth Circuit’s decision before its man-
date issued. The Fifth Circuit vacated its decision and dismissed the appeal
as moot, over the dissent of four judges. With all due respect, we find the
positions of the Second, Third and Tenth Circuits, and our own binding
decision in Armster, more persuasive than that of the Fifth Circuit.
1196                  UNITED STATES v. PAYTON
DEA’s revocation of a physician’s prescription license even
though the physician died before the appellate mandate
issued. It noted:

      The DEA was not due further review as a matter of
      right. All three remaining avenues of further review
      are discretionary: panel reconsideration, en banc
      rehearing and certiorari by the Supreme Court. Thus,
      there is no threat that the DEA will be affected by a
      reviewable but unreviewed decision that was not
      reviewed due only to happenstance.

Id. at 115 (footnote omitted).3

   In Payton, the situation is even more strongly against a dis-
cretionary vacatur. To summarize the major reasons:

   First. The mootness in this case arose after our decision
was issued (and, indeed, after the time for a petition for
rehearing had run). Our case is therefore distinguishable from
such cases as Arizonans for Official English v. Arizona, 520
U.S. 43, 59-60 (1997), and Munsingwear, 340 U.S. at 37,
where mootness occurred prior to decision. Our case was a
live controversy when we decided it.

   Second. The mootness was brought about by the voluntary
act of the party losing the decision now sought to be vacated.
The government’s act, although undertaken in the justifiable
belief that our mandate had properly issued, was nevertheless
voluntary because the mandate required only that Payton be
allowed to withdraw his conditional guilty plea. It did not
  3
   The Third Circuit also called attention, 105 F.3d at 114, to an even
more extreme instance, where the Supreme Court denied rehearing of its
celebrated decision in Robinson v. California, 370 U.S. 660 (1962), over
a dissent urging that the decision should be vacated as moot because it
turned out that the appellant had died before the Supreme Court heard his
appeal. 371 U.S. 905 (1962).
                    UNITED STATES v. PAYTON                  1197
require the government to dismiss its charges, a decision
within its prosecutorial judgment. Mootness caused by the
unilateral action of a losing party is ordinarily not a ground
for vacatur of the decision establishing the loss. See U.S. Ban-
corp, 513 U.S. at 26.

   Third. Even if mootness were deemed to have been precipi-
tated inexorably by our mandate, that fact can hardly amount
to the kind of external “happenstance” requiring vacatur in
fairness to a party “frustrated by the vagaries of circum-
stance.” Id. at 25. Losing an appeal and dismissing charges in
light of that loss can hardly be deemed external to the case.

   Fourth and last. The government was deprived of no
opportunity to contest our decision. It appealed, briefed and
argued its position, and made a conscious decision not to peti-
tion for rehearing of our adverse decision after receiving an
extension of time.
   It is true that our refusal to vacate the decision after it has
become moot deprives a member of our court of the right to
seek sua sponte an en banc rehearing in order to obtain a dif-
ferent decision on the merits (although it leaves open the
opportunity to seek an en banc rehearing for the purpose of
vacating our decision). We do not minimize that right, but
have concluded that it does not overcome the equities we have
described and does not justify erasing a decision that the panel
issued when the controversy was still live, and that the parties
have complied with and are content to let stand.
   For all these reasons our panel declined to vacate its deci-
sion and dismiss the appeal as moot. The judge who initially
sought en banc review then called for an en banc vote to
rehear the matter for the purpose of vacating the decision as
moot and dismissing the appeal. A vote was taken and the
matter failed to receive a majority of the votes of the non-
recused active judges in favor of en banc consideration. See
Fed. R. App. P. 35.
