ORDER

Appellant’s motion to dismiss is GRANTED. The appeal is

DISMISSED with prejudice, each party to bear its own costs.

The opinion of the three-judge panel, reported at 469 F.3d 826

(9th Cir. 2006), is VACATED. 

BYBEE, Circuit Judge, with whom CALLAHAN, Circuit

Judge joins, concurring: 

I concur in the dismissal of the appeal pursuant to Fed. R.

App. P. 42(b) and in the vacatur of the panel opinion. I write

separately because I believe that this situation presents a very

different set of considerations from the cases discussed in

Judge Thomas’s partial dissent. 

This case involves a challenge to the United States Department of Agriculture’s (“USDA”) decision not to adopt a draft

policy that would have provided guidance to various regulated

entities on the treatment of nonhuman primates under the Animal Welfare Act. When USDA ultimately decided to abandon

the draft policy, the Animal Legal Defense Fund (“ALDF”)

filed suit alleging that USDA’s decision was arbitrary, capricious, and an abuse of discretion. The district court granted

USDA’s motion to dismiss, and ALDF timely appealed. Over

a vigorous dissent, a panel of this court reversed the district

court. Animal Legal Def. Fund v. Veneman, 469 F.3d 826 (9th

Cir. 2006). 

After a sua sponte call, a majority of the active judges

voted to rehear the case en banc. In a published order we

stated that “[t]he three-judge panel opinion shall not be cited

as precedent by or to this court or any district court of the

Ninth Circuit, except to the extent adopted by the en banc

court.” Animal Legal Def. Fund v. Veneman, 482 F.3d 1156

(9th Cir. 2007). The case is currently calendared for argument

7042 ANIMAL LEGAL DEFENSE v. VENEMAN
on June 18, 2007. We were informed by the parties on May

10, 2007, that they had reached a settlement and had agreed

to dismiss the case with prejudice “provided that the panel’s

opinion and judgment are vacated.” 

A majority of the en banc panel has agreed to grant the

motion to dismiss and vacate the panel’s opinion. Six members of the en banc panel, relying on U.S. Bancorp Mortgage

Co. v. Bonner Mall P’ship, 513 U.S. 18, 26 (1994), Karcher

v. May, 484 U.S. 72 (1987), Clarendon Ltd. v. Nu-West

Indus., Inc., 936 F.2d 127, 129 (3d Cir. 1991), and Matter of

Mem’l Hosp. of Iowa County, Inc., 862 F.2d 1299, 1300 (7th

Cir. 1988), would not vacate the panel’s opinion because

“voluntary settlement by the parties does not justify vacatur.”

Dissent at 7049. None of the cases cited in Judge Thomas’s

dissent, however, addresses the question before us: Having

granted rehearing en banc, may we vacate our own panel

opinion when the parties settle the case prior to reargument?

The cases cited by the dissent all involve a request that the

Supreme Court (or a court of appeals) vacate a lower court

opinion. Bonner Mall involved the question of “whether

appellate courts . . . should vacate civil judgments of subordinate courts in cases that are settled after appeal is filed or certiorari sought.” 513 U.S. at 19 (emphasis added). The Court

declined to vacate our decision on the motion of the parties,

holding that there were no “exceptional circumstances” justifying such an order. Id. at 29. Similarly, in Karcher, the

Supreme Court dismissed the appeal when plaintiff office

holders’ successors in office declined to pursue the appeal,

but rejected the plaintiffs’ argument “that if we dismiss the

appeal we must vacate the judgments below.” 484 U.S. at 81.

Clarendon and Memorial Hospital both involve situations

where the court of appeals was asked to vacate the decision

of the district court pursuant to the parties’ settlement agreement; both courts concluded that vacatur was not appropriate.

Clarendon, 936 F.2d at 129; Mem’l Hosp., 862 F.2d at 1300.

But cf. Nat’l Union Fire Ins. v. Seafirst Corp., 891 F.2d 762,

ANIMAL LEGAL DEFENSE v. VENEMAN 7043
768-69 (9th Cir. 1989) (rejecting “the Seventh Circuit’s rule

[in Memorial Hospital] to ‘always deny these motions’ . . . .

We find some merit in those sentiments but decline to adopt

such an inflexible rule. To do so would raise the cost of settlement too high. The better view, in our opinion, is to consider

the equities and hardships in resolving the question.”); 13A

CHARLES ALAN WRIGHT, ARTHUR R. MILLER, EDWARD H.

COOPER, FEDERAL PRACTICE & PROCEDURE § 3533.10 at 432 (2d

ed. 1984) (“The parties should remain free to settle on terms

that require vacation of the judgment.”); Id. at 763 (Supp.

2007) (discussing a decision to vacate the panel decision after

rehearing en banc had been granted, but before oral argument

and noting: “The fact that rehearing had been granted may

justify the further decision to vacate the panel decision, since

it shows at least some ground for concern with the panel decision. This setting also may reduce the risk that one party is

seeking to buy its way out of an adverse precedent.”). 

The parties have not asked us to vacate the district court’s

opinion, a request that would fall squarely within Bonner

Mall. Rather, we have been asked to vacate our own opinion,

an opinion that we have already ordered not be cited as precedent. The marginal difference between what we have already

ordered—that the panel opinion not be cited as precedent—

and what the parties have jointly requested—that we formally

vacate the opinion—is minuscule. 

Moreover, the parties have not requested anything extraordinary. It is common practice among the courts of appeals to

vacate the panel opinion in the order granting rehearing en

banc. See, e.g., Official Comm. of Unsecured Creditors of

Cybergenics Corp. v. Chinery, 310 F.3d 785 (3d Cir. 2002)

(“having voted for rehearing en banc in the above appeal, it

is ordered that the Clerk of this Court vacate the opinion and

judgment [of the panel].”) (emphasis omitted); Amos v. Maryland Dept. of Pub. Safety & Corr. Serv., 205 F.3d 687 (4th

Cir. 2000) (“After a majority of the active judges of this Court

voted to grant the . . . petition for rehearing en banc, we

7044 ANIMAL LEGAL DEFENSE v. VENEMAN
vacated [the panel’s] judgment); Byrne v. Butler, 845 F.2d

501, 507 (5th Cir. 1988) (en banc) (“[t]he grant of a rehearing

en banc vacates the panel opinion, which thereafter has no

force.”) (internal quotation marks and citations omitted);

E.E.O.C. v. Jefferson County Sheriff’s Dept., 2006 WL

3298341 (6th Cir. 2006) (en banc) (“The effect of the granting

of a hearing en banc shall be to vacate the previous opinion

and judgment of this court.”); United States v. Hardman, 260

F.3d 1199 (10th Cir. 2001) (en banc) (ordering sua sponte

rehearing of three cases and ordering that “[t]he panel opinions in these cases are vacated”); Freund v. Butterworth, 135

F.3d 1419, 1420 (11th Cir. 1998) (en banc) (“[I]t is ordered

that the above cause shall be reheard by this court en banc.

The previous panel’s opinion is hereby vacated.”); United

States v. Powell, —F.3d—, 2007 WL 1119641, *1 (D.C. Cir.

2007) (en banc) (“Upon the Government’s motion, the full

court vacated [the panel] decision and granted rehearing en

banc.”); Kirkendall v. Dept. of Army, 159 Fed. Appx. 193,

194 (Fed Cir. 2006) (en banc) (“The petition for rehearing en

banc is granted. The court vacates the panel’s judgment and

original opinion.”).1

Moreover, this widely accepted practice used to be our

practice as well. See Burlington N. & Santa Fe Ry. v. Int’l Bd.

of Teamsters, 185 F.3d 1075 (9th Cir. 1999) (ordering the

case be reheard en banc; “The three-judge panel opinion . . .

is withdrawn.”); In re Gruntz, 177 F.3d 729 (9th Cir. 1999)

(same); Hose v. INS, 161 F.3d 1225 (9th Cir. 1998) (same).

Judge Thomas indicates that we changed our practice in

response to the practices of West Publishing, which often

1The First Circuit appears to grant en banc rehearing only on certain

specified issues and decides on a case-by-case basis which portions of the

original panel opinion to vacate. See, e.g., United States v. Padilla, 403

F.3d 780 (1st Cir. 2005); Narragansett Indian Tribe v. Rhode Island, 415

F.3d 134, 135 (1st Cir. 2005). This is possible because of the circuit’s

small body of case law and the fact that there are only six active members

of the court. I have not been able to find a definitive example of the Second, Seventh or Eighth Circuits’ practice. 

ANIMAL LEGAL DEFENSE v. VENEMAN 7045
deletes the vacated opinion from its electronic databases and

declines to print them in the bound volumes of the Federal

Reporter.

2

 Dissent at 7049 n.1. Although we now declare the

panel opinions “not precedential,” we do not formally vacate

them, apparently so that West will not wipe them from the

annals of F.3d. I fully agree with Judge Thomas that there are

good reasons for wanting a complete case history in the

reporters, but we may wish to take this up with West instead

of altering our en banc practice. In any event, whatever concerns we have had in the past about altering history by wiping

panel opinions from the books are not realized in this case.

The panel’s opinion is published in 469 F.3d, which is already

in a hardbound edition. 

Our previous practice and the practices of our sister circuits

make eminent sense. When we decide to rehear a case en

banc, as the name suggests, we rehear the case and issue a

new opinion and judgment on behalf of the court. In effect,

we start over again. By granting rehearing en banc, we are not

engaging in another level of appellate review. We do not

affirm or reverse the panel; rather, we review the judgment of

the lower court. Any decision we issue necessarily displaces

whatever judgment and opinion the panel previously issued,

whether or not it is consistent with the en banc opinion. It

only stands to reason, then, that when the en banc court

assumes control of the case, we either vacate the underlying

judgment and opinion or treat them as vacated.3

In this case then, we are in a posture similar to settlement

on the eve of oral argument. We do not hesitate to grant such

2Although historically West removed vacated opinions from its database, this practice may have recently changed. It appears that the full text

of several recent opinions that have been vacated is still in its online

Westlaw database. 

3

In cases in which we have ordered en banc review, LEXIS treats the

panel opinion as having been vacated. For example, the LEXIS citation for

this case, 469 F.3d 826, contains the following notation: “NOTICE: THIS

OPINION WAS VACATED BY THE COURT.” 

7046 ANIMAL LEGAL DEFENSE v. VENEMAN
settlements, irrespective of the importance of the issues or the

time and preparation the panel has expended. See Amos, 205

F.3d at 687 (noting the court had granted rehearing and

vacated the judgment; dismissing the case when, five days

before oral argument en banc, the parties settled). When we

dismiss the appeal, we will not, in accordance with Bonner

Mall, vacate the district court’s opinion without good reason.

Here, consistent with Bonner Mall, the parties have not

requested that we vacate the district court’s opinion. Indeed,

they have asked that we leave the district court opinion in

place by formally vacating the three-judge panel’s opinion,

which we have already declared non-precedential. 

In this case the parties jointly ask us to do what we have

historically done and what our sister circuits routinely do—

strip a panel opinion of its precedential and persuasive authority by vacating it en banc. The request will facilitate settlement in this case, and I do not think the request is out of line.

But I think it would be unfair to do as the dissent proposes,

to dismiss the appeal, but not vacate the panel opinion. Effectively, we are not being asked “to vacate because the case [is]

moot, but . . . to vacate to make the case moot.” Nat’l Union

Fire Ins., 891 F.2d at 768. Because we do not know if the parties would agree to dismissal absent vacatur, it would be manifestly unfair to the parties to grant the motion, but on terms

different from those they agreed to. In my view, if we were

to refuse to vacate the panel opinion, as the parties have

requested pursuant to their settlement, the only fair course of

action would be to deny the motion on grounds of the inappropriateness of vacatur and proceed with en banc reargument. Adopting the dissent’s halfway approach would result

only in inequitable treatment of the parties and a disregard for

our colleagues who voted to take this case en banc. 

For the above reasons, I concur in the order. 

ANIMAL LEGAL DEFENSE v. VENEMAN 7047
THOMAS, Circuit Judge, with whom HAWKINS, 

MCKEOWN, WARDLAW, GOULD, and FISHER, Circuit

Judges join, concurring in part and dissenting in part: 

I concur in the dismissal of the appeal pursuant to Fed. R.

App. P. 42(b). However, I respectfully dissent from the portion of the order vacating the panel opinion. 

In this case, neither party filed a petition for rehearing en

banc. Rather, we decided sua sponte to rehear the case. Following the order granting rehearing en banc, ALDF filed a

motion to dismiss its appeal pursuant to Fed. R. App. 42(b).

Its reasons were purely tactical: It did not want to expend the

time and commit the resources to prepare for an en banc argument, and it did not wish to risk an adverse en banc result. In

the normal course, if we had simply granted the motion, the

appeal would be dismissed and the judgment of the district

court would remain intact. Under such a circumstance,

although the panel opinion would remain as part of the record,

it would be subject to our usual order filed when rehearing en

banc is granted, which provides that the panel opinion is designated as a non-precedential decision. See ALDF v. Veneman, 482 F.3d 1156 (9th Cir. 2007) (“The three-judge panel

opinion shall not be cited as precedent by or to this court or

any district court of the Ninth Circuit, except to the extent

adopted by the en banc court.”). 

One would think that the government would be entirely satisfied with that outcome. It had, after all, acquiesced in the

precedential, published panel opinion by declining to seek

rehearing. Our sua sponte decision to rehear its case gave the

government an immediate windfall; by our operating rules,

the opinion had been designated as non-precedential, so the

government was left in a much better position than it would

have been had we left the parties to their own devices. However, the government asked for something more. It conditioned its consent to dismissal on the en banc court’s entering

an order vacating the panel decision. 

7048 ANIMAL LEGAL DEFENSE v. VENEMAN
Vacatur is an “extraordinary remedy.” U.S. Bancorp Mortgage Co. v. Bonner Mall P’ship, 513 U.S. 18, 26 (1994). It

removes all precedential value from a decision, rendering an

opinion a legal nullity. Id. at 22. “[T]he general rule [is] that

when a court vacates an order previously entered, the legal

status is the same as if the order never existed.” United States

v. Jerry, 487 F.2d 600, 607 (3d Cir. 1973). If the opinion has

not been published in book form, an order vacating the opinion may prevent it from ever being published.1

 In that event,

the opinion may be lost from the historical record of the case;

it is certainly lost as a means of developing the law because

even its value as non-precedential persuasive authority is

removed. For all these reasons, the party seeking vacatur carries a burden of establishing equitable entitlement to vacatur.

Bonner Mall, 513 U.S. at 26.

Of course, vacatur is entirely appropriate if a case has “become moot due to circumstances unattributable to any of the

parties.” Karcher v. May, 484 U.S. 72, 83 (1987). However,

the Supreme Court has made it quite clear that voluntary settlement by the parties does not justify vacatur, even when the

1

See Judith Resnik, Whose Judgment? Vacating Judgments, Preferences

for Settlement, and the Role of Adjudication at the Close of the Twentieth

Century, 41 UCLA L. Rev. 1471, 1499 (1994) (describing the practices of

West Publishing Company). In fact, it was in part the fact that vacated

opinions sometimes vanished from the historical record that caused us to

alter our form order granting rehearing en banc to omit any reference to

vacating the panel opinion and to substitute our current language which

simply designates the opinions as non-precedential. West’s practice when

it encounters a vacatur order is to issue a notation withdrawing the opinion

from its bound volume. See, e.g., Finau v. INS, 277 F.3d 1146 (9th Cir.

2002) (“The opinion of the United States Court of Appeals, Ninth Circuit,

in Finau v. INS, published in the advance sheet at this citation, 277 F.3d

1146, was withdrawn from the bound volume because decision was withdrawn and vacated.”). In the digital age, of course, some vacated opinions

remain in electronic circulation and, if the opinion is vacated after it has

been published in the official reporters, it remains “on the books.” However, if this occurs, it is a matter of chance, not the product of deliberate

choice. 

ANIMAL LEGAL DEFENSE v. VENEMAN 7049
settlement agreement calls for vacatur. Bonner Mall, 513 U.S.

at 29. The Supreme Court has also held that a party’s change

of litigating heart does not justify vacatur. In Karcher, the

Supreme Court considered a case much like the one at bar.

The plaintiff office-holders were replaced, and their successors declined to pursue the appeal. The Supreme Court dismissed the appeal but declined to vacate the underlying

decisions. Karcher, 484 U.S. at 83 (“This controversy did not

become moot due to circumstances unattributable to any of

the parties. The controversy ended when the losing party—the

New Jersey Legislature—declined to pursue its appeal.

Accordingly, the Munsingwear procedure is inapplicable to

this case.”). 

Karcher and Bonner Mall specifically confronted the question of whether one court should be permitted to vacate an

opinion of a different, subordinate court. Here, an en banc

panel of this court has been asked to vacate the opinion of a

three-judge panel of the same court. However, there is no

principled distinction to be drawn between those situations,

particularly where, as here, none of the three judges on the

initial panel is a member of the en banc panel, meaning that

none of the affected judges has a vote in the decision on vacatur. There is no suggestion in Bonner Mall that vacatur is an

“extraordinary remedy” only some of the time. Indeed, once

we consider the justifications underlying the Supreme Court’s

holdings, it becomes perfectly clear that there is no meaningful distinction between the situation we face and the situation

the Supreme Court confronted. 

One of the important reasons for courts to decline vacatur

at the invitation of the parties is the preservation of public

trust. As the Supreme Court put it in Bonner Mall: 

As always when federal courts contemplate equitable

relief, our holding must also take account of the public interest. “Judicial precedents are presumptively

correct and valuable to the legal community as a

7050 ANIMAL LEGAL DEFENSE v. VENEMAN
whole. They are not merely the property of private

litigants and should stand unless a court concludes

that the public interest would be served by a vacatur.” 

513 U.S. at 26 (quoting Izumi Seimitsu Kogyo Kabushiki

Kaisha v. U.S. Philips Corp., 510 U.S. 27, 40 (1993) (Stevens, J., dissenting)). Chief Judge Easterbrook put it more

forcefully in Matter of Memorial Hosp. of Iowa County, Inc.,

862 F.2d 1299, 1300 (7th Cir. 1988): 

[A]n opinion is a public act of the government,

which may not be expunged by private agreement.

History cannot be rewritten. There is no common

law writ of erasure. 

An important aspect of maintaining the public trust is to

assure that the judicial process is transparent. Eradicating historical precedent is antithetical to that goal. 

Indeed, the act of eradication in this case might prove to be

misleading. An affirmative vote of the majority of the nonrecused members of our court to rehear a case en banc does

not necessarily signify any particular outcome. The justification for rehearing a case en banc under Fed. R. App. P. 35 is

based on whether rehearing is necessary to maintain uniformity of the court’s decisions or whether the proceeding

involves a question of exceptional importance. A judge’s vote

for or against rehearing en banc does not indicate that judge’s

vote on the merits. Indeed, in the last full year for which we

have complete data, fully 30% of the decisions of the en banc

panel were in accord with the original decision of the threejudge panel. Because our en banc panel has not considered

this appeal on the merits, vacatur leaves the incorrect and misleading impression that the en banc panel has considered and

ruled on the merits of the three-judge panel opinion.2

2For these reasons, I must respectfully disagree with the concurrence’s

suggestion that if we denied vacatur, it would be somehow unfair to those

ANIMAL LEGAL DEFENSE v. VENEMAN 7051
A second compelling reason to avoid entering an order of

vacatur at the invitation of the parties is that it gives the

appearance, and perhaps the reality in some cases, of allowing

the parties to manipulate court precedent. As Judge Easterbrook stated: 

When a clash between genuine adversaries produces

a precedent, however, the judicial system ought not

allow the social value of that precedent, created at

cost to the public and other litigants, to be a bargaining chip in the process of settlement. The precedent,

a public act of a public official, is not the parties’

property. We would not approve a settlement that

required us to publish (or depublish) one of our own

opinions, or to strike a portion of its reasoning.

Id. at 1302 (emphasis added). The Third Circuit agreed with

this assessment, stating: 

As should be self-evident even without reference to

the terms of Rule 42(b), action by the court can be

neither purchased nor parleyed by the parties. It follows that a judicial act by an appellate court, such as

vacating an order or opinion of this court or the trial

court, is a substantive disposition which can be taken

only if the appellate court determines that such

action is warranted on the merits. A provision for

such action in a settlement agreement cannot bind

the court. 

Clarendon Ltd. v. Nu-West Indus., Inc., 936 F.2d 127, 129 (3d

Cir. 1991) (emphasis added).3 As the Supreme Court stated in

Bonner Mall: 

who voted for rehearing en banc. Those who voted to rehear the case have

obtained precisely what our procedure provides in the order designating

the panel opinion non-precedential. Any further equitable relief would be

an affirmative remedy. 

3Notably, these quotations demonstrate that neither the Third Circuit nor

the Seventh Circuit sees any principled difference between a court vacat7052 ANIMAL LEGAL DEFENSE v. VENEMAN
Congress has prescribed a primary route, by appeal

as of right and certiorari, through which parties may

seek relief from the legal consequences of judicial

judgments. To allow a party who steps off the statutory path to employ the secondary remedy of vacatur

as a refined form of collateral attack on the judgment

would—quite apart from any considerations of fairness to the parties—disturb the orderly operation of

the federal judicial system. 

513 U.S. at 27. 

In the case before us, the posture of the parties gives the

very real appearance of attempted manipulation. The only

rationale given by ALDF for filing its dismissal motion is that

it just doesn’t want to spend any time or resources on the case.4

ALDF had not previously exhibited any litigation fatigue,

having aggressively pursued the case through the district court

and then on appeal. However, after a majority of the active

non-recused judges voted to rehear the case en banc, it apparently became suddenly tired. The motion to dismiss at this

ing a judgment of another court and a court vacating its own judgment.

Nor do I, especially when we are in the posture of sitting en banc and

vacating a panel decision. 

4ALDF’s motion states: “Here, plaintiffs-appellants request that this

appeal be dismissed because (1) the underlying case involves an extremely

unusual set of circumstances that is unlikely to be replicated in future

cases; (2) plaintiffs do not know which of the many issues raised by

USDA, NABR, or Judge Kozinski will be the focus of the en banc proceeding, which will make it extremely difficult for the plaintiffs to prepare

for the hearing; (3) neither the USDA nor NABR initially sought rehearing

en banc; and (4) under all of these circumstances, the plaintiffs-appellants

do not wish to spend additional time and resources litigating this case.”

ALDF’s motion continues: “In addition, plaintiff-appellants are willing to

have the panel decision in this case vacated and the district court’s decision reinstated as the final decision in this case. Counsel for the USDA

and counsel for NABR have stated that they do not oppose the motion

under these conditions.” 

ANIMAL LEGAL DEFENSE v. VENEMAN 7053
stage, coupled with ALDF’s stated willingness to vacate the

panel opinion, leaves one with the impression that it was willing to trade off what it thought was “good” precedent to avoid

the risk of a “bad” decision from the en banc panel. On the

other side, the government does not simply wish to have the

district court judgment reaffirmed and the panel opinion designated as non-precedential; it asks us to expunge the panel

decision from the historical record, to make it as inaccessible

and non-citeable as possible. Of course, I may well be mistaken, but those are the impressions I draw from the motions

filed by the parties. 

The parties are certainly entitled to pursue their own litigating tactics. But when those strategies depend on us rewriting

our own judicial history, we must hesitate before lending our

imprimatur. We depend on the public’s confidence in the

independence and integrity of our judgments. When parties,

rather than the courts, shape precedent and process according

to their private agreements or actions, public confidence is

inevitably eroded. Parties should not be allowed, nor should

we appear to allow them, to manipulate our jurisprudence. 

Worse, in this case, is the fact that we acted sua sponte to

rehear the case. The parties’ collaboration to attempt to prevent rehearing en banc gives the appearance that the parties

have been bargaining with the Court regarding the terms

under which the Court would withdraw its sua sponte rehearing order. 

Finally, the action to vacate the opinion infringes on the

rights of our colleagues on the three-judge panel. One of the

most important rights we have as Article III judges is the right

to publish our decisions. Judges of our Court retain this right

when they are in dissent. Indeed, by custom and through our

General Orders, a dissenting judge can force publication of a

disposition originally designated as an unpublished, nonprecedential decision. Judges of our Court can register their

views by publishing a dissent from a decision not to rehear a

7054 ANIMAL LEGAL DEFENSE v. VENEMAN
case en banc. Vacatur removes this right. It reduces an opinion originally intended for publication by the author to a

lesser status even than decisions that the panel has affirmatively decided are not precedent-worthy. This is particularly

true since, as of January 1, 2007, we must now allow parties

to cite even unpublished dispositions and unpublished orders

as persuasive authority. 9th Cir. R. 36-3(b). For this reason,

out of a sense of respect and collegiality to our colleagues, we

must employ the extraordinary remedy of vacatur with great

care when sitting en banc. 

Despite these powerful considerations, I do not quarrel with

the en banc panel’s power to vacate the prior opinion. We

have not adopted the approach of the Seventh, Third, and

D.C. Circuits, which prohibits vacatur at the behest of the parties in all circumstances. In re Memorial Hosp., 862 F.2d at

1300; Clarendon, 936 F.2d at 129; In re United States, 927

F.2d 626, 628 (D.C. Cir. 1991). As we made clear in Nat’l

Union Fire Ins. v. Seafirst Corp., the limitations on vacatur

are “neither statutorily nor constitutionally required.” 891

F.2d 762, 766 (9th Cir. 1989). 

Rather, we have—in a manner consistent with the teachings

of Bonner Mall—considered vacatur on its own equitable

merits, making our assessment on “the equities and hardships” involved in the particular case. Id. at 769; see also

Ringsby Truck Lines v. Western Conference of Teamsters, 686

F.2d 720, 722 (9th Cir. 1982). 

There are, of course, cases in which the particular “equities

and hardships,” id., would rise to the level of “exceptional circumstances,” Bonner Mall, 513 U.S. at 29, justifying vacatur

of an opinion in the context of a settlement between the parties. Indeed, there is an overarching equitable consideration

that will be present and powerful in any such case: the considerable societal value in encouraging settlements and finality

in litigation.5 However, the fact of settlement alone is an

ANIMAL LEGAL DEFENSE v. VENEMAN 7055
insufficient rationale. As the Tenth Circuit put it when considering and rejecting a similar request by the parties to vacate

a circuit court decision: 

The court is, of course, impressed with the importance of salutary settlements of controversies, with

their consequent lessening of both the burden on the

parties of costly litigation and the drain on judicial

resources. Nevertheless, we are seriously troubled by

the effort here, made for whatever reason, to cause

the withdrawal of an opinion of this court and the

nullification of its precedential effect. This arrangement of the parties, which would affect the precedent

of this court, goes beyond the rationale of vacatur as

explained in Munsingwear, i.e., to protect against

future preclusive collateral estoppel effects on the

parties to litigation, and reaches out to deprive our

opinion of any precedential effect. Judge Posner has

succinctly stated that the Seventh Circuit rejects such

requests: “We vacate unappealable decisions, to prevent them from having a preclusive effect. We do

not vacate opinions, to prevent them from having a

precedential effect.” In re Smith, 964 F.2d 636, 638

(7th Cir. 1992). 

Oklahoma Radio Assocs. v. F.D.I.C., 3 F.3d 1436, 1437 (10th

Cir. 1993). 

There will, no doubt, be occasions in which vacatur is a

desirable means to effect a satisfactory resolution of a dispute.

But the parties here do not even offer that consideration as a

rationale. The parties have not settled their disputes in any

respect; they just wish us to apply an eraser to this appeal so

they can litigate the same questions another day. Indeed, their

only point of accord is that we should vacate all of the appellate proceedings and treat them as if they never existed. 

And what has the government offered in this case to meet

its burden of justifying the extraordinary remedy of vacatur?

7056 ANIMAL LEGAL DEFENSE v. VENEMAN
Nothing. It simply refused to consent to dismissal unless the

panel opinion was vacated. No other rationale was offered.

The bare threat of refusing to consent to a voluntary dismissal

cannot possibly be sufficient to justify invoking the equitable

remedy of vacatur, particularly when the government’s consent is not required to dismiss this appeal. See Fed R. App. P.

42(b) (“An appeal may be dismissed on the appellant’s

motion on terms agreed to by the parties or fixed by the

court.”). The government’s position and ALDF’s acquiescence in it may be founded in a view that judicial opinions

are, as the Seventh Circuit put it, “the parties’ property.”

Mem’l Hosp., 862 F.2d at 1302. But they are not. The Seventh

Circuit rejected this notion, and so should we. Rather than

blithely accepting ALDF’s expression of weariness and the

government’s insistence on removing all vestiges of what it

considers unfavorable precedent from the historical record,

we ought to assess the vacatur request carefully, fully, and on

its own merits, as would be consistent with our case law, Seafirst, 891 F.2d at 769, and Bonner Mall. 

But we have done nothing of the sort in this case. We have

not done a merits analysis. We have not performed an equitable balancing. We have not assessed whether the government

has satisfied its burden to establish equitable entitlement to

the extraordinary remedy of vacatur. 

The concurrence defends the vacatur decision on the basis

that some of our sister circuits issue, as a matter of practice,

rehearing orders that vacate the panel opinions—as our circuit

used to do. That practice, however, is of no significance in the

context of the present discussion. Those orders are not entered

at the behest of the parties; they are entered with the presumption that the en banc court will proceed to rehear the case on

the merits and will issue an alternative opinion that will be

both reasoned and precedential. Vacatur of published decisions at the behest of settling litigants is an entirely different

matter. 

ANIMAL LEGAL DEFENSE v. VENEMAN 7057
We have two very thoughtful panel opinions in this case:

the majority opinion by Judge Fletcher and the dissent of

Judge Kozinski. We owe them more respect than to toss their

opinions into the judicial scrapheap in an attempt to expunge

them from the historical record purely for the parties’ litigation convenience. As Judge Easterbrook put it when confronting a similar situation in Memorial Hospital: 

The opinions written in this case record two judges’

solutions to a legal problem. These opinions may be

valuable for other litigants and judges; they may also

be useful to Memorial itself at another time. They

will be left as they are. 

862 F.2d at 1303. 

I would leave the panel opinions just as they are. Although

we have designated the opinions as non-precedential and left

the district court judgment as the final judgment in this action,

the written opinions are an important part of the historical

record.6 Our precedent requires us to perform an equitable

balancing of interests in deciding whether to employ the

extraordinary remedy of vacatur. We have not done so, and

the parties have not provided us with any reason but desire.

6When the full court designates a panel opinion as non-precedential in

the course of granting rehearing en banc, it is engaging in a fundamentally

different process than when a panel elects to designate its own decision as

non-precedential. In the latter case, the panel has made the reasoned decision that the disposition does not qualify for publication within the criteria

set forth in Ninth Circuit Rule 36-2. However, when rehearing en banc is

granted as to an opinion that has already been designated as precedential

by the panel, the en banc panel is simply removing the precedential effect

of the decision so that the en banc panel has the opportunity to revisit the

merits and so that the panel’s decision (which may be subject to revision)

will not bind other panels of the Court while the case is being reheard. In

such cases, the panel has already made the affirmative determination that

its decision is worthy of publication. Thus, the published panel opinion

was in no sense advisory or deemed unworthy of publication when it was

rendered in the course of deciding this case. 

7058 ANIMAL LEGAL DEFENSE v. VENEMAN
I respectfully dissent from that portion of the order that

directs vacatur of the panel opinion.
