At what all surely must hope is the conclusion of this long running litigation, we must address an issue of some importance under Federal Rule of Appellate Procedure 37(b) relating to the award of post-judgment interest to the plaintiffs-ap-pellees on the punitive damages judgment they obtained against the 'defendants-appellants. This is a cautionary tale for all whose judgments on appeal are subject to the requirements of Rule 37(b).
In an earlier appeal, we reduced the punitive damages because we concluded they were excessive under the Supreme Court’s Due Process Clause jurisprudence. We accordingly directed the district court on remand to enter a judgment for the damage amounts we specified, assuming the plaintiffs opted not to have a new trial. Because our mandate did not contain instructions about the allowance of post-judgment interest as required by Rule 37(b), we are now called upon to decide whether the district court had the authority to award post-judgment interest from the date of its original judgment, as modified in its final judgment, or only from the date of that final judgment. We hold that our failure to specify the accrual date for post-judgment interest in our mandate *1016 precluded the district court’s order that interest would run from the date of the original judgment.
We conclude, however, that our omission of post-judgment interest was inadvertent, and we therefore recall the earlier mandate and amend it to provide for post-judgment interest from the date of the original judgment. In so doing, we caution that in the future, Rule 37(b)’s requirements as to the terms of our mandates should be noted and adhered to.
BACKGROUND
In 1995, four individual physicians and two clinics that provide medical services, including abortions, to women (collectively, “Physicians”) brought suit against American Coalition of Life Activists and 13 others (collectively, “ACLA”) for violating the Freedom of Access to Clinic Entrances Act (“FACE”), 18 U.S.C. § 248, and the Racketeer Influenced and Corrupt Organizations Act (“RICO”), 18 U.S.C. §§ 1961-68. The underlying facts giving rise to this long history of litigation are fully described in our en banc opinion, Planned Parenthood of the Columbia/Willamette, Inc. v. Am. Coalition of Life Activists, 290 F.3d 1058, 1062-66 (9th Cir.2002) (en banc) (hereinafter PPCW V).
The jury found for Physicians on all counts and awarded a total of $526,336.14 in compensatory damages under FACE, $108.5 million in punitive damages under FACE and $11.8 million in compensatory damages (after trebling) under RICO. See id. at 1066 n. 4. On February 22, 1999, the district court entered judgment against ACLA in the full amount of the jury’s verdict (“Original Judgment”). The Original Judgment also provided that “[e]ach plaintiff shall recover the aforementioned damages with interest thereon at the rate as provided by law, 28 U.S.C. § 1961.”
ACLA appealed the judgment, which we affirmed on rehearing en banc except as to punitive damages.
Id.
at 1088. We remanded for the district court “to consider in the first instance whether the award is appropriate in light” of
In re Exxon Valdez,
ACLA again appealed. We reduced the punitive damages award to a total of $4.7 million and remanded for the “district court to order a new trial unless [P]hysicians accept a remittitur in accord” with the amounts we specified.
Planned Parenthood of the Columbia/Willamette, Inc. v. Am. Coalition of Life Activists,
Physicians accepted the remittitur. On July 10, 2006, the district court entered judgment and awarded post-judgment interest on the entire award from the date of the Original Judgment (“Final Judgment”). ACLA appealed, challenging the district court’s authority to award post-judgment interest from the date of the Original Judgment because our mandate in PPCW VIII contained no instructions about the allowance of post-judgment interest.
JURISDICTION AND STANDARD OF REVIEW
We have jurisdiction to hear ACLA’s timely appeal from a final judgment. 28 U.S.C. § 1291. Because this case involves the proper construction of 28 U.S.C.
*1017
§ 1961 and Federal Rule of Appellate Procedure 37(b), our review is de novo.
See AT & T v. United Computer Sys., Inc.,
DISCUSSION
I
As a preliminary matter, ACLA contends that the district court’s award of post-judgment interest on the
entire
damages award from the date of the Original Judgment rather than the date of the Final Judgment was improper. We do not address this contention, because it is barred from reconsideration by the law of the case. “Nothing is before this court but what is subsequent to the mandate.”
Atlas Scraper & Eng’g Co. v. Pursche,
II
ACLA’s argument relies on two premises. First, ACLA contends that
Briggs v. Pennsylvania R.R. Co.,
A
Assessing ACLA’s first premise requires that we unravel the relationship between 28 U.S.C. § 1961 and
Kaiser Aluminum & Chemical Corp. v. Bonjorno,
Section 1961 provides for the mandatory award of post-judgment interest “on any money judgment in a civil case recovered in a district court.”
See Ford v. Alfaro,
Kaiser
and § 1961 explain how to determine the accrual date of post-judgment interest in the first instance.
Briggs
and Rule 37(b), on the other hand, limit the power of the district court to award post-judgment interest from any date other than the date of entry of judgment on remand when that is what our mandate requires. In
Briggs,
the district court entered judgment for the defendant notwithstanding the verdict after granting a motion to dismiss for lack of jurisdiction.
See
Rule 37 was promulgated as a reminder of the
Briggs
rule.
See
Advisory Committee Notes on Rule 37 (1967). When we “modif[y] or reverse[ ] a judgment with a direction that a money judgment be entered in the district court, [our] mandate must contain instructions about the allowance of interest.” Fed. R.App. P. 37(b). When our mandate lacks such instructions, the district court “ha[s] no power to enter judgment for an amount different than directed.”
Briggs,
Our canvass of the law has not disclosed a published case in this circuit—or in any other—where the district court was allowed to deviate from a mandate that directed the entry of a particular, modified money judgment and contained no instructions on post-judgment interest by awarding interest from the date of entry of the original judgment. None of the cases Physicians cite is to the contrary. For example, in
Kaiser
itself, the district court’s judgment was affirmed, so Rule 37(a), not Rule 37(b), was applicable.
See
Moreover,
Briggs
and Rule 37(b) limit only the power of the
district court
to deviate from the mandate. We remain free to amend our judgments or recall our mandates to award post-judgment interest as appropriate under
Kaiser
and § 1961. In the other cases Physicians cite, it was the
appellate court,
not the district court, that corrected its previous mandate to provide expressly for post-judgment interest from the date of the original judgment.
See Northrop Corp. v. Triad Int’l Mktg., S.A.,
Physicians contend that our circuit’s precedent does not require such a strict reading of
Briggs
and Rule 37(b) and devote considerable attention to
Mt. Hood Stages, Inc. v. Greyhound Corp.,
Physicians would have us infer from
Mt. Hood II
that the Ninth Circuit construes
Briggs
and Rule 37(b) differently from every other circuit. We do not agree, because
Mt. Hood II,
properly understood, speaks to neither. First, an earlier appeal had already affirmed the portion of the damages award that was not dependent on any tolling theory,
see id.
at 395, 406, so Rule 37(a), not Rule 37(b), governed post-judgment interest on those damages. Second,
Mt. Hood I
did not direct the entry of a particular, modified money judgment, but simply remanded to the district court to assess the equitable tolling theory.
See Mt. Hood II,
Physicians may have been led astray by language in
Mt. Hood II
suggesting that we take an expansive approach to the award of post-judgment interest.
See Mt. Hood II,
In sum, we hold that when we modify or reverse a judgment with a direction that a particular money judgment be entered on remand, and our mandate does not contain instructions about the allowance of post-judgment interest, Briggs and Rule 37(b) forbid the district court to award post-judgment interest from the date of the original judgment, even when such an award would otherwise be appropriate under Kaiser and § 1961.
B
ACLA is correct that
PPCW VIII
modified the district court’s Revised Judgment as to the amount of punitive damages and then directed that a particular money judgment be entered on remand.
PPCW VIII
“arrive[d] at a sum for each defendant to pay each plaintiff.”
Physicians urge that we follow
Stewart v. Donges,
We do not find Stewart to be apposite. Rule 37(b) actually had no bearing there because the court of appeals had previously “remanded the case for calculation of the exact amount [of attorney’s fees] to be awarded.” Id. at 381 (emphasis added). We, on the other hand, directed the district court on remand to enter a particular, modified money judgment — which is what the plain language of Rule 37(b) covers. Moreover, Physicians’ contention is inconsistent with the allocation of judicial authority contemplated by Briggs and Rule 37(b). When we modify or reverse a judgment with a direction that a money judgment be entered in the district court, “the mandate must contain instructions about the allowance of interest.” Fed. R.App. P. 37(b) (emphasis added). It is the court of appeals — not the district court — that is charged with setting the date that interest accrues on the damages we have specified.
Ill
We accept ACLA’s argument that the district court deviated from our mandate in
PPCW VIII
by awarding post-judgment interest on the reduced punitive damages award from the date of the Original Judgment rather than the date of the Final
*1021
Judgment. That does not end the matter, however, because we may recall our mandate and direct that post-judgment interest run from a date appropriate under
Kaiser
and § 1961.
See, e.g., Perkins,
A
We first must determine whether
PPCW VIII’s
reduced punitive damages award was meaningfully ascertained as of the Original Judgment. The Supreme Court has explained that “the purpose of post-judgment interest is to compensate the successful plaintiff for being deprived of compensation for the loss from the time between the ascertainment of the damage and the payment by the defendant.”
Kaiser,
We agree with Physicians that we should have awarded post-judgment interest from the date of the Original Judgment because the basis for the punitive damages award had already been meaningfully ascertained. As in
Guam Society,
our decision in
PPCW V
vacated the district court’s original judgment so that it could, consider intervening case law.
Compare Guam Soc’y,
Because the punitive damages award was meaningfully ascertained as of the Original Judgment, Physicians are entitled under § 1961 to post-judgment interest from that date.
B
Our opinion in PPCW VIII should have included instructions about the allowance of post-judgment interest, as Rule 37(b) requires. We therefore turn to the question of remedy.
The Advisory Committee Notes on Rule 37 state that “a party who conceives himself entitled to interest from a date other than the date of entry of judgment in accordance with the mandate should be entitled to seek recall of the mandate for
*1022
determination of the question.” The parties in
Turner,
Our authority to recall a mandate “cannot be questioned” and “may be exercised for good cause and to prevent injustice.”
Aerojet-Gen.,
That said, we recognize ACLA’s contention that Physicians should have sought recall of the mandate as soon as they realized that our mandate did not contain instructions about the allowance of post-judgment interest. However, we also recognize that our precedent in this area has not been entirely clear, and that we should have addressed post-judgment interest in our mandate. To avoid any injustice, therefore, we recall and amend our mandate to include instructions regarding the allowance of post-judgment interest as follows: On the reduced punitive damages award, post-judgment interest is to run from February 22, 1999, the date of the Original Judgment.
Henceforth, we expect that litigants in this circuit will clearly understand that if we modify or reverse a judgment with a direction that a money judgment be entered in the district court, our mandate must contain instructions about the allowance of post-judgment interest. Fed. R.App. 37(b). If our mandate omits such instructions, a party that believes it is entitled to interest from a date other than the date of entry of judgment on remand must expeditiously seek reform of the mandate.
Mandate shall issue in accordance with this opinion. Each party shall bear its own costs on appeal.
REMANDED.
Notes
. We have never squarely considered the interaction of § 1961,
Kaiser, Briggs
and Rule 37(b). Our holding here is consistent with that of the other courts of appeals.
