In this appeal, we have occasion to consider the effect of jury verdicts acquitting one alleged conspirator and convicting the sole other alleged conspirator on the same count in the same trial. Specifically, the convicted conspirator argues that the "rule of consistency"--a traditionally recognized exception to the general principle proclaimed in Dunn v. United States, 284 U.S. 390, 393-394, 52 S. Ct. 189, 190-191, 76 L. Ed. 356 (1932), that inconsistency in a criminal verdict does not require setting the verdict aside--invalidates his conviction. The defendant relies in large part on our approach in United States v. Bosch Morales, 677 F.2d 1, 3 (1st Cir.1982), wherein we acknowledged the rule of consistency while recognizing a similar exception to the Dunn rule. In light of the reasoning of United States v. Powell, 469 U.S. 57, 105 S. Ct. 471, 83 L. Ed. 2d 461 (1984), however, we conclude that the rule of consistency embraced by Bosch Morales is no longer viable. We therefore affirm the judgment.

A five-count indictment charged appellant George Bucuvalas, along with Aristides Poravas and Christie Venios, with attempted bribery under 18 U.S.C. Sec. 201(b)(1) and with conspiracy to commit bribery under 18 U.S.C. Sec. 371. The indictment alleged three separate deals with an undercover agent of the Internal Revenue Service. In the first deal, Bucuvalas allegedly paid cash in exchange for corrupt tax assistance. Then, in separate bribery schemes, he allegedly conspired first with Poravas, and then with Venios, to resolve the tax problems of those two individuals in the same manner. Accordingly, Count One charged Bucuvalas alone with bribery. Count Two charged Bucuvalas and Poravas with conspiracy, and Count Three charged both with the substantive bribery offense. In turn, Count Four charged Bucuvalas and Venios with conspiracy, and Count Five charged both with the underlying bribery.

The jury found Poravas guilty on both Counts Two and Three, and Venios not guilty on both Counts Four and Five. Yet it found Bucuvalas guilty only on Counts Three and Four--i.e., of the substantive bribery offense in connection with the Poravas deal, and of conspiracy in connection with the Venios deal. Bucuvalas appeals, arguing that because his alleged co-conspirator Venios was acquitted, his conviction on the conspiracy charge must be set aside.

The crime of conspiracy by definition involves an agreement between two or more persons to commit a criminal offense. See, e.g., Rogers v. United States, 340 U.S. 367, 375, 71 S. Ct. 438, 443, 95 L. Ed. 344 (1951); 18 U.S.C. Sec. 371 ("If two or more persons conspire...."). The parties have stipulated for the purpose of this appeal (1) that there was sufficient evidence for a reasonable jury to convict Bucuvalas of conspiracy under Count Four, and (2) that there was not sufficient evidence for a reasonable jury to have found in Count Four that Bucuvalas conspired with anyone other than Venios.1 In light of the parties' stipulations, the sole issue before us is whether the rule of consistency mandates Bucuvalas' acquittal on Count Four solely because his conviction was logically inconsistent with the acquittal of his sole alleged co-conspirator.2

The underlying rationale of the rule of consistency is that "the acquittal of all but one potential conspirator negates the possibility of an agreement between the sole remaining defendant and one of those acquitted of the conspiracy and thereby denies, by definition, the existence of any conspiracy at all." United States v. Espinosa-Cerpa, 630 F.2d 328, 331 (5th Cir.1980). This rationale rests on the assumption that an acquittal is necessarily equivalent to a factual determination by the jury that the government failed to prove guilt beyond a reasonable doubt.3 Similarly, in Bosch Morales we overturned a conspiracy conviction where the defendant had been acquitted of all the overt acts charged in support of the conspiracy, reasoning that "acquittal on the substantive counts constitutes a determination that no overt act ... took place." 677 F.2d at 3. Yet in Dunn, and again in Powell, the Court held that no such meaning could be imputed to a jury acquittal.

The petitioner in Dunn was convicted of maintaining a nuisance by keeping intoxicating liquor for sale at a specified place. He was acquitted, however, of additional counts charging unlawful possession and unlawful sale of such liquor. On appeal, he argued that his conviction on the nuisance charge was inconsistent with his acquittal on the other counts, and must therefore be reversed. The Court rejected this argument, holding that "[c]onsistency in the verdict is not necessary." 284 U.S. at 393, 52 S.Ct. at 190. The Court recognized that "the verdict may have been the result of compromise, or of a mistake," id. at 394, 52 S.Ct. at 191, but declined to upset the verdict by speculation into the matter. It therefore affirmed Dunn's conviction, stating:

The most that can be said in such cases is that the verdict shows that either in the acquittal or the conviction the jury did not speak their real conclusions, but that does not show that they were not convinced of the defendant's guilt. We interpret the acquittal as no more than their assumption of a power which they had no right to exercise, but to which they were disposed through lenity.

Id. (quoting Steckler v. United States, 7 F.2d 59, 60 (2d Cir.1925) (emphasis added)).

In Powell, the Court unanimously reaffirmed the Dunn rule. The petitioner in Powell was convicted under 21 U.S.C. Sec. 843(b) of "facilitat[ing]" certain felonies--conspiracy to possess with intent to distribute cocaine and possession with intent to distribute cocaine--but was acquitted of those same underlying offenses. Assuming such verdicts to be inconsistent, the Court nonetheless upheld the convictions. The Court disapproved several recent cases, including our Bosch Morales decision, that had "begun to carve exceptions out of the Dunn rule," id. at 63, 105 S.Ct. at 475, saying that "[t]he rule established in Dunn ... has stood without exception in this Court for 53 years.... [W]e think it should [remain that way]." Id. at 69, 105 S.Ct. at 479. It held that, in the face of inconsistent verdicts, one cannot "necessarily assume[ ] that the acquittal ... was proper--the one the jury 'really meant.' " Id. at 68, 105 S.Ct. at 478. "It is equally possible that the jury, convinced of guilt, properly reached its conclusion on [one] offense, and then through mistake, compromise, or lenity, arrived at an inconsistent conclusion on the [other] offense." Id. at 65, 105 S.Ct. at 476.

The Court noted that the prerogative to reach inconsistent verdicts through compromise or leniency, while technically unlawful, has been recognized as consonant with the jury's "historic function, in criminal trials, as a check against arbitrary or oppressive exercises of power by the Executive Branch." 469 U.S. at 65, 105 S. Ct. at 476. It rejected as unworkable and unwise a rule that would allow criminal defendants to challenge inconsistent verdicts on the ground that in their cases mistake rather than leniency had been the cause. The Court indicated that independent review of the sufficiency of the evidence by the trial and appellate courts affords adequate protection against "jury irrationality." 469 U.S. at 67, 105 S.Ct. at 478.

Neither Dunn nor Powell, of course, involved inconsistent verdicts between two alleged co-conspirators.4 Yet in the wake of the Powell decision, the continuing vitality of the rule of consistency has been sharply questioned, because the acquittal of all conspirators but one does not, under Powell, necessarily indicate that the jury found no agreement to act. Two circuits explicitly have abandoned the rule. United States v. Andrews, 850 F.2d 1557, 1560-62 (11th Cir.1988) (en banc) (overruling Herman v. United States, 289 F.2d 362 (5th Cir.1961)), cert. denied, --- U.S. ----, 109 S. Ct. 842, 102 L. Ed. 2d 974 (1989); United States v. Valles-Valencia, 823 F.2d 381, 382 (9th Cir.1987), modifying 811 F.2d 1232 (overruling Lubin v. United States, 313 F.2d 419 (9th Cir.1963)).5 And many others have, in dictum, expressed doubts as to the rule's current validity. See, e.g., United States v. Dakins, 872 F.2d 1061, 1065 (D.C.Cir.) (Powell "cast[s] doubt" upon rule), cert. denied, --- U.S. ----, 110 S. Ct. 410, 107 L. Ed. 2d 375 (1989); United States v. Garcia, 882 F.2d 699, 704-05 (2d Cir.) (quoting Andrews favorably), cert. denied, --- U.S. ----, 110 S. Ct. 348, 107 L. Ed. 2d 336 (1989); Government of the Virgin Islands v. Hoheb, 777 F.2d 138, 142 n. 6 (3d Cir.1985) (rule "may be a vestige of the past"); United States v. Villasenor, 894 F.2d 1422, 1428 n. 6 (5th Cir.1990) ("of highly questionable validity")6; United States v. Mancari, 875 F.2d 103, 104 (7th Cir.1989) (Valles-Valencia decision "makes good sense"). See also Note, The Unnecessary Rule of Consistency in Conspiracy Trials, 135 U.Pa.L.Rev. 223 (1986).

The sole divergent view appears in United States v. Suntar Roofing, Inc., 897 F.2d 469 (10th Cir.1990). The district court had rejected the rule in light of Powell and the Andrews and Valles-Valencia decisions. 709 F. Supp. 1526, 1530-34 (D.Kan.1989). The Tenth Circuit, while affirming the convictions due to the existence of unindicted co-conspirators,7 implied that, in its view, the rule may have continuing vitality: "Unfortunately, the trial court's conclusion is substantially undercut by the fact that the Powell opinion does not discuss Hartzel [v. United States, 322 U.S. 680, 64 S. Ct. 1233, 88 L. Ed. 1534 (1944) ] or expressly overturn the traditionally recognized exception." 897 F.2d at 475.

Yet the Hartzel decision to which the Tenth Circuit referred did not involve inconsistent jury verdicts. Instead, the "only co-conspirators of petitioner named in the indictment" had their convictions set aside by judges due to insufficient evidence. 322 U.S. at 682 n. 3, 64 S. Ct. at 1234 n. 3. It has been, and remains, the law that where the evidence against all of an individual's alleged co-conspirators is deemed legally insufficient, the evidence against that individual is by definition also insufficient. See, e.g., Morrison v. California, 291 U.S. 82, 93, 54 S. Ct. 281, 286, 78 L. Ed. 664 (1934); Gebardi v. United States, 287 U.S. 112, 116, 123, 53 S. Ct. 35, 36, 38, 77 L. Ed. 206 (1932); United States v. Velasquez, 885 F.2d 1076, 1090-1091 and n. 13 (3d Cir.1989) (expressly noting it was not applying the rule of consistency, court held that an earlier appellate finding of insufficient evidence to convict the only alleged co-conspirator required finding insufficient evidence as to the remaining defendant.); United States v. Levario, 877 F.2d 1483, 1486 (10th Cir.1989) (trial court's granting motion for judgment of acquittal as to only alleged co-conspirator precluded conspiracy conviction); United States v. Hernandez-Palacios, 838 F.2d 1346, 1348-49 (5th Cir.1988) (same). A court's determination that there is insufficient evidence to convict cannot be equated with a jury's determination that a defendant, for whatever reason, should be acquitted. Accordingly, rather than there being any "conflict between Powell and Hartzel," Suntar Roofing, 897 F.2d at 475-476, the Court's emphasis in Powell on the sufficiency of the evidence fully embraces the Hartzel ruling. See Andrews, 850 F.2d at 1562 n. 15.

The defendant has made no mention of this case law. He contends that conspiracy is different from other offenses because the acquittal of his sole alleged co-conspirator necessarily means that the government has not proved an essential element of its case. But Powell teaches that a jury's verdict of not guilty "is not the same thing as a finding of insufficient evidence to allow a conviction." Andrews, 850 F.2d at 1563 n. 15. Moreover, an apparent failure to prove an essential element of the offense would not distinguish conspiracy from any other case involving an inconsistent verdict. In Dunn, for example, an essential element of the offense of nuisance for which Dunn was convicted was the possession for sale of alcohol; yet he was acquitted of both possession and sale of alcohol. By the same reasoning Bucuvalas applies, it would seem that the government also failed to prove an essential element of the offense for which Dunn was convicted.

Bucuvalas also attempts to distinguish Powell and Dunn on the basis that each involved inconsistent verdicts on separate charges against a single defendant. Yet the Court's reasoning "applies with undiminished force to a case in which the jury has treated codefendants inconsistently." Mancari, 875 F.2d at 104. "[A]fter Powell there can be no presumption that the jury acquitted [one co-conspirator] because the government had failed to prove him guilty beyond a reasonable doubt, and convicted [the other co-conspirator] lawlessly." Id. (emphasis in original). Cf. Harris v. Rivera, 454 U.S. 339, 345, 102 S. Ct. 460, 464, 70 L. Ed. 2d 530 (1981) (per curiam); Standefer v. United States, 447 U.S. 10, 25, 100 S. Ct. 1999, 2008, 64 L. Ed. 2d 689 (1980); United States v. Dotterweich, 320 U.S. 277, 279, 64 S. Ct. 134, 135, 88 L. Ed. 48 (1943). Powell holds that inconsistent verdicts, whether the result of leniency, compromise, or mistake, "should not be reviewable." 469 U.S. at 66, 105 S.Ct. at 477 (footnote omitted).8

We therefore hold that the "rule of consistency" exception to the Dunn rule is no longer viable in light of Powell. As the Supreme Court has indicated in similar circumstances, we do not by so holding "deviate from the sound teaching that 'justice must satisfy the appearance of justice.' " Standefer, 447 U.S. at 25, 100 S.Ct. at 2008 (quoting Offutt v. United States, 348 U.S. 11, 14, 75 S. Ct. 11, 13, 99 L. Ed. 11 (1954)). But Powell instructs that the appearance of justice is satisfied by a reviewing court's finding that the evidence was sufficient to support the jury's decision. 469 U.S. at 67, 105 S. Ct. at 478. As the defendant has stipulated that the evidence was sufficient to support his conspiracy conviction, the judgment is affirmed.9
