Mr. Justice Blackmun
announced the judgment of the Court and an opinion in which The Chief Justice, Mr. Justice Powell, and Mr. Justice Rehnquist join.
This case involves the extent of the protection against multiple prosecutions afforded by the Double Jeopardy Clause of the Fifth Amendment, under circumstances in which the defendant opposes the Government’s efforts to try charges under 21 U. S. C. §§ 846 and 848 in one proceeding. It also raises the question whether § 846 is a lesser included offense of § 848. Finally, it requires further explication of the Court’s decision in Iannelli v. United States, 420 U. S. 770 (1975).
I
A. According to evidence presented at trial, petitioner Garland Jeffers was the head of a highly sophisticated narcotics distribution network that operated in Gary, Ind., from January 1972 to March 1974. The “Family,” as the organization was known, originally was formed by Jeffers and five others and was designed to control the local drug traffic in the city of Gary. Petitioner soon became the dominant figure in the organization. He exercised ultimate authority over the substantial revenues derived from the Family’s drug sales, extortionate practices, and robberies. He disbursed funds to pay salaries of Family members, commissions of street workers, and incidental expenditures for items such as apartment rental fees, bail bond fees, and automobiles for certain [140]*140members. Finally, he maintained a strict and ruthless discipline within the group, beating and shooting members on occasion. The Family typically distributed daily between 1,000 and 2,000 capsules of heroin. This resulted in net daily receipts of about $5,000, exclusive of street commissions. According to what the Court of Appeals stated was “an extremely conservative estimate,” 1 petitioner’s personal share from the operations exceeded a million dollars over the two-year period.
On March 18, 1974, a federal grand jury for the Northern District of Indiana returned two indictments against petitioner in connection with his role in the Family’s operations. The first, No. H-CR-74-56, charged petitioner and nine others with an offense under 21 U. S. C. § 846,2 by conspiring to distribute both heroin and cocaine during the period between November 1, 1971, and the date of the indictment, in violation of 21 U. S. C. §841 (a)(1).3 App. 5-11. The indictment specified, among other things, that the conspiracy was to be accomplished by petitioner’s assumption of leadership of the Family organization, by distribution of controlled substances, and by acquisition of substantial sums of money through the distribution of the controlled substances. Id., at 6. The [141]*141second indictment, No. H-CR-74-57, charged petitioner alone with a violation of 21 U. S. C. § 848, which prohibits conducting a continuing criminal enterprise to violate the drug laws.4 Like the first, or conspiracy, indictment, this second indictment charged that petitioner had distributed and possessed with intent to distribute both heroin and cocaine, in violation of §841 (a)(1), again between November 1, 1971, and the date of the indictment. As required by the statute, the indictment alleged that petitioner had undertaken the distribution “in concert with five or more other people with respect to whom he occupied a position of organizer, supervisor and [142]*142manager,” and that as a result of the distribution and other activity he had obtained substantial income. App. 3-4.
Shortly after the indictments were returned, the Government filed a motion for trial together, requesting that the continuing-criminal-enterprise charge be tried with the general conspiracy charges against petitioner and his nine codefend-ants. Id., at 12-14. The motion alleged that joinder would be proper under Fed. Rule Crim. Proc. 8, since the offenses charged were of the same or similar character and they were based on the same acts or transactions constituting parts of a common scheme or plan. It also represented that much of the evidence planned for the § 848 trial was based on the same transactions as those involved in the § 846 case. Consequently, it argued that joinder was appropriate and within the court’s power pursuant to Fed. Rule Crim. Proc. 13.
The defendants in the § 846 case filed a joint objection to the Government’s motion. App. 16-24. Petitioner and his nine codefendants argued generally that joinder would be improper under Fed. Rules Crim. Proc. 8 and 14, since neither the parties nor the charges were the same. The codefendants were particularly concerned about the probable effect of the evidence that would be introduced to support the continuing-criminal-enterprise charge and about the jury’s ability to avoid confusing the two cases. Another argument in the objection focused directly on petitioner.5 It noted that the § 846 indict[143]*143ment charged 17 overt acts, but that petitioner was named in only 10 of them, and was alleged to have participated actively in only 9. Thus, the argument went, it was likely that much of the evidence in the conspiracy trial would not inculpate petitioner and would therefore be inadmissible against him in the continuing-criminal-enterprise trial. Although a severance of the conspiracy charges against petitioner from those against the nine codefendants might have alleviated this problem, petitioner never made such a motion under Rule 14. On May 7, the court denied the Government’s motion for trial together and thereby set the stage for petitioner’s first trial on the conspiracy charges.
B. The trial on the § 846 indictment took place in June 1974. A jury found petitioner and six of his codefendants guilty. Petitioner received the maximum punishment applicable to him under the statute — 15 years in prison, a fine of $25,000, and a 3-year special parole term.6 The Court of Appeals affirmed the conviction, 520 F. 2d 1256 (CA7 1975), and this Court denied certiorari, 423 U. S. 1066 (1976).7
[144]*144While the conspiracy trial and appeal were proceeding, petitioner was filing a series of pretrial motions in the pending criminal-enterprise case. When it appeared that trial was imminent, petitioner filed a motion to dismiss the indictment on the ground that in the conspiracy trial he already had been placed in jeopardy once for the same offense. He argued both that the two indictments arose out of the same transaction, and therefore the second trial should be barred under that theory of double jeopardy, and that the “same evidence” rule of Blockburger v. United States, 284 U. S. 299 (1932), should bar the second prosecution, since a § 846 conspiracy was a lesser included offense of a § 848 continuing criminal enterprise.8 To forestall the Government’s anticipated waiver argument, petitioner asserted that waiver was impossible, since his objection to trying the two counts together was based on his Sixth Amendment right to a fair trial, and his opposition to the § 848 trial was based on his Fifth Amendment double jeopardy right. A finding of waiver, according to his argument, would amount to penalizing the exercise of one constitutional right by denying another. App. 25-27.
The Government, in its response to the motion to dismiss, asserted that §§ 846 and 848 were separate offenses, and for this reason petitioner would not be placed twice in jeopardy by the second trial.9 The District Court agreed with this analysis and denied petitioner’s motion shortly before the second trial began.
[145]*145At the second trial, the jury found petitioner guilty of engaging in a continuing criminal enterprise. Again, he received the maximum sentence for a first offender: life imprisonment and a fine of $100,000. See n. 4, supra. The judgment specified that the prison sentence and the fine were “to run consecutive with sentence imposed in H-CR-74-56 [the conspiracy case].” Record, Doc. 105. Thus, at the conclusion of the second trial, petitioner found himself with a life sentence without possibility of probation, parole, or suspension of sentence, and with fines totaling $125,000.10
On appeal, the conviction and sentence were upheld. 532 F. 2d 1101 (CA7 1976). The Court of Appeals concluded that § 846 was a lesser included offense of § 848, since the continuing-criminal-enterprise statute expressly required proof that the accused had acted in concert with five or more other persons. In the court’s view, this requirement was tantamount to a proof of conspiracy requirement.11 Construing § 848 to require proof of agreement meant that all the elements of the § 846 offense had to be proved for § 848, in addition to the elements of a supervisory position and the obtaining of substantial income or resources;12 thus, §§ 846 [146]*146and 848 satisfied the general test for lesser included offenses. Although the court stated that ordinarily conviction of a lesser included offense would bar a subsequent prosecution for the greater offense, relying on Gavieres v. United States, 220 U. S. 338 (1911); Blockburger v. United States, supra; and Waller v. Florida, 397 U. S. 387 (1970), it read Iannelli v. United States, 420 U. S. 770 (1975), to create a new double jeopardy rule applicable only to complex statutory crimes.
The two statutes at issue in Iannelli were 18 U. S. C. § 371, the general federal conspiracy statute, and 18 U. S. C. § 1955, the statute prohibiting illegal gambling businesses involving five or more persons. Despite language in Iannelli seemingly to the contrary, 420 U. S., at 785 n. 17, the Court of Appeals stated that § 371 is a lesser included offense of § 1955. 532 F. 2d, at 1109. The court attached no significance to the fact that § 1955 contains no requirement of action “in concert.” It believed that Iannelli held that greater and lesser offenses could be punished separately if Congress so intended, and it adopted the same approach to the multiple-prosecution question before it. Finding that Congress, in enacting § 848, was interested in punishing severely those who made a substantial living from drug dealing, and that Congress intended to make § 848 an independent crime, the court concluded that §§ 846 and 848 were not the “same offense” for double jeopardy purposes. It therefore held that the conviction on the first indictment did not bar the prosecution on the second.
In his petition for certiorari, petitioner challenged the Court of Appeals’ reading of Iannelli and suggested again that § 846 was a lesser included offense of § 848. He also contended that the Double Jeopardy Clause was violated by the prosecution on the greater offense after conviction for the lesser. Finally, he argued that he had not waived the double jeopardy [147]*147issue. In addition to these issues, it appears that cumulative fines were imposed on petitioner, which creates a multiple-punishment problem. We granted certiorari. 429 U. S. 815 (1976). We consider first the multiple prosecution, lesser included offense, and waiver points, and then we address the multiple-punishment problem.
II
A. The Government’s principal argument for affirming the judgment of the Court of Appeals is that Iannelli controls this case. Like the conspiracy and gambling statutes at issue in Iannelli, the conspiracy and continuing-criminal-enterprise statutes at issue here, in the Government’s view, create two separate offenses under the “same evidence” test of Block-burger. The Government’s position is premised on its contention that agreement is not an essential element of the § 848 offense, despite the presence in § 848 (b) (2) (A) of the phrase “in concert with.” If five “innocent dupes” each separately acted “in concert with” the ringleader of the continuing criminal enterprise, the Government asserts, the statutory requirement would be satisfied. Brief for United States 23.
If the Government’s position were right, this would be a simple case. In our opinion, however, it is not so easy to transfer the Iannelli result, reached in the context of two other and different statutes, to this case. In Iannelli, the Court specifically noted: “Wharton’s Rule applies only to offenses that require concerted criminal activity, a plurality of criminal agents.” 420 U. S., at 785 (emphasis in original). Elaborating on that point, the Court stated: “The essence of the crime of conspiracy is agreement, ... an element not contained in the statutory definition of the § 1955 offense.” Id., at 785 n. 17. Because of the silence of § 1955 with regard to the necessity of concerted activity, the Court felt constrained to construe the statute to permit the possibility that [148]*148the five persons “involved” in the gambling operation might not be acting together.13 See also Pinkerton v. United States, 328 U. S. 640, 643 (1946).
The same flexibility does not exist with respect to the continuing-criminal-enterprise statute. Section 848 (b) (2) (A) restricts the definition of the crime to a continuing series of violations undertaken by the accused “in concert with five or more other persons.” Clearly, then, a conviction would be impossible unless concerted activity were present. The express “in concert” language in the statutory definition quite plausibly may be read to provide the necessary element of “agreement” found wanting in § 1955. Even if § 848 were read to require individual agreements between the leader of the enterprise and each of the other five necessary participants, enough would be shown to prove a conspiracy. It would be unreasonable to assume that Congress did not mean anything at all when it inserted these critical words in § 848.14 In the [149]*149absence of any indication from the legislative history or elsewhere to the contrary, the far more likely explanation is that Congress intended the word “concert” to have its common meaning of agreement in a design or plan. For the purposes of this case, therefore, we assume, arguendo, that § 848 does [150]*150require proof of an agreement among the persons involved in the continuing criminal enterprise.15 So construed, § 846 is a lesser included offense of § 848, because § 848 requires proof of every fact necessary to show a violation under § 846 as well as proof of several additional elements.16
B. Brown v. Ohio, post, p. 161, decided today, establishes the general rule that the Double Jeopardy Clause prohibits a State or the Federal Government from trying a defendant for a greater offense after it has convicted him of a lesser included offense. Post, at 168-169. What lies at the heart of the Double Jeopardy Clause is the prohibition against multiple prosecutions for “the same offense.” See United States v. Wilson, 420 U. S. 332, 343 (1975). Brown reaffirms the rule that one convicted of the greater offense may not be [151]*151subjected to a second prosecution on the lesser offense, since that would be the equivalent of two trials for “the same offense.” Post, at 168. See In re Nielsen, 131 U. S. 176, 187 (1889). Because two offenses are “the same” for double jeopardy purposes unless each requires proof of an additional fact that the other does not, post, at 168, it follows that the sequence of the two trials for the greater and the lesser offense is immaterial,17 and trial on a greater offense after conviction on a lesser ordinarily is just as objectionable under the Double Jeopardy Clause as the reverse order of proceeding.18 Cf. Waller v. Florida, 397 U. S., at 390. Contrary to the suggestion of the Court of Appeals, Iannelli created no exception to these general jeopardy principles for complex statutory crimes.19
The rule established in Brown, however, does have some exceptions. One commonly recognized exception is when all the events necessary to the greater crime have not taken place at the time the prosecution for the lesser is begun. See Brown v. Ohio, post, at 169 n. 7; Blackledge v. Perry, 417 U. S. 21, 28-29, and n. 7 (1974); Diaz v. United States, 223 U. S. 442 (1912). See also Ashe v. Swenson, 397 U. S. 436, [152]*152453 n. 7 (1970) (Brennan, J., concurring). This exception may also apply when the facts necessary to the greater were not discovered despite the exercise of due diligence before the first trial. Ibid.
If the defendant expressly asks for separate trials on the greater and the lesser offenses, or, in connection with his opposition to trial together, fails to raise the issue that one offense might be a lesser included offense of the other, another exception to the Brown rule emerges. This situation is no different from others in which a defendant enjoys protection under the Double Jeopardy Clause, but for one reason or another retrial is not barred. Thus, for example, in the case of a retrial after a successful appeal from a conviction, the concept of continuing jeopardy on the offense for which the defendant was convicted applies, thereby making retrial on that offense permissible. See Price v. Georgia, 398 U. S. 323 (1970); Green v. United States, 355 U. S. 184 (1957); United States v. Ball, 163 U. S. 662 (1896). In a slightly different context, the defendant’s right to have the need for a retrial measured by the strict “manifest necessity” standard of United States v. Perez, 9 Wheat. 579 (1824), does not exist if the mistrial was granted at the defendant’s request. United States v. Dinitz, 424 U. S. 600 (1976). Both the trial after the appeal and the trial after the mistrial are, in a sense, a second prosecution for the same offense, but, in both situations, the policy behind the Double Jeopardy Clause does not require prohibition of the second trial. Similarly, although a defendant is normally entitled to have charges on a greater and a lesser offense resolved in one proceeding, there is no violation of the Double Jeopardy Clause when he elects to have the two offenses tried separately and persuades the trial court to honor his election.20
[153]*153C. In this case, trial together of the conspiracy and continuing-criminal-enterprise charges could have taken place without undue prejudice to petitioner’s Sixth Amendment right to a fair trial.21 If the two charges had been tried in One proceeding, it appears that petitioner would have been entitled to a lesser-included-offense instruction. See Fed. Rule Crim. Proc. 31 (c); Keeble v. United States, 412 U. S. 205 (1973); cf. Sansone v. United States, 380 U. S. 343, 349-350 [154]*154(1965). If such an instruction had been denied on the ground that § 846 was not a lesser included offense of § 848, petitioner could have preserved his point by proper objection. Nevertheless, petitioner did not adopt that course. Instead, he was solely responsible for the successive prosecutions for the conspiracy offense and the continuing-criminal-enterprise offense.22 Under the circumstances, we hold that his action deprived him of any right that he might have had against consecutive trials. It follows, therefore, that the Government was entitled to prosecute petitioner for the § 848 offense, and the only issue remaining is that of cumulative punishments upon such prosecution and conviction.
Ill
Although both parties, throughout the proceedings, appear to have assumed that no cumulative-punishment problem is present in this case,23 the imposition of the separate fines [155]*155seems squarely to contradict that assumption.24 Fines, of course, are treated in the same way as prison sentences for purposes of double jeopardy and multiple-punishment analysis. See North Carolina v. Pearce, 395 U. S. 711, 718 n. 12 (1969). In this case, since petitioner received the maximum fine applicable to him under § 848, it is necessary to decide whether cumulative punishments are permissible for violations of §§ 846 and 848.
The critical inquiry is whether Congress intended to punish each statutory violation separately. See, e. g., Prince v. United States, 352 U. S. 322, 327 (1957); Callanan v. United States, 364 U. S. 587, 594 (1961); Milanovich v. United States, 365 U. S. 551, 554 (1961). Cf. Bell v. United States, 349 U. S. 81, 82 (1955). In Iannelli v. United States, the Court concluded that Congress did intend to punish violations of § 1955 separately from § 371 conspiracy violations. Since the two offenses were different, there was no need to go further. See 420 U. S., at 785-786, nn. 17-18. See also Gore v. United States, 357 U. S. 386 (1958). If some possibility exists that the two statutory offenses are the “same offense” for double jeopardy purposes, however, it is necessary to examine the problem closely, in order to avoid constitutional multiple-punishment difficulties. See North Carolina v. Pearce, 395 U. S., at 717; United States v. Wilson, 420 U. S., at 343.25
As petitioner concedes, Reply Brief for Petitioner 3, the first issue to be considered is whether Congress intended to allow cumulative punishment for violations of §§ 846 and 848. We have concluded that it did not, and this again makes it unnecessary to reach the lesser-included-offense issue.
[156]*156Section 848 itself reflects a comprehensive penalty structure that leaves little opportunity for pyramiding of penalties from other sections of the Comprehensive Drug Abuse Prevention' and Control Act of 1970. Even for a first offender, the statute authorizes a maximum prison sentence of life, a fine of $100,000, and a forfeiture of all profits obtained in the enterprise and of any interest in, claim against, or property or contractual rights of any kind affording a source of influence •over, the enterprise. §§ 848 (a)(1), (2). The statute forbids suspension of the imposition or execution of any sentence imposed, the granting of probation, and eligibility for parole. § 848 (c). In addition, § 848 is the only section in the statutes controlling drug abuse that provides for a mandatory minimum sentence. For a first offender, that minimum is 10 years.
§ 848 (a)(1). A second or subsequent offender must receive a minimum sentence of 20 years, and he is subject to a fine of up to $200,000, as well as the forfeiture described above and the maximum of lifetime imprisonment. Ibid. Since every § 848 violation by definition also will involve a series of other felony violations of the Act, see §§ 848 (b)(1), (2), there would have been no point in specifying maximum fines for the § 848 violation if cumulative punishment was to be permitted.
The legislative history of § 848 is inconclusive on the question of cumulative punishment.26 The policy reasons usually offered to justify separate punishment of conspiracies and [157]*157underlying substantive offenses, however, are inapplicable to §§ 846 and 848. In Callanan v. United States, 364 U. S., at 693-594, the Court summarized these reasons:
“[Collective criminal agreement — partnership in crime— presents a greater potential threat to the public than individual delicts. Concerted action both increases the likelihood that the criminal object will be successfully attained and decreases the probability that the individuals involved will depart from their path of criminality. Group association for criminal purposes often, if not normally, makes possible the attainment of ends more complex than those which one criminal could accomplish. Nor is the danger of a conspiratorial group limited to the particular end toward which it has embarked. Combination in crime makes more likely the commission of crimes unrelated to the original purpose for which the group was formed. In sum, the danger which a conspiracy generates is not confined to the substantive offense which is the immediate aim of the enterprise.”
Accord, Iannelli v. United States, 420 U. S., at 778.
As this discussion makes clear, the reason for separate penalties for conspiracies lies in the additional dangers posed by concerted activity. Section 848, however, already expressly prohibits this kind of conduct. Thus, there is little legislative need to further this admittedly important interest by authorizing consecutive penalties from the conspiracy statute.
Our conclusion that Congress did not intend to impose cumulative penalties under §§ 846 and 848 is of minor significance in this particular case. Since the Government had the right to try petitioner on the § 848 indictment, the court had the power to sentence him to whatever penalty was authorized by that statute. It had no power, however, to impose on him a fine greater than the maximum permitted by § 848. Thus, if petitioner received a total of $125,000 in fines [158]*158on the two convictions, as the record indicates, he is entitled to have the fine imposed at the second trial reduced so that the two fines together do not exceed $100,000.
The judgment of the Court of Appeals, accordingly, is affirmed in part and vacated in part, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
