Michael Britt appeals from the order of the District Court 1 vаcating his guilty plea. The government moved before sentencing to vacate Britt’s guilty plea after learning that Britt had not complied with the terms of the plea agreement pursuant to which he pled. Specifically, the government alleged that Britt did not disclose the full extent of his drug dealings, plotted with codefendants to conceal drug trafficking activity, and testified untruthfully at the trial of his codefendant Daniel Stevens. After an evidentiary hearing, the District Court, concluding that Britt had materially breached his plea agreеment, granted the government’s motion to set aside Britt’s guilty plea. On appeal, Britt argues: (1) setting aside his guilty plea and charging him with a more serious drug crime violated the Double Jeopardy Clause and principles of contract law applicable to plea agreements; and (2) the District Court relied on improper and unconstitutionally obtained evidence in its decision. 2 We affirm.
I.
Britt was arrested on December 12,1987, while attempting to purchase 150 to 300 pounds of marijuana from a cooperating government informant. He negotiated a plea agreement in which he agreed to plead guilty to one count of conspiracy to distribute and possession with intent to distribute marijuana in violation of 21 U.S.C. §§ 841(a)(1), 846 (1988). In return for the government’s promise to file no additional Title 21 criminal charges, Britt pledged to “fully and completely cooperate with the United States in its investigation into the use, possession, and trafficking of controlled substances and related criminal activity within the Northern District of Iowa and elsewhere.” Appellant’s Appendix at A-l (Initial Plea Agreement at 112). Britt also agreed to forfeit all property gained through or associated with drug trafficking. Id. at A-3 (Initial Plea Agreement at 11 6). The agreement was signed by the parties and their counsel on January 6, 1988, and Britt entered his guilty plea on November 8, 1988.
Over the course of the year, Britt had several debriefing meetings with federal agents, made recorded phone conversations to other suspected drug traffickers, participated in at least one controlled buy in which his seller was аrrested, and testified at the trial of Daniel Stevens. In his interviews with law enforcement agents, Britt repeatedly denied any involvement in a marijuana transaction in Grand Junction, Colorado, a location mentioned by Britt in a tape-recorded conversation made during the attempted sale leading to his arrest. Britt denied having any marijuana dealings with Chris Batten and denied any knowledge of Batten’s marijuana trafficking. Britt repeatedly maintained that the December 12, 1987 transaction was his only marijuana transaction with Stevens and denied any knowledge of marijuana traffick *356 ing by individuals in the state of Mississippi. At Stevens’ trial, Britt testified truthfully regarding Stevens’ involvement in the December 12 transaction but did not reveal his knowledge of Stevens’ previous marijuana dealings.
On November 22, 1988, Britt was interviewed by an agent of the federal Drug Enforcement Administration (DEA) as part of an independent investigation conducted by the DEA. In that interview, Britt admitted for the first time extensive involvement with several other suspected drug traffickers in Mississippi and Louisiana. Britt made these admissions only after thе agent told Britt that another drug dealer had provided the DEA with information concerning Britt’s dealings in Mississippi. On December 12, 1988, Stevens, who was convicted at trial, contacted law enforcement agents and told them that Britt had perjured himself at Stevens’ trial and had repeatedly lied to investigators. Specifically, Stevens stated: (1) Britt and Batten were involved in extensive marijuana dealings; (2) Britt received marijuana from a source in Louisiana and one in the country of Belize; (3) Britt was involved in a marijuana transaction in Grand Junсtion, Colorado; and (4) contrary to his claims, Britt knew an individual named Frank Conrad, a suspected marijuana dealer. Stevens told the agents that he and Britt met on several occasions after their initial arrest and agreed to conceal the extent of their drug dealings. Britt gave Stevens a substantial amount of cash to use to hire an attorney with the implied understanding that in return Stevens would remain quiet.
On December 13, 1988, Britt submitted to a polygraph examination at the government’s request. In the opinion of the examiner, Britt failеd to respond truthfully to questions regarding his drug dealings with Stevens and Batten and the forfeiture of assets. In the interview following the examination, Britt admitted that he might have withheld certain assets but steadfastly maintained that he had been completely truthful regarding his marijuana dealings with Stevens and Batten. On January 12, 1989, Stevens wore a body recorder to Britt’s home and recorded Britt bragging that he had perjured himself at Stevens' trial and had lied to the agents. Britt continued to implore Stevens to conceal the Colorado marijuana transaction.
On December 29, 1988, the government informed Britt that it considered him to have violated his plea agreement and intended to seek additional or alternate charges against him. The government moved to vacate Britt’s plea and, after an evidentiary hearing in June 1989, the District Court found that Britt had materially breached his plea agreement and granted the government’s motion to vacate his guilty plea. The government then filed a second information against Britt charging him with the same count of conspiracy to distributе marijuana as before but this time alleging that the quantity of drug involved was more than fifty kilograms. This changed the maximum penalty to which Britt was subject from five years to between 210 and 262 months in prison. Britt entered a conditional plea of guilty on this count reserving his right to appeal the vacating of his first guilty plea to this Court.
II.
We are presented with the question of whether a defendant’s failure after his guilty plea is entered to fulfill his obligations under his plea agreement releases the government from its bargain and entitles it to bring additional charges against the defendant. Britt argues that setting aside his guilty plea and allowing the government to file a more severe drug charge against him violated the Double Jeopardy Clause. 3 We conclude that in these circumstances the Double Jeopardy Clause does not bar the setting aside of Britt’s guilty plea and the filing of a more serious drug charge against him.
Several federal courts of appeals have approved the setting aside of plea agree
*357
ments and guilty pleas m circumstances similar to those in this case with no suggestion that such action implicates a defendant’s right not to be twice placed in jeopardy.
See, e.g., United States v. Ataya,
The Supreme Court has addressed the double jeopardy implications of vacating a guilty plea and reinstituting the original charges in
Ricketts v. Adamson,
We conclude that here, as in Ricketts, the defendant has waived his double jeopardy defense in the plea agreement he signed. The plea agreement provides in pertinent part:
3. Mr. Britt will provide complete and truthful information to the attorneys and law enforcement officers of thе govern *358 ment, and the federal grand jury conducting this investigation ... Since the United States insists upon Mr. Britt telling the truth and nothing but the truth during this investigation and in the event he should be called as a witness, his failure to provide truthful information will render this agreement void.
5. It is understood that, upon request by the government, Mr. Britt will voluntarily submit to a polygraph examination ... If the totality of circumstances convinces the government that his statement is not complete and truthful, he will be so informed and any and all obligations imposed on the government by this agreement will be rendеred null and void.
12. If he violates the terms of this agreement, any such testimony or other information provided by him at any time to attorneys or law enforcement officers of the government, or the federal grand jury, may and will be used against him. No statements or other information provided by him shall be deemed to be precluded from use against him in the case of his breach of this agreement.
Appellant’s Appendix at A-2, A-3, A-5 (Initial Plea Agreement at Till 3, 5, 12) (emphasis added).
Britt argues that because his plea agreement contains no
status quo ante
provisions expressly reinstating the original drug charges or returning the parties to their original positions, he did not waive his double jeopardy rights. We disagree.
Ricketts
does not stand for the proposition that only those plea agreements with a
status quo ante
provision will be held to waive a defendant’s double jeopardy rights. The waiver in
Ricketts,
in fact, arose out of the “null and void” language that is also present in Britt’s plea agreement.
See Ricketts,
The language of Britt’s plea agreement is clear: If Britt is not completely truthful in the information he gives to law enforcement agents “all obligations imposed on the government by this agreement will be rendered null and void,” Appellant’s Appendix at A-3 (Initial Plea Agreement 11 5), and “any such testimony or other information provided by him at any time ... may and will be used against him.” Id. at A-5 (Initial Plea Agreement at 1112). As the Court in Ricketts suggested, the terms “null and void” can mean only that the government’s obligations — chiefly, not to file additional charges — are dissolved, leaving the government free to bring any charges it chooses. Moreover, the agreement specifically provides that if Britt violates its terms the government may use against him any and all information provided by him to government attorneys or law enforcement officers. We believe the government bargained for more here than did the state in Ricketts; Britt’s breach did not merely reinstate an earlier charge, but rather allowed the government to use Britt’s own admissions against him in filing more severe charges.
In addition, and as an alternative ground for our decision, we believe that analogous to the situation where a mistrial has been declared over the defendant’s objection, the reprosecution of Britt is not precluded if his guilty plea was set aside because of “manifest necessity.”
See Arizona v. Washington,
First, individuals should be spared the emotional and financial hardship of sucсessive prosecutions at the powerful hand of the State. Second, defendants must be protected from the unfairness of a mistrial declaration designed to give the government a second chance to convict when the first is going badly.
*359
Lovinger v. Circuit Court of the 19th Jud. Circuit,
The phrase “manifest necessity” does “not describe a standard that can be applied mechanically or without attention to the particular problem confronting the trial judge.”
Arizona,
For the reasons discussed above, we hold that the Double Jeopardy Clause does not bar the setting aside of Britt’s guilty plea and the filing of more serious charges against him.
III.
Britt argues that the District Court’s decision to vacate his guilty plea violated contract law principles because: (1) Britt relied on the plea agreement; (2) the government waived its right to complain of Britt’s untruthfulness by allowing him to plead guilty and accepting his testimony at Stevens’ trial; and (3) the government’s sole remedy under the plea agreement for Britt’s untruthfulness is to prosecute him for perjury. We disagree with each of these contentions.
At the outset we note that Britt does not directly challenge as clearly erroneous the District Court’s finding that he materially breached his plea agreement, although throughout his brief he emphasizes the extent of his cooperation with the government. The District Court’s finding that Britt materially breaсhed the agreement by withholding information regarding his own and others’ drug trafficking is amply supported by the record and our consideration of Britt’s claims is premised on this finding.
A plea agreement is contractual in nature and generally governed by ordinary contract principles.
United States v. Brown,
It is disingenuous of Britt to argue that he “relied” on the plea agreement in testifying against Stevens, participating in a controlled buy, and making several recorded phone calls to suspected drug traffickers. This is exactly the performance that the agreement contemplated and Britt was fully aware of the government’s expectations when he entered his plea of guilty.
See United States v. Coon,
Britt’s argument that he substantially performed his obligations under the agreement and that the government’s obligations cannot be dissolved because it received considerable benefit from his performance is similarly unpersuasive. First, Britt’s breach of the agreement cannot be considered minor; as the District Court found, Britt repeatedly lied and concealed information regarding large-scale drug trafficking activity. Second, the fact that the government may have benefitted from Britt’s partial performance does not bar the government from moving to vacate his guilty plea on the ground of his material breach of the plea agreement.
Brown,
Britt next claims that the government waived its right to complain of his dishonesty when it allowed him to plead guilty and accepted his testimony in Stevens’ trial when the government already suspected that Britt was not completely truthful in his debriefing sessions with law enforcement agents.
See United States v. Vogt,
Britt contends that the government’s remedy for his untruthful statements is specified by the plea agreement and is limited to prosecution for perjury. In support of this claim, Britt points to the following language:
4. No testimony or other information provided by Mr. Britt to the United States Attorney’s Office or law enforcement officers or the federal grand jury conducting this investigation, pursuant to this agreement, or any information directly or indirectly derived from such testimony or other information, will be used against him in a criminal trial, except in a prosecution for perjury or giving a false statement, provided that Mr. Britt does not violate the terms of this agreement pursuant to whiсh the grant of immunity is being made.
Appellant’s Appendix at A-2 (Plea Agreement at ¶ 4) (emphasis added). We believe that this provision is clear and does not support Britt's position. Britt’s grant of immunity continues only so long as he abides by the terms of the agreement. *361 Once a breach occurs, the plea agreement and the government’s obligations under it are dissolved and the government’s remedy is no longer limited to criminal prosecutions for perjury.
We reject Britt’s contention that contract principles bind the governmеnt to honor its obligations under the initial plea agreement despite his material breach of the agreement.
IV.
Finally, Britt claims that the District Court’s decision to vacate his guilty plea was based on improper and unconstitutionally derived evidence. Specifically, Britt argues that the results of his polygraph examination should not have been admitted and the tape-recorded evidence gathered by Stevens after Britt’s guilty plea violated Britt’s Sixth Amendment right to counsel.
This Court has traditionally held “that polygraph еxamination results should not be admitted absent a stipulation.”
Anderson v. United States,
Britt’s claim that Stevens elicited incriminating statements frоm Britt concerning the drug conspiracy to which Britt pled guilty in violation of Britt’s Sixth Amendment right to counsel is without merit. After the right to counsel has attached with respect to one crime, the government may investigate a defendant without counsel as to “other crimes to which the Sixth Amendment right has not yet attached.”
Maine v. Moulton,
V.
Finding no merit in any of Britt’s claims, we affirm the order of the District Court vacating Britt’s plea agreement and guilty plea.
Notes
. The Honorable Edward J. McManus, United States Senior District Judge for Northern District of Iowa.
. Britt also argues that because the Federal Rules of Criminal Procedure have no specific provision authorizing a district court to grant the government’s motion to vacate a defendant’s guilty plea, the District Court did not have the power to vacate Britt’s guilty plea. We disagree and believe the District Court’s action fell well within its inherent power to protect the integrity of the judicial process.
. We assume for purposes of this discussion that jeopardy attached when Britt’s guilty plea was accepted by the court.
