Wilsоn Urrego-Linares appeals his convictions and sentences for possession with intent to distribute cocaine and interstate travel in aid of racketeering. 21 U.S.C.A. § 841(a)(1) (West 1981); 18 U.S.C.A. § 1952 (West Supp.1989). Since the offenses were committed after November 1,1987, the sentences were governed by the Sentencing Reform Act of 1984, 18 U.S.C.A. §§ 3551, et seq. (West 1985 & Supp.1989), and the sentencing guidelines promulgated by the United States Sentencing Commission.
Urrego contends that the district court erred in not reducing his guideline sentencing range by 2 levels for acceptance of responsibility. In support of this contention he argues that he was entitled to application of this mitigating factor since the government did not prove by clear and convincing evidence that he was not entitled to it. We reject this contention and hold that a defendant seeking the application of a mitigating factor to a sentencing range determination has the burden of convincing the court of its applicability by a preponderance or greater weight of the evidence.
Urrego also challenges his conviction on the ground that the district court abused its discretion in allowing into evidence statements of a co-conspirator uttered after Urrego’s arrest and after the seizure of the cocaine which was the object of the conspiracy. Finding no error, we affirm.
I.
In February 1988, while traveling by vehicle on Interstate 95 in North Carolina, Urrego and Carlos Restrepo-Garcia were stopped by law enforcement officers. A search of their vehicle uncovered four kilograms of cocaine. After they were arrested, Restrepo agreed to cooperate with the government. He informed authorities that he and Urrego were traveling to New York to sell the cocaine to Wilson Nelson Rivera. At the government’s request he placed monitored telephone calls to Rivera in New York.
During the first conversation Restrepo told Rivera that Urrego had become ill and could not comрlete the trip. This scheme, apparently designed to lure Rivera to North Carolina, was unsuccessful for Rivera advised Restrepo to drive to New York alone if Urrego remained too ill to travel. Also during the telephone conversation Rivera told Restrepo that he had spoken previously with Urrego and had recеived conflicting reports on how many “pieces” Urrego possessed. Following a second telephone conversation Restrepo traveled to New York and met with. Rivera, purportedly for the delivery of the four kilograms of cocaine. At this meeting Rivera was arrested and a card bearing the name of Urregо’s mother was seized from Rivera’s wallet.
At Urrego’s trial the district court allowed Restrepo to testify concerning the substance of his telephone conversations with Rivera. The court ruled that the statements were admissible as those of a co-conspirator under Federal Rule of Evidence 801(d)(2)(E).
II.
The offenses for which Urrego was convicted resulted in an offense level of 30. In addition to correctly stating this, the presentence report recommended that this base offense level be enhanced 2 levels on the basis that Urrego occupied a supervisory role in the criminal activity. Guideline § 3Bl.l(c). Urrego objected to this proposеd increase and also challenged the pre-sentence recommendation that he not be allowed a 2- level reduction for acceptance of responsibility. See Guideline § 3El.l(a). At the sentencing hearing, the district court first determined that a 2-level increase for a supervisory role was not warranted. It then found that Urrego was not entitled to the 2- level reduction for accepting responsibility. Urrego’s resulting offense level of 30 provided for a sentencing *1237 range of 97-121 months and the court sentenced him to 97 months.
Urrego challenges the denial of a 2- level reduction in several respects. He first argues that the district court improperly rеlied on the fact that he refused to implicate his mother in drug trafficking as the basis for denying him the reduction. He also argues that the district court improperly relied on alleged discrepancies between his post-trial statements and the testimony of his co-conspirator Restrepo. In the alternative he contends that he is at least entitled to a resentencing hearing because the record is unclear as to the standard of proof used by the district court in resolving this disputed fact and on whose shoulders the district court placed the ultimate burden. In this regard he erroneously contends that under the Sentencing Guidelines the standard of proof is onе of clear and convincing evidence and that the burden of proof is always on the government, not only to prove the application of an aggravating factor but also to prove that a mitigating factor does not apply.
III.
Guideline § 6A1.3(a) states:
In resolving any reasonable dispute concerning a factor important to the sentencing determination, the court may consider relevant information without regard to its admissibility under the rules of evidence applicable at trial, provided that the information has sufficient indicia of reliability to support its probable accuracy.
The Sentencing Guidelines do not, however, specifically address thе subject of standards of proof or which party should bear the burden. The Sentencing Reform Act is likewise silent on this issue and leaves to the courts the responsibility of fashioning appropriate rules. 1 Unquestionably, the guidelines do not themselves mandate a change in existing law; nor is there good reason to conclude that use of the guidelines to structure sentencing discretion necessitates any change.
A.
Prior to the implementation of sentencing guidelines in the federal system, the Supreme Court stated in
McMillan v. Pennsylvania,
Urrego contends that even if a more rigorous standard is not constitutionally required, this court should nevertheless adopt a clear and convincing standard on fairness grounds. He points out that some courts previously employed a clear and convincing standard,
see United States v. Fatico,
We discern no reason to require application of a standard greater than approved by
McMillan.
The Court there noted that “criminal sentencing takes place only after a defendant has been adjudged guilty beyond a reasonable doubt.”
Indeed, before guideline sentencing a court intuitively fashioned what it considered an appropriate sentence and did so without any obligation to give reasons and many times without ultimate resolution of disputed facts. Fairness to a defendant is substantially increased under guideline sentencing with application of a preponderance of the evidence standard, for if a court is considering applying an aggravating factor which will have the effect of increasing the sentence, the court must afford a defendant the opportunity to oppose and specifically address its application. And, before it may refuse to apply a mitigating factor which a defendant has raised, it must first give the defendant an opportunity to present evidence supporting its application and, if rejeсted, make a specific finding on the record.
B.
Urrego also contends that the government should bear the burden of proof on all issues at sentencing whether they would potentially increase or decrease the sentence.
See Dolan,
Urrego generally relies on pre-guidelines cases to support his claim that the government should be required to bear the burden of proof regarding disputed matters contained in the presentence report.
United States v. Lee,
Here, the guideline in question involved a potential decrease in the offense level which would have had the effect of lowering Urrego’s ultimate sentencing range. 2 In these circumstances, we hold *1239 that the defendant has the burden of establishing by a preponderance of the evidence the applicability of the mitigating factor in question. We therefore reject the position advanced by Urrego and expressed by the district сourt in Dolan.
A defendant’s guilty plea or conviction establishes a base offense level and a corresponding sentencing range. As the Court noted in McMillan, at this stage of the proceedings the defendant’s guilt has already been established beyond a reasonable doubt. If the defendant advances a mitigating factor which, if accepted by the court, would lower the sentencing range and potentially reduce the ultimate sentence, the defendant should bear the burden of proof to establish the mitigating factor(s) by a preponderance. Clark, 1989 U.S. Dist. Lexis 5347 at 4-5. However, if the government seeks to enhance the sentencing range and potentially increase the ultimate sentence, it should bear the burden of proof. Such a scheme is entirely consistent with the directives of the Supreme Court in McMillan and with due process requirements.
Upon conviction a defendant is entitled only to have his sentence correctly determined in accordance with the applicable law and based upon reliable evidеnce.
See Townsend v. Burke,
IV.
Although the court did not announce that it was applying a preponderance of the evidence test, it is clear that Urrego failed to meet this burden. The court carefully weighed the evidence presented on the issue of acceptance of responsibility and concluded that a 2- level reduction was not warranted.
After conviction at the hands of a jury Urrego contended that he immediately contacted the investigating officers and volunteered tо fully cooperate. In his post-trial statement to a probation officer Urrego conceded involvement in cocaine trafficking and apparently offered to testify for the government in subsequent proceedings. However, in the presentence report, the probation officer recommended that Urre-go not be given the 2-level adjustment. This recommendation was evidently determined due to the fact that Urrego had minimized his mother’s role in the operation and because the probation officer felt that Urrego’s statement of the extent of his involvement conflicted with the testimony of the chief government witness.
At the sentenсing hearing the district court found that Urrego was attempting “to minimize his involvement much more than it would seem the evidence indicates.” The court also found that Urrego was “maybe loose with the truth in order to ... gain as much as he can.” Regarding Urre-go’s denial of the extent of his mother’s involvement, the district court concluded that it “could forgive [that] because of his youth and his desire to protect his mother.” Ultimately, the court held that an adjustment was not warranted.
Recently, in
United States v. White,
V.
Urrego’s contention that the district court abused its discretion in admitting the statements of his co-conspirator is likewise without merit. He argues that since he and Restreрo already had been apprehended and the cocaine seized, the statements made by Rivera during the monitored telephone conversations were outside of the course of the conspiracy.
The fact that Urrego and one of his co-conspirators were arrested did not necessarily mean that the conspiracy was terminated.
United States v. Grubb,
AFFIRMED.
Notes
. The Supplementary Report on the Initial Sentencing Guidelines and Policy Statements provides:
With respect to sentencing issues that are genuinely disputed, the Commission chose simply to emphasize the importance of accuracy and fairness. Especially in light of questions that have been raised regarding the Commission’s power to prescribe enforceable rules for dispute resolution, most of the procedural details аre left for resolution by the sentencing court in light of the nature and importance of the particular issue and the context in which it arises. Existing precedent will provide some guidance; more extensive precedent will develop as the issues become more sharply defined in context.
Supplementary Report оn the Initial Sentencing Guidelines and Policy Statements 46-47 (June 18, 1987). The Commission specifically left for court resolution such issues as ”[w]hich party bears the burden of persuasion?” and ”[w]hat is the weight of the burden of persuasion.” Id. at 47 n. 79.
. Without application of acceptance of responsibility, Guideline § 3El.l(a), Urrego's offense level was 30 prоducing a sentencing range of 97-121 months. A 2- level reduction for acceptance of responsibility would have produced a sentencing range of 78-97 months. Had the
*1239
court stated that regardless of how it ultimately resolved the issue regarding acceptance of responsibility the sentence would be 97 months, review of this issue would have been unnecessary.
