Petitioner-appellant Frederic W. Ber-thoff appeals from the district court’s order denying his petition for habeas relief pursuant to 28 U.S.C. § 2255. Berthoff was convicted of drug conspiracy and related charges following a jury trial. His sentence was seven times greater than that of the next most culpable co-conspirator, who cooperated with the government and pled guilty. The district court granted. a certificate of appealability (COA)
sua sponte,
asking this Court to consider whether the disparity in sentencing violated Berthoffs right to a jury trial. Later, it added to the COA the issue of whether Berthoffs conviction violated
Apprendi v. New Jersey,
*126 I. BACKGROUND
A. The Criminal Proceedings
Berthoff, the kingpin of a drug ring, was indicted on seventeen felony charges along with five associates. 1 Following a jury trial with co-defendants William Tibolt and Scott Holland, Berthoff was convicted of conspiring to possess marijuana and hashish with intent to distribute, 21 U.S.C. §§ 841, 846 (Count One); possessing hashish with intent to distribute, id. § 841 (Count Two); tax evasion, 26 U.S.C. § 7206(1) (Count Three); money laundering, 18 U.S.C. § 1956(a) (Counts Seven through Fourteen); and witness tampering, 18 U.S.C. § 1512(b)(3) (Count Sixteen). The United States District Court for the District of Massachusetts sentenced Berthoff to twenty-one years’ imprisonment on Counts One and Two; three years’ imprisonment on Count Three; twenty years’ imprisonment on Counts Seven through Fourteen; and ten years’ imprisonment on Count Sixteen, with the sentences on all counts to run concurrently-
Thomas Cimeno, whom the district court characterized as “the individual next to Berthoff most culpable in this conspiracy,” pleaded guilty prior to trial and cooperated with the government.
Berthoff v. United States,
In an unpublished decision, this Court affirmed BerthofPs conviction.
United States v. Berthoff,
No. 94A1719,
B. The Habeas Petition
In April, 1997, Berthoff timely filed a petition for habeas corpus on the ground that he was denied effective assistance of counsel. He contended that his counsel was required to inform him about plea overtures that had been made by the government and about the effect on his sentence of the likely acceptance of responsibility credit, U.S.S.G. § 3E1.1. The district court denied the petition, and Berthoff appealed the denial.
On December 9, 1998, the district court granted a COA that seemingly concerned the constitutionality of the disparity in sentencing between those defendants who plead guilty and those who stand trial. The parties, however, proceeded with the understanding that the issue on appeal was Berthoffs ineffective assistance of counsel claim.
On December 22, 1999, this Court vacated the COA.
Berthoff v. United States,
No. 99-1276,
On April 9, 2001, the district court issued a report in which it answered the Appeals Court’s five questions and concluded that there was no ineffective assistance of counsel.
Berthoff,
Finally, the district court sua sponte granted a COA concerning “whether the conduct of the prosecutor or this Court in this case unduly and unconstitutionally burdened Berthoffs Sixth Amendment right to trial by jury.” Id. at 61. The court decried the widespread practice of fact bargaining, which it defined as “the knowing abandonment by the government of a material fact developed by law enforcement authorities or from a witness expected to testify in order to induce a guilty plea.” Id. at 62 n. 19. Although it acknowledged that there was no evidence that fact bargaining played any role in Berthoffs sentencing, the court nonetheless suggested that a COA was appropriate on general policy-based grounds, maintaining that “ ‘substantial assistance’ and fact bargaining together constitute the single greatest cause of the disparity in sentencing that so burdens the free exercise of the Sixth Amendment.” Id. at 67 n. 30. Citing the 700% difference between Cimeno’s and Berthoffs sentences, inter alia, the district court concluded that Berthoff “has made ‘a substantial showing of a denial of his constitutional right’ to trial by jury such that issuance of a[COA] is appropriate.” Id. at 70 (quoting 28 U.S.C. § 2253(c)(2)).
In December, 2001, Berthoff moved to amend the COA to include the issue of Apprendi’s retroactive application to this case. The district court allowed the motion.
II. DISCUSSION
A. Berthoffs Sixth Amendment Claim
28 U.S.C. § 2253(c)(1) provides, in relevant part, that an appeal may not be taken from a district court’s final order in a § 2255 proceeding without the issuance of a COA. A COA may issue only if the applicant has made a substantial showing of the denial of a constitutional right.
Id.
at § 2253(c)(2). “A habeas petitioner who fails to demonstrate that his claims satisfy the substantial showing standard may not appeal the denial of habeas corpus at all.”
Bui v. DiPaolo,
“Habeas review is an extraordinary remedy and will not be allowed to do service for an appeal.”
Reed v. Farley,
In this case, the COA was inappropriately issued because Berthoff procedurally defaulted his Sixth Amendment claim and failed to make a substantial showing that his right to a jury trial was denied. He did not raise that issue at any stage of the proceedings below: neither at trial, nor on direct appeal from his convictions, nor in his § 2255 petition. 3 Rather, the district court issued a COA on the Sixth Amendment issue sua sponte, in the absence of briefing or a hearing.
Moreover, the district court’s discussion focused on the constitutional infirmities involved in fact bargaining and inappropriately mechanistic downward departures for substantial assistance.
Berthoff,
[I]n an appropriate case, where the government has engaged in illegal fact bargaining with one defendant, I would not hesitate to hold that a defendant similarly situated in all material respects could take advantage of the fact bargain in order freely to exercise the right to trial by jury guaranteed by the Sixth Amendment.
This is not such a case. After the most thorough reflection, while I fully admit that were I free to do so I would reduce Berthoffs sentence, I can see no principled way to reach such a result and at the same time remain faithful to the judicial decisions that properly control analysis here. The best I can do is grant this certificate of appealability. I respectfully urge the Court of Appeals to address these intractable issues with the aid of the broadest array of amici curiae ...
Id.
at 71 (emphasis added). Under these circumstances, to decide whether fact bargaining violated the Sixth Amendment not only would contravene the procedural default doctrine but would amount to issuing an unlawful advisory opinion.
Cf. United States v. Sabatino,
*129 In sum, this case simply is an inappropriate vehicle for the district court’s concerns. We acknowledge that the district court raises serious and troubling issues regarding sentencing disparity that merit careful consideration in an appropriate case; as the trial court concedes, however, this is not that case. Accordingly, we do not reach the merits of the constitutional issue at this time.
B. Berthoffs Apprendi Claim,
Berthoff contends that his sentence violates Apprendi because the jury did not make findings as to the triggering quantities that would support the 21-year drug trafficking sentence. Under 21 U.S.C. § 841(b)(1)(B), the jury would have had to find that he was responsible for at least one hundred kilograms of a mixture or substance containing a detectable amount of marijuana.
The district court declined to allow Ber-thoff to amend his habeas petition to include the
Apprendi
claim, although it later included it in the COA. We generally review a decision granting or denying a motion to amend a complaint for abuse of discretion.
Watson v. Deaconess Waltham Hosp.,
Berthoff does not argue that the district court abused its discretion in denying his motion to amend. In any event, we will not consider the
Apprendi
claim because the district court correctly held that it lacked the authority to allow the amendment after it had entered judgment on Berthoffs § 2255 petition. “A habeas petitioner may not add new constitutional claims to a petition after the district court has entered judgment.”
Ward v. Whitley,
Affirmed.
Notes
. The factual details of the criminal conspiracy are set forth in
Berthoff
v.
United States,
. On September 25, 2001, this Court denied Berthoff’s request for an expanded COA with request to ineffective assistance of counsel for the reasons stated by the district court. Inef *128 fective assistance of counsel is not an issue in the present appeal.
. Nor does Berthoff make a developed argument as to cause and prejudice or actual innocence on appeal, other than to contend that the sentencing issue was too "novel" to be subject to the procedural default doctrine.
See Reed v. Ross,
. Berthoff contends that the 700% sentencing disparity alone — absent fact bargaining or improper downward departures — violates his Sixth Amendment rights. As set forth supra, this argument is barred by the procedural default doctrine.
