Alberto Alaniz, Jr. appeals the district court’s denial of his motion under 28 U.S.C. § 2255 (1994 & Supp. V 1999) to vacate, set aside, or correct his sentence. We reverse because the district court erroneously deemed unreviewable a reviewable issue presented in Alaniz’s § 2255 motion.
I.
In 1997, a jury found Alaniz guilty of conspiring to possess marijuana with intent to distribute, in violation of 21 U.S.C. § 846 (1994), and distributing marijuana, in violation of 21 U.S.C. § 841 (1994). Because Alaniz was convicted years before the Supreme Court decided
Apprendi v. New Jersey,
It is undisputed that the amount of marijuana involved in the distribution count was less than 50 kilograms, and because Alaniz had a prior felony drug conviction, his statutory penalty range was 0-10 years in prison. See 21 U.S.C. § 841(b)(1)(D) (1994). The district court’s key determination — to which Alaniz’s lawyer did not object — was the statutory penalty range for the conspiracy count, which carried higher penalties because it involved more marijuana than the distribution count.
*367 The district court applied the statutory penalty range applicable to an offense, committed by a person with a prior felony drug conviction, involving 1000 kilograms or more of marijuana: 20 years to life in prison. See 21 U.S.C. § 841(b)(l)(A)(vn) (1994). The court held Alaniz responsible for a total of 1149.4 kilograms of marijuana by aggregating two different drug types. The amount of marijuana involved in the conspiracy was 809.2 kilograms. To this amount, the court added 12 ounces of methamphetamine Alaniz sold during the conspiracy period, which the court converted to its marijuana equivalent of 340.2 kilograms using the drug equivalency table in Section 2D1.1 of the U.S. Sentencing Guidelines Manual. If the district court had not included the methamphetamine, Alaniz’s statutory penalty range would have been 10 years to life in prison. See 21 U.S.C. § 841(b)(l)(B)(vii) (1994).
Without the 20-year statutory minimum prison term on the conspiracy count, Alan-iz’s Guidelines imprisonment range would have been 210-262 months. Because the district court applied the 20-year statutory minimum, however, his effective Guidelines imprisonment range was 240-262 months. The court sentenced Alaniz to concurrent terms of 20 years in prison on the conspiracy count and 10 years in prison on the distribution count.
Alaniz appealed, but his lawyer did not challenge the district court’s aggregation of the marijuana and the methamphetamine in setting the statutory penalty range for the conspiracy count. This court affirmed.
See United States v. Alaniz,
Alaniz then filed this § 2255 motion. He raised several claims, only one of which is relevant to this appeal. Alaniz claimed that the lawyer who represented him at trial and on appeal was ineffective for failing to challenge the application of the 20-year statutory minimum on the conspiracy count because the law does not allow the aggregation of a second, uncharged drug type when determining the statutory penalty range. The district court rejected this claim without a hearing, saying: “The sentencing guideline range without the mandatory minimum was 210-262 months. Because movant was sentenced to 240 months, a term within the original guideline range, this issue is unreviewable on appeal.” We granted Alaniz a certificate of appealability to review the application of the 20-year statutory minimum.
II.
By failing to raise it on direct appeal, Alaniz procedurally defaulted his claim that the district court improperly aggregated the marijuana and the methamphetamine when determining the statutory penalty range.
See Johnson v. United States,
An ineffective-assistance claim is analyzed under the familiar
Strickland
framework: the movant must show that his lawyer’s performance fell below the minimum standards of professional competence (deficient performance) and that there is a reasonable probability that the result of the proceedings would have been different if his lawyer had performed competently
*368
(prejudice).
See Strickland v. Washington,
Every circuit that has considered the issue has concluded that a second, uncharged drug type cannot be added to the charged drug type in order to trigger a higher statutory penalty range.
See United States v. Santos,
We conclude that he was. An error increasing a defendant’s sentence by as little as six months can be prejudicial within the meaning of
Strickland. See Glover v. United States,
The final inquiry, then, is what sentence the district court would have imposed when originally sentencing Alaniz if it had not mistakenly believed that it was limited to a range of 240-262 months. In denying Alaniz’s § 2255 motion, the district court did not answer this question; the court deemed the aggregation issue unreviewable because Alaniz’s sentence fell within an area of overlap between the correct and incorrect Guidelines ranges. This was error: such an overlap renders a sentencing error unreviewable only if the district court, at the time of sentencing, states unequivocally that it would impose the same sentence with or without the challenged calculation.
See, e.g., United States v. O’Hagan,
Accordingly, we reverse the district court’s denial of Alaniz’s § 2255 motion. On remand, the district court is instructed to determine what sentence it would have imposed when originally sentencing Alaniz if it had been faced with the correct Guidelines imprisonment range of 210-262 months. If the district court determines that it would have imposed a sentence of less than 20 years in prison, the court is instructed to resentence Alaniz to that lesser prison term.
Finally, Alaniz’s pro se motion to discharge his appointed counsel in this appeal, which we previously ordered taken with the case, is hereby denied.
