OPINION
Robert Reggie Oleson is a federal prisoner whose motion to amend his pro se § 2255 habeas corpus motion based on the Supreme Court’s recent Apprendi decision was denied because it was mailed one day after the district court dismissed the underlying habeas motion. For the following reasons, the district court did not err in denying Oleson’s motion to amend. Therefore, the denial of Oleson’s motion is AFFIRMED.
I. BACKGROUND
On August 25, 1993, a jury convicted petitioner-appellant, Robert Oleson, of twenty-two counts of drug-related federal crimes. Oleson’s convictions consisted of one count of conspiracy to distribute marijuana under 21 U.S.C. §§ 841 and 846; one count of aiding and abetting the possession of marijuana with the intent to distribute in violation of 21 U.S.C. § 841 and 18 U.S.C. § 2; nineteen counts of interstate travel in aid of racketeering in violation of 18 U.S.C. § 1952; and one count of money laundering in violation of 18 U.S.C. § 1956. Based on these convictions, the district court sentenced Oleson to 300 months imprisonment. Oleson appealed his convictions and sentence. On appeal, we vacated the money laundering conviction, affirmed the remaining convictions, and remanded the case for resen-tencing. United States v. Oleson,
Oleson did challenge his convictions and sentence through alternate routes, however. On January 3, 1996, Oleson filed a § 2255 motion, citing six grounds for habe-as corpus relief. After making little progress, Oleson moved to “withdraw” his ha-beas motion, and on December 11, 1996, the district court dismissed Olesoris § 2255 motion without prejudice.
The voluntary dismissal did not mark the end of Olesoris challenges to his convictions and sentence. On April 18, 1997, Oleson refiled a § 2255 motion for habeas corpus relief. In that motion, he alleged several instances of prosecutorial misconduct and ineffective assistance of counsel. Oleson also claimed that his property was seized in violation of the Fifth Amendment, that his baggage was unconstitutionally searched and seized, that his convictions were not supported by sufficient evidence, and that his money laundering conviction was retroactively misjoined with his other convictions. On September 24, 1999, a magistrate judge issued a Report and Recommendation advising the district court to deny Olesoris habeas motion. On December 3, 1999, Oleson filed objections to the magistrate judge’s order. On Thursday, July 20, 2000, the district court approved the magistrate judge’s order, over Olesoris objections, and denied Ole-soris § 2255 motion.
Approximately a month before the denial of Olesoris habeas motion, on June 26, 2000, the United States Supreme Court decided Apprendi v. New Jersey,
In a motion postmarked Friday, July 21, 2000, and received by the district court on Monday, July 24, 2000, Oleson sought to amend his § 2255 motion to include a challenge to his convictions based on the Ap-prendi decision. Because Olesoris motion to amend was postmarked a day after the denial of his habeas motion, and received four days after the habeas denial, the district court dismissed Oleson’s proposed amendment. Oleson subsequently appealed the district court’s denial of his habeas motion and his motion to amend. This court granted Oleson a certificate of ap-pealability on only one issue: whether the district court erred in denying Olesoris motion to amend. This issue is now before this Court.
II. DISCUSSION
A.
A district court’s denial of a motion to amend a habeas corpus motion is governed by Rule 15 of the Federal Rules of Civil Procedure. See 28 U.S.C. § 2242 113 (explaining that an application for a writ of habeas corpus “may be amended or supplemented as provided in the rules of procedure applicable to civil actions”); Hodges v. Rose,
A party may amend the party’s pleadings once as a matter of course at any*569 time before a responsive pleading is served or, if the pleading is one to which no responsive pleading is permitted and the action has not been placed upon the trial calendar, the party may so amend it at any time within 20 days after it is served. Otherwise a party may amend the party’s pleading only by leave of court or by written consent of the adverse party; and leave of court shall be freely given when justice so requires
FED. R. CIV. P. 15(a) (emphasis added).
As its text makes clear, Rule 15(a) mandates that a court freely grant leave to amend when justice so requires. FED. R. CIV. P. 15(a); Crawford v. Roane,
With these interests-of-justiee concerns in mind, a district court’s denial of a motion to amend is generally reviewed for an abuse of discretion. See Coe,
B.
Here, the district court denied Oleson’s motion to amend because the motion to amend was filed after the district court denied Oleson’s underlying § 2255 motion. Apparently, the district court believed that a Rule 15(a) motion cannot, as a matter of law, be brought after a § 2255 habeas motion is denied. To date, this Circuit has not recognized that principle as a rule of law. Rather, we have emphasized that Rule 15 seeks to ensure that cases are . decided on their merits. See, e.g., Tefft v. Seward,
We need not determine whether the allowance of such an amendment is permissible here because the motion to amend is futile and would be barred even if it were timely. Oleson’s proposed amendment is subject to the § 2255 one-year statute of limitations affirmative defense. See Dunlap v. United States,
Although we evaluated Oleson’s amendment for futility, which is a component of the interests-of-justice analysis, we neither apply nor reject the interests-of-justice approach here. Rather, we affirm the district court’s opinion because both alternatives lead to the same result. If, as a matter of law, it is correct to bar a Rule 15(a) motion to amend after the underlying § 2255 motion is dismissed, then the district court was correct in denying Oleson’s motion to amend. Similarly, if it is correct to apply an interests-of-justice analysis, Oleson’s motion to amend would still be denied due to its futility. Because both alternatives lead to the same result, we affirm the district court’s opinion without deciding the question of whether a Rule 15(a) motion is barred, as a matter of law, once the underlying § 2255 motion is denied. For those reasons, the district court’s order denying Oleson’s motion to amend is AFFIRMED.

. As another basis for futility, four of our sister circuits have held that even initial § 2255 habeas motions seeking to retroactively apply Apprendi are not permitted because Apprendi was not retroactive in its effect. United States v. Sanders,
