ROSENBAUM, Circuit Judge:
Efficiency can be a virtue, particularly for a court. But sometimes we can have too much of even a good thing.1 That’s what happened here. In this case, Petitioner-Appellant Michael Frank Burgess filed a 28 U.S.C. § 2255 motion challenging his conviction and sentence. Although the government opposed Burgess’s motion on the merits, the district court instead, and of its own volition, invoked a collateral-action waiver in Burgess’s plea agreement with the government to dismiss one of Burgess’s claims. Today we hold that a court may not do that.
I.
Petitioner-Appellant Michael Frank Burgess pled guilty to conspiracy to commit wire fraud, in violation of 18 U.S.C. § 371, and money laundering, in violation of 18 U.S.C. § 1957. In his plea agreement, among other things, Burgess waived his right to appeal—which included his right to collaterally challenge his conviction and. sentence—except in four limited circumstances, none of which applies to the collateral action that is the subject of this appeal.2 During his change-of-plea hearing, Burgess testified under oath that he fully-understood this waiver of his right to file a collateral action:
THE COURT: .;, [UJnder this plea agreement you’re giving up your right to claim ineffective assistance of your own counsel in regard to representing you with respect to this matter. Do you understand?
BURGESS: Yes, I do.
The' district court accepted Burgess’s guilty plea and ultimately sentenced Burgess to 180 months’ imprisonment.
Burgess'filed a direct appeal, but his counsel filed a motion to withdraw under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), asserting that no arguable appellate issues of merit existed. We agreed, granted his counsel’s motion, and affirmed Burgess’s conviction and sentence.
Burgess then filed a pro se motion to vacate, set aside, or correct his sentence under 28 U.S.C. § 2255. He listed eight grounds for relief. Among them was Claim 5, the subject of this appeal. In Claim 5, Burgess contended that his counsel was ineffective because he failed to file timely objections to the Pre-Sentence Investigation Report (“PSR”) and to object to aspects of it at sentencing. He also alleged that counsel should have presented mitigating evidence at the sentencing hearing to refute the number‘of victims and the loss amount, two factors that resulted in the addition of enhancements that increased Burgess’s guideline range.
The district court ordered the government to “file a response indicating why the relief sought in the motion should not be granted.”. Also in this order, the..court instructed the government to, among other, things,
(1) State whether Petitioner has used any other available federal remedies including any prior post-conviction motions and, if so, whether an evidentiary hearing was accorded to the movant in any federal court;
[[Image here]]
(3) Summarize the results of any direct appellate relief sought by Petitioner to include citation references and copies of appellant and appellee briefs from every appellate proceeding^ ]
(4) Provide a detailed explanation of whether the motion was or was not filed within the one-year limitation period as set forth in 28 U.S.C. § 2255 (Supp. 1996).
(Emphasis omitted), And specifically.with respect to the government’s response to Requirement (3), the district court directed the government to “indicate whether each claim was raised on direct appeal.” If the petitioner did not raise a claim on direct appeal, the district court instructed the government to “indicate whether it waives the defense concerning the failure to raise the claim on direct appeal.” (Citations omitted). Similarly, if the petitioner did raise a -claim on direct appeal, the court required the government to “indicate whether it waives the defense concerning the relitigation of claims that were pfevi-ously raised and disposed of on direct appeal.” (Citation omitted).
In its response, the government invoked no affirmative defenses, despite the district court’s specific inquiry about several in particular. Indeed, the government expressly denied the applicability of the defenses. of procedural default and procedural bar. And it likewise did not assert the defense of timeliness, though.the government indicated that it was investigating whether Burgess timely filed his motion and said it “may request permission to amend its response if [it discovers] that the motion was not timely filed.” Instead of relying on any affirmative defenses, the government argued that on the merits of Burgess’s motion, he was not entitled to relief under § 2255.
After considering the government’s response and Burgess’s reply, the district court denied Burgess’s §.2255.motion. In reaching this conclusion, the court determined that seven of Burgess’s claims lacked merit. But it 'dismissed Claim 5 based solely on the collateral-action waiver in Burgess’s plea agreement and did not consider the merits of the claim. The court did not give the parties notice that it was considering dismissing Claim 5 based on the collateral-action waiver, and it did not ask the government .whether the government, wished to invoke the waiver.
Burgess sought a certificate of appeala-bility, and a judge of this Court granted it as to the following issue:
Whether the district court erred by denying Mr. Burgess’s claim of ineffective assistance, which was based on trial counsel’s failure to object to the loss calculations used to determine Mr. Burgess’s guideline range at sentencing [Claim 5], by sua sponte applying his sentence-appeal waiver?
II.
Whether the district court has the authority, on its own initiative, to invoke a collateral-action waiver from the . § 2255 movant’s plea, agreement and dismiss the movant’s § -2255 motion on that basis3 raises a question of law. See Day v. McDonough, 547 U.S. 198, 126 S.Ct. 1675, 164 L.Ed.2d 376 (2006) (deciding whether, as a matter of law, a district. court has the authority to sua sponte. deny a state prisoner’s 18 U.S.C. § 2254 petition as untimely). We conduct de novo review of questions of law. Pope v. Sec’y, Fla. Dep’t of Corr., 752 F.3d 1254, 1261 (11th Cir. 2014) (citation omitted)..
If a district court does have that authority, we review for abuse of discretion the district court’s decision to exercise it. Cf. Day, 547 U.S. at 199, 200, 126 S.Ct. 1675 (reviewing for abuse of discretion the district court’s sua sponte application of the Antiterrorism and Effective Death Penalty Act of 1996’s (“AEDPA”) statute of limitations to dismiss a state prisoner’s § 2254 motion).
III.
We begin by considering whether a district court has the authority in resolving a § 2255 motion to raise in the first instance a plea agreement’s collateral-action waiver. Two competing lines of legal reasoning— the rules applying to civil cases, on the one hand, and those applying to certain aspects of collateral-review cases (the “Day line of cases”), on the other—seem to point to different answers to our question. We examine both lines of reasoning.
A. The Rules Applying to Civil Cases
We have previously concluded that a § 2255 motion’s “nature [is that of] a civil matter.” Brown v. United States, 748 F.3d 1045, 1065 (11th Cir. 2014).4 The Federal Rules of Civil Procedure “govern the procedure in all civil actions and proceedings in the United States district courts,” Fed. R. Civ. P. 1, “to the extent that the practice in [§ 2255] proceedings ... is not specified in a federal statute ... or the Rules Governing Section 2255 Cases [ (“§ 2255 Rules” or “§ 2255 R.”) ],” Fed. R. Civ. P. 81(a)(4)(A). Similarly, § 2255 Rule 12 expressly authorizes application of the Federal Rules of CM Procedure to a § 2255 proceeding “to the extent that they are not inconsistent with any statutory provisions or [the § 2255 Rules].”5
So we turn to the § 2255 Rules to ascertain whether they answer our question about whether the district court may, on its.own initiative, invoke the collateral-action waiver from a plea agreement to dismiss a case. Rule 5(b), § 2255 R., sets forth the requirements for any response the government might file to a § 2255 motion. It requires the government to “address the allegations in the motion” and to “state whether the moving party has used any other federal remedies, including any prior post-conviction motions under these rules or any previous rules, and whether the moving party received an evidentiary hearing.” § 2255 R. 5(b). The § 2255 Rules say nothing further about the government’s response to a § 2255 motion or about the district court’s role in raising affirmative defenses.
We therefore look to the Federal Rules of Civil Procedure to see whether they fill the gap. Rule 8(c) governs the pleading of affirmative defenses such as a collateral-action waiver. It requires a party to “affirmatively state any avoidance or affirmative defense, including ... waiver.” Fed. R. Civ. P. 8(c). If a party fails in its answer or amended answer to assert an affirmative defense identified in Rule 8(c), the party forfeits the defense. Fed. R. Civ. P. 12(b), 15(a); see also Day, 547 U.S. at 207-08, 126 S.Ct. 1675 (citing Fed. R. Civ. P. 8(c), 12(b), 15(a)); Jackson v. Seaboard Coast Line R. Co., 678 F.2d 992, 1012 (11th Cir. 1982). And we have recognized that “courts generally lack the ability to raise an affirmative defense sua sponte.” Latimer v. Roaring Toyz, Inc., 601 F.3d 1224, 1239 (11th Cir. 2010) (citation, quotation marks, and alteration omitted). That’s because “the principle of party presentation [is] basic to our adversary system,” Wood v. Milyard, 566 U.S. 463, 472, 132 S.Ct. 1826, 1833, 182 L.Ed.2d 733 (2012), and the court’s invocation of a party’s affirmative defense generally conflicts with that ideal.
We see nothing rendering the requirements of Rules 8(c), 12(b), and 15(a), “inconsistent with any statutory provisions or [the § 2255 Rules].” While the Civil Rules impose requirements on the government’s answer beyond those set forth in the § 2255 Rules, nothing about the additional requirements is at odds with the § 2255 Rules. Applying the Civil Rules, the government’s response to a § 2255 motion must expressly invoke a collateral-action waiver. Otherwise, the government may be deemed to have forfeited that defense.
As a result, if the line of legal reasoning governing civil cases applies here, then the government may have forfeited its collateral-action-waiver defense by failing to include it in its response to Burgess’s § 2255 motion. Relying on this reasoning, Burgess asserts that the district court erred in raising the collateral-action waiver on its own initiative and then dismissing Claim 5 on that basis.
B. The Day Line of Cases
But then there’s the Day line of cases to consider. Despite the fact that we have described § 2255 motions as civil in nature, collateral-review cases such as those involving § 2255 motions have their own peculiarities that render them different in some ways from pure civil proceedings. The Supreme Court delved into these differences and their procedural consequences in Day.
Day involved a habeas petition filed in federal court under 18 U.S.C. § 2254. 547 U.S. at 201,126 S.Ct. 1675. AEDPA imposes a one-year limitation period for the filing of a federal habeas petition under § 2254, id. (citing 28 U.S.C. § 2244(d)(1)(A)), and Rule 5(b), Rules Gov'erning § 2254 Cases (“§ 2254 Rules” or “§ 2254 R.”), requires the state in responding to a § 2254 petition to, among other things, “state whether any claim in the petition is barred by ... a statute of limitations.” Heeding this requirement, the state filed its answer to Day’s petition and expressly agreed that his petition was timely because it had been “filed after 352 days of untolled time.” Day, 547 U.S. at 201, 126 S.Ct. 1675.
In fact, however, the state had made a mathematical error, and Day had filed his petition after 388 days—beyond the 365-day statutory period. Id. at 201-02, 126 S.Ct. 1675. The magistrate judge noticed the error and gave Day an opportunity to show cause why the petition should not be dismissed as untimely. Id. at 202, 126 S.Ct. 1675. When the magistrate judge found Day’s response inadequate, the magistrate judge recommended dismissal of Day’s petition. Id. The district court adopted the magistrate judge’s recommendation and dismissed the case. Id.
On review, the Supreme Court considered “whether a federal court lacks authority, on its own initiative, to dismiss a habeas petition as untimely, once the State has answered the petition without contesting its timeliness.” Id. The Court concluded that under the circumstances in Day’s case, “the federal court had discretion to correct the State’s error and, accordingly, to dismiss the petition as untimely under AEDPA’s one-year limitation.” Yet the Court was careful to note that a district court would abuse its discretion if it “ov-err[o]de a State’s deliberate waiver of a limitations defense.” Id.
The Supreme Court rested its ruling on primarily two interrelated rationales. First, the Court stated a preference for treating defenses identified in the same § 2254 Rule similarly. In this respect, it observed that although § 2254 Rule 5(b) requires the state in its answer to a habeas petition to “state whether any claim in the petition is barred by a failure to exhaust state remedies, a procedural bar, nonre-troactivity, or a statute of limitations,” § 2254 R. 5(b), the Supreme Court has held that federal courts may consider the defenses of exhaustion and nonretroactivity, even if the state has failed to raise those defenses. Day, 547 U.S. at 206, 126 S.Ct. 1675. And it continued, noting that the United States Circuit Courts “have unanimously held that, in appropriate circumstances, courts, on their own initiative, may raise a petitioner’s procedural default .... ” Id. Since courts may on their own raise all other defenses set forth in Rule 5(b), § 2254 Rules, the Court reasoned, it makes sense to treat the only remaining defense in that rule—timeliness—the same way.
Second, and . more significantly, the Court opined that like the doctrines of exhaustion, procedural bar, and nonre-troactivity, AEDPA’s statute of limitations is predicated on “values beyond the concerns of the parties.” Day, 547 U.S. at 205, 126 S.Ct. 1675 (citation and quotation marks omitted). Specifically, the Court explained, “The AEDPA statute of limitation promotes judicial efficiency and conservation of judicial resources, safeguards the accuracy of state court judgments by requiring resolution of constitutional questions while the record is fresh, and lends finality to state court judgments within a reasonable time.” Id.
Because-waiver is a threshold defense like timeliness, exhaustion, procedural bar, and nonretroactivity, the Day line of cases may apply to the affirmative defense of a collateral-action waiver. If so, the district court had the authority to raise the waiver itself once the government failed to do so in its response to Burgess’s § 2255 motion.
Nevertheless, in Day, the Supreme Court concluded that a court’s ability to revive a forfeited defense identified -in § .2254 Rule 5(b) is not without limits. Id. at 202, 210-11, 126 S.Ct. 1675. First, if a court -contemplates exercising its authority to invoke a forfeited § 2254 Rule 5(b) defense, that court must first give the parties “fair notice and an opportunity to present their positions” concerning whether the court should apply the defense. Day, 547 U.S. at 210, 126 S.Ct. 1675.
Second, a court may not “override a State’s deliberate waiver” of § 2254 Rule 5(b) defenses. Wood v. Milyard, 566 U.S. 463, 466-73, 132 S.Ct. 1826, 1833-34, 182 L.Ed.2d 733 (2012) (quoting Day, 547 U.S. at 202, 126 S.Ct. 1675); see also id. at 1833 n.5 (clarifying that Day “made clear .,. that a federal court has the authority to resurrect only forfeited defenses,” not waived ones). Otherwise, the court would violate “the principle of party presentation basic to opr adversary system.” Id. at 1833 (citation omitted).
Third, a court may not rely on a forfeited § 2254 Rule '5(b) defense where the state has “strategically withheld the defense,” as opposed to having inadvertently overlooked it. Day, 547 U.S. at 211, 126 S.Ct. 1675 (quotation marks omitted). And finally, in deciding whether to exercise its authority to apply a forfeited § 2254 Rule 5(b) defense, the court must ensure that “the petitioner is not significantly prejudiced by the delayed focus on the [forfeited defense], and determine whether the interests of justice would be better served by addressing the merits or by dismissing the petition [on the forfeited defense].” Id. at 210, 126 S.Ct. 1675 (citation and quotation marks omitted).
So even if the Day line of cases applies and the district court had the authority to raise the collateral-action waiver on its own initiative, the district court still had to comply with the constraints on its authority before it could dismiss the motion on that basis. In particular, the court first had to give the parties fair notice and a chance to present their positions on the collateral-action-waiver defense, and it had to consider the parties’ respective positions. It also had to determine whether any delay, in the application of the collaterahaction waiver significantly prejudiced Burgess and “whether the interests of justice would be better served by addressing the merits.” Id. at 210, 126 S.Ct. 1675 (citation and quotation marks omitted).
C. Which line of reasoning applies to the ' appeal-waiver defense?
We conclude that the rules pertaining to civil cases, not the Day line of reasoning, governs whether a district court has the authority to sita sponte invoke a collateral-action waiver to dismiss a § 2255 motion. We reach this conclusion for three reasons.
First, the reasoning underlying the Day line of cases does not translate neatly to the context of the appeal-waiver defense. Beginning with the second and significantly more important basis for Day’s conclusion—that AEDPA’s statute of limitations accounts for “values beyond the concern of the parties”—we cannot .say that a collateral-action waiver implicates such values in the same way or to the same extent that the defenses of timeliness, exhaustion, procedural bar, and nonretroactivity do.
Unlike a collateral-action waiver, which only certain criminal defendants opt to enter into, all prisoners are bound by the statute of limitations and the doctrines of exhaustion, procedural bar, and nonre-troactivity. And that is so because Congress and the Judiciary6 have determined that the universally applicable rules that the statute of limitations and these doctrines impose represent a proper balancing of society’s interests in finality, conservation of judicial resources, and comity (in the case of § 2254-petitions), on the one side, and the individual’s interest in having his habeas claim heard and society’s interest in ensuring that a prisoner has been convicted and sentenced within the bounds of the law, on the other.
- But Congress could not enact legislation, and the Judiciary could not create a judicial-rule, requiring all criminal defendants to waive all collateral actions, because that would likely violate the Constitution’s restrictions on suspending the right to petition for habeas corpus. U.S. Const, art. I, § 9, cl. 2. Indeed, our Constitution’s-Suspension Clause reflects the determination that the proper balancing of society’s interests in finality, conservation of judicial resources, and comity, against the individual and society’s interest in ensuring that a prisoner has been convicted and sentenced within the bounds of the law, see, e.g., Welch v. United States, - U.S. -, 136 S.Ct. 1257, 1266, 194 L.Ed.2d 387 (2016) (discussing in the context of retroactivity doctrine societal interests in convictions and sentences that are “authorized by substantive law”), requires the availability of collateral review in at least some-instances. So unlike with the four defenses enumerated in § 2254, a district court’s invocation of a collateral-action waiver from a privately negotiated plea agreement does not reflect an institutionally determined judgment that concerns of finality and judicial economy generally outweigh the interests of ensuring that a defendant has been convicted and sentenced within the bounds of the law.
As for the Day Court’s other basis for its conclusion—that defenses listed in the same habeas rule should be treated in the same way—the application in that case was clear: the statute-of-limitations defense expressly appears in § 2254 Rule 5(b) alongside the defenses of non-exhaustion, procedural bar, and nonretroactivity. Here, however, the appeal-waiver defense is mentioned neither expressly nor implicitly in § 2255 Rule 5(b). That rule does require the government to provide information about a movant’s use of any other federal - remedies and evidentiary hearings—information that could allow a district court to discern the existence of a threshold defense such as a procedural or statutory bar. But § 2256 Rule 5(b) does not purport to put a collateral-appeal-waiver defense on the same footing as, for example, the defenses of statutory and procedural bars. That fact takes us outside the territory of Day and likewise removes a reason to treat a collateral-action-waiver defense the same way as a statutory or procedural bar.
Second, the usual rule in our party-presentation system requires the parties to invoke their own claims and defenses. As the Supreme Court has explained, “[W]e rely on the parties to frame the issues for decision and assign to courts the role of neutral arbiter of matters the parties present.” Greenlaw v. United States, 554 U.S. 237, 243, 128 S.Ct. 2559, 171 L.Ed.2d 399 (2008). If a court engages in what may be perceived as the bidding of one party by raising claims or defenses on its behalf, the court may cease to appear as a neutral arbiter, and that could be damaging to our system of justice. Abiding by the Federal Rules of Civil Procedure’s rules for raising affirmative defenses avoids that problem.
Third, the neutral-arbiter concern is particularly apt when the court invokes an affirmative defense on behalf of the government, where the only source of the defense stems from the plea agreement. Federal Rule of Criminal Procedure 11(c)(1) prohibits courts from participating in plea-negotiation discussions. Among other reasons for this rule, courts have explained that it “protects the integrity of the judicial process.” United States v. Casallas, 59 F.3d 1173, 1178 (11th Cir. 1995), abrogated on other grounds by United States v. Davila, 569 U.S. 597, 133 S.Ct. 2139, 186 L.Ed.2d 139 (2013) (quoting United States v. Bruce, 976 F.2d 552, 557-58 (9th Cir. 1992), abrogated on other grounds by Davila, 133 S. Ct. 2139) (quotation marks omitted). Insulating judges from plea-negotiations would hardly protect the judicial process’s integrity if courts could later, of their own volition, invoke the government’s benefits conferred by the agreement arising from those very negotiations.7
For these reasons, we conclude that the rules applying to civil cases govern here.8
IY.
Nevertheless, under the Federal Rules of Civil Procedure, a district court may entertain a motion to amend the pleadings if the government’s initial response to a movant’s § 2255 motion failed to invoke an available affirmative defense. See Day, 547 U.S. at 216-17 & 217 n.2, 126 S.Ct. 1675 (Scalia, J., dissenting); see also Fed. R. Civ. P. 15(a). As Justice Scalia observed, “Requiring the [government] to take the affirmative step of amending its own pleading at least observes the formalities of our adversary system, which is a nontrivial value i[n] itself.” Day, 547 U.S. at 217 n.2, 126 S.Ct. 1675 (Scalia, J., dissenting) (citation omitted). And once a party seeks to amend its pleadings, the Federal Rules of Civil Procedure instruct district courts to “freely give leave [to amend] when justice so requires.” Fed. R. Civ. P. 15(a)(2).
Amendment of pleadings, of course, can slow the judicial process and moot proceedings that have preceded the amendments. In an effort to streamline the proceedings and manage their dockets, district courts may make limited inquiry into litigants’ possible claims and defenses, without violating the party-presentation principle that animates our judicial system. Indeed, the Supreme Court has “long recognized that a district court possesses inherent powers that are governed not by rule or statute but by the control necessarily vested in courts to manage their own affairs so as to achieve the orderly and expeditious disposition of cases.” Dietz v. Bouldin, - U.S. -, 136 S.Ct. 1885, 1891, 195 L.Ed.2d 161 (2016) (citation and internal quotation marks omitted). So while a district court may not invoke a collateral-action waiver in a plea agreement, in a case where such a waiver exists, the court may ask the government to state whether it intends to rely on the waiver. Of course, if the government decides to do so, the district court must provide the movant with an opportunity to respond and be heard on the issue.
Y.
For the reasons discussed above, we vacate the district court’s order denying Burgess’s § 2255 motion to the extent that it dismissed Claim 5. We remand for further proceedings consistent with this opinion.
VACATED AND REMANDED.
