OPINION OF THE COURT
Frederick Ray, a former inmate in the Pennsylvania state prison system, appeals from the order of the District Court dismissing sua sponte Ray’s complaint against prison officials filed pursuant to 42 U.S.C. § 1988 (2001). 1 The District Court dismissed Ray’s complaint based on its determination that Ray had not “demonstrated” that he had exhausted his administrative remedies. Section 1997e(a) of the Prison Litigation Reform Act of 1996 (“PLRA”) provides that “[n]o action shall be brought with respect to prison conditions under section 1983 of this title, or any Federal law, by a prisoner confined in any jail, prison or other correctional facility until such administrative remedies as are available are exhausted.” 42 U.S.C. § 1997e(a) (2001).
Ray argues that the District Court erred in dismissing his complaint for two reasons. His principal argument is that the PLRA’s exhaustion requirement is an affirmative defense, to be alleged and proved by the defendants. This is a question of first impression for this court. Other courts of appeals have divided on this issue. Ray’s alternate argument is that even if we were to decide that the PLRA exhaustion requirement is not an affirmative defense, the District Court erred by imposing an improperly heightened pleading standard that required Ray not only to plead but also to prove his exhaustion in the complaint.
I.
FACTS AND PROCEDURAL HISTORY
In his complaint, Ray alleges that while he was a prisoner at the Pennsylvania State Correctional Institution at Hunting-don, he was twice assaulted by officers, who retaliated by filing groundless misconduct charges against him when he -told them he would sue. Ray, while still a *290 prisoner and using a printed form complaint provided to prisoners, filed a § 1983 complaint pro se in the District Court for the Middle District of Pennsylvania against the officers who allegedly assaulted him and other prison officials. In his complaint, Ray alleged that various officers and certain prison procedures violated his First, Fifth, Eighth and Fourteenth Amendment rights.
On the first page of the form complaint, under a caption entitled “Exhaustion of Administrative Remedies,” the form asked “Is there a grievance procedure available at your institution?”; “Have you filed a grievance concerning the facts relating to the complaint?”; and “Is the grievance process completed?” Ray checked “Yes” in response to all three questions. App. at 4.
Shortly after Ray filed his complaint, the District Court referred it to a Magistrate Judge. The Magistrate Judge filed a report and recommendation, recommending dismissal for failure to exhaust administrative remedies. According to the Magistrate Judge, “[W]hile the plaintiff alleges that he filed various grievances with respect to the claims which he now raises in his complaint, there is no indication from the plaintiffs complaint that he took any further action to properly exhaust his administrative remedies.” Supp. at 7.
Ray filed objections to the Magistrate Judge’s report, alleging that he had asserted the claims of assaults by prison guards as defenses to the misconduct charges made against him which charged him with a number of violations of prison rules. Those misconduct charges stemmed from the same altercations that are the subject of his § 1983 claims.
The misconduct charges brought against Ray were brought under Pennsylvania Department of Corrections’ Inmate Disciplinary and Restricted Housing Procedures, DC-ADM 801 (effective Sept. 20, 1994) (“Inmate Disciplinary Procedures”), Supp. App. at 1-11, which govern inmate violations of prison rules. The Inmate Disciplinary Procedures are distinct from the Consolidated Inmate Grievance Review System, DC-ADM 804 (effective Oct. 20, 1994) (“Inmate Grievance System”), Supp. at 45, which is designed to address inmate-initiated grievances. 2 In his objections to the Magistrate Judge’s Report, Ray asserted that grievances may not be filed for claims related to disciplinary proceedings. App. at 16-17.
In the disciplinary proceeding against Ray, a hearing examiner had dismissed all of the charges save one. The Inmate Disciplinary Procedures provide that “[n]o appeals from a finding of not guilty are permitted.” DC-ADM 801 VI(I)(l)(b), Supp. App. at 8. It is unclear whether prison officials interpret this clause to permit appeals from dismissals where no culpability determination is made, such as the dismissed misconduct charges against Ray.
Ray attached to his objections to the Magistrate Judge’s Report handwritten copies of a number of the misconduct charges, along with the letter from the Chief Hearing Examiner denying Ray’s appeal, which constituted the final administrative disposition of Ray’s appeal of the one guilty charge. That letter notes, “I [, the Chief Hearing Examiner,] have reviewed the entire record of these misconducts; including the misconduct report, the hearing report and relevant documents, your appeal to the Program Review Committee and their response, your appeal *291 to the Superintendent and his response.” App. at 23. This litany of appeals precisely tracks the full panoply of available administrative appeals provided for by the Inmate Disciplinary Procedures. The Commonwealth does not argue otherwise.
On May 3, 1999, before the defendants were served, the District Court dismissed Ray’s complaint based on its assessment that Ray had not demonstrated exhaustion of administrative remedies. 3 The District Court stated that Ray had “not attached copies of [his various] grievances to his objections [to the Magistrate Judge’s report].” Supp. at 3. The District Court also observed that Ray had not set forth the specific steps that he had taken to exhaust administrative remedies and concluded by noting, “[A]ny appeal from this order will be deemed frivolous, without probable cause and not taken in good faith.” Supp. at 4.
II.
JURISDICTION AND STANDARD OF REVIEW
The District Court dismissed Ray’s complaint without prejudice. Appeal from a dismissal without prejudice is permitted under 28 U.S.C. § 1291 when a plaintiff “declares his intention to stand on his complaint or when he cannot cure the defect in his complaint.”
Booth v. Churner,
Ray states that he “intends to stand on his Complaint.” Br. of Appellant at 1. He also contends that he can no longer pursue administrative remedies due to the passage of time and his release from prison. We have previously exercised jurisdiction when “both parties agree that the time is long past for [the inmate-appellant] to pursue his normal administrative remedies [preventing him from] curfing] the defect in his complaint on which the District Court based its dismissal.”
Booth,
This court subjects district court decisions interpreting statutes to plenary review.

DISCUSSION
A. Exhaustion As An Affirmative Defense
Ray argues the District Court erred in dismissing his complaint for failure to exhaust administrative remedies and in failing to recognize that the PLRA exhaustion requirement in 42 U.S.C. § 1997e(a) is an affirmative defense. Ray does not dispute that the language of § 1997e(a) requiring administrative exhaustion of claims with respect to prison conditions applies to claims of excessive force by prison guards. If there had been any question about that, it was settled by the Supreme Court’s recent decision in
Porter v. Nussle,
534
*292
U.S. 516,
In support of his argument that failure to exhaust the prison’s administrative remedies is an affirmative defense that must be pleaded and proven by the defendants in a PLRA suit, Ray relies on this court’s decision in
Williams v. Runyon,
Courts in addition to this one have treated the exhaustion requirements of Title VII and the Age Discrimination in Employment Act (ADEA) as affirmative defenses.
See, e.g., Wyatt v. Terhune,
Ray argues that the purposes for the exhaustion requirement in Title VII suits are similar to those for the exhaustion requirement in PLRA suits and therefore the same pleading requirement should follow. We have, in another context, described the purposes that underlie a statutory requirement of exhaustion of administrative remedies. In
Heywood v. Cruzan Motors, Inc.,
1) promotes administrative efficiency by “preventing premature interference with the agency processes,”
2) respects executive autonomy by allowing an agency the “opportunity to correct its own errors,”
3) facilitates judicial review by affording courts the benefit of the agency’s experience and expertise, and
4) serves judicial economy by having the agency or other tribunal rather than the district court, compile the factual record.
Id.
at 370 (quoting
Cerro Metal Prods. v. Marshall,
Ray notes that in
Nyhuis v. Reno,
Although this is the first time we have faced how the PLRA’s exhaustion requirement should be pled,
5
six other circuits have considered the issue.
6
The Second, Seventh, Ninth and D.C. Circuits have held that the exhaustion requirement is an affirmative defense, akin to a statute of limitations.
See, e.g., Wyatt,
The Commonwealth relies on the contrary position held by the Sixth Circuit. In
Brown v. Toombs,
Although we agree with the
Brown
court that the plain language of the PLRA requiring that prisoners exhaust their administrative remedies before filing suit reflects the Congressional policy underlying the PLRA, the pleading rule
Brown
adopted does not necessarily follow. Congress appears to have had two primary concerns in enacting § 1997e(a). First, Congress expressed a desire to lessen the burden frivolous prison claims placed on federal courts.
See, e.g.,
141 Cong. Rec. 26,548 (1995) (“Frivolous lawsuits filed by prisoners tie up the courts, waste valuable legal resources, and affect the quality of justice enjoyed by law-abiding citizens.”) (statement of Sen. Dole);
see also Nyhuis,
These policies are not inconsistent with construing the exhaustion requirement of § 1997e(a) as an affirmative defense. Under § 1997e(c)(l) and (2), courts have the power to dismiss frivolous lawsuits sua sponte, handily fulfilling the first congressional policy and making it unnecessary to view § 1997e(a) as authorizing the same
*295
action. The second policy, that of giving prison administrators the opportunity to control the situation within the prison, is addressed by the exhaustion requirement itself. The rules of pleading and proof do not bear on that issue. In fact, an opinion by Judge Easterbrook of the Seventh Circuit suggests that prison officials may choose to waive exhaustion, presumably so that they can secure judicial imprimatur for some intractable disputes.
See, e.g., Perez,
We return therefore to our decision in
Williams
holding that defendants must plead and prove failure to exhaust as an affirmative defense.
See Williams,
In their discussion of categorizing affirmative defense, Wright and Miller recommend resort to “considerations of policy [and] fairness.” Wright & Miller, supra, § 1271, at 444. According to those authors,
“[fjairness” probably should be viewed as a shorthand expression reflecting the judgment that all or most of the relevant information on a particular element of a claim is within the control of one party or that one party has a unique nexus with the issue in question and therefore that party should bear the burden of affirmatively raising the matter.
Id.
at 445. Applying this consideration to the exhaustion requirement, it appears that it is considerably easier for a prison administrator to show a failure to exhaust than it is for a prisoner to demonstrate exhaustion. “[PJrison officials are likely to have greater legal expertise and, as important, superior access to prison administrative records in comparison to prisoners.”
Wyatt,
We thus join the many other circuits that have held that failure to exhaust is an affirmative defense to be pleaded by the defendant. 8
B. The District Court’s Pleading Requirements
In addition to holding that failure to exhaust is an affirmative defense, we find that the District Court erred in dismissing the complaint for failure to meet the heightened pleading requirement it imposed and in doing so sua sponte. The District Court’s sua sponte dismissal is inconsistent with the statutory structure of the PLRA. Subsection (c) of § 1997e, entitled “Dismissal,” provides for sua sponte dismissal by a district court for certain *296 enumerated reasons. The section provides:
(c) Dismissal
(1) The court shall on its own motion or on the motion of a party dismiss any action brought with respect to prison conditions under section 1983 of this title, or any other Federal law, by a prisoner confined in any jail, prison, or other correctional facility if the court is satisfied that the action is frivolous, malicious, fails to state a claim upon which relief can be granted, or seeks monetary relief from a defendant who is immune from such relief.
(2) In the event that a claim is, on its face, frivolous, malicious, fails to state a claim upon which relief can be granted, or seeks monetary relief from a defendant who is immune from such relief, the court may dismiss the underlying claim without first requiring the exhaustion of administrative remedies.
42 U.S.C. § 1997e(e).
Availing here is an application of the principle of
expressio unius est exclusio alterius
— when a statute specifically enumerates some categories, it impliedly excludes others.
See, e.g., Leatherman v. Tarrant County Narcotics Intelligence & Coordination Unit,
*297
As a general proposition, sua sponte dismissal is inappropriate unless the basis is apparent from the face of the complaint.
See, e.g., Rycoline Prods., Inc. v. C & W Unlimited,
The District Court also stated that Ray’s complaint was deficient because “Ray has not
demonstrated
that he has exhausted administrative remedies,” Supp. at 2 (emphasis added). In so stating, the court imposed the additional requirement that a prisoner must demonstrate compliance with the exhaustion requirement. We view that holding as inconsistent with the Supreme Court’s teachings in
Leatherman,
where the Court explained that courts should narrowly interpret statutory language to avoid heightened pleadings standards.
Most recently, in
Swierkiewicz v. Sorema,
Rule 8(a)’s simplified pleading standard applies to all civil actions, with limited exceptions. Rule 9(b), for example, provides for greater particularity in all averments of fraud or mistake. This Court, however, has declined to extend such exceptions to other contexts.
Id. at 4154 (footnote omitted). As we previously noted, no provision of the PLRA requires pleading exhaustion with particularity.
Ray asks us to use this occasion to clarify that a Pennsylvania inmate may satisfy his or her exhaustion obligation in the course of the proceedings charging the inmate with misconduct under the Inmate Disciplinary Procedures. We decline to so *298 hold. That issue should be considered in the first instance by the District Court because it may require information regarding how prison administrators interpret the scope of the Inmate Disciplinary Procedures, the Inmate Grievance System, and the interaction between them.
IV.
CONCLUSION
For the reasons set forth, we will reverse the decision of the District Court dismissing Ray’s complaint.
Notes
. Ray’s notice of appeal was filed pro se. This court sought representation for Ray from Professor Jon Romberg, Associate Director of the Center for Social Justice at Seton Hall University School of Law. Ray's appeal was handled by John P. Campbell and Craig T. Moran, who were at the time of briefing students at Seton Hall Law School under the supervision of Professor Romberg. Mr. Campbell and Mr. Moran had graduated by the time they argued before us, both capably, and we extend our appreciation to them and to Professor Romberg.
. Both the Inmate Disciplinary Procedures and the Inmate Grievance System have since been modified.
. Although the defendants in the action below made no appearance before this court, the Commonwealth of Pennsylvania appeared as an amicus curiae, filing a brief in support of the District Court's decision. A deputy attorney general ably argued the case.
. Neither the District Court nor the Commonwealth has suggested that the mandatory language of § 1997e(a) — "no action
shall
be brought” (emphasis added) — makes the exhaustion requirement a jurisdictional one. As this court held in
Nyhuis v. Reno,
. In its brief, Pennsylvania suggests this circuit confronted the procedural characterization of the PLRA’s exhaustion requirement in
Booth v. Churner,
. The district courts in this circuit are divided on whether the PLRA exhaustion requirement is an affirmative defense or some form of heightened pleading. Compare cases putting pleading burden on defendant,
see, e.g., Santiago v. Fields,
. The position of the Eighth Circuit is not clearly defined. In
McAlphin v. Morgan,
. We do not suggest that defendants may not raise failure to exhaust as the basis for a motion to dismiss in appropriate cases. The issue is not raised by this case, and neither party has stated its position.
See, e.g., Flight Sys., Inc. v. Elec. Data Sys. Corp.,
. The statutory structure also belies any possibility that a failure to exhaust is included in (c)(l)'s broad rubric of “failure to state a claim upon which relief can be granted.” As one court observed:
Any argument that Congress intended the broad categories in Section 1997e(c)(l) to include dismissal for failure to exhaust is demolished by Section 1997e(c)(2), which grants the court power to dismiss sua sponte without requiring exhaustion of administrative remedies. It makes little sense to permit dismissal for failure to exhaust and then state the court may dismiss without "first requiring the exhaustion of administrative remedies.”
Jackson,
. Moreover, failure to exhaust was not included when the PLRA amended the provision authorizing prisoner in forma pauperis suits to provide explicitly for sua sponte dismissal for certain specified reasons, see 28 U.S.C. § 1915(e)(2) (2001) (amended by Pub.L. 104-134, 110 Stat. 1321-74 (1996)) (permitting dismissals "at any time” for falsely alleging poverty, or because, inter alia, the action is frivolous or malicious), and also instituted a screening process for prisoner suits against governmental entities and their employees, see 28 U.S.C. § 1915A(a)-(b) (directing dismissal “before docketing, if feasible” for, among other grounds, claims which *297 seek monetary relief from defendants immune from such redress).
