In a prior retaliation action, Napoleon Hartsfield (Hartsfield), a prisoner in the Iowa State Penitentiary, successfully obtained a court order compelling the Iowa Department of Correction (IDC) not to destroy some of his legal papers, and to provide him access to the materials. Immediately after Hartsfield obtained this order, IDC correctional officers Deborah Nichols (Officer Nichols) and Travis Loza-no (Officer Lozano) submitted separate disciplinary reports against Hartsfield. Hartsfield was found guilty of the violations in prison disciplinary hearings, which resulted in detention and loss of earned time. Hartsfield filed this suit, claiming these disciplinary actions constituted retaliation for having successfully obtained the prior court order. Hartsfield also claimed violations of his right to access the courts. Upon initial review under 28 U.S.C. *828 § 1915A, the district court 1 determined Hartsfield alleged no injuries sufficient to maintain the access to the courts claim. The district court also granted summary judgment in favor of the defendants on the retaliation claim, finding the disciplinary actions were supported by “some evidence” and the claim was, therefore, barred. Both claims were dismissed, and Hartsfield challenges both dismissals on appeal. We affirm.
I. BACKGROUND
After Hartsfield filed a retaliation claim against the IDC warden, the district court 2 considered Hartsfield’s motion for an emergency temporary restraining order preventing IDC officials from destroying some of his legal documents. The district court construed the motion as one for preliminary relief. On October 18, 2004, the court granted Hartsfield’s motion, and ordered the IDC to file a report with the court after allowing Hartsfield to sort through his papers. 3
The following day, Officer Nichols filed a disciplinary notice against Hartsfield, charging him with (1) disobeying a lawful order; (2) verbal abuse; and (3) disruptive conduct. The report alleged Hartsfield had used loud and inappropriate language, and “this behavior had been noted on numerous other days,” and Hartsfield, nineteen days before, was advised of a “final warning.” Hartsfield denied the allegations, and claimed this was a retaliatory action against him because he filed the request for relief in federal court. Harts-field claims on October 19, 2004, Officer Nichols told Hartsfield, “Hartsfield your lawsuit means nothing, nor do your injunction [sic ] you still won’t be receiving your legal property I’ll just write you a report.” Hartsfield further stated he could not call any witnesses, because the report against him was so vague he could not determine toward which inmates he was accused of directing profanities. Considering only the written report and Hartsfield’s written denial, an independent hearing officer found Hartsfield guilty of the violations, and assessed thirty days disciplinary detention, and sixteen days loss of earned time. Hartsfield appealed, and the ruling was affirmed.
In a separate incident, on November 17, 2004, Officer Lozano filed a disciplinary report against Hartsfield, charging him with assault, threats/intimidation, verbal abuse and disruptive conduct. Officer Lozano, who was passing out books, alleged Hartsfield said to him, “you won’t be walking by my cell playing games much longer.” Officer Lozano further stated he asked Hartsfield if that should be taken as a threat, and Hartsfield replied, “write it up however you want.” Hartsfield filed a written statement denying the charge. Hartsfield contended the statement was taken out of context and he actually said, “you won’t be walking by my cell playing games much longer cause I’m going to file a grievance against you and file suit for discrimination.” Hartsfield admitted, when asked if this was a threat, he stated, “write it up however you want.” An independent hearing officer reviewed the written report and response and heard testimony from Hartsfield. The hearing officer *829 found Hartsfield guilty of the rules violations, and sanctioned him to thirty days disciplinary detention and a loss of sixteen days earned time. Hartsfield appealed this ruling, and the ruling was affirmed.
Hartsfield filed a lawsuit against Officer Nichols and Officer Lozano, accusing them of retaliatory conduct. Hartsfield also alleged the IDC officials intentionally denied him access to the courts by denying him access to law books within the law library, and adequate legal assistance from a prison attorney.
On January 18, 2005, the district court handed down an initial review order, finding Hartsfield’s retaliation claim was not frivolous, and allowing the claim to proceed. The court concluded Hartsfield alleged no injury sufficient to maintain the access to the courts claim. The court later granted the defendants’ motion for summary judgment on the retaliation claim. Hartsfield appeals both determinations.
II. DISCUSSION
We review the grant of summary judgment de novo, viewing the record most favorably to the non-moving party.
See Tipler v. Douglas County,
A. Retaliation
An inmate may maintain a cause of action for retaliatory discipline under 42 U.S.C. § 1983 where a prison official files disciplinary charges in retaliation for an inmate’s exercise of constitutional rights.
See Sprouse v. Babcock,
Based on these principles, the district court set forth to determine whether the sanctions Hartsfield received were valid. The district court explained, according to established law, prison disciplinary violations are valid when they are supported by “some evidence.” Viewing the evidence in the light most favorable to Hartsfield, the court determined Officer Nichols said “Hartsfield, your lawsuits mean nothing.” Nevertheless, the district court found, because there was “some evidence” supporting the validity of the disciplinary action, no retaliation claim could be maintained.
On appeal, Hartsfield does not dispute his claim would be foreclosed if the disciplinary action was supported by “some evidence.” Indeed, this standard seems well settled,
Goff,
Hartsfield argues legally sufficient evidence was not present to constitute “some evidence” he committed the charged violations. Hartsfield claims the only evidence available was the defendants’ uncorroborated allegations as set forth in their disciplinary reports. Hartsfield contends uncorroborated allegations of a correctional officer are insufficient to satisfy the “some evidence” standard because “[a] contrary holding would essentially preclude any inmate from ever bringing a retaliation claim.” This argument first ap *830 pears well taken. After all, if Hartsfield is precluded from maintaining suit, correctional officers would be nearly free to retaliate against prisoners for exercising constitutional rights, so long as the officers write up a report directly maintaining the prisoner violated a valid prison rule, and a hearing officer accepts the officer’s view of the matter over that of the prisoner.
However, Hartsfield is incorrect such a holding would automatically “preclude any inmate from
ever
bringing a retaliation claim.” The Supreme Court has outlined procedures correctional facilities must follow to conduct an impartial due process hearing on a disciplinary matter.
See Wolff v. McDonnell,
Hartsfield relies on
Moore v. Plaster,
First, Hartsfield’s assertion stretches Moore in some ways. In Moore, three prison disciplinary actions were at issue. Id. at 931. The evidence available to support the first and third disciplinary actions against the inmate consisted only of the investigator’s report, which included a bare accusation that the inmate “conspired to have narcotics brought into [the facility].” Id. at 931-32. The investigator’s report was not based upon the investigator’s personal knowledge. Id. Thus, this court found the report was insufficient to qualify as “some evidence” of a rules violation. Id. at 932. Hartsfield’s case is distinguishable, because the two reports relied upon were based upon the investigators’ personal knowledge and did not simply contain bare accusations that a rule was violated. Rather, the reports detailed the conduct underlying the charges, with one report identifying other earlier dates of similar conduct, including the earlier date and time when Hartsfield was advised of a “final warning.”
The second disciplinary action in
Moore
was supported by the observations of the reporting officer.
Id.
However, the reporting officer’s observation was again only eonclusory in nature, and was also supported by a notation in the report that “Investigator Plaster stated that inmate Moore failed the [lie detector] exam.”
Id.
Our court noted, “[o]rdinarily, the Investigator’s statement of the test results would be ‘some evidence,’ but here that very statement is itself alleged to be retaliatory.”
Id.
The court found this statement could not constitute “some evidence” sufficient enough to support a rule violation.
Id.
This portion of
Moore
potentially helps Hartsfield. Again, Hartsfield’s situation is distinguishable from the problem of Moore’s report being only eonclusory in nature, given the reports against Harts-field were specific. Nonetheless, like the situation in
Moore,
“here, [the] very [reported accusations themselves are] alleged to be retaliatory.”
Moore,
*831
The
Moore
court reasoned this disputed evidence situation was distinguishable from that in
Henderson v. Baird,
Thus, in the one manner in which the
Moore
holding helps Hartsfield’s case,
Moore
was otherwise bound by this court’s prior precedent.
See Goff,
Hrbek complains that if disciplinary committees are held only to a “some evidence” standard by the Constitution, the Wolff hearing requirement becomes meaningless because a guard’s written report alone constitutes “some evidence.” We agree that disciplinary actions may be taken&emdash;and often they are&emdash;based only on a guard’s report. Even when there is substantial evidence to the contrary, the committee may find a guard’s report to be credible and therefore take disciplinary action. However, the Wolff hearing ensures that the inmate has an opportunity to persuade an impartial decisionmaker, who must give written justification for his decision, that discipline is not warranted. This is the interest protected by the Constitution.
Id. (citations and footnote reference omitted) (emphasis added). Thus, taking Hrbek and Henderson together, a report from a correctional officer, even if disputed by the inmate and supported by no other evidence, legally suffices as “some evidence” upon which to base a prison disciplinary violation, if the violation is found by an impartial decisionmaker. We therefore apply Hrbek and Henderson, 4 Under this precedent, Hartsfield’s disciplinary violations are sufficiently supported by some evidence, and the district court properly granted summary judgment on the retaliation claim.
B. Access to the Courts
“To prove a violation of the right of meaningful access to the courts, a prisoner must establish the state has not provided an opportunity to litigate a claim challenging the prisoner’s sentence or conditions of confinement in a court of law, which resulted in actual injury, that is, the hindrance of a nonfrivolous and arguably meritorious underlying legal claim.”
White v. Kautzky,
Hartsfield first claims the district court erred in dismissing this claim because the court did “not explicitly state whether the dismissal [was] for failure to state a claim or because it was frivolous.” This contention lacks merit. The district court quite clearly articulated that Hartsfield cannot maintain a claim because he cannot demonstrate actual injury. Because actual injury is required, the district court implicitly, if not expressly, found Hartsfield’s claim was one upon which relief could not be granted.
Hartsfield also contends the district court erred in dismissing this claim because he argued the IDC’s “conduct precluded him from filing post-conviction relief,” which would suffice as actual injury. As the district court explained, Hartsfield did not actually contend the IDC’s actions blocked him from being able to file for relief. Rather, Hartsfield only assumed any filing would fail due to his lack of legal knowledge and information. Id. The record supports this finding. Hartsfield’s complaint concludes the IDC denied him access to the courts, and asserts this was due to his lack of access to law books and free legal assistance. As the United States Supreme Court has articulated:
Because [precedent] did not create an abstract, freestanding right to a law library or legal assistance, an inmate cannot establish relevant actual injury simply by establishing that his prison’s law library or legal assistance program is subpar in some theoretical sense. That would be the precise analog of the healthy inmate claiming constitutional violation because of the inadequacy of the prison infirmary ... [T]he inmate therefore must go one step further and demonstrate that the alleged shortcomings in the library or legal assistance program hindered his efforts to pursue a legal claim. He might show, for example, that a complaint he prepared was dismissed for failure to satisfy some technical requirement which, because of deficiencies in the prison’s legal assistance facilities, he could not have known. Or that he had suffered arguably actionable harm that he wished to bring before the courts, but was so stymied by inadequacies of the law library that he was unable even to file a complaint.
Casey,
Finally, Hartsfield argues the district court erred by sua sponte dismissing the claim without giving him leave to amend the complaint. Hartsfield contends that “[dismissal is warranted only if the face of the complaint shows an insuperable bar to relief.” Hartsfield asserts his complaint “alleges multiple acts of the Appellees which, if true, constitute a deprivation of his right to access the courts,” including the alleged statements from Officer Nichols that “You still won’t be receiving your legal property. I’ll just write you a report.” Hartsfield confuses the offense with the injury. Although he has alleged facts which, if true, could constitute a
*833
wrong,
he has not, for the reasons outlined above, articulated any manner in which he was
injured by
the offense. Absent an articulation of how the alleged wrongful conduct actually blocked Hartsfield’s access to filing a complaint, or caused a filed complaint to be deficient, Hartsfield’s alleged injuries are merely speculative. Because no further explanation of the facts alleged could change this speculation, the district court did not err in dismissing the complaint without leave to amend.
See Williams v. Dep’t of Corrs.,
III. CONCLUSION
Although there appears to be conflicting case law on one aspect of the retaliation issue, our prior controlling precedent establishes a correction officer’s report, even if standing alone and disputed, suffices as “some evidence” on a disputed fact when deemed credible in an impartial hearing. As to the access to the courts claim, Harts-field failed to articulate how he suffered an actual injury. The district court’s judgments are affirmed.
