FOR PUBLICATION UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT NEIL GRENNING, No. 23-3018 D.C. No. Plaintiff - Appellant, 2:22-cv-00136- MKD v. JAMES R KEY, sued in his official OPINION and individual capacities; ANN WISE, sued in her official and individual capacities, Defendants - Appellees. Appeal from the United States District Court for the Eastern District of Washington Mary K. Dimke, District Judge, Presiding Argued and Submitted February 11, 2026 Seattle, Washington Filed August 26, 2026 Before: M. Margaret McKeown, William A. Fletcher, and Patrick J. Bumatay, Circuit Judges. Opinion by Judge McKeown; Dissent by Judge Bumatay 2 GRENNING V. KEY SUMMARY * First Amendment The panel reversed the district court’s summary judgment for prison officials and remanded in Neil Grenning’s 42 U.S.C. § 1983 action alleging that his First Amendment rights were violated when prison officials refused to submit a story he wrote to a university literary journal. While incarcerated, Grenning participated in a prison writing program and wrote a short story that referred to a moment of sexual intimacy. When he submitted his story to a university journal affiliated with the writing program, defendant Ann Wise, the prison’s Community Partnership Program Coordinator, intercepted his outgoing story and returned it to him because she deemed it “inappropriate for publication” because of its “sexual content.” Grenning then mailed the story directly to the university and complained to defendant James Key, the prison superintendent. Key subsequently endorsed the decision to block Grenning’s submission and warned Grenning he would be removed from the writing program if he again sent correspondence directly to a journal volunteer without prior approval. Grenning filed suit, alleging that the prison violated his First Amendment rights by censoring his submission and retaliating against him for exercising those rights. The district court granted the prison’s summary judgment motion, deciding that Wise and Key had not violated * This summary constitutes no part of the opinion of the court. It has been prepared by court staff for the convenience of the reader. GRENNING V. KEY 3 Grenning’s First Amendment rights, and even if they had violated Grenning’s rights, their actions were protected by qualified immunity. The district court also found no retaliation. Reversing the district court’s summary judgment order, including its qualified immunity determination, the panel held that the district court erred by applying the standard in Turner v. Safley, 482 U.S. 78 (1987), which governs most regulations of prisoner conduct, instead of the standard from Procunier v. Martinez, 416 U.S. 396 (1974), which governs outgoing inmate correspondence. Because Grenning’s censorship claim turns on a prison official’s content-driven screening of outgoing inmate correspondence, Martinez applied. The panel held that viewed in the light most favorable to Grenning, the record demonstrates genuine disputes of fact, which, if proven at trial, would support the conclusion that Wise’s refusal to transmit Grenning’s story to the university journal constituted censorship prohibited by the First Amendment. Furthermore, Martinez clearly established Grenning’s right not to have prison officials refuse to transmit his nonthreatening outgoing correspondence to an outside recipient because they disapproved of its content or feared the public’s reaction to it. The panel noted that they would be compelled to reverse even if Turner applied because there was no valid, rational connection between the decision to bar Grenning’s story and the asserted penological interests. The panel further held that the district court erred in granting summary judgment on Grenning’s retaliation claim by relying on an Eighth Amendment retaliation case. On remand, the district court should address the claim under 4 GRENNING V. KEY Rhodes v. Robinson, 408 F.3d 559 (9th Cir. 2005), which sets forth the basic elements for a viable claim of First Amendment retaliation in the prison context. Dissenting, Jude Bumatay would apply Turner’s deferential standard and conclude that there was no First Amendment violation. Even if there were a First Amendment violation, he would hold that Wise and Key are entitled to qualified immunity because Grenning’s right to publish work—without approval—created while participating in a prison program was not clearly established at the time of Wise and Key’s conduct. Judge Bumatay would also affirm the district court’s summary judgment for Key on the retaliation claim, because Key’s threat was a result of Grenning violating the writing program’s policies, not “because of” Grenning’s protected conduct.

KEY 5 OPINION McKEOWN, Circuit Judge: Free speech does not vanish at the prison gate. In the course of his incarceration and as part of a prison writing program, Neil Grenning wrote a short story that referred to a moment of sexual intimacy. When he submitted his story to a university journal affiliated with the writing program, a prison employee barred the story as “inappropriate for publication” because of its “sexual content.” Grenning then mailed the story directly to the university and complained to the prison superintendent, who subsequently endorsed the decision to block his submission. The superintendent also warned Grenning that if he ever again sent correspondence directly to a journal volunteer without prior approval, he would be removed from the writing program. In rejecting Grenning’s First Amendment censorship claim, the district court sidestepped the standard that governs outgoing inmate correspondence as laid out in Procunier v. Martinez, 416 U.S. 396 (1974). The court also misconstrued the standard that applies to Grenning’s retaliation claim. We reverse and remand. Background Grenning is an inmate at Airway Heights Corrections Center (“the prison”) serving a sentence for multiple sex crime convictions. While incarcerated, Grenning enrolled in a writing program. The Writers in the Community course is sponsored by Eastern Washington University (“EWU” or “the university”) and encourages participants to develop their writing skills and submit their work for potential publication in InRoads, a literary journal. 6 GRENNING V. KEY Writers in the Community courses are held in various settings in and around Spokane, and InRoads publishes works by participants of all ages, including elementary school students. The writing program informed enrolled inmates that to be submitted to InRoads, their works needed to be “approved” by Ann Wise, the prison’s Community Partnership Program Coordinator. Everyone, prisoner or otherwise, who submitted their writing to InRoads had to acknowledge that “the audience of InRoads includes children and special populations, sensitive to any kind of explicit material.” The submission agreement cautioned that InRoads may feature “[m]ature themes and adult language,” with “inclusion in InRoads . . . left to the managing editor’s discretion.” Prior works published in InRoads had included references to rape, teen pregnancy, drug use, suicide, arson, and death. The Writers in the Community syllabus required students to read books that included depictions of a young woman’s sexual assault by a group of boys (Sandra Cisneros’s The House on Mango Street) and a character’s fantasy of forcefully carrying a woman upstairs and tying her to a bed (Tim O’Brien’s The Things They Carried). As part of the program, Grenning wrote “Dark Room,” a short story that explored the protagonist’s relationship with his daughter, Kayla, and his attempts to talk to Kayla about his wife, who had died by suicide. “Dark Room” described a moment of sexual intimacy with his late wife: Smell of her breath after jogging a mile to Einstein’s Bagels and back before dawn. Before she was pregnant. Before five hours of labor ended with you. That fiery sweat of exuberant energy when we screwed barefoot against the unfinish drywall of the washroom. GRENNING V. KEY 7 I smell fresh caulk and syrup sticky sex the same way. Time before Diagnosed Conditions ending in Ideation. None of which I can explain to Kayla. Grenning read this story to his class, and one of the instructors told him that it was “well-written” and “close to being finished.” The Washington Department of Corrections policy governing publications states that “[m]ail to or from offenders, including publications . . . may be rejected” if the “[p]ublications . . . contain significant or repeated instances of content defined per WAC 137-48-020(13)(a)-(b) . . . .” The Washington regulation cited in the policy defines “[s]exually explicit materials” to describe, among others, “a sex act which includes, but is not limited to, genital-genital, oral-genital, anal-genital, or oral-anal contact/penetration, genital or anal contact/penetration with an inanimate object, masturbation, and/or bodily excretory behavior.” WAC 137-48-020(13)(b). The policy also states that “[p]ublications with content that violates any Department policy or facility specific procedure will be referred to the Publication Review Committee for further review and a final decision” and that “[p]ublications initially rejected as sexually explicit material per WAC 137-48-020 may be approved by the committee for artistic, health/medical, and educational purposes.” The policy further prescribes general rules for outgoing mail, including that envelopes “be stamped with the following or similar message: ‘This was mailed by an offender confined at the Washington State Department of Corrections facility. Its contents are uncensored.’” In this appeal, the prison officials 8 GRENNING V. KEY acknowledge that Grenning’s story “was not graphic enough to violate the prison’s restrictions.” Wise had requested that the Writers in the Community staff route all submissions to InRoads through her. After Grenning submitted his story to program staff, Wise reviewed it and barred it from publication. In her note to Grenning after intercepting his story, Wise stated: “Due to sexual content this writing submission is inappropriate for publication in the InRoads Book that includes distribution to minors.” Wise did not cite any policy that the story allegedly violated. Nor is there indication that Grenning’s story was ever reviewed by the Publications Review Committee. Facing Wise’s interception, Grenning mailed his story directly to Eastern Washington University. He also wrote a letter to prison superintendent James Key, objecting to Wise’s interception and letting Key know that he had mailed the story to the university. Key responded: It is the responsibility of the [Community Partnership Program Coordinator] to ensure nothing leaves the institution through the volunteer program that could cause some negative publicity for the facility and department. I concur with her decision to not allow your story to be published by the volunteer group Writers in the Community. You stated in your letter that you had to send your story directly to EWU. This causes me concern, as you have bypassed our established processes. Policy does not allow for the volunteers to accept any correspondence without prior approval. If GRENNING V. KEY 9 you send any correspondence directly to a volunteer again without prior approval, you will not be allowed to participate in this volunteer program. After receiving the message from Key, Grenning filed a grievance with the prison. In notes taken after a meeting with the grievance coordinator, Grenning wrote that the coordinator “said he did not know any reason why [Grenning] would not be able to send material to a university through the mail.” Unbeknownst to Grenning, Wise also corresponded with the InRoads staff. A student director offered to edit “Dark Room” to address the concerns: “I have no objection to to [sic] attempting to edit the story in such a way that the problematic paragraph can be dropped entirely[.]” The student director also acknowledged that “even if Ann [Wise] had approved the piece in question,” InRoads editorial staff “would most likely not have approved it after that (or only with cuts).” Wise asked the student director to send the story back to Grenning and tell him, “Thank you for your submission but this needs to go through the proper channels at the prison.” After his internal efforts went nowhere, Grenning filed this lawsuit and alleged that Key, Wise, and the prison violated his First Amendment rights by censoring his submission and retaliating against him for exercising those rights. He immediately sought discovery and requested that the prison produce the policy that governs screening of inmate publications as well as Wise’s job description that authorized her to bar submissions to InRoads. It appears that the prison did not produce the requested documents by the required deadline. When Grenning served requests for 10 GRENNING V. KEY admission to Key and Wise after the discovery deadline, they replied that the requests were untimely. Stymied on discovery requests not fully answered, Grenning filed a motion to stay summary judgment until he had received the discovery. Later, when the prison moved for summary judgment and Grenning attempted to file an opposition through the prison counselor, the scanned document was apparently never forwarded to the legal librarian for electronic filing. The district court granted the prison’s summary judgment motion, deciding that Wise and Key had not violated Grenning’s First Amendment rights because the prison had “an important government interest in preventing inmates from using their educational programs to disseminate sexual material to children” and “an interest in ensuring nothing leaves the institution through the [Writers in the Community] that could cause negative publicity for the facility or department,” protected by Turner v. Safley, 482 U.S. 78 (1987). The court further decided that even if Key and Wise’s refusal to transmit “Dark Room” to InRoads had violated Grenning’s rights, their actions were protected by qualified immunity. The court also found no retaliation and denied Grenning’s motion to stay the summary judgment proceedings pending receipt of discovery. Grenning’s motion to vacate and set aside the judgment under Rule 59(e) was denied. With the benefit of pro bono counsel, Grenning timely appealed the denial of summary judgment and the motion to vacate and set aside the judgment. 1 1 Grenning’s pro bono counsel has capably discharged his responsibility, and we thank him for his substantial efforts. GRENNING V. KEY 11 Analysis Grenning’s appeal turns on two constitutional theories and two claims of procedural error. He argues that Wise’s refusal to forward his short story to InRoads constituted censorship that violated the First Amendment, and that those rights were clearly established at the time of the violation. He also contends that Key’s threat to expel him from the writing program was “textbook retaliation” in violation of the First Amendment. Separately, Grenning claims that the district court wrongly denied him additional discovery despite his diligence and the demonstrated effect of that discovery on the summary judgment decision. He finally argues that the district court’s refusal to consider his belated opposition brief violated Rule 56. The parties focused most of their time on the censorship claim, which is a logical starting point. I. Censorship The parties acknowledge the baseline principle that “[t]here is no iron curtain drawn between the Constitution and the prisons of this country.” Wolff v. McDonnell, 418 U.S. 539, 555–56 (1974). Grenning does not argue that he has a constitutionally protected right to publication in InRoads. See Pell v. Procunier, 417 U.S. 817, 821–22 (1974). We address instead whether Grenning had a right to have his story transmitted to the journal for consideration. Reviewing de novo the district court’s summary judgment order, including its qualified immunity determination, we reverse. See Dodge v. Evergreen Sch. Dist. #114, 56 F.4th 767, 776 (9th Cir. 2022). The district court applied the four-factor test from Turner, which governs most regulations of prisoner conduct, instead of the standard from Martinez, which continues to apply to 12 GRENNING V. KEY outgoing inmate correspondence. Viewed in the light most favorable to Grenning, id., the record demonstrates genuine disputes of fact, which, if proven at trial, would support the conclusion that Wise’s refusal to transmit “Dark Room” to InRoads constituted censorship prohibited by the First Amendment. See Martinez, 416 U.S. at 413–15. Martinez and its progeny clearly established Grenning’s right not to have prison officials refuse to transmit his nonthreatening outgoing correspondence to an outside recipient because they disapproved of its content or feared the public’s reaction to it, unless the officials could establish a sufficiently close fit between the restrictions and a concrete substantial or important interest in security, order, or rehabilitation. See id.; Barrett v. Belleque, 544 F.3d 1060, 1062 (9th Cir. 2008) (per curiam). We conclude that Martinez applies because this claim, like the ones asserted in Martinez, turns on a prison official’s content-driven screening of outgoing inmate correspondence. Martinez announced the following standard under which “censorship of prisoner mail is justified”: First, the regulation or practice in question must further an important or substantial governmental interest unrelated to the suppression of expression. Prison officials may not censor inmate correspondence simply to eliminate unflattering or unwelcome opinions or factually inaccurate statements. Rather, they must show that a regulation authorizing mail censorship furthers one or more of the substantial governmental interests of security, order, and GRENNING V. KEY 13 rehabilitation. Second, the limitation of First Amendment freedoms must be no greater than is necessary or essential to the protection of the particular governmental interest involved. Thus a restriction on inmate correspondence that furthers an important or substantial interest of penal administration will nevertheless be invalid if its sweep is unnecessarily broad. Id. at 413–14. As the Court explained, the “interest of prisoners and their correspondents in uncensored communication by letter, grounded as it is in the First Amendment, is plainly a ‘liberty’ interest within the meaning of the Fourteenth Amendment even though qualified of necessity by the circumstance of imprisonment.” Id. at 418. That liberty interest accordingly demands appropriate “minimum procedural safeguards.” Id. at 417. The standard announced in Martinez governs this case. 2 Indeed, both Grenning’s case and Martinez involve a strikingly similar sequence of constitutionally relevant facts. Wise’s actions echo those of the officials in Martinez, who screened “outgoing personal mail” and, when they disapproved of a prisoner’s writing, could “refuse to mail or deliver the letter and return it to the author.” Id. at 399–400. One of the rules that the Court held unconstitutional permitted prison officials to censor correspondences that they deemed “lewd” or “obscene.” Id. at 400. Wise, too, 2 We reject the argument that the First Amendment is not implicated because “Dark Room” eventually made it to InRoads. The very “refus[al] to mail or deliver” outgoing inmate correspondence may constitute censorship, even if that correspondence reaches its destination by other means. Martinez, 416 U.S. at 400, 417. 14 GRENNING V. KEY intercepted Grenning’s outgoing short story and returned it to him because she deemed the story “inappropriate for publication” because of its “sexual content.” The rejection came even though other issues of InRoads had allowed “[m]ature themes and adult language,” and the syllabus had assigned works containing substantially more explicit material and stated only that “[s]ubmissions with graphic content” would be returned. Wise’s rejection lacked any explanation based on “the substantial governmental interests of security, order, and rehabilitation” that the Court has recognized as constitutionally valid. Id. at 413. Rather, her decision turned on elastic, content-based “discretion[ary]” judgments—precisely what was deemed unconstitutional in Martinez. Id. at 415. The rationale that Key eventually provided in Grenning’s case—that Wise had “to ensure nothing leaves the institution” that might cause “negative publicity” to the prison—mirrors the logic of the rules invalidated in Martinez that worked “simply to eliminate unflattering or unwelcome” perspectives, and “invited prison officials . . . to apply their own personal prejudices and opinions.” Id. at 413, 415. The adequacy of the prison’s rationale goes to the legitimacy of the penological interests asserted, whether the restrictions imposed were generally necessary to give effect to those interests, and the procedural rights that Grenning was guaranteed. Indeed, Grenning was guaranteed “minimum procedural safeguards,” possibly including review from the Publications Review Committee. Id. at 417. There is no indication in the record that the prison made good on that guarantee. If proven at trial, that failure would show that Grenning was deprived of the opportunity to have “Dark Room” considered by InRoads without impediment by the prison. These similarities demonstrate that Grenning’s case clearly comes within Martinez’s ambit. GRENNING V. KEY 15 To be sure, rehabilitation is a “legitimate penological interest[],” see Turner, 482 U.S. at 89, and an “important or substantial” one, Martinez, 416 U.S. at 413. But the broad claim that censoring Grenning’s story satisfies the goal of rehabilitation as one of “enhancing community safety, reducing recidivism, and achieving accountability through effective correctional programs,” Brief for Appellees at 7, does not meet Martinez’s “less deferential” standard. Thornburgh v. Abbott, 490 U.S. 401, 409 (1989). If we accepted that level of generality, rehabilitation would stop being an important or substantial governmental interest and become the exception that swallows the rule. On this view, an official could suppress any content that she deems inconsistent with conclusory assertions of “accountability,” “appropriate communication standards,” or “appropriate boundaries” by claiming that doing so would be rehabilitative. Brief for Appellees at 37. The Martinez standard requires “a closer fit,” with regulations on outbound mail tailored to prevent “danger to the community inside the prison.” Thornburgh, 490 U.S. at 411–12. Nor can the specter of “negative publicity” to the prison justify the rejection. Brief for Appellees at 38. 3 Simply put, the record supports the view that Key and Wise refused to allow Grenning’s written expression to leave the prison based on its content. That the intended destination 3 The Court in Thornburgh clarified that Martinez did not impose a “least restrictive means requirement,” Thornburgh, 490 U.S. at 411, and we do not endorse one here. Contra Dissent at 38–40. But neither Turner, which the dissent favors, see Dissent at 34–38, nor Martinez, which the dissent would sub silentio overturn, id. at 38–39, blessed the use of the most restrictive approach to outgoing prisoner correspondence. Invoking the “rehabilitation” moniker does not magically make censorship constitutional. 16 GRENNING V. KEY of Grenning’s writing was a literary journal does not alter the analysis. The argument that “a screening requirement” for outgoing inmate mail does not regulate inmate speech runs smack into the teaching of Martinez. The rights protected by the First Amendment may not be “renamed away” or have their “protections nullified by mere labels.” Chiles v. Salazar, 146 S. Ct. 1010, 1021 (2026) (citation modified). The government cannot refuse to externally transmit a short story to a literary journal because it contains a passing reference to sexual intimacy and call that refusal “screening,” “prescreening,” or an unspecified “prison approval” rule. Call it what you want, the refusal was content-based, pure and simple. The government cannot foil a First Amendment claim with a thesaurus. Viewed in the light most favorable to Grenning as the nonmovant, Dodge, 56 F.4th at 773, the record bespeaks genuine issues of material fact that relate to the alleged constitutional violation. Those facts relate to the claimed policy governing Grenning’s submission, the extent and nature of the procedural safeguards that the policy provided to inmate submissions, whether Grenning’s attempt to submit “Dark Room” to InRoads violated that policy, the reasons why Wise decided to bar the story and Key supported that decision, and the availability of alternatives such as editing the contested sentence out of the story. Those issues render summary judgment inappropriate. Id. In light of Martinez, we conclude that Grenning had a clearly established right not to have Key and Wise refuse to transmit his nonthreatening outgoing written expression because they disapproved of its content or feared the public’s reaction to it, unless they could establish a sufficiently GRENNING V. KEY 17 “close[] fit,” Thornburgh, 490 U.S. at 412, between that restriction and “one or more of the substantial governmental interests of security, order, and rehabilitation,” Martinez, 416 U.S. at 413, in a way that was “unrelated to the suppression of expression,” id. at 413, and as long as the restriction’s “sweep” was not “unnecessarily broad,” id. at 414. As the discussion of the similarities between Martinez and Grenning’s case demonstrates, supra pp. 13–14, Martinez and its progeny “placed the . . . constitutional question beyond debate.” White v. Pauly, 580 U.S. 73, 79 (2017) (citation omitted). Supreme Court precedent made “the contours of the right sufficiently clear” such that “every reasonable official would have understood that what he is doing violates that right.’” Ashcroft v. al-Kidd, 563 U.S. 731, 741 (2011) (citation modified). Put differently, because the gravamen of the inquiry is “fair warning” and “fair notice,” Hope v. Pelzer, 536 U.S. 730, 741–42 (2002), Grenning need not point us to “a case directly on point.” Al-Kidd, 563 U.S. at 741. But with Martinez, he has certainly come as close as possible. The Department of Corrections policy made the same rule concrete for Key and Wise. The policy allowed inspection and reading of mail to prevent contraband, threats to “facility order or security,” and criminal activity and expressly explained that mail rejection would be based on “legitimate penological interests.” The policy also contemplated that “the contents” of an inmate’s mail that left the prison would be “uncensored,” and provided that only publications with “sexually explicit material” such as the act described in “Dark Room” would need to “contain significant or repeated instances” of prurient content to be subject to rejection. While the policy does not itself clearly 18 GRENNING V. KEY establish a constitutional right, it nonetheless remains “relevant . . . to whether reasonable officers would have been on notice that” their conduct violated the First Amendment. Drummond ex rel. Drummond v. City of Anaheim, 343 F.3d 1052, 1062 (9th Cir. 2003). The backdrop of the Supreme Court’s jurisprudence regarding content-based regulations of speech serves to explain our conclusion. It is well established that “above all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content.” Police Dep’t of City of Chicago v. Mosley, 408 U.S. 92, 95 (1972). In view of “the First Amendment’s jealous protections for the individual’s right to think and speak freely,” the Court has “long held that [state action] regulating speech based on its subject matter or ‘communicative content’ [is] ‘presumptively unconstitutional.’” Chiles, 146 S. Ct. at 1021 (citation omitted). 4 While the shape of the doctrine has changed considerably since the Founding, “a demand that the government act neutrally with respect to the content of the speech it regulates . . . has been a feature of free-speech law in the United States since the eighteenth century.” 4 Prison writings have an equally storied past. See, e.g., Boethius, The Consolation of Philosophy (Victor Watts trans., Penguin Classics rev. ed. 1999) (philosophical work written while Boethius was imprisoned and awaiting execution for treason in the sixth century); The Forlorn Hope, Mar. 24, 1800 (newspaper written and published by inmates in a New York debtors’ prison); Oscar Wilde, De Profundis and Other Prison Writings (Colm Tóibín ed., Penguin Classics 2000) (1905) (letter written during Wilde’s imprisonment for gross indecency at Reading Gaol); Martin Luther King, Jr., Letter from Birmingham Jail (Apr. 16, 1963), University of Alabama Libraries Special Collections, https://perma.cc/5N7J-FCXN (letter written during King’s Birmingham confinement in response to criticism of the civil rights movement). GRENNING V. KEY 19 Genevieve Lakier, A Counter-History of First Amendment Neutrality, 131 Yale L.J. Forum 873, 875 (2022). That presumption generally means that “content-based restrictions trigger strict scrutiny.” Chiles, 146 S. Ct. at 1021 (citation modified). The Court’s decision in Martinez brought inmate mail into the First Amendment’s analysis of content-based speech restrictions. To be sure, the protections of the First Amendment must be “applied in light of the special characteristics” of the environment. Tinker v. Des Moines Indep. Cmty. Sch. Dist., 393 U.S. 503, 506 (1969). In the prison context, the Court has applied those protections with an effort to give “due regard [to] the ‘inordinately difficult undertaking’ that is modern prison administration.” Thornburgh, 490 U.S. at 407 (quoting Turner, 482 U.S. at 85). For a large part of their history, however, the federal courts “adopted a broad hands-off attitude toward problems of prison administration,” including regulations on prisoner speech. Martinez, 416 U.S. at 403. That attitude reflected a notion that the prisoner was “the slave of the State.” Ruffin v. Commonwealth, 62 Va. (21 Gratt.) 790, 796 (1871). As that understanding began to evolve in the lower courts, see, e.g., Weller v. Dickson, 314 F.2d 598, 599–601 (9th Cir. 1963) (a prisoner could bring an “action[] for damages under the Civil Rights Act, 42 U.S.C. §§ 1981–1988, against various officials of the State of California”), the Supreme Court recognized a state prisoner’s right to sue prison officials under Section 1983 for First Amendment violations in Cooper v. Pate, 378 U.S. 546 (1964) (per curiam). The Court’s decision in Martinez came a decade later and recognized that “a policy of judicial restraint” with respect to prison administration “cannot encompass any failure to 20 GRENNING V. KEY take cognizance of valid constitutional claims.” Martinez, 416 U.S. at 405. Following Martinez, the Court in Turner articulated a more deferential reasonableness test for ordinary prison regulations. See 482 U.S. at 90. The Court subsequently, in Thornburgh, applied the Turner standard to incoming publications while preserving the Martinez heightened standard for outgoing correspondence. 490 U.S. at 412–13. The Court recognized both that outgoing correspondence was Martinez’s “central focus” and that “the implications of outgoing correspondence for prison security are of a categorically lesser magnitude than the implications of incoming materials.” Thornburgh, 490 U.S. at 412–13. More recently, the Court applied Turner to inmate-to-inmate legal correspondence and declined to recognize heightened protection “above and beyond the protection normally accorded prisoners’ speech” in that context, Shaw v. Murphy, 532 U.S. 223, 231 (2001), but “did not address the right of prisoners to send mail outside the prison—the regulation of which is governed by the Martinez standard.” Koutnik v. Brown, 456 F.3d 777, 784 n.4 (7th Cir. 2006). Each time the Court has considered the scope of Martinez, it has preserved the application of that standard to outgoing inmate correspondence, while also reaffirming the principle that incarceration does not send the inmate into a void beyond the Constitution’s reach. We too have reaffirmed that regulation of outgoing inmate correspondence sits squarely in Martinez’s domain. See Barrett, 544 F.3d at 1062 (“Procunier [v. Martinez] is controlling law in the Ninth Circuit and elsewhere as applied to claims involving outgoing prisoner mail.”); Lane v. Salazar, 911 F.3d 942, 945, 948–50 (9th Cir. 2018) (applying Martinez to discipline for statements in outgoing GRENNING V. KEY 21 letters and holding that threats of bodily harm “address[] legitimate penological concerns in a manner that is sufficiently narrow to satisfy constitutional concerns”); Lane v. Swain, 910 F.3d 1293, 1294, 1297 (9th Cir. 2018) (holding that Federal Bureau of Prisons Prohibited Acts Code 203, which bars “[t]hreatening another with bodily harm or any other offense” constitutes “a sufficiently ‘close fit’ with [the asserted] legitimate interests to pass the Procunier [v. Martinez] test”); Witherow v. Paff, 52 F.3d 264, 265 (9th Cir. 1995) (per curiam) (“When a prison regulation affects outgoing mail as opposed to incoming mail, there must be a ‘closer fit between the regulation and the purpose it serves.’” (quoting Thornburgh, 490 U.S. at 412)). We have, by contrast, applied Turner to assess “the constitutionality of prison rules that restrict the ingress and possession of sexually explicit materials.” Prison Legal News v. Ryan, 39 F.4th 1121, 1129 (9th Cir. 2022) (emphasis added). Other circuits similarly continue to distinguish between outgoing and incoming prisoner correspondence. See Nasir v. Morgan, 350 F.3d 366, 371 (3d Cir. 2003) (“Because Thornburgh holds that Turner does not squarely overrule Martinez as applied to outgoing mail, we will apply Turner to incoming mail and Martinez to outgoing correspondence.”); see also Brooks v. Andolina, 826 F.2d 1266, 1268–69 (3d Cir. 1987) (“The Turner opinion . . . provides no support” where the prisoner was “not disciplined for communicating with other inmates, but for the contents of his letter to a person outside the prison system,” because if officials “cannot censor unflattering statements made in letters to outsiders, they also may not punish an inmate for the contents of such letters.”); Loggins v. Delo, 999 F.2d 364, 366–68 (8th Cir. 1993) (inmate’s letter containing 22 GRENNING V. KEY “derogatory comments” about mailroom clerk did not “implicate [prison] security concerns” and thus the disciplining of the inmate was unconstitutional under Martinez); McNamara v. Moody, 606 F.2d 621, 624 (5th Cir. 1979) (“No [governmental] interest is implicated by the mailing of non-erotic vulgarities from a prisoner to a person on the outside,” and if a “warden’s purpose [was] to prevent strongly worded and exaggerated criticism of prison officials from reaching the public,” that was “precisely the sort of purpose ruled impermissible by Martinez”). Unlike the dissent, we are persuaded by the weight of this authority that Martinez established an enduring “governing standard” that applies in this instance. Dissent at 33. While the domain of the Martinez rule has narrowed, its core—regulations that govern inmates’ outgoing correspondence—remains intact. We finally note that we would be compelled to reverse even if we agreed with the view that Turner applies in this circumstance. We have articulated the Turner factors as follows: (1) [W]hether there is a valid, rational connection between the policy and the legitimate governmental interest put forward to justify it; (2) whether there are alternative means of exercising the right; (3) whether the impact of accommodating the asserted constitutional right will have a significant negative impact on prison guards, other inmates and the allocation of prison resources generally; and (4) whether the policy is an GRENNING V. KEY 23 “exaggerated response” to the [prison]’s concerns. Mauro v. Arpaio, 188 F.3d 1054, 1058–59 (9th Cir. 1999) (en banc) (quoting Turner, 482 U.S. at 89–90). The suppression of Grenning’s story founders on the first Turner factor, which is “a sine qua non” of the analysis. Walker v. Sumner, 917 F.2d 382, 385 (9th Cir. 1990). In our examination of that factor, we “determine whether the governmental objective underlying the policy is (1) legitimate, (2) neutral, and (3) whether the policy is ‘rationally related to that objective.’” Mauro, 188 F.3d at 1059 (quoting Thornburgh, 490 U.S. at 414). On this score, although the Turner test is deferential, it “does not make the First Amendment ‘toothless.’” Prison Legal News, 39 F.4th at 1129 (quoting Thornburgh, 490 U.S. at 414). We have previously applied Turner to deem unconstitutional bans on incoming publications “that may, could reasonably be anticipated to, could reasonably result in, [are,] or appear[] to be intended to cause or encourage sexual excitement or arousal or hostile behaviors, or that depict[] sexually suggestive settings, poses or attire.” Id. at 1133. In this case, Key’s claimed goal of preventing negative publicity obviously would n
