Christopher Lekas, a prisoner in the custody of the Illinois Department of Corrections (IDOC), makes several constitutional claims relating to his placement and confinement in disciplinary segregation. The district court dismissed his complaint for failure to state a claim. We affirm this dismissal because we find that the allegations of Lekas’s complaint effectively plead him out of court by detailing conditions that do not amount to a deprivation of a liberty interest, and because he failed to present arguments before the district court linking the allegations of retaliation in his complaint to his Section 1983 claim, leaving him with no case or controversy upon which to base a constitutional challenge of Section 1997e(e) of the Prison Litigation Reform Act of 1995 (codified at 42 U.S.C. § 1997e(e)).
I. BACKGROUND
In reviewing a district court’s dismissal of a complaint under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim, we “take the plaintiffs factual allegations as true and draw all reasonable inferences in his favor.”
DeWalt v. Carter,
In early November of 2000, while still incarcerated at Menard, Lekas mailed Murray a package containing two ceramic mugs and a personal letter via a third party. Under the IDOC’s Rule against “Abuse of Privileges” (Rule 310), inmates are prohibited from “corresponding or communicating with a ... person after the committed person has received notice that such person has informed the [IDOC] that he or she does not wish to receive correspondence from the committed person.” Ill. Admin. Code tit. 20, § 504, Table A. There is, however, no rule against inmates sending mail or gifts to an IDOC facility employee.
Soon after he had mailed his package to Murray, on November 9, 2000, a disciplinary report was issued, stating that Lekas was “being placed on investigative status for his possible involvement in sending unauthorized correspondence.” 1 That same day, Lekas was transferred to State-ville Correctional Center, where he was placed in the segregation unit under “investigative status.” Lekas was not informed as to the precise basis for his reclassification to “investigative status” until November 17, 2000. At that time, an investigator for the IDOC informed him that he was being questioned regarding the package he sent to Murray. In response to the investigator’s questions, Le-kas explained that Murray had given him her address, a photograph of herself with . her child, and permission to correspond with her. Notwithstanding his explanation, a disciplinary report was issued from Pinckneyville on December 8, 2000, officially charging Lekas with violation of IDOC Rules against “Abuse of Privileges” (Rule 310) and “Dangerous Communications” (Rule 208). 2
A hearing on these charges was held before the Adjustment Committee at Stateville on December 13, 2000. In response to the Abuse of Privileges charge, Lekas again asserted that Murray had permitted and encouraged his correspondence, and had not, as an “Abuse of Privileges” violation would require, given notice that his correspondence was unwelcome. Furthermore, his custodians proffered no evidence that would suggest that Murray gave such notice, as was their burden to establish the charge. Notwithstanding this alleged lack of evidence, the Adjustment Committee, composed of defendants Carol DelPriore, Daniel Luce, and Michael Dangerfield, found Lekas guilty of Abuse of Privileges, and sentenced him to three months of segregation, demoted him to “C Grade” for three months, and denied him commissary privileges for three months. The committee did, however, find Lekas not guilty of the “Dangerous Communications” charge.
Lekas then pursued an administrative appeal by filing a grievance before the *605 ARB, asserting, inter alia, that the process of his disciplinary proceedings had violated his civil rights. But that grievance also failed, and allegedly resulted in its own, independent violations of department rules on grievance proceedings. 3
When all was said and done, Lekas had served about 90 days in segregated confinement — from November 9, 2000 until approximately February 9, 2001. While in segregation, he was unable to participate in prison programs, educational programs, and work programs; he lost prison employment, wages, contact visits, telephone privileges, visits from clergy, and access to church; and he ,was allowed fewer visits from family, exercise privileges, commissary privileges, personal possessions, and audio/visual items. According to his complaint, these conditions were “significantly atypical” from those in the general prison population.
Lekas, proceeding
pro se,
filed a Section 1983 claim in federal district court, alleging that several of his custodians violated his due process rights by depriving him of a liberty interest created by Illinois law when they placed him in segregation in contravention of the department’s own rules. The district court immediately dismissed the complaint
sua sponte,
pursuant to 28 U.S.C. § 1915(e)(2)(B), for failure to state a claim upon which relief could be granted, reasoning that this Circuit had already found in cases such as
Williams v. Ramos,
The Second Amended Complaint states two claims for relief. Count I, brought pursuant to 42 ]J.S.C. § 1983, alleges that the various prison employees named above, as well as defendant Kenneth Briley (the Chief Administrative Officer of Stateville) — together, “State Defendants” — violated his constitutional right to procedural due process by placing him in disciplinary segregation in contravention of their own mandatory department rules, and without evidence supporting the elements of the charge that would warrant his segregation. Count II joins the U.S. Attorney General (“Federal Defendant”) seeking a declaratory judgment that Section 1997e(e) of the Prison Litigation Reform Act of 1995 is unconstitutional both facially and as applied to the facts of this case. This second count asserts that Section 1997e(e) deprives prisoners of due process and denies them equal protection by leaving them without remedy for constitutional deprivations resulting in solely non-physical injuries.
The district court, however, dismissed this Second Amended Complaint upon motions by both State and Federal Defendants under Federal Rule of Civil Procedure 12(b)(6). In particular; the court found that Count I failed to state a claim because Lekas’s segregation as alleged did *606 not amount to a deprivation of a liberty-interest and therefore could not form the basis of a procedural due process claim. With respect to Count II, the court found Lekas’s Section 1997e(e) challenge “untenable,” concluding that the provision was “merely a limitation on recovery,” and not — as the complaint alleged — an outright bar. Lekas appeals.
II. ANALYSIS
A complaint may be dismissed under Rule 12(b)(6) for “failure to state a claim upon which relief can be granted.” Accordingly, a complaint’s ability to survive a Rule 12(b)(6) challenge inevitably turns on its ability to satisfy Rule 8 of the Federal Rules of Civil Procedure — the general rules of pleading a claim for relief. Under Federal Rule of Civil Procedure 8(a)(2), plaintiffs complaint need only contain “a short and plain statement of the claim showing that the pleader is entitled to relief.” This “short and plain statement,” with irrelevant exceptions, requires the plaintiff to plead merely “the bare minimum facts necessary to put the defendant on notice of the claim so that he can file an answer,”
Higgs v. Carver,
Within this liberal framework of notice pleading, Lekas seeks to state a claim against State Defendants under 42 U.S.C. § 1983. “In order to state a claim under Section 1983, a plaintiff must allege that the defendants deprived him of a right secured by the Constitution or laws of the United States, and that the defendants acted under color of state law.”
Brokaw v. Mercer County,
Lekas argues that his due process rights were violated because he was placed in disciplinary segregation without any evidence to support the key elements of the infraction of which he was charged, and because the IDOC failed to follow its own mandatory departmental rules for conducting his discipline hearing and administrative review. However, before wrestling with the contours and nuances of the process allegedly rendered or withheld, we must first determine whether any process was in fact constitutionally due.
*607
The Due Process Clause of the Fourteenth Amendment provides: “[N]or shall any State deprive any person of life, liberty, or property, without due process of law.” U.S. CONST, amend. XIV, § 1. Accordingly, the procedural protections of the Due Process Clause will only be triggered if state action implicates a constitutionally protected interest in life, liberty, or property.
Bd. of Regents of State Colleges v. Roth,
Here, the alleged deprivation to Lekas was his placement in disciplinary segregation-—-purportedly in contravention of a liberty interest. “The Due Process Clause,” however, “does not necessarily protect prisoners against the imposition of disciplinary segregation..”
Williams v. Ramos,
But here Lekas does not merely object to his placement in disciplinary segregation, but rather his placement there in contravention of the IDOC’s own mandatory rules and regulations. Indeed, prior to the Supreme Court’s ruling in
Sandin v. Conner,
statutory or regulatory “language of an ... unmistakably mandatory character”—such as that provided by IDOC rules and regulations-—was recognized as creating a liberty interest protected by the Due Process Clause.
Hewitt,
Now much hinges upon what constitutes an “atypical and significant hardship,” and the
Sandin
Court again provides guidance. In finding that the placement of the plaintiff-prisoner in disciplinary segregation for thirty days did not constitute an “atypical and significant hardship,” the
Sandin
Court relied upon three factors. First, the prisoner’s “disciplinary segregation, with insignificant exceptions, mirrored those conditions imposed upon inmates in administrative segregation and protective custody.”
Sandin,
There remains, however, some doubt as to how courts should weigh these three factors. Certainly, the third factor — prolonging the prisoner’s incarceration — persists as both a universally accepted and readily ascertainable basis for a due process claim in this area.
Wagner v. Hanks,
Sandin’s prescribed comparison between disciplinary segregation and the general prison population seems inevitably subsumed by its prescribed comparison be
*609
tween disciplinary segregation and discretionary segregation. This is because, in every state’s prison system, any member of the general prison population is subject, without remedy, to assignment to administrative segregation or protective custody at the sole discretion of prison officials,
Wagner,
128
F.3d
at 1176 (“[E]ven a prisoner who had committed a white-collar crime and had been assigned to the lowest-security prison in the state’s system might find himself in segregation for a nondisciplinary reason.”);
see also Hewitt,
Indeed, taking Sandin’s prescribed comparisons to their logical extremes, it is possible that the conditions of discretionary segregation against which the plaintiffs confinement is to be judged are not necessarily those of the prison in which the plaintiff is incarcerated, but rather those of the most restrictive prison in the state penal system,
Wagner v. Hanks,
Suffice it to say, “when the entire sanction is confinement in disciplinary segregation for a period that does not exceed the remaining term of the prisoner’s incarceration, it is difficult to see how after
Scmdin
it can be made the basis of a suit complaining about a deprivation of liberty.”
Wagner,
Here, Lekas attempts to plead a deprivation of a liberty interest — ie., an atypical and significant hardship — by alleging the following:
The conditions to which Plaintiff was subjected while in segregation at State-ville from November 9, 2000 until approximately February 9, 2001 differed markedly and appreciably from, and were significantly atypical from, those of the general prison population, including but not limited to: inability to participate in prison programs, inability to participate in educational programs, inability to participate in work programs and resulting loss of prison employment and wages, loss of contact visits, loss of telephone usage, inability or substantially curtailed ability to receive visits from family, inability to attend church, no visits from clergy, drastic reduction in exercise privileges and in commissary access both in terms of frequency and the types of items allowed, drastic reduction in the number and nature of personal items that prisoners are allowed to have in their possession, and no access or very little access to audio/visual items.
Second Amended Complaint ¶ 31.
This court has twice before had the opportunity to compare conditions of disciplinary segregation to those of discretionary segregation at Lekas’s prison (Stateville), on both occasions holding that the conditions of disciplinary segregation there were not so atypical and significant as to constitute a deprivation of a liberty interest.
Williams v. Ramos,
In
Thomas,
the plaintiff-prisoner (Thomas) was subjected to 24 hour a day segregation
5
for 70 days in a locked cell.
Thomas,
Notwithstanding the litany of deprivations set forth in
Williams
and
Thomas,
this court in both cases, employing both
Sandin
prescribed comparisons, found that the conditions of Stateville disciplinary segregation were not actionably different from those in either the general prison population,
Thomas,
However, the fact that the conditions of disciplinary segregation at Stateville were found over seven to ten years ago not to work a deprivation of a liberty interest alone does not warrant the dismissal of Lekas’s claim. Indeed, recognition of this fact led the district court to reinstate Lekas’s case. Within the spacious universe of possibilities at this stage of the litigation, limited only by a court’s ability to hypothesize reasonably facts consistent with the allegations of the complaint,
San-ville v. McCaughtry,
A comparison of our past rulings on the conditions of disciplinary segregation at Stateville to those conditions alleged in the case at bar, however, suggests that little, if anything, has changed in the prison’s administration of disciplinary segregation over the past seven to ten years. While Lekas insists that those conditions have deteriorated since our pronouncements in
Williams
and
Thomas,
his own complaint betrays his argument. Lekas’s complaint alleges in painstaking detail the
*612
deprivations he has putatively endured— deprivations virtually indistinguishable from those found in
Williams
and
Thomas,
save for the duration of his punishment.
6
But while Lekas’s 90 day segregation was longer than the 19 day confinement in
Williams
and even the 70 day segregation in
Thomas,
it was still not so long as to work an atypical and significant hardship.
Whitford v. Boglino,
We note, however, that the complaint’s catalogue of deprivations is non-exhaus-five. Second Amended Complaint ¶ 31 (listing hardships “including, but not limited to,” those set forth therein). This hedging by Lekas precludes the court from dismissing his claim solely on the basis of his prolix recitation of hardships.
American Nurses’ Association v. Illinois,
A plain reading of Lekas’s complaint compels us to conclude that the conditions of disciplinary segregation at Stateville do not differ in the slightest from those in discretionary segregation. The many deprivations Lekas is alleged to have endured occurred during his placement in what he generically refers to as “segregation at Stateville from November 9, 2000 until approximately February 9, 2001.” Second Amended Complaint ¶ 31. While this blanket reference alone suggests that Lekas was subjected to only one classification of segregation without distinction during the 90 day span between November 9, 2000 and February 9, 2001, a closer examination of his complaint reveals otherwise.
*613
According to his complaint, Lekas was “placed in the segregation unit and classified under investigative status” on November 9, 2000. Second Amended Complaint ¶ 30. By December 8, 2000, he was “ordered [to] continue ... in ‘Temporary Confinement’ ” while awaiting a hearing on the offense with which he was charged. Second Amended Complaint ¶ 38. “Both temporary confinement and investigative status,” however, “have been determined to be
discretionary segregation,
and do not implicate a liberty interest.”
Thomas,
Despite this reclassification from discretionary to disciplinary segregation on December 13, Lekas does not allege any change in the conditions of his confinement commensurate with that reclassification. Indeed, by failing to even distinguish between the two — opting instead to lump them both together under the single rubric of “segregation” — his complaint avers that the conditions and commensurate hardships of both were in fact identical. By averring identical conditions in both disciplinary and discretionary segregation, Le-kas’s complaint itself suggests, in the very least, that the conditions of his confinement did not materially change upon his assignment to disciplinary segregation. Certainly, a comparison of the conditions of discretionary and disciplinary segregation as alleged in the complaint cannot yield a hardship so atypical and significant as to deprive Lekas of a liberty interest.
See Wagner v. Hanks,
Thus, the fatal deficiency in Lekas’s complaint is not that it alleges too little, but that it alleges too much. Indeed, no more than an allegation of a “loss of liberty” is required to satisfy the requirements of notice pleading under the Federal Rules of Civil Procedure.
Wagner,
We briefly address Lekas’s Section 1983 retaliation claim. “An act taken in retaliation for the exercise of a constitutionally protected right is actionable under § 1983 even if the act, when taken for a different reason, would have been proper.”
Matzker v. Herr,
Lekas, however, has waived his retaliation claim. “[WJhat is fatal to [a] theory on appeal is [plaintiffs] failure to mention it to the district court when the time did come in the proceedings below to present legal arguments linking the claims described in the complaint to the relevant statutory (or other) sources for relief.”
Teumer v. General Motors Corp.,
Finally, because we affirm the dismissal of Lekas’s Section 1983 due process claim and recognize the waiver of his Section 1983 retaliation claim, no “case or controversy” remains between these parties. In the absence of an actual controversy, this court remains both constitutionally and statutorily constrained from reaching Le-kas’s second count seeking a declaratory judgment that Section 1997e(e) of the Prison Litigation Reform Act of 1995 (codified at 42 U.S.C. § 1997e(e)) is unconstitutional.
See Deveraux v. City of Chicago,
III. CONCLUSION
For the reasons stated above, we AffiRM the district court’s dismissal of Lekas’s claims against both state and federal defendants.
Notes
. This disciplinary report was issued by defendant C.T. Caraway (an employee at Menard) and approved by defendants Joe Cowan (a Menard employee signing as "Shift Supervisor") and Anthony Ramos (a Menard Correctional Officer signing as "Reviewing Officer”).
. This second disciplinary report was issued by defendant Tim Laird (a Correctional Lieutenant in Internal Affairs) and approved by defendants Michael Chapman (a Pinckneyville employee acting as "Shift Supervisor”), Theopolas Smith (a Pinckneyville employee acting as "Reviewing Officer”), and P. Brooks (a Pinckneyville employee acting as "Hearing Investigator”).
. Lekas alleges that the Chairman of the ARB (defendant Robert Radmacher) violated IDOC Rule 850(e) and (f) (codified at Ill. Admin.Code tit. 20, § 504, Table A), which require that all ARB decisions be reviewed and approved by the IDOC. Director (here, defendant Donald N. Snyder, Jr.), by reviewing and concurring with his own decision by signing the Director’s name to the report. Lekas lodged a grievance regarding this practice by Radmacher, but ultimately this complaint, too, was denied.
. The term "discretionary segregation” — encompassing both administrative segregation and protective custody — refers to "single-person cells in which persons are sometimes confined not because they have misbehaved but simply because the prison has no other space, wishes to protect some prisoners from others, wishes to keep prisoners isolated from one another in order to minimize the risks of riots or other disturbances, wishes to prevent the spread of disease, and so forth.”
Wagner v. Hanks,
. Unlike Lekas, who was allegedly placed in solitary confinement, the plaintiff-prisoner in
Thomas
was confined with another inmate. However, that assignment in
Thomas
presented a different, perhaps more onerous, hardship, in that two inmates were forced to share a cell “approximately as wide as [the plaintiff's] out-stretched arms and twice that long.”
Thomas,
. Lekas’s counsel at oral argument placed great emphasis on the fact that the plaintiffs in both
Sandin
and
Williams
had, unlike Le-kas, voluntarily requested placement in segregation prior to the segregation of which they ultimately and respectively complained. While such requests can serve as evidence that the hardships of segregation are neither atypical nor significant, "we do not think a prisoner’s subjective expectation is dispositive of the liberty interest analysis.”
Sandin v. Conner,
. Furthermore, for the first 34 days of his confinement, Lekas was being held under investigative status and temporary confinement, not disciplinary segregation. Second Amended Complaint at ¶¶ 30, 38, 45, 48. Because ”[b]oth temporary confinement and investigative status have been determined to be discretionary segregation, and do not implicate a liberty interest,” Thomas, 130 F.3d at761, the net duration of Lekas's disciplinary segregation was only about 56 days — falling well short of an atypical and significant term of punishment.
. In response to the defendants’ motion to dismiss, Lekas merely makes passing reference to retaliatory motives on the part of prison officials. This brief states that he "believes and so alleges that the real reason for the investigative report was retaliation for previously filed grievances”; that "the Constitutional deprivation was, in part, due to retaliation for prior claims and grievances he had filed”; and that his placement in segregation was "based on flawed procedures and retaliatory conduct.” Response to Defendants’ Motion to Dismiss at 2, 14, 15. These statements alone — made without any reference to relevant legal authority, and strewn about in his brief in the context of defending other, well-articulated claims — do not suffice to mount a legal argument that would alert the district court to the ostensible merits of a separate Section 1983 retaliation claim.
In the alternative, Lekas contends that defendants in their motion to dismiss did not challenge the retaliation claim, and that he was therefore not obliged at that stage to *615 defend it against their Rule 12(b)(6) challenge. Even accepting plaintiffs argument, it is inescapable that the district court in granting defendants' motion to dismiss dismissed all claims brought by Lekas. If Lekas believed the district court had dismissed an unchallenged retaliation claim in error, then the burden was on him to salvage that claim through a Motion to Amend or Alter Judgment pursuant to Federal Rule of Civil Procedure 59(e). While Lekas did file such a motion under Rule 59(e), neither the word 'retaliation” nor any derivation thereof can be found therein.
