“Force Only as a Last Resort” Prison Use-of-Force Rules Are Not Unconstitutionally Vague as Applied to Officers

I. Introduction

In Derek Hundley v. Dee Dee Brookhart, the U.S. Court of Appeals for the Seventh Circuit addressed whether Illinois Department of Corrections (“Department”) use-of-force rules—requiring that force be used “only as a last resort”— were unconstitutionally vague as applied to correctional officers who were terminated following a cell-extraction incident.

The plaintiffs-appellants, Correctional Lieutenant Derek Hundley and officers Robert Kamp and Travis Ochs, were discharged after the Illinois Civil Service Commission (“Commission”) concluded they violated Department rules by opting for force too early during an incident involving a wheelchair-dependent inmate, Deandre Bradley, and by filing reports that did not disclose that Bradley had been dragged (describing him instead as “escorted”). The officers sued under 42 U.S.C. §1983, alleging that their terminations violated the Fourteenth Amendment’s Due Process Clause because the “force as last resort” standard did not provide fair notice of what conduct was prohibited.

The district court granted summary judgment for defendants, holding the rules were not unconstitutionally vague; the Seventh Circuit affirmed.

II. Summary of the Opinion

The Seventh Circuit held that the Department’s “force shall be employed only as a last resort” rule, as codified in 20 Ill. Admin. Code §501.30(a) (and echoed in Dep’t Admin. Directive 05.01.173), was not unconstitutionally vague as applied to these officers. The court emphasized that “last resort” is plain language meaning “try all other reasonable methods first,” and that public-employee conduct rules—especially in the prison setting—receive wider constitutional latitude.

The court further held that the officers’ attempt to contest the “false incident reports” basis for discipline failed because that claim was not pleaded in the complaint; and in any event, the truthful-reporting requirements were themselves clear. Because the vagueness challenge failed, the court did not reach qualified immunity and affirmed summary judgment.

III. Analysis

A. Precedents Cited

1. Vagueness doctrine baseline: Grayned v. City of Rockford

The court anchored the analysis in Grayned v. City of Rockford, 408 U.S. 104 (1972), which states that a law is not void for vagueness if it gives a person of ordinary intelligence a reasonable opportunity to know what is prohibited. The Seventh Circuit used Grayned to set the constitutional floor: mathematical precision is unnecessary; fair notice is the touchstone.

2. Enhanced latitude for public-employee codes: Hicks v. Illinois Dep't of Corr. and Greer v. Amesqua

The opinion relied heavily on Hicks v. Illinois Dep't of Corr., 109 F.4th 895 (7th Cir. 2024), which recognizes that when the government regulates employee conduct (rather than the public), it has “even wider latitude.” Quoting Greer v. Amesqua, 212 F.3d 358 (7th Cir. 2000), the court reiterated the operative standard: employee discipline rules are impermissibly vague only if they fail to “convey adequate warning” to “reasonable employees” of a “sufficiently defined range of inappropriate conduct.”

Hicks also supplied a prison-specific gloss: because of “unique safety and security concerns,” prison employers get “more latitude” in discipline decisions and personnel regulations than ordinary government employers. That principle materially influenced the court’s unwillingness to constitutionalize disputes about whether alternative tactics might have been preferable.

3. Scope of appellate review and “not a super-personnel department”: Russell v. Comstock, Raddant v. Douglas Cnty., Wis., and Wilson v. AIM Specialty Health

The panel cited Russell v. Comstock, 167 F.4th 984 (7th Cir. 2026), for de novo review of summary judgment. It cited Raddant v. Douglas Cnty., Wis., 170 F.4th 583 (7th Cir. 2026), to emphasize that, at summary judgment, the court assumes the plaintiffs’ factual account (e.g., inmate belligerence) is true.

Although Wilson v. AIM Specialty Health, No. 23-3418, 2026 WL 1481216 (7th Cir. May 27, 2026), is an employment case, it was invoked for an institutional point: federal courts are not “super-personnel department[s]” second-guessing discipline decisions. The court used this principle to narrow the inquiry to the constitutional vagueness question and to reject invitations to adjudicate tactical wisdom.

4. Pleading and notice: Bell Atl. Corp. v. Twombly and Conley v. Gibson

On the “false report” issue, the court cited Bell Atl. Corp. v. Twombly, 550 U.S. 544 (2007), quoting Conley v. Gibson, 355 U.S. 41 (1957), for the requirement that a complaint provide fair notice of what the claim is and the grounds upon which it rests. The officers’ complaint challenged only the use-of-force rules as vague; it did not challenge the truthful-reporting rules. The precedents supported the conclusion that plaintiffs could not effectively add a new theory in summary-judgment briefing.

B. Legal Reasoning

1. Framing: as-applied vagueness in an employee/prison context

The officers explicitly pursued an as-applied vagueness challenge. That posture mattered: the court did not ask whether “last resort” could ever be unclear at the margins, but whether it was unclear for these officers in these circumstances. The court found the officers never explained what made their situation uniquely difficult to understand under the rule’s plain language.

2. The operative rule and why “last resort” was deemed sufficiently clear

The “keystone rule” provides: “[f]orce shall be employed only as a last resort or when other means are unavailable or inadequate and only to the degree reasonably necessary to achieve a permitted purpose.” 20 Ill. Admin. Code §501.30(a). “Force” is defined broadly as “physical contact used to coerce or prevent some action ... and the use of chemical agents.” 20 Ill. Admin. Code §501.20(a).

The court reasoned that “last resort” “very clearly means ‘try all other reasonable methods first.’” The officers need not have been on notice of a single mandated alternative step (e.g., calling a supervisor or the tactical team), because the rule does not require a particular checklist; it requires that force not be chosen while other reasonable means remain available. The record evidence that they had time (20–60 minutes) and options supported the Commission’s conclusion that they acted prematurely.

3. Not at the margins: the court’s “one resort” point

The court rejected the suggestion that repeated commands alone satisfied “last resort.” It characterized the officers’ approach as multiple iterations of the same tactic—ordering Bradley to comply—amounting to “one resort,” followed quickly by a use-of-force plan: five officers entering the cell intending to remove handcuffs by attaching a “lead chain” and pulling Bradley’s arms into the cuffing port. Because there was “no evidence of an imminent threat to any person or property,” the court viewed this as a straightforward, non-borderline application of the rule.

4. Interaction with “lawful order” force authorization: 20 Ill. Admin. Code §501.40(a)(1)

The officers invoked language allowing force to compel compliance with a lawful order. The court reconciled the provisions by reading §501.40(a)(1) as subordinate to the overarching “last resort” limitation in the immediately preceding subsection of the “Resort to Force” subpart. Otherwise, the court reasoned, the lawful-order authorization would “swallow the rule,” effectively permitting maximal force for minor refusals—an outcome inconsistent with the regulatory structure and prison force-limitation objectives.

5. When “force” begins: entering the cell with an intended physical-coercion plan

The panel rejected the argument that force began only after Bradley escalated (e.g., throwing a catheter bag). Under the regulatory definition, the court treated the officers’ planned physical coercion to remove handcuffs as “force,” and it accepted testimony that the anti-force-last-resort directive “applies once officers enter a cell before exhausting other options.” The court emphasized the policy purpose: limiting force is meant to prevent escalation; deciding on force too early can itself foreclose de-escalation opportunities.

6. Truthfulness reports: not pleaded, and clear in any event

The court held the plaintiffs did not properly present a separate due process vagueness challenge to the truthful-reporting rules because the complaint did not mention them. On the merits (in the alternative), it stated that rules requiring complete and accurate unusual-incident documentation and warning that false information can result in termination are not vague: 20 Ill. Admin. Code §112.30(a), 20 Ill. Admin. Code §120.95, and Dep't Admin. Directive 01.12.120. The record lacked evidence that anyone instructed the officers to use “escort” rather than “drag.”

7. Qualified immunity avoided

Because the court found no constitutional violation (no vagueness), it did not address qualified immunity—an analytically common approach in §1983 cases when the plaintiff fails at the first step.

C. Impact

  • Strengthened enforceability of “last resort” standards in prisons: The decision signals that broad, principle-based force limitations (like “last resort”) can satisfy due process notice requirements when applied to trained correctional staff, particularly where the record shows time to pursue alternatives.
  • Reduced viability of vagueness challenges to employee discipline rules in security settings: By emphasizing Hicks v. Illinois Dep't of Corr. and the “more latitude” afforded prison employers, the opinion may discourage attempts to constitutionalize disagreements over tactic selection unless the rule truly lacks discernible meaning.
  • Clarified interpretive hierarchy within regulatory schemes: The court’s reconciliation of §501.40(a)(1) with §501.30(a) underscores that specific force permissions operate within overarching restraints; regulated entities cannot isolate an authorization clause to negate a limiting principle.
  • Procedural discipline in §1983 employment litigation: The rejection of the “false reports” theory as unpleaded reinforces that plaintiffs must clearly identify each challenged rule or disciplinary basis in the complaint, not introduce new theories in opposition to summary judgment.
  • Operational takeaway for corrections agencies: Agencies can rely on “last resort” language, but should support enforcement with training, testimony, and documentary evidence of available alternatives—exactly the kind of record that carried the day here.

IV. Complex Concepts Simplified

Void for vagueness (Due Process)
A rule is unconstitutional if it is so unclear that a reasonable person cannot tell what it requires or forbids. The key question is fair notice and (often) whether the rule invites arbitrary enforcement.
As-applied vs. facial challenge
A facial challenge argues a rule is always vague; an as-applied challenge argues the rule was vague in the plaintiff’s particular situation. The officers brought only an as-applied challenge.
Summary judgment and “de novo” review
Summary judgment is decided on whether there is a genuine dispute of material fact requiring a trial. “De novo” appellate review means the court of appeals re-examines the legal issues without deferring to the district court’s legal conclusions.
“Not a super-personnel department”
Federal courts do not re-evaluate whether an employer made the best disciplinary choice; they decide whether the choice violated a legal right (here, due process).
Qualified immunity
A defense protecting officials from damages unless they violated clearly established constitutional law. The court did not reach it because it found no constitutional violation.
What counts as “force” under the regulations
“Force” includes physical contact used to coerce action and chemical agents. The court treated the planned coercive physical contact to remove the handcuffs as “force,” not merely what happened after the inmate’s later conduct.

V. Conclusion

The Seventh Circuit’s decision establishes that, in the prison employment context, a regulation requiring that “force shall be employed only as a last resort” is sufficiently definite to satisfy due process when applied to officers who had time and available alternatives before initiating a coercive physical plan. The opinion reinforces deference to prison administrators’ personnel regulation choices under Hicks v. Illinois Dep't of Corr., constrains attempts to repackage tactical disputes as constitutional vagueness claims, and underscores that separate due process challenges (such as to truthful-reporting rules) must be pleaded to be litigated.
