Inmate Rights in Missouri

Missouri's prison rights landscape in 2024 and 2025 is defined by active litigation on multiple fronts. In May 2025, the MacArthur Justice Center filed a class action lawsuit against the Missouri Department of Corrections challenging dangerously high temperatures at Algoa Correctional Center as cruel and unusual punishment. People in solitary confinement at Algoa had no access to electrical outlets for fans and could shower only three days per week, with heat indexes reaching 120 degrees outside the facility during summer 2024. Separately, the MacArthur Justice Center and ACLU of Missouri have sued over systematic denial of Hepatitis C treatment to people in MODOC custody, and over the Missouri Parole Board's assembly line process that has pushed people back into prison by tricking or pressuring them into waiving their right to a parole revocation hearing.

The Missouri Department of Corrections, known as MODOC, refers to incarcerated people as offenders in its official communications. MODOC operates under Director Trevor Foley and has approximately 11,000 employees. Missouri also has a documented problem with death reporting: a November 2025 Marshall Project and Missouri Independent investigation found that prison deaths were never made public, contradicting MODOC's own statement that deaths are reported as they occur. MODOC began collating death reports into a weekly report in 2024 but that change was not retroactive.

This guide covers rights inside Missouri state prisons and county jails across ten domains, grounded in MODOC policy, Missouri statute, and the current legal landscape.

Here is the short version, before we take each right apart.

Medical and mental health care are constitutionally required. MODOC has been sued over systematic denial of Hepatitis C treatment. Mail in Missouri state prisons is processed through a Securus JPay scanning system; greeting cards are not allowed by physical mail and must be sent through Securus; all mail is inspected. Phone calls run through the contracted provider and are subject to FCC rate caps. Visitation requires prior approval through a visitor application process. Grievances follow Missouri statute Section 217.370 and must be exhausted before a federal lawsuit. Disciplinary hearings carry due process protections. Extreme heat in facilities without air conditioning has been the subject of active May 2025 litigation. PREA protections apply. Religious practice is protected under the First Amendment and RLUIPA. ADA accommodations are required. Missouri's felony disenfranchisement law under Section 115.133 bars voting while incarcerated and while on parole or probation, with voting rights automatically restored upon final discharge. Parole revocation processes have been the subject of a federal class action alleging due process violations.

Medical and mental health care

Every person in a Missouri state prison has a constitutional right to adequate medical and mental health care under the Eighth Amendment. MODOC contracts for health care services across its facilities. Medical requests go through the facility health services unit.

Missouri has active litigation on two health care fronts. The MacArthur Justice Center and the ACLU of Missouri jointly filed a federal class action challenging MODOC's systematic denial of potentially life saving medication to people with chronic Hepatitis C, a treatable but often denied condition in state prisons nationwide. Additionally, the May 2025 heat lawsuit at Algoa Correctional Center noted that about 400 people are in a heat sensitive class due to age or medical conditions, meaning their health care needs make them particularly vulnerable to the extreme temperatures documented at the facility. If your loved one is not receiving needed medical or mental health care, submit every request in writing with a date, keep copies, and file a formal grievance. Contact the ACLU of Missouri for systemic health care concerns.

Mail and correspondence

Missouri state prison mail is processed through a Securus JPay scanning system. Physical greeting cards are not allowed through the mail to MODOC facilities. Families and friends can send electronic mail, digital greeting cards, pictures, and 30 second videos through a Securus JPay account. For security purposes, all incoming and outgoing mail is subject to inspection. The following items will cause a mailing to be rejected: unsanitary mail including bodily fluid or powdery substances; mail with labels, stickers, or stamps other than required postage; photos containing nudity; correspondence written in a foreign language or that is indecipherable may be censored or delayed based on staff availability for interpretation.

Legal mail, meaning correspondence with courts and licensed attorneys, must be opened only in the incarcerated person's presence to check for physical contraband and cannot be read. This constitutional protection applies across all MODOC facilities. If correspondence is determined not to be in compliance with policy, both the incarcerated person and the sender are notified. An incarcerated person who disagrees with a censorship decision may file an appeal through the offender grievance process. A sender who disagrees may submit a written request for an independent review within 30 days to the warden. InmateAid can help families confirm current mailing addresses and procedures.

Phone and video contact

Phone calls from Missouri state prisons are placed through a contracted provider. Calls are monitored and recorded except for calls to attorneys. Phone rates are subject to the FCC's prison telephone rate caps, expanded in 2024 to cover all facilities regardless of size. Each offender arrives at MODOC with postage paid correspondence materials and can set up phone and electronic communication accounts.

Families can send electronic mail, digital greeting cards, pictures, and 30 second videos through a Securus JPay account. This electronic messaging system is available at MODOC facilities as a supplement to physical mail and phone calls. InmateAid can help families set up prepaid accounts, confirm current phone rates at the specific facility, and maintain the regular contact that supports better outcomes after release.

Visitation

Visitation in Missouri state prisons requires prior approval through the MODOC visitor application process. Each offender must notify approved visitors of the facility specific visiting schedule. MODOC's visitor application asks whether the applicant has ever been employed with the Department of Corrections. All visitors are subject to search requirements upon arrival.

MODOC policy on protective orders and no contact directives governs who may visit. Visitation schedules and rules vary by facility and by the offender's custody level. If a visit is denied or a visitor is removed from an approved list, the incarcerated person may seek review through the MODOC grievance process. County jails in Missouri operate under local authority with their own separate visiting rules. Contact InmateAid for current visiting information for a specific MODOC facility.

The grievance process

Missouri statute Section 217.370 requires MODOC to establish discipline and grievance procedures and requires the chief administrative officer to abide by them. Missouri statute Section 510.125 additionally requires the department to maintain a grievance resolution system. Grievances must be exhausted through the available MODOC process before filing a federal civil rights lawsuit under the Prison Litigation Reform Act.

File every grievance in writing, keep a copy, and document every response and every failure to respond within required timeframes. For mail censorship decisions, MODOC provides an additional independent review process through the warden within 30 days of notification. For systemic concerns, the ACLU of Missouri and the MacArthur Justice Center have both filed lawsuits based on documented patterns in MODOC facilities and can be contacted after the internal grievance process has been completed.

Disciplinary hearings

When a person in Missouri state custody is accused of a disciplinary infraction, they are entitled to the minimum due process protections from Wolff v. McDonnell: advance written notice of the charge, a hearing, and a written statement of the evidence and reasons for any sanction. Missouri statute Section 217.370 requires MODOC to establish disciplinary procedures and the chief administrative officer to abide by them.

A disciplinary conviction can affect classification, housing assignment, program eligibility, visiting access, and consideration for early release. Document what happened at any disciplinary hearing, who was present, and what evidence was considered. If the hearing result appears to violate procedural requirements, file a grievance and appeal through the MODOC process.

Extreme heat: the May 2025 lawsuit

On May 12, 2025, the MacArthur Justice Center filed a class action lawsuit against MODOC officials on behalf of people incarcerated at Algoa Correctional Center, a nearly 100 year old facility in Jefferson City without central air conditioning. The lawsuit is Hamilton v. Foley. The complaint alleges that the prison's conditions during summer months constitute cruel and unusual punishment in violation of the Eighth Amendment. Heat indexes reached 120 degrees outside Algoa during summer 2024, described as the hottest recorded year in U.S. history.

For people in solitary confinement at Algoa, the conditions are particularly severe. Those in Housing Unit 3 have no access to electrical outlets to power fans, can shower only three days per week, and are not allowed out of their cells and therefore cannot access the one air conditioned room in the recreation area. The MacArthur Justice Center described the floor of Housing Unit 3 as literally soaking wet from sweat and humidity during summer months. MODOC's informal heat mitigation practices at Algoa consisted of limited access to ice in a cooler, access to warm showers, the option to purchase one small personal fan, and unreliable limited access to cooler rooms. The lawsuit seeks a heat mitigation plan keeping housing unit temperatures between 65 and 85 degrees. Approximately 400 people are in the heat sensitive class and 86 are in solitary confinement.

Parole revocation rights

The Missouri Parole Board has been the subject of active federal litigation. The MacArthur Justice Center filed a class action lawsuit in the Western District of Missouri alleging that MODOC and the Parole Board have run an assembly line parole revocation process that pushes people back into prison without real legal protections. The lawsuit alleges that in many instances, alleged parole violators are tricked or pressured into waiving their right to a hearing and returned to prison without any process at all.

The constitutional due process protections for parole revocation hearings require advance notice of alleged violations, a hearing, and the opportunity to present evidence and witnesses. Waiving a revocation hearing should be a fully informed, voluntary decision, not the product of pressure or misrepresentation. If your loved one is on parole in Missouri and facing revocation, document every communication with the parole officer and every step of the revocation process. The MacArthur Justice Center and ACLU of Missouri are monitoring this area and can be contacted.

PREA and protection from sexual abuse

The Prison Rape Elimination Act applies in all MODOC facilities and in Missouri county jails. Every person in custody has the right to be free from sexual abuse and sexual harassment by staff and by other incarcerated people. MODOC must maintain PREA policies, train staff, provide a reporting mechanism, and protect people who report from retaliation.

Missouri statute Section 566.145 establishes that sexual contact with inmates by staff is a crime, and that consent is not a defense. This statutory protection exists alongside the PREA requirements. One notable MODOC case involved Honesty Bishop, an HIV positive transgender woman held in solitary confinement for more than 2,000 days, which led to policy changes at MODOC through MacArthur Justice Center litigation. Reports of sexual abuse or harassment can be made to facility staff or the PREA coordinator. Retaliation against someone who reports is a PREA violation.

Religious practice

People incarcerated in Missouri state prisons have the right to religious practice under the First Amendment and the federal Religious Land Use and Institutionalized Persons Act. MODOC must accommodate sincere religious beliefs and practices unless it can demonstrate a compelling security interest that cannot be addressed through less restrictive means. Religious programming and chaplaincy services are available in MODOC facilities.

Requests for specific religious accommodations, including dietary adjustments and access to religious items, go through a formal request process at the facility. A denial must rest on a genuine documented security concern. Denials can be challenged through the MODOC grievance process and, if unresolved, in federal court under RLUIPA. Document the specific accommodation requested, the reason given for any denial, and every step taken.

ADA and disability accommodations

People with disabilities in Missouri state prisons are protected by the Americans with Disabilities Act. MODOC must provide reasonable accommodations for people with mobility, vision, hearing, cognitive, and other disabilities, and must ensure they can participate in programs and services on an equal basis. Requests for disability accommodations should be submitted in writing to the facility.

A denial or failure to respond can be challenged through the MODOC grievance process and, if unresolved, in federal court. The May 2025 heat lawsuit specifically identified people with heat sensitive medical conditions as a class requiring accommodation, because the extreme temperatures at Algoa are particularly dangerous for people with certain health conditions. Document every accommodation requested and every response received.

Voting rights and reentry

Missouri's felony disenfranchisement law under Section 115.133 of the Missouri Revised Statutes bars voting while incarcerated and while on probation or parole after a felony conviction. Voting rights are automatically restored when a person is finally discharged from probation or parole. People under a Suspended Imposition of Sentence, known as SIS, which is not considered a conviction, may vote while on that form of supervision.

As of May 2025, approximately 57,000 Missourians under MODOC supervision on probation or parole after a felony conviction were barred from voting. Legislation to restore voting rights during probation or parole was proposed in the 2025 session but did not pass. Upon final discharge, people must re register to vote, as Missouri removes felons from voter registration upon conviction. Contact your local election authority or the Missouri Secretary of State at 800 669 8683 to re register after final discharge.

The bottom line for Missouri

Missouri's prison rights landscape in 2024 and 2025 is shaped by active litigation on multiple fronts: extreme heat at Algoa in the May 2025 class action, Hepatitis C treatment denial in a separate MacArthur and ACLU lawsuit, and parole revocation due process failures in a federal class action in the Western District of Missouri. The MacArthur Justice Center closed its St. Louis office in early 2026, but its active cases continue.

The rights in this guide are real: adequate medical care, legal mail protections, mail inspection with independent warden review for censorship appeals, phone and electronic messaging through Securus JPay, visitation through the MODOC approval process, a grievance process under Missouri statute Sections 217.370 and 510.125, due process in disciplinary hearings, Eighth Amendment protection against extreme heat conditions documented in active litigation, PREA protection with a statutory prohibition on staff sexual contact, religious accommodation, disability access, and voting rights automatically restored upon final discharge from probation or parole. Document everything, file every grievance, contact the ACLU of Missouri for systemic concerns, and stay in contact through InmateAid.
