In jail or prison, a DO is a disciplinary offense: the formal label staff use when they believe someone in custody broke a facility rule. Once an offense is written up, it starts an internal process that can take away privileges, send the person to segregation, and in many cases push the release date further out. Every facility runs on its own rulebook, but the structure is consistent across jails and prisons, and the federal Bureau of Prisons publishes the most detailed version of it.
How Disciplinary Offenses Are Classified
Facilities sort prohibited conduct by severity, and the severity level sets the ceiling on punishment. The federal Bureau of Prisons uses four tiers.1eCFR. 28 CFR 541.3 – Prohibited Acts and Available Sanctions
- Greatest severity covers killing, assault causing serious injury, escape, rioting, taking hostages, and possession of weapons or firearms.
- High severity covers fighting, threatening bodily harm, extortion, and escape from a work detail with voluntary return within four hours.
- Moderate severity covers possessing unauthorized money, misusing medication, indecent exposure, and possessing items not issued through regular channels.
- Low Moderate severity covers faking illness, abusive language, unauthorized physical contact, and visitor-rule violations.
Attempting a prohibited act, or helping someone else commit one, is treated the same as doing it. State prisons and county jails use comparable tiered systems with their own labels and categories. The principle is the same wherever you are: how serious the alleged offense is determines how harsh the available penalty is.
What Happens After You Get a DO
It begins with an incident report. A staff member who witnesses or suspects a rule violation writes up what happened and which rule was broken. In the federal system, the person charged ordinarily receives this report within 24 hours of staff learning about the incident.2eCFR. 28 CFR 541.5 – Discipline Process
An investigator then looks into the allegation. You are told the specific charges and informed of the right to remain silent. Silence won’t be treated as an automatic admission, but an unfavorable inference can be drawn from it.2eCFR. 28 CFR 541.5 – Discipline Process You can give a statement, ask for witnesses to be interviewed, and request that other evidence be reviewed.
Lower-level cases often stop at a unit-level committee review. In the federal system, the Unit Discipline Committee can resolve many Moderate and Low Moderate reports on its own or refer the matter upward. Serious cases go to a Discipline Hearing Officer, who must be impartial — not a witness, victim, or investigator in the incident. You get written notice of the charges at least 24 hours before that hearing, which you can waive. The hearing officer then finds that you committed the act, did not commit it, or that more investigation is needed.3eCFR. 28 CFR 541.8 – Discipline Hearing Officer (DHO) Hearing
Not every report reaches a hearing. Moderate and Low Moderate offenses can be resolved informally at any stage, and when that happens the incident report is removed from your record. Informal resolution is not available for Greatest or High severity violations.2eCFR. 28 CFR 541.5 – Discipline Process
What You’re Entitled to at the Hearing
A disciplinary hearing is not a criminal trial, and the protections are narrower. The Supreme Court set the baseline in Wolff v. McDonnell: advance written notice of the charges at least 24 hours before the hearing, a written statement from the decision-maker explaining the evidence relied on and the reasons for the finding, and the opportunity to call witnesses and present evidence.4Justia. Wolff v. McDonnell, 418 U.S. 539 (1974) Officials can limit witnesses when allowing them would threaten institutional safety, but they cannot refuse without reason.
The proof needed to find you guilty is minimal. Under Superintendent v. Hill, the standard is “some evidence”: any evidence in the record that could support the conclusion is enough, and a reviewing court will not reweigh the evidence or judge credibility.5Justia. Superintendent v. Hill, 472 U.S. 445 (1985) This is where expectations and reality often collide. The bar is not “beyond a reasonable doubt.” It is not even “preponderance of the evidence.” It is genuinely low.
You can request a staff representative at a Discipline Hearing Officer hearing, as long as that person was not involved in the incident. If the person you want is unavailable, the warden appoints someone, and the warden must appoint a representative if you cannot adequately represent yourself — for example, if you cannot read or struggle to understand the charges. The representative helps you prepare, lines up witnesses, gathers written statements, and assists during the proceeding.3eCFR. 28 CFR 541.8 – Discipline Hearing Officer (DHO) Hearing You do not have a right to an attorney.
Penalties You Can Face
A guilty finding opens the door to sanctions tied to the severity level.1eCFR. 28 CFR 541.3 – Prohibited Acts and Available Sanctions
- Loss of privileges, including visiting, telephone, commissary, and recreation. This is available at every level and is the most common sanction for lower-level offenses.
- Disciplinary segregation, with federal first-offense ceilings of up to 60 days for Greatest, 30 days for High, 15 days for Moderate, and 7 days for Low Moderate. Repeat offenses within a set window raise those ceilings.
- Monetary fines, imposed alone or alongside other sanctions.
- Housing changes, including transfer to a different unit, a higher-security facility, or another institution.
State and county facilities set their own ranges. Some state systems allow substantially longer segregation for a single offense than the federal rules do.
How a DO Can Add Time to Your Sentence
The sanctions above are temporary compared to what a disciplinary offense can do to your release date.
Federal inmates serving sentences longer than one year can earn up to 54 days of good conduct time per year, and that credit depends on the Bureau of Prisons finding “exemplary compliance with institutional disciplinary regulations” during the year.6Office of the Law Revision Counsel. 18 USC 3624 – Release of a Prisoner If the Bureau finds compliance was not satisfactory, it can award reduced credit or none. Credit that was never earned cannot be granted later. For Greatest severity acts, up to 100% of earned good conduct time can be forfeited.1eCFR. 28 CFR 541.3 – Prohibited Acts and Available Sanctions A single serious write-up can wipe out months of credit.
First Step Act time credits are separate from good conduct time but also vulnerable. The amounts that can be lost per offense track severity: up to 41 days for Greatest, up to 27 for High, up to 14 for Moderate, and up to 7 for a second Low Moderate offense of the same type within six months.1eCFR. 28 CFR 541.3 – Prohibited Acts and Available Sanctions
In state systems where parole exists, disciplinary records weigh heavily. Boards review institutional conduct, and even a single misconduct report can undermine an otherwise clean file. Sanctions can also knock you out of the programs and education tracks that parole boards reward, which makes the next hearing harder. Good behavior alone rarely guarantees parole, but documented misconduct is almost always enough to delay or deny it.
Appealing a DO
You can appeal a guilty finding, and using that appeal matters beyond the dispute itself. Under the Prison Litigation Reform Act, a federal lawsuit about prison conditions cannot proceed unless administrative remedies have been exhausted first.7Office of the Law Revision Counsel. 42 USC 1997e – Suits by Prisoners Skipping the internal process means a court will dismiss the case, and once the appeal deadline passes the door may be shut for good.
In the federal system, there are two levels after the warden’s response. A written appeal goes to the Regional Director within 20 calendar days of receiving the warden’s answer, and if that outcome is unsatisfactory, a second appeal goes to the General Counsel within 30 calendar days of the Regional Director’s response. The General Counsel’s step is the final administrative one. Each appeal must use the correct Bureau form, state specific reasons, and stay within the issues raised earlier.8eCFR. 28 CFR Part 542 – Administrative Remedy State and county timelines are often shorter. Missing a deadline by a single day can forfeit the right to challenge the decision, so start tracking the calendar from the moment the guilty finding is delivered.
Why a DO Follows You
The consequences of a disciplinary offense do not end when the sanction is served. The record stays in your file and feeds future decisions. Security classification reviews can push you to a higher-security facility with fewer freedoms and fewer programs. Access to work assignments, education, and reentry preparation can be restricted based on disciplinary history.
After release, a documented misconduct record can surface during supervised release or probation hearings. For people convicted of federal crimes, conduct documented during incarceration can factor into whether a court modifies the terms of supervised release. A single DO can compound over time, shaping daily conditions inside and the actual date you walk out.
