Prison Disciplinary Process in Maryland

How Maryland prisons handle write-ups under COMAR 12.03.01, from the hearing officer and offense categories to lost diminution credits, parole, and appeals.

If you or someone you love is doing time in a Maryland state prison, the disciplinary system is one of the few parts of the place that can reach out and add real days to a sentence. People who have never been inside think the punishment is the cell time. It is not. In Maryland the cell time is almost the small part. The part that hurts is what a guilty finding does to your diminution credits and to the way the Parole Commission reads your file. This article walks through how the whole thing actually works, in plain language, from the voice of someone who has watched it play out on a tier more than a few times.

The agency that runs the prisons is the Maryland Department of Public Safety and Correctional Services, usually called DPSCS, and the piece inside it that holds sentenced adults is the Division of Correction. The disciplinary rules live in the Code of Maryland Regulations, COMAR 12.03.01, titled the Inmate Disciplinary Process. That chapter took effect in 2018 and it replaced the older inmate discipline regulation that a lot of guys still call by its old number. If you are reading an old handbook or an old jailhouse memo, check the date, because the categories and the procedure were reorganized.

A few words you will hear on the tier. A write-up is the disciplinary report. Officers and old heads also call it a shot or a ticket. None of those are the official name. On paper it is a Notice of Inmate Rule Violation, and that form, plus the Notice of Inmate Disciplinary Hearing that rides with it, is the document that starts everything. When somebody says they caught a ticket, that is what they mean.

How the categories work

Maryland does not use one flat list of offenses. It groups every rule violation into a category based on how serious it is, and the category drives almost everything that follows. There are six of them. Category IA is the most severe. Then Category IB, then II, III, IV, and finally Category V, which is the least severe. Each violation also has a number, so an officer will write you up for a specific numbered rule inside a category.

Category IA is the heavy stuff. It covers participating in a disruptive act, assault or battery on staff, on another inmate, or on someone who is neither, making threats of physical harm, possessing or making a weapon, escape from medium or maximum security, possessing escape tools, destroying security or monitoring equipment, sexual acts and sexual conduct, masturbation directed at staff, possessing a cell phone or other telecommunication device, homicide, and taking a hostage. The cell phone rule sits in IA, which surprises people, because a phone is treated nearly as seriously as a weapon in Maryland.

Category IB is also serious. It covers escape from pre-release status or from the community, possessing drugs or a controlled dangerous substance or an intoxicant, using them, possessing them in distribution quantity, refusing or diluting a urine test, unauthorized financial accounts, distribution quantities of tobacco, possessing fifty dollars or more in currency above what you are allowed, and knowingly filing a false PREA report or misusing the PREA hotline.

Category II is a short list that mostly involves refusing mandatory education or remediation programs, refusing DNA collection or fingerprinting, and disobeying a specifically cited facility Category II rule. Categories III, IV, and V step down from there. Category III picks up tattoos and tattoo equipment, alcohol, hoarding medication, gambling, extortion and bribery, theft and destruction of state or personal property, possessing or passing contraband, indecent exposure, and the catch-all of disobeying an order. Category IV covers being somewhere you are not allowed, false information or forged documents, smaller currency amounts, unauthorized phone calls and three-way calls, disrespect and vulgar language, and limited personal-use tobacco. Category V is the lightest, mostly failing to display your ID badge, horseplay, and failing to keep yourself or your area clean.

Why the category matters so much: if you are charged with a Category IA, IB, or II violation, the case must go to a formal hearing in front of a hearing officer. There is no shortcut. If you are charged with only a Category III, IV, or V violation, staff may offer you an informal resolution instead of a hearing, but they are not required to. More on that below.

How a write-up actually starts

It begins with an investigation. When staff have cause to believe you broke a rule, they are supposed to look into the facts, identify witnesses, and secure evidence before they write anything. After that, the reporting officer fills out the reported-facts section of the Notice of Inmate Rule Violation and forwards it up to the shift supervisor, generally within one day of finishing the investigation.

The shift supervisor reviews it, decides which rule or rules to charge, and can send a defective report back to be fixed. The supervisor also decides whether to recommend that you sit on administrative segregation while the case is pending, which happens when your conduct or your disciplinary history is seen as a threat to safety or security. If segregation is recommended, the shift commander reviews and approves it. Understand that this pre-hearing segregation is not a punishment and is not a finding of guilt. It is a holding status, and Maryland is explicit that time spent there, missed work, lost privileges, or a transfer cannot by themselves get a charge thrown out later.

Getting served and the requests you must make

Before you ever see a hearing officer, staff are supposed to serve you with a copy of the Notice of Inmate Rule Violation and the Notice of Inmate Disciplinary Hearing, normally within twenty-four hours of the supervisor or commander finishing the review. This is the most important moment in the whole process and almost nobody treats it that way.

Here is the trap. When you sign for that paperwork, the hearing notice has sections where you request a representative by name, request your witnesses by name, and request specific evidence with a description. If you do not name your representative, name your witnesses, and describe your evidence right then, Maryland treats it as a waiver. Bring it up for the first time later at the hearing and the hearing officer can deny it. If you refuse to sign, get disruptive, or do not hand the facility copy back, that too can be treated as a waiver of timely service and of your right to ask for representation, witnesses, or evidence at all. So read the paper, and fill in the names and the evidence while the pen is in your hand. Do not wait. Do not assume you can sort it out at the hearing.

If you cannot read or do not understand the form, say so when you are served, because that triggers help. If you need an interpreter or you are illiterate, the hearing officer is supposed to make a finding about that and provide a representative or an interpreter, and another inmate is not allowed to serve as your interpreter.

Informal resolution versus a formal hearing

For a Category III, IV, or V charge, staff may offer you an informal resolution. That comes in two flavors. One is an informal disposition, where you accept a sanction without a hearing. The other is an incident report, where you take no sanction at all but the paperwork stays in your file. Either way, accepting means you waive the hearing and you waive the right to appeal that disposition. You are never required to accept. You can reject the offer and demand a formal hearing in front of the hearing officer. Whether that is the smart move depends on the evidence against you and on what sanction they are offering, so think it through rather than reacting.

The hearing is the ballgame

If your case goes formal, it lands in front of a hearing officer. In Maryland the hearing officer is a single impartial fact-finder, not a committee or a panel of three. The preliminary hearing is supposed to be scheduled within seven business days of service, and it cannot be held inside the first twenty-four hours unless you waive that notice or you are about to be released.

The proceeding has two parts. First the preliminary review, where the hearing officer goes over the charge, your representation, witness, and evidence requests, any plea or informal resolution, and any claim that the paperwork or the timing was defective. Then the evidentiary phase, where the facility puts on its case and you put on yours.

Pay attention to the standard of proof, because this is a real Maryland feature. The hearing officer weighs the evidence and makes findings based on a preponderance of the evidence, meaning more likely than not. That is a higher bar than the bare some-evidence floor that the federal system and a lot of states use. It does not make these hearings easy to beat, but it does mean the facility has to do more than wave a report at the wall, and a good, organized presentation can actually move the needle.

This is where the old advice holds. Put everything into the hearing. Your best witness in most cases is not another inmate, it is your work-assignment supervisor or a staff member who knows your work and your conduct, because the hearing officer sets the sanction and a credible good word from staff tends to pull a penalty toward the lighter end of the range. Line that up before the hearing, while you are filling out the request form, not after. Do not save your defense for an appeal. In Maryland, as everywhere, the appeal is narrow and rarely changes the result. The hearing is the ballgame.

The proceeding is recorded by both a written summary and an audio recording, and if it cannot be recorded the hearing officer is supposed to postpone rather than proceed. If you refuse to appear or get yourself removed for being disruptive, the hearing officer goes ahead without you and rules on the charge anyway, so walking out or acting up only means you lose your chance to be heard.

The sanctions, and the one that really matters

A guilty finding can bring several things. The hearing officer can impose disciplinary segregation, and Maryland sets the segregation amounts through adjustment-history sentencing matrices, which key the allowable segregation to the offense category and to your prior disciplinary record. Segregation sanctions cannot be stacked to run consecutively, and if you already sat on administrative segregation on this case you get credit for that time. The hearing officer can also suspend privileges, order restitution for damaged or stolen property and for costs you caused, assign you to a sanitation detail that pays nothing and earns no credit, and impose other alternative sanctions.

But the sanction that actually changes your release date is the revocation of earned diminution credits, and to understand that you have to understand how Maryland lets you out.

Maryland diminution credits, the real release lever

Maryland is a credit state with a parole system layered on top, and the disciplinary process is wired straight into both. Diminution credits are day-for-day reductions of your term, and they come in four buckets under the Correctional Services Article, Title 3, Subtitle 7.

Good conduct credits are the big one. You are awarded an initial block of them up front, calculated across your whole term, subject to you keeping your conduct clean. The standard rate is ten days for every month of the sentence. If your term of confinement includes a sentence for a crime of violence as defined in the Criminal Law Article, or for certain controlled-substance distribution crimes, the rate drops to five days a month. Then there are work-task credits at up to five days a month, education credits at up to five days a month, and special-projects credits at up to ten days a month for qualifying assignments, which often ride on top of a work or education detail. Add them up and a well-behaved person on a non-violent sentence can knock a serious amount off the calendar.

Here is the disciplinary hook, and it is a Maryland distinctive worth knowing cold. When you are found guilty of a rule violation, the Division can revoke a portion or all of your good conduct credits and your special-projects credits, according to the nature and frequency of the violation. That is the statute at Correctional Services Article 3-709. But that same statute says the revocation does not touch the work-task credits or the education credits you have already earned. In other words, the credits you earned by going to work and by going to school are protected from a disciplinary write-up, while the front-loaded good conduct block and the special-projects credits are exposed. That protection for work and education credit is unusual, and it is a real reason to stay on a job and in a program.

A guilty finding does not have to be permanent on the credit side. The Division can restore revoked diminution credits, and the standing practice generally looks at whether you have stayed clean, typically with no guilty finding and no segregation in the months leading up to a restoration and with release coming into view. Restoration is discretionary, not automatic, so the way you earn it back is the same way you avoid losing it: keep your nose clean.

Parole and your institutional adjustment

Maryland kept its Parole Commission, which is not true in every state, so the disciplinary record matters a second way. Most people become eligible for a parole hearing after serving one-fourth of the aggregate sentence. For a violent crime committed on or after October 1, 1994, eligibility moves to the greater of one-half of the sentence for the violent crimes or one-fourth of the total. When the Commission decides whether to grant parole, one of the central things it weighs is your institutional adjustment, which is the polite term for your disciplinary history inside. Life and homicide cases go before a panel of two commissioners, and parole of a lifer also runs through the Governor.

So put the two pieces together. A single guilty finding can revoke good conduct and special-projects credits, which pushes back your mandatory supervision date, and it lands in the institutional adjustment summary that the Parole Commission reads when it decides whether to let you out early. One write-up can cost you on both levers at once. That is why discipline in Maryland is not really about the segregation cell. It is about the calendar.

Watch your back when you get close to the door

This part is not in any regulation, and it is the part that costs people their release more often than the rules do. When you get short, when you become a short-timer, a shortie, you become a target. There are long-timers who cannot stand watching somebody walk out, and the move is ugly and underreported: contraband gets planted near a shortie's bunk so a write-up delays the release. The contraband itself often travels by suitcasing, which is hiding an item in a body cavity to beat a search. The quieter version of the same thing is a long-timer who catches a shortie palming food, gambling, or doing something small, and drops a note to staff, meaning he tips them off, just to watch the short-timer eat a ticket.

The defense is simple and it is the oldest advice on the tier. The last six months before the door, keep your circle tight, keep your bunk and your area clean, do not gamble, do not hold anything for anybody, and do not put yourself anywhere a planted item or a dropped note can reach you. In Maryland, where one Category III contraband finding can cost you good conduct and special-projects credits and show up in front of the Parole Commission, those last months are exactly when a clean record is worth the most.

Appeals, and why they are not your plan A

You do have an appeal, but understand its limits before you pin hopes on it. You appeal a hearing officer's decision in writing to the managing official of your facility, and you have to do it within fifteen calendar days of receiving the decision. Miss that window and you have both waived the appeal and failed to exhaust your administrative remedies, which matters a great deal if you ever want a court to look at the case later. The managing official reviews the record, generally within thirty days, and an important guardrail applies: the managing official cannot increase the sanction the hearing officer imposed. The managing official can also kick the case to the Secretary of the Department for a fresh proceeding if the decision looks clearly wrong.

Beyond that, complaints about prison conditions and many other grievances run through the Administrative Remedy Procedure, the ARP, with an appeal to the Commissioner, and then to the Inmate Grievance Office. But for the disciplinary decision itself, the road is the managing official and then the Secretary. The appeal is real, but it is narrow, it looks mainly at the sufficiency of the evidence, the interpretation of the rules, and the sanction, and it rarely overturns a clean hearing. Build your case at the hearing, not on appeal.

Staying in touch with someone in segregation

If your person is on administrative or disciplinary segregation, phone access and visits often get cut back or cut off, and that is exactly when families lose contact and panic. The most reliable way to reach someone in segregation is physical mail, and photos sent through the approved process. A letter gets to a man in the hole when a phone call cannot, it gives him something to hold, and it keeps him steady through the part of the bid where steadiness keeps him out of more trouble. Keep writing, keep the letters coming, and send photos. That mail is often the only line that stays open.

Frequently asked questions

What are the offense categories in Maryland prisons?

Maryland groups every rule violation into six categories by severity, from Category IA, the most serious, down through IB, II, III, IV, and Category V, the least serious. The category sets whether you get a formal hearing and how heavy the sanctions can be.

Who decides a Maryland disciplinary case?

A single hearing officer, an impartial fact-finder, decides the case and sets the sanction. Maryland does not use a three-member committee for this.

What standard of proof is used?

The hearing officer decides by a preponderance of the evidence, meaning more likely than not. That is a higher bar than the some-evidence standard many systems use.

Can a write-up cost me good time in Maryland?

Yes. A guilty finding can revoke good conduct and special-projects diminution credits under the rules, which pushes back your release date. Work-task and education credits you already earned are protected from revocation.

Does a disciplinary record affect parole?

Yes. Maryland still has a Parole Commission, and your institutional adjustment, which is your disciplinary history, is one of the main things it weighs when deciding whether to grant parole.

How do I appeal a guilty finding?

File a written appeal with the facility managing official within fifteen calendar days of getting the decision. Missing that deadline waives the appeal and means you have not exhausted your remedies.

Can my sanction get worse if I appeal?

No. The managing official reviewing your appeal cannot increase the sanction the hearing officer imposed.

What is the smartest thing to do when I get written up?

Name your representative, your witnesses, and your evidence on the hearing notice the moment you are served, line up a staff or work-supervisor witness, and put your whole defense into the hearing. The appeal is narrow and rarely changes the result. === VERIFICATION LOG (STRIP BEFORE PUBLISH) === Proposed slug: inmateaid.com/disciplinary-process/maryland/ (lock, never change) PRIMARY SOURCES (live-verified this session): 1.
