Fighting inside a correctional facility triggers an immediate and structured disciplinary response, and the consequences stack depending on how serious the incident was.
Both participants get pulled out of general population and placed in the SHU, the hole, right away. From there the case goes to the Disciplinary Hearing Officer, known as the DHO. That title sounds formal but the reality is more concentrated than a courtroom. The DHO functions as lawyer, judge, and jury all in one. The hearing happens quickly, the inmate can call one character witness to speak on their behalf, and the decision comes down on the spot with the penalty enforced immediately.
Who you bring as your witness matters enormously. Another inmate carries almost no credibility in that room. A corrections officer who has observed your person over time, particularly one who supervised them at a work detail or program, carries real weight because staff testimony is trusted in a way that inmate testimony simply is not.
The penalties the DHO can impose depend on the severity of the fight. A minor scuffle with no injuries might result in a short stay in the hole and temporary loss of privileges like phone time, visitation, and commissary. A fight involving serious injuries, weapons, or significant property damage can result in loss of good time credits, which pushes the release date back, and a custody level increase, which means a transfer to a higher security facility.
The aggressor typically faces harsher consequences than someone who was defending themselves, though the DHO makes that determination based on the incident report and any witness accounts. The best outcome in any fight situation is to have stayed out of it entirely. The second best is to have a staff member who can speak to your character when you are sitting in front of that DHO.
