Quick answer
First-grade prison classification is the closed regime, the most restrictive situation in serving a sentence, designed for inmates classified as showing extreme dangerousness or a manifest inability to adapt to the ordinary and open regimes. Its application is exceptional and requires reinforced reasoning grounded in the inmate's specific conduct, not in the nature of the offence. Continued classification must be reviewed periodically, at least every three months, and classification or regression to first grade can be appealed before the Prison Supervision Judge and then before the Provincial Court.

Classification in first grade is the most restrictive situation in serving a sentence. It means the closed regime, with strong limitations on movement and communal life. As criminal defence lawyers, we explain how to challenge it.
What First Grade Is
First grade corresponds to the closed regime, designed for inmates classified as showing extreme dangerousness or a manifest inability to adapt to the ordinary and open regimes. It is the most severe grade of the prison system.
When It Applies
The application of first grade is exceptional. The nature of the offence is not enough: it must be grounded in the inmate's specific conduct within the facility. The rules require reinforced reasoning.
⚠️ An exceptional measure
First grade cannot become a disguised sanction. Case law requires objective, current facts justifying extreme dangerousness, not mere suspicion.
Periodic Reviews
Continued first-grade classification must be reviewed periodically, at least every three months. At each review the administration must assess whether the causes persist or whether progression to second grade is appropriate.
How to Appeal First Grade
Classification or regression to first grade can be appealed before the Prison Supervision Judge and then before the Provincial Court. The defence works to rebut the reasoning, prove the inmate's progress and seek grade progression.
