A sentenced inmate has lost good-time credit due to a violation of jail rules, but was not afforded a disciplinary hearing. Which constitutional amendment is impacted?

The situation described involves a sentenced inmate losing good-time credit without being afforded a disciplinary hearing, which raises significant concerns related to due process. The 14th Amendment of the United States Constitution guarantees that individuals cannot be deprived of life, liberty, or property without due process of law. In the context of inmates, this means that they have certain rights concerning disciplinary actions that could affect their good-time credits or other privileges.

When an inmate is found to have violated jail rules, any resulting punishment, such as losing good-time credit, must follow a fair process, which typically includes a hearing where the inmate can present their case, challenge the evidence against them, and have an opportunity to be heard. In this instance, failing to provide that disciplinary hearing constitutes a violation of the inmate's right to due process as established under the 14th Amendment. This amendment is instrumental in protecting the rights of individuals, particularly regarding administrative actions that affect their liberty interests, such as incarceration and sentence reductions.

Therefore, the correct answer pertains to the 14th Amendment, as it addresses the fundamental principles of fairness in legal proceedings that should apply even within the correctional system.
