What piece of legislation ensures the protection of inmates’ religious rights?

The Religious Land Use and Institutionalized Persons Act (RLUIPA) is the piece of legislation that specifically ensures the protection of inmates' religious rights. This law was enacted to prevent government entities from imposing substantial burdens on the religious exercise of individuals, including those who are incarcerated.

RLUIPA establishes that prisons and other institutions must accommodate an inmate's religious beliefs as long as doing so does not pose a threat to safety or order within the facility. It recognizes the importance of religious expression and provides a legal framework for inmates to practice their faith, making it a crucial protection for religious freedom in correctional settings.

The other legislative options mentioned do not specifically address the religious rights of inmates. The Prison Rape Elimination Act focuses on preventing sexual assault and ensuring safety in correctional facilities, the Prisoner's Rights Act encompasses broader issues concerning the rights of prisoners in terms of treatment and conditions but doesn’t specifically target religious rights, and the Inmate Safety Act centers around overall safety and security without specific considerations for religious practices. The RLUIPA stands out as the legislation aimed directly at protecting the religious exercise of those in institutional settings.
