Inmates do not forfeit the right to practice their religious faith while they are incarcerated. But of course that right is not unlimited. Officers can impose certain restrictions when an inmate’s religious practices would conflict with the institution’s legitimate interests in safety, security, and good order. There is a lot of case law about those restrictions, both as a constitutional matter under the First Amendment, and under a federal statute, the Religious Land Use and Institutionalized Persons Act of 2000 (RLUIPA), 42 U.S.C. § 2000cc-1(a)(1)–(2)—which is even more protective of inmates’ rights than the Constitution.
