["Law & Society Review, Volume 55, Issue 2, Page 296-319, June 2021. ", "\nAbstract\nPrison laws and policies often do not explicitly state the rights and privileges for the individuals residing there. This space is a unique example of where the law‐on‐the‐books meet the law‐in‐action—a place where “law‐in‐between” operates in the hands of street‐level workers. Using data collected from interviews with restricted housing unit residents and staff in four men's prisons, this paper examines how the law‐in‐between operates in a highly structured and punitive environment. Findings reveal agreement among residents and staff regarding general definitions and perceptions of rights, with some similarities regarding what rights are broadly. However, divergence exists in discussion of how rights are accessed in practice.\n"]
