In the age of American mass incarceration, a complex legal regime governs prison conditions and presents a host of controversial questions at the intersection of constitutional liberty, statutory interpretation, administrative regulation, and public policy. This is a completely overhauled, re-titled, and much-expanded version of the leading casebook about incarceration. It addresses both pretrial and post-conviction incarceration, presenting Supreme Court and leading lower court case law, statutes, litigation materials, professional standards, academic commentary, and prisoner writing. Topics include conditions of confinement, civil liberties, particular prisoner populations and relevant legal issues (race and national origin discrimination, the particular issues/law governing treatment of incarcerated women, LGBTQ people, and people with disabilities). Litigated remedies (injunctive litigation, damages, the Prison Litigation Reform Act, and criminal prosecution of prison staff), are also covered in detail, as is non-litigation oversight. The casebook is supplemented by an open-access website that offers additional resources and sources for further reading.
