Given the large number of individuals under supervision through the Interstate Compact for Adult Offender Supervision (ICAOS, or the Compact), legal actions against judicial officials, correctional staff, and other administrators of the Compact are inevitable. This chapter discusses the various pathways through which those actors might face legal liability for their work. It also considers the different types of immunity and related defenses available to those actors when they are sued. This chapter is not intended as a comprehensive resource on these subjects, which turn out to be especially complicated and subject to numerous exceptions as a matter of state law. Rather, it is meant as a survey of liability and immunity issues that have actually arisen in the context of the Compact.
