This ethnography of everyday policing practices in Lucknow, a major Indian metropolis, demonstrates how police authority and its assumed afflictions are refracted through a multi-dimensional field of social relationships in which power positions and moral boundaries are continually contested and shifting. This field generates among police what legal anthropologist Beatrice Jauregui calls provisional authority, a fractured and contingent form of capability and subjectivity that is not always immediately visible or comprehensible. Provisional authority may provide a social good, but with questionable and transmutable efficacy or legitimacy. Drawing on scholarship from anthropology, legal history, sociology, and political theory, Jauregui considers prevalent problems like routinized corruption, bureaucratized cronyism, evidence fabrication and extralegal violence among police as expressions of strategic adaptation and often a sincere if failing attempt to perform what officers themselves consider real police work in the face of interference, incapacity, disaffection and fragmented knowledge. This analysis of the fraught nature of police authority in India pushes contemporary theories of state power, legality and legitimacy, and postcolonialism and decolonization in different and provocative directions, opening new vistas for understanding policing as a global historical practice hybridizing local, statist, and transnational modes of producing and performing authority and order. Provisional Authority offers an innovative and challenging read of classical and contemporary theories of the postcolonial state, and an incisive perspective on public order in relation to police authority as co-configured by practice and subjectivity."
