One noticeable feature of modern legal systems is the extent to which power is conferred upon government officials and agencies to be exercized at their discretion, according to policy considerations, rather than according to precise legal standards. This book is a legal and jurisprudential analysis of discretionary power in modern legal systems, with particular emphasis on the consequences of discretion in the relationship between the individual and the state. Readership: legal scholars working in administrative law and jurisprudence.
