In this full-length analysis of the Civil Aviation Authority, Baldwin examines the place of such agencies in British government, the interaction between the adjudicative and policymaking functions, the structure of regulatory discretions and administrative justice, the role of trial-type procedures in licensing, and how specialist agencies can be efficient and accountable to government control. Baldwin concludes that the regulatory agency is likely to play an increasingly large role in British government and considers how the relationship between the two can be arranged for maximal efficiency.
