Administrative law
There is a need for administrative law because the interest of public could be at risk if various agencies were not following laws and regulations. Administrative law is important because without it, it could lead to arbitrary and unreasonable use of such discretion, which may lead to destruction of basic principles of administrative law. Although this type of discretion isn't laid out in the job-description of a bureaucrat/public servant, it is necessary because citizens use these bureaucratic institutions every day; such as the D.M.V. , public schooling, and numerous others. Street-level bureaucrats have to deal with the provision of service as well as translating vaguely worded mandates into specific cohesive and comprehensive language to organize protocol.
