Administrative state
The administrative state is a term used to describe the power that some government agencies have to write, judge, and enforce their own laws. Since it pertains to the structure and function of government, it is a frequent topic in political science, constitutional law, and public administration.
The phenomenon was relatively unknown in representative democracies before the end of the 1800s. Its sudden rise has generated considerable scholarship, writing, and study to understand its causes and effects, and to square it with previous notions of law and governance.
