In fact private companies, especially large ones, also have bureaucracies. Negative perceptions of “red tape” aside, public services such as schooling, health care, policing or public transport are considered a crucial state function making public bureaucratic action the locus of government power. In 1934, the Austrian philosopher Hans Kelsen continued the positivist tradition in his book the Pure Theory of Law News. Kelsen believed that although law is separate from morality, it is endowed with “normativity”, meaning we ought to obey it. While laws are positive “is” statements (e.g. the fine for reversing on a highway is €500); law tells us what we “should” do.

Public international law has a special status as law because there is no international police force, and courts (e.g. the International Court of Justice as the primary UN judicial organ) lack the capacity to penalise disobedience.

The fundamental constitutional principle, inspired by John Locke, holds that the individual can do anything except that which is forbidden by law, and the state may do nothing except that which is authorised by law. Administrative law is the chief method for people to hold state bodies to account. People can sue an agency, local council, public service, or government ministry for judicial review of actions or decisions, to ensure that they comply with the law, and that the government entity observed required procedure. The first specialist administrative court was the Conseil d’État set up in 1799, as Napoleon assumed power in France.
