Principle of Subsidiarity

problems are best solved in the subsystem where they arise. This is similar to the idea of management by exception. Subsystems are encouraged to resolve their conflicts themselves without referring them to higher authority. Whatever solution is adopted, the subsystem will have to carry it out. Since their consent is essential, the optimum condition is for them to resolve their conflicts independently. If a solution is worked out by the subsystem, appeal to authority is not necessary.
