subsidiarity

noun

1. (uncountable, usually)The principle that initiative (whether in government, business or religion) ought to reside at the lowest feasible level (i.e. at the local or regional level, instead of the national or supranational level, unless the latter presents clear advantages)

   “According to the principle of subsidiarity, government should be as habitative as possible. Government functions must therefore be exercised at the most habitative level, as close as possible to those affected by the exercise of such functions.”
