Reserved powers
Powers that are neither prohibited nor given by law to any organ of government / From Wikipedia, the free encyclopedia
For powers that may be exercised by a head of state without the approval of another branch of government, see Reserve power.
Reserved powers, residual powers, or residuary powers are the powers that are neither prohibited to be exercised by an organ of government, nor given by law to any other organ of government. Such powers, as well as a general power of competence, nevertheless may exist because it is impractical to detail in legislation every act allowed to be carried out by the state.[1]
