The Spanish Public Administration is the governmental body in charge of managing the country's public interests. In article 103.1 of the 1978 Constitution, it is stated that the Public Administration serves objectively the public interest and acts in line with the principles of efficiency, hierarchy, decentralization, deconcentration, and coordination, while being fully subject to the law. The General State Administration, the Administrations of the Autonomous Communities, the Entities that Integrate the Local Administration, as well as public organisms and entities of public law, are defined as Public Administration by Law 40/2015, of October 2, on the Juridical Regime of the Public Sector. The Spanish Public Administration is made up of a variety of administrations that can be divided into three categories: territorial administrations (which include the General State Administration), instrumental or institutional administrations (which rely on personnel to function), and corporative administrations (group of people of the same guild that sometimes they do activities of a public nature). In order to serve the public good, public administrations wield a plethora of sweeping authorities over private legal entities. Administrations are subject to a set of constraints and safeguards of the rule of law as a counterweight to such sweeping powers (submission to the law, judicial review, property guarantees, etc.).
