= a principle in the social doctrine of the Catholic Church, which gives preference to civil society and lower level groups, that has also been adopted by political bodies such as the European Union
From the Wikipedia:
"Subsidiarity is an organizing principle that matters ought to be handled by the smallest, lowest or least centralized competent authority. The Oxford English Dictionary defines subsidiarity as the idea that a central authority should have a subsidiary function, performing only those tasks which cannot be performed effectively at a more immediate or local level. The concept is applicable in the fields of government, political science, cybernetics and management. Subsidiarity is, ideally or in principle, one of the features of federalism.
The word subsidiarity is derived from the Latin word subsidiarius and has its origins in Catholic social teaching. The concept or principle is found in several constitutions around the world (see for example the Tenth Amendment to the United States Constitution).
It is presently best known as a fundamental principle of European Union law. According to this principle, the EU may only act (i.e. make laws) where member states agree that action of individual countries is insufficient. The principle was established in the 1992 Treaty of Maastricht, and is contained within the proposed new Treaty establishing a constitution for Europe. However, at the local level it was already a key element of the European Charter of Local Self-Government, an instrument of the Council of Europe promulgated in 1985 (see Article 4, Paragraph 3 of the Charter)" (http://en.wikipedia.org/wiki/Subsidiarity)

"What is Subsidiarity?
“a. Value of civil society
417. The political community is established to be of service to civil society, from which it originates. The Church has contributed to the distinction between the political community and civil society above all by her vision of man, understood as an autonomous, relational being who is open to the Transcendent. This vision is challenged by political ideologies of an individualistic nature and those of a totalitarian character, which tend to absorb civil society into the sphere of the State. The Church’s commitment on behalf of social pluralism aims at bringing about a more fitting attainment of the common good and democracy itself, according to the principles of solidarity, subsidiarity and justice.
Civil society is the sum of relationships and resources, cultural and associative, that are relatively independent from the political sphere and the economic sector. “The purpose of civil society is universal, since it concerns the common good, to which each and every citizen has a right in due proportion”. This is marked by a planning capacity that aims at fostering a freer and more just social life, in which the various groups of citizens can form associations, working to develop and express their preferences, in order to meet their fundamental needs and defend their legitimate interests.
b. Priority of civil society
418. The political community and civil society, although mutually connected and interdependent, are not equal in the hierarchy of ends. The political community is essentially at the service of civil society and, in the final analysis, the persons and groups of which civil society is composed. Civil society, therefore, cannot be considered an extension or a changing component of the political community; rather, it has priority because it is in civil society itself that the political community finds its justification.
The State must provide an adequate legal framework for social subjects to engage freely in their different activities and it must be ready to intervene, when necessary and with respect for the principle of subsidiarity, so that the interplay between free associations and democratic life may be directed to the common good. Civil society is in fact multifaceted and irregular; it does not lack its ambiguities and contradictions. It is also the arena where different interests clash with one another, with the risk that the stronger will prevail over the weaker.
c. Application of the principle of subsidiarity
419. The political community is responsible for regulating its relations with civil society according to the principle of subsidiarity. It is essential that the growth of democratic life begin within the fabric of society. The activities of civil society — above all volunteer organizations and cooperative endeavours in the private-social sector, all of which are succinctly known as the “third sector”, to distinquish from the State and the market — represent the most appropriate ways to develop the social dimension of the person, who finds in these activities the necessary space to express himself fully. The progressive expansion of social initiatives beyond the State- controlled sphere creates new areas for the active presence and direct action of citizens, integrating the functions of the State. This important phenomenon has often come about largely through informal means and has given rise to new and positive ways of exercising personal rights, which have brought about a qualitative enrichment of democratic life.
420. Cooperation, even in its less structured forms, shows itself to be one of the most effective responses to a mentality of conflict and unlimited competition that seems so prevalent today. The relationships that are established in a climate of cooperation and solidarity overcome ideological divisions, prompting people to seek out what unites them rather than what divides them.
Many experiences of volunteer work are examples of great value that call people to look upon civil society as a place where it is possible to rebuild a public ethic based on solidarity, concrete cooperation and fraternal dialogue. All are called to look with confidence to the potentialities that thus present themselves and to lend their own personal efforts for the good of the community in general and, in particular, for the good of the weakest and the neediest. In this way, the principle of the “subjectivity of society” is also affirmed.” ()
MESSAGE OF THE HOLY FATHER JOHN PAUL II TO THE PARTICIPANTS IN THE SIXTH PLENARY SESSION OF THE PONTIFICAL ACADEMY OF SOCIAL SCIENCES, par 4:
smaller social units — whether nations themselves, communities, ethnic or religious groups, families or individuals — must not be namelessly absorbed into a greater conglomeration, thus losing their identity and having their prerogatives usurped. Rather, the proper autonomy of each social class and organization, each in its own sphere, must be defended and upheld. This is nothing other than the principle of subsidiarity, which requires that a community of a higher order should not interfere in the internal life of a community of a lower order, depriving the latter of its rightful functions; (http://www.vatican.va/holy_father/john_paul_ii/speeches/2000/jan-mar/documents/hf_jp-ii_spe_20000223_acd-sciences-plenary_en.html)
INTERVENTION BY THE HOLY SEE AT THE WORLD SUMMIT ON SUSTAINABLE DEVELOPMENT
In keeping with the principle of subsidiarity, the poor must be heard on issues and be at the center of local, national and international programs for sustainable development. Persons living in poverty must be considered as participating subjects. Individuals and peoples cannot become tools but must be the protagonists of their future,9 able to be the "agents of their own development" (http://www.vatican.va/roman_curia/secretariat_state/documents/rc_seg-st_doc_20020902_martino-johannesburg_en.html)
