====== Subsidiarity ======

Subsidiarity is a principle of political and social organization holding that decisions and responsibilities should be handled by the smallest, most local unit of authority capable of addressing them effectively, with larger or higher-level bodies intervening only when the matter genuinely exceeds the capacity of lower-level actors. The principle applies both vertically - across levels of government - and horizontally, between state and non-state institutions such as families, civic associations, religious bodies, and markets. Subsidiarity is distinct from simple decentralization in that it carries a normative presumption //against// the assumption of authority by higher levels, rather than treating the allocation of power as a neutral administrative choice.

====== Overview ======

The concept has roots in several intellectual traditions. In Catholic social teaching, subsidiarity was articulated systematically in Pope Leo XIII's encyclical //Rerum Novarum// (1891) and developed more fully in Pope Pius XI's //Quadragesimo Anno// (1931), which warned against the absorption of smaller social units by the state.((Pope Pius XI. //Quadragesimo Anno//. Vatican, 1931. §§ 79-80.)) The formulation that higher-order bodies should not usurp functions that lower-order bodies can perform adequately - and should positively support lower-order bodies when they cannot - remains central to Catholic social doctrine. Parallel arguments appear in Protestant social thought, in classical liberal political philosophy, and in federalist theory more broadly, though the term itself is most closely associated with the Catholic tradition.((Chaplin, Jonathan. "Subsidiarity and Social Pluralism." In //The Principle of Subsidiarity in Practice//. Centre for European Studies, 2011.))

In European political and legal contexts, subsidiarity gained significant institutional standing through the [[maastricht-treaty|Maastricht Treaty]] (1992), which incorporated it as a governing principle of the European Union. Under EU law, subsidiarity requires that the Union act only where the objectives of a proposed action cannot be sufficiently achieved by member states acting individually.((Treaty on European Union, Art. 5(3), as amended by the Treaty of Lisbon, 2007.)) This formulation applies subsidiarity between supranational and national levels, though critics have debated whether EU institutional practice has honored or eroded it in practice. That debate is addressed on the [[subsidiarity-eu-debate|Subsidiarity and the European Union - Debate]] page.

In the United States, subsidiarity is not named in the Constitution, but analogous reasoning underlies the Tenth Amendment's reservation of unenumerated powers to the states and the people, and appears in [[federalism|federalist]] arguments for limiting federal authority. The overlap between subsidiarity and American federalism is substantial but not complete: subsidiarity extends to non-governmental institutions and private associations in ways that federalism, as a doctrine of governmental structure, does not.((Aroney, Nicholas. "Subsidiarity, Federalism and the Best Constitution." //Law and Philosophy// 26, no. 4 (2007): 355-390.))

Subsidiarity intersects with debates over [[federalism|federalism]], the role of civil society, the appropriate scope of the administrative state, and the limits of government intervention in family and community life. It is invoked across the political spectrum - by conservatives defending local and religious institutions against state encroachment, by classical liberals defending individual and associational autonomy, and occasionally by progressives favoring community-based or participatory governance over centralized bureaucracy. The normative weight assigned to the principle and the level at which it is applied vary considerably across these uses.

The [[subsidiarity-history|history]] of subsidiarity as a concept spans medieval natural law theory, early modern political philosophy, and twentieth-century institutional development.

====== Consensus Status ======

There is broad agreement among political theorists that subsidiarity, as a formal principle, expresses a presumption in favor of lower-level authority and requires justification for higher-level intervention. Beyond this definitional core, there is no consensus on how to operationalize the principle, at what level the presumption should rest, or how competing claims between levels of authority should be resolved. Contested applications are addressed on the [[subsidiarity-debate|Subsidiarity - Debate]] page.

====== Viewpoints ======

**[[subsidiarity-catholic-social-teaching-viewpoint|Catholic Social Teaching]]** - The view, developed in papal encyclicals and elaborated in subsequent Catholic social doctrine, that subsidiarity is a moral principle grounded in human dignity and the natural structure of society, requiring that intermediate institutions - family, church, guild, and voluntary association - be protected from absorption by the state.

**[[subsidiarity-classical-liberal-viewpoint|Classical Liberal]]** - The view that subsidiarity, understood as a structural constraint on concentrated authority, supports individual liberty and limits state power, independently of its religious origins; associated with arguments for limited government, federalism, and the spontaneous order of civil society.

**[[subsidiarity-federalist-viewpoint|Federalist]]** - The view that subsidiarity provides normative grounding for constitutional federalism, requiring that legislative and regulatory authority be assigned to the most local level of government capable of handling a given matter, with higher levels bearing the burden of justification for intervention.

**[[subsidiarity-eu-integration-viewpoint|European Integration]]** - The view, institutionalized in EU treaty law, that subsidiarity governs the division of competence between supranational and member-state levels, ensuring Union action is limited to areas where collective action genuinely adds value over independent national action.

**[[subsidiarity-progressive-communitarian-viewpoint|Progressive Communitarian]]** - The view that subsidiarity supports participatory, community-based governance and can ground arguments for local democratic control over resources and services, though often applied to different institutional levels than in conservative or Catholic formulations.

**[[subsidiarity-social-conservative-viewpoint|Social Conservative]]** - The view that subsidiarity protects the family and religious institutions as the primary loci of moral formation and social provision, and that state welfare programs and regulatory mandates improperly displace these natural institutions.
