Article 27 of the Mexican Constitution
Name	Article 27 of the Mexican Constitution
Country	Mexico
Enacted	1917
Subject	Land reform; property rights; natural resources

Article 27 of the Mexican Constitution is a foundational provision in the Constitution of Mexico that defines Mexican ownership of land and natural resources and frames agrarian rights, property regimes, and state control over subsoil assets. It has been central to disputes involving Porfirio Díaz, Venustiano Carranza, Emiliano Zapata, Lázaro Cárdenas, Plutarco Elías Calles, and later administrations such as Miguel de la Madrid and Enrique Peña Nieto. The article shaped policies affecting Ejido, latifundio, agrarian reform, oil expropriation, and interactions with foreign investors including companies like Royal Dutch Shell, Standard Oil, and ExxonMobil.

Text and Scope

The text establishes that all land and water within the national territory originally belong to the nation, reserving for the Estados Unidos Mexicanos the right to transfer private ownership and regulate uses; it also grants the nation exclusive rights over subsoil minerals, including hydrocarbons and strategic deposits. This scope associates the article with provisions in instruments such as the Constitution of 1857, the Plan of Ayala, and the 1917 Constitution as promulgated by the Constituent Congress (1916–1917). The provision's language interfaces with property regimes like private property, communal land, and ejido system, and implicates institutions such as the Secretariat of Agrarian, Land, and Urban Development and the Federal Electricity Commission.

Historical Background

The article emerged from revolutionary debates involving leaders like Francisco I. Madero, Pancho Villa, Emiliano Zapata, and Venustiano Carranza; it responded to the concentration of land under figures associated with Porfirio Díaz and the Porfiriato period, and to conflicts such as the Mexican Revolution. Influences included earlier measures like the Ley de Desamortización and events such as the Mexican–American War which reshaped territorial concepts. The 1917 formulation was implemented during presidencies of Venustiano Carranza and later expanded under Lázaro Cárdenas in the 1930s, notably during the Mexican oil expropriation of 1938 that confronted companies including Shell Mex, Standard Oil of New Jersey, and drew attention from the League of Nations and international actors like Franklin D. Roosevelt.

Land Reform and Agrarian Policy

Article 27 became the legal basis for large-scale land redistribution, transforming estates held by families like the López Mateos allies and the Ocampo magnates into ejidos and agrarian communities. Implementations under presidents such as Lázaro Cárdenas, Adolfo López Mateos, and Gustavo Díaz Ordaz involved coordination with agencies like the National Agrarian Registry and legal instruments related to agrarian law. The policy affected regions including Chiapas, Morelos, Baja California, and Oaxaca, and intersected with movements like the Zapatista Army of National Liberation which later invoked land rights discourse. Land reform cases reached tribunals influenced by jurisprudence from the Supreme Court of Justice of the Nation and interactions with international financiers such as the World Bank.

Property Rights and Natural Resources

Beyond agrarian titles, the article reserves underground resources to the nation, framing nationalization efforts including the 1938 oil expropriation that created Petróleos Mexicanos and relations with companies like Gulf Oil and actors such as Álvaro Obregón. The state’s prerogatives affected mining operations in states like Zacatecas and Sonora and regulated concessions to entities comparable to Anaconda Copper, Peabody Energy, and transnational corporations. The constitutional regime has been engaged in disputes over hydrocarbon exploration, offshore rights near Gulf of Mexico basins, and environmental controversies with organizations like the International Union for Conservation of Nature and regional actors such as Comisión Nacional del Agua.

Legal Interpretation and Key Jurisprudence

Judicial interpretation by the Supreme Court of Justice of the Nation and rulings from collegiate circuit courts have clarified collective ownership, ejido transfers, and state monopoly exceptions. Landmark decisions involved judges and justices who shaped doctrine similar to precedents in cases referencing entities such as Pemex and disputes with corporations like Chevron and BP. Jurisprudence has engaged concepts reflected in international arbitration involving tribunals like the International Centre for Settlement of Investment Disputes and bilateral investment treaties with countries such as the United States and United Kingdom. Key legal debates have referenced scholars and jurists like Ignacio Burgoa Orihuela and institutions such as the National Autonomous University of Mexico.

Amendments and Political Controversies

Amendments in the late 20th and early 21st centuries, notably during the administrations of Carlos Salinas de Gortari, Vicente Fox, and Enrique Peña Nieto, altered aspects of ejido commercialization, private participation, and hydrocarbon regulation, sparking debate among parties like the Institutional Revolutionary Party, National Action Party, and Party of the Democratic Revolution. Controversies involved protests by groups such as the Zapatista Army of National Liberation and negotiations with investors including Repsol and TotalEnergies. High-profile reforms prompted discourse in media outlets like El Universal and La Jornada and mobilized civil society organizations, labor unions like the Confederation of Mexican Workers, and international observers including the United Nations.
