Article 2. The Mexican Nation is unique and indivisible.


The Nation has a multicultural composition originally sustained by its indigenous peoples, who are those descended from populations that inhabited the current territory of the country at the beginning of colonization and who preserve their own social, economic, cultural and political institutions, or part of them.


Awareness of their indigenous identity should be a fundamental criterion in determining to whom the provisions on indigenous peoples apply.


The communities that make up an indigenous people are those that form a social, economic and cultural unit, are settled in a territory and recognize their own authorities in accordance with their uses and customs.


The right of indigenous peoples to self-determination shall be exercised within a constitutional framework of autonomy that ensures national unity. The recognition of indigenous peoples and communities shall be made in the constitutions and laws of the federative entities, which shall take into account, in addition to the general principles established in the preceding paragraphs of this article, ethno-linguistic and physical settlement criteria.


A.          This Constitution recognizes and guarantees the right of indigenous peoples and communities to self-determination and, consequently, to autonomy to:


I.          Decide their internal forms of coexistence and social, economic, political and cultural organization.


II.          Apply their own normative systems in the regulation and resolution of their internal conflicts, subject to the general principles of this Constitution, respecting individual guarantees, human rights and, in a relevant manner, the dignity and integrity of women. The law will establish the cases and procedures for validation by the corresponding judges or courts.


III .         To elect, in accordance with their traditional rules, procedures and practices, the authorities or representatives for the exercise of their own forms of internal government, guaranteeing that indigenous women and men will enjoy and exercise their right to vote and be voted for under conditions of equality, as well as to access and hold the public and popularly elected positions for which they have been elected or appointed, within a framework that respects the federal pact, the sovereignty of the states and the autonomy of Mexico City. In no case may community practices limit the political-electoral rights of citizens in the election of their municipal authorities.

Reformed fraction DOF 22-05-2015, 29-01-2016


IV.          Preserve and enrich their languages, knowledge and all the elements that constitute their culture and identity.


V.          To conserve and improve the habitat and preserve the integrity of their lands under the terms established in this Constitution.


VI.          To have access, with respect to the forms and modalities of property and land tenure established in this Constitution and the laws of the matter, as well as to the rights acquired by third parties or by members of the community, to the preferential use and enjoyment of the natural resources of the places inhabited and occupied by the communities, except for those that correspond to strategic areas, in terms of this Constitution. For these purposes, the communities may associate under the terms of the law.


VII .         To elect, in municipalities with an indigenous population, representatives to the municipal councils, observing the principle of gender parity in accordance with the applicable norms.

Amended paragraph DOF 06-06-2019


The constitutions and laws of the federative entities shall recognize and regulate these rights in the municipalities, for the purpose of strengthening political participation and representation in accordance with their internal traditions and norms.


VIII.          Full access to the jurisdiction of the State. In order to guarantee this right, in all trials and proceedings to which they are a party, individually or collectively, their customs and cultural specificities must be taken into account, respecting the precepts of this Constitution. Indigenous people have the right at all times to be assisted by interpreters and defenders who have knowledge of their language and culture.


The constitutions and laws of the federative entities will establish the characteristics of self-determination and autonomy that best express the situations and aspirations of the indigenous peoples in each entity, as well as the norms for the recognition of indigenous communities as entities of public interest.

B .         In order to promote equal opportunities for indigenous people and eliminate any discriminatory practices, the Federation, the federal entities and the municipalities will establish the institutions and determine the policies necessary to guarantee the rights of indigenous people and the comprehensive development of their peoples and communities, which must be designed and operated jointly with them.

Amended paragraph DOF 29-01-2016

In order to reduce the shortages and backwardness that affect indigenous peoples and communities, these authorities have the obligation to:


I .         Promote the regional development of indigenous areas in order to strengthen local economies and improve the living conditions of their peoples, through coordinated actions among the three levels of government, with the participation of the communities. The municipal authorities will equitably determine the budgetary allocations that the communities will administer directly for specific purposes.


II.          To guarantee and increase levels of schooling, promoting bilingual and intercultural education, literacy, completion of basic education, productive training, and secondary and higher education. Establish a system of scholarships for indigenous students at all levels. Define and develop educational programs of regional content that recognize the cultural heritage of their peoples, in accordance with the laws of the matter and in consultation with the indigenous communities. Promote respect for and knowledge of the diverse cultures existing in the nation.

III.          To ensure effective access to health services by expanding the coverage of the national system, making due use of traditional medicine, and to support indigenous people's nutrition through food programmes, especially for the child population.


IV.          Improve the conditions of indigenous communities and their spaces for coexistence and recreation, through actions that facilitate access to public and private financing for the construction and improvement of housing, as well as expanding the coverage of basic social services.

V.          Promote the incorporation of indigenous women into development by supporting productive projects, protecting their health, providing incentives to promote their education and their participation in decision-making in community life.


VI.          Extend the communications network that allows the integration of communities, through the construction and expansion of communication and telecommunication routes. Establish conditions so that indigenous peoples and communities can acquire, operate and manage means of communication, under the terms determined by the relevant laws.


VII.          To support productive activities and the sustainable development of indigenous communities through actions that make it possible to achieve the sufficiency of their economic income, the application of stimuli for public and private investments that promote the creation of jobs, the incorporation of technologies to increase their own productive capacity, as well as to ensure equitable access to supply and marketing systems.


VIII.          Establish social policies to protect migrants from indigenous peoples, both within the national territory and abroad, through actions to guarantee the labour rights of agricultural day labourers; improve the health conditions of women; support special education and nutrition programmes for children and young people from migrant families; ensure respect for their human rights and promote the dissemination of their cultures.


IX .         To consult indigenous peoples in the preparation of the National Development Plan and the plans of the federal entities, municipalities and, where appropriate, the territorial divisions of Mexico City and, where appropriate, to incorporate the recommendations and proposals they make.

Reformed fraction DOF 29-01-2016

Without prejudice to the rights established herein in favour of indigenous peoples, their communities and peoples, any community comparable to them shall have the same rights as established by law.


C.          This Constitution recognizes the Afro-Mexican peoples and communities, whatever their self-designation, as part of the pluricultural composition of the Nation.

In relation to the amparo referred to in this subsection and Section V of this Article, the Collegiate Circuit Court shall decide on all the procedural violations that were asserted and those that, when appropriate, it finds in substitution of the complaint, and shall establish the precise terms in which the new decision must be rendered. If the procedural violations were not invoked in a first amparo, nor did the corresponding Collegiate Court assert them ex officio in the cases in which the substitution of the complaint is appropriate, they may not be the subject of a concept of violation, nor of an informal study in a subsequent amparo trial.

The party that has obtained a favorable judgment and the party that has a legal interest in the continuance of the challenged act may file an amparo in adhesive form to the one filed by any of the parties that intervened in the trial from which the challenged act emanates. The law shall determine the form and terms in which it must be filed.

In order for the proceeding to proceed, the ordinary remedies established in the law of the matter must be previously exhausted, by virtue of which those final judgments, awards and resolutions may be modified or revoked, except in the case in which the law permits the waiver of the remedies.

When claiming the final judgment, award, or resolution that ends the trial, violations of the laws of procedure must be asserted, provided that the complainant has challenged them during the processing of the trial through the remedy or means of defense that, as the case may be, the respective ordinary law indicates. This requirement shall not be enforceable in amparos against acts that affect the rights of minors or disabled persons, the civil status, or the order or stability of the family, nor in those of a criminal nature brought by the convicted person;

IV.          In administrative matters, amparo may also be granted against acts or omissions that come from authorities other than the judicial, administrative, or labor courts, and that cause an injury that cannot be repaired by any means of legal defense. It will be necessary to exhaust these means of defense whenever, in accordance with the same laws, the effects of such acts are suspended ex officio or through the filing of the suit, appeal, or means of legal defense that the aggrieved party asserts, with the same scope as those provided for in the regulatory law and without demanding greater requirements than those that the same law establishes for granting a definitive suspension, or a longer period than that established for the granting of a provisional suspension, regardless of whether or not the act in itself is susceptible of being suspended in accordance with the said law.


There is no obligation to exhaust such remedies or means of defense if the challenged act lacks grounds or when only direct violations of this Constitution are alleged;

The minimum occupational wages shall also be fixed taking into account the conditions of the various economic activities.

Minimum wages shall be set by a national commission composed of representatives of workers, employers and the government, which may be assisted by special commissions of a consultative nature that it deems indispensable for the best performance of its functions.

This obligation shall be fulfilled through the contributions that the companies make to a national housing fund in order to constitute deposits in favor of their workers and establish a financing system that allows them to be granted cheap and sufficient credit so that they may acquire ownership of such housing.

Their rulings and resolutions shall observe the principles of legality, impartiality, transparency, autonomy and independence.

Before going to the labor courts, workers and employers must attend the corresponding conciliatory instance. At the local level, the conciliatory function will be the responsibility of the Conciliation Centers, specialized and impartial, which will be established in the federal entities. These centers will have legal personality and their own assets. They will have full technical, operational, budgetary, decision-making and management autonomy. They will be governed by the principles of certainty, independence, legality, impartiality, reliability, efficiency, objectivity, professionalism, transparency and publicity. Their integration and functioning will be determined by local laws.

The law shall determine the procedure to be observed at the conciliation stage. In any case, the conciliation stage shall consist of a single mandatory hearing, with a date and time duly fixed in an expeditious manner. Subsequent conciliation hearings shall only be held with the agreement of the parties to the conflict. The law will establish the rules for labor agreements to acquire the status of res judicata, as well as for their enforcement.

At the federal level, the conciliatory function will be carried out by a decentralized body. The decentralized body shall also be responsible for the registration of all collective bargaining agreements and trade union organizations, as well as all related administrative processes.

The decentralized body referred to in the preceding paragraph shall have legal personality and its own assets, full technical, operational, budgetary, decision-making and management autonomy. It shall be governed by the principles of certainty, independence, legality, impartiality, reliability, efficiency, objectivity, professionalism, transparency and publicity. Its integration and operation will be determined in the law of the matter.

For the appointment of the head of the decentralized agency referred to in the preceding paragraph, the Federal Executive shall submit a list of three candidates to the consideration of the Senate, which, after the appearance of the proposed persons, shall make the corresponding appointment. The appointment shall be made by a two-thirds vote of the members of the Senate present, within a non-extendable period of thirty days. If the Chamber of Senators does not decide within said term, the person who, from among said list of three, is designated by the Federal Executive shall occupy the position.

In the event that the Chamber of Senators rejects the entire proposed list of three candidates, the Federal Executive shall submit a new one, under the terms of the preceding paragraph. If this second list of three candidates is rejected, the person designated by the Federal Executive shall occupy the position.

The appointment must be made to a person who has the capacity and experience in the areas of competence of the decentralized body; who has not held a position in any political party, nor been a candidate for public office in the three years prior to the appointment; and who enjoys a good reputation and has not been convicted of an intentional crime. He or she must also meet the requirements established by law. He or she shall serve for a term of six years and may be re-elected only once. In the event of absolute absence, the substitute will be appointed to complete the respective period. He may only be removed for serious cause under the terms of Title IV of this Constitution and may not hold any other employment, position or commission, with the exception of those in which they act on behalf of the body and those not remunerated in teaching, scientific, cultural or charitable activities.

XXI.          If the employer refuses to submit his differences to arbitration or to comply with the resolution, the employment contract shall be terminated and he shall be obliged to indemnify the worker with the amount of three months' salary, in addition to the liability resulting from the conflict. This provision shall not be applicable in the cases of the actions set forth in the following section. If the refusal is on the part of the workers, the employment contract will be terminated.

XXII.          The employer who dismisses a worker without just cause or for having joined an association or trade union, or for having taken part in a lawful strike, shall be obliged, at the choice of the worker, to fulfil the contract or to compensate him with the amount of three months' wages. The law shall determine the cases in which the employer may be exempted from the obligation to fulfil the contract by payment of compensation. The employer shall also have the obligation to compensate the worker with the amount of three months' salary when he withdraws from service due to lack of probity on the part of the employer or for receiving bad treatment from him, either in his person or in that of his spouse, parents, children or siblings. The employer may not exempt himself from this responsibility when the ill-treatment comes from dependents or relatives who act with the consent (sic DOF 21-11-1962) or tolerance of the employer.

Reformed fraction DOF 21-11-1962

XXII Bis. The procedures and requirements established by law to ensure freedom of collective bargaining and the legitimate interests of workers and employers shall guarantee, among others, the following principles:

a)         representativeness of trade union organizations, and

b)         Certainty in the signing, registration and deposit of collective bargaining agreements.

For the resolution of conflicts between trade unions, the request for the conclusion of a collective bargaining agreement and the election of leaders, the vote of the workers shall be personal, free and secret. The law shall guarantee compliance with these principles. Based on the foregoing, for the election of leaders, the trade union statutes may, in accordance with the provisions of the law, establish procedural modalities applicable to the respective processes.

XXIV.          For debts contracted by workers in favor of their employers, associates, family members or dependents, only the worker himself shall be liable, and in no case and for no reason may such debts be demanded from the members of his family, nor shall such debts be demandable for the amount in excess of the worker's salary in a month.

XXV.          The service for the placement of workers shall be free of charge for them, whether it is provided by municipal offices, labor exchanges or any other official or private institution.

XXVIII.          The laws shall determine the property constituting the patrimony of the family, which property shall be inalienable, shall not be subject to real encumbrances or attachments, and shall be transmissible by inheritance with simplification of the formalities of inheritance proceedings.

XXIX.          The Social Security Law is of public utility, and it shall include insurance for disability, old age, life, involuntary cessation of work, illness and accidents, childcare services and any other insurance aimed at the protection and welfare of workers, peasants, non-wage earners and other social sectors and their families.

Article 130 . The historical principle of the separation of the State and the churches guides the norms contained in this article. Churches and other religious groups shall be subject to the law.


It corresponds exclusively to the Congress of the Union to legislate on matters of public worship and churches and religious groups. The respective regulatory law, which shall be of public order, shall develop and specify the following provisions:


(a) Churches and religious groups shall have legal personality as religious associations once they have been registered. The law shall regulate such associations and determine the conditions and requirements for their constitutive registration.


(b) The authorities shall not intervene in the internal life of religious associations;


(c) Mexicans may exercise the ministry of any religion. Mexicans as well as foreigners must, for this purpose, meet the requirements established by law;


(d) Under the terms of the regulatory law, ministers of religion may not hold public office. As citizens, they shall have the right to vote, but not to be voted for. Those who have ceased to be ministers of religion in advance and in the manner established by law may vote.


(e) Ministers may not associate for political purposes or proselytize for or against any candidate, party or political association. Nor may they, in public meetings, in acts of worship or religious propaganda, or in publications of a religious nature, oppose the laws of the country or its institutions, or in any way offend the national symbols.


It is strictly forbidden to form any kind of political grouping whose title has any word or indication that relates it to any religious denomination. Meetings of a political nature may not be held in churches.


The simple promise to tell the truth and to fulfill the obligations contracted, subjects the promisor, in the event that he fails to do so, to the penalties established by law.


Ministers of worship, their ascendants, descendants, siblings and spouses, as well as the religious associations to which they belong, shall be incapable of inheriting by will from persons whom the ministers themselves have directed or assisted spiritually and who are not related to them within the fourth degree.


The acts of civil status of persons are the exclusive competence of the administrative authorities under the terms established by law, and shall have the force and validity attributed to them therein.


The federal authorities, the authorities of the federal entities, of the municipalities and of the territorial divisions of Mexico City, will have in this matter the powers and responsibilities determined by law.
