Completing, perhaps, Mexico's lurch towards radicalism, a new constitution was ratified on this day. It had been passed on January 31 of the same year.



The 1917 Constitution remains in effect, with amendments, to the current day. It was based on one earlier in effect under Benito Juarez, but was amended and more radical than Carranza had proposed or wanted.









Reflecting the views of the side that was winning the Mexican Revolution, which was still ongoing, it was one of the most radical constitutions of its era, and it remains a radical one. It reflected certain social movements of the day, such as the drift towards prohibition, and various social progressive movements, but it also reflected the extreme radicalism at work in the world at the time. It was very hostile to religion, reflecting the radicalism of the prevailing parties in the Mexican Revolution.

It was also excessively bulky.



Attempting to address far too many topics, and having provisions that would have been much more appropriately addressed as conventional law, the constitution is nearly endless. Documents of this type are rarely successful and, whatever a person's view is about the success of the Mexican constitution, it is far too long of document.

In its original form:





1917 Constitution of Mexico TITLE ONE Chapter I Individual Guarantees



Article 1. Every person in the United Mexican States shall enjoy the guarantees granted by this Constitution, which cannot be restricted or suspended except in such cases and under such conditions as are herein provided





Article 2. Slavery is forbidden in the United Mexican States. Slaves who enter national territory from abroad shall, by this act alone, recover their freedom and enjoy the protection afforded by the laws.





Article 3.(1) The education imparted by the Federal State shall be designed to develop harmoniously all the faculties of the human being and shall foster in him at the same time a love of country and a consciousness of international solidarity, in independence and justice.





I.Freedom of religious beliefs being guaranteed by Article 24, the standard which shall guide such education shall be maintained entirely apart from any religious doctrine and, based on the results of scientific progress, shall strive against ignorance and its effects, servitudes, fanaticism, and prejudices. Moreover:





a.It shall be democratic, considering democracy not only as a legal structure and a political regimen, but as a system of life founded on a constant economic, social, and cultural betterment of the people;





b.It shall be national insofar as -- without hostility or exclusiveness -it shall achieve the understanding of our problems, the utilization of our resources, the defense of our political independence, the assurance of our economic independence, and the continuity and growth of our culture; and





c.It shall contribute to better human relationships, not only with the elements which it contributes toward strengthening and at the same time inculcating, together with respect for the dignity of the person and the integrity of the family, the conviction of the general interest of society, but also by the care which it devotes to the ideals of brotherhood and equality of rights of all men, avoiding privileges of race, creed, class, sex, or persons.





II.Private persons may engage in education of all kinds and grades. But as regards elementary, secondary, and normal education (and that of any kind or grade designed for laborers and farm workers) they must previously obtain, in every case, the express authorization of the public power. Such authorization may be refused or revoked by decisions against which there can be no judicial proceedings or recourse.





III.Private institutions devoted to education of the kinds and grades specified in the preceding section must be without exception in conformity with the provisions of sections I and II of the first paragraph of this article and must also be in harmony with official plans and programs.





IV.Religious corporations, ministers of religion, stock companies which exclusively or predominantly engage in educational activities, and associations or companies devoted to propagation of any religious creed shall not in any way participate in institutions giving elementary, secondary and normal education and education for laborers or field workers.





V.The State may in its discretion withdraw at any time the recognition of official validity of studies conducted in private institutions.





VI.Elementary education shall be compulsory.





VII.All education given by the State shall be free.





VIII.The Congress of the Union, with a view to unifying and coordinating education throughout the Republic, shall issue the necessary laws for dividing the social function of education among the Federation, the States and the Municipalities, for fixing the appropriate financial allocations for this public service and for establishing the penalties applicable to officials who do not comply with or enforce the pertinent provisions, as well as the penalties applicable to all those who infringe such provisions.





Article 4. No person can be prevented from engaging in the profession, industrial or commercial pursuit, or occupation of his choice, provided it is lawful. The exercise of this liberty shall only be forbidden by judicial order when the rights of third parties are infringed, or by administrative order, issued in the manner provided by law, when the rights of society are violated. No one may be deprived of the fruits of his labor except by judicial decision.The law in each state shall determine the professions which may be practiced only with a degree, and set forth the requirements for obtaining it and the authorities empowered to issue it.





Article 5.(2) No one can be compelled to render personal services without due remuneration and without his full consent, excepting labor imposed as a penalty by the judiciary, which shall be governed by the provisions of clauses I and II of Article 123. Only the following public services shall be obligatory, subject to the conditions set forth in the respective laws: military service and jury service as well as the discharge of the office of municipal councilman and offices of direct or indirect popular election. Duties in relation to elections and the census shall be compulsory and unpaid. Professional services of a social character shall be compulsory and paid according to the provisions of law and with the exceptions fixed thereby.The State cannot permit the execution of any contract, covenant, or agreement having for its object the restriction, loss or irrevocable sacrifice of the liberty of man, whether for work, education, or religious vows. The law, therefore, does not permit the establishment of monastic orders, whatever be their denomination or purpose. Likewise no person can legally agree to his own proscription or exile, or to the temporary or permanent renunciation of the exercise of a given profession or industrial or commercial pursuit.





A labor contract shall be binding only to render the services agreed on for the time set by law and may never exceed one year to the detriment of the worker, and in no case may it embrace the waiver, loss, or restriction of any civil or political right. Non-compliance with such contract by the worker shall only render him civilly liable for damages, but in no case shall it imply coercion against his person.





Article 6. The expression of ideas shall not be subject to any judicial or administrative investigation, unless it offends good morals, infringes the rights of others, incites to crime, or disturbs the public order.





Article 7. Freedom of writing and publishing writings on any subject is inviolable. No law or authority may establish censorship, require bonds from authors or printers, or restrict the freedom of printing, which shall be limited only by the respect due to private life, morals, and public peace. Under no circumstances may a printing press be sequestrated as the instrument of the offense.

The organic laws shall contain whatever provisions may be necessary to prevent the imprisonment of the vendors, newsboys, workmen, and other employees of the establishment publishing the work denounced, under pretext of a denunciation of offenses of the press, unless their guilt is previously established.





Article 8. Public officials and employees shall respect the exercise of the right of petition, provided it is made in writing and in a peaceful and respectful manner; but this right may only be exercised in political matters by citizens of the Republic. Every petition shall be replied to in writing by the official to whom it is addressed, and said official is bound to inform the petitioner of the decision taken within a brief period.





Article 9. The right to assemble or associate peaceably for any lawful purpose cannot be restricted; but only citizens of the Republic may do so to take part in the political affairs of the country. No armed deliberative meeting is authorized. No meeting or assembly shall be deemed unlawful which has for its object the petitioning of any authority or the presentation of a protest against any act; nor may it be dissolved, unless insults be proffered against said authority or violence is resorted to, or threats are used to intimidate or compel such authority to render a favorable decision.





Article 10. The inhabitants of the United Mexican States are entitled to have arms of any kind in their possession for their protection and legitimate defense, except such as are expressly forbidden by law, or which the nation may reserve for the exclusive use of the army, navy, or national guard; but they may not carry arms within inhabited places without complying with police regulations.





Article 11. Everyone has the right to enter and leave the Republic, to travel through its territory and to change his residence without necessity of a letter of security, passport, safe-conduct or any other similar requirement. The exercise of this right shall be subordinated to the powers of the judiciary, in cases of civil or criminal liability, and to those of the administrative authorities insofar as concerns the limitations imposed by the laws regarding emigration, immigration and public health of the country, or in regard to undesirable aliens resident in the country.





Article 12. No titles of nobility, or hereditary or prerogatives or honors shall be granted in the United Mexican States, nor shall any effect be given to those granted by other countries.





Article 13. No one may be tried by private laws or special tribunals. No person or corporate body shall have privileges or enjoy emoluments other than those given in compensation for public services and which are set by law. Military jurisdiction shall be recognized for the trial of crimes against and violation of military discipline, but the military tribunals shall in no case have jurisdiction over persons who do not belong to the army. Whenever a civilian is implicated in a military crime or violation, the respective civil authority shall deal with the case.





Article 14. No law shall be given retroactive effect to the detriment of any person whatsoever. No person shall be deprived of life, liberty, property, possessions, or rights without a trial by a duly created court in which the essential formalities of procedure are observed and in accordance with laws issued prior to the act. In criminal cases no penalty shall be imposed by mere analogy or by a prior evidence. The penalty must be decreed in a law in every respect applicable to the crime in question. In civil suits the final judgment shall be according to the letter or the juridical interpretation of the law; in the absence of the latter it shall be based on the general principles of law.





Article 15. No treaty shall be authorized for the extradition of political offenders or of offenders of the common order who have been slaves in the country where the offense was committed. Nor shall any agreement or treaty be entered into which restricts or modifies the guarantees and rights which this Constitution grants to the individual and to the citizen.





Article 16. No one shall be molested in his person, family, domicile, papers, or possessions except by virtue of a written order of the competent authority stating the legal grounds and justification for the action taken. No order of arrest or detention shall be issued against any person other than by the competent judicial authority, and unless same is preceded by a charge, accusation, or complaint for a credible party or by other evidence indicating the probable guilt of the accused; in cases of flagrante delicto, any person may arrest the offender and his accomplices, turning them over without delay to the nearest authorities. Only in urgent cases instituted by the public attorney without previous complaint or indictment and when there is no judicial authority available, may the administrative authorities, on their strictest accountability, order the detention of an accused person, turning him over immediately to the judicial authorities. Every search warrant, which can be issued only by judicial authority and which must be in writing, shall specify the place to be searched, the person or persons to be arrested, and the objects sought, the proceedings to be limited thereto; at the conclusion of which a detailed statement shall be drawn up in the presence of two witnesses proposed by the occupant of the place searched, or by the official making the search in his absence or should he refuse to do so. Administrative officials may enter private homes for the sole purpose of ascertaining whether the sanitary and police regulations have been complied with; and may demand to be shown the books and documents required to prove compliance with fiscal rulings, in which latter cases they must abide by the provisions of the respective laws and be subject to the formalities prescribed for cases of search.





Article 17. No one may be imprisoned for debts of a purely civil nature. No one may take the law into his own hands, or resort to violence in the enforcement of his rights. The courts shall be open for the administration of justice at such times and under such conditions as the law may establish; their services shall be gratuitous and all judicial costs are, accordingly, prohibited.





Article 18.(3) Arrest is permissible only for offenses punishable by imprisonment. The place of detention shall be completely separate from the place used for the serving of sentences. The federal and state governments shall organize the penal system withintheir respective jurisdictions on the basis of labor, training, and education as a means of social readjustment of the offender. Women shall serve their sentences in places separate from those intended for men for the same purpose. Governors of States, subject to the provisions of the respective local laws, may conclude agreements of a general nature with the federal government, under which offenders convicted for common offenses may serve their sentence in establishments maintained by the federal executive. The federal government and the state governments shall establish special institutions for the treatment of juvenile delinquents.





Article 19. No detention shall exceed three days without a formal order of commitment, which shall state the offense with which the accused is charged; the substance thereof; the place, time and circumstances of its commission; and the facts brought to light in the preliminary examination. These facts must be sufficient to establish the corpus delicti and the probable guilt of the accused. All authorities who order a detention or consent thereto, as well as all agents, subordinates, wardens, or jailers who execute it, shall be liable for any breach of this provision. The trial shall take place only for the offense or offenses set forth in the formal order of commitment. Should it develop, during the course of the proceedings, that another offense, different from that charged, has been committed, a separate accusation must be brought. This, however, shall not prevent the joinder of both proceedings, if deemed advisable. Any ill-treatment during arrest or confinement; any molesting without legal justification; any exaction or contribution levied in prison are abuses which shall be

punishable by law and repressed by the authorities.





Article 20. In every criminal trial the accused shall enjoy the following guarantees:





I.He shall be freed on demand and on furnishing bail which shall be fixed by the judge, according to his status and the gravity of the offense with which he is charged, provided, however, that such offense is not punishable with more than five years' imprisonment. No requisites shall be necessary other than placing the stipulated sum at the disposal of the proper authorities or giving adequate security or personal bond for acceptance of which the judge is responsible.The security or bond shall be not more than 250, 000 pesos except for offenses by which the offender profits or the victim suffers financially; for such offenses the security shall be at least three times the amount of the profit obtained or the damage suffered.





II.He may not be forced to be a witness against himself; wherefore denial of access or other means tending to this end is strictly prohibited.





III.He shall be publicly notified within forty-eight hours after being turned over to the judicial authorities of the name of his accuser and the nature of and cause for the accusation, so that he may be familiar with the offense with which he is charged, and reply thereto and make a preliminary statement.





IV.He shall be confronted with the witnesses against him, who shall testify in his presence if they are to be found in the place where the trial is held, so that he may cross-examine them in his defense.





V.All witnesses and other evidence which he may offer shall be heard in his defense, for which he shall be given the time which the law deems necessary for the purpose; he shall furthermore be assisted in securing the presence of the persons whose testimony he may request, provided they are to be found at the place where the trial is held.





VI.He shall be entitled to a public trial by a judge or jury of citizens who can read and write and are also residents of the place and district where the offense was committed, provided the penalty for such offense exceeds one year's imprisonment. The accused shall always be entitled to a trial by jury for all offenses committed by means of the press against the public peace or against the domestic or foreign safety of the nation.





VII.He shall be furnished with all information on record which he may request for his defense.





VIII.He shall be tried within four months, if charged with an offense whose maximum penalty does not exceed two years' imprisonment; and within one year, if the maximum penalty is greater.





IX.He shall be heard in his own defense, either personally or by counsel, or by both, as he may desire. Should he have no one to defend him, a list of official counsel shall be submitted to him, in order that he may choose one or more to act in his defense. If the accused does not wish to name any counsel for his defense, after being called upon to do so at the time of his preliminary examination, the court shall appoint his counsel for the defense. The accused may name his counsel immediately upon arrest, and shall be entitled to have him present at every stage of the trial; but he shall be obliged to make him appear as often as required by the court.





X.In no event may imprisonment or detention be extended through failure to pay counsel fees or for any other monetary obligation, on account of civil liability, or for other similar cause.





Nor shall detention be extended beyond the time set by law as the maximum for the offense charged.

The period of detention shall be reckoned as a part of the term of imprisonment imposed by sentence.





Article 21. The imposition of all penalties is an exclusive attribute of the judiciary. The prosecution of offenses pertains to the public prosecutor and to the judicial police, who shall be under the immediate command and authority of the public prosecutor. The punishment of violations of governmental and police regulations pertains to the administrative authorities, which punishment shall consist solely of imprisonment for a period not exceeding thirty-six hours or of a fine. Should the offender fail to pay the fine, it shall be substituted by a corresponding period of detention, which in no case may exceed fifteen days.If the offender is a day laborer or a workman, his punishment cannot consist of a fine exceeding the amount of his wages, for one week.





Article 22. Punishment by mutilation and infamy, branding, flogging, beating with sticks, torture of any kind, excessive fines, confiscation of property and any other unusual or extreme penalties are prohibited.





Attachment proceedings covering the whole or part of the property of a person made under judicial authority to cover payment of civil liability arising out of the commission of an offense or for the payment of taxes or fines shall not be deemed a confiscation of property.





Capital punishment for political offenses is likewise prohibited; as regards other offenses, it can only be imposed for high treason committed during a foreign war, parricide, murder that is treacherous, premeditated, or committed for profit, arson, abduction, highway robbery, piracy, and grave military offenses.





Article 23. No criminal trial shall have more than three instances. No person, whether acquitted or convicted, can be tried twice for the same offense. The practice of absolving from the instance(5) is prohibited.





Article 24. Everyone is free to embrace the religion of his choice and to practice all ceremonies, devotions, or observances of his respective faith, either in places of public worship or at home, provided they do not constitute an offense punishable by law.





Every religious act of public worship must be performed strictly inside places of public worship, which shall at all times be under governmental supervision.





Article 25. Sealed correspondence sent through the mail shall be exempt from search and its violation shall be punishable by law.





Article 26. No member of the army shall in time of peace be quartered in private dwellings without the consent of the owner, nor may he impose any obligation whatsoever. In time of war the military may demand lodging, equipment, provisions, and other assistance, in the manner laid down in the respective martial law.





Article 27. Ownership of the lands and waters within the boundaries of the national territory is vested originally in the Nation, which has had, and has, the right to transmit title thereof to private persons, thereby constituting private property. Private property shall not be expropriated except for reasons of public use and subject to payment of indemnity. The Nation shall at all times have the right to impose on private property such limitations as the public interest may demand, as well as the right to regulate the utilization of natural resources which are susceptible of appropriation, in order to conserve them and to ensure a more equitable distribution of public wealth. With this end in view, necessary measures shall be taken to divide up large landed estates; to develop small landed holdings in operation; to create new agricultural centers, with necessary lands and waters; to encourage agriculture in general and to prevent the destruction of natural resources, and to protect property from damage to the detriment of society. Centers of population which at present either have no lands or water or which do not possess them in sufficient quantities for the needs of their inhabitants, shall be entitled to grants thereof, which shall be taken from adjacent properties, the rights of small landed holdings in operation being respected at all times.





In the Nation is vested the direct ownership of all natural resources of the continental shelf and the submarine shelf of the islands; of all minerals or substances, which in veins, ledges, masses or ore pockets, form deposits of a nature distinct from the components of the earth itself, such as the minerals from which industrial metals and metalloids are extracted; deposits of precious stones, rock-salt and the deposits of salt formed by sea water; products derived from the decomposition of rocks, when subterranean works are required for their extraction; mineral or organic deposits of materials susceptible of utilization as fertilizers; solid mineral fuels; petroleum and all solid, liquid, and gaseous hydrocarbons; and the space above the national territory to the extent and within the terms fixed by international law. In the Nation is likewise vested the ownership of the waters of the territorial seas, within the limits and terms fixed by international law; inland marine waters; those of

lagoons and estuaries permanently or intermittently connected with the sea; those of natural, inland lakes which are directly connected with streams having a constant flow; those of rivers and their direct or indirect tributaries from the point in their source where the first permanent, intermittent, or torrential waters begin, to their mouth in the sea, or a lake, lagoon, or estuary forming a part of the public domain; those of constant or intermittent streams and their direct or indirect tributaries, whenever the bed of the stream, throughout the whole or a part of its length, serves as a boundary of the national territory or of two federal divisions, or if it flows from one federal division to another or crosses the boundary line of the Republic; those of lakes, lagoons, or estuaries whose basins, zones, or shores are crossed by the boundary lines of two or more divisions or by the boundary line of the Republic and a neighboring country or when the shoreline serves as the boundary between two federal divisions or of the Republic and a neighboring country; those of springs that issue from beaches, maritime areas, the beds, basins, or shores of lakes, lagoons, or estuaries in the national domain; and waters extracted from mines and the channels, beds, or shores of interior lakes and streams in an area fixed by law. Underground waters may be brought to the surface by artificial works and utilized by the surface owner, but if the public interest so requires or use by others is affected, the Federal Executive may regulate its extraction and utilization, and even establish prohibited areas, the same as may be done with other waters in the public domain. Any other waters not included in the foregoing enumeration shall be considered an integral part of the property through which they flow or in which they are deposited, but if they are located in two or more properties, their utilization shall bedeemed a matter of public use, and shall be subject to laws enacted by the States. In those cases to which the two preceding paragraphs refer, ownership by the Nation is inalienable and imprescriptible, and the exploitation, use, or appropriation of the resources concerned, by private persons or by companies organized according to Mexican laws, may not be undertaken except through concessions granted by the Federal Executive, in accordance with rules and conditions established by law. The legal rules relating to the working or exploitation of the minerals and substances referred to in the fourth paragraph shall govern the execution and proofs of what is carried out or should be carried out after they go into effect, independent of the date of granting the concessions, and their nonobservance will be grounds for cancellation thereof. The Federal Government has the power to establish national reserves and to abolish them. The declarations pertaining thereto shall be made by the Executive in those cases and conditions prescribed by law. In the case of petroleum, and solid, liquid, or gaseous hydrocarbons no concessions or contracts will be granted nor may those that have been granted continue, and the Nation shall carry out the exploitation of these products, in accordance with the provisions indicated in the respective regulatory law. It is exclusively a function of the general Nation to conduct, transform, distribute, and supply electric power which is to be used for public service. No concessions for this purpose will be granted to private persons and the Nation will make use of the property and natural resources which are required for these ends. Legal capacity to acquire ownership of lands and waters of the Nation shall be governed by the following provisions:





I.Only Mexicans by birth or naturalization and Mexican companies have the right to acquire ownership of lands, waters, and their appurtenances, or to obtain concessions for the exploitation of mines or of waters. The State may grant the same right to foreigners, provided they agree before the Ministry of Foreign Relations to consider themselves as nationals in respect to such property, and bind themselves not to invoke the protection of their governments in matters relating thereto; under penalty, in case of noncompliance with this agreement, of forfeiture of the property acquired to the Nation. Under no circumstances may foreigners acquire direct ownership of lands or waters within a zone of one hundred kilometers along the frontiers and of fifty kilometers along the shores of the country.





The State, in accordance with its internal public interests and with principles of reciprocity, may in the discretion of the Secretariat of Foreign Affairs authorize foreign states to acquire, at the permanent sites of the Federal Powers, private ownership of real property necessary for the direct services of their embassies or legations.





II.Religious institutions known as churches, regardless of creed, may in no case acquire, hold, or administer real property or hold mortgages thereon; such property held at present either directly or through an intermediary shall revert to the Nation, any person whosoever being authorized to denounce any property so held. Presumptive evidence shall be sufficient to declare the denunciation well founded. Places of public worship are the property of the Nation, as represented by the Federal Government, which shall determine which of them may continue to be devoted to their present purposes. Bishoprics, rectories, seminaries, asylums, and schools belonging to religious orders, convents, or any other buildings built or intended for the administration, propagation, or teaching of a religious creed shall at once become the property of the Nation by inherent right, to be used exclusively for the public services of the Federal or State Governments, within their respective jurisdictions. All places of public worship hereafter erected shall be the property of the Nation.





III.Public or private charitable institutions for the rendering of assistance to the needy, for scientific research, the diffusion of knowledge, mutual aid to members, or for any other lawful purpose, may not acquire more real property than actually needed for their purpose and immediately and directly devoted thereto; but they may acquire, hold, or administer mortgages on real property provided the term thereof does not exceed ten years. Under no circumstances mayinstitutions of this kind be under the patronage, direction, administration, charge, or supervision of religious orders or institutions, or of ministers of any religious sect or of their followers, even though the former or the latter may not be in active service.

IV.Commercial stock companies may not acquire, hold, or administer rural properties. Companies of this kind that are organized to operate any manufacturing, mining, or petroleum industry or for any other purpose that is not agricultural, may acquire, hold, or administer lands only of an area that is strictly necessary for their buildings or services, and this area shall be fixed in each particular case by the Federal or State Executive.

V.Banks duly authorized to operate in accordance with the laws on credit institutions may hold mortgages on urban and rural property in conformity with the provisions of such laws but they may not own or administer more real property than is actually necessary for their direct purpose.

VI.With the exception of the corporate entities referred to in clauses III, IV, and V hereof, and the centers of population which by law or in fact possess a communal status or centers that have received grants or restitutions or have been organized as centers of agricultural population, no other civil corporate entity may hold or administer real property or hold mortgages thereon, with the sole exception of the buildings intended immediately and directly for the purposes of the institution. The States, the Federal District, and the Territories, and all Municipalities in the Republic, shall have full legal capacity to acquire and hold all the real property needed to render public services. The federal and state laws, within their respective jurisdictions, shall determine in what cases the occupation of private property shall be considered to be of public utility; and in accordance with such laws, the administrative authorities shall issue the respective declaration. The amount fixed as compensation for the expropriated property shall be based on the value recorded in assessment or tax offices for tax purposes, whether this value had been declared by the owner or tacitly accepted by him by having paid taxes on that basis. The increased or decreased value of such private property due to improvements or depreciation which occurred after such assessment is the only portion of the value that shall be subject to the decision of experts and judicial proceedings. This same procedure shall be followed in the case of property whose value is not recorded in the tax offices. The exercise of actions pertaining to the Nation by virtue of the provisions of this article shall be made effective by judicial procedure, but during these proceedings and by order of the proper courts, which must render a decision within a maximum of one month, the administrative authorities shall proceed without delay to occupy, administer, auction, or sell the lands and waters in question and all their appurtenances, and in no case may the acts of such authorities be set aside until a final decision has been rendered.

VII. The centers of population which, by law or in fact, possess a communal status shall have legal capacity to enjoy common possession of the lands, forests, and waters belonging to them or which have been or may be restored to them. All questions, regardless of their origin, concerning the boundaries of communal lands, which are now pending or that may arise hereafter between two or more centers of population, are matters of federal jurisdiction. The Federal Executive shall take cognizance of such controversies and propose a solution to the interested parties. If the latter agree thereto, the proposal of the Executive shall take full effect as a final decision and shall be irrevocable; should they not be in conformity, the party or parties may appeal to the Supreme Court of Justice of the Nation, without prejudice to immediate enforcement of the presidential proposal. The law shall specify the brief procedure to which the settling of such controversies shall conform.

VIII.The following are declared null and void:

a.All transfers of the lands, waters, and forests of villages, rancherías, groups, or communities made by local officials (jefes políticos), state governors, or other local authorities in violation of the provisions of the Law of June 25, 1856, and other related laws and rulings.

b.All concessions, deals or sales of lands, waters, and forests made by the Secretariat of Development, the Secretariat of Finance, or any other federal authority from December 1, 1876 to date, which encroach upon or illegally occupy communal lands (ejidos), lands allotted in common, or lands of any other kind belonging to villages, rancherias, groups or communities, and centers of population.

c.All survey or demarcation-of-boundary proceedings, transfers, alienations, or auction sales effected during the period of time referred to in the preceding sub-clause, by companies, judges, or other federal or state authorities entailing encroachments on or illegal occupation of the lands, waters, or forests of communal holdings (ejidos), lands held in common, or other holdings belonging to centers of population. The sole exception to the aforesaid nullification shall be the lands to which title has been granted in allotments made in conformity with the Law of June 25, 1856, held by persons in their own name for more than ten years and having an area of not more than fifty hectares.



IX.Divisions or allotments of land among the inhabitants of a given center of population which, although apparently legitimate are not so, due to a mistake or defect, may be annulled at the request of three fourths of the residents holding one fourth so divided, or one fourth of such residents holding three fourths of the lands.



X.Centers of population which lack communal lands or which are unable to have them restored to them due to lack of titles, impossibility of identification, or because they had been legally transferred, shall be granted sufficient lands and waters to constitute them, in accordance with the needs of the population; but in no case shall they fail to be granted the area needed, and for this purpose the land needed shall be expropriated, at the expense of the Federal Government, to be taken from lands adjoining the villages in question. The area or individual unit of the grant shall hereafter be not less than ten hectares of moist or irrigated land, or in default of such land its equivalent in other types of land in accordance with the third paragraph of section XV of this article.



XI.For the purpose of carrying out the provisions of this article and of regulating laws that may be enacted, the following are established:

a.A direct agency of the Federal Executive entrusted with the application and enforcement of the agrarian laws;

b.An advisory board composed of five persons to be appointed by the President of the Republic and who shall perform the functions specified in the organic laws;

c.A mixed commission composed of an equal number of representatives of the Federal Government, the local governments, and a representative of the peasants, to be appointed in the manner set forth in the respective regulating law, to function in each State, Territory, and the Federal District, with the powers and duties set forth in the organic and regulatory laws;

d.Private executive committees for each of the centers of population that are concerned with agrarian cases;

e.A communal office for each of the centers of population that possess communal lands.

XII.Petitions for a restitution or grant of lands or waters shall be submitted directly to the state and territorial governors. The governors shall refer the petitions to the mixed commissions, which shall study the cases during a fixed period of time and render a report; the State governors shall approve or modify the report of the mixed commission and issue orders that immediate possession be given to areas which they deem proper. The case shall then be turned over to the Federal Executive for decision. Whenever the governors fail to comply with the provisions of the preceding paragraph, within the peremptory period of time fixed by law, the report of the mixed commission shall be deemed rejected and the case shall be referred immediately to the Federal Executive. Inversely, whenever a mixed commission fails to render a report during the peremptory time limit, the Governor shall be empowered to grant possession of the area of land he deems appropriate.

XIII.The agency of the Executive and the Agrarian Advisory Board shall report on the approval, rectification, or modification of the reports submitted by the mixed commissions, containing the changes made therein by the local governments, and so notify the President of the Republic, who as the supreme agrarian authority will render a decision.



XIV.Landowners affected by decisions granting or restoring communal lands and waters to villages, or who may be affected by future decisions, shall have no ordinary legal right or recourse and cannot institute amparo proceedings.Persons affected by such decisions shall have solely the right to apply to the Federal Government for payment of the corresponding indemnity. This right must be exercised by the interested parties within one year counting from the date of publication of the respective resolution in the Diario Oficial. After this period has elapsed, no claim is admissible. Owners or occupants of agricultural or stockraising properties in operation who have been issued or to whom there may be issued in the future certificates of non-affectability may institute amparo proceedings against any illegal deprivation or agrarian claims on their lands or water.



XV.The mixed commissions, the local governments and any other authorities charged with agrarian proceedings cannot in any case affect small agricultural or livestock properties in operation and they shall incur liability for violations of the Constitution if they make grants which affect them. Small agricultural property is that which does not exceed one hundred hectares of first-class moist or irrigated land or its equivalent in other classes of land, under cultivation. To determine this equivalence one hectare of irrigated land shall be computed as two hectares of seasonal land; as four of good quality agostadero and as eight as monte or arid pasturage. Also to be considered as small holdings are areas not exceeding two hundred hectares of seasonal lands or pasturage susceptible of cultivation; or one hundred fifty hectares of land used for cotton growing if irrigated from fluvial canals or by pumping; or three hundred, under cultivation, when used for growing bananas, sugar cane, coffee, henequen, rubber, coconuts, grapes, olives, quinine, vanilla, cacao, or fruit trees. Small holdings for stockraising are lands not exceeding the area necessary to maintain up to five hundred head of cattle (ganado mayor) or their equivalent in smaller animals (ganado menor - sheep, goats, pigs) under provisions of law, in accordance with the forage capacity of the lands. Whenever, due to irrigation or drainage works or any other works executed by the owners or occupants of a small holding to whom a certificate of non-affectability has been issued, the quality of the land is improved for agricultural or stockraising operations, such holding shall not be subject to agrarian appropriation even if, by virtue of the improvements made, the maximums indicated in this section are lowered, provided that the requirements fixed by law are met.



XVI.Lands which are subject to individual adjudication must be partitioned precisely at the time the presidential order is executed, according to regulatory laws.



XVII.The Federal Congress and the State Legislature, within their respective jurisdictions, shall enact laws to fix the maximum area of rural property, and to carry out the subdivision of the excess lands, in accordance with the following bases:

a.In each State, Territory, or the Federal District, there shall be fixed a maximum area of land of which a single individual or legally constituted society may be the owner.

b.The excess over the fixed area shall be subdivided by the owner within the time fixed by the local law, and these parcels shall be offered for sale under terms approved by the governments, in accordance with the aforementioned laws.

c.If the owner should oppose the subdivision, it shall be carried out by the local government, by expropriation.

d.The value of the parcels shall be paid by annual installments which will amortize principal and interest, at an interest rate not exceeding 3% per annum.

e.Owners shall be required to receive bonds of the local Agrarian Debt to guarantee payment for the property expropriated. For this purpose, the Federal Congress shall enact a law empowering the States to create their Agrarian Debt.

f.No subdivision can be sanctioned which fails to satisfy the agrarian needs of neighboring settlements (poblados inmediatos). Whenever subdivision projects are to be executed, the agrarian claims must be settled within a fixed period.

g.Local laws shall organize the family patrimony, determining what property shall constitute it, on the basis that it shall be inalienable and shall not be subject to attachment or encumbrance of any kind.



XVIII.All contracts and concessions made by former Governments since the year 1876, which have resulted in the monopolization of lands, waters, and natural resources of the Nation, by a single person or company, are declared subject to revision, and the Executive of the Union is empowered to declare them void whenever they involve serious prejudice to the public interest.



Article 28. In the United Mexican States there shall be no monopolies or estancos of any kind; nor exemption from taxes; nor prohibitions under the guise of protection to industry; excepting only those relating to the coinage of money, the mails, telegraph, and radiotelegraphy, to the issuance of paper money by a single bank to be controlled by the Federal Government, and to the privileges which for a specified time are granted to authors and artists for the reproduction of their works, and to those which, for the exclusive use of their inventions, may be granted to inventors and those who perfect some improvement. Consequently, the law shall punish severely and the authorities shall effectively prosecute every concentration or cornering in one or a few hands of articles of prime necessity for the purpose of obtaining a rise in prices; every act or proceeding which prevents or tends to prevent free competition in production, industry or commerce, or services to the public; every agreement or combination, in whatever manner it may be made, of producers, industrialists, merchants, and common carriers, or those engaged in any other service, to prevent competition among themselves and to compel consumers to pay exaggerated prices; and in general, whatever constitutes an exclusive and undue advantage in favor of one or more specified persons and to the prejudice of the public in general or of any social class. Associations of workers, formed to protect their own interests, do not constitute monopolies. Nor do cooperative associations or societies of producers constitute monopolies, which in defense of their interests or of the general interest, sell directly in foreign markets the domestic or industrial products which are the main source of wealth in the region in which they are produced, and which are articles of prime necessity, provided that such associations are under the supervision and protection of the Federal or State Governments and that they were previously duly authorized for the purpose by the respective legislatures, which latter of themselves or on proposal of the Executive may, when the public need so requires, repeal the authorizations

granted for the formation of the associations in question.



Article 29. In the event of invasion, serious disturbance of the public peace, or any other event which may place society in great danger or conflict, only the President of the Mexican Republic, with the consent of the Council of Ministers and with the approval of the Federal Congress, and during adjournments of the latter, of the Permanent Committee, may suspend throughout the country or in a determined place the guarantees which present an obstacle to a rapid and ready combatting of the situation; but he must do so for a limited time, by means of general preventive measures without such suspensions being limited to a specified individual. If the suspension should occur while the Congress is in session, the latter shall grant such authorizations that it deems necessary to enable the Executive to meet the situation. If the suspension occurs during a period of adjournment, the Congress shall be convoked without delay in order to grant them.
