Guide to basic research on Mexican law in Tarlton Law Library
Prepared by Jonathan Pratter, Foreign & International Law Librarian
(Revised June 2009)
I. Overview
The Tarlton Law Library has a major collection of Mexican legal materials. The collection is in more than one place in the Law Library. This guide is intended to bring together references for researching Mexican law in the Law Library, as well as electronically (Internet, Westlaw, Lexis).
The main area of the Law Library holding Mexican legal materials is KGF 10 to KGF 9900 on stacks 647 & 648 (6th floor).
II. Primary sources
National Constitution
- Constitución Política de los Estados Unidos Mexicanos KGF 2914 1917 A6 2007
- A World Wide Web version of the Constitución current to May 2009 and authoritative (produced by the national Chamber of Deputies) is available at the website of the Chamber of Deputies (http://www.diputados.gob.mx/LeyesBiblio/pdf/1.pdf).
- Another Web version of the Constitución also current to May 2009, also authoritative (produced by the UNAM Instituto de Investigaciones Jurídicas) is available on the Instituto's website, InfoJUS (http://info4.juridicas.unam.mx/ijure/tcfed/8.htm?s=).
- A recent English translation (current to 2007) is available in the hard copy set Constitutions of the Countries of the World. K 3157 E5 B5
- A translation on the Web dates from 2005 (http://www.bibliojuridica.org/doctos/1/12/12.pdf).
- Do not use the translation at www.ilstu.edu/class/hist263/docs/1917const.html. It is based on a grossly outdated text. (Caution: This is the first text that appears from a Google search on Mexico and constitution. Another caution: The Wikipedia entry "Constitution of Mexico" is a paraphrase, not a translation.)
State constitutions
- A collection of state constitutions for all 31 states, including the Statute of Government for the Federal District, is available on the InfoJUS website (http://www.juridicas.unam.mx/infjur/leg/cnsinfo).
- The hard copy Constitutions of Dependencies and Territories K3157 C59 has English translations of the constitutions of Baja California Norte, Hidalgo, Jalisco, Mexico (State), Michoacán, Nuevo León, Tamaulipas, and Yucatán. However, several of these translations are outdated.
National legislation
- The Diario Oficial de la Federación is the daily official gazette of the federal government. It publishes laws and regulations enacted by the federal government. The Diario is available in the following ways:
--From 1967 to 2000, in paper KGF 16 M495, closed stacks
--From 1917 to the present on a subscription basis from the website of the Diario Oficial (http://www.dof.gob.mx).
--Without a subscription from the same website:
- 2005-present in PDF;
- Recent numbers, including the current day, in Word and HTML formats, in addition to PDF.
--From July 1995 to present, on Westlaw (MX-DIARIO).
- The Law Library maintains a large collection of current federal legislation in hard copy in the KGF section. Examples are:
- Código de Comercio (2007)
- Código Federal de Instituciones y Procedimientos Electorales (2006)
- Ley de Amparo y Disposiciones Complementarias (2007)
- The Chamber of Deputies of the Mexican Congress maintains a website (http://www.diputados.gob.mx/LeyesBiblio/index.htm)with over 250 federal codes and laws in current versions. This site also has over 80 of the important reglamentos de leyes federales (regulations to the federal legislation).
- A similar collection is available on the InfoJUS website (http://info4.juridicas.unam.mx/ijure/fed).
- Lexis has several files of Mexican legislative materials under Legal > Find Laws by Country or Region > Mexico. These files vary greatly in quality and utility. Some are well-organized others are not. Some are being updated; others are not. One file is the Diario Oficial, although it is not as well formatted as on Westlaw. Lexis also has a file of jurisprudencia for the Supreme Court, as well as for the Tribunal Fiscal de la Federación.
Finding Normas Oficiales Mexicanas (NOM)
- These are technical standards promulgated by the Mexican government. They are published officially in the Diario Oficial and have the force of law. The Secretaría de Economía makes available for free on the Web a Catálogo de Normas Oficiales Mexicanas (http://www.economia-noms.gob.mx).
National legislation in English translation
- Mexican legislation in English translation is scattered in many sources. Some are mentioned here. For further assistance finding translations see Jonathan Pratter, Foreign & International Law Librarian, 6.201 (6th floor).
- Foreign Law Guide (www.foreignlawguide.com); Mexico entry. (The Law Library subscribes to this; UT EID and password required.) This is a valuable resource for finding information on legislation in Mexico, including translations.
- Federal Civil Code of Mexico KGF 404.32 A52 2003 and KGF 404.32 V37 2005. These are the recommended translations of this recently enacted civil code.
- Mexican Law Library: Commercial Codes KGF 1054 1997. These are now somewhat dated translations of business-related legislation.
State legislation
- The section KGF 6211 to KGF 9390 (stack 648) is devoted to law of the Mexican states and the Federal District. Current collections of the major codes are maintained.
- A selection of state legislation is available on the InfoJUS website (http://info4.juridicas.unam.mx/adprojus/leg).
- The Mexican states and the Federal District are now posting a good deal of legislation on their websites.
Use the collection of links to state governments at the website of the Chamber of Deputies (http://www.diputados.gob.mx/LeyesBiblio/gobiernos.htm).
National judicial decisions
- Semanario Judicial de la Federación KGF 72 A2 1995 (stack
648) is the only regularly published reporter of judicial decisions in Mexico. It covers the decisions of the Suprema Corte de Justicia de la Nación (Supreme Court of México) and the Tribunales Colegiados de Circuito (federal intermediate courts of appeals).
--Tarlton Law Library is one of the few law libraries in the U.S. with a current and complete collection of the Semanario.
- IUS 2007 (www.scjn.gob.mx/ius2006/) is the database of the Suprema Corte containing what are called “tesis de
jurisprudencia” and “tesis aisladas." These are summaries of decisions. In addition to "tesis," IUS 2007 (which is actually current to 2009) now includes a selection of "ejecutorias" (full text decisions).
- "Jurisprudencia" is a category of decisions with precedential effect. In hard copy the jurisprudencia is collected in the Apéndice al Semanario KGF 70.2 M48 2000 (stack 648).
- Decisions of the state appellate courts generally are are very hard to find outside Mexico. The best opportunity for finding state appellate decisions is through the collection of links to state governments at the Chamber of Deputies website noted above.
