Constitución Política de los Estados Unidos Mexicanos
The constitution currently in force was adopted in 1917. Given that the constitution is amended so frequently, it is important to consult an up-to-date text. The versions on the Web cited below are current.
Semanario Judicial de la Federación 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).
Beginning in 2012, the Semanario began its tenth "epoch." Note that the Semanario is now posted in full text PDF on the website of the Supreme Court, going back to the issue for March 2011. (Each monthly issue is over 2,000 pages and so will take several minutes to load.)
IUS is the database of the Supreme Court containing what are called “tesis de jurisprudencia.” These are summaries ("tesis") of decisions. "Jurisprudencia" is the category of decisions having precedential effect. In addition to "tesis de jurisprudencia," IUS now includes some "ejecutorias" (full text decisions). In hard copy the jurisprudencia is collected, but only up to 2000, in the Apéndice al Semanario (KGF 72.5 A64 2000).
Decisions of the state appellate courts are impossible to find outside Mexico.
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. It is available at the website of the Diario Oficial.
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 (ask for him at the Circulation Desk).
The call number range KGF 6211 to KGF 9390 is devoted to law of the Mexican states and the Federal District.
