In preparing chapters II and III of this manual, the authors made reference to Guidelines for Prosecution in Mexico, a handbook on Article 4 murder prosecutions published by the California Attorney General
When a Mexican national commits a crime in the United States and then flees to Mexico, an American prosecutor has two realistic options:
The first option, extradition, is always the preferred avenue. When an individual accused of a crime is extradited to the United States, he or she will be tried, and if convicted, sentenced in the jurisdiction where the crime was committed.
Mexican authorities rarely refuse extradition of an American citizen to the United States. Likewise, the United States commonly returns Mexican nationals for crimes committed in that country. However, complications with the extradition treaty arise when
Mexico is requested to extradite its own nationals. Extradition may not always be a viable option for American prosecutors seeking to bring a Mexican criminal to justice.
A second option, an "Article 4 prosecution," is so termed because of the unique statute of the Mexican Federal Penal Code that permits the prosecution of Mexican citizens who commit crimes in foreign territories. A prosecution of a Mexican national under Article 4 of the Mexican Federal Penal Code may be the best option available to American prosecutors.
The principal barriers to Article 4 prosecution in this state appear to be uncertainty about procedure and lack of familiarity with Mexican law. This manual is designed to facilitate the use of Article 4 by law enforcement authorities and to outline the assistance available through the Texas Attorney General's International Prosecutions Unit.
Since establishing its International Prosecutions Unit in 1994, the Texas Attorney General's has worked with the Office of the Attorney General of Mexico to bring numerous dangerous individuals to justice. Both offices have an established record of cooperation in foreign prosecutions. Texas prosecutors are now able to seek justice in cases that in the past might have remained unresolved.
Foreign Prosecutions: Case Criteria
The Mexican judicial system varies dramatically from those in Texas, other American States, and U.S. federal courts. One of the fundamental differences is Mexico's ability to prosecute one of its citizens for committing a crime outside its national boundaries. The Mexican Federal Penal Code, under Article 4, allows for the domestic prosecution of Mexican nationals who commit crimes in a foreign country--in this case the United States--and flee to Mexico in search of a safe haven from prosecution. Since such prosecutions do not take place in accordance with an international treaty, (in which case U.S. federal authorities would be obligated to intervene) under Article 4 it is possible for a state agency in the United States to request that a criminal be arrested and prosecuted in Mexico. For Texas, such requests have been traditionally handled by the Attorney General who works with Texas prosecutors to present requests under Article 4 to the corresponding authorities in Mexico.
Article 4 is a very concise and clear law. Translated, it reads:
Crimes committed in a foreign territory by a Mexican against a Mexican or against a foreigner, or by a foreigner against a Mexican, will be punished in the Republic of Mexico, in accordance with federal law, if the following requirements are met:
- That the accused be in the Republic of Mexico;
- That the prisoner has not been definitively tried in the country where he committed the crime, and;
- That the infraction with which he is charged be a crime both in the country where it was committed and in the Republic of Mexico.
Given the differences in the legal systems and substantive laws of our respective countries, coupled with the guidelines set forth in Article 4 of the Mexican Federal Penal Code, not all cases are appropriate for this type of prosecution. The Attorney General's International Prosecutions Unit explores all possible avenues prior to determining whether a case is suitable for Article 4 prosecution.
Extradition of United States Citizens Versus Mexican Citizens
The United States and Mexico signed an extradition treaty on May 4, 1978 that provides for the return of individuals who have committed crimes and fled across the United States-Mexico border.
In every case presented for review by the International Prosecutions Unit, the option of extradition is considered.
However, like most extradition agreements, the treaty between the United States and Mexico does not obligate either party to hand over its own nationals. In recent years, extraditions of Mexican nationals to face trial in the United States have been the exception rather than the norm. Thus, if it is determined that a suspect is a citizen of that country, an Article 4 prosecution is generally the best way to proceed. But if the suspect is indeed an American citizen, in most cases an extradition request will be honored by Mexico. The International Prosecutions Unit is also available to help Texas and other American prosecutors to coordinate with U.S. and Mexican federal authorities in the presentation of extradition requests.
The extradition process is useful for securing the return of an American suspect to the United States, at the United States' request, if the individual is wanted for committing a crime in United States territory.
International Extradition Requires Federal Involvement
Prosecutors who are reluctant to forego domestic prosecution of Mexican nationals should be aware that extradition is not a quicker, easier alternative to preparing for prosecution under Mexican law. An extradition request calls for equally thorough case preparation and requires the use of official diplomatic channels. A request to Mexico under the United States-Mexico Extradition Treaty must be approved by the United States Department of Justice and tendered by the Department of State.
Presenting A Request For Prosecution In Mexico
As in a case for extradition, Article 4 requires that the criminal act for which a Mexican prosecution is sought be recognized as a criminal offense in both Mexico and the requesting country. These are essentially the same offenses for which extradition may be requested. While Article 4 has been traditionally invoked only in cases of serious crimes such as murder, kidnaping, and rape, prosecutors should consider lesser crimes that may be added to principal charges and extend the length of a sentence in Mexico.
Article 4, like extradition, requires evidence that is sufficient to warrant prosecution in Texas. Prosecutors should carefully review prospective Article 4 requests to ensure that cases are well developed and investigated before Article 4 prosecution is requested. Texas prosecutors should keep in mind that Mexican federal authorities are not obligated to accept and prosecute Article 4 cases. Notwithstanding, the Office of the Attorney General of Mexico has a long history of cooperation with U.S. border states in handling such cases. To ensure continued future cooperation, Texas prosecutors should consider filing only their strongest cases.
Furthermore, Article 4 is not applicable if the fugitive has been definitively tried in the United States. Under Mexican law, a person is considered to have been definitively tried when he or she has been tried and convicted or acquitted, has been sentenced if convicted, and has no appeal pending. However, there are many instances where domestic prosecution has been initiated, and Article 4 may still be applicable. If, for example, an individual has been tried and convicted in the United States but has fled to Mexico during the pendency of the appeal, he or she can still be prosecuted under Article 4. The same is true for people who escape while free on bond pending their trial.
If a fugitive has been tried and convicted but has fled to Mexico before sentencing or incarceration, Mexican law will permit Mexican authorities to incarcerate the defendant in a Mexican prison based upon the Texas conviction. In addition, a fugitive may be charged for Unlawful Flight to Avoid Prosecution, a United States federal offense, once he or she crosses the border.
Securing Arrest Through Article 4
As with extradition, arrest under Article 4 prosecution is initiated through a formal request. The time constraints for arresting a fugitive pursuant to an Article 4 request are more stringent than those for an arrest pursuant to an extradition request. Whereas a person may be held under provisional arrest for 60 days while an extradition request is prepared, a fugitive may be held for only four days before a formal request is presented pursuant to Article 4.
Mexican law requires that an arresting authority in Mexico surrender any suspect to the federal judicial police within 24 hours of his or her arrest. Once a suspect is in custody, the Mexican federal prosecutor either rejects or files the complaint with the federal court. The federal court then has 72 hours to determine whether the complaint has merit. This is a total of 96 hours, including weekends and Mexican holidays, between arrest and either the release of the fugitive or the acceptance of the complaint for prosecution. It is therefore imperative that a prosecutor submit a complete case file along with the request for an Article 4 prosecution.
Additional information on arrest and detention can be found in Chapter IV, which gives an overview of the Mexican criminal justice system.
Locating the Fugitive in Mexico
While the Texas prosecutor is conducting an investigation in the United States, he or she should attempt to ascertain a location for the fugitive or his or her family members, friends, or accomplices in Mexico. However, Texas authorities should never conduct an investigation in Mexico without the prior knowledge and consent of Mexican authorities. Conducting an unauthorized investigation in Mexico is a serious violation of Mexican law.
The United States-Mexico Mutual Legal Assistance Treaty, included in the Appendix, outlines procedures for the transfer of evidence between the nations. This may provide an avenue for allowing a Texas investigator to accompany his Mexican counterpart, as an observer, in the gathering of information in Mexico. For more information on the Treaty or to find out how to conduct a lawful investigation in Mexico, Texas law enforcement officials should contact the Attorney General's International Prosecutions Unit.
Sentencing and Time Served Under Article 4
Texas and American prosecutors will find that sentences in Mexico are generally comparable to those in Texas. The single notable exception involves juvenile offenders, which is discussed in Chapter IV.
For the most part, however, a person who is prosecuted under Article 4 will receive punishment as great as that which he or she would receive as a result of a domestic prosecution. It should be noted that capital punishment is not an option in Mexico. Once the suspect in a Texas capital crime has fled to Mexico, capital punishment is effectively out of reach. Mexico will not extradite anyone wanted for a capital offense, regardless of nationality, unless United States authorities adequately assure Mexican authorities that they will not seek the death penalty.
Taking Parole Into Account
Time actually served in Mexico differs significantly from time actually served in Texas. Parole does not exist under Mexican law; therefore, Mexican officials rarely commute or lessen sentences. Once sentenced in Mexico, a criminal may not have his or her term diminished for good behavior, as is typically the case in Texas.

The Article 4 Case File
Filing a request for foreign prosecution under the provisions of Article 4 of the Mexican Penal Code requires submitting a comprehensive case file. This file contains all necessary supporting documentation for the prosecution in Mexico and is presented to the Mexican federal authorities at the time of the formal request for prosecution.
In some cases, Mexican authorities may ask for additional testimony or evidence after reviewing the case file and the formal request for prosecution. It is therefore advisable that prosecutors make every effort when preparing the case file to anticipate and provide all necessary documents, evidence, and other supporting materials.
This chapter provides detailed instructions for preparing the case file for an Article 4 prosecution. Agencies wishing to file a request for Article 4 prosecution should contact the International Prosecutions Unit at (512) 463-2170 for technical and logistical assistance.
Contents of the Article 4 Case File
The Article 4 case file is similar to a file prepared by a prosecuting attorney prior to prosecuting an individual in a Texas court. It must include the following documentation:
The above must be duly translated by a reputable professional translator. Once translated, the entire case file must be legalized.
Detailed instructions for all of the necessary steps, including translation of the file, are provided in this chapter and Chapter III. The case file must be accompanied by several letters and documents. Example are included in figure II-1.
The Prosecuting Attorney's Affidavit and Texas Statutes
The prosecuting attorney with jurisdiction in the case must prepare an affidavit that names the suspect, provides a brief summary of the facts, and specifies all charges and their penalties under Texas law. The affidavit, which should be executed before a judge, should clearly identify and attest to the authenticity of each attached document and state that the suspect has not been previously arrested or tried in the United States. This documentation, along with all other requests and contents of the case file, is to be included in the Spanish translation of the case file.
Authenticated copies of all state statutes that authorize criminal prosecution in Texas must be included in the case file. This is necessary so that Mexican prosecutors can determine whether the case meets the requirement of Article 4, Subsection III: that the offense be a crime in both countries. The prosecuting attorney is urged to consult with the International Prosecutions Unit to determine which Texas statutes to include.
The Texas prosecutor must authenticate state statutes by filing a motion requesting that a district court judge take judicial notice of the relevant statutes and enter an order authenticating the same. Such an order should comply with the self-authentication provisions of Tex. Rule Crim. Evid. 902(1). An example of the motion and order authenticating statutes are supplied in Figure II-1.
Police and Technical Reports
Copies of all pertinent crime reports, investigative reports, and related documents must be included in the case file. These documents include, but are not limited to:
If possible (and applicable), the victim's attending physician should address injuries contributing to death. The following should also be included in murder prosecution case files:
All reports must contain the signature of the reporting officer. Originals of the reports, statements, documents, and evidence should be retained by the requesting agency and not submitted to the Mexican prosecutor. These materials may be needed for Texas prosecution if the suspect is apprehended in the United States. The head of the investigating agency (sheriff or chief of police) must certify by letter that the investigative reports are true copies of originals on file in their department.
Witness and informant statements should be as brief as possible while containing all essential facts. Whenever possible, signed statements from a minimum of two witnesses should be provided regarding the suspect's actions and/or the facts surrounding the crime.
Witness statements are especially important if there are no documents that establish the suspect's nationality. In such a case, the statement should clearly indicate the witness' knowledge that the suspect is a Mexican citizen. The witness should also provide the suspect's place of birth, if possible.
If witnesses cannot be found to address all of these matters, statements from two investigators that attest to the suspect's citizenship and the victim's identity can be included. An investigator's statement can also include observations of the crime scene as to cause of death and observations of the autopsy as substantiated by the medical examiner's reports.
If the original statement from a witness fails to clearly substantiate the identity of the suspect or the suspect's involvement in the crime, the Mexican prosecutor may require that the witness be produced either in Mexico or, if unable to travel to Mexico, at the nearest Mexican consulate. The Mexican prosecutor or consul may then personally interview the witness. The International Prosecutions Unit will make all necessary arrangements for such an interview if it is required.
Evidentiary Weight of Confessions
Texas law enforcement officials should also note that Mexican law does not allow for a person to be charged with a crime solely upon the basis of his or her confession.
In an Article 4 case where the suspect was first arrested in Texas and later released on bail, the Mexican judges who preside over that person's prosecution in Mexico will make certain that proper procedure was followed while the person was detained in Texas. Although it cannot be used as the sole basis for conviction in Mexico, a confession made by a person who had due access to Mexican consular authorities will carry more weight in a Mexican court.
Consular Notification Under The Vienna Convention
In virtually all circumstances where a foreign national in arrested in the United States, the arresting authority must inform that person that he or she has a right to contact the appropriate consular authorities in the United States. The Office of the Attorney General of Texas has developed the Magistrate's Guide to the Vienna Convention on Consular Notifications, which details procedures that must be followed by local law enforcement under international law when arresting a foreigner in the United States. For a free copy of the guide, please contact the International Prosecutions Unit.
Photographs and Physical Evidence
The case file should include copies of photographs of the crime scene, the autopsy (in case of murder), the victim(s), the evidence, and any other scene or object pertinent to the investigation. All photographs of the evidence, including those of murder weapons, should be accompanied by descriptions on appropriate departmental forms, with signatures of the investigators or criminologists if scientific analyses and examinations were conducted. The same applies to autopsy photographs, which should be accompanied by descriptions signed by the medical examiner. Repetitious photographs need not be included.
It is not usually necessary to introduce physical evidence for a Mexican prosecution; photographs and accurate descriptions on investigative reports will suffice in most instances. At times, the Mexican prosecutor may ask for additional evidence or to view the physical evidence. Again, the International Prosecutions Unit will arrange for the transfer of such evidence if it is required.
Assistance Provided By The International Prosecutions Unit
Successful Article 4 prosecution requires careful preparation, correct authentication of all necessary documents, and timely attention to procedure, as outlined in this chapter. Agencies interested in requesting an Article 4 prosecution should contact the International Prosecutions Unit of the Office of the Attorney General of Texas at (512) 463-2170 for assistance.
In preparation for an Article 4 prosecution, the prosecuting attorney shall:
The International Prosecutions Unit will then:
The Prosecuting Attorney's Review
The requesting agency, if other than the prosecuting attorney, must submit its evidence to the prosecuting attorney's office that has jurisdiction over the case. The prosecuting will attorney then evaluate the case to determine whether there is sufficient legal evidence to warrant prosecution in a Texas court. A Mexican prosecutor, like his United States counterpart, must present sufficient evidence before a Mexican court of law to sustain a conviction. A Mexican prosecutor will not file a case if there is insufficient evidence to warrant an arrest and subsequent prosecution. Despite the procedural and substantive legal differences in our two countries, it is likely that the Mexican prosecutor will find sufficient evidence to warrant a prosecution only if his Texan counterpart believes the evidence would warrant a prosecution in the United States.
Once the prosecuting attorney has reviewed a case file and determined that there is sufficient evidence to warrant a prosecution, he or she should prepare an affidavit to authenticate relevant Texas statutes, as explained in Chapter II. This affidavit should also attest to the authenticity of all other documents in the case file.
The prosecuting attorney's office, as well as the investigating agency, should remember that Article 4 prosecution is voluntary on the part of Mexican officials. The system should not be abused or over burdened. Prospective cases should be closely scrutinized. It bears repeating that prosecutors should not submit cases for prosecution in Mexico that would not meet the sufficiency-of-evidence standard in Texas courts.
Translation of the Case File into Spanish
The requesting Texas prosecutor must prepare two versions of the case file: one in English and one in Spanish. The Spanish translation must be notarized by the translator and legalized along with the original case file by Apostille. Care should be taken to ensure that only the most qualified individuals are solicited to execute necessary translations.
The conviction and punishment of the suspect depend almost exclusively on the contents of the case file. Before it is submitted to Mexican authorities, the file should be checked for accuracy and detail several times over, and the translation should reflect the meticulousness of the original. A poor translation of the case file could result in delays and would undoubtedly cause an added, undue burden upon Mexican prosecutors. It is therefore imperative that the translation be assigned to a reputable professional and thoroughly proofread by another.
It is also advisable that a contract be signed with the translator or agency, most of whom will provide one upon request. The contract should outline fees, payment schedules, deadlines, and clauses of confidentiality.
The Office of the Attorney General of Texas's International Prosecutions Unit will do a final proofreading of the translation. The Unit is also available to provide referrals to reputable, reasonably priced translators throughout the state.
The Unit has bilingual staff who are experienced with reviewing an entire case file and its corresponding translation. Currently, prosecuting attorneys must cover all costs associated with the preparation of the case file, including translation costs.
Legalization of the Case File
On October 5, 1961, via the Hague Convention, the requirement of diplomatic or consular legalization for foreign public documents was abolished. Previously, public documents executed in the territory of one contracting State and which had to be produced in the territory of another contracting State, had to be submitted to the consulate nearest to where the crime was committed. There the Consul General would stamp said documents with his Consular seal to formally legalize said documents.
Today, all that is required is a certificate known as an Apostille, which can obtained from the Secretary of State's Office. The Apostille is issued at the request of the person who has signed the document or of any bearer. [See Fig. III-1: Sample letter requesting Apostille from Secretary of State.]
When properly completed, the Apostille certifies the authenticity of the signature, the capacity in which the person signing the document has acted, and, where appropriate, the identity of the seal or stamp that the document bears.
The signature, seal, and stamp on the Apostille are exempt from all certification. [See Fig. III-2: Model of Apostille certificate.]
Submission of the Case File to the Mexican Authorities
The International Prosecutions Unit will present the case file to the Mexican Federal Attorney General's Office, describing the crime and its prescribed penalty in Texas and specifying the name(s) of the suspect(s).

The Mexican Criminal Justice System
In order to fully appreciate the importance of the Article 4 case file, the Texas prosecutor must envision the trial as it occurs in Mexico: without a jury, without live testimony, and without cross-examination of witnesses by attorneys. The following are highlights of the major phases in a Mexican criminal investigation and prosecution. [See Fig. IV-1: The Mexican Criminal Trial].
The Preliminary Investigation
When the Mexican Public Ministry (Ministerio Público--The Mexican Federal Attorney General is a division of the Public Ministry) receives a written notice requesting an Article 4 prosecution, it directs the federal police to undertake an investigation. This initial phase of a criminal prosecution in Mexico is commonly referred to as the "averiguaciones previas," or preliminary investigation. In Article 4 cases, the investigation consists primarily of a review of the evidence in the case file. On the basis of this investigation, the Ministry makes a formal decision regarding charges.
If no criminal act appears to have taken place, the officials close the case at that point. This is not a dismissal, however, and the case may be re-opened should additional evidence be provided. If the case lacks sufficient evidence for formal charges to be filed but is deemed to have merit, it is placed on hold by authorities until the necessary information and/or proof are gathered.
If the case is considered to have merit and all necessary documentation has been gathered, it is then forwarded to the presiding judge, who issues an arrest warrant. Once apprehended, the suspect is detained for 72 hours while the judge reviews the evidence contained in the case file. If the evidence is deemed to be insufficient, the case is dismissed. If the evidence is deemed sufficient, the judge issues a detention order, "auto de formal prison," by which the suspect is imprisoned to await trial.
If the case fails at any point in this process and the suspect returns to the United States and is apprehended by Texas authorities, he or she may still be prosecuted in Texas. Once Mexican authorities approve and accept a case file and have apprehended the suspect, however, prosecution rests fully in the hands of Mexican courts.
Period of Instruction
The first phase prior to the Mexican trial is the "period of instruction." During this phase, the prosecutor may present additional evidence and the defense is allowed to present its case. This phase is handled completely by way of written documents. For the purposes of Article 4 prosecution, all necessary documentation and evidence should already be in the case file.
Cross-examination may take place during the period of instruction. Following that, the attorneys make their formal written conclusions are presented to the judge. The need for this type of cross-examination is relatively rare, since most questions should have been answered in the form of a legalized statement or interview.
Mexico's criminal prosecutions vary significantly from those in the United States in that there are no jury trials. Decisions are made solely by the presiding judges and may be appealed twice thereafter. Trials occur behind closed doors, and statements and lawyers' deliberations before the judges are kept to a minimum. Witnesses seldom appear to testify in person, since judges make their decisions by carefully studying the evidence presented before them, including depositions and formal statements. Under this system, the evidence contained in the Article 4 case file is the major determinant in the outcome of a trial.
In the unlikely event that the judge deems it necessary to hear live testimony, he may subpoena the desired witness to appear before the court, or he may direct that the witness be interviewed further. If such a witness is in the United States, the International Prosecutions Unit will make the necessary arrangements for an interview before Mexican authorities.
The Decision by the Judge
After evidence has been submitted and taken into account by the judge, the defending and prosecuting attorneys formally appear before the judge and present their final arguments. Additional evidence can be presented in this final stage.
At the close of the final arguments, the judge weighs all of the evidence presented and determines guilt or innocence. If he finds the defendant guilty, it is also the judge who issues the sentence. The judge writes his entire decision, fully detailing the evidence that was presented, and explains the reasoning for such decision. Once the written decision is presented, it becomes final as long as all parties are in agreement.
If either of the parties has an objection regarding the judge's conclusions or the legality of the sentence, an appeal is automatically granted. During the appeal, the evidence and the judge's decisions are reviewed. If the decision is sustained following appeal, habeas corpus is available to the defendant as a last resort.
Manner In Which Penalties Are Applied
Texas prosecutors normally decide how to charge a defendant based on the effect their choice will have on issues such as parole, probation, cumulative sentences, complexity of trial presentation, and double jeopardy. However, Mexican prosecutors do not factor in these considerations. Instead, they present all possible charges to the Mexican courts, who in turn decide whether to pursue some or all of the charges. Texas prosecutors likewise need to include all possible offenses in the Article 4 prosecution file.
Even when an offense may appear to be a lesser included offense in Texas, it might be prosecutable in Mexico as a separate offense, which could lead to increased punishment.
A Note On Juvenile Offenders
Prosecutors contemplating Article 4 prosecution in Mexico for an offender under the age of 18 should note two important distinctions between Mexico and Texas. First, Tex. Penal Code § 8.07 sets 17 as the age of criminal responsibility; Mexico sets the age at 18. Second, Mexican juveniles are not necessarily handled by the criminal system.
Although juvenile offenders may in some cases be incarcerated in Mexico, they are less likely to serve a long sentence. Most will serve time in a rehabilitation facility, not a prison. In Mexico, a juvenile offender is more likely to receive psychological and social services up until the age of majority. Moreover, jurisdiction over the juvenile offender typically ceases in Mexico once he or she reaches the age of majority.
Texas prosecutors should consult with the International Prosecutions Unit prior to discounting an Article 4 prosecution of a juvenile, since Mexican prosecutors might grant an exception in the case of an egregious offense.
When a Texas prosecutor opts to pursue a Texas prosecution instead of an Article 4 prosecution, Tex. Code Crim. Pro. Art. 12.04(a) excludes time in which a defendant absents himself from the state. Therefore, when Texas prosecutors certify and indict juvenile offenders or individuals between 17 and 18 years of age, they should exercise due diligence to serve the Texas warrant.
Prosecutors should check with their local sheriff's office warrant division to assure that the sheriff's office exercises due diligence. Furthermore, when entering Texas Crime Information Center (TCIC) warrant information, all aliases and identifying information should be included. This will increase chances for arrest should the offender reenter the United States.
The Future of Article 4 Prosecution
The Office of the Attorney General of Texas has provided this manual as a resource to encourage Texas and other American prosecutors in their efforts to obtain justice for crime victims. The presence of the international boundary should not confer immunity on criminals from any country. Assistance in this matter is available from this agency. Law enforcement officials are encouraged to call the Office of the Attorney General of Texas.
Prosecutors from Texas and other states should continue to seek extradition of United Sates citizens who commit crimes and flee south to escape justice. When Mexican or other foreign nationals offend in the United States and flee to their native country, they too should be brought to justice by the most effective legal means currently available: prosecution under Article 4 of the Mexican Federal Penal Code.
