localization model.It has also carried out diagnostic and monitoring visits in 20 federal entities and conducted planning workshops in six. 473.In the field of international cooperation SETEC has conducted several projects with foreign governments, notably those of Canada and Chile. Each of these projects involved many activities such as planning workshops, discussion forums, international seminars, training courses for judges, defenders, prosecutors and lawyers, and technical advice on specific aspects of reforming the criminal justice system. We have also developed important ties with other foreign governments, enabling us to undertake learning missions to Colombia and Costa Rica, while other cooperation programmes with various international bodies are impending. 474.At the same time, SETEC devised the national training programme to provide approved nationwide guidelines, setting quality and performance standards. It has also given many training courses for operational staff of the justice system throughout the country. It has developed framework curricula for training operators and for undergraduate and graduate studies in educational institutions, and formed a training committee to achieve high levels of quality by including a methodology for validating study plans and programmes and for recruiting trainers and teachers after a specialized certification process. 475.In the field of technical assistance, a programme entitled Reorganization of the Criminal Justice System in Mexico was prepared as a guide for existing institutions in their new role and activities, as well as those that need to be set up for an adversarial system. There is an architectural model and guide for designing and planning courtrooms for oral hearings and related services, and draft general criteria for information and communication technology. 476.From 2004 to date, 8 of the 32 federal entities have made amendments to their legislation and begun implementing the new adversarial criminal justice system in Mexico, namely: Baja California, Chihuahua, Durango, Mexico State, Morelos, Nuevo León, Oaxaca, and Zacatecas; 4 have already introduced legislative reforms and began implementation in 2011: Guanajuato, Hidalgo, Yucatán and Puebla; 13 federal entities are at the planning stage: Campeche, Chiapas, Colima, the Federal District, Guerrero, Jalisco, Michoacán, Queretaro, San Luis Potosí, Sonora, Tabasco, Tamaulipas and Tlaxcala, while 7 federal entities are at the initial stage of implementation, and are beginning to make progress with the planning process and some isolated institutional efforts: Aguascalientes, Baja California Sur, Coahuila, Nayarit, Quintana Roo, Sinaloa and Veracruz. 477.The second transitional provision of the constitutional reform left open the possibility of defining how gradually the reform should be introduced, whether by region or by type of offence. Most states have chosen the regional option, which has allowed them to detect any faults and make practical improvements as other regions progress with implementation. 478.We set out below the main reforms achieved in the federal entities at the operational stage: Baja California 479.Baja California already has legislation that has introduced the new system of criminal justice. The Code of Criminal Procedure entered force on 11 August 2010 in the municipality of Mexicali. Implementation will be gradual, starting with the municipality of Mexicali, followed by Ensenada (August 2011), culminating in Tijuana, Playas de Rosarito and Tecate (August 2012). 480.The state has made significant progress on infrastructure, training, technological systems, the process of selecting legal operators and social communication. Its substantive organizational legislation is already complete. Chihuahua 481.Chihuahua was the first state to embark on the comprehensive reform process. The new criminal justice system is now applicable throughout the entire state, but implementation began on 1 January 2007 when it entered force in the Judicial District of Morelos (which includes the municipality of Chihuahua); a year later the new system was applied in Bravos Judicial District (which includes the municipality of Ciudad Juarez); and finally on 1 July 2008 in the rest of the 12 judicial districts. They decided to start in those municipalities since they had more trained staff. 482.This state approved the complete legislative package including organizational and substantive regulations. Substantial progress has also been made in training, outreach, infrastructure and equipment. Durango 483.In Durango, the new Criminal Justice System came into force on 14 December 2009 in the district with the largest number of lawsuits and the main town of Durango, which includes the municipalities of Durango, Mezquital and part of San Dimas. It will be implemented next in the district with the main town of Gomez Palacio, and the rest gradually. The first trial by oral proceedings was held in the state on 19 April 2010. 484.In the case of Durango, it was also decided to enact a comprehensive legislative package that includes the substantive and organizational law. Significant progress has been made in dissemination, reorganization, discharge and infrastructure. State of Mexico 485.In 2009 the state of Mexico began to implement the new criminal justice system and strengthen legal and institutional aspects of the administration of justice. 486.The oral adversarial criminal procedure introduced by the new Code of Criminal Procedure of the State of Mexico, in force since October 2009, is based on human rights principles enshrined in the Mexican Constitution and international treaties:
