According to media sources, the government of Mexico, by means of the Secretariat of Foreign Relations (SRE), sent a diplomatic note to the U.S. State Department in November of last year that requests that ex-president Ernesto Zedillo (1994-2000) be granted immunity, given that he has since 19 September 2010 confronted a legal case presented in the U.S. by a dozen relatives of victims of the Acteal massacre that took place in Chiapas in 1997.\
On 6 January, Zedillo himself presented a petition to the U.S. court in Connecticut and denied responsibility for the case.
Civil-society organizations and legislators have questioned both actions. Deputies Sofia Castro (PRI) and Mauricio Toledo (PRD) have claimed that immunity should not be confused with impunity; for this reason the ex-president should be treated like any other Mexican citizen. For her part, Zoila Luna, coordinator of the Méndez Arceo Foundation, has indicated that the petition for immunity formulated by the SRE is yet another demonstration of the commitment of the Mexican State to human rights. She made this comment after presenting the call for the 20th iteration of the Sergio Méndez Arceo National Prize for Human Rights.
