U.S. case against Ye Gon
In 2007, Zhenli Ye Gon was indicted in the
United States District Court for the District of Columbia with a single count of conspiracy to aid and abet the manufacture of 500 grams or more of
methamphetamine, knowing or intending that it would be imported into the United States. Federal agents arrested him in a
Wheaton, Maryland restaurant on July 23, 2007. From the date of his arrest, Ye Gon has always maintained that he is not guilty. Prior to the Mexican government's enforcement actions, Ye Gon was openly building a state-of-the-art pharmaceutical plant in
Toluca, Mexico, and in his federal court proceedings, the U.S. prosecutor referred to Ye Gon as "a very sophisticated businessman." Although the criminal allegations arose from Unimed's importation of four shipments of alleged
precursors of pseudoephedrine and ephedrine during 2005–06, Unimed still had on-hand, in March 2006, an unsold balance of 9.806 metric tons of finished pseudoephedrine products, which had been legally imported in 2004, but which were still sitting in its warehouse. With the consent of Mexican officials, this large quantity of pseudoephedrine products was sold in compliance with the Mexican government's directions. During his U.S. proceedings, Ye Gon's lawyers pointed out the incongruity of Unimed allegedly importing unfinished pseudoephedrine products while it still had on hand almost 10 metric tons of finished pseudoephedrine products, which had been sitting idly for years, and could have been diverted if criminal activity had been contemplated. They also noted how none of the four challenged shipments were listed as containing pseudoephedrine or ephedrine precursors, and that Mexico's government-approved chemist assigned to Unimed, Bernardo Mercado Jiminez, stated under oath that he did not know that the imported substances were prohibited under Mexican law, and that he advised Ye Gon, who is not a chemist, that the imported substances were legal chemicals not controlled or restricted under Mexican law. Samples taken from the four challenged shipments by Mexican officials were never turned over to U.S. authorities for independent testing, as Ye Gon's U.S. defense counsel had requested. The U.S. prosecutor reported that "the [U.S.] government was told that the samples from the first two intermediate shipments sampled had been used up in the laboratory analysis." The fourth shipment had been seized by Mexican officials in its entirety, but its contents too apparently have now been destroyed. Questions have also been raised by Ye Gon's defense experts about the methodology of the earlier testing of these samples conducted in Mexico's laboratories. During Ye Gon's U.S. prosecution, the lead U.S. prosecutor also openly admitted that "I am not proffering that I have interviewed a witness, you know, who is a drug trafficker who said I got ephedrine or pseudoephedrine from him, so that to me would be a smoking gun kind of witness.... I don't want the Court to think that's what I'm saying because I'm not saying that. What I'm saying is that there's other kinds of testimony." Ye Gon was scheduled to go to trial on his U.S. charge in September 2009. On June 22, 2009, the U.S. Department of Justice filed a motion to dismiss its case against Ye Gon, citing Mexico's interests as well as evidential concerns. At a hearing on the same day, prosecutors admitted that one of their key witnesses had recanted. and
A. Eduardo Balarezo vigorously litigated this
Brady issue before the Honorable
Emmet G. Sullivan. As a result of the efforts of Messrs. Retureta and Balarezo, all charges brought against Ye Gon by the government of the United States were
dismissed with prejudice on August 28, 2009. Judge Sullivan also noted how "this court made numerous inquiries of government counsel as to just what the status of the requests were to get drug samples for testing purposes, to provide evidence for the prosecution, and basically ... Mexico just snubbed the United States." Mexico's separate pending criminal charges against Ye Gon were not dismissed, however, and the U.S. Department of Justice continued its efforts to extradite Ye Gon to Mexico to face criminal charges there. Renewed efforts by Ye Gon's lawyers to have him released on bail following the dismissal of his U.S. criminal case proved unsuccessful, and a U.S. magistrate judge ordered that Ye Gon must remain in custody pending a decision on whether the U.S. can extradite him to Mexico to face charges there. In March 2010, Ye Gon retained the services of lawyer Gregory S. Smith to represent him in his extradition case before the United States District Court for the District of Columbia. On February 9, 2011, Magistrate Judge John M. Facciola certified Ye Gon's extraditability to Mexico to face charges there. In his habeas petition, Ye Gon has argued that in light of the U.S. case's dismissal, his extradition is barred by principles of
international double jeopardy (
non bis in idem). In light of Government admissions that "Mexico has not set out to prove ... That Ye Gon mass produced methamphetamine itself," Ye Gon has also claimed that extradition is improper under the legal requirement of dual criminality (since the alleged precursor chemicals imported into Mexico are not controlled substances in the U.S.), and other barriers. The petition also notes how many of Mexico's allegations of wrongdoing underlying the extradition request come from statements made by disgruntled and/or fired former employees of Unimed, and that the Mexican arrest warrant's listed "main accomplice" of Ye Gon has since recanted. In addition, the key Mexican prosecutors responsible for Mexico's charges against Ye Gon have themselves since left office. Jorge Joaqin Diaz Lopez, the lead prosecutor who swore out and presented Ye Gon's Mexican arrest warrant, submitted a "voluntary irrevocable resignation" in January 2009, following a Mexican anti-corruption initiative known as Operacion Limpieza ("Operation Clean-Up), although Mexico continues to claim that Diaz resigned for personal reasons. Diaz's boss at the time, Noe Ramirez Mandujano - who served as the head of Mexico's national organized crime unit - was himself later criminally charged and jailed in November 2008, after allegedly receiving $500,000 in exchange for providing sensitive information to drug cartels in Mexico. Zhenli Ye Gon was extradited to Mexico in October 2016. ==Mexican case==
