On 6 October, the U.S. Supreme Court (SCOTUS) rejected an appeal that had been submitted by 10 individuals against the former Mexican president Ernesto Zedillo Ponce de León (1994-2000) for his responsibility in the Acteal massacre (December 1997), which left 45 dead in Chiapas state. SCOTUS did not justify its decision; instead it simply upheld the decision made in February 2013 by a federal judge in Connecticut, holding that Zedillo has political immunity as a former head of state.
The initial demand had been presented in 2011 in Hartford, Connecticut, accusing Ernesto Zedillo of having covered up the events of the massacre. The case was submitted in Connecticut because that is where he resides, being a professor at Yale University. Plaintiffs had demanded compensation of $50 million for relatives of the victims of the massacre.
