In a unanimous decision issued on April 17, the US Supreme Court sharply restricted the use of the 1789 Alien Tort Statute for foreign nationals to sue for human rights violations that took place outside the US. The case at issue, Kiobel v. Royal Dutch Petroleum, was brought by 12 Nigerians now living in the US; they charged that Royal Dutch Petroleum (better known as Royal Dutch Shell) and other oil companies with a presence in the US conspired with the Nigerian government to commit human rights violations against Nigerians protesting environmental damage by the companies.

Guatemalan president Otto Pérez Molina was involved in some of the crimes against humanity for which former dictator Gen. Efraín Ríos Montt (1982-83) and his former intelligence, Gen. José Rodríguez, are now on trial in Guatemala City, according to testimony by a prosecution witness at the trial on April 4. The witness, Hugo Reyes, was an army engineer stationed near Nebaj, El Quiché department, in the Ixil Mayan region, during the early 1980s, at a time when the current president was an army major commanding troops in the area. Reyes said Pérez Molina, then known as "Commander Tito" and "Major Tito Arias," was among the officers in charge of soldiers who "coordinated the burning [of homes] and pulling people out so they could execute them."

With some 500 people packed into the courtroom, the trial of former Guatemalan military dictator Gen. Efraín Ríos Montt (1982-83) for genocide and other crimes against humanity began in Guatemala City on March 19. The charges include the deaths of 1,771 indigenous Ixil Mayan civilians in the central department of Quiché as part of the "scorched-earth" policy implemented during Ríos Montt's dictatorship, which was marked by some of the worst atrocities in a 36-year counterinsurgent war that left an estimated 200,000 people dead, mostly indigenous civilians. Ríos Montt's former intelligence chief, Gen. José Rodríguez, is on trial with him. The proceedings are expected to involve some 130 witnesses and 100 experts and to last several months. Ríos Montt, 86, could face a sentence of up to 50 years.

On March 13 a federal magistrate judge in Columbus, Georgia, sentenced Robert Norman "Nashua" Chantal to a six-month prison term for trespassing on the US Army's Fort Benning base during a protest against the Western Hemisphere Institute for Security Cooperation (WHINSEC), formerly the US Army School of the Americas (SOA), on Nov. 18. SOA Watch, an organization that has sponsored protests at the base each November since 1990, opposes the US Army's training of Latin American soldiers, charging that SOA graduates have been among the region's most notorious human rights violators.

Joined by activists from other social movements, hundreds of students from Guatemalan teachers' colleges marched nearly 50 kilometers to Guatemala City from El Tejar in the central department of Chimaltenango starting on March 10 to protest what they called the "arbitrary and anti-democratic form" of an educational "reform" passed last year. Students from local private schools began joining the marchers as they arrived in the capital around 6 AM on March 12. The protesters headed to the National Congress and surrounded it, demanding a dialogue with Education Minister Cynthia del Aguila. The minister initially refused to meet with the students, but at the end of the day Del Aguila held a press conference with Dialogue Commissioner Miguel Barcárcel and student representatives to announce plans for a discussion—although Del Aguila said this didn't necessarily mean the government was backing down from the reform.

Guatemalan civil organizations held a protest in Guatemala City on Jan. 29 as the opening of an international campaign to demand that the government of President Otto Pérez Molina provide land for 769 indigenous campesino families that were expelled from their fields in the Polochic Valley in the northeastern Guatemalan department of Alta Verapaz in March 2011. The campaign—led by Intermón Oxfam, a Spanish group affiliated with the relief organization Oxfam International—is being carried out in Brazil, Colombia, El Salvador, Guatemala, Mexico, Nicaragua, Peru and Spain.

A Guatemalan judge on Jan. 28 ordered former dictator Efrain Rios Montt to stand trial on charges of genocide and crimes against humanity stemming from the killing of more than 1,700 villagers of Mayan ancestry. Judge Miguel Angel Galvez announced that Montt, along with one of his former generals Jose Rodríguez Sánchez, must answer for the alleged crimes committed during Montt's reign as de facto head of state in the early 1980s. Human Rights Watch Americas Director José Miguel Vivanco called the order "a remarkable development in a country where impunity for past atrocities has long been the norm," and welcomed this step toward greater accountability in Guatemala. Montt is the first ex-head of state to be charged with genocide by a Latin American court.

New Age tourists will be flocking to Mexico's Yucatan Penninsula this week for the "end of the Maya calendar" (sic). But Yucatecan Maya elder José Manrique Esquivel protests that he and his followers will be barred from performing ceremonies at the peninsula's ancient Maya sites. "We would like to do these ceremonies in the archaeological sites, but unfortunately they won't let us enter," Esquivel told the AP. "It makes us angry, but that's the way it is... We perform our rituals in patios, in fields, in vacant lots, wherever we can." Francisco de Anda, press director for the government's National Institute of Anthropology and History (INAH), offers two reasons for the ban: "In part it is for visitor safety, and also for preservation of the sites, especially on dates when there are massive numbers of visitors... Many of the groups that want to hold ceremonies bring braziers and want to burn incense, and that simply isn't allowed."
