The Supreme Court of Canada on Sept. 4 ruled in favor of Ecuadoran villagers seeking to enforce a multi-billion dollar judgment against the Chevron Corporation. In 2011, the 30,000 villagers secured the $17.2 billion judgment in an Ecuador court for environmental damage to rainforest in the Lago Agrio region. Damages were subsequently reduced by an appeals court to $9.5 billion. The new 7-0 ruling means that the Ecuadorans may pursue the judgment against Chevron in Canada through its subsidiary, Chevron Canada Ltd. Chevron has put up a vigorous legal battle to avoid the fine, arguing that, because the damage was perpetrated by Texaco between 1972 and 1990, before it was bought out by Chevron in 2001, and because Texaco signed an agreement with Ecuador to absolve it of responsibility after a $40 million cleanup effort, Chevron should not be required to pay out for its former competitor.

The Extraordinary African Chambers on Sept. 3 confirmed that war crime accusations have been filed against Chad's President Idriss Deby. The special tribunal in Senegal is overseeing the case against the former president of Chad, Hissène Habré (BBC profile), who was accused of crimes against humanity, war crimes and torture. A Senegalese lawyer, Mbaye Jacques Ndiaye, filed the charges against Deby to hold him responsible for the role he played in perpetuating the alleged crimes of his predecessor while he served as Habré's army chief.

Syrian civilians are facing war crimes and crimes against humanity with "no end in sight," a group of UN human rights experts finds. The Independent International Commission of Inquiry on the Syrian Arab Republic issued its latest report (PDF) on the civil war in Syria Sept. 3. Paulo Sergio Pinheiro, chair of the UN investigative panel, stated to members of the Associated Press that the Islamic State (IS) seems  to be "desperate, because they are losing ground." According to the report, IS suffered significant losses to the Kurdish armed group, the People's Protection Units (YPG), and has resorted to using suicide car-bombs and hit-and-run tactics. US intelligence agencies seem to disagree with Pinheiro, as the CIA and other agencies announced in July that their assessments show IS is "fundamentally no weaker than it was when the US-led bombing campaign began a year ago."

Guatemalan President Otto Pérez Molina sent a letter to both the country's congress and reporters early Aug. 3 announcing his resignation and his intention to "stand before justice." The congress had called an emergency session to meet that day to accept the letter of resignation. Several hours before resigning, the public prosecutor requested Pérez Molina's arrest on corruption charges and a trial judge ordered his arrest. Pérez Molina and 30 other government officials allegedly took millions of dollars in bribes in exchange for keeping low import duties. Vice President Alejandro Maldonado has assumed the presidency, and must compile a list of three names for consideration for vice president, to be chosen by congress. Maldonado replaced vice president Roxana Baldetti, who was arrested in August on corruption charges. Eight other government officials have already resigned over the allegations. Pérez Molina's resignation comes only three days before the Guatemalan general election.

The trial of Bosco Ntaganda (BBC profile), a former Congolese rebel leader also known as "The Terminator," began at the International Criminal Court (ICC) Sept. 2. The rebel leader has pleaded innocent to the 18 charges levied against him, including rape, murder, recruitment of child soldiers and sexual slavery of civilians. He has been accused of killing at least 800 civilians between the years of 2002 and 2003 and keeping girl soldiers as sex slaves. The trial is expected to last for a few months with the anticipation that approximately 80 witness will be called. He faces a maximum life sentence if convicted.

Chinese authorities arrested 12 individuals Aug. 27 for illegally storing dangerous materials that led to the Tianjin warehouse explosions, which killed at least 139. Those arrested include Yu Xuewei, chairman of Tianjin International Ruihai Logistics Co Ltd, and Zeng Fanqiang, an employee with a safety firm. The Chinese Ministry of Public Security alleged that the safety firm illegally allowed warehouse owner Tianjin Ruihai to pass safety evaluations and obtain hazardous materials without actually meeting the safety requirements. Eleven other officials are under investigation for alleged neglect of duty and abuse of power relating to the explosion of 700 tons of sodium cyanide and other chemicals.

A Guatemalan court on Aug. 26 held that former dictator Efraín Ríos Montt can stand trial for genocide and crimes against humanity but cannot be sentenced because he suffers from dementia. The court held that a special closed trial can be held where all evidence and witness testimony will be presented with representative of Ríos Montt present. Ríos Montt's lawyers have an opportunity to appeal. This ruling comes after a Guatemalan court, earlier this month, ordered Rios Montt to undergo competency tests to determine whether he was fit to stand trial. In May the Guatemalan Congress approved a resolution denying any existence of genocide during the country's civil war.

An independent UN human rights expert on Aug. 21 commended Mauritania for adopting a new law that establishes harsher sentences for slavery crimes, urging full implementation. The law adopted last week by the Mauritanian National Assembly doubles prison terms for slavery convictions, declared slavery a crime against humanity, and created tribunals to handle slavery prosecution cases. UN Special Rapporteur Urmila Bhoola said that the law is an important step on a road map toward eradicating slavery but insisted that "slavery and slavery-like practices can be eradicated only if the existing laws, policies and programs are implemented fully and effectively. This statement comes just one day after a court in Mauritania upheld  a two-year prison sentence for Biram Dah Abeid, an anti-slavery activist convicted of inciting trouble and belonging to an unrecognized organization.
