In 2015, 22 Indigenous Peruvian environmental activists filed a lawsuit against Xstrata at the London High Court for its alleged involvement in violent protests with two deaths against the company's copper mine. They argue that the company provided financial support to the Peruvian police and logistical aid, equipment, and vehicles, encouraging them to use excessive force against the Tintaya mine protesters. Xstrata denies the allegations and stated that “protection [by the Peruvian police] was necessary…”. In October 2017, a hearing on the status of limitation under Peruvian law took place before the English High Court of Justice. In January 2018, the Court dismissed the claims on the grounds that they are time-barred under Peruvian law.
