A long and bitter chapter of Talisman Energy's involvement in Sudan came to a close Monday after the U.S. Supreme Court tossed out an appeal that sought to hold the Calgary-based oil and gas producer responsible for war crimes and genocide in the North African country. The court gave no reasons for rejecting the case, which was brought by the Presbyterian Church of Sudan on behalf of current and former residents of the country who were affected by the ongoing civil war. The decision ends more than a decade of legal wrangling after Talisman entered Sudan in with the purchase of Arakis Energy in 1998 for $275 million…Company officials declined requests for comment.
