Sudan class action disappoints firm - Talisman Energy Inc. is "disappointed" about a class-action lawsuit filed in the United States against the company yesterday alleging complicity in human rights abuses in Sudan, a spokesman for the company said. "Obviously, Talisman believes in and respects human rights of all individuals around the world, so we're disappointed to learn of this action," said David Mann, the company's manager of investor relations. "We believe we have actively promoted transparency, respect for human rights and an end to the civil war in Sudan."
