The Supreme Court stripped Gen. Augusto Pinochet of his immunity from prosecution in connection with $27 million that he and his wife and children are said to have illegally obtained and deposited in overseas accounts. As a result, the 89-year-old former dictator can now be charged with tax fraud, perjury and use of falsified documents, and prosecutors have said they plan to do so. Similar legal rulings in the past that allowed General Pinochet to be accused of murder and human rights abuses were later overturned on the ground that he was not mentally or physically fit to stand trial, and his lawyers have said they will seek the same judgment in this case.
