A lawyer for former Chilean president Gen Augusto Pinochet has called for the judge investigating him to be removed from the case.
Pinochet was president of Chile from 1974 to 1990
The lawyer said the judge, examining accusations of human rights abuses, had shown antagonism towards his client.
The lawyer's comments are effectively a declaration of war against Judge Juan Guzman.
He is due to resume his inquiry after the Supreme Court last week voted to strip Mr Pinochet of legal immunity.
Kidnappings and torture
Chief defence lawyer Pablo Rodriguez said that in the interests of transparency and fairness, the judge should not continue with the case.
He said he was studying the option of a formal court application against the judge.
The lawyer also called for fresh medical tests for the 88-year-old former president.
The defence team has consistently argued that Mr Pinochet is mentally unfit to stand trial.
Judge Guzman is investigating accusations that the general was responsible for kidnappings and torture.
Human rights lawyers dismissed the comments from the defence team as another attempt at subterfuge.
But they demonstrate that the general will be fighting the accusations vigorously and there will be no co-operation with the investigating authorities.
