The charges against Swiss entrepreneur Stephan Schmidheiny as part of the Eternit asbestos case were on Tuesday changed from manslaughter to involuntary manslaughter...[A] Turin judge ruled that about a hundred of the cases had reached the statute of limitations and ordered that others be transferred to the Reggio Emilia, Vercelli and Naples prosecutor's offices.  Only two cases remain in Naples, for which a trial will begin on June 14...The lawyer, Sergio Bonetto, noted that the transfer of the cases to three other prosecutors' offices would significantly lengthen the time "before the cause of and responsibility for these deaths can be ascertained".
