Defense lawyers demanded Monday that kidnapping charges against Winnie Mandela be dropped because prosecutors failed to provide enough details to back up their case.

State prosecutors asked for and were given until Tuesday to react to defense requests to quash various assault and kidnap charges against Mrs. Mandela and three co-defendants. Defense lawyers charged the state failed to meet its legal obligation to detail the charges.Mrs. Mandela emerged smiling from the courtroom with her husband, African National Congress leader Nelson Mandela, as supporters cheered and chanted her name. A beaming Mrs. Mandela shot her clenched fist into the air as she and her husband were mobbed by admirers.

State prosecutors allege four youths were taken to Mrs. Mandela's home and beaten in December 1988. The youngest youth, 14-year-old Stompei Seipei, was killed.

The youths were abducted because they were accused of having sexual relations with a white Methodist minister and Seipei was suspected of being a police spy, according to prosecution charges.

Jerry Richardson, head of Mrs. Mandela's disbanded bodyguard, the Mandela United Football Club, was convicted of murder in the case and is appealing a death sentence. A judge has ruled Mrs. Mandela was present during the assault.

Mrs. Mandela has said she is innocent. Dressed in a yellow and blue plaid jacket and dark skirt Monday, she appeared relaxed and confident as she sat in the courtroom.

Four former Mandela bodyguards who were co-defendants failed to appear for the trial Monday and warrents were issued for their arrest. Appearing with Mrs. Mandela were three other defendants - Johan Morgan, Xoliswa Felati and her daughter, Mompumelelo Felati.
