The trial has already been substantially delayed due to Chiluba's poor health.
Chiluba has a heart condition. Emmanuel Mwamba, his spokesman, said: "Chiluba decided to come to court despite his illness than to allow a video link installed at his house."
The judge had ordered that Chiluba be tried through a video-link connection in his house if his heart condition remained acute, preventing him from appearing in court.
But Mwamba said that Chiluba objected to the video-link.
He said: "A video-link trial is illegal and Chiluba will not promote illegality."
Chiluba has denied the corruption charges and blamed his hand-picked successor Levy Mwanawasa, now president, of trying to destroy his legacy and reputation.
