The independent member of Parliament has been on a hunger strike for 35 days after he was remanded in custody on suspicion of involvement in war crimes against civilians in the eastern city of Osijek in 1991.
Madunic told Hina this morning he had been contacted by doctors from the prison hospital saying they would not let the patient go to court today regardless of his wish to attend the hearing.
The lawyer added that he would not be attending the court hearing either, and that he would ask Zagreb County Court investigating judge Zdenko Posavec to temporarily suspend the proceedings.
Glavas's defence team announced on Thursday they would request that witness hearings at which Glavas wished to be present should be held in the prison hospital in case their client was no longer fit to go to court.
However, Zagreb County Court spokesman Kresimir Devcic said that this would not be possible as all proceedings had to be conducted in the court building, especially cases at an investigation stage like Glavas's.
