Doctors restricted the time Demjanjuk could be tried in court each day to two sessions of 90 minutes each, according to Munich State Prosecutor Anton Winkler. On 30 November 2009, Demjanjuk's trial, expected to last for several months, began in Munich. Demjanjuk arrived in the courtroom in a wheelchair pushed by a German police officer. Because of the long pauses between trial dates and cancellations caused by the alleged health problems of the defendant and his defense attorney Busch's use of many legal motions, the trial eventually stretched to eighteen months.
