The trial was delayed until January 21 by a panel of judges following the absense of the athletes.
The two sprinters were accused of missing a doping test and staging a motorcycle accident to avoid being tested on the night of the 2004 opening ceremony.
Kenderis, who won a gold medal in the 200 metres at the Sydney 2000 Olympics and Thanou, a silver Olympic medallist in the 100 metres, were Greece's biggest medal hopes for the Athens Games. They both face misdemeanor charges of perjury over the motorcycle accident, along with 10 other people including their coach, doctors and alleged witnesses of the accident.
The Greek Athletics Federation (SEGAS) cleared both athletes of doping charges but they were suspended for two years by the International Amateur Athletics Federation (IAAF). Thanou returned to international competition in 2007 but was barred from taking part in the 2008 Beijing Olympics.
