The trial at the district court was scheduled to begin at 9:30 am, when the men aged 20 to 37-years-old stand accused of forming a criminal organisation.
As administrators and moderators of Widerstand Radio, or “Resistance Radio,” the group allegedly played music by German and international neo-Nazi bands.
The music was also accompanied by racist commentary and illegal National Socialist sentiments, according to prosecutors.
The group was arrested in November 2010 during raids by Federal Criminal Police (BKA) in the states of Rhineland-Palatinate and North-Rhine Westphalia.
If the defendants are convicted they face up to five years behind bars.
