Jim Mansfield Junior and his younger brother PJ will stand trial in November on ammunition charges.
The sons of the late businessman Jim Mansfield pleaded not guilty during a brief appearance before Dublin District Court this morning.
Jim Mansfield Junior (48) is accused of illegally having 180 rounds of ammunition at his home on Garter Lane in Saggart, south Dublin on January 29th 2015.
His brother PJ Mansfield (38) of Coldwater Lakes - also in Saggart - is accused of possession of over 1,200 rounds without a firearms licence at that address on the same date.
Both men were in court this morning and both asked for hearing dates.
A trial date has been set for November and the Mansfields have been remanded on continuing bail until then.
