Imed Trabelsi, nephew of the former president’s wife, already received a four year prison sentence for drug use and possession.
Five other cases against him have been adjourned until Nov. 25.
Officials have said Trabelsi will stand trial on other charges including corruption and illegal trafficking of archaeological items.
President Zine Abidine El Ben Ali fled to Saudi Arabia Jan. 14 amid a public uprising. He and his wife, Leila Trabelsi, have been convicted in absentia Monday and sentenced to dozens of years each in prison and fined millions of dollars.
