Eleven people appeared in the Musina Magistrate's Court on Tuesday for allegedly dehorning rhinos and selling the horns without a permit, the National Prosecuting Authority said.
"The matter was postponed to October 19 to give the defence time to finalise their application on further particulars on the charges," NPA spokesman Mthunzi Mhaga said.
Game farm owner Dawie Groenewald was among the accused.
He and the 10 others were implicated in the dehorning of rhinos and selling the horns internationally without permits.
Groenewald, 42, owns the farm Prachtig, outside Musina.
He was arrested in September 2010 along with several other people --including his wife and two veterinarians -- on charges related to rhino poaching.
