Rock star's son Otis Ferry has denied attacking a hunt monitor and robbing another while they were trying to film him at his sport.
Countryside campaigner Ferry, 25, of Eaton Mascot, Shropshire, Ferry appeared at Gloucester Crown Court to answer charges of robbery and common assault.
Dressed in a dark grey striped suit, Ferry, who previously gave his full name as Charles Frederick Otis Ferry, denied robbing Susan Grima of a Samsung video camera on November 21 last year at Lower Swell, near Cheltenham.
The son of Roxy Music singer Bryan Ferry also pleaded not guilty to assaulting Helen Ghalmi by beating on the same date.
The incident is alleged to have taken place while Ferry was with the Heythrop Hunt, which covers Oxfordshire and Gloucestershire.
Ferry's counsel Paul Lucas previously told the court his client's defence case would be one of mistaken identity.
Judge William Hart told Ferry he will now stand trial at Gloucester Crown Court, sitting in Cirencester, Gloucestershire, on September 15. It is likely to last four days.
