George Proctor, an 86-year-old consultant botanist at the University of the West Indies, is to be tried in the Home Circuit Court on December 4.
He is charged jointly with his driver Glenford Pellington with conspiracy to murder.
The Crown is alleging that Proctor allegedly paid Pellington $90,000 to murder his 66-year-old wife.
