Lyle Howe is one of two people charged with sexual assault and administering a noxious substance to a woman more than nine months ago.
Donald McLeod, a Toronto-based lawyer, appeared on Howe's behalf today at Halifax provincial court to set a date for the inquiry, which is slated for May 30 and 31.
The 27-year-old Howe previously elected a trial by judge and jury for the alleged March 21, 2011, incident involving a 20-year-old woman.
Howe was hired by Nova Scotia politician Trevor Zinck to fight fraud and theft charges stemming from the province's spending scandal.
Twenty-eight-year-old Jeffrey Kendall Brown also elected to be tried by a judge and jury.
His preliminary inquiry is scheduled for June 1.
