—Request by Defendant

for Essential Facts Whenever the information charges the offense only by referring to the statute which is alleged to have been violated, the prosecuting authority, upon written request of the defendant, shall as of course amend the information by adding or annexing thereto a statement of the essential facts claimed to constitute the offense charged. Such request shall be made not later than ten days after the first pretrial conference unless otherwise directed by the judicial authority for good cause shown. (P.B. 1978-1997, Sec. 625.)
