The Fourth District Court of Appeal on Wednesday denied John Goodman's motion for a rehearing.
Goodman was behind the wheel of a crash that killed 23-year-old Scott Patrick Wilson in 2010. He was convicted initially in 2012 of DUI manslaughter and again in 2014 after a re-trial.
In May, the same court rejected a challenge by Goodman involving the testing of his blood.
Although justices denied the motion for a rehearing, they did grant his June 28 "Motion for Certification of Questions of Great Public Importance."
The court certified the following questions to the Florida Supreme Court:
1) Are the current rules of the Florida Department of Law Enforcement (FDLE) inadequate under state v. Miles, 775 So. 2d 950 (Fla. 2000), for purportedly failing to sufficiently regulate proper blood draw procedures, as well as the homogenization process to "cure" a clotted blood sample?
2) Are the present rules similarly inadequate for failing to specifically regulate the work of analysts in screening blood samples, documenting irregularities and rejecting unfit samples?
