Prosecutors have asked the Utah Supreme Court to order a lower court to review its reversal of a physician's negligent homicide conviction in the 1986 death of an infant delivered at home.

A 2nd Circuit Court jury convicted Dr. David R. Warden, Layton, of the class A misdemeanor, and he was placed on two years' probation and fined $3,100.In a 2-1 vote, the Utah Court of Appeals last November reversed the conviction, ruling the evidence failed to establish criminal negligence.

Davis County prosecutors contend the doctor was negligent in not immediately hospitalizing the infant that died 11 hours after being delivered Nov. 7, 1986.
