A man sentenced to life in prison under Colorado’s habitual-offender law for twice robbing an ice cream store cannot seek to have his sentence reduced in the wake of a 2019 Colorado Supreme Court ruling, the justices decided in a pair of cases Monday. The unanimous opinions close the door for people serving decades in prison on habitual-offender sentences who had hoped to challenge their prison terms after the state Supreme Court issued a ruling in 2019 that changed the proportionality review process for such sentences. The justices ruled Monday that the 2019 opinion does not apply retroactively to prior convictions. The new ruling sprang from two underlying cases in which Black men were sentenced to decades in prison under Colorado’s habitual-offender law, which imposes drastically longer prison sentences for defendants who have previously been convicted of two or three prior felonies. David Ward, 62, was sentenced in 1993 to life in prison with the possibility of parole after 40 years for twice robbing the same Denver Dolly Madison ice cream store a few days apart in December 1991.
