The Idaho Supreme Court has denied requests from six death row inmates who said they were entitled to new trials because a U.S. Supreme Court ruling made after their convictions called on juries, not judges, to impose the death penalty.

All the men argued that the state violated their Sixth Amendment due process rights because they were sentenced to death by a judge instead of a jury, as required under the 2002 federal decision.

But in a unanimous ruling handed down Friday, the Idaho Supreme Court noted that their cases were all appealed and the judgments made final before the U.S. Supreme Court ruling was issued — and that 2002 decision can't be retroactively applied to the Idaho inmates' cases.

All six inmates have appeals in various stages of state and federal court that will now move forward.
