A U.S. Supreme Court decision could bring about the parole of seven prison inmates convicted of serious crimes when they were juveniles.

The nation’s highest court has ruled that juveniles who commit crimes in which no one was killed may not be sentenced to life in prison without the possibility of parole.

According to the Iowa Department of Corrections, the decision appears to affect seven cases where a juvenile was convicted of first-degree kidnapping. In each of those seven cases, that juvenile was then sentenced to life in prison. Attorney General Tom Miller has issued a statement, saying the convictions themselves would not be affected by the Supreme Court’s decision, but the Legislature and the Parole Board may be forced to consider allowing those prisoners to be eligible for parole.

In Iowa, a life prison sentence means the convict will spend the rest of their life in prison and will never be eligible for parole.
