(AP) — Justices of the Kansas Supreme Court now have four cases related to the state’s “Hard 50” prison sentence to digest in the coming months, with about a dozen others still in the legal pipeline.

While each case has its specific set of circumstances, the justices honed in on other issues about the convictions and sentences, rather than whether changes made to the state’s “Hard 50” law this fall can be applied retroactively like legislators want.

The four cases involve defendants who have been sentenced to life in prison with eligibility for parole after 50 years.

The justices gave no indication how quickly they would rule on the cases. Their decisions could still leave the question of retroactivity unresolved if the facts of the convictions are upheld.
