Legislation revamping a Kansas law imposing an automatic 50-year sentence on some convicted murderers is now in the state Senate.

The House passed the measure 122-0 Tuesday on the first day of a special session prompted by a U.S. Supreme Court decision that struck down a similar law in Virginia.

The Senate Judiciary Committee was scheduled to begin reviewing the House-passed measure Wednesday. It differs slightly from a version discussed last week by a special legislative committee charged with reviewing the issue.

Kansas adopted the so-called Hard 50 prison sentence in 1990, when the Legislature rejected the death penalty but wanted to ensure long sentences in certain murder cases.
