TOPEKA, Kan. (AP) — A group upset over a Kansas Supreme Court ruling involving two Wichita brothers convicted of killing four people has begun a push to oust four of five justices up for retention in November.

The Topeka Capital-Journal  reports the group Kansans for Justice is urging voters to cast ballots against retaining Lawton Nuss, Marla Luckert, Carol Beier and Dan Biles. The group supports retaining Gov. Sam Brownback’s only selection, Caleb Stegall, who came onto the court after the Carr brothers ruling.

The two men were sentenced to death for the December 2000 shootings of five people at a soccer complex, killing four. The Kansas Supreme Court vacated the death sentences in 2014 after ruling their constitutional rights had been infringed upon, but the U.S. Supreme Court later reversed the decision.
