Kansas Attorney General Derek Schmidt says he’s working with local prosecutors to draft a consensus proposal for repairing a state law that allows convicted murderers to be sentenced to at least 50 years in prison.

Schmidt watched Tuesday as Gov. Sam Brownback signed a proclamation calling the Legislature into special session Sept. 3 to rewrite the “Hard 50” law.

The attorney general asked for the special session because of a U.S. Supreme Court decision in June raising questions about the law’s constitutionality. Schmidt’s request had bipartisan support from prosecutors.

Schmidt said the measure he’ll propose will ensure that the “Hard 50” still can be imposed going forward. But he said it will also seek to apply any changes to pending first-degree murder cases.
