Florida has asked the state's high court to reject a condemned inmate's request to delay his execution based on the U.S. Supreme Court's finding that Florida's procedure for imposing the death penalty is illegal.

In a brief filed Thursday, Florida Attorney General Pam Bondi's office said the U.S. Supreme Court's finding should not be applied retroactively to already-settled death penalty cases.

Ruling on the Hurst v. Florida case Tuesday, the nation's highest court ruled 8-1 that Florida's procedure is flawed because it allows judges, not juries, to decide death sentences.

Attorneys for convicted killer Michael Lambrix cited the ruling in their request for a new sentencing hearing for him.

Lambrix is scheduled to be executed by lethal injection on Feb. 11.

It wasn't clear when the court would rule.
