"Under R.C. 2929.19 as it stands without (B)(2), the defendants are entitled to a new sentencing hearing although the parties may stipulate to the sentencing court acting on the record before it. Courts shall consider those portions of the sentencing code that are unaffected by today's decision and impose any sentence within the appropriate felony range. If an offender is sentenced to multiple prison terms, the court is not barred from requiring those terms to be served consecutively. While the defendants may argue for reductions in their sentences, nothing prevents the state from seeking greater penalties. United States v. DiFrancesco (1980), 449 U.S. 117, 134-136, 101 S.Ct. 426, 66 L.Ed.2d 328."
