In a divided ruling, justices strike down portions of federal guidelines, forcing a redrawing of the sentencing system.
The US Supreme Court has set the stage for a historic transformation of the criminal justice system in a ruling that requires federal judges to find a new way to mete out punishments to convicted criminals.
The nation's highest court Wednesday struck down a portion of the federal sentencing guidelines system designed to help judges hand down similar punishments for similar crimes - a system that has been in operation in federal courthouses for 17 years.
At the same time, however, a majority of justices upheld the basic structure of the guidelines system. The move may help reduce the level of confusion as federal courts attempt to apply the Supreme Court's decision to the estimated 80,000 criminal defendants sentenced each year within the federal court system.
Much of the federal sentencing system had slowed to a near halt since last June when the high court issued a ruling raising serious questions about the viability of the sentencing guidelines. Legal analysts say the decision has lived up to expectations.
"This is one of the most important decisions involving practical effects in the criminal system in United States history," says Marc Miller, a sentencing expert at Emory Law School. "It ranks up there with Miranda."
In effect, the high court issued two decisions in one, with each ruling reflecting the views of different factions of justices.
By a 5-to-4 vote, the justices said the application of the guidelines violated the Sixth Amendment right to a jury trial. This group of justices, led by Justice John Paul Stevens, said the guidelines impermissibly allowed judges in some instances to become a jury of one by handing down sentences that exceeded the prison term authorized by a jury's verdict at trial.
A second group of justices, led by Justice Stephen Breyer, ruled 5 to 4 that the guidelines system could be largely salvaged from the constitutional problems identified by the other justices by severing the portion of the federal sentencing statute that makes the guidelines mandatory. By striking the mandatory requirement, the guidelines would become merely advisory, thus permitting judges to tailor particular sentences in light of other legally authorized concerns.
