The decision was actually 1996. I found this:

"Though the full implications of the decision are not clear, a Justice Department spokesman in Washington said "there's concern" about the effect on future cooperation between the United States and Italy in the war against organized crime. In the past, both countries have worked closely and the 1983 treaty has been invoked to help extradite mob figures for trial in the United States.
The spokesman, John Russell, said of the court decision today, "I think it serves as a bad omen.""
Also:
Last December, Rome's Justice Ministry agreed to Mr. Venezia's extradition after the Dade County prosecutor's office made assurances that it would not seek the death penalty.
"Mary Cagle, the Dade County prosecutor who sought Mr. Venezia's extradition and had agreed to forgo the death penalty, said, "I just don't think there's any justice there."
In at least several instances, Mr. Russell said, the United States has given assurances to Canada about forgoing the death penalty.
But Giovanni Leone, a former President of Italy who had taken up Mr. Venezia's cause, described the decision as "one of historic character that does honor to Italy.""
And:
"Italian officials pointed out that the penal code requires that Mr. Venezia be tried by an Italian court. But American officials were not satisfied. Mr. Russell, the Justice Department spokesman, said, "That falls short of what we want.""
The facts of the case are quite plain. It is a little disingenuous of the pro guilt mob to seek to lecture the United States in the Kercher case with regard to its obligations in matters of Italy/USA cooperation.
