The appeals process for Castelli and the other two was separated for technical reasons. The appellate court's reasoning was expected to be released in 15 days, but defense lawyer Alessia Sorgato said the decision noted extenuating circumstances.
"That goes some way to saying they acted on orders of a superior," said Sorgato, who represents Medero. She said she was satisfied that the sentences were less than that for the other Americans. She will decide whether to appeal to the highest court after reading the court's reasoning.
Meanwhile, another appeals trial in the case opened last week in Milan --that of the five Italians acquitted for state secrets. A conviction of the Italians would hold consequences for U.S.-Italian relations by potentially demonstrating official Italian involvement in the case.
