Former state Sen. Vincent J. Fumo must be resentenced, the 3rd U.S. Circuit Court of Appeals has ruled, because the trial judge made a series of errors in the sentencing process and failed to explain precisely how he decided to reduce the recommended prison term under the guidelines to 55 months.

Voting 2-1, the court found that Senior U.S. District Judge Ronald L. Buckwalter miscalculated the losses caused by Fumo’s massive fraud schemes in several ways and also failed to impose two key “enhancements” that would have increased the recommended sentence.
