On December 1, 1983, Pisani was indicted for fraud and tax evasion.[4] On May 1, 1984, his trial opened in the United States District Court for the Southern District of New York.[5] On June 1, the jury convicted him on eighteen counts, acquitted him on eleven, and was unable to reach a verdict on the remaining ten counts of the indictment.[6] On June 27, he resigned his Senate seat.[7] On August 1, 1984, he was fined $69,000, and sentenced to four years in jail, by Judge David N. Edelstein.[8] On September 14, 1984, his law license was suspended.[9]
In 1985, he worked as a window salesman in Newburgh and went to live in a log cabin in West Park.[10] On September 12, 1985, a three-judge panel of the United States Court of Appeals for the Second Circuit (judges George C. Pratt, Jon O. Newman and Amalya L. Kearse) vacated most of his convictions and the four-years-in-prison sentence. The appeals court held that Pisani could not be convicted of diverting campaign funds to his personal use, because the law prohibiting this practice was enacted only after the facts of this case happened. The appeals court upheld a conviction and a suspended sentence for Pisani taking money from an escrow account of one of his clients.[11]
After his release, he worked as a salesman again, this time for an assortment of construction materials. In October 1987, he married Kathryn Godfrey, his long-time mistress and law secretary. In January 1988, he started to host a radio talk show on WVOX.[16] He also painted landscapes at his log cabin.[17]
