This case involves the criminal conviction of an attorney, Stephen Goot, on a two-count indictment, for "fixing" driving-under-the-influence (DUI) cases. One count, under what is commonly called the RICO statute, was for racketeering and the other was a corresponding conspiracy count. See 18 U.S.C. Â§ 1962(c) & (d). For reversal, Goot argues the district court erred in (1) refusing to disqualify the United States Attorneys office; (2) refusing to grant a hearing on the disqualification issue; (3) imposing an improper sentence; (4) excluding impeachment testimony; (5) admitting testimony of others convictions; (6) denying a motion for acquittal based upon various aspects of the evidentiary proof of a RICO violation; (7) instructing the jury that the Lake County prosecutors office can be an "enterprise"; and (8) refusing to instruct the jury on the definition of reasonable doubt.
