Smith v. Beckman
In Smith v. Beckman, 683 P.2d 1214 (Colo. Ct. App. 1984), the judge presiding at defendant's trial was married to a deputy district attorney in the same county as the deputy district attorney prosecuting the case.
The Colorado Court of Appeals determined that the judge's recusal was required by Canons 2 and 3(C) of the Colorado Code of Judicial Conduct, "which provide that a judge should avoid the appearance of impropriety and disqualify himself in any case in which his impartiality might reasonably be questioned." Id. at 1215.
