Is there any case law where a judge was biased or prejudiced?

Ricci v. Key Bancshares of Maine, Inc., 111 F.R.D. 369, 373 n. 4 (D.Me.1986). The Appellants have failed to show even a reasonable suspicion that the judge was biased or prejudiced. In the absence of such a showing, the Appellants were simply engaging in a fishing expedition. See Lyeth v.

The bankruptcy court properly denied discovery.
