Whether the extrajudicial-source principle applies to recusal motions under 28 U.S.C. § 455(a).
Holding
Yes. An extrajudicial source is a significant, and often determinative, factor under § 455(a), although it is neither a necessary nor a sufficient condition for recusal.
Reasoning
Section 455(a) requires recusal when a judge's impartiality “might reasonably be questioned,” while § 455(b)(1) requires recusal for personal bias or prejudice. The 1974 revision broadened recusal law by adding § 455(a)'s objective appearance standard, but it did not eliminate the established distinction between ordinary judicial judgments and wrongful bias or partiality.
The Court rejected the argument that the word “personal” in § 455(b)(1) creates a rigid division between extrajudicial bias and bias acquired through judicial work. Bias and prejudice are pejorative terms: they refer to an unfavorable disposition that is wrongful because it is undeserved, rests on improper knowledge, or is excessive. A judge may properly form strong views about a party from evidence presented in a case without becoming biased in the statutory sense.
The same understanding applies to “partiality” in § 455(a). Impartiality does not demand “child-like innocence.” Judges necessarily form opinions from the evidence, arguments, and prior proceedings before them, and a reasonable observer would not treat every such opinion as an appearance of improper partiality.
Section 455(a) overlaps with the more specific provisions in § 455(b). In that overlap, the Court concluded that § 455(a) should not ordinarily be read to erase a limitation that governs the particular subject addressed in § 455(b)(1). The objective feature of § 455(a) means actual subjective bias need not be proved, but a disposition based on properly acquired judicial information ordinarily does not reasonably appear to be improper bias.
The Court emphasized that “extrajudicial source” is better understood as a factor than as an absolute doctrine. An outside source does not automatically establish disqualifying bias, because a judge's general views of law or policy may be proper. Conversely, a judicially acquired view can require recusal in the rare case where it shows deep-seated favoritism or antagonism that makes fair judgment impossible.
