Summary

Horace Gray Moran v. Dillingham — Opinion of the Court

The intention of congress in enacting that no judge before whom 'a cause or question may have been tried or heard' in a district or circuit court 'shall sit on the trial or hearing of such cause or question' in the circuit court of appeals, manifestly, was to require that court to be constituted of judges uncommitted and uninfluenced by having expressed or formed an opinion in the court of the first instance.

Horace Gray Moran v. Dillingham — Opinion of the Court

And as 'a cause,' in its usual and natural meaning, includes all questions that have arisen or may arise in it, there is strong reason for holding that a judge who has once heard the cause, either upon the law or upon the fac s, in the court of first instance, is thenceforth disqualified to take part, in the circuit court of appeals, at the hearing and decision of the cause, or of any question arising therein.
