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. ”
