Hugo Black,
In re Murchison — Opinion of the Court
“ It would be very strange if our system of law permitted a judge to act as a grand jury and then try the very persons accused as a result of his investigations. Perhaps no State has ever forced a defendant to accept grand jurors as proper trial jurors to pass on charges growing out of their hearings. [7] A single 'judge-grand jury' is even more a part of the accusatory process than an ordinary lay grand juror. Having been a part of that process a judge cannot be, in the very nature of things, wholly disinterested in the conviction or acquittal of those accused. ”
