In Schlesinger Appeal, 404 Pa. 584, 172 A.2d 835 (1961), our Supreme Court eloquently described the importance of an impartial tribunal as follows: A fair trial in a fair tribunal is a basic requirement of due process. Fairness of course requires an absence of actual bias in the trial of cases. But our system of law has always endeavored to prevent even the probability of unfairness. To this end no man can be a judge in his own case and no man is permitted to try cases where he has an interest in the outcome .... This Court has said ... that 'every procedure which would offer a possible temptation to the average man as a judge ... not to hold the balance nice, clear, and true between the State and the accused, denies the latter due process of law.' Schlesinger Appeal, 404 Pa. 597-598, 172 A.2d 840-841.
