M. Tullius Cicero Pro A. Cluentio 75

[75] The judges rise to give decisions, when Oppianicus said, as he had at that time a right to do, that he wished the votes to be given openly; his object being that Stalenus might know what was to be paid to each judge. There were different kinds of judges, a few were bribed, but all were unfavorable. As men who are accustomed to receive bribes in the Campus Martius are usually exceedingly hostile to those candidates whose money they think is kept back, so the judges of the same sort were then very indignant against this defendant. The others considered him very guilty, but they waited for the votes of those who they thought had been bribed, that by seeing their votes they might judge who it was that they had been bribed by. 28
  Behold now—the lots were drawn with such a result that Bulbus, Stalenus, and Gutta were the first who were, to deliver their opinions. There was the greatest anxiety on the part of every one to see what vote would be given by these worthless and corrupt judges. And they all condemn him without the slightest hesitation.
