The code of honor agreed on by mutual understanding and tacitly accepted by members of the legal profession, especially by the bar. Wharton.
Eum qui nocentem infamat, non est aequum et bonum ob eam rem condemnari; delicta enim nocentium nota esse oportet et expedit. It is not just and proper that he who speaks ill of a bad man should be condemned on that account; for it is fitting and expedient that the crimes of bad men should be known. Dig. 47, 10, 17; 1 Bl. Comm. 125.
