4289 And how, O Emperor, are we to settle a matter on which you have already declared your judgment, and have even promulgated laws, so that it is not open to any one to judge otherwise? But when you laid down this law for others, you laid it down for yourself as well. For the Emperor is the first to keep the laws which he passes. Do you, then, wish me to try how those who are chosen as judges will either come, contrary to your decision, or at least excuse themselves, saying that they cannot act against so severe and so stringent a law of the Emperor?
