It was this Leo who first persuaded Justinian to barter justice for money.

When this man had once discovered these means of plunder, he never stopped.

The evil spread and reached such a height that, if anyone desired to come off victorious in an unjust cause against an honest man, he immediately repaired to Leo, and, promising to give half of his claim to be divided between the latter and the Emperor, left the palace, having already gained his cause, contrary to all principles of right and justice.

In this manner Leo acquired a vast fortune, and a great quantity of land, and became the chief cause of the ruin of the State.
There was no longer any security in contracts, in law, in oaths, in written documents, in any penalty agreed upon, or in any other security, unless money had been previously given to Leo and the Emperor.

Nor was even this method certain, for Justinian would accept bribes from both parties; and, after having drained the pockets of both of those who had put confidence in him, he was not ashamed to cheat one or other of them (no matter which), for, in his eyes, there was nothing disgraceful in playing a double part, provided only that it turned out profitable for him.
Such a man was Justinian..
