Montesquieu

Under the consu­late of Acilius Glabrio and Piso, the Acilian law1 was made in order to put an end to intri­gues. Dio says2 that the senate got the consuls to pro­pose it, because the tri­bune C. Cornelius had deci­ded to have ter­ri­ble penal­ties ins­ti­tu­ted against this crime, to which the peo­ple were much incli­ned. The senate thought that immo­de­rate punish­ments would indeed plant ter­ror in peo­ple’s minds, but would have the effect that no one would be found any more to pro­se­cute or condemn, whe­reas by pro­po­sing modest penal­ties they would have jud­ges and accu­sers.

The guilty were sentenced to a fine, and could no longer be admitted to the order of senators or named to any magistracy (Dio, book XXXVI).
