Lucius Cassius Longinus
In 137, Scipio supported a bill made by the tribune of the plebs Lucius Cassius Longinus Ravilla, which made compulsory the use of secret ballots in criminal cases brought before the popular assembly (except for high treason). It is likely that since the extortion court did not work as he had expected, Scipio thought that the more malleable popular juries would be better suited to convict his opponents. Besides, in 136, Scipio's enemy Marcus Aemilius Lepidus Porcina was prosecuted and condemned before the popular assembly.
