Lex Acilia Repetundarum was a law established in ancient Rome in 123 BC.
It provides for equites as jurors in courts overseeing senatorial class to prevent corruption abroad. It was extremely unpopular since the inferior class judges the senatorial. It was believed to be part of Gaius Gracchus' measures, suggesting that Gaius carried his chief judicial act in another tribune's name. Cicero implies in his first Verrine Oration that the measure was the work of the father Manius Acilius Glabrio, the praetor in charge of the extortion courts in 70 B.C.
