The law passed in 169 BC on the proposal of the tribune Q. Voconius Saxa, supported by the elder Cato, which forbade citizens of the highest census class from instituting a woman as heir and limited the size of any legacy to a woman. Cicero cites it repeatedly (Verr. 2.1.106-114; Cat. mai. 14) as a classic example of how new law cannot disturb dispositions made before its enactment.
