Leges Genuciae
Leges Genuciae (also Lex Genucia or Lex Genucia de feneratione) were laws passed in 342 BC by Tribune of the Plebs Lucius Genucius. These laws covered several topics: they banned lending that carried interest, which soon was not enforced; they forbade holding two magistracies at the same time or within the next 10 years (until 332 BC); and lastly, they required at least one consul to be a plebeian. The first time both consuls were plebeian was in 172 BC. By then, that provision was the only one that continued to be enforced.
