It was decided to elect a new decemvirate. They generally do not believe that a second decemvirate ever took place. The first decemvirate completed the first ten codes in 450 BC. In 2005, historian Gary Forsythe dismissed the second decemvirate as unhistorical. A second decemvirate is said to have added two further tablets in 449 BC. Mommsen argued that the decemvirate must have been open to plebeians from the beginning. The Second Decemvirate seemed to be constituted equally by patricians and by plebeians, like Merenda. Under imperial law, the decemvirate had jurisdiction in capital cases.
