From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
As little does any special influence seem to have belonged to the kings; they acted chiefly as supreme judges, and they were frequently so named (shofetes, -praetores-). The power of the general was greater. Isocrates, the senior contemporary of Aristotle, says that the Carthaginians had an oligarchical government at home, but a monarchical government in the field; and thus the office of the Carthaginian general may be correctly described by Roman writers as a dictatorship, although the gerusiasts attached to him must have practically at least restricted his power and, after he had laid down his office, a regular official reckoning--unknown among the Romans--awaited him.
There existed no fixed term of office for the general, and for this very reason he was doubtless different from the annual king, from whom Aristotle also expressly distinguishes him. The combination however of several offices in one person was not unusual among the Carthaginians, and it is not therefore surprising that often the same person appears as at once general and shofete.
