Ordinarily, be aid not decide causes as a judge, but prepared the grounds of decision for the judge and sent to, him the questions to be decided between the parties. The judge was always chosen by the parties, either directly, or by rejecting, under certain rules and limitations, the persons proposes to them by the praetor.
