Theomnestus and Apollodorus Against Neaera (90)

And the law requires the presidents[*] to set out the ballotboxes and to give the ballots to the people as they come up before the non-citizens have come in and the barriers[*] have been removed, in order that every one of the citizens, being absolutely free from interference, may form his own judgement regarding the one whom he is about to make a citizen, whether the one about to be so adopted is worthy of the gift. Furthermore, after this the law permits to any Athenian who wishes to prefer it an indictment for illegality against the candidate, and he may come into court and prove that the person in question is not worthy of the gift, but has been made a citizen contrary to the laws.
