Heliaia (Greek: ἡλιαία) or Halia (Greek: ἁλία) was the supreme court of ancient Athens. Τhe generally held scientific view is that the court drew its name from the ancient Greek verb , which means συναθροίζεσθαι, namely congregate. Another version is that the court took its name from the fact that the hearings were taking place outdoors, under the sun. Heliaia was also called big ecclesia. Inititally, this was the name of the place where the hearings were convoked, but later this appellation included the court as wellThe Helios.
The judges were called heliasts (ἡλιασταί) or dikasts (δικασταί, ὀμωμοκότες = those who swore on, namely the jurors). The operation of judging was called ἡλιάζεσθαι (= δικάζειν).
The 6.000 were drawn from the 10 tribes (each tribe was offering 600 members) and they were then divided into chambers of 600 jurymen, 500 or 501 of whom were regular members and the rest constituted alternate juror. In exceptional case the court could go into plenary sessionsAndocides, Speeches, 1.17 and Mogens Herman Hansen, The Athenian Ecclesia: A Collection of Articles 1983-1989, page 260. Sometimes the chambers were comprising from 201 to 401 members or 1001 to 1501 members. After the choosing by lot, the heliasts had to take once every year the heliasts' oathThe Helios. After the swearing-in, the jurors were receiving one box-wood ticket, with their own names and that of their father and deme written on it, and one letter of the alphabet as far as kappa Demosthenes, On the Crown, 210and the jurors of each tribe were divided into ten sections, approximately an equal number under each letter.Aristotle, Constitution of Athens, 63.3.
Taking the jurisdicion over the so-called graphe paranomon, Heliaia replaced Areios Pagos in the execution of the legal control of the decisions of ecclesia. Until Ephialtes' reforms Areios Pagos had the duty of guarding the laws and to keep watch over the greatest and the most important of the affairs of stateAristotle, Constitution of Athens, 8.1.
The hegemon (ἡγεμών) of the court was responsible for gathering the suits and the complaints. After holding a preliminary investigation, he also had to subpoena the litigant parties and the witnesses before the jury. In the morning of the hearing day, the hegemon should determine by lot the chamber that would judge the case as well as the place where the jury would be convened. After the formation of the jury, the hegemon had to submit the conclusions of his preliminary investigation, announcing and defining the litigation, on which the court should decide. Then, it was the time for the plaintiff, the defendant and the witnesses to be heard. The arguments were exposed by the litigants themselves, without the legal support of a lawyer, in the form of an exchange of single speeches timed by water clock. In a public suit each litigant had three hours to speak, whereas they had much less in private suits (though here it was in proportion to the amount of money at stake). In this way the judicial cases became a vehement fight of impressions, since the jurors did not constitute a little group of mature citizens, such as the Council of Areios Pagos, which was interested only for the right application of the law. Additionally, before the Chambers of Heliaia each citizen had to become an effective orator and to act solely in his capacity as citizen, in order to protect his interests and to enforce his viewsStephen Usher, The Orations in Ancient Attica in The Orations in the Modern Educational Systems, page 184.
Decisions were made by voting without any time set aside for deliberation. Nothing, however, stopped jurors from talking informally amongst themselves during the voting procedure and juries could be rowdy shouting out their disapproval or disbelief of things said by the litigants. This may have had some role in building a consensus. The voting procedure was public and transparent. Each heliast was receiving two votes, one "not guilty" and one "guilty". Then, the herald (κήρυκας) should, first, ask the heliasts if they wanted to submit any objections against the witnesses and, then, he should call them to cast their votes in two different amphoras, one of copper for the "non-guilty" votes and one of wood for the "guilty" votes. The voting was secretR.K Sinclair, Democracy and Participation in Athens, page 20, since each juror had to cover with his fingers the vote, so that nobody sees, in which amphora he throws it. In the civil cases the voting procedure was different, because the amphoras were as many as the litigant parties and the jurors had to vindicate one of them, by casting their vote.
After the votes were counted, the herald was annoncing the final result. In case of equality in votes, the defendant was acquitted, because he was considered to enjoy "the vote of Athena".
Heliasts could impose either fines (for civil and penal cases) either "corporeal sentences" (only for penal cases). The fines of Heliaia were higher than the fines of the archons. The lato sensu "corporeal sentences" included death, imprisonment (for the non-Athenian citizens), atimia (sometimes along with confiscation) and exile (ἀειφυγία).
Socrates was accused for impiety by Meletus, Anytus and Lycon. His trial took place in 399 BC and the jury found him guilty with 280 votes to 220Comments on Socrates' Apology (in Greek), page 17. His death sentence was decided in a second voting,which was even worse for the philosopher. Nonetheless, Socrates did not lose his calm demeanor and, although during the trial he could propose to the jury his self-exile, he did not do it, since life away from his beloved city was pointless for him.
According to PlutarchPlutarch, Pericles, 32.1 and 35.1, Pericles faced twice serious accusations. The first one just before the eruption of the Peloponnesian War and the second one during the first year of the war, when he was punished with a fine, the amount of which was either fifteen or fifty talents. Before the war a bill was passed, on motion of Dracontides, according to which Pericles should deposit his accounts of public moneys with the prytanes and the jurors should decide upon his case with ballots which had lain upon the altar of the goddess on the acropolis. This clause of the bill was however amended with the motion that the case be tried before fifteen hundred jurors in the ordinary way, whether one wanted to call it a prosecution for embezzlement and bribery, or malversation.
α. In Argos the place where its court was seated was also called ἁλιαία.
β. Sun = ἥλιος and the verb ἡλιοῦσθαι (passive voice) = enjoy the sun.
γ. According to Mogens Herman Hansen, The Athenian Ecclesia: A Collection of Articles 1983-1989, page 260, apart from Plutarch who quotes ths Ath. Pol. there is no otherevidence that Heliaia was a court of appeal and the scanty contemporary sources indicate that it was a court of first instance.
δ. When certain chambers were merged. This was the case of Pericles' trialSee The Helios.
ε. The cases of private international law were initially judged by the session of the Athenian alliance in DelosThe Helios.
στ. This was not a judge or a juror, but a kind of archon, chosen by lot or by ordination for about a monthThe Helios, article Hegemony of the court.
ζ. That is why the profession of the logoglapher, namely professional authors of judicial discourse, such as Lysias, flourished in ancient AthensStephen Usher, The Orations in Ancient Attica in The Orations in the Modern Educational Systems, page 183.
