Aristotle, Politics

[1301a] [1] These modes then are four in number, and the sectional modes also make as many others; for here again the judges for all cases may be drawn by vote from a certain class, or for all cases by lot from a certain class, or some courts may be appointed by lot and others by vote, or some courts may be composed of judges chosen by lot and by vote for the same cases. These then are the modes, as was said, corresponding to those mentioned. And there are also the same courts in combination—I mean for example some drawn from the whole body and some from a class and some from both, as for instance if the same court contained some members from the whole body and others from a class, and appointed either by lot or by vote or both. We have then stated all the modes in which it is possible for the courts to be composed; and of these the first set, drawn from all the citizens and dealing with all cases, are popular, the second, drawn from a certain class to deal with all cases, are oligarchic, and the third, drawn partly from all and partly from a certain class, are suited to an aristocracy and to a constitutional government.
