Juries of citizens at criminal trials.

Explanation:

The Spartan government consisted of two kings that came from two different families. These positions were hereditary. It also included a council of elders, known as the gerousia, who were responsible for proposing laws. These were men over the age of 60 who held the position for life. Moreover, the government included a citizen's assembly (ekklesia), which was the highest court in Sparta. Finally, there was an executive committee of five ephors (ephoroi), or overseers, who served for one year.
