In Israel the trials were conducted at the city gates in front of the older men and the public not hidden away.
*** it-1 p. 518 Court, Judicial ***
The local court was situated at the gate of a city. (De 16:18; 21:19; 22:15, 24; 25:7; Ru 4:1) By “gate” is meant the open space inside the city near the gate. The gates were places where the Law was read to the congregated people and where ordinances were proclaimed. (Ne 8:1-3) At the gate it was easy to acquire witnesses to a civil matter, such as property sales, and so forth, as most persons would go in and out of the gate during the day. Also, the publicity that would be afforded any trial at the gate would tend to influence the judges toward care and justice in the trial proceedings and in their decisions. Evidently there was a place provided near the gate where the judges could comfortably preside. (Job 29:7) Samuel traveled in a circuit of Bethel, Gilgal, and Mizpah and “judged Israel at all these places,” as well as at Ramah, where his house was located.—1Sa 7:16, 17.
