How Were Decisions Made, Who Made Them And How Did They Get Into Their Position Of Power?
Usually the head male of the house made the decisions, but if it was a legal matter, depending on the severity of the issue, a tribune or praetor could make a decision. If it was a serious national matter such as treason, the senate would hear the case depending on guilt and innocence. During the principate, then ultimate national decision was made by the emperor.
