The Canons of the 217 Blessed Fathers who assembled at Carthage 30

Concerning the accused or accuser.

Likewise it seemed good that the accused, or the accusor, if (living in the same place as the accused) he fears some evil may be done him by the tumultuous multitude, may choose for himself a place near by, where the cause may be determined, and where there will be no difficulty in producing the witnesses.

Ancient Epitome of Canon XXX.

Accuser or accused may select for himself a safe place if he fears violence.
