When litigants sign a Shtar Borrerus (Deed of Arbitration) in Beis Din, it usually states that the Dayanim are given the authority to rule either according to the strict Din or by way of Peshoroh (compromise). Why does Beis Din not rule always according to the Din?
Sometimes a litigant requests that it say only din.
1] Since we cannot be absolutely certain that our shikkul da’as is correct (if R’ Shimon bar Yochai said we do not have the wisdom to rule dinei momonos accurately nowadays, what can we add to that?), we add this in so that if we inadvertently made a slight deviation from the Halachah the ruling should be effective under the category of peshoro krovoh lodin.
