Qitzur Shulchan Arukh – 181:1
סִימָן קפא – הִלְכוֹת הִלְכוֹת טוֹעֵן וְנִטְעָן וְעֵדוּת
181: Laws of Claimants, Defendants and Testimony
When a disagreement arises between two people, it is better for them to compromise for good, and each give in something against their friend, in order to avoid the lowering of the courts as much as possible.
This relates to the middah of maavir al midosav. Insisting on strict justice rather than seeking more of a win-win resolution lowers the court. It’s a shift from covenantal thinking to contractual justice.
