A person's protests are not accepted in the following situation. Reuven sold a field to Shimon, and Levi was one of the witnesses who signed the deed of sale. Afterwards, Levi came and protested Shimon's ownership of the field, claiming that Reuven stole it from him. We do not heed Levi's protest, nor do we pay attention to the proofs he brings concerning his ownership of that field. He has forfeited all of his rights to it. For we tell him: "How could you serve as a witness to the sale and then come and protest?" Similar concepts apply if Levi gives testimony in a legal document that speaks of "the field belonging to Reuven on the east" or "... on the north." Since he referred to that field as an identification marker for the sake of another person and recorded this testimony in a legal document, he forfeited his right to it and cannot issue a protest concerning it. For we tell him: "How could you serve as a witness in this legal document that mentions this field being near another field and then issue a protest concerning it?"
