The Chasam Sofer rules that the borrower's litigation expenses were improperly awarded without proof or beis din assessment, the lender's agent has no standing to demand disqualification of a witness, and the borrower cannot be disqualified from testimony, oaths, or communal appointments since there is no proof of forgery, he has a valid excuse, and even a proven forger is not disqualified from testimony or oaths in other contexts.
