Rabbi Shalom Ullman disqualifies a cantor based on rabbinic testimony of adultery and theft, and asks the Chasam Sofer to confirm. The Chasam Sofer upholds the disqualification, resolving tensions between the Rema and Magen Avraham regarding removal based on rumor versus witness testimony, and rejects the cantor's claimed repentance as fraudulent, requiring relocation and sustained teshuvah before any reinstatement.
