TO LIFT A CURSE

So there was this lady who wanted her curse to be lifted from upon her soul. She went to a sorcerer to lift the treacherous curse. thw woman paid the sorcerer and left. Turns out the sorcerer did not remove the curse. The woman, upon hearing that her curse was not taken away, decided to sue for her money back, in a civil court. The sorcerer didnt want to have the case in a court governed by the state laws, so the sorcerer pleaded to have it in a Jewish court, so as to not have to pay back (Jewish law is strict against using sorcery, so the sorcerer wouldnt have to pay back). The Judge, a frum jew, did not allow it, saying that the monetary issues are governed by the state, and not jewish law.

This story is actually a true one, and happened recently in Israel. My question is: Would a Jewish court allow the "sorcerer" to keep the money, or would they say that since it was paid for, but wasnt done, you need to pay back? I am not so sure what a Beis din would do.
