Rabbinic Authority: The Vision and the Reality is a 21st-century work about the parameters and scope of rabbinic authority in general, and the workings of the institution of the beit din (Jewish court of law) in particular. In the work’s five volumes, the author presents rulings in cases of Jewish civil law that he handed down as a member of a beit din panel. Volume V discusses utilizing the technique of the double halakhic doubt (“sefek sefeika de’dina”) as a vehicle to void a marriage where necessary.
