Claim: The term badatz is a modern one, and in Israel, it is often used to refer to the Badatz of the Edah HaChareidis (a large ultra-Orthodox Jewish communal organization based in Jerusalem).
Evidence: The term is a modern one, and is an acronym for beit din tzedek ("court of Justice"). In Israel, the term Badatz is often used to refer to the Badatz of the Edah HaChareidis; however, it is not the title of this group, and other batei din use the title as well. The Charedi Council of Jerusalem (Hebrew: העדה החרדית‎, ha-Edah ha-Charedit, Ashkenazi pronunciation: ha-Aideh Charaidis or ha-Eido ha-Chareidis; "Congregation of God-Fearers") is a large ultra-Orthodox Jewish communal organization based in Jerusalem, with several thousands affiliated households.
