A badatz (
Hebrew: בד״ץ plural batei din) is a major Jewish
beth din (
rabbinical court). 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. It is often used in the context of
hechsherim (
kashrut certification).
