[If] the court ruled, and one of them knew that they had erred, and he said to them, “You are mistaken”; or [if] the most dis-tinguished [member] of the court was not there, or [if] one of them was a convert, or a mamzer, or a Nesinite, or an elder who never had (lit., saw for himself) children —- these are exempt; for it says here edah and it says further on edah, just as [in the case of the] edah which is said further on, they must all be fit to rule, so too, the edah which is said here [means] until they are all fit for legal ruling.  [If] the court ruled inadvertently, and all the people acted inadvertently —- they bring a bull.  [If they ruled] willfully and [the people] acted inadvertently —- they must [each] bring a she-lamb or a she-goat. [If they ruled] inadvertently, and [the people] acted willfully —- they are exempt.
