English: A beit din that is in doubt whether they erred in a ruling or not — they do not bring an asham talui, as it is said “and the sin becomes known” — they are not liable until it becomes known.
No asham talui for doubtful communal hora’ah — communal chatas requires definite knowledge of the sin; doubt does not trigger asham talui for the court.
A beit din that is merely in doubt whether its ruling was erroneous does not bring an asham talui. The verse’s language “and the sin becomes known” demands actual revelation of the specific transgression. Uncertainty about whether any error occurred leaves the court outside the liability of both the regular communal bull and the suspended-guilt offering.
