shabbat 17

the sword that blocked the exit and forced a resolution.

but forced resolutions are unacceptable.

and dissent leaks out


(in list of decrees that Hillel and Shammai issued is the story that a sword was stuck in the door preventing exit until the matter was resolved. but the people didn't accept it, only when the students of Hillel & Shammai issued the decree was it taken up. one of the cases was about the purity status of liquid that leaked out of grapes. for english translation of this talmud page, see here)
