There’s a well known story of 2 rabbonim who paskened differently on the status of a chicken.
When they were both served the meal, the rav who assured the chicken encountered an “out of this world” experience: the chicken kept falling off his fork. The rav who matired it had no problem.
For one rav it was assur to it, for the other it was permissible.
So there’s no such thing as a “bad” psak, just a different one.
There’s also the story how this one rav was correct and the others were incorrect, yet ???? accepted the majority’s decision.
(I’m rushing, so if someone can embellish that would be great)
???? ?? ????? ??? and ???? ????? ???? ????? ??-??.
