“No, but the Rabbis are the only ones who are qualified to paskan what the halacha is. “
I do not agree with this statement 100%. There are many baalebatim who are equally qualified in their Torah knowledge. BUT (and this is a big caveat) those laypeople do not have the halachic AUTHORITY to pasken, even when they do know the halacha. And wasn’t one of our Gedolim (was it the Chofetz Chaim??? I might be wrong about that) a man who never even received smicha? Whoever that talmid chochom was, I doubt any of us would have the nerve to accuse him of being less qualified than a “bona fide” rov.
