Gedolim Not Being Aware

Daf Hashavua

Gittin 81b

והאמר ר' יוחנן הלכה כסתם משנה

-אמוראי נינהו ואליבא דר' יוחנן

The Chasam Sofer (Shu"t E.H.2:71) explains

that all agree that R.Yochanan said Halacha

K'stam Mishna. The Talmidim argue if it is

also applicable when there is a Machlokeh

in a Breisa*.

According to Rabah B.B.Ch.. R.Yochanan

would agree that the Halacha is not like the

Stam Mishna. It is possible Rebbe wasn't aware

of the Machlokeh in the Breisa and had he known

of it he would not have paskened like the Stam.

The othe Amorei argues and holds even when

the Machlokeh is in a Breisa the Halacha is 

like the Stam because Rebbe knew of every

Machlokeh even if mentioned in a Breisa.

The Ch.S. continues that this Machlokeh is

only on Rebbe who was a Gavra Rabah

therefore one Amorei holds that Rebbe knew

every Shita. On other Gedolim, even the 

Amorei will agree that it is possible for 

them not being aware of 

another Shita and had they been aware of it 

they might have changed their mind.

(see Rema Ch.M. 25:2)

*"ובזה מיושב קושי' עצומה מה שמקשו מרבב"ח

(חולין מ"ג ע"א) דס"ל הלכה כסתם משנה נגד משנה אחריתי
