[Avodah] hoist by his editor's petard

[David Riceman]

I've started leafing through the Rogatchover haggadah.  There's 
something there relevant to a subject we discussed several years ago.

What value is a psak lacking explanation? Rabbi Rosen (p. 22 column 2) 
rules that it lacks precedential value: "horaah kol zman shelo nisbarer 
lanu ta'amo ein tzarich lachush l'dvarav klal.  Ki haoser v'hamtamei 
tzarich l'havi ra'ayah".

Ironically the editor doesn't cite Rabbi Rosen's explanation.  The 
source is "Likutei basar Likutei, ed. R. Y. Mandelkern, letter 8, pp. 
49-50".  Does anyone have access to this book? If so, can you post the 
reasoning?

Thanks,

David Riceman
