Reply To: New Brooklyn Eruv: Time to Accept?

@youdontsay
When I said 3 mechitzos, I was referring to the 3 redundant tzuros hapesech put up by 3 independent batei dininim.
The Teshuvos HaRashba’s psak is accepted, not to use a tzuras hapesach for a RH”R deOirsissa. If shishim riboi is required to constitute a RH”R deOiraissa according to roiv Roishoinim (which I believe is what you were touching on,) depends on how you count the shitois. This is the famous machloikes of the Mishkonois Yaakov and the Bais Ephraim. See SH”A OR”CH soman 364 se’if 2, Bais Ephraim OR”CH siman 26 and Chazon Ish OR”CH siman 107 ois 4. [The Mishkanois Yaakov became famous with this teshuvah of his in disagreement with the renowned gadol hadol R’ Ephraim Zalman Margoliois z”l.]
(I think?)
