Reply To: Who is the new leader of Klal Yisrael?

Rav Moshe isn’t always the final word in America either. Roshei Yeshiva and Poskim, such as Rav Hutner, Rav Eli Meyer Bloch of Telz, the Debreciner Rav, the Chelkas Yaakov and others, sided with the Satmar Rebbe over Rav Moshe regarding the obligatory size of a mechitzah in a shul, and/or the permissibility of artificial insemination, which were the two big disagreements that those Gedoim had in halacha. It was indeed Rav Hutner who approached the Satmar Rav asking him to write a refutation to Rav Moshe’s psak about the Mechitzos.
