to Brooklyn,
The problem, as stated above, is that the last ” Lipa ban ” caused a large financial hardship and, as Rav Kaminetsky of Philadelphia later admitted, he never actually read ( let alone investigated ) what he was signing. While he was the only one to admit it, there must have been others among the signatories and it results in other kol korehs being ignored. Gadolim are not angels and all-knowing in all areas. Going to a rav for all decisions is a chassidish, not a yeshivish custom.
