We talk about a seruv here but does it really mean anything?
What about those rabanim who will not uphold the seruv? I am talking about cases (I personally know some) where one side violated Beis Din, went against Beis Din orders, brought the matter to secular court after being in Beis Din, or would not go to Beis Din when asked to ect. Then the Beis Din did nothing to enforce their ruling! They did not call a seruv ect. those people still were counted as part of the minyan, got aliyos ect.
What good is a seruv if it is not enforced?
