beninugman,rebdoniel, Sam2 and others: After all is said and done, what differentiates the Langer case from what Rav Sherman (and Rav Attyia) is not the halachic basis of the different epiaodes but how it was done. AS I said many times, Rav Goren did it ONCE (invalidating a previous geirus) but Rav Sherman invalidated EVERY single geirus by Rav Druckman. That alone showed why the psak din of Rav Sherman was erroneous. he did it by “passeling’ the whole Bais Din- and this is why it had all the hallmarks of chareidi overreach.Furthermore, a dayan of Rav Sherman’s own Bais Din (Rav Shlomo Dichowsky)objected to his psak.
There is more,much more on this in various writings (check out, Dov Zakheim’s -Transforming Israel’s Chief Rabbinate, November 2012)but the bottom line is that the chareidi leadership in Israel was-and still is- intent on controlling all aspects of the Rabbinical process in Israel and that they -and only they- can tell us what is right or not.As an example of this power play, did you know that many chareidi Rabbis would consider a Gyores who wears pants or doesn’t cover her hair as not adhering to kabbolos mitzvos? This surely was never meant to be the baseline.
