Guest Post by RaP: [Updated with part 2 and 3]
R. Aron Schechter's signature on the "kol koreh"  against AMW is a total joke if one simply remembers what an ongoing chillul  HaShem he has caused for almost 35 years by refusing the summonses of various  batei din and of Rav Moshe Feinstein Z"TL to come to a din Torah, as the  attached documents attest.
(The attached documents, long available online,  speak for themselves and explain the hypocrisy and chillul Hashem.)

Part 2: Weiss/Dodelson: Double Standards of the  Signers:
It  is well known that Rav Aron Schechter is the "first among equals" on  the  current American Aguda's Moetzes and that he has the final veto on  any decision.  Thus his signature on the "kol koreh" on behalf of the  Dodelsons-Kotlers and  against the Weisses-Feinsteins is not just  "another signature" but it is  "the signature", meaning that once  he signs, then automatically  his strongest allies Rav Yaakov Perlow  and Rav Aron Feldman also sign. The other  signers are just weaker  add-ons without the prestige and automatic pull of the  Aron  Schechter-Yaakov Perlow-Aron Feldman (Chaim Berlin alumni) troika. 
Rav Aron Schechter's signature on the anti-Weiss "kol koreh"  is its strategic key and paradoxically also its weakest link,  because of the fact that Rav Aron Schechter himself decades ago set the trend of  refusing to appear before bais din -- any bais din -- multiple  times.
There  were not one, not two, not three, but four hazmonas (see attached   copies of originals) that Rav Aron Schechter ignored from the bais din  of the  Hisachdus HaRabbanim (the Central Rabbinical  Congress of  Satmar founded by Rav Yoel Teitelbaum ZT"L a person and  group greatly  respected by Chaim Berliners -- but not when they got summoned by  its  bais din!) besides the hazmona from Rav Moshe Feinstein ZT"L at  that  time the head of the Moetzes and known at that time by all as the Gadol   HaDor.
Rav  Aron Schechter remains steadfast in his own refusal to come to bais din   while at the same time it is expected that the Weisses-Feinsteins  should "come  running" to settle.
In  addition to which,extra-judicial severe threats of an   ambiguous "blood bath" were used by Rav Carlebach's opponents on  behalf  of Rav Aron Schechter for which they were excoriated by leading  Rabbanim,  such as Rav Dr. Shamshon Weiss Z"L (see his attached letter)  of Washington  Heights (see his obituary in  
New York Times obituary for Rav Weiss ). Now if that is not called a double standard and hypocrisy, then nothing  is.
One  thing is certain, that the Weisses-Feinsteins are being subjected to   the same cynical brutal tactics, of all-out war, as was Rav Shlomo  Carlebach and  in both cases Rav Aron Schechter is at the center of the  fight. Remove him and  his signature from the "kol koreh" and the whole  case of the Dodelsons collapses  with its "krumme heterim" to abuse the  Weisses.
It  is time for Rav Aron Schechter to remove his signature, or for it   to be declared null and void, on the abusive anti-Weiss "kol koreh"  and  be called on his unacceptable and untenable actions and reprimanded en  masse  for them by the Torah world. There is nothing to fear for  standing up for the  Emes. The time for such "old school" bullying  tactics "in the name of halacha"  has come to an end.
Part 3: Weiss/Dodelson: Double Standards of the Signers
What type of people have the audacity to sign on to crazy "kol korehs" to destroy fellow-Jews befitting Amalek as in this case against the Weisses-Feinsteins, when they themselves have never responded to far more serious dinei Torah and multiple summonses from batei din and pleas from Gedolim (from Rav Y.Y. Ruderman, Rav Yaakov Kaminetsky, Rav M. Gifter, Rav Schwab Zichronam Livracha, and others) against themselves?
What kind of people have one standard, or lack of standard, for themselves, but expect others to follow an entirely different set of "holier than thou" declarations? How about one set of standards for everyone? Not for some it would seem.
There should be no doubt about the status of Rav Aron Schechter as a lo tzayis dino (one in contempt of bais din, see attached documents), in this case the batei din of Rav Moshe Feinstein ZT"L and of the CRC's founded by Rav Yoel Teitelbaum. The refusal of Rav Aron Schechter (what was/is he afraid of, that he would LOSE?) to bring to closure the matter of the genuine dinei Torah initiated by Rav Shlomo Carlebach has cost him and the Chaim Berlin people dearly. The core of the case revolves around both monetary issues relating to severance pay as well as to who is still supposed to be the authorized mashgiach ruchani of the Chaim Berlin yeshiva. 
Rav Moshe Feinstein stated and ruled (see above documents) that as long as the matter has not been brought to closure, that Rav Carlebach remains as the only legitimate mashgiach ruchani and that no one is allowed to replace him. Rav Moshe Feinstein further ruled that as long as the matter is not resolved in bais din, then a regular salary is still owed to Rav Carlebach which after 35 years would amount to quite a big sum since Rav Carlebach is still B"H alive and active and has never abandoned his title and claims.
To re-affirm his support for Rav Carlebach in the midst of this ongoing situation, Rav Moshe Feinstein granted him a personal semicha (see attached).
But it goes further than that, a few years back Chaim Berlin yeshiva in Brooklyn was faced with a challenge from the nearby Veretzky yeshiva, that is under the control of the Rabbonim and Balebatim who run the "Landaus minyan" in Flatbush. The Chaim Berlin people had thought they had "automatic rights" to a key adjacent corner property but were surprised to find that Veretzky had beaten them and had submitted a winning offer. 
Of all the absurd scenarios of self-delusion, the Chaim Berlin people imagined they could commence with a din Torah against the Veretzky people. To the shock and consternation of all, the Veretzky people hired an expert to'en who basically formulated a halachic argument (see attached) based on the events of Chaim Berlin refusing to respond to Rav Carlebach's din torah and the various hazmonas (see above originals) that were issued. 
The to'en for Veretzky's formulation al pi din Torah states quite clearly that the Chaim Berlin people are "lo tzayis dino" (see his attached three page argument). Not just that, but to make sure his case was heard, it was sent to several important batei din with all related documentation. Behind the scenes the Chaim Berliners were humiliated and frantic, supposedly even Rav Elyashiv ZT"L was consulted on the matter, and basically his response was that "people who do not go to a din Torah when they are summoned, cannot summon others to a din Torah" until such time that they settle all prior dinei Torah. And so the matter has rested with Veretzky getting its way teaching an important lesson that has evidently still not been learned, because now "new avenues" are found via fake "kol korehs" that are not worth the paper they are written on.
The moral of the story is that we are dealing with very dangerous people here. The ruthlessness and cynicism of the Dodelsons and their Kotler puppet masters is only exceeded by the cynicism and brutality of Rav Aron Schechter and the Chaim Berlin people who are too intimidated to stand up against his floundering ways (too many to count, such as his support for Schick, Hersh, Tropper-Guma-Kaplan, Kranczer etc that ALL blew up in his face).
It is time for American Torah Jewry to wake up and realize that they are being led down the garden path by terrible Pied Pipers who worship only one thing: BIG Money. Money talks! Forget about HKB"H, Rav Moshe Feinstein, the CRC, Halacha, all the old-time great Gedolim of America, but forge signatures of fake "kol korehs" and join the MOs and ORA and get into the NY Post, blast away at the family of Rav Moshe Feinstein ZT"L because you want to set up a "new world order" of money worshipping roshei yeshiva etc. is how the Schechter-Perlow-Feldman troika come across. And just as the moral and human failures Schick and Hersh and Tropper and Guma and Thomas Kaplan and Kleinman who all had/have plenty of money to back themselves up and "bribe" their way to top influence, the Dodelsons are loaded and using their wealth to wage an all-out war for a "get" by trying to destroy the Weisses-Feinsteins that is hurting all of Klal Yisroel. 
Wake up everyone before you all fall victim to this modern-day Egel HaZahav Golden Calf as the new fake and false "god"!
