For a number of reasons, the project did not succeed. According to Orthodox Rabbi Bernstein, the major reason for its failure was that the Orthodox rabbis insisted that the Conservative Rabbinical Assembly expel some Conservative rabbis for actions they took before the new Beit Din was formed, and the RA refused to do so (Bernstein, 1977). According to Orthodox Rabbi Emanuel Rackman, former president of the RCA, the major reason for its failure was pressure from right-wing Orthodox rabbis, who held that any cooperation between Orthodoxy and Conservatism was forbidden. In an account prepared in 1956, Rabbi Harry Halpern of the Rabbinical Assembly's "Joint Conference" wrote that negotiations between the Orthodox and Conservative were completed and agreed upon, but then a new requirement was demanded by the RCA: that the RA "impose severe sanctions" upon Conservative rabbis for actions they took before the new beth din was formed. The RA "could not assent to rigorously disciplining our members at the behest of an outside group". Per Halpern, subsequent efforts were made to cooperate with the Orthodox, but a letter from eleven Rosh Yeshivas was circulated declaring that Orthodox rabbis were forbidden to cooperate with Conservative rabbis ("Proceedings of the CJLS of the Conservative Movement 1927-1970" Vol. II, pp. 850–852).
