Public Notice from Vaad HaRabbonim Haolami LeInyonei Giyur
founded by HaRav Chaim Kreiswirth zt"l
According to established halacha, genuine acceptance of mitzvas, in full, by a conversion candidate at the time of the conversion is an essential condition in order for the conversion to be valid. Therefore if it comes to light that the "convert" did not undertake proper mitzvah observance at the time of the conversion, even if later he does undertake mitzvas, the conversion is not valid under any circumstances. This halacha has been thoroughly clarified and does not require further explanation in this notice.
Therefore we hereby commend and support the reputable dayanim of the High Rabbinical Court of Jerusalem, HaRav Avrohom Sherman, HaRav Chagai Izerer and HaRav Avrohom Sheinfeld shlita, as well as HaRav Avraham Attia shlita, a dayan at the Ashdod Beis Din, who resolutely determined in their respective rulings that conversion without accepting mitzvas is not conversion, and that a conversion performed by unworthy dayanim who do not bother to look into whether there was a genuine acceptance of mitzvas is not a valid conversion at all, and the "convert" has a din of a non-Jew for all intents and purposes.
As such this is a sacred call to the Chief Rabbis and all other rabbonim and dayanim in Israel to publicize their support for this ruling and to fulfill the Torah's exhortation, "Do not be afraid in the face of any man" (Devorim 1:17) in order to stop non-Jews from being assimilated into Am Yisroel.
