Sephardic Chief Rabbi Yitzhak Yosef, at a demonstration of rabbis against Minister Matan Kahana's conversion reforms, quoted Tzohar chairman Rabbi David Stav as saying that it is permissible to convert someone who does not accept the yoke of the commandments. However, Rabbi Stav never said anything to that effect.
The original quote, which Rabbi Stav said in 2008 at a conference of the Israel Democracy Institute, reads as follows: "If a person says I am traditional, but he is really willing to be traditional, I accept him. Like the friend, the traditional friend, who comes to a synagogue and can make a kiddush on Shabbat."
However, Rabbi Stav was not giving his own opinion, but stating what he had heard from another rabbi from a community which suffers from intermarriage, and later in the same speech Rabbi Stav clarified that he believes that conversions should be based on the acceptance of the commandments.
