 * Rabbi Yosef Braun

Crown Heights Kashrus
Rabbi Schwei was involved in supervising and granting kosher certification under the Crown Heights rabbinical court. In recent years, Rabbi Osdoba's authority as sole administrator of the CHK was challenged by others in the community, including supporters of Rabbi Schwei and Rabbi Braun arguing that the arbitration panel (Zabl"a) ruled that it should be run by a board of directors "There is a need to create a new Vaad HaKashrus, which shall be the executive body of the Rabbis and the Vaad Hakohol. The court however remanded this ruling back to the arbitration panel for clarification  which is yet to reconvene

Statement on local blogs
Both Rabbis Osdoba and Schwei spoke out against several "hate blogs" created by members of the community.

Banning of Call of the Shofar
