Rabbi of Crown Heights
As a member of the Crown Heights Beth Din (rabbinical court), Rabbi Osdoba is considered[by whom?] one of the community's chief rabbis (Aramaic, מרא דאתרא (Marah D'Asra)). The rabbinical court is the spiritual and religious body governing the Crown Heights Chabad community. There are currently four rabbis serving on the Beth Din:
- HaRav Avraham Osdoba
- HaRav Yosef Avraham haLevi Heller
- HaRav Aharon Yaakov Schwei
- HaRav Yosef Yeshaya Braun
Crown Heights Kashrus
Aside from the usual responsibilities of a community rabbi (officiate weddings etc.) Rabbi Osdoba also administers Crown Heights Kashrus (CHK, a kosher certification agency operating under the Crown Heights rabbinical court.
In recent years, Rabbi Osdoba's authority as sole administrator of the CHK was challenged by others, including supporters of Rabbis Schwei and Braun arguing that the arbitration panel (Zabl"a) ruled that the CHK should be run by a board of directors and is not a private entity, stating: "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.
