Member of the Crown Heights Beis Din
Rabbi Aharon Yaakov Schwei's Rulings on Carrying in Crown Heights
Rabbi Aharon Yaakov Schwei joined Rabbi Yosef Yeshaya Braun in the first public Beis Din ruling on the proposed Crown Heights eruv. He also signed the subsequent letters affirming the authority of the neighborhood Rabbonim over a public eruv.
Carrying is absolutely forbidden
The ruling he signed on 2 Iyar 5776 leaves no practical uncertainty: “It is absolutely forbidden to carry on Shabbos in the streets of Crown Heights.” It adds that the structure then being advertised was to be treated as nonexistent.
The ruling was issued as a public instruction, not a theoretical discussion of whether individual components of the route might be repaired. Until a valid eruv was established under the proper halachic authority, residents were to observe Shabbos as before and not carry.
His position remained part of the local psak
After Rabbi Schwei's passing, the later Beis Din notice named him together with the other Crown Heights Rabbonim who had categorically rejected the eruv. The notice did not announce a new standard; it repeated the same prohibition already stated in his signed ruling.
His part in the Crown Heights record is therefore direct: he signed the first public prohibition and the letters establishing the Beis Din's responsibility for the neighborhood.
