Sohn v. Calderon, 587 N.E.2d 807 (N.Y. 1991).Held that "Division of Housing and Community Renewal (DHCR) had exclusive original jurisdiction over owner's action for permission to demolish rent-controlled building, to evict his rent-controlled tenants, and to refrain from offering renewal leases to his rent-stabilization tenants, as well as over tenants' action to compel owner to make repairs necessary to render their units habitable; thus, Supreme Court had no concurrent authority over those matters."
