Questione giuridica chiave
Whether supplementary benefits began in August 2016 with the IV application or only in June 2017 with the EL application.
Decisione estratta
The EL entitlement began only in the month of the EL application; the IV application could not be treated as an EL application.
Motivazione estratta
The statute provides retroactive start dates only in specific cases, none of which applied. The court found no planwidriges silence warranting analogy, no duty to forward the IV claim as an EL claim because the IV office was competent for the IV request, and the duty to inform under Art. 27(3) ATSG was satisfied by the later notice in the IV decision.
