Questione giuridica chiave
Whether the authority could change the payment mode and require personal collection of EL benefits after an extended foreign stay.
Decisione estratta
The authority could change the payment mode to postal payment with personal collection in Zurich; this was a lawful and proportionate way to verify residence and stay in Switzerland.
Motivazione estratta
Residence and presence in Switzerland are eligibility conditions for EL. The measure did not create an independently enforceable administrative burden but merely altered the method of disbursement; it still allowed temporary foreign stays of up to three months.
