Questão jurídica principal
Whether the respondent's later withdrawal of the reimbursement request could invalidate the already paid AHV contribution reimbursement.
Decisão extraída
The withdrawal had no legal effect because the respondent still had foreign residence when the reimbursement was granted and the later intention to return to Switzerland did not re-establish Swiss residence.
Fundamentação extraída
A mere declaration of intent to return does not create residence under Art. 24(1) ZGB. At the relevant times the respondent lived abroad, and reimbursement was therefore lawful. A withdrawal made in view of future AHV pension entitlement cannot undo that result.
