Questão jurídica principal
Whether additional conditions, such as surrender of property or parental rights, could be attached to renunciation of Swiss citizenship.
Decisão extraída
No. The federal statute exhaustively lists the conditions for release from Swiss citizenship; extra conditions are inadmissible.
Fundamentação extraída
Art. 6 of the Federal Act of 3 June 1876 fixes the requirements exhaustively, so cantonal authorities may not add further burdens. Child-support and asset-retention questions belong before cantonal authorities, not as conditions for expatriation.
