Arbitrary denials of naturalization violate international law.

Naturalization Switzerland:
Foreign nationals may acquire Swiss citizenship if they meet the legal requirements for naturalization. Swiss citizenship can be acquired by descent, adoption or by ordinary or simplified naturalization. There are different naturalization procedures. There is ordinary and simplified naturalization, the re-naturalization of former Swiss citizens and the renunciation of citizenship.

Any person who has been wrongfully denied naturalization has the right to appeal the denial before an independent court. If a person feels that his or her right to a fair hearing, including the reasons for the decision to refuse naturalization has been impaired and that there has been a violation of the principle of prohibition of discrimination, the decisions of the migration authorities, the cantonal administrative courts and the Federal Administrative Court may be appealed to the Federal Supreme Court.
