Questione giuridica chiave
Whether the Thurgau district court judgment on paternity also bound St. Gallen authorities on the child's municipal citizenship status under Art. 61 BV.
Decisione estratta
The Thurgau court lacked competence to decide the child's citizenship status for St. Gallen; therefore its judgment had no res judicata effect against Kirchberg or St. Gallen.
Motivazione estratta
Art. 61 BV requires enforcement only of final civil judgments rendered by a competent court. For the question whether an out-of-wedlock or betrothed child acquires the father's home municipality, only the law and courts to which that municipality is subject are competent. Since St. Gallen law gave the child the mother's status, the foreign-cantonal judgment could not confer the father's citizenship.
