Art. 3 SCA from 2019

Art. 3 Foundlings
1 A minor child of unknown parentage who is found in Switzerland acquires citizenship of the canton in which he or she was abandoned, and thus acquires Swiss citizenship.
2 The canton decides where the child holds communal citizenship.
3 Citizenship acquired in this way lapses if it is established who the parents of the child are, provided the child is still a minor and will not become stateless.
