Key legal question
Whether unlawful stay was justified by the unwritten ground of protecting legitimate interests because of paternity and contact with the child.
Extracted holding
The justification ground did not apply because remaining in Switzerland was not the only reasonable way to recognize paternity or maintain contact; a temporary departure was a feasible alternative.
Extracted reasoning
The court held that the appellant had not shown that permanent presence in Switzerland was necessary and proportionate, since paternity recognition and contact rights could also be pursued from abroad or after a temporary return to the home country.
