Questione giuridica chiave
Whether the constitutional appeal against the cantonal return order was admissible
Decisione estratta
The appeal could not be entered into because the complaints were insufficiently reasoned and relied on inadmissible new allegations.
Motivazione estratta
The appellant failed to engage with the cantonal reasoning on Article 13 Hague Convention and relied on factual claims not raised below; the Federal Supreme Court therefore could not examine the constitutional and Convention complaints.
