Kernrechtsfrage
Whether the one-year period under Art. 12(2) Hague Convention was established for proving settlement in the new environment.
Extrahierter Entscheid
The one-year period is counted from the initial wrongful retention/removal, not from the later move to Switzerland; however, given the abusive evasion of the prior return order, the settlement proof was subject to particularly strict requirements and was not established.
Extrahierte Begründung
The wording of Art. 12 in conjunction with Art. 3 points to the first wrongful retention. The mother's move to Switzerland to evade an enforceable return judgment was an obvious abuse of rights, which required a stringent assessment of integration evidence. The records showed repeated moves and only weak, party-driven reports; the children had not shown roots in the new environment.
