Security detention continuation: lack of supplementary grounds under § 71 FamFG

The German Federal Court of Justice (BGH) 13th Civil Senate dismissed the legal appeal (Rechtsbeschwerde) of the guardian ad litem, leaving the lower court's decision upholding the security detention of the affected person in force. The dispute concerned a challenge against the continued execution of ordered security detention within guardianship proceedings, where the appellant failed to submit any supplementary submissions or demonstrate circumstances within the statutory deadline under § 71 (2) FamFG that would warrant a different assessment by the appellate court. Relying on the doctrine of procedural default and the principle of no further reasoning where no new arguments are presented, the court applied § 74 (7) FamFG to reject the appeal without a detailed written justification, as the factual and legal landscape had not changed since the prior rejection of the suspension of enforcement.
