Key legal question
Whether the cantonal court violated due process by not admitting the father's request for custody transfer as a procedural amendment.
Extracted holding
No due process violation arose from the formal non-entry, because the court nevertheless reviewed custody on the merits and effectively confirmed the first-instance allocation.
Extracted reasoning
The non-entry decision was based on inadmissible claim amendment, but the custody question was examined ex officio. If the custody allocation were unlawful, the non-entry ruling would fall with it.
