Key legal question
Whether the Federal Supreme Court could review the custody reallocation and whether the cantonal court exceeded its review powers under procedural law.
Extracted holding
The complaint failed; in child matters the court had to consider new circumstances, so the cantonal court was not limited to reviewing only abuse of discretion.
Extracted reasoning
Federal law requires the child welfare inquiry to be based on current circumstances and mandates official investigation and consideration of new facts; incompatible cantonal limits yield to federal law.
