Decisão extraída
The father's custody and parental authority were upheld; the mother's request was rejected.

The cantonal courts reasonably relied on the father's adequate parenting capacity, a more stable environment for the child, and the mother's insufficient parenting capacity. The Federal Court found no misuse of discretion.
