Key legal question
Whether the children should be placed under the mother's sole custody instead of joint parental authority.
Extracted holding
The request for sole custody was unfounded; joint parental authority remained in force.
Extracted reasoning
A sole-award of parental authority is only an exceptional measure requiring a serious, chronic conflict that harms the child. The appellant did not show a child-welfare risk, and the alleged conduct of the father did not justify departing from the statutory rule of joint parental authority.
