Joint parental authority revoked and sole custody granted to mother due to father's failure to cooperate.

The court revoked joint parental authority and granted sole custody to the mother while ordering the father to pay child support. The mother argued the father was unfit due to his refusal to participate in the child's life, whereas the father claimed he was merely busy with work. The court ruled that the father's persistent non-cooperation and lack of contact constituted a breach of his duties, necessitating a change in custody arrangements to protect the child's best interests.
