Joint parental authority and residence revoked due to one parent's failure to fulfill duties and endangering the children's best interests.

The court dismissed the application to revoke joint parental authority and residence for two children. The applicant argued that the other parent failed to fulfill duties and endangered the children's well-being, while the respondent maintained their right to parental authority. The court found no sufficient evidence to prove the alleged endangerment or failure, thus upholding the existing arrangement.
