In the County Social Services Agency's appeal from a juvenile court's order denying the agency's motion to terminate the de facto parent status of respondent, and granting the application of respondent's partner for de facto parent status, the order is affirmed where: 1) the juvenile court had the authority to determine that respondent's conduct constituted serious physical abuse, but conclude that the single incident of misconduct found to have occurred did not rise to the level warranting termination of his de facto parent status; and 2) the juvenile court did not abuse its discretion in denying the motion to terminate respondent-s de facto parent status.
