The binding legal principles established are: (1) Section 62 of the Children's Act 38 of 2005 permits children's courts to order factual investigations into the circumstances of children and relevant persons, but does not permit the court to delegate its statutory function of assessing and consolidating expert reports to third parties - such an order is made without jurisdiction and is a nullity; (2) Section 62 only permits the appointment of natural persons with relevant expertise or suitable qualifications, not legal persons or organizations - an order appointing an organization is a nullity for lack of jurisdiction; (3) In relocation applications, courts must show deference to the reasonable and bona fide decisions of custodian parents because: (a) the custodian parent bears primary responsibility for raising the child, (b) thwarting the custodian parent's exercise of fundamental rights to dignity, privacy and freedom of movement negatively impacts the parent's emotional and psychological wellbeing, which directly affects the child's welfare, and (c) a frustrated and bitter parent cannot provide the happy and secure environment a child needs; (4) The best interests of the child standard is paramount but must be assessed holistically, not narrowly, taking into account the wellbeing of the custodian parent and the impact of parental conflict on the child.
