M v F

The appeal concerned a mother who brought her six-month-old child to Australia from Belgium without the father's knowledge or consent. The trial judge had found that the child faced a grave risk of psychological harm or an intolerable situation upon return to Belgium due to the mother's psychological state and potential impoverishment. To mitigate this risk, the trial judge initially considered imposing various conditions, including visa arrangements, a protection order for the mother, and financial support. These conditions were later varied to a written undertaking from the father in lieu of a court-ordered protection order.

The central legal issues before the appellate court were whether the conditions imposed by the trial judge were sufficient to alleviate the grave risk to the child upon return to Belgium, and if not, what was the proper exercise of discretion in such circumstances. The court was required to determine the criteria for imposing conditions under the Hague Convention in cases where a grave risk exception to return is established.

The appellate court held that any conditions imposed to mitigate a grave risk to a child upon return must be clearly defined and objectively measurable to ascertain their fulfilment. The court found that the conditions as formulated by the trial judge did not meet these requirements and failed to neutralise the risk to the child. Given the significant difficulties in establishing satisfactory preconditions for the child's return, the court concluded that the only proper exercise of discretion, once the grave risk exception was established, was to refuse a return order. Consequently, the appeal was allowed, and the order for the child's return was discharged.
