Judgment: The father applied under the 1980 Hague Convention for the return of his three-year-old son to Australia. The mother resisted the application on the grounds of habitual residence in England, acquiescence, and a grave risk of physical or psychological harm to the child, or his being in an otherwise intolerable situation, if the court required his return to Australia. Theis J decided that the defence on acquiescence would not have succeeded, but the mother had established that the protective measures put in place would not have been sufficient to reduce the risk to a level that fell below the Article 13(b) threshold. Either way, Theis J had already reached the conclusion that the son's habitual residence at the relevant time had been in this jurisdiction, and thus there had been no breach of Article 3 of the Hague Convention. The father's application was dismissed.
