Judgment: The mother applied under the Child Abduction and Custody Act 1985 (incorporating the Hague Convention 1980), and in the alternative under the inherent jurisdiction, for the return of her eight-year-old son to Russia. She contended that the father had wrongfully removed or retained the child in 2019. The father opposed the applications, raising issues of whether, at the relevant time, the child had been habitually resident in Russia and the mother had had rights of custody, whether the child would be at risk following a return, and whether the child objected to a return. The father's own prior applications, including for prohibited steps orders, had been stayed pending determination of the mother's applications. Cobb J found that the son had developed a sufficient degree of integration in life in Russia, while living there for ten months or so, to acquire habitual residence. The removal had indeed been in breach of the mother’s rights of custody. He did not believe that the son would be likely to suffer the “severe degree of psychological harm which the 1980 Hague Convention has in mind” (per Lord Donaldson) and the father therefore failed in his case under Article 13(b). Cobb J did not regard the son's objection to returning as being powerfully expressed or adamant. He reached the conclusion that a return to Russia was in the son's interests, where fully-informed welfare-based decisions could be made in a court to which both parents had ready access.
