AD v State of New South Wales

The applicant, AD, appealed to the Court of Appeal of New South Wales against a judgment of the District Court concerning claims of false imprisonment, trespass, and misfeasance in public office. The dispute arose from AD's arrest and the subsequent transfer of care of children, which AD alleged was contrary to Family Court orders and inconsistent with federal law.

The Court of Appeal was required to determine whether AD's arrest was lawful, specifically whether the arresting officer had reasonable grounds for suspicion and whether the arrest was reasonably necessary. Further issues included whether the transfer of the children was unlawful and whether the actions of the police officer constituted misfeasance in public office, requiring proof of malice and a causative link between the officer's conduct and AD's loss. The court also considered the potential inconsistency between state police actions and federal Family Court orders.

The Court of Appeal granted AD leave to appeal, but only in relation to the claim of false imprisonment. Ultimately, the appeal was dismissed. The court upheld the District Court's decision, finding that the arrest was lawful and that the subsequent actions did not give rise to a successful claim for false imprisonment or misfeasance in public office. A non-publication order was continued, and AD was ordered to pay the costs of the State of New South Wales.
