"...the principles applicable to the disposal of this application are: (i) The power to impound a passport pending the disposal of a financial remedy claim exists in principle in aid of all the court's procedures leading to the disposal of the proceedings. (ii) But it involves a restriction of a subject's liberty and so should be exercised with caution. The authorities emphasise the short-term nature of the restraint. The law favours liberty. (iii) A good cause of action for a substantive award must be established. (iv) The Applicant must establish that there is probable cause for believing that the Respondent is about to quit the jurisdiction unless he is restrained. (v) The Applicant must further establish that the absence of the Respondent from the jurisdiction will materially prejudice her in the prosecution of her action. (vi) Provided that the principles in (i) – (v) are carefully observed a passport impounding order will represent a proportionate public policy based restraint on freedom of movement founded on the personal conduct of the Respondent."
"It is possible to restrain a party from leaving the jurisdiction and to make a consequential order for the surrender of his or her passport. The jurisdiction exists where the other party has established a right to interlocutory relief, such as an Anton Piller order, which would otherwise be rendered nugatory. It exists where a hearing is shortly to take place, the efficacy of which would be frustrated by his absence. In my view it exists in principle in aid of all the court's procedures leading to the disposal of the proceedings. I consider that the jurisdiction is also available in some circumstances after judgment. To be specific, it can be invoked to aid the court's established procedures for enforcement of the judgment."
"Like freezing orders, passport orders can be made post judgment to aid the court's enforcement procedures. I note that if there is a substantive award to enforce, Mostyn J's principle (iii) falls away. As for his principle (v) it must be read as requiring the applicant to establish that the applicant's ability to enforce the Judgment through the Court's established procedures will be materially prejudiced by the respondent's absence from the jurisdiction."
