The 1980 Hague Convention is the main convention used when one parent believes that their children have been wrongfully taken (or wrongfully retained) by the other parent from their country of habitual residence. A number of defences are available under the convention and this article focuses on the defence of "consent".
This defence has been considered in both Scottish and English case law. In KT v JT 2004 SC 323, issues arose on where the onus of proof lies in consent cases and the nature of the consent required. It was held that consent has to be "real, positive and unequivocal" and the onus lies with the party raising the consent defence. In C v C 2003 SLT 793, the court considered the different approaches to be adopted when dealing with a consent defence rather than an acquiescence defence. Lord Macfadyen opined that "Acquiescence is concerned with the inference to be drawn, about the attitude of the party at the time of the removal, from his or her subsequent actings. Determining whether a party consented at the time of the removal does not normally involve such retrospective inference. It will usually, in my view, be sufficient to ask whether the evidence shows that, at the time of the removal, the party consented to it." In Re K (Abduction: Consent)  2 FLR 212, the court opined that the consent defence would still apply in a situation where the consenting parent later changes their mind after the removal has taken place.
The English Court of Appeal considered the consent defence in the case of In Re P-J (Children)(Abduction: Consent)  1 WLR 1237.
The general principles derived from In Re P-J are:
- Any consent given must be clear and unequivocal;
- Consent can be given for removal at a future but unspecified date but must still be in operation at that date;
- The defence must be viewed in the context of the realities of the family life, or more aptly the disintegration of the family life;
- It is not to be viewed in the context or governed by the law of contract;
- Consent can be withdrawn at any time before actual removal;
- The burden of proving consent rests on the person seeking to assert it;
- The question of consent is a factual matter.
The defence of consent became the main focus of a Scottish/Italian case where a non return order was issued at first instance which was then appealed to the Inner House. The appeal court issued their judgement on 1st October 2019 (YS v BS (2019) CSIH 50).
In brief, the parties have two boys and the Petitioner (dad) had raised proceedings against the Respondent (mum) for return of the children to Italy under the 1980 Hague Convention. "Consent" was evidenced by the factual circumstances of the case and particular with reference to a typewritten signed note from the Petitioner to the Respondent in September 2018 consenting to her relocating with the children to Scotland on their separation and follow up WhatsApp messages. The children relocated in January 2019. The Petitioner alleged that the signature on the note was not his and that in any event even if his "consent" was proven this was provided some months before the Respondent left with the children to go to Scotland. The Respondent argued he gave his consent to the relocation and that he did not revoke that consent until after she had relocated with the children. The judge granted a non return order.
The Respondent appealed to the Inner House and Lord Malcolm gave the judgement dismissing the appeal. He opined:
"It is well established that consent can be given to removal in the future. There was no material change of circumstances by January 2019, remaining characterised by marital volatility and disharmony. Prior to the removal there was no evidence of revocation of consent."
The Petitioner/Appellant is now seeking to appeal to the Supreme Court. The defence of consent may therefore remain in the spotlight.
