MENNESSON v. FRANCE JUDGMENT 7 should not be overridden by the obligation to comply with a provision of the Convention. If the second alternative is retained on the grounds that international conventions must take precedence over public policy based on a standard provided for in a legislative provision, this will not necessarily result in the automatic collapse of the barriers erected by the domestic public-policy provision in such circumstances. As long as the European Court has not given a clear ruling on the question of the lawfulness of surrogacy and allows the States to legislate as they deem fit in this area, it can be considered contrary to public policy to validate, on grounds of respect for family life, situations created illegally within the countries which prohibit them. However, where it is merely a question of giving effect on the national territory to situations lawfully established abroad – be this at the cost of deliberately disregarding the strictures of a mandatory law – there is nothing to preclude international public policy – even based upon proximity – from being overridden in order to allow families to lead a life in conformity with the legal conditions in which they were created and the de facto conditions in which they now live. Furthermore, the best interests of the child, envisaged not only under the New York Convention but also under the case-law of the Court of Human Rights which has established this criterion as a component of respect for family life, also militate in favour of this interpretation. At least this is the lesson that I think we can draw from the judgment in Wagner [and J.M.W.L.] ...” 27. However, on 6 April 2011 the Court of Cassation (First Civil Division) gave judgment dismissing the appeal on the following grounds: “ ... the refusal to register the particulars of a birth certificate drawn up in execution of a foreign court decision, based on the incompatibility of that decision with French international public policy, is justified where that decision contains provisions which conflict with essential principles of French law. According to the current position under domestic law, it is contrary to the principle of inalienability of civil status – a fundamental principle of French law – to give effect, in terms of the legal parent-child relationship, to a surrogacy agreement, which, while it may be lawful in another country, is null and void on public-policy grounds under Articles 16-7 and 16-9 of the Civil Code. Accordingly, the Court of Appeal correctly held that, in giving effect to an agreement of this nature, the “American” judgment of 14 July 2000 conflicted with the French concept of international public policy, with the result that registration of the details of the birth certificates in question, which had been drawn up in application of that judgment, should be annulled. This does not deprive the children of the legal parent-child relationship recognised under Californian law and does not prevent them from living with Mr and Mrs Mennesson in France; nor does it infringe the children’s right to respect for their private and family life within the meaning of Article 8 of the Convention ..., or the principle that their best interests are paramount as laid down in Article 3 § 1 of the International Convention on the Rights of the Child ...” 4. Request for certificate of nationality 28. On 16 April 2013 the first applicant lodged an application with the Charenton-le-Pont District Court for a certificate of French nationality for the third and fourth applicants.
