‘If there is one question better settled than any other in international law, it is that as regards marriage – putting aside the question of capacity – locus regitactum. If a marriage is good by the laws of the country where it is effected, it is good all over the world … If the so-called marriage is no marriage in the place where it is celebrated, there is no marriage anywhere …’
“The answer to the question of whether a person is recognized by the state as being validly married should be capable of being easily ascertained. Certainty as to the existence of a marriage is in the interests of the parties to a ceremony and of the state. Indeed, it could be said that the main purpose of the regulatory framework (summarised below), since it was first established over 250 years ago, has been to make this easily ascertainable, and, thereby, to provide certainty”
“No declaration may be made by any court, whether under this part or otherwise – a. That a marriage was at its inception void…”
“[60] I acknowledge of course, as I have to, that, as a matter of English domestic law, section 12(c) of the 1973 Act renders the marriage between IC and JK voidable rather than void. It does not, however, in my judgment follow that the English courts are bound to recognise the marriage as valid. To put the matter another way, the status conferred by sections 12 and 16 of the 1973 Act on the marriage is in no sense inconsistent with the High Court’s capacity to refuse it recognition”
“There is abundant authority that an English court will decline to recognize or apply what would otherwise be the appropriate foreign rule of law when to do so would be against English public policy; although the court will be even slower to invoke public policy in the field of conflict of laws than when a purely municipal legal issue is involved.”
‘It is clear that if, under the relevant proper law, the effect of the defect is to cause the marriage to be valid or to be invalid, the lex fori cannot alter this effect (save possibly in circumstances not relevant in this case). However, I do not consider that the English court is bound solely by the foreign law's classification of the defect and, in particular, the effect of that classification if it goes beyond deciding that the marriage is either valid or invalid. …… the foreign law might adopt the same or might adopt very different classifications to that adopted by English law. There might be no sub-division into void, voidable and non-marriage. There might be different ways of expressing the same or similar concepts.’
