“No declaration may be made by any court, whether under this Part or otherwise— (a) that a marriage was at its inception void.”
“So in my view the Court must be able, in the rare cases where such a point arises, to rule that some questionable ceremony or event, whilst having the trappings of marriage, failed fundamentally to effect one, such that it neither needs nor is susceptible to a decree of nullity to determine its lack of any legal status: ie to find in convenient shorthand that it is a ‘non-marriage’ or a ‘non-existent marriage’.”
