"There should in my view be a full investigation before myself or a judge of this court where, if necessary, following a fact finding exercise and a decision, the matter could be re-argued in the event of both parties being guilty of wilfully and knowingly entering into a bigamous marriage."
"Her counsel accepted the proposition of law as put forward by Mr Wagstaffe, that if the wife had the knowledge alleged, then the financial relief application of the husband should not be struck out."
"Mr Wagstaffe seeks to distinguish the case of Whiston , saying that there has been no deceit of an innocent party involved, because there was full knowledge on the part of the wife. This is a submission which counsel conceded without argument. Her submissions to me on behalf of the wife were based entirely on the facts and the findings of fact which the court should make and on credibility and not on the law. I have therefore not had what I would regard as full argument on this point."
"There is much authority on the circumstances in which the courts will refuse to enforce contractual rights upon grounds of public policy, but I doubt whether this is directly applicable where the right is conferred and the concomitant duty is imposed by statute."
"The fact that there is no specific mention in the act of disentitlement so far as the widow is concerned if she were to commit this sort of offence and so become a widow is merely an indication, as I see it, that the draftsman realised perfectly well that he was drawing this act against the background of the law as it stood at the time."
"I would respectfully agree with that dictum and I would agree that in each case it is not the label which the law applies to the crime which has been committed but the nature of the crime itself which in the end will dictate whether public policy demands the court to drive the applicant from the seat of justice. Where that line is to be drawn may be a difficult matter to decide, but what this court has to determine is whether in the present case what this applicant did was sufficient to disentitle her to her remedy."
"Where the criminal act undermines our fundamental notions of monogamous marriage I would be slow to allow a bigamist then to assert a claim, an entitlement at which she only arrives by reason of her offending. It is obviously proper that the Act of 1973 should afford the innocent party to a bigamous marriage relief. Where an applicant entered into another 'marriage' genuinely and reasonably believing he or she was free to do so, and was therefore innocent of the crime of bigamy, that person too may have an entitlement, though that is not the matter for us to consider today. Today we have this respondent seeking to profit from the crime. Her claim derives from the crime. Without her having entered into this bigamous ceremony she would not have got to the judgment seat at all. She should now, in my judgment, be prevented from going any further."
"This case falls squarely within the principle that as a matter of policy the court will not lend its aid to one who, to succeed, must found her claim on a criminal offence of sufficient gravity, as this crime of bigamy in my judgment was."
"Bigamy is a crime which, of course, involves mens rea. There is no such person as an innocent bigamist. Bigamy, as opposed to mere cohabitation, strikes at the very heart of the institution of marriage. In these circumstances, the fact that this respondent has contracted a bigamous marriage would be a necessary foundation for her claim for financial relief under theMatrimonial Causes Act 1973 . For a litigant to have to rely upon his or her criminal behaviour in order to get a claim on its feet is, in my judgment, offensive to the public conscience and contrary to public policy."
"I would seek to explain my approach as follows. (1) In all the relevant sections of the Act of 1973 dealing with ancillary relief all decrees of nullity appear to be treated in the same way. (2) Section 25 of the Act of 1973 requires the court when exercising its powers under section 23 or 24 to take account of all the circumstances of the case. This requirement suggests that the scope for the trial of a preliminary issue is very limited. (3) The principle of public policy which can be invoked to bar a claim depends on the establishment of a 'serious' crime by the claimant. In many cases, as it seems to me, a decision as to whether or not a particular crime has crossed the threshold of seriousness may involve an investigation of all the circumstances, including the effect on the other party and any mitigating factors which may reduce the degree of blame. In a case concerning a transsexual in particular such an investigation may require detailed consideration of the medical treatment and advice which the applicant received over a period. (4) I have not been persuaded that in a case which involves the exercise of the court's discretion it is necessary or desirable to carry out a preliminary inquiry to determine one aspect of an applicant's conduct before the general merits of the claim are investigated. As I have already indicated, crimes may vary to an almost infinite degree in their seriousness. This is particularly true of offences under thePerjury Act 1911 . (5) Though it is clear from the decision of the House of Lords in Tinsley v Milligan[1994] 1 AC 340 that where considerations of public policy intervene to prevent the enforcement of rights claimed under an illegal contract the court is precluded from carrying out a balancing operation, the situation appears to me to be different where parliament itself has conferred a discretion on the court and has included a requirement that the court in exercising that discretion should consider all the circumstances of the case. For these reasons I would not decide the preliminary issue on the basis that the applicant is barred in limine from pursuing the claim because by signing the false declarations he had committed a serious crime. Nor would I bar him by the invocation of the wider doctrine of ex turpi causa without investigating all the circumstances of the case."
