The course of practice here and in England warrants the statement that it is now no longer correct that a strong affirmative case is necessary negativing the conditional prohibition of the statutory provision. The statute is now regarded as investing the courts with authority to form a discretionary judgment whether the marriage should be dissolved, forming that judgment upon the circumstances of each given case, not neglecting but weighing the considerations which, according to the case law, are always material. Indeed it is so far from correct to demand a strong affirmative case that current English text books state the rule of practice to be almost the opposite. Thus in Rayden on Divorce, 4th ed. (1942), at page 149) it is said: " from about 1917 the exercise of that discretion became increasingly less stringent, the general view adopted being that where a marriage has completely broken down it is prima facie in the interest of the community that the marriage should be dissolved, and now it is scarcely inaccurate to say that the discretion is usually exercised in favour of a petitioner who has committed adultery, regardless of its duration or character or promiscuous nature, unless there are grounds for holding that the grant of a decree would be contrary to the interests of the community, or there has been culpable delay, or there has been perjury and deception by the petitioner, or conduct by him or her conducing to the adultery of the other spouse." Mr. Tolstoy's recent book on the Law and Practice of Divorce and Matrimonial Causes at p. 59 goes even further: - "Generally speaking, the Court will exercise its discretion in favour of the petitioner who is himself guilty of adultery unless there are circumstances justifying its refusal, which happens comparatively rarely." The list of considerations which a court must take into account has now been settled by the House of Lords. In Blunt v. Blunt [1] , Lord Simon, in whose opinion the other Lords concurred, speaks of four considerations or circumstances which Lord Merrivale had mentioned in Wilson v. Wilson [2] as warranting the exercise of the judicial discretion in the petitioner's favour. Lord Simon proceeds: - "These four points are: (a) the position and interest of any children of the marriage; (b) the interest of the party with whom the petitioner has been guilty of misconduct, with special regard to the prospect of their future marriage; (c) the question whether, if the marriage is not dissolved, there is a prospect of reconciliation between husband and wife; and (d) the interest of the petitioner, and, in particular, the interest that the petitioner should be able to remarry and live respectably. To these four considerations I would add a fifth of a more general character, which must, indeed, be regarded as of primary importance, namely, the interest of the community at large, to be judged by maintaining a true balance between respect for the binding sanctity of marriage and the social considerations which make it contrary to public policy to insist on the maintenance of a union which has utterly broken down. It is noteworthy that in recent years this last consideration has operated to induce the court to exercise a favourable discretion in many instances where in an earlier time a decree would certainly have been refused."
