Williams v Williams (Divorce: Cruelty)

Insanity is not, by itself, a defence to a petition for divorce founded on cruelty. The court must decide objectively, after considering the whole matrimonial relationship, whether the respondent’s conduct was sufficiently grave to amount to cruelty. Mental illness remains a relevant circumstance and appropriate allowance must be made for its effects.

The M’Naghten Rules do not govern matrimonial cruelty. In particular, a respondent who knows the nature and quality of the conduct cannot defeat the petition merely because mental disease prevented an understanding that the conduct was wrong. Neither an intention to injure nor moral blameworthiness is an essential ingredient of cruelty, although intention and mental condition may affect how equivocal or borderline conduct is characterised.

The respondent husband suffered from incurable mental illness and auditory delusions. Believing his wife to be persistently adulterous, he repeatedly accused and followed her. The conduct was found to have injured her health. He knew what he was doing but, because of his delusions, believed that his accusations were justified.

The Commissioner considered himself bound by authority to apply both limbs of the M’Naghten Rules and dismissed the wife’s petition. The Court of Appeal, by a majority, dismissed her appeal, applying Palmer v Palmer [1955] P 4. The wife appealed to the House of Lords.

The central questions were whether insanity could prevent conduct from constituting matrimonial cruelty and whether either limb of the M’Naghten Rules governed that inquiry.

1. Appeal allowed by a majority of three to two. Lord Reid, Lord Evershed and Lord Pearce concluded that the husband’s inability, through insanity, to appreciate that his accusations were wrong did not answer the wife’s petition. The case was disposed of on the Commissioner’s unchallenged findings concerning the character and effect of the conduct.

2. Per Lord Reid, Lord Evershed and Lord Pearce, the M’Naghten Rules were devised for criminal responsibility and do not govern matrimonial cruelty. Their rigid application would produce arbitrary distinctions between forms of mental illness. The criminal-law meaning of “wrong” adopted in Reg v Windle [1952] 2 QB 826 was particularly unsuitable for divorce proceedings.

3. Per Lord Reid, cruelty does not require malignity, an intention to injure or a minimum degree of culpability. The court must assess the character and gravity of the acts after making allowance for the parties’ disabilities and temperaments. An insane respondent is governed by the same approach as a respondent whose capacities are abnormal but fall short of insanity.

4. Per Lord Evershed, with Lord Pearce reaching substantially the same result, insanity is a relevant circumstance but is not necessarily an answer. The inquiry remains objective: in all the circumstances, did the respondent treat the petitioner with cruelty? Where the respondent knew the nature and quality of the conduct, it was no answer that delusions prevented recognition that it was wrong.

5. Per Lord Pearce, insanity may negate an intention needed to turn otherwise equivocal conduct into cruelty. It does not bar relief where the conduct is sufficiently grave to constitute cruelty irrespective of motive or intention.

6. Lord Morris and Lord Hodson dissented. They considered mental disease capable of preventing conduct from being cruelty where the conduct resulted from a disordered mind and the respondent lacked rational responsibility or moral judgment. Both would have dismissed the appeal, although neither regarded the M’Naghten Rules as an inflexible code for matrimonial cases.

1. House of Lords: Allowed the wife’s appeal by a majority of three to two and displaced the ruling that the second limb of the M’Naghten Rules defeated the petition.

2. Court of Appeal: Willmer and Davies LJJ, Donovan LJ dissenting, dismissed the wife’s appeal: [1962] 2 WLR 977. The majority considered itself bound by Palmer v Palmer [1955] P 4 to apply both limbs of the M’Naghten Rules.

3. Commissioner: The Commissioner found that the husband knew what he was doing but, through insanity, did not know that it was wrong. Although the conduct had injured the wife’s health, he considered himself bound by authority to dismiss her petition.
