Babich & Sokur and Anor

In the Family Court of Australia, Mr. Babich (the applicant son) sought a declaration that the marriage between his mother, Mrs. Babich (the respondent wife), and Mr. Sokur (the respondent husband) was invalid. The wife, through her Case Guardian, also sought a decree of nullity. Both parties argued that the marriage was void because the wife lacked the mental capacity to understand the nature and effect of the marriage ceremony, rendering her consent unreal. The wife's Case Guardian also sought to introduce a ground of bigamy, alleging the husband was already married at the time of the ceremony, but this was refused by the Court due to the late stage of proceedings.

The central legal issue before the Court was whether the wife was mentally incapable of understanding the nature and effect of the marriage ceremony at the time of the marriage, thereby invalidating her consent. This required the Court to consider the wife's cognitive state, her understanding of the marriage contract, and the legal threshold for valid consent to marriage under Australian law. The Court also had to assess the credibility of the witnesses, particularly the husband and the son, and consider expert evidence regarding the wife's mental capacity.

Mullane J found that the wife was indeed mentally incapable of understanding the nature and effect of the marriage ceremony. This conclusion was heavily influenced by the expert opinion of Dr. P, a consultant psychiatrist, whose findings were preferred over those of Dr. B, a clinical neuropsychologist. Dr. P's assessment highlighted the wife's significant cognitive impairment, likely vascular dementia, compounded by grief, potential alcohol abuse, and untreated hypertension. The Court found that while the wife may have had a general understanding of marriage, she lacked the capacity to appreciate the specific implications of marrying the husband, particularly given his past behaviour and her own deteriorating mental state, including delusions and paranoia. The Court noted that the wife's consent was not real, as her decision-making capacity was severely compromised by her cognitive deficits.

Consequently, the Court declared the marriage solemnised between the husband and wife to be absolutely null and void and ordered the Registry Manager to issue a Decree of Nullity. The Court also listed the proceedings for a hearing concerning the applicant's application for the husband to pay the applicant's costs.
