Dr. N.G. Dastane vs Mrs. S. Dastane on 19 March, 1975
In Dastane (supra) the Apex Court observed that in case of the allegation of mental cruelty the inquiry must begin as to the nature of the cruel treatment and then as to the impact of such treatment in the mind of the spouses. Whether it caused reasonable apprehension that it will be harmful or injuries to live with the other, ultimately is matter of inference to be drawn by taking into account the nature of the conduct and its effect on the complaining spouse. In the present case, the conduct of the wife, as alleged, that she was averse to cohabitation can be said to be per se unlawful as it is the legal duty of every spouse to willingly participate in cohabitation, which has been held to be the foundation of every marriage.
