“A wife can defend herself against a suit for the restitution of conjugal rights, at her husband's instance, on the grounds of adultery or cruelty only . The Ecclesiastical Court will recognise no other cause, whether by agreement or otherwise, as justifying separation.
“We are of opinion, that a wife may perhaps defend herself in such a suit on the ground of adultery, without praying for a divorce ; but it is not a course likely to be resorted to; and we are not aware of any case in which it has been done.
“Assuming that the wife could have established adultery without praying for a divorce, the judgment would probably have merely dismissed her from the suit, and pronounced against the prayer of the husband; but we believe no such case has occurred, nor is such a case likely to arise.” [See the Second Series, where the opinion is given at length.]
