Smt. Sureshta Devi v. Om Prakash, (1991) 2 SCC 25, has concluded this issue and the view expressed in the said decision as of now holds the field.
9) In the case of Sureshta Devi (supra.), Supreme Court took the view: "
Under sub-section (2) the parties are required to make a joint motion not earlier than six months after the date of presentation of the petition and not later than 18 months after the said date. This motion enables the court to proceed with the case in order to satisfy itself about the genuineness of the averments in the petition and also to find out whether the consent was not obtained by force, fraud or undue influence. The court may make such inquiry as it thinks fit including the hearing or examination of the parties for the purpose of satisfying itself whether the averments in the petition are true. If the court is satisfied that the consent of parties was not obtained by force, fraud or undue influence and they have mutually agreed that the marriage should be dissolved, it must pass a decree of divorce." On the question of whether one of the parties may withdraw the consent at any time before the actual decree of divorce is passed, this Court held:
"13. From the analysis of the section, it will be apparent that the filing of the petition with mutual consent does not authorise the court to make a decree for divorce. There is a period of waiting from 6 to 18 months. This interregnum was obviously intended to give time and opportunity to the parties to reflect on their move and seek advice from relations and friends. In this transitional period one of the parties may have a second thought and change the mind not to proceed with the petition. The spouse may not be a party to the joint motion under sub-section (2). There is nothing in the section which prevents such course. The section does not provide that if there is a change of mind it should not be by one party alone, but by both. The High Courts of Bombay and Delhi have proceeded on the ground that the crucial time for giving mutual consent for divorce is the time of filing the petition and not the time when they subsequently move for divorce decree. This approach appears to be untenable. At the time of the petition by mutual consent, the parties are not unaware that their petition does not by itself snap marital ties. They know that they have to take a further step to snap marital ties. Sub-section (2) of Section 13-B is clear on this point. It provides that "on the motion of both the parties. ... if the petition is not withdrawn in the meantime, the court shall ... pass a decree of divorce ...". What is significant in this provision is that there should also be mutual consent when they move the court with a request to pass a decree of divorce. Secondly, the court shall be satisfied about the bona fides and the consent of the parties. If there is no mutual consent at the time of the enquiry, the court gets no jurisdiction to make a decree for divorce. If the view is otherwise, the court could make an enquiry and pass a divorce decree even at the instance of one of the parties and against the consent of the other. Such a decree cannot be regarded as decree by mutual consent."
