On the face of it, it sounds to be reasonable. But, when a spouse (suppose husband) files Section 9 RCR, his thrust in the body of the petition would be that the wife deserted him without having any reasonable cause. Then, it would be difficult for him to seek either divorce or judicial separation on the ground of cruelty or any other ground available under Section 13 or 10 of the Act. Because, the grounds under Section 13 and 10 are contra to the grounds under Section 9 of RCR. Suppose, in his RCR petition he alleges a number of cruel acts perpetrated by his wife and alleges that she left without having any reason and he is willing to take her back, it amounts to condonation of cruel acts and hence on that reason also, he will not be entitled to divorce or judicial separation. As such, such alternative prayer is not possible if you combine Restitution prayer with divorce/judicial separation prayer.
