Passing of the decree in S. 25 meant the passing of a decree of Divorce, Nulity, Restitution of Conjugal Rights or Judicaial Separation and not the passing of a decree dismissing the petiton.If the petition fails then no decree is passed, i.e, the decree is denied to the applicant and therefore alimony cannot be granted in a case where a decree is refused because in such a case the marriage subsists.
