If you had filed the case but could not appear in the court on the date fixed for hearing then the case must have been dismissed due to your non-appearance. In this view of the matter your right to file another case of mutual divorce may now be foreclosed. You should consult your case personally with a lawyer and tell him all the details so that he may dispassionately ascertain if divorce can be applied for again and on what grounds.
There is no specific law in this regard. The only way a marriage can be brought to an end is through the process of court.
