To get an order of maintenance dismissed, an appeal against the order under Section 125 of the Code of Criminal Procedure, 1973 is not maintainable. The legal option which is available is to go for the revision proceedings against the order under Section 397 of the Code of Criminal Procedure, 1973.
However, in your case, even revision proceedings also seems to be impossible as there is an apparent delay of 9 years whereas revision against the maintenance order should have been filed within 90 days from the decree or order passed.
Even if you are able to convince and satisfy the court about this inordinate delay, the court may or may not allow your revision application. It may be assumed that you’ll be taking the ground that your wife has deserted you and left the matrimonial home without any sufficient reason only to extort maintenance from you, even when she has sufficient means to maintain herself.
So, in that case, Masud Ahmed vs. State of Bihar [2019 SCC OnLine Pat 1880] and Aarif vs. Shajida [2019 SCC OnLine MP 1379] could be of help to you as in these case laws, the Courts have approved the revision application of the husbands because the wives could maintain themselves.
But let me tell you, numerous judgments have also been passed by the court holding that even if the wife is capable of earning or is earning, cannot be denied the maintenance by the husband. So, there is no hard and fast rule which the courts have been following in allowing or rejecting the revision application, it all depends on the facts and circumstances of each case.
Hope this satisfies your query! All the best!
