If a husband is discharged in 498A and 406 cases due to insufficient evidence, it's possible to appeal orders made under Section 125 and the DV Act, even if the girl's statements differ across cases. While acquittal in a criminal case doesn't automatically mean no maintenance is due, contradictory statements can be used in further appeals. If the appeal period for the criminal case has passed, a suit for malicious prosecution might be an option. It's crucial to consult a local lawyer to assess the specific facts and documents for the best course of action.
