Judgement for dismissal

Mere non appearance for few hearings cannot be a reason for dismissal 

If she continuosly absent, not interest the court may dismiss it.

S.K.Dharmesh vs. S.Mumtaz ([2023] 2 SCC 82) - The court reiterated that a DV complaint can be dismissed if the complainant's evidence is already recorded, their attendance is unnecessary, or if there's non-appearance or lack of interest.

It is general procedure that the court will dismiss the case if the prosecution do not show any interest in prosecuting the case despite given maximum opportunities.

In that situation you can rely upon your advocate and instruct him to put pressure on court.
