Require quick help in dv evidences

My friend wife filed DV case around four year back. After two year, she filed evidences. Her interim maintenance rejected by Mumbai high court. High court mentioned in order that petitioner is unable to prove in her petitioner that she is victim of DV and she is earning 70k hence her interim maintenance rejected. But in said order, high court said to file cogent evidence to proceed case. Now we observed that her evidence are not sufficient as it's just contain mail and nothing. Please advice me what should i do?.. may i go discharge the respondents or should file reply to evidence to dismiss case as it's not proving from her evidences as she is victim of DV?.. Please help me...
