My complaint was rejected by the court because they felt there wasn’t enough evidence to proceed. Should I file a criminal case or a civil suit to seek justice? I have documents proving the complaint was false, do I still need witnesses?

In India, filing a criminal case or a civil suit depends on the nature of the complaint and the relief sought. Since your complaint was rejected for lack of evidence, gathering stronger evidence is crucial. You can consider filing a civil suit with the documents proving the falsity of the complaint, but witnesses are still recommended for a stronger case.
