Legal Question in Civil Litigation in California

There is nowhere near enough information here to provide any answer.

If the plaintiff alleged fraud, then the judgment should contain a decision regarding the fraud claim -- yes or no. If there was no allegation of fraud, then the court should not be deciding that issue. You might take a look at the complaint and see what it claims. If the decision was within the very recent past and it included fraud when it should not, you might bring a motion for reconsideration or for new trial, especially since the judgment might be incorrect. If the judge refuses, then you have a very short time frame in which to file a notice of appeal.

Some context from the decision would help us provide you with a more specific answer.

The finding of fraud in civil suit does not necessarily mean criminal charges will be filed. (If that is what you were getting at.)
