Legal Question in Criminal Law in California

I don't know what you mean by "delivering an accusation" however I think the best advice in any case is to get an attorney if you are being investigated or have already been charged criminally.

As far as you filing a suit for harassment against someone else, that is a civil issue and would be undertaken (if at all) after the criminal case is resolved.

If you're saying you are being charged in retribution for filing a civil case, the same applies - get a good criminal defense attorney who regularly practices in the court where your case will be heard.

It's not likely the DA is filing a case against you because you filed a civil suit. If charges are filed, they have evidence against you, or believe they do anyway. Good luck!
