Legal Question in Civil Litigation in California

Yes. Only the DA.

There is no civil cause of action for perjury. But depending upon the circumstances, the perjured statements may serve as the basis for a claim of defamation, intentional infliction of emotional distress, or perhaps other causes of action.

Bear in mind that you generally cannot successfully sue someone for statements made in the course of a governmental or court proceeding. Most perjury occurs in these contexts.

You should discuss the specifics of your case with a lawyer in your area to see whether you have a viable case.

I agree with Mr. Hoffman, in that there is no civil cause of action for perjury.
