Perjury is a criminal offense. You would need to convince your local District Attorney to bring charges. Remember, the only lies that count for purposes of proving perjury are those that were done under oath. Most proceedings under oath are written down, i.e., transcribed. Call the court to order the transcription. Then you can prove what they said, and prove it was a knowing lie.
