You've got a lawyer, so you should ask them if it's possible to get your fees and costs from the unsuccessful party.
If the case was dismissed, it's not "open," and you have no need to bother with the audio, the video, and the lies. Your lawyer apparently didn't need your evidence to get the case dismissed, since the party bringing the claims is the one with the burden of proof, which apparently they didn't meet.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
Just because you won doesn't entitle you to attorney fees. Many times in civil cases because the party is not granted a civil restraining order doesn't mean the judge thinks the respondent/defendant acted properly or should be granted relief. It is not common they make an award of attorney fees for either party except in extreme cases. Also many "lies" are trivial and in California unauthorized recordings is subject to be excluded and can be punished by a $5000 fine.
This is just my opinion and not a comprehensive answer. You assume the risk because this answer may not apply to your situation depending on the facts.
