Can a court issue a verdict against someone based on a secretly recorded video?

Sharq newspaper wrote:

If someone is filmed secretly and this video is used as a document and evidence in court, what is the duty? Will this document not be valid because it was made without the person's permission?

In this regard, it should be noted that reasons in criminal proceedings have a method, that is, they are a way to create knowledge for the judge, so the judge may use any subject to reach knowledge, which may even be these images.

Of course, the judge must point out the factors that were effective in his opinion in his decision, and the Court of Appeals and the Criminal Prosecutor's Office monitor such decisions. And if they find that the issued vote is against the law, they will violate the vote and may even pursue the issuer of the vote.
