Facebook has been sued for contempt of court for refusing to listen to police users, but the charge has been vetoed by the trial judge. Some civil rights organizations have asked for the publication of legal opinions on the case. But on Wednesday, the request was rejected by the federal court of appeal. A jury of three judges from the Ninth Circuit Court of appeal rejected the claims of organizations such as the ACLU and the Electronic Frontier Foundation.

these civil liberties organizations believe that although monitoring is usually conducted in secret, the relevant judicial decisions are almost always open. Technology companies urgently need to know how far the federal government can go to ask them to monitor users, they said.

although this issue has not yet come into public view, some media have begun to focus on whether the wiretap act can be used to monitor end-to-end encrypted voice calls in Facebook messenger. Under the wiretap act, police departments can ask phone companies to help monitor users’ calls.

because Facebook refused to listen in this regard, the prosecution demanded that Facebook be convicted of contempt of court, but the trial judge refused. The judge said he would not disclose the reasons for his refusal, and the court of appeal upheld the judge’s decision on Wednesday.

the U.S. Department of justice hopes to keep relevant judicial decision documents confidential, believing that the disclosure of such documents may harm some ongoing criminal investigations.
