Don judges review subpoenas before they are sent to ISPs?
No. The issuing of civil subpoenas is not monitored by the court handling the case. Under the normal rules of discovery in civil lawsuits, parties to a suit can simply send a subpoena to anyone they believe has information that could be useful. That information doesn’t even have to be relevant to the lawsuit, as long as it could possibly lead to the discovery of relevant information. The only way that a court will evaluate an identity-seeking subpena is if either the ISP or the target of the subpoena files a motion asking the judge to block the subpoena. Unfortunately, in practice that rarely happens. That is because these subpoenas usually have a short, roughly 7-day deadline, and because many people never even find out that their Internet data has been subpoenaed.
