Fair enough. Kindly show me the rule from the federal rules of civil procedure.
To show, what exactly? You agree that grand juries issue subpoenas before a person is charged, right? You agree that Congress issues subpoenas before a person is charged, right?
You know about how grand juries can force people to testify against themselves (before the grand jury) by giving them use immunity, right?
You claim to have graduated from a law school in the United States, right?
In cases that I'm in, if the opposing party won't come to a deposition or hearing, I file a motion to compel - not a subpoena. However, if I need to depose a non-party, I get a subpoena to ensure they'll come testify or produce documents. Maybe its different where you practice.
In this case we're talking about U.S. federal law, no?
(I guess that assumes the news got it right, that it was the
U.S., issuing a subpoena to
Mt. Gox. It's certainly possible that the reporter got the details wrong, and the subpoena came from a state, and/or was issued to an individual.)
