Curia. A juror has no occasion for a writ to protect him. If a juror, or any other person, whose duty brings him to Court, whether as a party or a witness, is arrested while attending the Court, or eundo et redeundo, the Court, upon motion, will take order for his discharge. A writ of protection will not protect one who is not lawfully entitled to it, and is of no other use to one who is so entitled, but as prima facie evidence to the officer who is about to arrest him.
