73.4      Execution of consent - The clerk shall not accept a consent form unless it has been signed by all the parties in a case. No consent form will be made available, nor will its contents be made known, to any judge, unless all parties have consented to the reference to a magistrate judge. No magistrate judge or other court official may attempt to persuade or induce any party to consent to the reference of any matter to a magistrate judge. This rule, however, shall not preclude a district judge or magistrate judge from informing the parties that they have the option of consenting to a magistrate judge.
