you have 5 defendants and the sixth one is for your AUSA (I mean US Attorney for your district, it may not be the same guy who filed appearance form). You still need to send a copy of the complaint to AUSA and all 5 defendants. Send a copy of summons for other defendants to AUSA as well (photocopy will do). If you sign a consent for a magistrate judge, it will more likely speed up the process.
thank you very much!
Is there any adverse effect for magistrate judge? What's your suggestion? sign it or not?
