New cases are generally referred to a magistrate judge for non-dispositive matters, including the preliminary pretrial conference. The magistrate judge will schedule a preliminary pretrial conference about 30-60 days after the last appearance for a party. Counsel should read and follow the directives contained in the magistrate judge's "Order of Preliminary Pretrial Conference."
After the magistrate judge enters a scheduling order, Judge Miller will schedule a conference at which he will set a deadline for dispositive motions, as well as the dates for trial and the final pretrial conference. Judge Miller won't entertain motions to extend the discovery deadline at that motion as long as the reference to the magistrate judge is in place, lest he and the magistrate judge end up with conflicting orders.
