In misdemeanor cases, if a pretrial conference is held, the motion must be heard then unless the court directs otherwise for the purpose of hearing witnesses, or for other good cause. If the motion is not heard at a pretrial conference, it must be heard before trial, unless the court - upon agreement by the prosecutor and defense attorney - hears and determines the motion at arraignment. If the court hears the motion at the arraignment, it need not be in writing, but a record must be made of the proceedings, and witnesses can be called in the court's discretion. The motion must be determined before trial as provided in Rule 12.07.

Rule 10 does not require pre-trial motions to be made before a plea is entered.
As a general rule, under Rule 10.02 no challenge to the court's personal jurisdiction can be made in a misdemeanor case until after a complaint has been filed. Therefore, a defendant must first demand a complaint under Rule 4.02, subd. 5(3) before raising the jurisdictional challenge. If no complaint is issued, the charge must be dismissed under Rule 4.02, subd. 5(3). If a complaint is issued, it will often make any possible challenge moot, since a valid complaint would give the court jurisdiction even if the arrest was illegal. See City of St. Paul v. Webb, 256 Minn. 210, 97 N.W.2d 638 (1959). Once the complaint is issued, the jurisdictional challenge becomes a sufficiency of the complaint question.
If the defendant's motion to dismiss is denied, Rule 17.06, subd. 4(1) provides that the defendant can continue to raise the jurisdictional issue on direct appeal if convicted after a trial. This procedure avoids the necessity of seeking review by an extraordinary writ that oftentimes would delay a trial otherwise ready to proceed.
Rule 17.06, subd. 4 describes the effect of determining a motion to dismiss under this rule.
In misdemeanor cases, Rule 10.03, subd. 2 provides an alternative method to dispose of a motion to dismiss - including a motion to dismiss for want of personal jurisdiction - at the time of arraignment. When there is no dispute over the facts, and the law can be quickly and adequately argued, this alternative procedure can provide an immediate disposition and avoid the delay and expense of further court appearances.
