If pertinent and significant authorities come to a party's attention after the party's brief has been filed or after oral argument but before decision, a party may promptly file a letter with the clerk of the appellate courts setting forth the citations. The letter must state without argument the reasons for the supplemental citations, referring either to the page of the brief or to the point argued orally. Proof of service shall be made as defined by Rule 125.04. Any response must be made promptly and must be similarly limited.
Minn. R. Civ. App. P. 128.05
Rule 128.05is a new provision in the Minnesota Rules. It is patterned after FED. R. APP. P. 28(j), and is intended to allow a party to submit additional authorities to the court without requiring a motion and without providing an opportunity for argument. The rule contemplates a very short submission, simply providing the citation of the new authority and enough information so the court can determine what previously-made argument it relates to. The submission itself is not to contain argument, and a response, if any, is similarly constrained. Because a response is limited to the citation of authority and cannot provide argument, a response most frequently will not be necessary or proper. A submission or reply that does not conform to the rule is subject to being stricken. See, e.g., Esicorp, Inc. v. Liberty Mut. Ins. Co., 193 F.3d 966, 972 (8th Cir. 1999) (granting motion to strike argumentative submission); Anderson v. General Motors Corp., 176 F.3d 488 (10th Cir. 1999) (unpublished) (same).
