The author of an opinion or the appropriate appellate court may correct typographical, grammatical, or other formal errors in the opinion by filing a correction notice with the clerk of the supreme court. The correction notice shall be filed and kept with the opinion, and the author or appropriate appellate court shall cause a corrected opinion to be filed with the clerk. The corrected opinion shall reflect the original date of filing as well as the date of the filing of the corrected opinion. The original opinion shall remain on file with the clerk. If the opinion is to be published in the West's North Western Reporter and has not yet been published in a bound volume, and if the correction did not originate with the publishing company, the author or appropriate appellate court shall cause a copy of the correction notice to be transmitted immediately to the publishing company for insertion of the correction in the published opinion.(2)Substantive changes to opinion. Changes in the substance of a supreme court opinion may be made only by action of that court before procedendo has been issued.

Such changes shall be made only by the filing of an order amending the opinion together with a substituted opinion. The substituted opinion shall reflect the original date of filing as well as the date of the filing of the substituted opinion. The original opinion shall remain on file with the clerk.Court Order December 5, 1979, effective 1/1/1980; 5/16/1984; 11/9/2001, effective 2/15/2002; 3/5/2013, effective 5/3/2013.
