Idaho R. App. P. 6
The original title of an action or proceeding, with the names of the parties in the same order, shall be retained on appeal by adding the designations of "appellant" and "respondent." In special proceedings the party prosecuting shall be designated the "petitioner" and the adverse party, if any, the "respondent." In an appeal in which there is no adverse party named in the title, there shall be added the name of the party prosecuting the appeal designated as "appellant." In an appeal from a decision or order of the Idaho Public Utilities commission filed by an intervenor in the original proceedings, the petitioner or applicant in the original proceedings shall be made a party to the appeal, and designated as a "respondent". The district court or administrative agency may be order correct the title of an appeal or cross-appeal at any time before the clerk's or agency's record is lodged as provided in Rule 29. The Supreme Court may amend a title of an appeal or proceeding before it at any time. All motions, petitions and other documents filed with the court should be typed on 8 1/2 x 11 inch paper. Prisoners incarcerated or detained in a state prison or county jail may file documents that are legibly hand-printed in black ink, in whole or in part, that otherwise conform to the requirements of these rules. Once a Supreme Court case number is assigned, all motions, briefs and other documents filed shall specify both the Supreme Court case number and the district court docket number, including county, or agency docket number from which the case originated. The original case number should appear below the Supreme Court case number.
