(a)When and how taken. When an appeal is permitted by law from a district court to an appellate court, the time within which an appeal may be taken shall be 30 days from the entry of the judgment, as provided by K.S.A. 60-258, and amendments thereto, except that upon a showing of excusable neglect based on a failure of a party to learn of the entry of judgment the district court in any action may extend the time for appeal not exceeding 30 days from the expiration of the original time herein prescribed. The running of the time for appeal is terminated by a timely motion made pursuant to any of the rules hereinafter enumerated, and the full time for appeal fixed in this subsection commences to run and is to be computed from the entry of any of the following orders made upon a timely motion under such rules: Granting or denying a motion for judgment under K.S.A. 60-250(b), and amendments thereto; or granting or denying a motion under K.S.A. 60-252(b), and amendments thereto, to amend or make additional findings of fact, whether or not an alteration of the judgment would be required if the motion is granted; or granting or denying a motion under K.S.A. 60-259, and amendments thereto, to alter or amend the judgment; or denying a motion for new trial under K.S.A. 60-259, and amendments thereto. A party may appeal from a judgment by filing with the clerk of the district court a notice of appeal. Failure of the appellant to take any of the further steps to secure the review of the judgment appealed from does not affect the validity of the appeal, but is ground only for such remedies as are specified in this chapter, or when no remedy is specified, for such action as the appellate court having jurisdiction over the appeal deems appropriate, which may include dismissal of the appeal. If the record on appeal has not been filed with the appellate court, the parties, with the approval of the district court, may dismiss the appeal by stipulation filed in the district court, or that court may dismiss the appeal upon motion and notice by the appellant.
