The notice of contest and any answer are the pleadings in the case and may be amended in the discretion of the supreme court. The contest proceedings must be brought as soon as practicable. The court shall proceed in the manner provided for the trial of civil actions so far as practicable, but must issue its decision at least one day before the deadline to submit the certificate of ascertainment as required under the laws of the United States.
