Idaho Code § 34-2015
The proceedings shall not be dismissed for want of form, if the particular causes of contest are alleged with such certainty as will sufficiently advise the incumbent of the real grounds of contest. If any part of the causes are held insufficient they may be amended, but the incumbent will be entitled to an adjournment if he state on oath that he has a matter to answer to the amended causes, for the preparation of which he needs further time. Such adjournment shall be upon such terms as the court deems reasonable; but if all the causes are held insufficient, and an amendment is asked the adjournment shall be at the cost of the contestant. If no amendment is asked for or made, or in case of entire failure to prosecute, the proceedings may be dismissed.
