(1) Within sixty-three days after the last day on which statements of opposition may be filed with respect to a particular application, unless such time is extended by the water judge for good cause shown, the referee shall make a ruling on the application unless the referee determines to rerefer the matter to the water judge as specified in subsection (2) of this section. The ruling may disapprove the application in whole or in part in the discretion of the referee even though no statements of opposition have been filed. The ruling of the referee shall give the names of the applicants with respect to each water right or conditional water right involved, the location of the point of diversion or place of storage, the means of diversion, the type of use, the amount and priority, and other pertinent information. In the case of a plan for augmentation, such ruling shall include a complete statement of such plan as approved or disapproved. The ruling shall be filed with the water clerk, subject to judicial review. A copy of the ruling shall be sent by the water clerk by regular or electronic mail to the applicant, to each person who has filed a statement of opposition, to the state engineer, and to the division engineer.

(2) The referee may determine not to make a ruling as specified in subsection (1) of this section and to rerefer the matter to the water judge for a decision as provided in this article. Such rereferral shall be accomplished by order of the referee, which shall be entered within sixty-three days following the last month in which statements of opposition may be filed with respect to the particular application, unless such time is extended by the water judge for good cause shown. The referee shall rerefer the matter to the water judge at any time before the referee's hearing upon a motion to rerefer by the applicant or any opposer certifying that party's intent to protest an adverse ruling of the referee. A motion to rerefer shall not be a prerequisite to a protest of the ruling of the referee. A copy of the order shall be sent by the water clerk to the applicant and to each person who has filed a statement of opposition and to the state engineer and the division engineer by regular or electronic mail.
