4. The action shall be placed at the top of the civil docket. Insofar as the action challenges the summary statement portion of the official ballot title, the court shall consider the petition, hear arguments, and in its decision certify the summary statement portion of the official ballot title to the secretary of state. Insofar as the action challenges the fiscal note or the fiscal note summary portion of the official ballot title, the court shall consider the petition, hear arguments, and in its decision, either certify the fiscal note or the fiscal note summary portion of the official ballot title to the secretary of state or remand the fiscal note or the fiscal note summary to the auditor for preparation of a new fiscal note or fiscal note summary pursuant to the procedures set forth in section 116.175 . Any party to the suit may appeal to the supreme court within ten days after a circuit court decision. In making the legal notice to election authorities under section 116.240 , and for the purposes of section 116.180 , the secretary of state shall certify the language which the court certifies to him.

5. Any action brought under this section that is not fully and finally adjudicated within one hundred eighty days of filing, and more than fifty-six days prior to election in which the measure is to appear, including all appeals, shall be extinguished, unless a court extends such period upon a finding of good cause for such extension. Such good cause shall consist only of court-related scheduling issues and shall not include requests for continuance by the parties.
