Nebraska Revised Statute 32-627
Chapter 32 Section 627
Partisan office; vacancy on ballot; how filled.
(1) If a vacancy on the ballot arises for any partisan office except President and Vice President of the United States before a general election, the vacancy shall be filled by the majority vote of the proper committee of the same political party. If the vacancy exists for an office serving only a particular district of the state, only those members of the political party committee who reside within that district shall participate in selecting the candidate to fill the vacancy. No vacancy on the ballot shall be deemed to have occurred if a political party makes no nomination of a candidate at the primary election for the office. If a vacancy on the ballot arises for Governor, the vacancy shall be filled by the majority vote of the proper committee of the same political party, and the candidate for Governor shall select a person of the same political party to be the candidate for Lieutenant Governor on the general election ballot. If a vacancy on the ballot arises for the Lieutenant Governor on or before September 1, the candidate for Governor shall select a new candidate for Lieutenant Governor in the same manner as required in section 32-619.01.
(2) The chairperson and secretary of the executive committee for the political party shall make and file with the filing officer a certificate setting forth the cause of the vacancy, the name of the person so nominated, the office for which he or she was nominated, the name of the person for which the new nominee is to be substituted, the place of residence of the person so nominated, the street and number of the residence or place of business of the person so nominated if such person resides in a city, and the name of the political party with which the person so nominated affiliates which such committee represents. The certificate shall be signed by the chairperson and secretary with the name and places of their residences and sworn to by them before some officer authorized to administer oaths. If there is no executive committee of the political party or in lieu of the executive committee filling such vacancy, a mass convention of the political party may fill the vacancy and the chairperson and secretary of such convention shall make and file with the filing officer a certificate in form and manner substantially as is required to be filed by the chairperson and secretary of the executive committee under this subsection. The certificate shall be filed by September 1 for a general election and have the same force and effect as the candidate filing form provided for in section 32-607. The filing fee charged to candidates for such offices shall accompany the filing of the certificate.
