(a) If a vacancy occurs in the office of Representative in Congress on or after August 1 in an even-numbered year and prior to the statewide general election in such year, the Governor shall order a special election to be held in conjunction with such statewide general election. The only candidates who may appear on the ballot for such office at such special election are those who were nominated at the statewide primary election in such year, those who comply with section 32-616, and those who comply with section 32-627 to fill a vacancy on the ballot if such a vacancy exists. The candidate receiving the most votes at such special election shall serve for the remainder of the vacated term and for the succeeding term of office;

(b) If a vacancy occurs in the office of Representative in Congress on or after the day of the statewide general election and prior to the end of the term of the office which is vacated, no special election shall be called; and

(c) If a vacancy occurs in such office at any time other than as described in subdivision (a) or (b) of this subsection, the Governor shall order a special election to be held not less than seventy-five days nor more than ninety days after the vacancy occurs. Such election shall be held on a Tuesday. Each political party which polled at least five percent of the entire vote in the district in which the vacancy occurs may select a candidate following the applicable procedures in subsection (2) of section 32-627, except that the certificate and filing fee shall be submitted at least sixty-seven days prior to the day of the election. Any candidate so selected shall have his or her name placed on the ballot with the appropriate political party designation.

The writ of election shall specify the date of a special election to fill such vacancy to be held within forty-nine days after the Speaker's announcement.

(b) The Secretary of State shall notify the chairperson and secretary of each political party which polled at least five percent of the entire vote in the district in which the vacancy occurs that the party may select a candidate following the applicable procedures in subsection (2) of section 32-627, except that the certificate and filing fee shall be submitted within seven days after notification by the Secretary of State. Any candidate so selected shall have his or her name placed on the ballot with the appropriate political party designation.
