§ La. R.S. 18:410.6(untitled)

Death of a candidate; procedure; selection of party nominee
A. When a person who qualified as a candidate in a party primary election to be the party nominee
for a party primary office dies after the close of the qualifying period and before the time for closing the polls
on the day of that party primary election, the name of the deceased candidate shall not be printed on the party
primary election ballot. If the party primary election ballot was printed with the deceased candidate's name
on it, any votes received by the deceased candidate shall be void and shall not be counted for any purpose
whatsoever.
B.(1) If as the result of the death of a candidate in a party primary election, a major political party
has no party nominee qualified for the general election, the major political party shall select, in the manner
provided in its bylaws, the party nominee who shall meet all of the qualifications for the party primary office.
(2) The chairman of the state central committee of the major political party shall transmit an
attestation to the secretary of state containing the name of the party nominee, the signature of the chairman
of the state central committee, the signature of the party nominee, and any other information required by the
form of the attestation prescribed by the secretary of state. The attestation shall be filed as soon as possible
after the death of the party's candidate, but no later than noon on the seventh day prior to the general election
day. If the attestation is received no later than 4:30 p.m. on the seventh day after the close of the qualifying
period for nonparty primary offices for the fall primary election, the secretary of state shall print the name
of the selected party nominee on the ballot. If the attestation is filed in accordance with this Paragraph, but
the name of the selected party nominee is not placed on the ballot, there shall be a notice regarding the
selected party nominee posted at each polling place and on the website of the secretary of state. If the
selected party nominee's name is not placed on the ballot, all votes cast for the party's deceased candidate
shall be attributed to the party nominee.
(3) If the party nominee dies after noon on the seventh day prior to general election day, there shall
be no selected party nominee, and no attestation shall be filed with or accepted by the secretary of state. All
votes cast for the deceased party nominee shall be counted, and if the deceased party nominee obtains the
most votes cast for the party primary office in the general election, a vacancy in the party primary office shall
be declared.
