House committee substitute makes the following changes to the 2nd edition. 

Further amends section 13.2 of the Charter of the City of Durham, SL 1975-671, to allow the City Council to call for a special election to fill the unexpired portion of the term when there is a vacancy in the office of Mayor or Council, instead of appointing a person to fill the vacancy. Adds that if a State or county primary or general election, municipal primary or general election, referendum, or special election is scheduled to be held within 120 days of the date the vacancy occurs, and there are at least 10 days before the date by which mail-in absentee ballots must be available for voting in that scheduled election, the City Council must call for a special election to fill the vacancy for the remainder of the unexpired portion of the term to coincide with that scheduled election. Makes an additional clarifying change. Makes conforming changes to section 13.3.

Amends the act's short title.
