Local Law 51 of 2008

Local Law 51 of 2008 is a New York City local law that amended the New York City Charter to increase the maximum number of consecutive full terms that the mayor, public advocate, comptroller, borough presidents, and members of the New York City Council may serve from two to three. The Council approved the measure on October 23, 2008, by a vote of 29–22, and Mayor Michael Bloomberg signed it into law on November 3, 2008.

The law allowed incumbents then in office to seek a third consecutive term in the 2009 New York City elections, including Bloomberg, who was subsequently re-elected to a third term as mayor.

Local Law 51 was noteworthy because New York City voters had previously approved a two-term limit by referendum in 1993 and rejected an extension to three terms in 1996.

In 2010, a charter revision referendum reduced the limit back to two consecutive terms for officials first elected at or after the 2010 general election and restricted the council's ability to alter term limits for sitting officeholders, effectively superseding Local Law 51 for future officials.
