Which of the following NJSA codes pertains to elections?

The correct answer pertains to NJSA 19, which specifically covers the laws and regulations concerning elections in New Jersey. This statute outlines the procedures for conducting elections, including voter registration, the duties of election officials, and the conduct of voters. Understanding NJSA 19 is crucial for anyone involved in municipal operations, as it governs the foundational framework that ensures fair and democratic elections in the state.

Other codes, while significant in their own right, do not address electoral processes or election law specifically. For instance, NJSA 18 relates to education matters, NJSA 20 governs the limitations on actions and suits in New Jersey, and NJSA 21 addresses miscellaneous public matters. Therefore, NJSA 19 is the only designation focused entirely on elections, making it the right choice in this context.
