Election law is a broad category of state and federal laws—statutes, constitutions, and case law (court opinions)—and includes issues related to voter eligibility; voting methods and processes; vote tabulations and recounts; and the financing and expenditures of state and federal political campaigns.

In New Jersey, election law is governed by both state statutes and federal laws. State statutes cover a range of issues including voter registration requirements, the conduct of elections, and the procedures for vote counting and recounts. New Jersey law requires voters to be U.S. citizens, residents of the county for at least 30 days before the election, and at least 18 years old by the time of the next election. The state also has provisions for absentee voting and increasingly for mail-in ballots. Voting methods and processes are detailed in the New Jersey Statutes, and the state has moved towards the use of electronic voting systems with paper audit trails. Regarding campaign finance, New Jersey has its own set of regulations that govern campaign contributions, expenditures, and reporting requirements, which are enforced by the New Jersey Election Law Enforcement Commission (ELEC). These state laws exist alongside federal regulations, such as the Federal Election Campaign Act (FECA), which regulates the financing of federal elections, and the Voting Rights Act, which protects the voting rights of individuals. It's important to note that election laws are subject to change, and legal challenges in court can also affect how these laws are interpreted and applied.
