N.J. Stat. § 19:37-1
When the governing body of any municipality or of any county desires to ascertain the sentiment of the legal voters of the municipality or county upon any question or policy pertaining to the government or internal affairs thereof, and there is no other statute by which the sentiment can be ascertained by the submission of such question to a vote of the electors in the municipality or county at any election to be held therein, the governing body may adopt at any regular meeting an ordinance or a resolution requesting the clerk of the county to print upon the official ballots to be used at the next ensuing general election a certain proposition to be formulated and expressed in the ordinance or resolution in concise form. Such request shall be filed with the clerk of the county not later than 88 days previous to the election.
