New Jersey Statutes Title 19. Elections 19 § 7-4

The county board shall thereupon issue, under the hands of its members, to the persons named in such appointment papers, or application, permits for them to act as challengers for their respective parties or candidates or for or against a public question at the election district or election districts specified, as the case may be. Such permits shall be filed by the persons named therein with the district board or district boards named therein, as evidence of their authority to be present in the polling place, and they may be issued and revoked and others issued in their stead at any time up to and including the day of election. When a permit shall be revoked, the permit in the place thereof shall be issued upon the nomination of the same person or officer upon whose nomination the original permit was issued.

A challenger appointed pursuant to paragraph 2 of subsection b. of R.S.19:7-1 shall be issued a county-wide permit that is to be presented to any district board within the county as evidence of the challenger's authority to be present at the polling place during an election. Upon leaving the polling place, such a challenger must reclaim the permit from the district board to gain entry to any other polling place in the county during the election.
