N.J. Stat. § 19:63-17.1: Determination of validity of mail-in ballot.

4. a. Following the attempt to cure any alleged deficiencies in a mail-in ballot pursuant to section 17 of P.L.2009, c.79 (C.19:63-17), the county board of elections shall make a final determination about whether or not the mail-in ballot alleged to be deficient shall be counted. The failure or alleged failure of any voter to cure alleged deficiencies in the voter's mail-in ballot shall not create a presumption that the vote is improper or invalid, nor shall it be considered evidence that the vote is improper or invalid.

b. Following final determination under subsection a. of this section, disputes about the qualifications of a voter to vote, or about whether or not or how any mail-in ballot shall be counted in that election, shall be referred to the Superior Court for determination.
