N.J. Stat. § 2A:66-3
If, in a proceeding in lieu of prerogative writ to review an assessment for a local or public improvement, the assessment is set aside or reversed only as to the plaintiff in such proceeding, and the property in which such assessment was assessed is in fact liable to assessment in respect to the purpose for which such assessment was made, the superior court shall, upon application for that purpose, determine for what sum such property is liable to be assessed, and by its judgment fix the amount of such assessment. The assessment so fixed shall be and remain a first lien upon such property and collectible in the same manner as the balance of the original assessment.
This section shall not apply to any assessment set aside or reversed more than three years prior to the making of the application.
