N.J. Stat. Ann. § 51:1-120

Any person who qualifies in the form and manner prescribed by the regulations authorized under the terms of this act to repair weighing or measuring devices shall receive a license to repair the classes or kinds of weighing devices for which he qualifies. Applicants who do not qualify shall not receive a license, it being provided, however, that the denial of a license at any time shall not prejudice the issue of a license at any later examination.
