From NJ.com:

McGovern initially applied for a permit to purchase a handgun in 2011. The city denied his application, saying McGovern refused to fill out special forms that the city includes with its application. The city also cited three times McGovern was arrested for misdemeanor offenses in Florida about a decade before (McGovern said he was not convicted; the city asked for proof).

In October 2012, a trial court ruled in Jersey City’s favor. In April 2014, an appellate court reversed that decision, ruling that Jersey City veered outside of its authority by demanding “substantially more” information on its gun-permit application than state law allows.
