The voters of that state, and people/organizations that have the time and money to pursue court battles. It's a long slow process, it is the process.
It's clear that in this state the majority of voters do NOT want consealed carry or even the second ammendment at all. The product of anti-gun brain washing by elected officials spanning generations
That fact however does not take away from the rights guaranteed to every INDIVIDUAL by the constitution even though NJ thinks it does. Court battles in NJ are one sided and crooked. Our rights will never be won at a state level and SCOTUS picks and chooses what it wants to hear. Not that I have any faith in SCOTUS if they did hear a case.
