The part of the TRO that stood up was section 24
A4769] 7. (New section) Places where the carrying of a weapon is prohibited.
a. Except as otherwise provided in this section, it shall be a crime of the third degree for any person, other than a person lawfully carrying a firearm within the authorized scope of an exemption set forth in N.J.S.2C:39-6 and only to the extent permitted by the entity responsible for security at the place in question, to knowingly carry a weapon, as defined in subsection r. of N.J.S.2C:39-1, in any of the following places, including in or upon any part of the buildings, grounds, or parking area of:
(24) private property, including but not limited to residential, commercial, industrial, agricultural, institutional or undeveloped property, unless the owner has provided express consent or has posted a sign indicating that it is permissible to carry on the premises a concealed handgun with a valid and lawfully issued license under N.J.S.2C:58-4;
Part 24 is not enforceable under the TRO. There is no prior signage law to fall back upon if this part of the law is negated that I know of.
