Beth, your missing the fact that they went out and turned the utility back on when it had been disconnected. That is Theft of Service.
What will happen is the utility company will come out to reinstate the power when paid, and see that their lock has been removed. As such, they could file theft charges against you.
New Jersey Statute:
"2C:20-8. Theft of services
a. A person is guilty of theft if he purposely obtains services which he knows are available only for compensation, by deception or threat, or by false token, slug, or other means, including but not limited to mechanical or electronic devices or through fraudulent statements, to avoid payment for the service. "Services" include labor or professional service; transportation, telephone, telecommunications, electric, water, gas, cable television, or other public service; accommodation in hotels, restaurants or elsewhere; entertainment; admission to exhibitions; use of vehicles or other movable property. Where compensation for service is ordinarily paid immediately upon the rendering of such service, as in the case of hotels and restaurants, absconding without payment or offer to pay gives rise to a presumption that the service was obtained by deception as to intention to pay.
b. A person commits theft if, having control over the disposition of services of another, to which he is not entitled, he knowingly diverts such services to his own benefit or to the benefit of another not entitled thereto.
c. Any person who, without permission and for the purpose of obtaining electric current, gas or water with intent to defraud any vendor of electricity, gas or water or a person who is furnished by a vendor with electric current, gas or water:
(1) Connects or causes to be connected by wire or any other device with the wires, cables or conductors of any such vendor or any other person; or
(2) Connects or disconnects the meters, pipes or conduits of such vendor or any other person or in any other manner tampers or interferes with such meters, pipes or conduits, or connects with such meters, pipes or conduits by pipes, conduits or other instruments--is guilty of a disorderly persons offense.
The existence of any of the conditions with reference to meters, pipes, conduits or attachments, described in this subsection, is presumptive evidence that the person to whom gas, electricity or water is at the time being furnished by or through such meters, pipes, conduits or attachments has, with intent to defraud, created or caused to be created with reference to such meters, pipes, conduits or attachments, the condition so existing; provided, however, that the presumption shall not apply to any person so furnished with gas, electricity or water for less than 31 days or until there has been at least one meter reading.
A violation of this subsection shall be deemed to be a continuing offense as long as the conditions described in this subsection exist.
d. Any person who, without permission or authority, connects or causes to be connected by wires or other devices, any meter erected or set up for the purpose of registering or recording the amount of electric current supplied to any customer by any vendor of electricity within this State, or changes or shunts the wiring leading to or from any such meter, or by any device, appliance or means whatsoever tampers with any such meter so that the meter will not measure or record the full amount of electric current supplied to such customer, is guilty of a disorderly persons offense.
The existence of any of the conditions with reference to meters or attachments described in this subsection is presumptive evidence that the person to whom electricity is at the time being furnished by or through such meters or attachments has, with intent to defraud, created or caused to be created with reference to such meters or attachments, the condition so existing; provided, however, that the presumption shall not apply to any person so furnished with electricity for less than 31 days or until there has been at least one meter reading.
A violation of this subsection shall be deemed to be a continuing offense as long as the conditions described in this subsection exist.
