Self Defense

The United States Constitution and our State laws permit us to protect ourselves. As a homeowner, there are legal measures that can be used to keep out intruders. The Second Amendment to the US Constitution provides that we have the right to bear arms. Obviously, civilized society is permitted to have certain restrictions on gun and weapon use.
The basic question many people have is if they defend themselves and the attacker claims they are hurt, can you be liable. There are two vastly different grounds for liability: criminal liability and civil liability.
Self-Defense and Avoiding Criminal Responsibility
A person may use force against another person if he reasonably believes that such force is immediately necessary for the purpose of protecting himself against the use of unlawful force by such other person. Such justifiable use of force is commonly call "self-defense." The provisions for self-defense to protect citizens from criminal charges is found in the criminal code at NJSA 2C-3-4(a), which states in part:
"... The use of force upon or toward another person is justifiable when the actor reasonably believes that such force is immediately necessary for the purpose of protecting himself against the unlawful force by such other person on the present occasion."
In other words, self defense is the right of a person to defend against any unlawful force. Self defense is also the right of a person to defend against seriously threatened unlawful force that is actually pending or reasonably anticipated.
When a person is in imminent danger of bodily harm, the person has the right to use force or even deadly force when that force is necessary to prevent the use against (him/her) of unlawful force. The force used by the defender must not be significantly greater that and must be proportionate to the unlawful force threatened or used against the defender.
Unlawful force is defined as force used against a person without the persons consent in such a way that the action would be a civil wrong or a criminal offense.
If the force used by the defender was not immediately necessary for the defenders protection or if the force used by the defender was disproportionate in its intensity, then the use of such force by the defendant was not justified and the self defense claim in a criminal prosecution falls.
Deadly Force and Criminal Prosecution
The use of deadly force may be justified only to defend against force or the threat of force of nearly equally severity and is not justifiable unless the defendant reasonably believes that such force is necessary to protect (himself/herself) against death or serious bodily harm. By serious bodily harm, we mean an injury that creates substantial risk of death or which causes serious permanent disfigurement or which causes a protracted loss or impairment of the function of any bodily member or organ.
One cannot respond with deadly force to a threat of or even an actual minor attack. For example, a slap or an imminent threat of being pushed in a crowd would not ordinarily justify the use of deadly force to defend against such unlawful conduct.
In addition, one can under limited instances use force in the protection of others (NJSA 2C:35-5). Limited force under certain instances is also afforded in the criminal code for the defense of personal property (NJSA 2C:3-6C).
Defense of Real Property (Your Home) and Criminal Liability
A section of our criminal law provides that:
"the use of force upon or toward the person of another is justifiable when the actor is in possession or control of premises or is licensed or privileged to be thereon and he reasonably believes such force necessary to prevent or terminate what he reasonably believes to be the commission or attempted commission of a criminal trespass by such other person in or upon such premises."
A person commits a criminal trespass if, knowing that (he/she) is not licensed or privileged to do so, (he/she) enters or surreptitiously remains in any structure or separately secured or occupied portion thereof.
Our criminal law further provides that, in defense of your home:
"the use of force is justifiable...only if the actor first requests the person against whom such force is used to desist from his interference with the property, unless the actor reasonably believes that (a) such request would be useless; (b) it would be dangerous to himself or another person to make the request or (c) substantial harm will be done to the physical condition of the property which is sought to be protected before the request can effectively be made."
"The use of deadly force is not justifiable in the defense of premises unless the actor reasonably believes that:
(a) The person against whom the force is used is attempting to dispossess him of his dwelling otherwise than under a claim of right to its possession; or
(b) The person against whom the force is used is attempting to commit or consummate arson, burglary, robbery or other criminal theft or property destruction; except that
(c) Deadly force does not become justifiable under subsections (a) and (b) unless
(i) The person against whom it is employed has employed or threatened deadly force against or in the presence of the actor; or
(ii) The use of force other than deadly force to prevent the commission or the consummation of the crime would expose the actor or another in his presence to substantial danger of serious bodily harm."
These are taken from portions of the Model Jury Charges - Criminal, Third Edition, published by the New Jersey Institute for Continuing Legal Education. It should be noted that these are defenses to criminal charges which will be brought against you if you defended yourself.
Even if the County Prosecutor or Police decide not to bring criminal charges against you or if you are successful in proving that you were protecting yourself as permitted under certain provisions of the criminal code, the attacker if injured still may attempt to bring a civil suit to recover for any medical expenses or injuries incurred.
Defenses to Civil Liability
Ordinarily, if someone is injured as a result of the intentional or negligent act of another, they can recover monetary damages to reimburse them for medical bills and injuries suffered. However, this is not always so when the person was injured while attacking someone else or attempting to steal from that person.
The judge in a civil case will instruct jurors in the following easy to read language: "No person has a lawful right to lay hostile and menacing hands on another. However, the law does not require anyone to submit meekly to the unlawful infliction of violence upon him. He may resist the use or threatened use of force upon him. He may meet force with force, but he may use only such force as reasonably appears to him to be necessary under all the circumstances for the purpose of self protection.
One is not ordinarily expected to exercise the same refined degree of judgment at times of great stress or excitement that he would under more placid circumstances.
Deadly Force and Civil Duty to Retreat
A deadly force is not justifiable when an opportunity to retreat with complete safety is known by the defender to be at hand. The use of such force is not justifiable if the defender knew that it could have been avoided with complete safety to himself by retreating. Where these conditions are present, the defender has a duty to retreat, and his use of a deadly force under these circumstances cannot be justified as an act of self defense.
Defense of Others
One may justifiably intervene in defense of any person who is in actual or apparent imminent danger of death or serious bodily harm, and in so doing he may use such force as he has reason to believe, and does believe, necessary under the circumstances. The defender must be reasonable in his belief that the third party is in dire peril of death or serious bodily harm. He must also have a reasonable basis to believe that the force he uses is necessary to protect the apparent victim from the threatened harm.
The defender has the burden of proving to the jurors that he inflicted the injuries complained of while acting in defense of the third party within the foregoing principles.
One is not permitted to set up traps to kill or maim individuals who attempt to trespass on their property. There is a responsibility to warn trespassers of dangerous conditions and an intenant risk of injuries. You cannot have a deep pit to catch trespassers or electric wire with one million volts of electricity to kill a trespasser.
Liability for Dog Bites
If someone hops your fence, trespasses on your land, and your dog bites him, you are not liable. However, New Jersey does impose strict liability if your dog bites someone if it is loose or if the person bitten was in a public place or permitted on your property. NJSA 4:19-16 provides,
"The owner of any dog which shall bite a person while such person is on or in a public place, or lawfully on or in a private place, including the property of the owner of the dog, shall be liable for such damages as may be suffered by the person bitten, regardless of the former viciousness of such dog or the owners knowledge of such viciousness.
"For the purpose of this section, a person is lawfully upon the private property of such owner when he is on the property in the performance of any duty imposed upon him by the laws of this state or the laws or postal regulations of the United States, or when he is on such property upon the invitation, express or implied, of the owner thereof."
Thus, in New Jersey, a dog does not get two bites.
A person can even be liable if your dog injures someone although not biting it. Being jumped on or chased by a dog could be grounds for a civil liability. It is also strict liability if any of your dangerous animals injure someone, i.e. pet, buffalo or tiger.
Conclusion
Self defense has been recognized in both the criminal code and civil liability cases. It is common sense under the circumstances that usually controls liability. For more detailed information on self defense, you should carefully read the New Jersey statutes dealing with criminal responsibility and self defense.
It is also important to note that in intentional acts usually your insurance company will not defend you or pay another person who is injured on your property as a result of intentional acts. You should personally speak with your homeowners insurance broker to ask them to show you specifically in your policy where you are covered for injuries to someone.

(b)The actor knows that he can avoid the necessity of using such force with complete safety by retreating or by surrendering possession of a thing to a person asserting a claim of right thereto or by complying with a demand that he abstain from any action which he has no duty to take, except that:
(i)The actor is not obliged to retreat from his dwelling, unless he was the initial aggressor; and
(ii)A public officer justified in using force in the performance of his duties or a person justified in using force in his assistance or a person justified in using force in making an arrest or preventing an escape is not obliged to desist from efforts to perform such duty, effect such arrest or prevent such escape because of resistance or threatened resistance by or on behalf of the person against whom such action is directed.

(a)The actor reasonably believed that the intruder would inflict personal injury upon the actor or others in the dwelling; or
(b)The actor demanded that the intruder disarm, surrender or withdraw, and the intruder refused to do so.
(3)An actor employing protective force may estimate the necessity of using force when the force is used, without retreating, surrendering possession, withdrawing or doing any other act which he has no legal duty to do or abstaining from any lawful action.

2C:3-11. Definitions Definitions. In this chapter, unless a different meaning plainly is required: a. "Unlawful force" means force, including confinement, which is employed without the consent of the person against whom it is directed and the employment of which constitutes an offense or actionable tort or would constitute such offense or tort except for a defense (such as the absence of intent, negligence, or mental capacity; duress, youth, or diplomatic status) not amounting to a privilege to use the force. Assent constitutes consent, within the meaning of this section, whether or not it otherwise is legally effective, except assent to the infliction of death or serious bodily harm.
b. "Deadly force" means force which the actor uses with the purpose of causing or which he knows to create a substantial risk of causing death or serious bodily harm. Purposely firing a firearm in the direction of another person or at a vehicle, building or structure in which another person is believed to be constitutes deadly force. A threat to cause death or serious bodily harm, by the production of a weapon or otherwise, so long as the actors purpose is limited to creating an apprehension that he will use deadly force if necessary, does not constitute deadly force.
c. "Dwelling" means any building or structure, though movable or temporary, or a portion thereof, which is for the time being the actors home or place of lodging except that, as used in 2C:3-7, the building or structure need not be the actors own home or place of lodging.
d. "Serious bodily harm" means bodily harm which creates a substantial risk of death or which causes serious, permanent disfigurement or protracted loss or impairment of the function of any bodily member or organ or which results from aggravated sexual assault or sexual assault.
e. "Bodily harm" means physical pain, or temporary disfigurement, or impairment of physical condition.
