(a) In any prosecution for an offense, it is an affirmative defense that, at the time of the conduct charged, as a result of mental illness or serious mental disorder, the accused lacked substantial capacity to appreciate the wrongfulness of the accused’s conduct. If the defendant prevails in establishing the affirmative defense provided in this subsection, the trier of fact shall return a verdict of “not guilty by reason of insanity.”

(b) Where the trier of fact determines that, at the time of the conduct charged, a defendant suffered from a mental illness or serious mental disorder which substantially disturbed such person’s thinking, feeling or behavior and/or that such mental illness or serious mental disorder left such person with insufficient willpower to choose whether the person would do the act or refrain from doing it, although physically capable, the trier of fact shall return a verdict of “guilty, but mentally ill.”

(c) It shall not be a defense under this section if the alleged insanity or mental illness was proximately caused by the voluntary ingestion, inhalation or injection of intoxicating liquor, any drug or other mentally debilitating substance, or any combination thereof, unless such substance was prescribed for the defendant by a licensed health-care practitioner and was used in accordance with the directions of such prescription. As used in this chapter, the terms “insanity” or “mental illness” do not include an abnormality manifested only by repeated criminal or other antisocial conduct.

(a) The procedures for examination of the accused by the accused’s own psychiatrist or by a psychiatrist employed by the State and the circumstances under which such an examination will be permitted may be prescribed by rules of the court having jurisdiction over the offense.

(b) A psychiatrist or other expert testifying at trial concerning the mental condition of the accused shall be permitted to make a statement as to the nature of the examination, the psychiatrist’s or expert’s diagnosis of the mental condition of the accused at the time of the commission of the offense charged and the psychiatrist’s or expert’s opinion as to the extent, if any, to which the capacity of the accused to appreciate the wrongfulness of the accused’s conduct or to choose whether the accused would do the act or refrain from doing it or to have a particular state of mind which is an element of the offense charged was impaired as a result of mental illness or serious mental disorder at that time. The psychiatrist or expert shall be permitted to make any explanation reasonably serving to clarify the diagnosis and opinion and may be cross-examined as to any matter bearing on the psychiatrist’s or expert’s competence or credibility or the validity of the diagnosis or opinion.

11 Del. C. 1953, §  402;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1;  78 Del. Laws, c. 224, §  4; 

(a) Upon the rendition of a verdict of “not guilty by reason of insanity,” the court shall, upon motion of the Attorney General, order that the person so acquitted shall forthwith be committed to the Delaware Psychiatric Center.

(b) Except as provided in subsection (c) of this section below, a person committed, confined or transferred to the Delaware Psychiatric Center in accordance with subsection (a) of this section, § 404, § 405, § 406 or § 408 of this title (referred to herein as “the patient”) shall be kept there at all times in a secured building until the Superior Court of the county wherein the case would be tried or was tried is satisfied that the public safety will not be endangered by the patient’s release. The Superior Court shall without special motion reconsider the necessity of continued detention of a patient thus committed after the patient has been detained for 1 year. The Court shall thereafter reconsider the patient’s detention upon petition on the patient’s behalf or whenever advised by the Psychiatric Center that the public safety will not be endangered by the patient’s release.

(c) (1) Upon petition by a patient confined pursuant to this section, § 404, § 405, § 406 or § 408 of this title, or upon petition by the Center Director of the Delaware Psychiatric Center, the Court may permit housing in an unsecured building or participation by the patient in any treatment program that is offered by the Center, which requires or provides that the patient be placed outside a secured building. Such participation shall include, but not be limited to, employment off hospital grounds, job interviews, family visits and other activities inside and outside the Center, as may be prescribed by the Medical Director in the interest of rehabilitation.

(2) The petition shall include an affidavit from the Medical Director which states that the patient has not exhibited dangerous behavior during the last year of confinement and that in the opinion of the Medical Director, the patient will benefit from such participation.

(3) The petition shall set forth any specific treatment program being sought; the specific goals and course of treatment involved; and a schedule for periodic judicial reevaluation of the patient’s treatment status, all of which shall be subject to the Court’s approval and modification.

(4) Copies of the petition shall be served on the Attorney General, the Medical Director and the patient or the patient’s counsel or guardian.

(5) There shall be a judicial hearing on the petition, and any person or agency served with a copy of the petition, or a representative of such person or agency, shall have the right to testify, present evidence and/or cross-examine witnesses. The patient shall have the right to be represented by counsel at any proceeding held in accordance with this section. The Court shall appoint counsel for the patient if the patient cannot afford to retain counsel.

(6) Upon conclusion of a hearing on a petition pursuant to this section, the Court may approve, modify or disapprove any request or matter within the petition. If the patient’s participation in any treatment program is approved, such approval or participation shall be effective for not longer than 6 months from the date of the judge’s signature on the petition or order permitting such participation. Immediately prior to the conclusion of the 6-month period, the Center Director shall report to the Court on the patient’s status, and make recommendations. Any authorization by the Court for continued participation by the patient in any authorized treatment programs may be extended, modified or discontinued at the end of the effective period with or without further hearings, as the Court may determine.

(d) Any treatment program approved by the Court under this section may be terminated by the Medical Director of the Delaware Psychiatric Center. When a treatment program is terminated earlier than its court-approved expiration date, the Medical Director shall immediately notify the Superior Court. The Superior Court shall, after giving appropriate notice, hear the matter and review the decision of the Medical Director. At such termination hearing, the patient shall have such rights as are provided for other hearings under this section, including the right to counsel, the right to present evidence and the right to cross-examine witnesses. Where the Medical Director’s decision to terminate is based upon the patient’s mental or psychological condition, the patient may be examined by an independent psychiatrist or other qualified expert; provided, however, that the termination hearing shall not be held until such examination has been finally concluded.

11 Del. C. 1953, §  403;  58 Del. Laws, c. 497, §  1;  63 Del. Laws, c. 428, §§  1-3;  65 Del. Laws, c. 90, §§  1, 2;  70 Del. Laws, c. 186, §  1;  70 Del. Laws, c. 550, §  1; 

(a) Whenever the court is satisfied, after hearing, that an accused person, because of mental illness or serious mental disorder, is unable to understand the nature of the proceedings against the accused, or to give evidence in the accused’s own defense or to instruct counsel on the accused’s own behalf, the court may order the accused person to be confined and treated in the Delaware Psychiatric Center until the accused person is capable of standing trial. However, upon motion of the defendant, the court may conduct a hearing to determine whether the State can make out a prima facie case against the defendant, and if the State fails to present sufficient evidence to constitute a prima facie case, the court shall dismiss the charge. This dismissal shall have the same effect as a judgment of acquittal.

(b) When the court finds that the defendant is capable of standing trial, the defendant may be tried in the ordinary way, but the court may make any adjustment in the sentence which is required in the interest of justice, including a remission of all or any part of the time spent in the Psychiatric Center.

11 Del. C. 1953, §  404;  58 Del. Laws, c. 497, §  1;  59 Del. Laws, c. 203, §  3;  70 Del. Laws, c. 186, §  1;  70 Del. Laws, c. 550, §  1;  78 Del. Laws, c. 224, §  5; 

(a) Whenever the court is satisfied that a prisoner has developed a mental illness after conviction but before sentencing so that the prisoner is unable understandingly to participate in the sentencing proceedings, and if the court is satisfied that a sentence of imprisonment may be appropriate, the court may order the prisoner to be confined and treated in the Delaware Psychiatric Center until the prisoner is capable of participating in the sentencing proceedings.

(b) When the court finds that the prisoner is capable of participating in the sentencing proceedings, the prisoner may be sentenced in the ordinary way, but the court may make any adjustment in the sentence which is required in the interest of justice, including a remission of all or any part of the time spent in the Psychiatric Center.

11 Del. C. 1953, §  405;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1;  70 Del. Laws, c. 550, §  1;  78 Del. Laws, c. 224, §§  6, 7; 

(a) Whenever in any case it appears to the Superior Court, upon information received from the Department of Health and Social Services, that a prisoner confined with the Department has developed a mental illness after conviction and sentence, the Court may appoint 2 reputable practicing physicians to inquire of the mental condition of the prisoner and make report of their finding to the Court within 2 days from the date of their appointment, by writing under their hands and seals. Should the report of the physicians be that the prisoner has a mental illness, the prisoner shall at once be ordered by the Court transferred from the prison facility where the prisoner is confined to the Delaware Psychiatric Center.

(b) The expenses of the removal of such a person with a mental illness and of admission into such Psychiatric Center and maintenance therein up and until the time the person is discharged by the Court shall be borne by the State. If any such person with a mental illness has any real or personal estate, the Department of Health and Social Services shall have for the expenses and charges so incurred the same remedy as is provided in § 5019 of Title 16.

11 Del. C. 1953, §  406;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1;  70 Del. Laws, c. 550, §  1;  78 Del. Laws, c. 224, §  8;  79 Del. Laws, c. 442, §  2;  81 Del. Laws, c. 79, § 8; 

(a) Where a defendant’s defense is based upon allegations which, if true, would be grounds for a verdict of “guilty, but mentally ill” or the defendant desires to enter a plea to that effect, no finding of “guilty, but mentally ill” shall be rendered until the trier of fact has examined all appropriate reports (including the presentence investigation); has held a hearing on the sole issue of the defendant’s mental illness, at which either party may present evidence; and is satisfied that the defendant did in fact have a mental illness at the time of the offense to which the plea is entered. Where the trier of fact, after such hearing, is not satisfied that the defendant had a mental illness at the time of the offense, or determines that the facts do not support a “guilty, but mentally ill” plea, the trier of fact shall strike such plea, or permit such plea to be withdrawn by the defendant. A defendant whose plea is not accepted by the trier of fact shall be entitled to a jury trial, except that if a defendant subsequently waives the right to a jury trial, the judge who presided at the hearing on mental illness shall not preside at the trial.

(b) In a trial under this section a defendant found guilty but mentally ill, or whose plea to that effect is accepted, may have any sentence imposed which may lawfully be imposed upon any defendant for the same offense. Such defendant shall be committed into the custody of the Department of Correction, and shall undergo such further evaluation and be given such immediate and temporary treatment as is psychiatrically indicated. The Commissioner shall retain exclusive jurisdiction over such person in all matters relating to security. The Commissioner shall thereupon confine such person in the Delaware Psychiatric Center, or other suitable place for the residential treatment of criminally culpable persons with a mental illness under the age of 18 who have been found nonamenable to the processes of Family Court. Although such person shall remain under the jurisdiction of the Department of Correction, decisions directly related to treatment for the mental illness for individuals placed at the Delaware Psychiatric Center, shall be the joint responsibility of the Director of the Division of Substance Abuse and Mental Health and those persons at the Delaware Psychiatric Center who are directly responsible for such treatment. The Delaware Psychiatric Center, or any other residential treatment facility to which the defendant is committed by the Commissioner, shall have the authority to discharge the defendant from the facility and return the defendant to the physical custody of the Commissioner whenever the facility believes that such a discharge is in the best interests of the defendant. The offender may, by written statement, refuse to take any drugs which are prescribed for treatment of the offender’s mental illness; except when such a refusal will endanger the life of the offender, or the lives or property of other persons with whom the offender has contact.

(c) When the Psychiatric Center or other treating facility designated by the Commissioner discharges an offender prior to the expiration of such person’s sentence, the treating facility shall transmit to the Commissioner and to the Parole Board a report on the condition of the offender which contains the clinical facts; the diagnosis; the course of treatment, and prognosis for the remission of symptoms; the potential for the recidivism, and for danger to the offender’s own person or the public; and recommendations for future treatment. Where an offender under this section is sentenced to the Psychiatric Center or other facility, the offender shall not be eligible for any privileges not permitted in writing by the Commissioner (including escorted or unescorted on-grounds or off-grounds privileges) until the offender has become eligible for parole. Where the court finds that the offender, before completing the sentence, no longer needs nor could benefit from treatment for the offender’s mental illness, the offender shall be remanded to the Department of Correction. The offender shall have credited toward the sentence the time served at the Psychiatric Center or other facility.

(d) No individual under the age of 18 shall be placed at the Delaware Psychiatric Center. Nothing herein shall prevent either the transfer to or placement at the Delaware Psychiatric Center any person who has reached the age of 18 following any finding of guilty, but mentally ill.

63 Del. Laws, c. 328, §  2;  64 Del. Laws, c. 467, §  8;  70 Del. Laws, c. 186, §  1;  70 Del. Laws, c. 550, §  1;  73 Del. Laws, c. 41, §  1;  76 Del. Laws, c. 322, §§  1-3;  78 Del. Laws, c. 224, §  9;  79 Del. Laws, c. 371, §  9; 

(a) A person who has been adjudged “guilty, but mentally ill” and who during incarceration is discharged from treatment may be placed on prerelease or parole status under the same terms and laws applicable to any other offender. Psychological or psychiatric counseling and treatment may be required as a condition for such status. Failure to continue treatment, except by agreement of the Department of Correction, shall be a basis for terminating prerelease status or instituting parole violation hearings.

(b) If the report of the Delaware Psychiatric Center or other facility recommends parole, the paroling authority shall within 45 days or at the expiration of the offender’s minimum sentence, whichever is later, meet to consider the offender’s request for parole. If the report does not recommend parole, but other laws or administrative rules of the Department permit parole, the paroling authority may meet to consider a parole request. When the paroling authority considers the offender for parole, it shall consult with the State Hospital or other facility at which the offender had been treated, or from which the offender has been discharged.

(c) If an offender who has been found “guilty, but mentally ill” is placed on probation, the court, upon recommendation by the Attorney General, shall make treatment a condition of probation. Reports as specified by the trial judge shall be filed with the probation officer, and the sentencing court. Treatment shall be provided by an agency of the State or, with the approval of the sentencing court and at individual expense, private agencies, private physicians or other mental health personnel.

63 Del. Laws, c. 328, §  2;  70 Del. Laws, c. 186, §  1;  70 Del. Laws, c. 550, §  1; 

The fact that a criminal act was committed while the person committing such act was in a state of intoxication, or was committed because of such intoxication, is no defense to any criminal charge if the intoxication was voluntary.

11 Del. C. 1953, §  421;  58 Del. Laws, c. 497, §  1;  59 Del. Laws, c. 103, §  1;  59 Del. Laws, c. 203, §  37;  60 Del. Laws, c. 680, §  1; 

Evidence of voluntary intoxication shall not be admissible for the purpose of proving the existence of mental illness, mental defect, serious mental disorder or psychiatric disorder within the meaning of § 401 of this title.

11 Del. C. 1953, §  422;  58 Del. Laws, c. 497, §  1;  71 Del. Laws, c. 153, §  1;  78 Del. Laws, c. 224, §  10; 

In any prosecution for an offense it is a defense that, as a result of intoxication which is not voluntary, the actor at the time of the conduct lacked substantial capacity to appreciate the wrongfulness of the conduct or to perform a material element of the offense, or lacked sufficient willpower to choose whether the person would do the act or refrain from doing it.

11 Del. C. 1953, §  423;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1; 

As used in §§ 421-423 of this title:

(1) “Intoxication” means the inability, resulting from the introduction of substances into the body, to exercise control over one’s mental faculties.

(2) “Voluntary intoxication” means intoxication caused by substances which the actor knowingly introduces into the actor’s body, the tendency of which to cause intoxication the actor knows or should know, unless the actor introduces them pursuant to medical advice or under such duress as would afford a defense to a prosecution for a criminal offense.

11 Del. C. 1953, §  424;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1; 

(a) In any prosecution for an offense, it is an affirmative defense that the defendant engaged in the conduct charged to constitute the offense because the defendant was coerced to do so by the use of, or a threat to use, force against the defendant’s person or the person of another, which a reasonable person in the defendant’s situation would have been unable to resist.

(b) The defense provided by subsection (a) of this section is unavailable if the defendant intentionally or recklessly placed himself or herself in a situation in which it was probable that the defendant would be subjected to duress.

(c) It is not a defense that a woman acted on the command of her husband, unless she acted under such coercion as would establish a defense under this section. The presumption that a woman acting in the presence of her husband is coerced is abolished.

11 Del. C. 1953, §  431;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1; 

(a) In any prosecution for an offense, it is an affirmative defense that the accused engaged in the proscribed conduct because the accused was induced by a law-enforcement official or the law-enforcement official’s agent who is acting in the knowing cooperation with such an official to engage in the proscribed conduct constituting such conduct which is a crime when such person is not otherwise disposed to do so. The defense of entrapment as defined by this Criminal Code concedes the commission of the act charged but claims that it should not be punished because of the wrongdoing of the officer originates the idea of the crime and then induces the other person to engage in conduct constituting such a crime when the other person is not otherwise disposed to do so.

(b) The defense afforded by subsection (a) of this section is unavailable when causing or threatening physical injury is an element of the offense charged and the prosecution is based on conduct causing or threatening such injury to a person other than the person perpetrating the entrapment.

11 Del. C. 1953, §  432;  58 Del. Laws, c. 497, §  1;  59 Del. Laws, c. 203, §  38;  70 Del. Laws, c. 186, §  1; 

In any prosecution for an offense, it is a defense that the accused engaged in the conduct charged to constitute the offense under ignorance or mistake of fact if:

(1) The ignorance or mistake negatives the state of mind for the commission of the offense; or

(2) The statute defining the offense or a statute related thereto expressly provides that the ignorance or mistake constitutes a defense or exemption; or

(3) The ignorance or mistake is of a kind that supports a defense of justification as defined in this Criminal Code.

11 Del. C. 1953, §  441;  58 Del. Laws, c. 497, §  1; 

In any prosecution for an offense, it is a defense that the victim consented to the act done, provided that:

(1) The act did not involve or threaten physical injury; and

(2) Such consent negatives an element of the offense.

Any person who enters the presence of other people consents to the normal physical contacts incident to such presence.

11 Del. C. 1953, §  451;  58 Del. Laws, c. 497, §  1; 

In any prosecution for an offense involving or threatening physical injury, it is a defense that the victim consented to the infliction of physical injury of the kind done or threatened, provided that:

(1) The physical injury done or threatened by the conduct consented to is not serious physical injury; or

(2) The physical injury done or threatened is a reasonably foreseeable hazard of joint participation in any concerted activity, athletic contest or sport not prohibited by law.

11 Del. C. 1953, §  452;  58 Del. Laws, c. 497, §  1; 

Unless otherwise provided by this Criminal Code or by the law defining the offense, consent of the victim does not constitute a defense if:

(1) It is given by a person who is legally incompetent to authorize the conduct charged to constitute the offense unless the defendant believes the victim is legally competent; or

(2) It is given by a person who, because of youth, mental illness, mental condition, mental defect, serious mental disorder, psychiatric disorder or intoxication is manifestly unable or known by the defendant to be unable to make a reasonable judgment as to the nature or harmfulness of the conduct charged to constitute the offense; or

(3) It is given by a person whose improvident consent is sought to be prevented by the law defining the offense; or

(4) It is induced by force, duress or deception.

11 Del. C. 1953, §  453;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1;  78 Del. Laws, c. 224, §  11; 

Notwithstanding any provision of law to the contrary, it is no defense for an offense or sentencing provision defined in this title or in Title 16 or 31 which has as an element of such offense or sentencing provision the age of the victim that the accused did not know the age of the victim or reasonably believed the person to be of an age which would not meet the element of such offense or sentencing provision unless the statute defining such offense or sentencing provision or a statute directly related thereto expressly provides that knowledge of the victim’s age is an element of the offense or that lack of such knowledge is a defense.

73 Del. Laws, c. 126, §  2; 

In any prosecution for an offense, justification, as defined in §§ 462-471 of this title, is a defense.

11 Del. C. 1953, §  461;  58 Del. Laws, c. 497, §  1; 

(a) Unless inconsistent with the ensuing sections of this Criminal Code defining justifiable use of physical force, or with some other provision of law, conduct which would otherwise constitute an offense is justifiable when it is required or authorized by a provision of law or by a judicial decree, including:

(1) Laws defining duties and functions of public officers;

(2) Laws defining duties of private citizens to assist public servants in the performance of certain of their functions;

(3) Laws governing the execution of legal process;

(4) Laws governing the military services and the conduct of war; and

(5) Judgments or orders of competent courts or tribunals.

(b) The justification afforded by subsection (a) of this section applies when:

(1) The defendant’s conduct is required or authorized by the judgment or order of a competent court or tribunal or in the lawful execution of legal process, notwithstanding lack of jurisdiction of the court or defect in the legal process; or

(2) The defendant believes the conduct to be required or authorized to assist a public officer in the performance of the officer’s duties, notwithstanding that the officer exceeded the officer’s legal authority.

11 Del. C. 1953, §  462;  58 Del. Laws, c. 497, §  1;  59 Del. Laws, c. 203, §  4;  70 Del. Laws, c. 186, §  1; 

Unless inconsistent with the ensuing sections of this Criminal Code defining justifiable use of physical force, or with some other provisions of law, conduct which would otherwise constitute an offense is justifiable when it is necessary as an emergency measure to avoid an imminent public or private injury which is about to occur by reason of a situation occasioned or developed through no fault of the defendant, and which is of such gravity that, according to ordinary standards of intelligence and morality, the desirability and urgency of avoiding such injury clearly outweigh the desirability of avoiding the injury sought to be prevented by the statute defining the offense in issue. The necessity and justifiability of such conduct may not rest upon considerations pertaining only to the morality and advisability of the statute, either in its general application or with respect to its application to a particular class of cases arising thereunder.

11 Del. C. 1953, §  463;  58 Del. Laws, c. 497, §  1; 

(a) The use of force upon or toward another person is justifiable when the defendant reasonably believes that such force is immediately necessary for the purpose of protecting the defendant against the use of unlawful force by the other person on the present occasion.

(b) Except as otherwise provided in subsections (d) and (e) of this section, a person employing protective force may estimate the necessity thereof under the circumstances as the person reasonably believes them to be when the force is used, without retreating, surrendering possession, doing any other act which the person has no legal duty to do or abstaining from any lawful action.

(c) The use of deadly force is justifiable under this section if the defendant reasonably believes that such force is necessary to protect the defendant against death, serious physical injury, kidnapping or sexual intercourse compelled by force or threat.

(d) The use of force is not justifiable under this section to resist an arrest which the defendant knows or should know is being made by a peace officer, whether or not the arrest is lawful.

(e) The use of deadly force is not justifiable under this section if:

(1) The defendant, with the purpose of causing death or serious physical injury, provoked the use of force against the defendant in the same encounter; or

(2) The defendant knows that the necessity of using deadly force can be avoided with complete safety by retreating, by surrendering possession of a thing to a person asserting a claim of right thereto or by complying with a demand that the defendant abstain from performing an act which the defendant is not legally obligated to perform except that:

a. The defendant is not obliged to retreat in or from the defendant’s dwelling; and

b. The defendant is not obliged to retreat in or from the defendant’s place of work, unless the defendant was the initial aggressor; and

c. A public officer justified in using force in the performance of the officer’s duties, or a person justified in using force in assisting an officer or a person justified in using force in making an arrest or preventing an escape, need not desist from efforts to perform the duty or make the arrest or prevent the escape because of resistance or threatened resistance by or on behalf of the person against whom the action is directed.

11 Del. C. 1953, §  464;  58 Del. Laws, c. 497, §  1;  59 Del. Laws, c. 203, §  5;  70 Del. Laws, c. 186, §  1;  83 Del. Laws, c. 73, § 1; 

(a) The use of force upon or toward the person of another is justifiable to protect a third person when:

(1) The defendant would have been justified under § 464 of this title in using such force to protect the defendant against the injury the defendant reasonably believes to be threatened to the person whom the defendant seeks to protect; and

(2) Under the circumstances as the defendant reasonably believes them to be, the person whom the defendant seeks to protect would have been justified in using such protective force; and

(3) The defendant reasonably believes that intervention is necessary for the protection of the other person.

(b) Although the defendant would have been obliged under § 464 of this title to retreat, to surrender the possession of a thing or to comply with a demand before using force in self-protection, there is no obligation to do so before using force for the protection of another person, unless the defendant knows that the defendant can thereby secure the complete safety of the other person.

(c) When the person whom the defendant seeks to protect would have been obliged under § 464 of this title to retreat, to surrender the possession of a thing or to comply with a demand if the person knew that the person could obtain complete safety by so doing, the defendant is obliged to try to cause the person to do so before using force in the person’s protection if the actor knows that complete safety can be secured in that way.

(d) Neither the defendant nor the person whom the defendant seeks to protect is obliged to retreat when in the other’s dwelling or place of work to any greater extent than in their own.

11 Del. C. 1953, §  465;  58 Del. Laws, c. 497, §  1;  70 Del. Laws, c. 186, §  1;  83 Del. Laws, c. 73, § 2; 

(a) The use of force upon or toward the person of another is justifiable when the defendant reasonably believes that such force is immediately necessary:

(1) To prevent the commission of criminal trespass or burglary in a building or upon real property in the defendant’s possession or in the possession of another person for whose protection the defendant acts; or

(2) To prevent entry upon real property in the defendant’s possession or in the possession of another person for whose protection the defendant acts; or

(3) To prevent theft, criminal mischief or any trespassory taking of tangible, movable property in the defendant’s possession or in the possession of another person for whose protection the defendant acts.

(b) The defendant may in the circumstances named in subsection (a) of this section use such force as the defendant reasonably believes is necessary to protect the threatened property, provided that the defendant first requests the person against whom force is used to desist from interference with the property, unless the defendant reasonably believes that:

(1) Such a request would be useless; or

(2) It would be dangerous to the defendant or another person to make the request; or

(3) Substantial harm would be done to the physical condition of the property which is sought to be protected before the request could effectively be made.

(c) The use of deadly force for the protection of property is justifiable only if the defendant reasonably believes that:

(1) The person against whom the force is used is attempting to dispossess the defendant of the defendant’s dwelling otherwise than under a claim of right to its possession; or

(2) The person against whom the deadly force is used is attempting to commit arson, burglary, robbery or felonious theft or property destruction and either:

63 Del. Laws, c. 276, §  1;  70 Del. Laws, c. 186, §  1; 

(a) When the defendant reasonably believes that the use of force upon or toward the person of another is necessary for any of the purposes for which such relief would establish a justification under § § 462-468 of this title but the defendant is reckless or negligent in having such belief or in acquiring or failing to acquire any knowledge or belief which is material to the justifiability of the use of force, the justification afforded by those sections is unavailable in a prosecution for an offense for which recklessness or negligence, as the case may be, suffices to establish culpability.

(b) When the defendant is justified under §§ 462-468 of this title in using force upon or toward the person of another but the defendant recklessly or negligently injures or creates a risk of injury to innocent persons, the justification afforded by those sections is unavailable in a prosecution for an offense involving recklessness or negligence towards innocent persons.

11 Del. C. 1953, §  469;  58 Del. Laws, c. 497, §  1;  63 Del. Laws, c. 276, §  1;  70 Del. Laws, c. 186, §  1;  83 Del. Laws, c. 73, § 6; 

(a) “Deadly force” means force which the defendant uses with the purpose of causing or which the defendant knows creates a substantial risk of causing death or serious physical injury, including the use of a chokehold as “chokehold” is defined under § 607A of this title. Purposely firing a firearm in the direction of another person or at a vehicle 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 defendant’s purpose is limited to creating an apprehension that deadly force will be used if necessary, does not constitute deadly force.

(b) “Dwelling” means any building or structure, though movable or temporary, or a portion thereof, which is for the time being the defendant’s home or place of lodging.

(c) “Force,” in addition to its ordinary meaning, includes confinement.

(d) “Physical force” means force used upon or directed toward the body of another person.

(e) (1) “Reasonably believes,” when applied to a defendant who is not a law-enforcement officer acting in the officer’s official capacity, means holds a belief that is reasonable from the viewpoint of a reasonable person in the defendant’s situation under the circumstances.

(2) “Reasonably believes,” when applied to a defendant who is a law-enforcement officer acting in the officer’s official capacity, means holds a belief that is reasonable from the viewpoint of a reasonable law-enforcement officer in the defendant’s situation under the circumstances.

(f) “Unlawful force” means force 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) Notwithstanding any other provision of this Criminal Code, in any prosecution or sentencing for an offense, for the purposes of determining whether there is a reasonable explanation or excuse for the existence of extreme emotional disturbance or other asserted mitigating factor or circumstance, such explanation or excuse is not reasonable if it is based on the discovery of, knowledge or belief about, or the potential or actual disclosure of the victim’s actual or perceived sexual orientation, sex, gender, gender identity, or sex assigned at birth.

(c) Notwithstanding any other provision of this Criminal Code, in any prosecution or sentencing for an offense, a defendant does not suffer from a mental illness, mental defect, mental disorder, serious mental disorder, psychiatric disorder, or other impairment affecting or impacting the defendant’s mental state relating to any questions of intent; knowledge; capacity to appreciate the wrongfulness of the defendant’s conduct; disturbance of the defendant’s thinking, feeling, or behavior; culpability; willpower to choose whether to do or refrain from doing an act; or ability to distinguish right from wrong, based on the discovery of, knowledge or belief about, or the potential or actual disclosure of the victim’s actual or perceived sexual orientation, sex, gender, gender identity, or sex assigned at birth.

84 Del. Laws, c. 215, § 2; 

In any prosecution for an offense, it is an affirmative defense that the accused was granted immunity from prosecution for that offense by the Attorney General or a Deputy Attorney General or by court order pursuant to § 3506 of this title. It is also an affirmative defense that the accused was granted immunity from prosecution for a different offense when prosecution for the offense now charged would have been barred by prosecution for the offense as to which immunity was granted under § 208 of this title; provided, that the Attorney General or a Deputy Attorney General may, in granting immunity, stipulate that the immunity applies only to a specific offense, in which case effect shall be given to the stipulation.

11 Del. C. 1953, §  475;  58 Del. Laws, c. 497, §  1;  63 Del. Laws, c. 271, §  1;  70 Del. Laws, c. 186, §  1; 

(a) In any prosecution under Chapter 15 of this title where it is alleged that the offender or offenders were acting as members of a group or informal organization it shall be no defense to such prosecution or were engaged in any form of racketeering or racketeering activity, that:

(1) One or more members of the group or organization are not criminally responsible for the offense for which the prosecution is brought;

(2) One or more members of the group or organization have been acquitted, have not been prosecuted or convicted, have been convicted of a different offense or are immune from prosecution;

(3) A different person has been charged with, acquitted or convicted of any offense set forth in Chapter 15 of this title.

(b) Once an act of racketeering has been initiated by a group and there is a subsequent change in the number or identity of persons in such group or organization, as long as 2 or more of the original members remain in such group or are involved in a continuing course of conduct constituting an offense under Chapter 15 of this title, it shall be no defense to claim that the defendant was not part of the group or organization.

65 Del. Laws, c. 493, §  2;  70 Del. Laws, c. 186, §  1; 

(a) It is an affirmative defense to a prosecution under § 1503 of this title, that under circumstances manifesting a voluntary and complete renunciation of the criminal objective, the defendant withdrew from the proposed or intended unlawful activity before the commission of an offense set forth in Chapter 15 of this title; and that such person took further affirmative action that, in whole or in part, prevented the commission of the offense.

(b) Renunciation is not “voluntary,” if it is motivated in whole or in part:

(1) By circumstances not present or apparent at the inception of the defendant’s course of conduct that increased the probability of detection or apprehension, or that made more difficult the accomplishment of the objective; or

(2) By a decision to postpone the criminal conduct until another time, or to transfer the criminal act to another (but similar) objective or victim.

(c) Evidence that the defendant withdrew from the unlawful activity before commission of an offense set forth in Chapter 15 of this title, and made substantial effort to prevent the commission of an offense under that chapter, shall be admissible as mitigation at the hearing on punishment if such person has been found guilty; and in the event of a finding of renunciation under this section, the punishment of such person shall be less than that which would otherwise be imposed. The Court shall determine the extent and genuineness of the renunciation, and determine the reduction.
