Del. Super. Ct. Crim. R. 11

(a) Alternatives.

(1) In general. A defendant may plead not guilty, guilty, nolo contendere, or guilty but mentally ill. If

a defendant refuses to plead or if a defendant corporation fails to appear, the court shall enter a plea of

not guilty.

(2) Conditional pleas. [Omitted].

(b) Nolo contendere; guilty without admission. A defendant may plead nolo contendere or guilty without

admitting the essential facts constituting the offense charged only with the consent of the court. Such a

plea shall be accepted by the court only after due consideration of the views of the parties and the interest

of the public in the effective administration of justice.

(c) Advice to defendant. No plea of guilty or nolo contendere shall be accepted to a class B misdemeanor,

an unclassified misdemeanor or a violation for which no sentence of imprisonment will be imposed unless

the court is satisfied that the defendant understands the nature of the charge and the maximum possible

penalty provided by law. Before accepting a plea of guilty or nolo contendere to a felony or a class A

misdemeanor, or to any other offense for which a sentence of imprisonment will be imposed, the court

must address the defendant personally in open court and inform the defendant of, and determine that the

defendant understands, the following:

(1) The nature of the charge to which the plea is offered, the mandatory minimum penalty provided

by law, if any, and the maximum possible penalty provided by law, the fact that the court is required

to consider any applicable sentencing guidelines but may depart from those guidelines under some

circumstances, and, when applicable, that the court may also order the defendant to make restitution

to any victim of the offense; and

(2) If the defendant is not represented by an attorney, that the defendant has the right to be

represented by an attorney at every stage of the proceeding and, if necessary, one will be appointed to

represent the defendant; and

(3) That the defendant has the right to plead not guilty or to persist in that plea if it has already been

made, the right to be tried by a jury, when applicable, and at trial the right to the assistance of

counsel, the right to confront and cross-examine adverse witnesses, and the right against compelled

self-incrimination; and

(4) That if a plea of guilty or nolo contendere is accepted by the court there will not be a further trial

of any kind, so that by pleading guilty or nolo contendere the defendant waives the right to a trial; and

(5) If the court intends to question the defendant under oath, on the record, and in the presence of

counsel about the offense to which the defendant has pleaded, that the defendant’s answers may later

be used against the defendant in a prosecution for perjury or false statement.

(d) Insuring that the plea is voluntary. The court shall not accept a plea of guilty or nolo contendere

without first, by addressing the defendant personally in open court, determining that the plea is voluntary

and not the result of force or threats or of promises apart from a plea agreement. The court shall also

inquire as to whether the defendant’s willingness to plead guilty or nolo contendere results from prior

discussions between the attorney general and the defendant or the defendant’s attorney.

(e) Plea agreement procedure.

(1) In general. The attorney general and the attorney for the defendant or the defendant when acting

pro se may engage in discussions with a view toward reaching an agreement that, upon the entering of

a plea of guilty or nolo contendere to a charged offense or to a lesser or related offense, the attorney

general will do any of the following:

(A) File a dismissal of other charges; or

(B) Make a recommendation, or agree not to oppose the defendant’s request, for a particular

sentence, with the understanding that such recommendation or request shall not be binding upon

the court.

The prosecuting attorney shall comply with 11 Del. C. § 5106.

(2) Notice of such agreement. If a plea agreement has been reached by the parties, the court shall, on

the record, require the disclosure of the agreement in open court or, on a showing of good cause, in

camera, at the time the plea is offered. If the agreement is of the type specified in subdivision

(e)(1)(B), the court shall advise the defendant that if the court does not accept the recommendation or

request the defendant nevertheless has no right to withdraw the plea.

(3) Time of plea agreement procedure. Except for good cause shown, notification to the court of the

existence of a plea agreement shall be given at the arraignment or at such other time, prior to trial, as

may be fixed by the court.

(4) Inadmissibility of pleas, plea discussions, and related statements. Except as otherwise provided in

this paragraph, evidence of the following is not, in any civil or criminal proceeding, admissible

against the defendant who made the plea or was a participant in the plea discussions:

(A) A plea of guilty which was later withdrawn;

(B) A plea of nolo contendere;

(C) Any statement made in the course of any proceedings under this rule regarding either of the

foregoing pleas; or

(D) Any statement made in the course of plea discussions with the attorney general which do not

result in a plea of guilty or which result in a plea of guilty later withdrawn.

However, a judgment of conviction upon a plea of guilty or nolo contendere may be admissible in any

proceeding, and a statement under (C) or (D) of this paragraph is admissible (i) in any proceeding

wherein another statement made in the course of the same plea or plea discussions has been

introduced and the statement ought in fairness be considered contemporaneously with it, or (ii) in a

criminal proceeding for perjury or false statement if the statement was made by the defendant under

oath, on the record, and in the presence of counsel.

(f) Determining accuracy of plea. Notwithstanding the acceptance of a plea of guilty or nolo contendere,

the court should not enter a judgment upon such plea without making such inquiry as shall satisfy it that

there is a factual basis for the judgment.

(g) Record of proceedings. A verbatim record of the proceedings at which the defendant enters a plea

shall be made and, if there is a plea of guilty or nolo contendere, the record shall include, without

limitation, the court’s advice to the defendant, the inquiry into the voluntariness of the plea including any

plea agreement, and the inquiry into the accuracy of a guilty plea. The record shall also include a

completed and executed plea agreement and a completed and executed waiver of rights on forms

approved by the court.

(h) Harmless error. Any variance from the procedures required by this rule which does not affect

substantial rights shall be disregarded.

(i) Guilty but mentally ill. A plea of guilty but mentally ill shall be accepted when the requirements of this

rule applicable to a plea of guilty are met and the court finds that the defendant was mentally ill at the

time of the offense, in accordance with 11 Del. C. § 408.
