If the state redacts personal identifying information under this subparagraph of the Rule, the defendant may file a motion seeking disclosure of the redacted information. Should the court find good cause for disclosure, it shall order the state to provide the redacted information subject to any condition that it deems necessary to the orderly adjudication of the case or to the fair administration of justice.

The state may designate, and the court may order, evidence or material disclosed under this Rule as "Restricted Dissemination Material" by prominently stamping or otherwise marking such items as "Restricted Dissemination Material."(A)Designation. The state may designate any evidence or material subject to disclosure pursuant to this Rule as "Restricted Dissemination Material," without supporting certification, if the defendant agrees to the designation. In the absence of an agreement by the defendant, the state may designate any evidence or material as "Restricted Dissemination Material" by stamping or otherwise marking it as such and providing a certification in writing, upon information and belief, that: (i) the designated material relates to the statement of a child victim or witness; or (ii) there is a reasonable probability that disclosure of the designated material will result in (a) danger to the safety or security of a witness or victim, (b) danger of a witness being intimidated or tampered with, or (c) compromising an ongoing criminal investigation or confidential law enforcement technique.(B) Except as otherwise provided by order of the court or these Rules, "Restricted Dissemination Material" may only be disclosed to the defendant's attorney, the agents, or employees of the defendant's attorney, or to an expert witness who shall be advised of the designation associated with the material. The defendant's attorney may orally communicate the content of "Restricted Dissemination Material" to the defendant or allow the defendant to view the content of such material but shall not provide the defendant with copies of material so designated. If the defendant's attorney chooses to communicate or show the content of "Restricted Dissemination Material" to the defendant, the defense attorney shall not communicate or show the name of any victim or witness, date of birth, the residential address, telephone number, email address and place of employment of any witness or victim, or any other identifying information pertaining to the witness or victim or member of a witness's or victim's family. "Restricted Dissemination Material" may not otherwise be reproduced, copied, or disseminated in any way.(C)Relief from Restriction. If the state designates evidence or material as "Restricted Dissemination Material" under subpart (c)(2)(A) of this Rule, the defendant may at any time file a motion seeking to remove that designation from such evidence or material. Should the court find good cause to remove the designation, it shall order that the evidence or material no longer be designated as "Restricted Dissemination Material," subject to any condition that it deems necessary to the orderly adjudication of the case or to the fair administration of justice.(D)Defendants not represented by Counsel. In any case in which the defendant is not represented by counsel, the state may file a motion seeking to limit the scope of discovery under this Rule.

If, before or during trial, a party discovers additional evidence or material previously requested or ordered that is subject to discovery or inspection under this Rule or that an additional notice must be made, such party shall promptly notify the other party or that other party's attorney or the court of the existence of the additional evidence or material and/or make such notice.(f)Protectiveand Disclosure Order(1) Upon the motion of either party and for good cause, the court may enter a protective or disclosure order as to the discovery or inspection required by this Rule. The court in its discretion may order any condition that it deems necessary to the orderly adjudication of the case or to the fair administration of justice. These conditions may include: (A) a requirement that the parties not disclose the contents of any material or evidence disclosed or discovered under this Rule in any public forum, including any website;(B) a requirement that the parties not disclose the contents of any material or evidence disclosed or discovered pursuant to this Rule to any third-party who is not an agent or employee of the parties or an expert witness;(C) authorization to either party to withhold the residential address, telephone number, email address or place of employment of any witness not otherwise covered by the terms of paragraphs (b), (c), or (d) of this Rule;(D) a requirement that either party disclose specified personal identifying information, including the name, date of birth, residential address, telephone number, email address and place of employment of any witness; or(E) authorization for either party in appropriate circumstances to withhold from disclosure or place additional restrictions on dissemination of information otherwise discoverable but not exculpatory.(2) A party who believes in good faith that the terms of a protective order entered by the court have been violated may move the court to enforce the order and to impose any necessary and appropriate sanction authorized by Delaware law.(g)Witness Interview as Alternative. If the state withholds a witness's name and/or contact information under paragraph (b) or (c) of this Rule, upon request of counsel for the defendant, it shall take reasonable steps to make that witness available to counsel for the defendant for a timely interview. In such case, disclosure of the witness's name or contact information to the defendant shall not be required.(h)Failure to Comply With a Request. If at any time during the course of the proceedings the court determines that a party has failed to comply with this Rule, the court may order such party to permit the discovery or inspection, grant a continuance, or prohibit the party from introducing evidence not disclosed, or it may enter such other order as it deems just under the circumstances. In determining an appropriate remedy, the court shall consider whether the party seeking a remedy moved to compel compliance with this Rule.(i)Procedure(1)Request. The defendant may serve a request under paragraph (b) of this Rule after preliminary hearing. The state may serve a request under paragraph (d) of this Rule after service on the attorney general of such request by the defendant or such other time as ordered by the court. The request of either party shall set forth the items sought with reasonable particularity and shall specify a reasonable time, place, and manner of compliance with the request.(2)Response.(A)Initial Response by the State. Except in those cases where the court has entered an order setting dates for responses under this Rule, the state shall serve an initial response within 45 days of the request. An initial response shall include statements by the defendant and co-defendant, investigative reports, and search warrants.(B)Supplemental Responses by the State. The state shall file a supplemental response, or specify any objection to any request, as soon as practicable. The response may specify a reasonable alternative time, place, and manner of compliance without undue delay.

The defendant shall serve an initial response within 60 days of the state's request and any supplemental response shall be provided without undue delay. Any response shall address specifically and accurately each of the state's discovery requests.(3)Motion to Compel. If a party fails to comply with a request the opposing party may move for an order compelling compliance with the request. A motion to compel shall be filed within ten days after the time for response or at such other time as ordered by the court.(4)Service and Filing.(A) All requests for discovery under this Rule and responses thereto shall be served on other counsel or parties but shall not be filed with the court. In lieu thereof, the party requesting discovery and the party responding shall file with the court a "Notice of Service" certifying that a request or response was served and the date and manner of service. The party responsible for service shall retain custody of the original. In cases involving out-of-state counsel, Delaware counsel shall be the custodian. When a party uses any part of a request or response at trial or in proceedings on a motion, that party shall file it with the court. When a discovery request or anything produced in response to such a request is needed for any reason, the court, on its own motion, on motion by any party, or by stipulation of counsel, shall order the custodian to deliver it to the court. When a party files discovery material with the court other than during trial, the party shall file a notice stating, in no more than one page, the reason for filing the material and setting forth an itemized list thereof.(B) Service of requests and responses upon the defendant and the state may, in addition to the manner authorized by these rules, be made by electronic mail delivered to counsel of record.(5)Disclosure of Personal Identifying Information. Any disclosure of any personal identifying information of any victim or witness shall be minimized to include only that information consistent with the person's specific contact with the particular criminal matter and shall be provided in a manner demonstrating respect for the victim or witness's safety, dignity and privacy.De.
