    State v. Lixandra Hernandez and Jose G. Sanchez (A-39-14) (075444)
    Argued January 5, 2016 -- Decided June 28, 2016
    ALBIN, J., writing for a unanimous Court.
    In this appeal, the Court considers whether criminal defendants have a right to discovery of the files in
    unrelated cases involving the same cooperating witness.
    The State alleges that on three occasions in 2011, defendants sold more than five ounces of cocaine to a
    witness cooperating with law enforcement officials. Defendants were arrested a year after the last alleged
    transaction. In the interim, the cooperating witness (the Witness) assisted the State in a number of other drug
    investigations and prosecutions. The State provided discovery to defense counsel that included the name of the
    Witness, his criminal history, his cooperation and plea agreements with the State, and copies of audiotapes that
    allegedly contained the recordings of defendants’ transactions with the Witness. In exchange for his cooperation
    and guilty plea to racketeering, the State promised the Witness dismissal of the remaining gang-related criminal
    charges and a favorable sentence recommendation. The agreement also provides for sentence reductions for each
    successful prosecution of three targeted individuals on charges of leader of a narcotic trafficking network and each
    successful prosecution of two targeted individuals for distribution of PCP. The cooperation agreement will be void
    if the Witness knowingly provides false information, intentionally overstates or understates the involvement of other
    individuals in the targeted investigations, or should he be knowingly untruthful, false, incomplete or misleading in
    relation to those investigations.
    Defendants made discovery demands for information relating to the Witness’s cooperation with the State in
    other investigations and prosecutions. The State responded that the defense had not shown that the information was
    relevant. The trial court ordered the State to produce all of the documents in the unrelated investigations for an in
    camera review. During the hearing, defendants narrowed their discovery demand to: (1) statements of the
    cooperating witness and investigative reports in each matter identified by the State in which the witness provided
    information; (2) suStatmmaries of any interviews of the cooperating witness in any matter; (3) tape recordings and
    CDs of the cooperating witness; and (4) a privilege log of the internal memoranda and e-mails in this case and the
    three other Division of Criminal Justice investigations. The State objected, but complied with the court’s order. The
    court concluded that the information produced was not relevant or admissible in defendants’ case, but was
    discoverable because it might lead to relevant or admissible evidence. The State expressed its concern that the
    Witness could face retaliation if his identity were to be revealed to the targets of the unrelated investigations and
    invoked the informant’s privilege to attempt to shield his name from disclosure. The court did not find the
    informant’s privilege applicable and ruled that the documents in unrelated cases in which the Witness cooperated,
    would have to be tendered to the defense, unless the documents pertained to a pending investigation that had yet to
    result in an arrest or charge. The court ordered redactions of names and locations from disclosed documents and
    entered a protective order stating that the defense attorneys could not discuss the documents with anyone other than
    their clients. The State moved for leave to appeal and for a stay of the trial court’s discovery order.
    In an unpublished opinion, the appellate panel affirmed the trial court’s discovery order and rejected the
    State’s claim that the Witness was entitled to the protection of the informant’s privilege or that potential harm might
    come to the Witness by the disclosures. The Court granted the State’s motions for leave to appeal and for a stay
    pending appeal. 
    220 N.J. 564
    (2015).
    HELD: Although the discovery rule generally requires that the State provide all evidence relevant to the defense of
    criminal charges, it does not open the door to foraging through files of other cases in search of relevant evidence.
    The discovery ordered by the trial court and Appellate Division exceeds the limits of Rule 3:13-3(b) and is not
    supported by this Court’s jurisprudence.
    1. An accused has a right to broad discovery after the return of an indictment in a criminal case. Rule 3:13-3(b)
    states that discovery shall include exculpatory information and relevant material. Discovery in a criminal case is
    appropriate if it will lead to relevant information. Evidence is relevant if it has a tendency in reason to prove or
    disprove any fact of consequence to the determination of the action. The State’s discovery obligation also extends to
    providing material evidence affecting the credibility of a State’s witness whose testimony may be determinative of
    guilt or innocence. Thus, the State must disclose any promise of favorable treatment or leniency offered to a
    witness, including any plea or cooperation agreement setting forth the benefits to the witness. While discovery in
    criminal cases is broad, it is not unlimited. Nevertheless, trial courts are empowered to order discovery beyond that
    mandated by our court rules when doing so will further the truth-seeking function or ensure the fairness of a trial.
    However expansive the discovery rule and this Court’s jurisprudence may be, they do not sanction rummaging
    through irrelevant evidence. (pp. 14-17)
    2. Here, the State’s case is based on a cooperating witness who has given assistance to law enforcement in a number
    of criminal investigations. In discovery, the State has given the defense the Witness’s name, his statements to law
    enforcement authorities, his criminal history, his plea and cooperation agreements, audio recordings of the alleged
    drug transactions, the report of the forensic analysis of the cocaine allegedly sold by defendants, and investigative
    reports concerning the alleged offenses committed by defendants. In other words, the Attorney General has opened
    its investigative file in this case. The question, therefore, is whether defendants are entitled to open-file discovery of
    unrelated cases because the present case and the unrelated cases share a common thread -- the same cooperating
    witness. (pp. 18-19)
    3. Defendants have a right to expose the bias of the Witness for the purpose of undermining his credibility before the
    jury. Defendants can cross-examine the Witness on his expectation of favorable treatment for his cooperation and
    argue that he has sold his services and testimony to the State. The State has also opened the door to a line of
    questioning by giving itself wide discretion to void the cooperation agreement if the Witness should knowingly
    provide false information, answer any questions falsely, or intentionally overstate or understate the involvement of
    other individuals in the targeted investigations. Thus, defendant is entitled to information concerning any violation
    of the cooperation agreements, including disclosure of material false statements made by the witness and known to
    the State. Importantly, at oral argument before this Court, the State conceded that its discovery obligations required
    the disclosure of such material false statements. Defendants, however, do not want to rely on the State to turn over
    exculpatory information. They insist that they have the right under the discovery rules to sift through the files in the
    unrelated investigations in search of false and contradictory statements. At this stage, however, defendants have not
    articulated how the disclosure of documents in the unrelated investigations will lead to relevant or admissible
    evidence. (pp. 19-21)
    4. Defendants claim that they are entitled to false and inconsistent statements made by the Witness in the unrelated
    investigations. Such statements would not be admissible under N.J.R.E. 608 because evidence of specific instances
    of conduct -- other than a prior conviction -- to prove the character trait of untruthfulness is prohibited. This rule
    was designed to prevent unfair foraging into the witness’s past and to prevent wide-ranging collateral attacks on the
    general credibility of a witness that would cause confusion of the true issues in the case. Defendants also claim that
    documents in the unrelated investigations may be necessary to refresh the Witness’s recollection under N.J.R.E. 612,
    but such a vague discovery request is not tied to a specified demand for information that meets the threshold of
    relevance. Defendants further claim that discovery is necessary to uncover false criminal accusations against others
    that would be admissible under N.J.R.E. 608. However, defendants have not made any showing that the Witness
    has made false criminal accusations against others. An open-ended search of unrelated investigative files in the
    hope that something may turn up that has impeachment value is not sanctioned by the discovery rule or this Court’s
    jurisprudence. (pp. 21-22)
    5. The informant’s privilege permits a witness to refuse to disclose the identity of a confidential informant unless the
    judge finds that (a) the identity of the person furnishing the information has already been otherwise disclosed or (b)
    disclosure of his identity is essential to assure a fair determination of the issues. The State has legitimate concerns
    for the safety of witnesses. The disclosure of the Witness’s identity in this case is necessary because he will testify
    against defendants. The potential threat to his life, however, would increase exponentially if his identity were
    revealed to the targets in the unrelated drug investigations. At least at this stage, the disclosure of the Witness’s
    identity in the unrelated investigations is not necessary for defendants to receive a fair trial. If defendants cannot
    signify with some specificity the relevance of the requested documents -- as opposed to speculative relevance -- the
    balancing of probative value against the dangers of disclosure weighs in favor of not removing the Witness’s cover,
    at least until defendants can make some concrete showing of need. (pp. 23-24)
    The judgment of the Appellate Division is REVERSED. The discovery order is VACATED and the
    matter is REMANDED to the trial court for further proceedings consistent with this opinion.

    SUPREME COURT OF NEW JERSEY
    A-39 September Term 2014
    075444
    STATE OF NEW JERSEY,
    Plaintiff-Appellant,
    v.
    LIXANDRA HERNANDEZ and JOSE
    G. SANCHEZ,
    Defendants-Respondents.
    Argued January 5, 2016 – Decided June 28, 2016
    On appeal from the Superior Court, Appellate
    Division.
    Carol M. Henderson, Assistant Attorney
    General, argued the cause for appellant
    (John J. Hoffman, Acting Attorney General of
    New Jersey, attorney).
    Michael P. Koribanics and Charles J. Alvarez
    argued the cause for respondents (Koribanics
    & Koribanics, attorneys for Lixandra
    Hernandez and Peter R. Willis, attorney for
    Jose G. Sanchez).
    Lawrence S. Lustberg argued the cause for
    amicus curiae Association of Criminal
    Defense Lawyers of New Jersey (Gibbons,
    attorneys; Mr. Lustberg, Jillian T. Stein,
    and Laurie A. Kelly, on the brief).
    JUSTICE ALBIN delivered the opinion of the Court.
    New Jersey provides a broad range of discovery to an
    accused in a criminal case under Rule 3:13-3.   This open-file
    approach is intended to ensure fair and just trials.    Here, the
    1
    issue is not whether defendants have a right to discovery of the
    prosecutor’s file in their case, but whether they have a right
    to discovery of the files in unrelated cases involving the same
    cooperating witness.
    The cooperating witness (the Witness) in defendants’ drug
    case assisted the State in a number of drug investigations and
    prosecutions.   In discovery, defendants were given the
    agreements between the State and the Witness in this case and in
    unrelated cases, and the State has represented that it will
    provide the defense with any known material false statements
    made by the Witness in those cases.   Defendants nevertheless
    insist that they are entitled to every statement made by the
    Witness in each case in which he has cooperated with the State,
    whether those statements are contained in a transcribed
    interview, recorded drug transaction, investigative report, or
    memorandum between members of the prosecutorial team.
    The trial court determined that such information,
    regardless of its lack of relevance, is discoverable under our
    court rules.    The Appellate Division affirmed.
    We hold that the discovery ordered by the trial court and
    Appellate Division exceeds the limits of Rule 3:13-3(b) and is
    not supported by our jurisprudence.    Although our discovery rule
    generally requires that the State provide all evidence relevant
    to the defense of criminal charges, it does not open the door to
    2
    foraging through files of other cases in search of relevant
    evidence.   The only information discoverable in the unrelated
    cases that is relevant to the defense at this point are the
    cooperation agreements between the State and the Witness and any
    violations of the agreements, such as material false statements
    made by the Witness and known to the State.   The discovery order
    here requires disclosure of information not mandated by our
    discovery rule -- information that has no ostensible relevance
    to the case to be tried.
    Accordingly, we reverse the judgment of the Appellate
    Division and remand for proceedings consistent with this
    opinion.
    I.
    The Charges
    Defendants Lixandra Hernandez and Jose G. Sanchez are
    charged in a State Grand Jury indictment with second-degree
    conspiracy to distribute more than five ounces of cocaine,
    N.J.S.A. 2C:5-2; first-degree distribution of more than five
    ounces of cocaine, N.J.S.A. 2C:35-5(a)(1), (b)(1), (c), and
    N.J.S.A. 2C:2-6; second-degree distribution of cocaine within
    500 feet of a public park, N.J.S.A. 2C:35-7.1 and N.J.S.A. 2C:2-
    6; and third-degree possession of cocaine, N.J.S.A. 2C:35-
    10(a)(1) and N.J.S.A. 2C:2-6.
    3
    The State alleges that on November 28, December 1, and
    December 14, 2011, defendants sold, in all, more than five
    ounces of cocaine to the Witness cooperating with law
    enforcement officials.   The three controlled buys were audio-
    recorded.
    Defendants were not arrested until a year after the last
    alleged drug transaction.   In the interim, the Witness
    cooperated with the State in a number of other investigations.
    The State provided discovery to defense counsel that
    included the name of the Witness, his criminal history, his
    cooperation agreements and plea agreement with the State, and
    copies of audiotapes that allegedly contained the recordings of
    defendants’ transactions with the Witness.   The discovery
    revealed that the Witness had cooperated with the State in
    criminal investigations of a violent street gang.   In exchange
    for his cooperation and guilty plea to racketeering, the State
    promised the Witness dismissal of the remaining gang-related
    criminal charges and a favorable sentence recommendation.
    The Cooperation Agreement
    The State and the Witness entered into two cooperation
    agreements, but only the superseding agreement is germane to
    this case.   The superseding cooperation agreement sets forth the
    criminal charges filed against the Witness, including (1) first-
    degree racketeering; (2) second-degree conspiracy to commit
    4
    robbery, burglary, and possession of a firearm with the purpose
    to use it unlawfully against another; (3) third-degree receiving
    stolen property; and (4) two second-degree and three third-
    degree weapons offenses.   On the charge of racketeering alone,
    the Witness faced an extended term sentence of life imprisonment
    and exposure to mandatory consecutive sentences on other
    offenses, as well as application of the No Early Release Act
    (NERA), N.J.S.A. 2C:43-7.2.
    The superseding cooperation agreement enumerates a number
    of incentives for the Witness’s assistance.   The State has
    promised the Witness that if his cooperation is of “productive
    and of substantial value to the State . . . , the State will
    recommend a sentence of 14 years in State Prison subject to
    [NERA]” on the racketeering charge to which he pled guilty.1    The
    cooperation agreement also provides for further sentence
    reductions of eighteen months for each “successful prosecution”
    of three targeted individuals on charges of first-degree leader
    of a narcotic trafficking network, reductions of six months for
    each “successful prosecution” of two targeted individuals for
    first-degree distribution of PCP, and further sentence
    1 The Witness’s plea agreement with the State indicates that, in
    exchange for his plea of guilty to racketeering and conspiracy
    to commit robbery and burglary, the remaining charges will be
    dismissed. The cooperation agreement does not refer to a
    sentence recommendation on the conspiracy charge.
    5
    reductions for convictions of lesser offenses.       The State has
    further promised to amend the agreement to give the Witness
    credit for cooperation leading to the indictment of persons
    involved in other criminal schemes.
    The State makes clear that the cooperation agreement will
    be void if the Witness should “knowingly provide false
    information, answer any questions falsely . . . or intentionally
    overstate or understate the involvement of other individuals” in
    the targeted investigations, or should he “in any manner be
    knowingly untruthful, false, incomplete or misleading in
    relation” to those investigations.
    Discovery Issue
    Defendants made broad discovery demands for information
    relating to the Witness’s cooperation with the State in other
    investigations and prosecutions.       In a letter dated February 3,
    2014, the defense requested:
    1. All internal memorandum, emails, and
    interviews of [the Witness] by any member of
    law enforcement regarding all matters referred
    to in the cooperation agreements dated October
    26, 2011 and January 25, 2012.
    2. Notes and documentations of all contacts
    between and amongst [the Witness] and any
    member of law enforcement for the state of New
    Jersey.
    3. Any and all communications [including
    emails] from the attorney for [the Witness] to
    any member of law enforcement and/or the
    6
    Attorney General’s office regarding         his
    cooperation and/or plea agreement.
    4. Any and all statements [including emails]
    made in proffers or disclosures made by [the
    Witness] in furtherance of his cooperation
    agreement.
    5. Copies of any [and] all documents,
    including discovery in prior cases that were
    reviewed in connection with granting [the
    Witness] a cooperation agreement.
    The State responded that the defense had not made a showing
    that the information requested was relevant.   At a February 7,
    2014 discovery conference, the trial court ordered the State to
    produce all of the documents in the unrelated investigations for
    an in camera review and to prepare a privilege log.    The State
    indicated that the pretrial discovery in the unrelated cases in
    which the Witness had cooperated filled nine banker’s boxes.
    During the hearing, defendants narrowed their discovery demand
    to:
    1. Statements of the cooperating witness and
    investigative reports in the four matters
    identified by the State in which the witness
    provided information.
    2. Summaries of any interviews        of    the
    cooperating witness in any matter.
    3. Tape recordings and CDs of the cooperating
    witness.
    4. A privilege log of the internal memoranda
    and e-mails in this case and the three other
    Division of Criminal Justice investigations.
    7
    Although the State continued to object to the defense’s
    discovery demands, the State complied with the court’s order and
    provided for in camera review a number of documents, including
    investigative reports and intercepted telephone calls in
    unrelated matters in which the Witness had cooperated.     After
    completing the in camera document review, the court concluded
    that the information produced was not relevant or admissible in
    defendants’ case, but was discoverable, apparently based on the
    court’s belief -- though not stated explicitly -- that the
    information might lead to relevant or admissible evidence.     The
    State vigorously expressed its concern that the Witness could
    face retaliation or even death if his identity were to be
    revealed to the targets of the unrelated investigations.    The
    State invoked the informant’s privilege, N.J.R.E. 516, in an
    attempt to shield his name from disclosure.   The court did not
    find the informant’s privilege applicable.
    Ultimately, the court ruled that, notwithstanding their
    lack of relevance in the present matter, documents in unrelated
    cases in which the Witness cooperated would have to be tendered
    to the defense, unless the documents pertained to a pending
    investigation that had yet to result in an arrest or charge.
    However, in those cases in which the Witness cooperated and
    either no charges were filed or charges are pending against the
    targets of the investigation, or the targets entered guilty
    8
    pleas, the court ordered disclosure of documents to the defense.
    Those documents to be disclosed include investigative reports,
    the Witness’s statements and summaries of those statements,
    recordings of conversations between the Witness and
    investigative targets, and -- subject to the work-product
    privilege -- internal law enforcement emails mentioning the
    Witness and emails between the Witness’s attorney and law
    enforcement officials.2   In light of the potential threat to the
    Witness from those disclosures, the court ordered redactions of
    names and locations from disclosed documents.3   The court also
    entered a protective order stating that the defense attorneys
    could not discuss the documents “with anybody other than [their]
    clients.”
    A panel of the Appellate Division granted the State’s
    motions for leave to appeal and for a stay of the discovery
    order.
    2 The court indicated that relief would be granted to the State
    if the electronic email search became unduly burdensome.
    3 The signed discovery order entered by the trial court provides
    that “subject to the appropriate redactions and the entry of a
    Protective Order as set forth on the record February 10,
    2014[,]” “[t]he State must release documents and other materials
    in its possession related to [the Witness],” but not “documents
    or materials related . . . to ongoing investigations.” The
    February 10 record of the discovery proceeding is not a model of
    clarity. A written discovery order that is detailed and
    specific will assist not only the parties in understanding their
    respective obligations, but also appellate review.
    9
    II.
    In an unpublished opinion, the appellate panel affirmed the
    trial court’s discovery order.   In doing so, the panel noted
    that broad discovery is permitted under Rule 3:13-3 and that
    substantial deference must be paid to the trial court’s
    evidentiary rulings.   It observed that the discovery request was
    narrowed to “e-mails, the three other [Division of Criminal
    Justice] investigations, and statements and summaries involving
    [the Witness],” and “a privilege log detailing internal
    memoranda.”   The panel concluded that the “discovery is
    rationally related to defendants’ right to confront a key state
    witness as to potential bias, prejudice or motive and is
    relevant for that purpose.”   It rejected the State’s claim that
    the Witness was entitled to the protection of the informant’s
    privilege, N.J.R.E. 516, or that potential harm might come to
    the Witness by the disclosures, reasoning that the Witness’s
    “identifying information has already been provided in this case
    as well as in other criminal prosecutions.”   Last, the panel
    indicated that the “discovery order was tailored to [the
    Witness’s] involvement in other investigations referenced in the
    cooperation agreements” and that the “court stated if the
    electronic search produced thousands of documents the request
    would be narrowed.”
    10
    We granted the State’s motions for leave to appeal and for
    a stay pending appeal.   State v. Hernandez, 
    220 N.J. 564
    (2015).
    The Association of Criminal Defense Lawyers of New Jersey (ACDL)
    was granted leave to participate as amicus curiae before the
    Appellate Division, and therefore was permitted, “without
    seeking further leave,” to appear before this Court.     See R.
    1:13-9(d).
    III.
    A.
    The State argues that its use of a cooperating witness in
    this case is not a legitimate basis for ordering discovery of
    documents in unrelated investigations involving the Witness when
    the documents bear no relevance to the present case.     The State
    maintains that the trial court’s order is “an unprecedented
    expansion of the discovery rules,” allows the defense to go on a
    “fishing expedition,” and places on the Attorney General’s
    Office the burdensome task of creating a privilege log of every
    email communication or memorandum mentioning the cooperating
    witness.   According to the State, the trial court’s
    acknowledgment that the documents in the unrelated
    investigations are not relevant or admissible in this case is
    proof that the documents are not subject to discovery.    The
    State contends that it has satisfied its discovery obligations
    by providing the defense with all statements made by the Witness
    11
    in this case, the Witness’s criminal record, and cooperation
    agreements between the State and the Witness involving all
    investigations.   Those disclosures, the State asserts, allow
    defendants to explore the Witness’s favorable treatment and to
    expose potential bias.
    The State also submits that the cooperating witness’s name
    was not disclosed in unrelated investigations because some of
    those investigations did not result in the filing of charges,
    and, in others, because the cases were resolved without trials.
    The State claims that disclosure of the Witness’s identity in
    those unrelated cases unnecessarily subjects him to retaliation
    and potential harm.
    B.
    Defendants urge this Court to affirm the trial court’s
    discovery order, emphasizing that the issue at this point is not
    the admissibility of the documents in the unrelated
    investigations.   Defendants submit that the discovery order was
    “specifically tailored to identify material related to any
    benefits to be received by the cooperating witness.”     According
    to defendants, “each successive investigation mentioned in the
    cooperation agreement has a direct impact and influence on the
    value of any benefit [the Witness] will receive.”     Defendants
    also argue that the cooperation agreements give rise to the need
    for the documents so that the defense can explore any benefits
    12
    given to the Witness, N.J.R.E. 607, expose any inconsistent
    statements, N.J.R.E. 613, refresh the Witness’s recollection
    with a writing, N.J.R.E. 612, and probe the Witness’s character
    for truthfulness and for any false accusation he may have made,
    N.J.R.E. 608.   Finally, defendants contend that the State bears
    the burden of producing discovery in its possession, however
    onerous that may be, and that the documents ordered to be
    disclosed “are already available, and in some cases already
    organized.”
    C.
    Amicus curiae ACDL argues that upholding the discovery
    order in this case is particularly important because of
    empirical evidence and an “emerging consensus that the testimony
    of [cooperating witnesses], upon which so many convictions are
    based, is often unreliable, particularly in light of the
    promises of lenient treatment or compensation that these
    witnesses receive.”   It submits that the discovery order “was
    carefully tailored to provide important impeachment material but
    not to tread on ongoing State investigations.”   The ACDL posits
    that “the statements of a [cooperating witness] in other similar
    investigations . . . are . . . very likely to reveal exculpatory
    or impeachment evidence that will be crucial to the effective
    cross-examination of that witness.”   Additionally, the ACDL
    maintains that the court’s ordering of the redaction of names
    13
    and locations from documents in unrelated investigations in
    which the cooperating witness’s identity has not been revealed,
    and the entry of a protective order, address and mitigate any
    potential for reprisal against the Witness.
    IV.
    A.
    We accord substantial deference to a trial court’s issuance
    of a discovery order and will not interfere with such an order
    absent an abuse of discretion.   State ex rel. A.B., 
    219 N.J. 542
    , 554 (2014).   We need not defer, however, to a discovery
    order that is well “wide of the mark,” ibid., or “based on a
    mistaken understanding of the applicable law,”     Pomerantz Paper
    Corp. v. New Cmty. Corp., 
    207 N.J. 344
    , 371 (2011) (quoting
    Rivers v. LSC P’ship, 
    378 N.J. Super. 68
    , 80 (App. Div.),
    certif. denied, 
    185 N.J. 296
    (2005)).      Additionally, our review
    of the meaning or scope of a court rule is de novo, and
    therefore we owe no deference to the interpretative statements
    of the trial court and Appellate Division, unless they are
    persuasive in their reasoning.   See 
    A.B., supra
    , 219 N.J. at
    554-55.
    B.
    In New Jersey, an accused has a right to broad discovery
    after the return of an indictment in a criminal case.      State v.
    Scoles, 
    214 N.J. 236
    , 252 (2013).      This state’s “open-file
    14
    approach to pretrial discovery in criminal matters” is intended
    “[t]o advance the goal of providing fair and just criminal
    trials.”   
    Ibid. The metes and
    bounds of the State’s discovery
    obligation to the defense is found in Rule 3:13-3(b), which
    states that “[d]iscovery shall include exculpatory information
    or material” and “relevant material,” including all items set
    forth in ten separate categories.
    No one questions that discovery in a criminal case “is
    appropriate if it will lead to relevant” information.    State v.
    Ballard, 
    331 N.J. Super. 529
    , 538 (App. Div. 2000) (emphasis
    added).    But cf. R. 4:10-2(a) (stating that discovery in civil
    cases extends to information that “appears reasonably calculated
    to lead to the discovery of admissible evidence” (emphasis
    added)).   “Relevancy is the hallmark of admissibility of
    evidence.”   State v. Darby, 
    174 N.J. 509
    , 519 (2002).   Evidence
    is relevant if it “ha[s] a tendency in reason to prove or
    disprove any fact of consequence to the determination of the
    action.”   N.J.R.E. 401.
    Four categories of Rule 3:13-3(b), requiring the disclosure
    of relevant material to the defense, are directly germane to
    this case:
    (E) books, papers, documents, or copies
    thereof, or tangible objects, buildings or
    places which are within the possession,
    custody   or control  of   the  prosecutor,
    including, but not limited to, writings,
    15
    drawings, graphs, charts, photographs, video
    and sound recordings, images, electronically
    stored information, and any other data or data
    compilations stored in any medium from which
    information can be obtained and translated, if
    necessary, into reasonably usable form;
    (F) names, addresses, and birthdates of any
    persons whom the prosecutor knows to have
    relevant evidence or information including a
    designation by the prosecutor as to which of
    those persons may be called as witnesses;
    (G) record of statements, signed or unsigned,
    by such persons or by co-defendants which are
    within the possession, custody or control of
    the prosecutor and any relevant record of
    prior conviction of such persons. . . . ;
    (H) police reports that        are within   the
    possession, custody, or        control of   the
    prosecutor[.]
    [R. 3:13-3(b)(1)(E)-(H).]
    The State’s discovery obligation also extends to providing
    “material evidence affecting [the] credibility” of a State’s
    witness whose testimony may be determinative of guilt or
    innocence.   State v. Carter, 
    69 N.J. 420
    , 433 (1976) (citing
    Giglio v. United States, 
    405 U.S. 150
    , 
    92 S. Ct. 763
    , 
    31 L. Ed. 2d
    104 (1972)).   Thus, the State must disclose any promise of
    favorable treatment or leniency offered to a witness, including
    any plea or cooperation agreement setting forth the benefits to
    the witness.   See State v. Long, 
    119 N.J. 439
    , 489 (1990);
    
    Carter, supra
    , 69 N.J. at 429-30, 434.
    16
    While discovery in criminal cases is broad, it is not
    unlimited.   State v. D.R.H., 
    127 N.J. 249
    , 256 (1992).      “For
    example, defendants cannot transform the discovery process into
    an unfocused, haphazard search for evidence.”     Ibid.; see also
    State v. R.W., 
    104 N.J. 14
    , 28 (1986) (“[A]llowing a defendant
    to forage for evidence without a reasonable basis is not an
    ingredient of either due process or fundamental fairness in the
    administration of the criminal laws.”).    Nevertheless, “our
    trial courts are empowered to order discovery beyond that
    mandated by our court rules when doing so will further the
    truth-seeking function or ensure the fairness of a trial.”
    
    A.B., supra
    , 219 N.J. at 560.   In A.B., we upheld an order
    allowing the defense to inspect the alleged victim’s home, where
    an alleged sexual offense had occurred, even though the premises
    did “not fall within the general scope of the automatic
    discovery rule because her home [was] not ‘within the
    possession, custody or control of the prosecutor.’”        
    Id. at 556
    (quoting R. 3:13-3(b)(1)(E)).   We did so, notwithstanding the
    intrusion into the alleged victim’s privacy rights, because the
    inspection would lead to relevant evidence -- an understanding
    of the layout of the crime scene -- and was necessary to protect
    the juvenile’s right to a fair trial.     
    Id. at 556
    -62.     However
    expansive our discovery rule and jurisprudence may be, they do
    not sanction rummaging through irrelevant evidence.
    17
    V.
    A.
    We begin our analysis by indicating what is not at issue.
    The State has provided discovery directly related to the charges
    against defendants.   The State’s case is based on a cooperating
    witness who has given assistance to law enforcement in a number
    of criminal investigations.   In this matter, the Witness acted
    in the role of a drug buyer, making three alleged drug purchases
    from defendants that resulted in the charges enumerated in the
    indictment.   The Witness recorded each transaction.   At the time
    that the Witness played the role of drug buyer here, he had
    entered into a cooperation agreement with the State seeking
    favorable treatment for an array of offenses that he faced,
    including first-degree racketeering.   The Witness’s cooperation
    agreement details the charge and sentence reductions he will
    receive for his assistance to law enforcement in this case and
    in a number of other criminal investigations.   In at least some
    -- if not all -- of those other investigations, his identity
    still has not been disclosed to ensure his safety.4
    In discovery, the State has given the defense the Witness’s
    name, his statements to law enforcement authorities, his
    criminal history, his plea and cooperation agreements, audio
    4 The lack of specificity in the record prompts our caution in
    not making an unqualified assertion.
    18
    recordings of the alleged drug transactions, the report of the
    forensic analysis of the cocaine allegedly sold by defendants,
    and investigative reports concerning the alleged offenses
    committed by defendants.   See R. 3:13-3(b).   In other words, the
    Attorney General has opened its investigative file in this case.
    The question, therefore, is whether defendants are entitled to
    open-file discovery of unrelated cases because the present case
    and the unrelated cases share a common thread -- the same
    cooperating witness.
    B.
    Defendants have a right to expose the bias of the Witness -
    - the favorable treatment promised to him for his cooperation in
    this case and other investigations -- for the purpose of
    undermining his credibility before the jury.   Defendants were
    provided in discovery the plea and cooperation agreements, which
    detail the charge- and sentence-reduction incentives offered to
    the Witness if the State credits his cooperation in this case as
    of “productive and of substantial value” and if his cooperation
    leads to the “successful prosecution” of targeted individuals in
    other cases.   Defendants can cross-examine the Witness on his
    expectation of favorable treatment for his cooperation and argue
    that he has sold his services and testimony to the State.
    The State also has opened the door to a line of questioning
    by giving itself wide discretion to void the cooperation
    19
    agreement if the Witness should “knowingly provide false
    information, answer any questions falsely . . . or intentionally
    overstate or understate the involvement of other individuals” in
    the targeted investigations.    The State has the proverbial sword
    of Damocles hanging over the Witness’s head if he is untruthful.
    Clearly, if the Witness knowingly provided false or misleading
    information to the State in the other investigations and the
    State declined to void the agreement, the State’s failure to do
    so would be another benefit conferred on the Witness that must
    be disclosed in discovery.     In such a circumstance, defendants
    could argue that even when the Witness lies, he has a reasonable
    expectation that he will receive favorable treatment.
    Defendants have “a right to explore evidence tending to show
    that the State may have a ‘hold’ of some kind over a witness,
    the mere existence of which might prompt the individual to color
    his testimony in favor of the prosecution.”     State v. Bass, 
    224 N.J. 285
    , 302 (2016) (quoting State v. Parsons, 
    341 N.J. Super. 448
    , 458 (App. Div. 2001)).    Thus, defendant is entitled to
    information concerning any violation of the cooperation
    agreements, including disclosure of material false statements
    made by the witness and known to the State.     Importantly, at
    oral argument before this Court, the State conceded that its
    discovery obligations required the disclosure of such material
    false statements.
    20
    Defendants, however, do not want to rely on the kindness of
    the State to turn over exculpatory information.    They insist
    that they have the right under our discovery rules and Brady v.
    Maryland, 
    373 U.S. 83
    , 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d 215
    (1963),
    to sift through the files in the unrelated investigations --
    through the Witness’s statements, investigative reports and
    emails mentioning the Witness, and recorded conversations
    between the Witness and investigative targets in search of false
    and contradictory statements.5   Defendants want to undertake a
    speculative venture, hoping to snare some morsel of information
    that may be helpful to the defense.    At this stage, however,
    defendants have not articulated how the disclosure of documents
    in the unrelated investigations will lead to relevant or
    admissible evidence.    See 
    Ballard, supra
    , 331 N.J. Super. at
    538.
    Putting aside the issue of bias previously discussed,
    defendants claim that they are entitled to false and
    inconsistent statements made by the Witness in the unrelated
    5 In 
    Brady, supra
    , the United States Supreme Court held that due
    process forbids the government from withholding material
    evidence favorable to an accused that has been requested by the
    
    defense. 373 U.S. at 87
    , 83 S. Ct. at 
    1196-97, 10 L. Ed. 2d at 218
    . The disclosures required by Rule 3:13-3(b)(1), which
    include the release of exculpatory information or material and
    all other information relevant to a legitimate defense, are more
    expansive than the due process disclosures mandated by Brady and
    its progeny.
    21
    investigations.   But such statements would not be admissible
    under N.J.R.E. 608 because “evidence of specific instances of
    conduct -- other than a prior conviction -- to prove the
    character trait of untruthfulness is prohibited.”   State v.
    Guenther, 
    181 N.J. 129
    , 140 (2004).   This rule “was designed to
    prevent unfair foraging into the witness’s past” and to prevent
    “wide-ranging collateral attacks on the general credibility of a
    witness [that] would cause confusion of the true issues in the
    case.”   
    Id. at 141-42.
    Defendants also claim that documents in the unrelated
    investigations may be necessary to refresh the Witness’s
    recollection, N.J.R.E. 612, but such a vague discovery request
    is not tied to a specified demand for information that meets the
    threshold of relevance.   Defendants further claim that discovery
    is necessary to uncover false criminal accusations against
    others that would be admissible under N.J.R.E. 608.   In
    
    Guenther, supra
    , we held that “in limited circumstances and
    under very strict controls a defendant has the right to show
    that a victim-witness has made a prior false criminal accusation
    for the purpose of challenging that witness’s 
    credibility.” 181 N.J. at 154-58
    .   But defendants have not made any showing that
    the Witness has made false criminal accusations against others
    that would entitle them to scour through nine banker’s boxes of
    unrelated investigations in which the Witness has cooperated.
    22
    An open-ended search of unrelated investigative files in the
    hope that something may turn up that has impeachment value is
    not sanctioned by our discovery rule or jurisprudence.
    C.
    The informant’s privilege, N.J.R.E. 516, permits a witness
    to refuse to disclose the identity of a confidential informant
    “unless the judge finds that (a) the identity of the person
    furnishing the information has already been otherwise disclosed
    or (b) disclosure of his identity is essential to assure a fair
    determination of the issues.”   The State has legitimate concerns
    for the safety of witnesses who are considered “snitches” or
    “rats.”   The disclosure of the Witness’s identity in this case
    is necessary because he will testify against defendants.     The
    potential threat to his life, however, would increase
    exponentially if his identity were revealed to the targets in
    the unrelated drug investigations.   At least at this stage, we
    cannot find that the disclosure of the Witness’s identity in the
    unrelated investigations is necessary for defendants to receive
    a fair trial in this case.   See State v. Milligan, 
    71 N.J. 373
    ,
    384 (1976) (noting that disclosure depends on balancing of
    factors, “taking into consideration the crime charged, the
    possible defenses, the possible significance of the informer’s
    testimony, and other relevant factors” (quoting Roviaro v.
    23
    United States, 
    353 U.S. 53
    , 62, 
    77 S. Ct. 623
    , 628, 
    1 L. Ed. 2d 639
    , 646 (1957))).
    We recognize that the trial court ordered the redaction of
    names and locations from documents in the unrelated
    investigations.    Of course, such redactions devalue the utility
    of the materials requested by defendants.    For example,
    establishing a potential false accusation would be exceedingly
    difficult if the attorney does not know the name of the target.
    Nevertheless, despite the redactions and the protective order,
    the potential that the Witness’s identity will be disclosed in
    unrelated investigations is still a risk.     If defendants cannot
    signify with some specificity the relevance of the requested
    documents -- as opposed to speculative relevance -- the
    balancing of probative value against the dangers of disclosure
    weighs in favor of not removing the Witness’s cover, at least
    until defendants can make some concrete showing of need.
    We fully understand that the reliability of State
    informants and cooperating witnesses must be subject to special
    scrutiny because the charge-reduction and sentence-reduction
    incentives given to such witnesses have the capacity to induce
    false testimony.     That is why the State is required to make
    complete disclosure of the cooperation and plea agreements.
    Through defendants’ cross-examination and summation, the jury
    will know that the Witness has a powerful reason to curry favor
    24
    with the State.   In addition, the State is required as part of
    its discovery obligation to disclose known material false
    statements made by the Witness in the unrelated investigations
    because such disclosures bear on whether the State is enforcing
    or altering its cooperation agreement.   We have no reason to
    believe that the State will not fulfill its professional
    responsibilities in making any required disclosures.
    It bears repeating that the trial court’s in camera review
    of the documents in the unrelated investigations led the court
    to conclude that they did not have relevance to the present
    case.   Relevance is the touchstone of discovery.   Defendants’
    discovery request does not fall within the ambit of Rule 3:13-
    3(b) and is not supported by our jurisprudence.
    VI.
    For the reasons expressed, we reverse the judgment of the
    Appellate Division, vacate the discovery order, and remand to
    the trial court for further proceedings consistent with this
    opinion.
