OPINION OF THE COURT
In
People v Darden
(
This case arises out of the December 1, 1993 shootings of Milton Clarke (an auxiliary police officer) and Chester Martin. Clarke died as a result of the shooting; Martin survived but lost a leg. On March 18, 1994, a confidential informant — a witness in an unrelated homicide — saw a reward poster in a New York City Police Department station house concerning the shootings. The informant told Detective Neenan that a person he knew as “Tony” had confessed to him that he had committed the crimes. The informant gave a description of “Tony” and told Detective Neenan other details about the shootings. In addition, the informant stated that “Tony” had admitted shooting John Thomas in an unrelated incident on July 4, 1993.
Under Bronx County Indictment Number 3299/94, defendant was charged with second-degree murder, attempted murder, assault and several weapons offenses for the shootings of Clarke and Martin. A hearing was held on defendant’s motion to suppress the lineup identifications, at which Detective Neenan testified about the investigation and arrest of defendant, as well as the lineup. On cross-examination, defense counsel asked the detective for the name of the March 18, 1994 informant. The prosecutor objected. Defense counsel then asked, in the alternative, that the court examine the informant in camera to determine “whether this individual exists and what information he had.” The court denied defense counsel’s requests, stating that it did not need to examine the informant, or know his name, in order to make its probable cause determination.
Following the hearing, the court issued a written decision denying defendant’s motion to suppress, holding that the arrest was supported by probable cause. The court noted that the police had the right to rely on the information supplied by the confidential informant, because the informant provided a sufficient basis for his knowledge, had given reliable information in the past and furnished details consistent with information already known to the police. The court found additionally that the lineup was not suggestive. A jury convicted defendant of second-degree murder and attempted murder. 1
The Appellate Division affirmed, holding that the trial
The Informer’s Privilege at Suppression Hearings
The use of confidential informants to establish probable cause presents a difficult issue for the courts. As a general rule, hearsay is admissible at a suppression hearing
(see,
CPL 710.60 [4]). A police witness at a suppression hearing may establish probable cause by personal knowledge, as well as by information supplied by fellow officers or private citizens
(see, People v Washington,
As a counterbalancing principle, the defendant has a right to cross-examine the People’s witnesses at the suppression hearing
(see, People v Williamson,
Responding to these concerns, in 1974 this Court established a procedure to verify the testifying officer’s credibility while keeping the informant’s identity secret. The Court held that, where “there is insufficient evidence to establish probable cause apart from the testimony of the arresting officer as to communications received from an informer,” it would be “fair and wise” for the People to “be required to make the informer available for interrogation before the Judge”
(People v Darden, supra,
The Trial Court’s Obligation under Darden
In the present case, the trial court prohibited defendant from cross-examining Detective Neenan about the confidential
At the outset, we reject the People’s contention that probable cause could be established without the informant’s statements, which would render a Darden hearing unnecessary. The People argue before us that John Thomas’ identification of defendant as the person who shot him provided an independent basis for his arrest. The People, however, did not raise that theory before the trial court; they argued only that Thomas’ identification of defendant from a single photograph was “confirmatory” of the information provided by the confidential informant and other unnamed sources. The People’s current argument is therefore unpreserved. In any event, Thomas did not identify defendant until after he was arrested; indeed, the identification was made from defendant’s arrest photograph.
We likewise reject the People’s argument that the trial court’s refusal to follow the
Darden
procedure was a proper exercise of discretion. Where, as here, the informant’s testimony is necessary to establish probable cause, the court must grant the defendant’s request for a
Darden
hearing. To be sure, there are exceptions to the
Darden
rule. Informants need not be produced, for example, if they cannot be located despite the People’s diligent efforts
(see, People v Fulton,
The existence of these exceptions reinforces our holding that
Darden
did in fact establish a rule. If, as the People contend,
Darden
had established only a discretionary procedure, there would have been no need for exceptions. Further, our precedents speak of
Darden
hearings as required rather than discretionary. In
People v Serrano
(93 NY2d,
supra,
at 77), for example, this Court stated that a
Darden
hearing “is
required
‘where there is insufficient evidence to establish probable cause apart from the testimony of the arresting officer as to com
Similarly, in
People v Adrion
(
Further, as we stated in Serrano and Adrion, a Darden rule is necessary in order to fulfill the underlying purpose of Darden: insuring that the confidential informant both exists and gave the police information sufficient to establish probable cause, while protecting the informant’s identity. The surest way to accomplish this task is to produce the informant for an in camera examination. In addition, this rule gives clear guidance to lower courts and guarantees that “the protections of the Fourth Amendment have not been circumvented” (2 LaFave, Search and Seizure, supra, § 3.3 [g], at 203). 4
People v Huggins
(
Nor is a
Darden
hearing unnecessary if the police officer’s testimony satisfies the
Aguilar-Spinelli
test. That test provides that a tip from a hearsay informant (which may include an anonymous informant) may not be used unless the source of his knowledge is revealed and the informant is of known reliability
(see, People v DiFalco,
Finally, contrary to the Appellate Division, defendant was not required to make any threshold showing in order to be entitled to a
Darden
hearing
(see, Matter of Pierre H.,
Defendant, therefore, is entitled to remittal to Supreme Court for a Darden hearing, at which the court shall conduct an in camera examination of the confidential informant. Alternatively, if the People demonstrate that one of the exceptions to the Darden rule applies, they may establish the informant’s existence and reliability through other evidence.
Defendant’s remaining contention is without merit.
Accordingly, the order of the Appellate Division, insofar as appealed from, should be modified by remitting to Supreme Court for further proceedings in accordance with this Opinion and, as so modified, affirmed. If, on remittal, Supreme Court determines that probable cause to arrest was lacking, then the judgment of conviction under Indictment Number 3299/94 should be vacated and the motion to suppress granted. If Supreme Court determines that probable cause to arrest existed, then the judgment should be amended to reflect that result.
Judges Smith, Levine, Ciparick, Wesley and Rosenblatt concur.
Order, insofar as appealed from, modified, etc.
Notes
. Defendant subsequently pleaded guilty under a separate indictment (Bronx County Indictment Number 3396/94) to attempted murder and a weapons charge for the shooting of Thomas. The two indictments were consolidated for sentencing and appeal. Defendant, however, does not raise any issues relating to Indictment Number 3396/94 in this appeal, nor does he seek to set aside that conviction.
. Contrary to the People’s contention, the issue of probable cause to arrest is preserved for our review because, in its written decision denying defendant’s motion to suppress, the trial court “expressly decided” the question in response to a “protest by a party” (CPL 470.05 [2]).
. Serrano, in fact, fell within one of the exceptions to the Darden rule: no hearing was necessary because the informant had previously appeared before the Magistrate during the search warrant application.
. Elsewhere, some courts have endorsed a mandatory
Darden
procedure (see,
e.g., United States v Freund,
525 F2d 873, 877-878 [5th Cir] [remanding for in camera examination of informant where informant supplied information necessary to establishing probable cause],
