In a strongly worded opinion addressing New York's Freedom of Information Law, a Manhattan Supreme Court justice has ruled that the New York City Police Department must release information to a police protest group about whether the department used technology to monitor or interrupt their cellphones during protests.

The decision from Justice Arlene Bluth could have wider implications for the NYPD's use of devices such as Stingrays, which mimic cell towers and intercept communications, and it comes after the NYPD had given a so-called “Glomar response”—essentially a nonresponse—to the group's FOIL request for information about surveillance of their social media activity and cellphones.

Glomar responses to freedom of information requests are rare and are typically used by federal agencies seeking to minimize national security risks. The responses state only that a government department or agency “can neither confirm nor deny” the existence of an investigation or records.

In the lawsuit before Bluth, a local group called Millions March NYC, which is affiliated with the Movement for Black Lives, argued that the NYPD's Glomar response failed to sufficiently address its 2017 FOIL request seeking documents tied to the NYPD's suspected monitoring of or interference with protesters' cellphones. According to the New York Civil Liberties Union, which teamed with Millions March to both lodge the FOIL request and bring the subsequent lawsuit, some protest organizers saw their phones shut down during marches or received messages indicating possible messaging-interference.

On Monday, Bluth ruled that the NYPD will have to provide documents or a non-Glomar FOIL exemption in response to certain FOIL requests submitted by the group. The police department had used Glomar to avoid giving substantive information in response to the majority of the requests filed in the group's multipronged submission.

“[The NYPD] may decline to provide records, but it must confirm or deny whether such records exist,” Bluth wrote as part of her ruling.

The justice also made clear—in detailed and often forcefully worded reasoning—that the case before her, involving the Millions March group's political protests and marches, was not the right situation for a Glomar response to be invoked.

“Terrorism-related concerns cannot be used to justify the use of a Glomar response in every FOIL context,” Bluth wrote, adding that “the petitioners [Millions March] here are protestors, engaging in First-Amendment protected activity. The only connection between protestors and terrorists appears to be that both groups use cell phones.”

In closing the opinion, she also said, “To embrace the use of Glomar response here would shut off all public inquiry and require respondent [NYPD] to hold itself accountable. That notion runs counter to the very purpose of freedom of information statutes. It certainly would not give terrorists the 'combination to the safe' to admit or deny that responsive records exist and, if such records exist, to offer a legitimate reason for citing an exemption. … FOIL is not about blind trust—it is about holding government officials accountable. That principle is fundamental to a democratic society and cannot be cast aside so easily.”

The NYPD issued a statement saying that it would review Bluth's decision and discuss its options with the city Law Department.

In addition, the department stated that “the NYPD uses the Glomar response exceedingly sparingly and only after careful consideration of the interests involved, including transparency, the need to protect the integrity of criminal investigations and public safety.”

In its own statement, the NYCLU hailed Bluth's ruling, and it criticized what it said was the NYPD's attempt to greatly “expand” the scope and use of Glomar in replying to a legitimate FOIL request.

“The court confirmed that the NYPD cannot vastly expand the scope of the Glomar response to deny the public access to basic information regarding the tactics and technologies used by police to monitor First Amendment-protected political activity,” Bobby Hodgson, an NYCLU staff attorney who argued the case, said.

“The court agreed that allowing the police to cite very general national security concerns in this case—to avoid transparency and accountability over the surveillance of protesters—would undermine the very purpose of the Freedom of Information Law,” he added.

In her opinion, Bluth also knocked back the NYPD's attempt to use an affidavit from John Miller, an NYPD deputy commissioner for intelligence and counterterrorism, who had warned in it, according to Bluth—quoting the affidavit—that revealing whether the NYPD had records responsive to the FOIL request would “potentially provide persons intent on committing a crime or an act of terrorism with critical intelligence to both successfully carry out such crime or attack and successfully evade detection because they would have the specific knowledge of the tools the NYPD may access in preventing attacks.”

Countered Bluth, “Although this affidavit provides ample reasons why a FOIL request for counter-terrorism information might merit a Glomar response, it does not provide any explanation for how it applies to this case. … Miller does not claim that these protestors were affiliated with the terrorists he lists in his affidavit, that these protestors engaged in behavior that might be connected to terrorism or that there might be terrorists hidden among the protestors. In fact, Miller does not allege that these protestors engaged in any terrorism-related behavior whatsoever.”

In addition, wrote the judge, “Miller appears to insinuate that deliberately using technology to interfere with protestors' cellphones would violate the law. If that were the case then, of course, respondent [NYPD] should be able to deny that any records exist because respondent, according to respondent, cannot interfere with a lawful protest. Revealing that the NYPD follows the law would not provide aid or comfort to terrorists. Of course, if respondent is using technology on protestors and, by its own account, violating the law, then it cannot hide exposure of that fact through a Glomar response.”

Bluth's decision in the 2017-filed lawsuit Millions March NYC v. NYPD pertained specifically to two prongs of the the group's FOIL request. In regard to a prong-request asking, in part, for records identifying and describing any software or technology that the NYPD uses to monitor protestors' social media, the justice ordered the police department to release unredacted documents relating to any such software or technology.
