OPINION AND ORDER

JED S. RAKOFF, U.S.D.J.

In a lawsuit arising under the Administrative Procedure Act (APA), judicial review is generally limited to review of the administrative record. See 5 U.S.C. § 706; Citizens to Pres. Overton Park, Inc. v. Volpe, 401 U.S. 402, 420, 91 S.Ct. 814, 28 L.Ed.2d 136 (1971). But a defendant agency cannot have sole, unreviewable authority to decide which documents properly comprise the administrative record and which do not. Indeed, excluding courts from this determination would "impede [them] from conducting the `thorough, probing, in-depth review' of the agency action with which [they are] tasked." In re Nielsen, No. 17-3345 (2d Cir. Dec. 27, 2017), Slip Op. at 2 (quoting Overton Park, 401 U.S. at 415, 91 S.Ct. 814. For this reason, the Court grants plaintiffs' motion to compel defendants to produce a log of deliberative documents withheld from the administrative record on the basis of asserted privilege.

In the underlying civil action, plaintiffs the State of New York and the Kings County District Attorney bring suit under the APA to challenge the decision by U.S. Immigration and Customs Enforcement (ICE) to implement a Directive that allows ICE agents to conduct civil immigration arrests in and around state courthouses.1 Compl. ¶¶ 1-12 (Sept. 25, 2019), Dkt. 1. The Court, after denying defendants' motion to dismiss, directed defendants to produce the administrative record by no later than January 3, 2020. Opinion and Order at 35 (Dec. 19, 2019), Dkt. 51. On January 3, defendants filed a 170-page record. Dkt. 55. On January 23, plaintiffs filed the instant motion to compel defendants to produce a privilege log identifying materials withheld from the administrative record. Notably, while this motion was pending, plaintiffs informed the Court that they had identified potential gaps in the administrative record that are not attributable to claims of privilege. Defendants conceded that some documents may have inadvertently been omitted from the record, and at a court conference on January 31, the Court ordered defendants to supplement the record by no later than February 14.

The Court now also grants plaintiffs' motion to compel defendants to produce a privilege log. Defendants primarily rely on out-of-circuit cases supporting the proposition that — because privileged, deliberative materials are not part of the administrative record — an agency ordinarily need not produce a log of documents withheld from the record on the basis of privilege. E.g., Oceana, Inc. v. Ross, 920 F.3d 855, 865 (D.C. Cir. 2019) ("[P]redecisional and deliberative documents are not part of the administrative record to begin with, so they do not need to be logged as withheld from the administrative record.") (internal quotation and citations marks omitted); Great Am. Ins. Co. v. United States, No. 12-cv-9718 (SF), 2013 WL 4506929 (N.D. Ill. Aug. 23, 2013); see also Tafas v. Dudas, 530 F.Supp.2d 786, 802 (E.D. Va. 2008) ("Before [plaintiff] can demand that the [agency] produce a privilege log substantiating any claims of privilege, he must first show that documents that belong in the administrative record are missing.").

But these cases are not binding on the Court,2 and the Court does not find their argument persuasive. It is uncontested that intra-agency materials that genuinely fall under the deliberative process privilege are not part of the administrative record. Comprehensive Cmty. Dev. Corp. v. Sebelius, 890 F.Supp.2d 305, 312 (S.D.N.Y. 2012). It does not follow from this premise, however, that courts should not have a role in reviewing whether this privilege was properly invoked and applied to particular documents so withheld. Courts routinely make determinations of privilege in other contexts, and they are expert at doing so. As to the deliberative process privilege specifically, federal courts are often asked in FOIA litigation, for example, to determine whether this privilege applies. See 5 U.S.C. § 552(b)(5); Am. Civil Liberties Union v. Nat'l Sec. Agency, 925 F.3d 576, 592 (2d Cir. 2019). There is no reason why courts cannot make identical determinations in APA lawsuits in order to determine the proper scope of the administrative record.

Moreover, defendants' concern that compelling them to produce a privilege log would undermine the limited nature of judicial review in APA actions is misplaced. Allowing courts a role in adjudicating whether particular documents are properly withheld from the record on the basis of privilege is consistent with, not contrary to, the mandate of the courts to review the "whole record," Overton Park, 401 U.S. at 419, 91 S.Ct. 814, and evaluate whether the agency "examine[d] the relevant data and articulate[d] a satisfactory explanation for its action." Motor Vehicle Mfrs. Ass'n v. State Farm Mut. Auto. Ins. Co., 463 U.S. 29, 43, 103 S.Ct. 2856, 75 L.Ed.2d 443 (1983). Without a privilege log, "the District Court would be unable to evaluate the Government's assertions of privilege," Nielsen, Slip Op. at 3, and therefore unable to determine whether an assertedly-privileged document was properly excluded from the record. And a court that allowed an agency to withhold documents wrongly marked as deliberative would not be performing judicial review in the exacting manner prescribed by the Supreme Court in Overton Park and State Farm. "Indeed, judicial review cannot function if the agency is permitted to decide unilaterally what documents it submits to the reviewing court as the administrative record." In re United States, ___ U.S. ___, 138 S.Ct. 371, 372, 199 L.Ed.2d 417 (Mem.) (2017) (Breyer, J., dissenting). On the other hand, were a court satisfied that all of the documents listed on a privilege log were in fact deliberative, it would not need to inquire into those documents any further.3 Nothing about a privilege log, therefore, violates the general requirement that judicial review and discovery in an APA action be limited to the administrative record. See Nat'l Audubon Soc. v. Hoffman, 132 F.3d 7, 14 (2d Cir. 1997) (citing Fla. Power & Light Co. v. Lorion, 470 U.S. 729, 743-44, 105 S.Ct. 1598, 84 L.Ed.2d 643 (1985)); Sharkey v. Quarantillo, 541 F.3d 75, 92 n.15 (2d Cir. 2008).

The primary Second Circuit authority on this question is clearly supportive of plaintiffs' position. In Nielsen, the Second Circuit, in an unpublished summary order, denied a petition for a writ of mandamus to stay the district court's order compelling the defendant agency to produce a privilege log to plaintiffs. Slip Op. at 1. Although the decision rested in part on the extraordinarily high standard for a writ of mandamus, Slip Op. at 1-2; see Balintulo v. Daimler AG, 727 F.3d 174, 186 (2d Cir. 2013), its reasoning suggests that the court would also have upheld the district court's order on the merits. In particular, the Second Circuit noted that the district court's order compelling the agency to produce a privilege log I was appropriate because, without a privilege log, the agency's assertions of privilege would be effectively unreviewable. Slip Op. at 3.

Indeed, that logic suggests that district courts should grant motions to compel production of a privilege log in APA actions as a matter of course, and at least one other court in this district has effectively so held. State of N.Y. v. Dep't of Commerce, 18-cv-2921 (JMF), Argument Tr. 78:10-14 (S.D.N.Y. July 3, 2018), Dkt. 205 ("The first issue whether defendants need to produce a privilege log is easily resolved. Put simply, defendants' arguments are, in my view, squarely foreclosed by the Second Circuit's December 17, 2017 rejection of similar arguments [in] In re Nielsen.")

But even if such a broad requirement did not apply as a matter of course, two case-specific factors that the court in Nielsen viewed as weighing in favor of compelling defendants to produce a privilege log are also present here. First, in Nielsen, the plaintiffs had identified to the district court specific materials that appeared to be missing from the administrative record. Slip Op. at 2-3. Here, similarly, the defendants acknowledge they may have inadvertently omitted certain documents from the record. While there is no suggestion that they did so in bad faith, the earlier omission further justifies some involvement by plaintiffs and the Court in determining what must be included in the administrative record. Second, the court in Nielsen also noted that the number of documents in question was sufficiently small that it would not pose an undue burden for the Government to produce a privilege log. Slip Op. at 3-4. Here, the administrative record is very brief, only 170 pages in length, which leads the Court to believe that there are correspondingly few deliberative documents that would need to be listed on a privilege log, and that the burden would consequently be small.

A case cited by defendants, Comprehensive Community Development Corp. v. Sebelius, 890 F.Supp.2d 305 (S.D.N.Y. 2012), does not provide a compelling rationale for a contrary result. In that case, another court in this district denied plaintiffs' motion to compel the defendant agency to expand the administrative record (as opposed to providing a privilege log), reasoning that "an agency's designation of the administrative record is generally afforded a presumption of regularity," id. at 309 (internal quotation marks omitted), and that "a court may review extra-record evidence only where `there has been a strong showing in support of a claim of bad faith or improper behavior on the part of the agency decision-maker ...,'" id. (quoting Hoffman, 132 F.3d at 14). But to the extent that the "presumption of regularity" due to ICE is not already undermined by the conceded omissions from the record, a privilege log is not necessarily inconsistent with this presumption. Production of a privilege log does not give the Court any occasion to expand the administrative record to encompass any document not properly included; it simply allows the Court to have some oversight of the agency's assertions of privilege, the same role it would assume with respect to any other litigant.

For the foregoing reasons, the Court grants plaintiffs' motion and directs defendants to produce a privilege log identifying deliberative materials withheld from the administrative record by no later than February 28, 2020.

SO ORDERED.
