The United States Court of Federal Claims certified this interlocutory appeal to examine the limits of the “deliberative process privilege.” The trial court decided that only the Agency head could invoke the privilege on the Agency’s behalf. Therefore, the trial court rejected as procedurally flawed a process allowing a high ranking subordinate to invoke the privilege. Marriott Int’l Resorts, L.P. v. United States, 61 Fed.Cl. 411 (2004) (Court of Federal Claims Decision). In the absence of binding precedent on the specific issue before the court, the court adopts the position that the deliberative process privilege permits delegation. A majority of our sister circuits have reached the same conclusion. Therefore, this court reverses and remands for further proceedings.

I.

The case arises in the context of a tax case in the Court of Federal Claims. Marriott International Resorts, L.P. (Marriott) requested production of all documents that the Internal Revenue Service (IRS or Agency) relied upon in defining “liability” under 26 U.S.C. § 752. See id. at 414. Marriott alleges the Agency’s pre-1995 interpretation of § 752 justified its treatment of various short-sale transactions as liabilities in its 1994 tax returns. Id. at 413. In 1995, however, the Agency reinterpreted § 752 in a manner that excluded Marriott’s short-sale transactions, thereby increasing Marriott’s 1994 taxable income by $72,946,839. Id. Thereafter, Marriott filed suit in the Court of Federal Claims, challenging the Agency’s treatment of its short-sale transactions. Id. As summarized by the trial court:

In pursuit of support for those allegations, Marriott ... requested from the government all documents relied upon by the IRS “in formulating its position with respect to the definition of ‘liability’ in Treasury Regulations issued under [Internal Revenue] Code section 752 in 1988 and 1991 and various revenue rulings in which the IRS purported to define the term.”

Id. at 414 (citing Pis.’ Mot. at 9-10) (alteration in original).

While producing some documents in response to Marriott’s request, the Government withheld or redacted portions of 339 responsive documents under a claim of[*1304] “executive privilege.” Id. Notably, the Commissioner of the IRS did not personally invoke the privilege claim. Id. Rather, the Commissioner delegated the authority to an Assistant Chief Counsel who. invoked the privilege during an exhaustive examination of the voluminous documents at issue. Id. (citing Delegation Order No. 220 (Rev.3), 1997 WL 33479282).

Without addressing the merits of the privilege claim, the trial court rejected the Agency’s invocation of the privilege as procedurally flawed because, in its view, the privilege could only be invoked “by the head of agencies after personal familiarization with the documents involved and a determination that disclosure would significantly and adversely affect the agency’s vital functions.” Id. at 417. In reaching that conclusion, the trial court relied on a case from this court’s predecessor, the United States Court of Claims, namely Cetron Electronic Corporation v. United States, 207 Ct.Cl. 985, 1975 WL 6632 (1975) (Cetron Elec.). The trial court also noted other cases in its court on this issue. See Vons Companies, Inc. v. United States, 51 Fed.Cl. 1, 23 (2001); Abramson v. United States, 39 Fed.Cl. 290, 295 (1997); Walsky Const. Co. v. United States, 20 Cl.Ct. 317, 320 (1990); Deuterium Corp. v. United States, 4 Cl.Ct. 361, 364 (1984). Based on its finding that the Government had not properly invoked the privilege, the trial court ordered either production of all the documents or invocation of the privilege properly by the Commissioner himself after personal review of the documents. Court of Federal Claims Decision, 61 Fed.Cl. at 419-20. With the trial court’s permission, the Government filed the present interlocutory appeal to challenge this holding.

II.

As noted, the trial court felt bound by the holding of the Court of Claims in Ce-tron Elec. See id. at 417. The trial court further commented that Cetron Elec. was consistent with an earlier Court of Claims decision, Kaiser Aluminum & Chemical Corporation v. United States, 141 Ct.Cl. 38, 157 F.Supp. 939 (1958) (Kaiser Aluminum). Id. The case law of the Court of Claims, including both Cetron Elec. (1975) and Kaiser Aluminum (1958), bind this court. South Corp. v. United States, 690 F.2d 1368, 1370 (Fed.Cir.1982) (en banc). Cetron Elec, and Kaiser Aluminum, however, did not address or decide the issue presently before this court.

Kaiser Aluminum occasionally receives credit as the first federal case to recognize a deliberative process privilege.^[1] See e.g., Michael N. Kennedy, Escaping The Fishbowl: A Proposal To Fortify The Deliberative Process, 99 NW. U.L.Rev. 1769, 1779 (2005). Kaiser Aluminum involved an alleged breach of contract in the United States’ sale of war plants to Kaiser Aluminum & Chemical Corporation (Kaiser) and Reynolds Metal Company (Reynolds). 157 F.Supp. at 941. During the litigation, Kaiser sought documents from the General Services Administration (GSA) relating to the Kaiser and Reynolds sales:

[T]he request included all internal GSA reports, memoranda, or other documents concerning these sales to Kaiser and Reynolds prepared by all employees or agents of the Administration for in-tra-agency use, particularly prior drafts of the Kaiser contract with Agency interpretation and justification thereof and similar papers in connection with that[*1305] claim. There was also sought the like intra-agency reports and comparisons concerning the Reynolds contract.

Id. at 942. In response, the Government produced all but one document “on the ground that it was ‘contrary to the national interest.’ ” Id. The Kaiser Aluminum opinion decided the propriety of this privilege claim.

Initially, “[Kaiser] objected that ... the [Government’s] claim of privilege had not been made by the head of the department after actual personal consideration, citing United States v. Reynolds, 345 U.S. 1, 7, 73 S.Ct. 528, 97 L.Ed. 727 (1953).” Id. However, “[t]he Government thereupon filed a letter dated June 11, 1957, of the agency head, the Administrator of the General Services Administration ... declining to produce the document.” Id. at 943 (emphasis added). Thus, the Court of Claims in Kaiser Aluminum did not face the question of delegation of the deliberative process privilege as in the present case.^[2]

Cetron Elec, involved “the failure of ... a defunct wholly owned subsidiary ... to withhold and pay over ... federal .employment taxes for the second and third calendar quarters of 1963.” Cetron Elec., 207 Ct.Cl. 985,. During the litigation, Cetron Electronic Corporation (Cetron) sought:

internal reports of officials of [the] IRS relating to assessment of the 100-per-cent penalty tax under section 6672 of the Internal Revenue Code of 1954, against those persons deemed responsible for the failure of Associated Engineers to collect and pay over to [the] IRS the taxes at issue.

Id. In response, the Government refused to produce seven relevant documents. It invoked “an alleged general privilege the Government has against disclosure of any intra-agency communications that contain opinions, conclusions, and reasoning of Government officials used in the administrative decision making process.” Id. 207 Ct.Cl. 985, 1975 WL 6632 at *3. As with Kaiser Aluminum, the Cetron Elec. opinion focuses on the propriety of the privilege claim. Id. 207 Ct.Cl. 985, 1975 WL 6632 at *5.

Notably, however, the Government did not invoke the deliberative process privilege in Cetron Elec.3 Rather, as stated in the opinion:

Of Course, even executive privilege has its limitations and is not absolute, but we do not need to go into that here since it is not claimed in this case.

Id. 207 Ct.Cl. 985, 1975 WL 6632 at *5 (emphasis added); see also id. 207 Ct.Cl. 985, 1975 WL 6632 at *3 (“Defendant[*1306] seeks to distinguish and does not assert the doctrine of executive privilege .... ”). Thus, Cetron Elec, did not decide anything relative to the dimensions of the executive privilege at issue in the present case. Hence, Cetron Elec, could not decide specific conditions for invocation of a privilege not invoked in that case. See Yankee Atomic Elec. Co. v. United States, 54 Fed.Cl. 306, 310 n. 4 (2002) (commenting that Cetron Elea's discussion of the executive privilege is merely dictum).

Moreover, even if the general discussion in Cetron Elec, appears to apply to the deliberative process privilege generally, the Court of Claims did not confront or consider the propriety of a delegated invocation of the privilege. Nowhere does Ce-tron Elec, even discuss the Agency’s procedure of invocation of the privilege claim that was specifically not asserted in the case before this court’s predecessor. Thus, Cetron Elec, did not address or decide the issue before this court.

For these reasons, the trial court’s reliance on Kaiser Aluminum and Cetron Elec, was misplaced. Neither Kaiser Aluminum nor Cetron Elec, rejected a delegated invocation of the deliberative process privilege. Thus, this court confronts for the first time the specific issue presented in this case.

III.

The “Agency head” requirement originated in the Supreme Court’s Reynolds opinion, which involved tort claims stemming from a late 1940s Air Force plane crash. 345 U.S. at 2-3, 73 S.Ct. 528. In Reynolds, the court upheld the Secretary of the Air Force’s refusal to turn over various military documents as privileged under the “military and state secrets privilege.” Id. at 7, 73 S.Ct. 528. Reynolds noted that the privilege was not to be lightly invoked and thus required a “formal claim of privilege, lodged by the head of the department which has control over the matter, after actual personal consideration by that officer.” Id. at 7-8, 73 S.Ct. 528 (emphasis added). This passage in Reynolds gave rise to the “Agency head” invocation rule.

Unlike Reynolds, however, the present case involves the deliberative process privilege, not the military and state secrets privilege. On this point, our sister circuits have split over whether the Agency head invocation rule outlined in Reynolds applies to the deliberative process privilege as well as the military and state secrets privilege. See Dep’t of Energy v. Brett, 659 F.2d 154 (Temp.Emer.Ct.App.1981) (holding the trial court erred in ruling the deliberative process privilege could only be invoked by an Agency head)^[4] ; Landry v. Fed. Deposit Ins. Corp., 204 F.3d 1125, 1135 (D.C.Cir.2000) (commenting that lesser officials can invoke the deliberative process and law enforcement privileges); Branch v. Phillips Petroleum Co., 638 F.2d 873, 882-83 (5th Cir.1981) (commenting that, while Reynolds indicates Agency head invocation is required, the Equal Employment Opportunities Commission (EEOC) sufficiently complied when the director of its Houston office, a subordinate, invoked the privilege on the EEOC’s behalf). Contra United States v. O’Neill, 619 F.2d 222, 225 (3d Cir.1980) (rejecting invocation of executive privilege by an attorney[*1307] rather than the department head). For the following reasons, this court determines the majority rule, as explained by the United States Court of Appeals for the District of Columbia Circuit in Landry, applies in this circuit.

In Landry, the Federal Deposit Insurance Corporation (FDIC) invoked the deliberative process privilege to justify withholding various documents sought in pretrial discovery. Landry, 204 F.3d at 1134. Notably, the head of the FDIC did not invoke the privilege; rather, the Memphis Regional Director of the FDIC invoked the privilege on the FDIC’s behalf. Id. In the DC Circuit’s eyes, delegated invocation in that case was entirely permissible because “[ijnsistence on an affidavit from the very pinnacle of agency authority would surely start to erode the substance of ‘actual personal’ involvement.” Id. This court agrees.

Delegated review by a subordinate undoubtedly results in a more thorough, more consistent, and timelier review of potentially privileged documents than personal review by the Agency head. In the present case, for example, the 339 documents at issue came from a larger cache of more than 4,000 relevant pages of material. The subordinate, even though familiar with the documents and the nature of the privilege, still consumed over thirty-one hours in review of these records. Even if the Commissioner — -undoubtedly less familiar with the nature of the documents at issue and less practiced at large-scale document review — could review documents as efficiently as the subordinate, the burden of personal review of each and every document in each and every case the IRS is involved in could interfere with the Commissioner’s overall responsibilities. See Martin v. Albany Bus. Journal, Inc., 780 F.Supp. 927 (N.D.N.Y.1983) (commenting that requiring personal review by an Agency head would bring the government to a virtual standstill). Faced with that difficult assignment, the Commissioner would likely either conduct a superficial document review to complete the process in a timely manner or conduct a detailed review over a long and drawn out period (avoiding conflicts with other responsibilities), thereby significantly extending litiga-tions. Thus, Landry correctly noted that delegation promotes both efficiency in judicial administration and actual personal involvement in the complex process of invoking the privilege. See Landry, 204 F.3d at 1134.

Moreover, significant differences between the deliberative process privilege and other privileges (e.g., the military and state secrets privilege) justify delegated invocation in this case. Of most importance, the state secrets privilege is an absolute privilege; the deliberative process privilege is not. Thus, in a case with the state secrets branch of the executive privilege, even the most compelling need for the withheld documents cannot overcome the claim of privilege. See Reynolds, 345 U.S. at 11, 73 S.Ct. 528; Halkin v. Helms, 690 F.2d 977, 990 (D.C.Cir.1982). Moreover, in such a case, a court generally may not conduct in-camera review of the highly sensitive withheld documents. See Reynolds, 345 U.S. at 10, 73 S.Ct. 528. Thus, a trial court enjoys little oversight of the Government’s invocation of a privilege involving military and state secrets.

In contrast, a showing of compelling need can overcome the qualified deliberative process privilege. See e.g., In re Sealed Case, 121 F.3d 729, 737 (D.C.Cir.1997). Moreover, a trial court may conduct in-camera review of documents under this qualified branch of the executive privilege doctrine. The qualified deliberative process privilege is subject to judicial oversight. These differences, among others,[*1308] support a reasonable delegation procedure for invocation of the deliberative process privilege.

Hence, for these reasons, this court concludes that the head of an Agency can, when carefully undertaken, delegate authority to invoke the deliberative process privilege on the Agency’s behalf. This case provides an excellent example of the Agency’s care in the delegation process. Given the large number of documents implicated by Marriott’s request, the Commissioner issued Delegation Order No. 220 (Rev.3), expressly excluding from its scope the authority to claim the state secrets privilege and establishing detailed criteria for claiming the deliberative process privilege:

Executive privilege may be claimed only for those internal or inter-agency records or information that are predecisional and deliberative, the disclosure of which would significantly impede or nullify Internal Revenue Service actions in carrying out a responsibility or function or would constitute an unwarranted invasion of personal privacy.

Delegation Order No. 220 (Rev.3), 1997 WL 33479282. In addition, the subordinate selected by the Commissioner, an Assistant Chief Counsel, holds a senior position within the Agency and is responsible for planning, administering and evaluating the Agency’s disclosure policies and procedures. Notably, this subordinate is not directly responsible for or involved in substantive tax litigation, including this case. Thus, the Commissioner, in his delegation, provided detailed criteria for invoking the privilege. Moreover he chose a high ranking Agency official with expertise in the nature of the privilege claim and documents at issue. This delegation by the Commissioner was entirely proper and consistent with the majority rule outlined in Landry. Because the trial court erroneously rejected the deliberative process privilege, this court reverses.

IV.

In sum, this court commends the trial court’s caution in carefully consulting this court’s precedents, namely, Cetron Elec. and Kaiser Aluminum. In this case, however, the trial court’s reliance on those inapposite cases was misplaced. These cases did not rule on the propriety of a delegated invocation of the deliberative process privilege. For the reasons stated, this court concludes an Agency head may delegate the authority to invoke the deliberative process privilege on the Agency’s behalf. The decision of the trial court is reversed and the case remanded for further proceedings consistent with this opinion.
