Functions that federal law and policy require to be performed by government personnel, not contractor employees, are known as "inherently governmental functions." Such functions have been a topic of interest in recent Congresses, in part, because of questions about sourcing policy (i.e., whether specific functions should be performed by government personnel or contractor employees). There have also been questions about the various definitions of inherently governmental function given in federal law and policy and, particularly, whether the existence of multiple definitions of this term may have resulted in contractor employees performing functions that should be performed by government personnel. Previously, the 110 th Congress had tasked the Office of Management and Budget (OMB) with reviewing existing definitions of inherently governmental function to determine whether such definitions are "sufficiently focused" to ensure that only government personnel perform inherently governmental functions or "other critical functions necessary for the mission of a Federal department or agency"; developing a "single consistent definition" of inherently governmental function that would address any deficiencies in the existing definitions, reasonably apply to all agencies, and ensure that agency personnel can identify positions that perform inherently governmental functions; developing criteria for identifying "critical functions" that should be performed by government personnel; and developing criteria for identifying positions that government personnel should perform in order to ensure that agencies develop and maintain "sufficient organic expertise and technical capacity" to perform their missions and oversee contractors' work. Partly in response to this charge, OMB, through the Office of Federal Procurement Policy (OFPP), issued Policy Letter 11-01 on September 12, 2011. As explained below, Policy Letter 11-01 adopts the definition of inherently governmental function given in the Federal Activities Inventory Reform (FAIR) Act of 1998, rather than creating a new definition. However, Policy Letter 11-01 does establish two tests for identifying inherently governmental functions, as well as defines a critical function as one "that is necessary to the agency being able to effectively perform and maintain control of its mission and operations." This report surveys the definitions of inherently governmental function given in Policy Letter 11-01, the FAIR Act, and other sources. It also notes specific functions that have been designated as inherently governmental or commercial by statute, regulation, policy, or GAO or judicial decision. Its primary focus is upon government-wide statutes, regulations, and policy documents, not agency-specific ones. The report begins with (1) statutory definitions and declarations before turning to those in (2) policy guidance, (3) administrative law, and (4) judicial decisions. However, the report's discussion of one type of definition often cross-references other types of definitions because of the complex interrelationships Congress and the Executive have established between the various provisions of law and policy on this topic. The Federal Activities Inventory Reform (FAIR) Act of 1998 provides the primary statutory definition of inherently governmental function . There are, however, several other statutory definitions of inherently governmental function and "functions closely associated with inherently governmental functions." Some of these definitions mirror the definitions of the FAIR Act or Office of Management and Budget (OMB) Circular A-76, discussed below, while others incorporate the definitions of the FAIR Act or OMB Circular A-76 by reference. There are also numerous statutory provisions declaring that specific functions are inherently governmental. Originally introduced as the Freedom from Government Competition Act of 1997, the FAIR Act was designed to promote executive agencies' compliance with OMB Circular A-76. OMB Circular A-76 predates the FAIR Act and expresses the federal government's general policy of relying on competitive private enterprises to supply the commercial supplies and services it needs. OMB Circular A-76 also provides procedures for agencies to conduct cost comparisons to determine whether the government or private enterprises should perform specific activities on the government's behalf. However, although OMB Circular A-76 established these policies and procedures prior to 1998, it reportedly failed to result in public-private competitions for the performance of commercial activities, or in agencies' contracting with the private sector for performance of their commercial activities. The FAIR Act sought to address this situation by requiring agencies to compile annual lists of all commercial activities they perform and make these lists available to Congress and the public. The FAIR Act does not require agencies to contract out any particular activities, however. It requires only that agencies use competitive processes to select the source when they consider contracting with private sector sources for performance of certain activities performed by government employees. Although the FAIR Act's primary focus is upon commercial activities performed by government agencies, it defined inherently governmental function in order to contrast such functions with commercial activities. The FAIR Act's definition of inherently governmental function is brief: "The term 'inherently governmental function' means a function that is so intimately related to the public interest as to require performance by Federal Government employees." This definition is, however, followed by extensive elaboration on the types of functions included in and excluded from the definition of inherently governmental functions under the act. The FAIR Act describes the "functions included" within its definition of inherently governmental function as functions that "require either the exercise of discretion in applying Federal Government authority or the making of value judgments in making decisions for the Federal Government, including judgments relating to monetary transactions and entitlements." The act then gives a non-exclusive list of the types of "functions included," namely: 1. binding the United States to take, or not to take, action by contract, policy, regulation, authorization, order, or otherwise; 2. determining, protecting, and advancing U.S. economic, political, territorial, property, or other interests by military or diplomatic action, civil or criminal judicial proceedings, contract management, or otherwise; 3. significantly affecting the life, liberty, or property interests of private persons; 4. commissioning, appointing, directing, or controlling officers or employees of the United States; or 5. exerting ultimate control over the acquisition, use, or disposition of the real or personal, tangible or intangible, property of the United States, including the collection, control, or disbursement of appropriated and other federal funds. The FAIR Act further describes the "functions excluded" from its definition of inherently governmental function as functions involving (1) gathering information for or providing advice, opinions, recommendations, or ideas to federal officials, or (2) any function that is primarily ministerial and internal in nature. It concludes by giving examples of ministerial and internal functions, which include building security, mail operations, cafeteria operations, housekeeping, facilities operations and maintenance, warehouse operations, motor vehicle fleet management operations, and other routine electrical or mechanical services. The FAIR Act's definition of inherently governmental function and listing requirements apply to all executive branch agencies named in 5 U.S.C. §101, all military departments named in 5 U.S.C. §102, and all independent establishments as defined in 5 U.S.C. §104. However, the FAIR Act explicitly exempts from the act's requirements (1) the Government Accountability Office (GAO); (2) government corporations or government-controlled corporations, as defined in 5 U.S.C. §103; (3) non-appropriated funds instrumentalities, as described in 5 U.S.C. §2105(c); (4) certain depot-level maintenance and repair activities of the Department of Defense, as described in 10 U.S.C. §2460; and (5) agencies with fewer than 100 full-time employees as of the first day of the fiscal year. In addition to the FAIR Act, other statutes have "definitions" sections that include inherently governmental function or functions closely associated with inherently governmental functions . Two of these statutes provide a definition of inherently governmental function that, while closely related to the definitions of the FAIR Act and OMB Circular A-76, discussed below, does not reproduce either of these definitions verbatim. Specifically, the Coast Guard appropriations authorization act for FY2004 and FY2005 and the National and Community Service Trust Act of 1993 both define an inherently governmental function as: any activity that is so intimately related to the public interest as to mandate performance by an officer or employee of the Federal Government, including an activity that requires either the exercise of discretion in applying the authority of the Government or the use of judgment in making a decision for the Government. The verb "mandate" in this definition matches the verb in the definition of OMB Circular A-76, but the definition otherwise departs from the definition of OMB Circular A-76 by using "officer or employee of the Federal Government" where OMB Circular A-76 uses "Federal Government employees." However, this definition does expressly incorporate the functions of exercising discretion and using judgment that are mentioned in OMB Circular A-76 and are among the "functions included" within the FAIR Act's definition of inherently governmental functions. Outside of the Coast Guard appropriations authorization act for FY2004 and FY2005 and the National and Community Service Trust Act of 1993, however, no statute provides a definition of inherently governmental function different from that in the FAIR Act or OMB Circular A-76. Many statutes incorporate the definition from OMB Circular A-76, in particular, by reference when defining inherently governmental function . Several of these statutes also use the related term, "functions closely associated with inherently governmental functions," but likewise incorporate the definition of OMB Circular A-76 by reference. Several provisions of federal law declare that specific functions are inherently governmental without defining inherently governmental function . Sometimes, specific functions are defined as inherently governmental without reference to the FAIR Act or the employees performing the functions at the time of the statute's enactment. Examples of such functions are (1) the preparation of agency strategic plans and program performance reports under the Government Performance and Results Act of 1993, and (2) functions connected with the operation and maintenance of hydroelectric power-generating facilities at water resources projects of the Army Corps of Engineers. At other times, specific groups of employees, who were performing certain functions at the time of the statute's enactment, are classified as inherently governmental for purposes of the FAIR Act. Examples include federal employees at the National Energy Technology Laboratory and instructor staff at the Federal Law Enforcement Training Center. At yet other times, Congress effectively renders certain functions inherently governmental, at least temporarily, without classifying them as such, by providing that appropriated funds cannot be expended to contract them out. Finally, Congress sometimes signals its concerns about the executive branch's classification of specific functions without either enacting legislation designating the functions as inherently governmental, or precluding the use of appropriated funds to contract the functions out. Congress can do this by expressing its sense that certain functions are inherently governmental, or by imposing additional restrictions—beyond those in the FAIR Act, OMB Circular A-76, the Federal Acquisition Regulation (FAR), or OFPP Policy Letter 11-01—upon contracting out activities that some commentators may assert are inherently governmental. Alternatively, but more rarely, Congress expresses its sense that certain functions are commercial. As discussed below, commercial functions are functions that could potentially be performed by contractor personnel. In other cases, Congress appropriates funds to contract out activities that some commentators might seek to classify as inherently governmental. OMB Circular A-76 provides the other main definition of inherently governmental functions used in federal law and policy. Office of Federal Procurement Policy (OFPP) Policy Letter 11-01, which was issued on September 12, 2011, also provides guidance on inherently governmental and related functions. Policy Letter 11-01 adopts the FAIR Act's definition of inherently governmental function , as well as the listings of inherently governmental functions and functions closely associated with the performance of inherently governmental functions given in the Federal Acquisition Regulation (FAR). Policy Letter 11-01 does, however, establish a definition of critical functions , as well as new tests for identifying inherently governmental functions and guidance on pre- and post-award management of contracts for critical functions and functions closely associated with the performance of inherently governmental functions. Like its predecessors, the current OMB Circular A-76 "establishes federal policy for the competition of commercial activities." It both (1) articulates the "longstanding policy of the federal government ... to rely on the private sector for needed commercial services," and (2) establishes procedures for agencies to use in determining whether their commercial activities should be performed under contracts with the private sector or in-house by agency personnel. Although pre-2003 versions of OMB Circular A-76 focused on listing only commercial activities, the current version of OMB Circular A-76 requires agencies to list all activities they perform and classify these activities as commercial or inherently governmental. All activities classified as inherently governmental under OMB Circular A-76 must be performed by government personnel. Only those activities classified as commercial may be considered for contracting out. Even in its pre-2003 versions, before agencies were required to list and classify inherently governmental activities, OMB Circular A-76 defined inherently governmental function when characterizing such functions as the opposite of commercial activities. Circular A-76's definition is itself brief, like the definition in the FAIR Act. The current version of OMB Circular A-76 says only that "[a]n inherently governmental activity is an activity that is so intimately related to the public interest as to mandate performance by government personnel." However, OMB Circular A-76, also like the FAIR Act, follows its brief definition of inherently governmental function with clarification and examples. Thus, the paragraph within the current version of OMB Circular A-76 that defines inherently governmental function continues by stating: [Inherently governmental] activities require the exercise of substantial discretion in applying government authority and/or in making decisions for the government. Inherently governmental activities normally fall into two categories: the exercise of sovereign government authority or the establishment of procedures and processes related to the oversight of monetary transactions or entitlements. An inherently governmental activity involves: (1) Binding the United States to take or not to take some action by contract, policy, regulation, authorization, order, or otherwise; (2) Determining, protecting, and advancing economic, political, territorial, property, or other interests by military or diplomatic action, civil or criminal judicial proceedings, contract management, or otherwise; (3) Significantly affecting the life, liberty, or property of private persons; or (4) Exerting ultimate control over the acquisition, use, or disposition of United States property (real or personal, tangible or intangible), including establishing policies or procedures for the collection, control, or disbursement of appropriated and other federal funds. This language largely corresponds to that in the FAIR Act's examples of "functions included" in its definition of inherently governmental function . However, the FAIR Act does include one example that is not included in OMB Circular A-76: the commissioning, appointing, directing, or controlling of officers or employees of the United States. The current version of OMB Circular A-76 then provides some further explanations that are unlike those in the FAIR Act or other sources. It first distinguishes between the exercise of discretion per se , which it says does not make a function inherently governmental, and the exercise of "substantial discretion," which it says makes a function inherently governmental. It then notes that "[a]n activity may be provided by contractor support ... where the contractor does not have the authority to decide on the course of action, but is tasked to develop options or implement a course of action, with agency oversight," before listing six factors that agencies should consider to avoid transferring inherently governmental functions to contractors (e.g., the nature of the activity; the degree of discretion involved). The current version of OMB Circular A-76 also explicitly defines commercial activity: A commercial activity is a recurring service that could be performed by the private sector and is resourced, performed, and controlled by the agency through performance by government personnel, a contract, or a fee-for-service agreement. A commercial activity is not so intimately related to the public interest as to mandate performance by government personnel. Commercial activities may be found within, or throughout, organizations that perform inherently governmental activities or classified work. Additionally, OMB Circular A-76 includes—but does not define—a category of activities that are commercial but "not appropriate for private sector performance." OMB Circular A-76 and its definition of inherently governmental function apply to all executive departments named in 5 U.S.C. §101 and all independent establishments as defined in 5 U.S.C. §104. There are no exemptions. However, OMB Circular A-76 repeatedly describes itself as a "policy" document, and expressly states that it "shall not be construed to create any substantive or procedural basis for anyone to challenge any agency action or inaction on the basis that such action or inaction was not in accordance with [the] Circular," with certain narrow exceptions involving appeals of cost comparisons and specific matters addressed in the FAIR Act. While OMB Circular A-76's characterization of itself in this manner is not necessarily dispositive of its legal effect, courts in some cases have found that OMB Circular A-76 is not the product of a congressional grant of legislative authority promulgated in accordance with any procedural requirements imposed by Congress, which is one of the requirements for a policy document to be seen as legally binding. In other cases, the courts have found that the plaintiffs lacked standing to challenge alleged violations of OMB Circular A-76 . It is worth noting, however, that OMB Circular A-76's definition of inherently governmental function is incorporated into the Federal Acquisition Regulation (FAR), as discussed below, and the FAR is generally seen to be legally binding. Issued on September 12, 2011, partly in response to the requirements of the National Defense Authorization Act for FY2009 ( P.L. 110-417 ), OFPP Policy Letter 11-01 constitutes the most recent guidance for federal agencies on inherently governmental and related functions. In several key places, Policy Letter 11-01 relies upon existing authorities. For example, rather than giving its own definition of "inherently governmental function," it adopts the FAIR Act's definition of an inherently governmental function as "one that is so intimately related to the public interest as to require performance by Federal Government employees." It also provides clarification and elaboration of this definition like that provided in the FAIR Act, noting, for example, that inherently governmental functions require "the exercise of discretion in applying Federal Government authority or the making of value judgments in making decisions for the Federal Government, including judgments relating to monetary transactions and entitlements." Similarly, the listings of inherently governmental functions and functions closely approaching inherently governmental functions provided in its Appendices mirror those in the Federal Acquisition Regulation (FAR), discussed below. Policy Letter 11-01 also expands upon existing authorities, however. For example, it establishes two new tests for identifying inherently governmental functions that agencies are required to use when considering whether particular functions may be contracted out. One is a "nature of the function" test, which categorizes functions involving the exercise of U.S. sovereign power as inherently governmental due to their "uniquely governmental nature," regardless of any "type or level of discretion associated with them." The other is an "exercise of discretion" test, which prohibits agencies from contracting out functions involving an exercise of discretion that would: commit[] the government to a course of action where two or more alternative courses of action exist and decision making is not already limited or guided by existing policies, procedures, directions, orders, and other guidance that: (I) identify specified ranges of acceptable decisions or conduct concerning the overall policy or direction of the action; and (II) subject the discretionary authority to final approval or regular oversight by agency officials. In addition, the policy letter requires agencies to take certain steps, before and after awarding a contract, to ensure that contractors do not come to perform inherently governmental functions. Before awarding a contract, agencies must review the listings of functions designated as inherently governmental in statute and the Appendices to Policy Letter 11-01 to ensure that their requirements do not entail the performance of inherently governmental functions, as well as analyze their requirements in light of the tests described above. Then, after awarding a contract, agencies must monitor both contractor performance and agency contract management. If monitoring reveals that contractors are performing inherently governmental functions, agencies are instructed to "reestablish control" over these responsibilities by strengthening oversight, insourcing the work, refraining from exercising options under the contract, or terminating all or part of the contract. Policy Letter 11-01 also establishes a definition of and guidance regarding "critical functions"—or functions "necessary to the agency being able to effectively perform and maintain control of its mission and operations" —that were previously lacking in federal law and policy. The policy letter requires that agencies ensure "federal employees perform and/or mange critical functions to the extent necessary for the agency to operate effectively and maintain control of its mission and operations." However, it would permit agencies to contract out critical functions provided that certain conditions are met (e.g., the agency determines in writing, prior to issuing a solicitation, that it has "sufficient internal capability" so that federal employees maintain control of missions and operations). The policy letter also expressly notes that functions deemed to be critical will differ among agencies, as well as within each agency over time. Finally, the policy letter provides certain guidance regarding functions closely associated with the performance of inherently governmental functions that was also previously lacking in federal law and policy. Pursuant to this guidance, before awarding a contract for a function closely associated with the performance of an inherently governmental function, the agency must determine in writing that it (1) has given special consideration to having federal employees perform the work; (2) has the resources to give "special management attention" to contract performance; and (3) will comply with the agency responsibilities laid out in Policy Letter 11-01. Similarly, after awarding the contract, the agency must regularly monitor both contractor performance and agency contract management, as it must do with critical functions. Policy Letter 11-01 applies to all "executive departments and agencies." Like OMB Circular A-76, Policy Letter 11-01 is a policy document that arguably lacks the force and effect of law. However, OFPP does appear to contemplate amending other authorities, including the Federal Acquisition Regulation (FAR), in light of Policy Letter 11-01. The key administrative law source on inherently governmental functions is the Federal Acquisition Regulation (FAR), which is the "primary document" in the Federal Acquisition Regulations System established for the "codification and publication of uniform policies and procures for acquisition by all executive agencies." Further declarations of specific functions as inherently governmental or commercial come from executive orders and GAO decisions construing executive branch regulations and guidance. In addition to the FAIR Act, OMB Circular A-76, and Policy Letter 11-01, the Federal Acquisition Regulation (FAR) is another source of federal law and policy on inherently governmental functions. Two subparts of the FAR—Subpart 7.3 on "contractor versus government performance" and Subpart 7.5 on "inherently governmental functions"—address such functions. Subpart 7.3 is designed to provide executive branch officials with procedures for contracting out those functions that were found to be appropriate for private-sector performance under OMB Circular A-76 or other authority. This subpart incorporates the definition of OMB Circular A-76 by reference and, like OMB Circular A-76, specifies that "[c]ontracts shall not be used for the performance of inherently governmental functions." Subpart 7.5, in contrast, is intended to ensure that "inherently governmental functions are not performed by contractors." It relies on a definition of inherently governmental function , contained in Subpart 2 of the FAR, which essentially mirrors the definition of OMB Circular A-76: "Inherently governmental function" means, as a matter of policy, a function that is so intimately related to the public interest as to mandate performance by Government employees. This definition is a policy determination, not a legal determination. An inherently governmental function includes activities that require either the exercise of discretion in applying Government authority, or the making of value judgments in making decisions for the Government. Governmental functions normally fall into two categories: the act of governing, i.e. , the discretionary exercise of Government authority, and monetary transactions and entitlements. (1) An inherently governmental function involves, among other things, the interpretation and execution of the laws of the United States so as to— (i) Bind the United States to take or not to take some action by contract, policy, regulation, authorization, order, or otherwise; (ii) Determine, protect, and advance United States economic, political, territorial, property, or other interests by military or diplomatic action, civil or criminal judicial proceedings, contract management, or otherwise; (iii) Significantly affect the life, liberty, or property of private persons; (iv) Commission, appoint, direct, or control officers or employees of the United States; or (v) Exert ultimate control over the acquisition, use, or disposition of the property, real or personal, tangible or intangible, of the United States, including the collection, control, or disbursement of Federal funds. (2) Inherently governmental functions do not normally include gathering information for or providing advice, opinions, recommendations, or ideas to Government officials. They also do not include functions that are primarily ministerial and internal in nature, such as building security, mail operations, operation of cafeterias, housekeeping, facilities operations and maintenance, warehouse operations, motor vehicle fleet management operations, or other routine electrical or mechanical services. However, Subpart 7.5 also goes beyond OMB-Circular A-76 by providing lengthy, but "not all inclusive," listings of (1) functions that are to be considered inherently governmental, and (2) functions that, although not inherently governmental, "may approach being in that category because of the nature of the function, the manner in which the contractor performs the contract, or the manner in which the Government administers contract performance." The former category includes direct control of criminal investigations, leadership of military personnel, conducting foreign relations, and directing and controlling federal employees. The latter category includes services involving or related to budget preparation, services in support of acquisition planning, participating as technical advisors on source selection boards, and serving as arbitrators or providing alternative methods of dispute resolution. Beyond the examples in these lists, the FAR provides none of the elaboration upon the meaning or identification of inherently governmental functions given by the FAIR Act, OMB Circular A-76, or OFPP Policy Letter 11-01. The FAR also provides no guidance upon "functions that approach being inherently governmental" beyond identifying them. In particular, it does not bar agencies from contracting out these functions, and at least one federal court decision suggests that agencies may contract for the performance of functions closely associated with inherently governmental functions. The FAR's provisions on inherently governmental functions and functions approaching inherently governmental functions generally apply to all executive branch agencies not specifically exempted from the FAR. However, Subpart 7.5 does not apply to services obtained through personnel appointments, advisory committees, or personal services contracts issued under statutory authority. A personal services contract is "a contract that, by its express terms or as administered, makes the contractor personnel appear to be, in effect, Government employees." As a regulation promulgated through notice-and-comment procedures, the FAR is generally legally binding. However, agencies are expressly authorized to deviate from the FAR on a contract-specific or "class" basis provided that certain conditions are met. Executive orders have also been used to designate certain functions as inherently governmental or commercial. For example, Executive Order 13180, issued by President Clinton on December 7, 2000, designated the "provision of air traffic services" as an inherently governmental function. This order was effectively repealed by Executive Order 13264, issued by President George W. Bush on June 4, 2002, which removed the language designating provision of air traffic services as an inherently governmental function from its discussion of such services. There do not appear to be other such designations presently in effect. Numerous GAO decisions have also addressed the designation of specific functions as inherently governmental or commercial. GAO comes to address this question in two contexts: (1) in issuing advisory opinions, requested by agency officials, addressing whether agencies' proposed uses of appropriated funds are permissible and (2) in deciding bid protests when a protester challenges agencies' proposed contracting out of allegedly inherently governmental functions. GAO's decisions in bid protests lack the force of law and do not bind federal agencies or protesters. Moreover, in neither context does GAO offer its own definition of inherently governmental functions. Rather, GAO uses a test for identifying inherently governmental functions that is based heavily on OMB Circular A-76 and the FAR. In part because GAO focuses on executive branch sources in identifying inherently governmental functions, its decisions are discussed here, instead of with federal court decisions, in the following section. GAO's test of inherently governmental functions looks for (1) the exercise of substantial discretionary authority by government contractors, or (2) the contractor's making value judgments on the government's behalf. Both are factors mentioned along with the definitions of inherently governmental functions in the FAIR Act and OMB Circular A-76 and illustrated by the examples in the FAR. For example, in its decision in NRC Contracts for Reactor Licensing Tests , GAO applied this test to the Nuclear Regulatory Commission's (NRC's) proposal to contract out some of its functions in administering licensing tests for nuclear reactor operators. Under the proposed contract, the contractor would have prepared, administered, and graded the tests, as well as provided the NRC with recommendations on which candidates should be granted licenses. GAO found that the proposed contract did not involve inherently governmental functions because the NRC guidelines relating to the tests provided "such extensive detail and guidance" that the contractors had no opportunity to exercise discretion or make value judgments in preparing, administering, or grading the tests. GAO also emphasized that agency personnel—not the contractor—would ultimately decide who received licenses. When emphasizing ultimate agency decision making, GAO highlighted a further distinction between performing a function and advising or assisting with a function that GAO and the courts sometimes also use when identifying inherently governmental functions. GAO's decision in the Matter of GSA Transportation Audit Contracts similarly illustrates another characteristic of GAO decisions addressing whether specific functions are inherently governmental. In this case, the General Services Administration (GSA) proposed to contract out seven functions it had formerly performed in-house when conducting transportation audits. Based upon GSA's descriptions of the proposed contracts, GAO ultimately found that two of these functions were inherently governmental, two were commercial, and the remaining three were not clearly inherently governmental or commercial. As this decision illustrates, GAO examines the context of contractual performance, including the degree of actual supervision that agencies exercise over contractors allegedly performing inherently governmental functions. It generally does not classify functions as inherently governmental or commercial in the abstract. Among the functions that GAO has classified as inherently governmental, at least in certain circumstances, are: requesting set-off actions against transportation carriers; communicating with U.S. attorneys to request collection actions against delinquent transportation carriers; the functions of the organization head, contracting officer, and supply branch; serving as an agency hearing officer; preparing congressional testimony on behalf of an agency; performing legally required audit tasks; deciding to accept or reject a particular candidate for a program; approving departures from policy and guidance in issuing certifications; certifying new or unproven technologies; determining what constitutes a standard of safety equivalent to a required standard; finding the existence of special conditions or exceptions; making preemptive or other attacks; and determining individuals' suitability for employment or eligibility for security clearances. GAO has similarly recognized the following functions as commercial, at least in certain contexts: identifying overcharges related to billing above established audit minima; sending notices of overcharges or other notices; collecting user fees in national forests; answering an agency hotline where the answers do not involve interpretation of laws or regulations; examining vouchers, verifying invoice accounts and identifying billing errors; administering programs in accordance with agency regulations and policy; writer-editor services in preparing statements or testimony where the government's position is established; property accountability, forecasting, programming and budgeting; examination, inspection, and testing services necessary to issue certifications; provision of guard or protective services; and gathering and reporting information on investigations. Federal courts have also addressed the question of whether specific functions are inherently governmental or commercial. Two contexts typically prompt courts to determine what is an inherently governmental function. The first context involves litigation under the FAIR Act, OMB Circular A-76, and the FAR. This context actually entails a smaller number of published decisions than the second context, which involves litigation concerning constitutional rights. The litigation concerning constitutional rights itself can take two forms. First, there are cases involving the "state action doctrine," which consider whether private actors are performing inherently governmental functions in determining (1) whether those actors must provide the same constitutional rights to third parties that the government must provide, and (2) whether those actors can claim sovereign immunity for certain actions like government officials can. Second, there are cases involving the "private delegation doctrine," which center upon whether a private party was given impermissible authority to legislate or make rules on the government's behalf. Legislating and rulemaking are inherently governmental functions. The courts, like GAO, do not have an independent definition of inherently governmental functions. In deciding cases under the FAIR Act or other authorities, the courts use the definitions provided in these sources. Moreover, in at least some such cases, courts give considerable deference to the executive branch's classification of a function as inherently governmental or commercial because of the political question doctrine, under which courts decline to hear issues that have been entrusted to the discretion of another branch of government and that lack judicially discoverable and management standards for their resolution. In Arrowhead Metals, Ltd. v. United States , for example, the court categorized the coinage of money as inherently governmental because it is one of the powers that the Constitution grants to Congress. However, the court also found that the U.S. Mint has discretion to determine whether the stamping of blanks constitutes coinage. In reaching this conclusion, the court noted its "desire to avoid a legislative-executive controversy" regarding whether the striking of blanks in the production of coins constitutes an inherently governmental function. In other cases not involving the FAIR Act or specific provisions of procurement law or policy, the courts use a test of inherently governmental functions much like that used by GAO, focusing upon the degree to which a private party exercises substantial discretion, or makes judgments, on the government's behalf. Functions classified as inherently governmental under the constitutional test include: conducting elections; exercising the power of eminent domain; providing police services; investigating allegations of child abuse; exercising prosecutorial discretion; chartering, oversight, and regulation of companies; creation of public monopolies; holding the personal property of prisoners; limiting the First Amendment rights of prisoners; taxing and paying governmental indebtedness or obligations; devising tariff regimes; and hiring diplomatic staff or civil servants. Functions categorized as commercial, in contrast, include providing transportation services to citizens , and selling government land on the government's behalf. Designations of specific functions as inherently governmental in judicial decisions have the force of law, at least within the jurisdictions where the decisions are precedent and for so long as the decisions are not overturned. However, a judicial declaration that a function is inherently governmental under a constitutional test would not necessarily preclude the executive branch from contracting out this function under the FAIR Act, OMB Circular A-76, the FAR, or OFPP Policy Letter 11-01. Rather, in the "state action" context, the designation of a function as inherently governmental means only that the contractor performing the inherently governmental function (1) owes private individuals the same constitutional rights that the government owes them and (2) can potentially claim sovereign immunity like government officials can. Similarly, in the "private delegation" context, the designation means only that any regulations issued by the contractor cannot be constitutionally applied to private individuals. The "private delegation" doctrine would not necessarily preclude the contractor from performing other functions under the contract that resulted in the contractor's issuance of the regulations. In sum, the various authorities discussed herein differ somewhat in their treatment of inherently governmental and other functions. The primary differences between them are arguably not in their definitions of inherently governmental function , however, as Table 1 illustrates. Rather, the key differences are in their provisions elaborating and expanding on the definition of inherently governmental functions, provisions which arguably reflect the source's intended purpose and use, not differing conceptions of what constitutes an inherently governmental functions. For example, OMB Circular A-76, which "establishes federal policy for the competition of commercial activities," includes a definition and discussion of commercial services that is not found in other sources. Similarly, OFPP Letter 11-01, which is designed to "assist agency officers and employees in ensuring that only Federal employees perform work that is inherently governmental or otherwise needs to be reserved to the public sector," includes a definition of critical functions and tests for identifying inherently governmental functions, among other things, not found in other sources. 

Summary: Functions that federal law and policy require to be performed by government personnel, not contractor employees, are known as "inherently governmental functions." Such functions have been a topic of interest in recent Congresses, in part, because of questions about sourcing policy (i.e., whether specific functions should be performed by government personnel or contractor employees). There have also been questions about the various definitions of inherently governmental function given in federal law and policy and, particularly, whether the existence of multiple definitions of this term may have resulted in contractor employees performing functions that should be performed by government personnel. Two primary definitions of inherently governmental function currently exist in federal law and policy. One is a statutory definition, enacted as part of the Federal Activities Inventory Reform (FAIR) Act of 1998. This definition states that an inherently governmental function is "a function so intimately related to the public interest as to require performance by Federal Government employees." The other is a policy-oriented definition contained in Office of Management and Budget (OMB) Circular A-76. This definition states that an inherently governmental activity is "an activity that is so intimately related to the public interest as to mandate performance by government personnel." These two definitions arguably do not differ significantly in and of themselves. However, both the FAIR Act and OMB Circular A-76 include further elaboration and expansion upon the meaning of inherently governmental function that differ in certain ways. Other statutes, regulations, and guidance documents that define inherently governmental function do so either by reproducing the language of the FAIR Act or OMB Circular A-76, or by incorporating their definitions by reference. Most notably, the Federal Acquisition Regulation (FAR) incorporates by reference or otherwise adopts the definition of OMB Circular A-76, while Office of Federal Procurement Policy (OFPP) Policy Letter 11-01, discussed below, adopts the FAIR Act's definition. However, like the FAIR Act and OMB Circular A-76, both the FAR and Policy Letter 11-01 also include some unique elaboration and expansion upon the term. In addition to these definitions, there are numerous statutory, regulatory, and policy provisions designating specific functions as inherently governmental or, alternatively, commercial. (A commercial function is one that could be performed by contractor employees, although there is generally no requirement that contractor employees perform commercial functions.) Such designations also help establish the meaning of inherently governmental function by specifying what is—and is not—included within this category. Similarly, while not offering their own definitions of inherently governmental function, the Government Accountability Office (GAO) and the federal courts have developed tests that they use in identifying specific functions as inherently governmental or commercial. However, a judicial declaration that a particular function is inherently governmental under a constitutional test would not necessarily preclude the executive branch from contracting out this function. The 110th Congress tasked OMB with reviewing existing definitions of inherently governmental function and developing a "single consistent definition" of this term. Partly in response to this charge, OMB, though the OFPP, issued Policy Letter 11-01. Policy Letter 11-01 adopts the FAIR Act's definition of inherently governmental function, rather than establishing a new definition. However, Policy Letter 11-01 does establish two tests for identifying inherently governmental functions, as well as defines a critical function as one "that is necessary to the agency being able to effectively perform and maintain control of its mission and operations."
