An "inherently governmental function" is one that, as a matter of law and policy, must be performed by federal government employees and cannot be contracted out because it is "intimately related to the public interest." Concerned that the existence of multiple and/or inconsistent definitions of "inherently governmental functions" might be partly responsible for the alleged contracting out of inherently governmental functions by the Department of Defense (DOD) and other agencies, the 110th Congress enacted legislation (P.L. 110-417) requiring the Office of Management and Budget (OMB) to develop a "single consistent definition" of "inherently governmental functions." This definition is to "ensure that the head of each ... agency is able to identify each position within that department or agency that exercises an inherently governmental function." Congress has several options if it is concerned that deficiencies in the existing definitions of inherently governmental functions may lead agencies to improperly contract out inherently governmental functions. Options include (1) relying upon recent statutory changes and/or the policies of the Obama Administration, which proposes to limit contracting out generally, to effect desired changes in agency contracting; (2) changing the existing definition of "inherently governmental functions"; (3) placing limits on contracting out or use of appropriated funds; (4) addressing structural factors potentially prompting agencies to rely on contractors; (5) providing for more effective oversight of executive branch contracting decisions; and (6) focusing more on questions of contracting policy (i.e., what functions should the government perform?) than on contracting law (i.e., what functions must the government perform?).
