delivered the opinion of the Court.
Rеspondent William Erwin and his wife respondent Emely Erwin brought a state-law tort suit against petitioners, federal employees in the Executive Branch, alleging that he had suffered injuries as a result of petitioners’ negligence in performing official acts. The issue presented is whether these federal officials are absolutely immune from liability under state tort law for conduct within the scope of their employment without regard to whether the challenged conduct was discretionary in nature.
I
Respondents William and Emely Erwin commenced this tort action in statе court. At the time of the alleged tort, William Erwin was employed by the Federal Government as a civilian warehouseman at the Anniston Army Depot in Anniston, Alabama. Petitioners were supervisors at the Depot. 1 Respondents’ complaint alleged that while working at the Depot William Erwin came into contact with bags of *294 toxic soda ash that “were improperly and negligently stored.” 1 Record, Complaint ¶ 3. The complaint stated that William Erwin suffered chemical burns to his eyes and throat when he inhaled soda ash dust that had spilled from its bag. William Erwin also asserted that the soda ash “should not have been routed to the warehouse where [he] was working,” and that “someone should have known that it was there and provided [him] with some warning as to its presence and danger before [he] inhaled it.” 1 Record, Doc. No. 4, p. 1. The complaint сharged petitioners with negligence “in proximately causing, permitting, or allowing [him] to inhale the . . . soda ash.” 1 Record, Complaint ¶6.
Petitioners removed the action to the United States District Court for the Northern District of Alabama pursuant to 28 U. S. C. § 1442(a)(1). The District Court held that petitioners were absolutely immune from suit and granted summary judgment in their favor. After finding that the alleged tort was committed while petitioners were acting within the scope of their employment, the court held that “any federal employee is entitled to absolute immunity for ordinary torts committed within the sсope of their jobs.” Civ. Action No. CV85-H-874-S, p. 2 (June 5, 1985). The Court of Appeals reversed, reasoning that a federal employee enjoys immunity “ ‘only if the challenged conduct is a discretionary act
and
is within the outer perimeter of the actor’s line of duty.’ ”

Petitioners initially ask that we endorse the approach followed by the Fourth and Eighth Circuits, see
General Electric Co.
v.
United States,
The central purpose of official immunity, promoting effective government, would not be furthered by shielding an official from state-law tort liability without regard to whether the alleged tortious conduct is discretionary in nature. When an official’s conduct is not the product of independent judgment, the threat of liability cannot detrimentally inhibit *297 that conduct. It is only when officials exercise decisionmaking discretion that potential liability may shackle “the fearless, vigorous, and effective administration of policies of government.” Barr v. Matteo, supra, at 571. Because it would not further effective governance, absolute immunity for non-discretionаry functions finds no support in the traditional justification for official immunity.
Moreover, in Doe v. McMillan, supra, we explicitly rejected the suggestion that official immunity attaches solely because conduct is within the outer perimeter of an official’s duties. Doe involved a damages action for both constitutional violations and common-law torts against the Public Printer and the Superintendent of Documents arising out of the public distribution of a congressional committee’s report. After recognizing that the distribution of documents was “ ‘within the outer perimeter’ of the statutory duties of the Public Printer and the Superintendent of Documents,” the Court stated: “[I]f official immunity automatically attaches to any conduct expressly or impliedly authorized by law, the Court of Appeals correctly dismissed the complaint against these officials. This, however, is not the governing rule.” Id., at 322. The Cоurt went on to evaluate the level of discretion exercised by these officials, finding that they “exercise discretion only with respect to estimating the demand for particular documents and adjusting the supply accordingly. ” Id., at 323. The Court rejected the claim that these officials enjoyed absolute immunity for all their official acts, and held instead that the officials were immune from suit only to the extent that the Government officials ordering the printing would be immune for the same conduct. See id., at 323-324. The key importance of Doe lies in its analysis of discretion as a critical factor in еvaluating the legitimacy of official immunity. As Doe’s analysis makes clear, absolute immunity from state-law tort actions should be available only when the conduct of federal officials is within the scope *298 of their official duties and the conduct is discretionary in nature. 4
As an alternative position, petitioners contend that even if discretion is required before absolute immunity attaches, the requirement is satisfied as long as the official exercises “minimal discretion.” Brief for Petitioners 15. If the precise conduct is not mandated by law, petitioners argue, then the act is “discretionary” and the official is entitled to absolute immunity from state-law tort liability. We reject such a wooden interpretation of the discretionary function requirement. Because virtually all official acts involve some modicum of choice, petitioners’ reading of the requirement would render it essentially meaninglеss. Furthermore, by focusing entirely on the question whether a federal official’s precise conduct is controlled by law or regulation, petitioners’ approach ignores the balance of potential benefits and costs of absolute immunity under the circumstances and thus loses sight of the underlying purpose of official immunity doctrine. See
Doe
v.
McMillan,
*299
In the present case, the Court of Appeals, reviewing a summary judgment determination, held that petitioners were not entitled to official immunity solely because they were acting within the scope of their official duties, and that there was a material question whether the challenged conduct was discretionary.
Because this case comes to us on summary judgment and the relevant factual background is undeveloped, we are not called on to define the precise boundaries of official immunity or to determine the level of discretion required before immunity may attaсh. In deciding whether particular governmental functions properly fall within the scope of absolute official immunity, however, courts should be careful to heed the Court’s admonition in Doe to consider whether the contribution to effective government in particular contexts outweighs the potential harm to individual citizens. Courts must not lose sight of the purposes of the official immunity *300 doctrine when resolving individual claims of immunity or formulating general guidelines. We are also of the view, however, that Congress is in the best position to provide guidance for the сomplex and often highly empirical inquiry into whether absolute immunity is warranted in a particular context. Legislated standards governing the immunity of federal employees involved in state-law tort actions would be useful.
Ill
The Court of Appeals was correct in holding that absolute immunity dоes not shield official functions from state-law tort liability unless the challenged conduct is within the outer perimeter of an official’s duties and is discretionary in nature. Moreover, absolute immunity does not attach simply because the precise conduct of the federаl official is not prescribed by law. There is thus a genuine issue of material fact as to whether petitioners’ conduct is entitled to absolute immunity. Accordingly, the judgment of the Court of Appeals is affirmed.
It is so ordered.

v.
United States,
In determining the propriety of shielding an official from suit under the circumstances, this Court has long favored a “functional” inquiry — immunity attaches to particular official functions, not to particular offices. See,

We recognize that the plurality opinion in
