Opinion for the Court filed by Circuit Judge ROGERS.
Contending that the district failed to follow the procedures set forth in
Kimbro v. Velten,
I.
According to the complaint’s factual allegations, which this court accepts as true,
Sturm, Ruger & Co. v. Chao,
Stokes challenged the Notice as “false and malicious or made with reckless disregard for the truth,” and GPO canceled the Notice. Stokes also filed a complaint in the Superior Court of the District of Columbia, alleging that the seven co-workers not only failed reasonably to investigate the incident in good faith and to interview critical eyewitnesses, but also destroyed and ignored critical evidence, including video and audio tapes that would have exonerated Stokes. Specifically, Stokes alleged that Lieutenant Steven Cross and Commander James C. Raysinger, Stokes’ superiors, induced the participation of Manuel Rivera, Phillip Griffin, and Collins Bailey, Jr., Stokes’ subordinates, to manufacture false statements in support of the Notice. He further alleged that they had threatened Corporal Sherman Gray’s career and livelihood if he did not make a statement adverse to Stokes; Gray executed a statement prepared by Griffin and Rivera but later recanted it. The defendants’ actions, Stokes claimed, were designed to prevent his promotion, as it was well known that he intended to apply for the position of his supervisor, who had recently announced his plans to retire. Stokes alleged that he was “a leading and an extremely well-qualified candidate” for the position because of his seniority and “unblemished employment performance history.” “[D]ue to spite, malice and ill-will and other sinister reasons,” he claimed, the defendants sought to besmirch his record and foil his promotion opportunity by “orchestrat[ing] a conspiracy to injure, defame, harm, or destroy” his professional reputation.
On motion of three defendants the case was removed to United States district court. 28 U.S.C. §§ 1441, 1442(a)(1), & 1446 (2000). In the district court, Assistant United States Attorney (“AUSA”) Mark E. Nagle, by authority delegated to and by the United States Attorney, filed a certification stating that “C. Steven Cross, Raymond Garvey, James C. Raysinger, William Wilson, and Collins Bailey, Jr. were acting within the scope of their authority as employees of the United States at the time of [the] alleged incidents.” AUSA Nagle later filed a second certification stating that Griffin and Rivera were acting within the scope of their employment.
At a status call, the district court considered AUSA Nagle’s certification to be “pri-ma facie evidence” on the scope-of-employment issue and stated that Stokes had “given no evidence to suggest that Mr. Nagle is not able to make the certification that he has.” The court therefore substituted the United States as defendant and, because the United States had not waived its immunity from defamation claims, 28 U.S.C. § 2680(h) (2000), dismissed Stokes’ claims against the five defendants named in the AUSA’s first certification. After receiving the second certification, the *1213 court, sua sponte, dismissed the remaining claims.
II.
In
Westfall v. Erwin,
The Supreme Court has held that the government’s scope of employment determination under the Westfall Act is judicially reviewable regarding the substitution of the government.
Gutierrez de Martinez v. Lamagno,
This circuit had reached the same conclusion a year earlier in
Kimbro,
which held that “[rjegardless of the content of the certification ... the federal district
*1214
court must at least conduct an evidentiary hearing on the scope issue.” 30 F.Bd at 1508. “If there is a material dispute as to the scope issue,” the court said, “the district court must resolve it at an evidentiary hearing.”
Id.
at 1509. “[T]his procedure,” the court continued, is “in keeping with the statutory seheme[, which] does not really treat the certification as having any particular evidentiary weight....”
Id.
The court also considered the weight to which the government’s certification is entitled, adopting the approach of the Third Circuit.
Id.
at 1509. In
Melo v. Hafer,
[i]f the Attorney General’s certification is based on a different understanding of the facts than is reflected in the complaint, the plaintiff should be permitted reasonable discovery and should then be called upon to come forward, as if responding to a motion for summary judgment, with competent evidence supporting the facts upon which he would predicate liability, as well as any other facts necessary to support a conclusion that the defendant acted beyond the scope of his employment.
Id.
at 747;
Kimbro,
is not conclusive regarding substitution of the federal government. Instead, the federal court may determine independently whether the employee acted within the scope of employment and, therefore, whether to substitute the federal government as the proper defendant.
Haddon v. United States,
Other circuits have agreed that a plaintiff challenging the government’s scope-of-employment certification “bears the burden of coming forward with specific facts rebutting the certification,” and that the question of scope of employment is governed by state law.
Lawson v. United States,
Upon
de novo
review of the district court’s dismissal of Stokes’ complaint pursuant to Rules 12(b)(1), 12(b)(2), and 12(b)(6) of the Federal Rules of Civil Procedure,
Sturm, Ruger & Co.,
The district court misapprehended the law regarding scope-of-employment certifications. Stokes’ burden was not to show that AUSA Nagle lacked the authority to issue the certification. Stokes understandably has never challenged that authority.
See
28 U.S.C. § 2679(d); 28 C.F.R. § 15.3(a). Instead, Stokes’ burden was to raise a material dispute regarding the substance of AUSA Nagle’s determination by alleging facts that, if true, would establish that the defendants were acting outside the scope of their employment.
See Kim-bro,
Stokes’ complaint contains sufficient factual allegations to warrant discovery on the question of scope of employment. Rule 8’s liberal pleading standard requires only “a short and plain statement of the claim showing that the pleader is entitled to relief,” Fed.R.Civ.P. 8(a)(2), and courts are charged with construing the complaint “so ... as to do substantial justice,” Fed.R.Civ.P. 8(f). The Rules “do not require a claimant to set out in detail the facts upon which he bases his claim.”
Conley v. Gibson,
Consequently, to obtain discovery and an evidentiary hearing, Stokes need only have alleged sufficient facts that, taken as true, would establish that the defendants’ actions exceeded the scope of their employment. The scope issue is governed by District of Columbia law, which looks to the Restatement (Second) of Agency (1958) in defining scope of employment.
Haddon,
[cjonduct of a servant is within the scope of employment if, but only if: [a] it is of the kind he is employed to perform; [b] it occurs substantially within the autho *1216 rized time and space limits; [c] it is actuated, at least in part, by a purpose to serve the master; and [d] if force is intentionally used by the servant against another, the use of force is not unexpectable by the master.
Restatement (Second) of Agency § 228(1). “Conduct of a servant is not within the scope of employment if it is ... too little actuated by a purpose to serve the master.”
Id.
§ 228(2). The District of Columbia’s formulation of this test “excludes from the scope of employment all actions committed ‘solely for [the servant’s] own purposes.’ ”
Weinberg v. Johnson,
The government contends that the defendants’ conduct was within the scope of their employment because it was incidental to their duty to investigate and report officers who fail to render assistance. Stokes contends, however, that the defendants’ alleged conduct — destroying critical evidence, preparing and submitting false affidavits by use of threat and coercion, and engaging in other criminal acts — falls outside the scope of their employment. It is unclear whether evidence of such conduct alone would be sufficient under District of Columbia law, which liberally construes the doctrine of respondeat superior, at least with respect to the first prong of the Restatement (Second) of Agency § 228(1).
See Haddon,
Not every complaint will warrant further inquiry into the scope-of-employment issue. In
Singleton,
Accordingly, because the district court deviated from the Kimbro approach by essentially affording conclusive weight to the AUSA’s scope-of-employment certifications and failing to consider whether Stokes’ allegations entitled him to discovery, we reverse. On remand, the district court shall allow Stokes to conduct at least limited discovery on the scope-of-employment issue.
