¶1*636Mr. O. E. Jones, Washington, D. C., for appellant.
¶2No brief for appellee. Messrs. James A. Washington, Jr., and Frank D. Reeves, Washington, D. C., entered appearances for appellee.
¶3Before EDGERTON, PRETTYMAN and DANAHER, Circuit Judges.
¶5The late Clinton M. Irvine while in the course of his employment as a custodian at Howard University was so injured by an explosion of chemicals that he died on March 27, 1952. Surviving were his widow, Edith Irvine, and his mother, Nancy Irvine. The decedent left no estate other than a possible cause of action for his wrongful death. See D.C. Code, § 16-1201 (1951). The decedent’s mother consented to the appointment of the petitioner, decedent’s aunt, as admin-istratrix of the decedent’s estate, apparently on the theory that the estate has a valid claim against Howard University which the widow is unwilling to assert. Decedent’s widow contested petitioner’s application, and actually opposed the appointment of any administratrix but claimed that if one were to be appointed,' she, as the widow, should be named. The District Court, sitting as a court of probate, did not rule on the widow’s claim to-possible appointment but denied petitioner’s application for appointment as such, administratrix. This appeal followed.
¶6Following Irvine’s death, his widow, in-an administrative proceeding before the Bureau of Employees’ Compensation of the Department of Labor, received am award under the Federal Employees’ Compensation Act.1 If decedent was an-employee of the United States or of Howard University as an “instrumentality”' of the United States, the liability under the Act was exclusive, and neither the United States nor its instrumentality could be liable in a separate action.2 Posey v. Tennessee Valley Authority, 5 Cir., 1937, 93 F.2d 726. If decedent were not. an employee of the United States but of Howard University, and if Howard University were not an “instrumentality” of the United States, the Federal Employees’ Compensation Act would not apply.3
¶7There is no record before this Court upon which we can determine that Irvine was an employee of a private institution-rather than of the federal government.. For all that appears, the Bureau found that decedent was in the employ of the Federal Security Agency,4 and that he received his compensation from the United States Government. The Bureau might have found that he was a federal *637employee but that for the performance of his duties, he was simply assigned to Howard University. The Bureau may have concluded that Howard University is not an instrumentality of the United States and that it is not enough that the University is the recipient of an annual federal appropriation, and in some degree is under jurisdiction of the Department of Health, Education and Welfare. See 20 U.S.C.A. § 121 et seq., and Reorg. Plan No. 1 of 1953, 5 U.S.C.A. following section 623. See also, Maiatico Construction Co. v. United States, 1935, 65 App.D.C. 62, 79 F.2d 418, certiorari denied U. S. to use of Phelps v. Maiatico Const. Co., 1935, 296 U.S. 649, 56 S.Ct. 309, 80 L.Ed. 462.
¶8Petitioner argued to the District Court and urges here that a cause of action lies against Howard University as a third party wrongdoer responsible for the death of the decedent Irvine. Had the status of Irvine been questioned before the Bureau of Employees’ Compensation, it would have been necessary for the Bureau to determine whether he was an employee of Howard University as a private institution and not within the Act, or whether he was an employee of the United States or of an instrumentality of the United States. In Lewis v. United States, 1951, 89 U.S.App.D.C. 21, 190 F.2d 22, certiorari denied, 1951, 342 U.S. 869, 72 S.Ct. 110, 96 L.Ed. 653, this Court said: “The coverage of [Federal Employees’ Compensation] Act is … left to the primary determination of the agency administering it.”
¶9The petitioner, so far as the record shows, presented no challenge to the administrative determination that the deceased was a federal employee and that decedent’s widow was entitled to compensation under the Act.5 Apparently the Bureau of Employees’ Compensation so found, for an award was made to the widow under the Act. Again, the District Court, sustaining the Bureau’s determination, held that: “the alleged claim of petitioner that a cause of action for [intestate’s] death exists in his estate under the provisions of the Wrongful Death Statute of the District of Columbia (Tit. 16, § 1201 D.C. Code) is without merit in view of the applicability of the [Federal Employees’ Compensation Act] …
¶10Upon the record thus presented, the judgment of the District Court will be
¶11Affirmed.
