held that the unpublished manual, promulgated in accordance with the relevant executive order and statute, was binding on the Department.
Id. at 374-76, 77 S.Ct. at 1158-59. Similarly, in
Vitarelli v. Seaton, 359 U.S. 535, 538-40, 79 S.Ct. 968, 971-73, 3 L.Ed.2d 1012 (1959), the Court held that the Department of Interior was required to comply with the procedural standards set forth in an internal order before dismissing an employee, even though in the absence of such standards the employee could have been dismissed summarily. The Court treated the provisions of the informal order as “regulations.”
Id. at 539-40, 79 S.Ct. at 972-73. Moreover, in
Thorpe v. Housing Authority of Durham, 393 U.S. 268, 274-76, 89 S.Ct. 518, 522-23, 21 L.Ed.2d 474 (1969), the Court held that a circular distributed by the Department of Housing and Urban Development (HUD) was binding on the Department since the circular was issued pursuant to the agency’s general rule-making powers and was intended by the agency to be mandatory. The Court evaluated the circular as “an administrative regulation.”
Id. at 276, 89 S.Ct. at 523.
In Piccone, 407 F.2d at 871-72, the court held that a government employee’s removal was invalid because provisions of the Navy Civilian Personnel Instructions had been violated. In his concurrence, Judge Nichols directly confronted the issue of whether an unpublished (i.e., not promulgated under the procedures set forth in the APA) manual or document of a government agency could be considered a “regulation.” He stated that “whether [any piece of paper emanating from an agency] is a regulation would seem to depend in part on its contents and in part on agency intent ascertained by extrinsic evidence.” Id. at 877 (Nichols, J., concurring). Additionally, in Doe v. Hampton, 566 F.2d 265, 280-81 (D.C.Cir.1977), the court held that provisions of the Federal Personnel Manual may be binding on the Government if the author of the manual so intended, even if the manual was not published in the Federal Register. The intent of the promulgator should be ascertained by an examination of the provision’s language, its context, and any available extrinsic evidence. Id. at 281.
In contrast, other court decisions have held that a provision of a manual or handbook is not a regulation that would be binding on the Government. In Khuri v. United States, 154 Ct.Cl. 58, 1961 WL 8723 (1961), the court held that provisions of the Foreign Service Manual were not binding on the Government. Although the court considered the provisions to be “regulations,” the court determined that the Department of State did not intend the manual to be mandatory, but rather intended it to be a guide, setting forth general policies and principles. Id. at 64. Similarly, in Caterpillar Tractor Co. v. United States, 589 F.2d 1040,1043, 218 Ct.Cl. 517 (1978), the court held that a Department of Treasury handbook for exporters constituted “interpretive regulations” and, thus, was not binding on the Government. The court in Fiorentino v. United States, 607 F.2d 963, 968-69, 221 Ct.Cl. 545 (1979), found that a provision of a HUD employee manual was not a binding regulation because it contravened a statute. In Donovan v. United States, 433 F.2d 522, 523-24 (D.C.Cir.1970), the court determined that certain provisions of the unpublished Federal Aviation Administration employee handbook were advisory and not mandatory and, thus, not binding.
Indeed, this court has, on several occasions, stated that provisions of the Federal Personnel Manual (FPM) were not binding regulations. In Griessenauer v. Department of Energy, 754 F.2d 361, 364 (Fed.Cir.1985), we found that a provision of the FPM, which stated that an employee’s resignation “should” be by written resignation, was prec-atory and not mandatory. We held that this provision and similar provisions of the FPM “do not create any rights in an employee,” and are not binding on the Government. Id. See also Collins v. Merit Sys. Protection Bd., 978 F.2d 675, 678 (Fed.Cir.1992). Similarly, in Johnson v. Merit Systems Protection Board, 812 F.2d 705, 711 (Fed.Cir.1987), we held that a provision of the FPM, which stated that an agency “should make every effort to take back a former employee who was retired for disability,” “merely establishes a ‘policy’ for agencies to follow” and “does not create any rights in the [employee].” In Horner v. Acosta, 803 F.2d 687, 694-95 (Fed.Cir.1986), we refused to give
