Opinion for the court filed by Circuit Judge J. SKELLY WRIGHT.
J. SKELLY WRIGHT, Circuit Judge:
The Department of Labor’s Benefits Review Board hears appeals from decisions of Administrative Law Judges (ALJs) concerning claims for federal workers’ compensa-^ tion brought pursuant to the Longshoremen’s and Harbor Workers’ Compensation Act of 1927, 44 Stat. 1424, as amended, 33 U.S.C. § 901 et seq. (1976 & Supp. IV 1980). The Act expressly authorizes the Secretary of Labor to appoint the three members of the Board, 33 U.S.C. § 921(b)(1) (1976), but is silent concerning the members’ tenure and the terms of their removal. Contemporaneously with creation of the Board, the Secretary promulgated regulations providing that Board members would serve indefinite terms at his discretion. 20 C.F.R. § 801.201(d) (1982). This regulation remained unchallenged for almost a decade.
In May of 1982 the Secretary attempted to remove two members of the Board without specifying his reasons or providing them with a hearing.1 The removed members brought suit in the District Court to enjoin the Secretary from removing them. The District Court awarded the re[139]*139quested injunctions. Although it found that the Board was not an Article III court and therefore that the Board members were not entitled to Article Ill’s guarantee of life tenure, the District Court held that Board members could not be removed without a showing of cause because Congress intended for the Board to have an independent and quasi-judicial status. We agree that the Board is not an Article III court. But because we find that Congress did not intend to make the Board independent of the Secretary, we reverse the District Court’s judgment enjoining the Board members’ removal. We hold to the longstanding rule that in the face of congressional silence all inferior officers of the United States serve at the discretion of their appointing officer.
I.Background
The Longshoremen’s and Harbor Workers’ Compensation Act provides workers’ compensation for certain workers not covered by state workers’ compensation schemes.2 The Act makes employers liable up to a statutory maximum for job-related injuries and deaths without regard to fault. 33 U.S.C. § 904 (1976). If a dispute regarding a claim arises, a deputy commissioner of the Department of Labor will seek to resolve it through informal means.3 20 C.F.R. § 701.311-701.319 (1982). If informal resolution is not possible, the deputy commissioner will transfer the dispute to an ALJ. 33 U.S.C. § 919(d) (1976 & Supp. IV 1980). The ALJ will conduct a formal hearing according to the Administrative Procedure Act, 5 U.S.C. §§ 500-576 (1976 & Supp. V 1981),4 and has the power to approve settlements of disability,5 to approve withdrawal of claims,6 and to issue compensation orders.7 Interested parties may file appeals from the ALJ’s decision with the Board,8 and from the Board with the appropriate Court of Appeals.9 33 U.S.C. §§ 921(b) & (c) (1976 & Supp. IV 1980).
Prior to the Act’s amendment in 1972, deputy commissioners adjudicated disputed claims—conducting hearings and receiving [140]*140evidence, 44 Stat. 1435, as well as administering the Act. Their initial decisions were then reviewable by the District Courts, with further resort, if desired, to the Courts of Appeals.10 The 1972 amendments completely overhauled the procedures necessary to obtain benefits under the Act.11 The amendments left the initial informal resolution of claims to the deputy commissioners,12 but transferred the formal adjudication of claims to the ALJs and the Board.13 The amendments thus completely eliminated the role of the District Courts in the claims process, though, of course, resort to the Courts of Appeals was maintained.
Under the new procedural scheme, the ALJs make formal findings of fact and draw conclusions of law.14 The Board, acting as a “quasi-judicial” internal appellate review mechanism,15 then considers the record developed before the ALJs and determines if their decisions are supported by substantial evidence and are in accordance with law.16 33 U.S.C. § 921(b)(3) (1976); see 20 C.F.R. § 802.301 (1982). The Board thus performs a review function identical to that which the District Courts performed prior to the 1972 amendments.17 The claims decisions, once considered by the Board, can be reviewed again by the Courts of Appeals, on petition, to determine if they are supported by substantial evidence and if they are in accordance with law.18 33 U.S.C. § 921(c) (1976). See Nat’I Steel & [141]*141Shipbuilding Co. v. Bonner, 600 F.2d 1288, 1292 (9th Cir.1979); Presley v. Tinsley Maintenance Serv., 529 F.2d 433, 436 (5th Cir.1976). Thus the Board screens cases, administers Department policy, and apparently reduces the number of cases that will be taken to the Courts of Appeals; its review function, a replacement for the District Court’s review, is duplicated in those cases that actually do advance to the Courts of Appeals.19
The Board’s members are appointed by the Secretary under the specific mandate of the Act. 33 U.S.C. § 921(b)(1) (1976).20 Julius Miller was appointed to the Board in 1974, and Ismene Kalaris was appointed in 1978. They served on the Board until April 30,1982, when the Under Secretary of Labor informed them that they were to be removed from their positions on the Board, effective May 31,1982. No reasons were given for the removals.21 No member of the Board had ever previously been involuntarily removed from office.22
In May 1982 Miller and Kalaris brought these actions for declaratory and injunctive relief.23 They argued that the Board was an Article III court and that they, as judges on an Article III court, were entitled to life tenure and could not be removed during good behavior. Alternatively the complaint asserted that Congress intended in the Act to create a Board which was independent of the Secretary and whose members could therefore not be removed absent a showing of “cause.”
The District Court rejected the removed members’ claim that the Board was an Article III court and that they were thus entitled to life tenure. JA 144-145. But to avoid casting the constitutionality of the statute into doubt, it accepted the Board members’ argument that Congress, despite its silence, meant to require the Secretary to show “cause” before removing a member from this “independent and quasi-judicial” tribunal. JA 143-144. The District Court concluded that 33 U.S.C. § 921(b) (1976), the provision authorizing the Secretary to appoint Board members, would be unconstitutional if it were construed to permit the Secretary “to influence claims decisions * * through replacement of the entire Board.” JA 142. Citing numerous admonishments in two Supreme Court decisions, Humphrey’s Executor v. United States, 295 U.S. 602, 55 S.Ct. 869, 79 L.Ed. 1611 (1935), and Wiener v. United States, 357 U.S. 349, 78 S.Ct. 1275, 2 L.Ed.2d 1377 (1958),24 the Dis[142]*142trict Court found that the statute barred the Secretary from removing the Board members from their positions without showing cause and providing an opportunity for hearing.25 JA 145-146. Consequently, the District Court granted the removed members’ motion for summary judgment and enjoined their removal from the Board. The Secretary appeals this decision, and the removed members cross-appeal the District Court’s denial of the Board’s Article III status.
II. The Board’s Article III Status
Article III, Section 1 of the federal Constitution provides:
The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish. The Judges both of the supreme and inferior Courts, shall hold their Offices during good Behaviour, and shall, at stated Times, receive for their Services, a Compensation, which shall not be diminished during their Continuance in Office.
U.S. Const. Art. Ill, § 1. This section requires the Congress to provide certain protections—specifically, life tenure and guaranty against salary diminution—for all judges on Article III courts.26 The District Court held that the Board was not an Article III court, however, because Congress “expresses clearly which courts enjoy Article III status * * * [and] Congress has not done so here.” JA 144-145. The removed members argue that it is not the label that Congress uses that determines which adjudicative bodies are Article III courts, but rather the powers that Congress vests in them, and the powers that Congress vested in the Board, they contend, were those of' an Article III court.27
[143]*143The removed members are correct in pointing out that the District Court employed the wrong test for determining whether Congress has created an Article III court. While Justice Harlan did once suggest that the only way to tell an Article I court from an Article III court is to examine the “establishing legislation [to see if it] complies with the limitations of [Article HI]» 28—and this does come “dangerously close to saying that Article III courts are those with Article III judges,”29—all of the opinions filed in the Court’s latest Article III case, Northern Pipeline Const. Co. v. Marathon Pipe Line Co.,— U.S.—, 102 S.Ct. 2858, 73 L.Ed.2d 598, (1982)30 agree that it is not what Congress says but what powers Congress vests in the adjudicatory body that counts.31 What the Northern Pipeline plurality, concurring, and dissenting opinions could not agree upon were the circumstances in which Congress could constitutionally vest certain traditional attributes of the judicial function in adjudicatory bodies whose judges do not have the benefits of life tenure and the guarantee against salary diminution.32
[144]*144[II] The removed members argue that Congress’ amendments to the Act in 1972 endowed the Board with Article III powers and the Board’s members with Article III protections.33 They point to five separate indicia of the Board’s Article III status: (1) the Board adjudicates cases of “private rights”; (2) the Board exercises a judicial review function previously performed by the federal District Courts; (3) the Board applies the “substantial evidence” test when it reviews administrative law judge decisions; (4) the Board has jurisdiction over admiralty matters; and (5) the Board is free of agency oversight. Reply brief for appellees/cross-appellants at 3. But we do not think that these indicia—taken either alone or together—prove that Congress created an Article III court when it assigned the intermediate review of workers’ compensation claims to the Board.
First, there can be no doubt that adjudication of workers’ compensation claims involves “private rights.” The Supreme Court so characterized such claims when it approved the constitutionality of the Act’s original scheme, in which deputy commissioners, the subordinates of other Executive officials, rendered the initial determinations. See Crowell v. Benson, 285 U.S. 22, 52 S.Ct. 285, 76 L.Ed. 598 (1932). But the Court has never indicated that all federally created private rights must be adjudicated in Article III courts. Northern Pipeline effectively held that certain private state law claims, when adjudicated within the federal system, must be decided by Article III courts.34 Even the plurality opinion, which would have gone farther than the Court’s effective holding, approved the initial determination of “private rights” by non-Article III judges,35 so long as the “essential attributes of the judicial power” were reserved in Article III courts.36 Thus it is clear that Article III does not require Article III judges to perform every stage of adjudication where “private rights” are at stake.
Second, though the Board exercises a review function previously performed by the District Courts, this review function could also have been performed by a non-Article III court under the 1932 version of the- Act. Under that version, the District Courts reviewed findings of fact to determine if they were supported by substantial evidence and legal conclusions to see if they [145]*145were in accordance with law.37 Because courts could fully review the deputy commissioners’ legal conclusions, delegating the initial determination did not “interfere with * * * the exercise by the court of its jurisdiction.” Crowell v. Benson, supra, 285 U.S. at 49-50, 52 S.Ct. at 291-292. Moreover, because courts reviewed the factual findings to determine if they were supported by substantial evidence, the legislation did not improperly deprive Article III courts of access to the necessary facts.38 This same scheme has been preserved in the 1972 version of the Act: the Courts of Appeals review legal decisions to determine if they are in accordance with law and review findings of fact to determine if they are supported by substantial evidence.39 While the Board applies the same appellate standards, it is simply providing an additional level of review.40 Article III requires only that the ultimate “judicial power” be reserved in the Article III courts; it does not require that all adjudicative bodies exercising the review “standards” that Article III courts exercise be constituted as Article III courts.41 Thus the fact that the Board replaced the District Court in the new claims procedure scheme,42 where more than “traditional” appellate review was maintained in the appellate courts,43 does not make the Board an Article III court. For the same reasons, the fact that the Board conducts “substantial evidence” review does not so vest it with judicial powers that it must be considered an Article III court.44
[146]*146Third, though the Board’s jurisdiction includes admiralty cases, and such cases do arise “under * * * the Laws of the United States” within the meaning of Article III, Section 2, the Supreme Court has already decided that non-Article III adjuncts can be constitutionally employed in admiralty and maritime cases. Crowell v. Benson, supra. The law is emphatically clear that when Congress creates a substantive federal right, it possesses substantial discretion to prescribe the manner in which that right may be adjudicated—including assigning to an adjunct some functions historically performed by judges. Northern Pipeline, supra,— U.S. at —, 102 S.Ct. at 2875. This is what Congress has done with the Board.
Fourth, even if the removed members are correct in asserting that the Board is free from oversight and review of the Executive Branch,45 it does not follow that the Board is an Article III court and that Board members are Article III judges. Congress can rationally and constitutionally create an administrative framework in which the Executive has only a limited form of control over the administrative appellate process. The test of an Article III court is not how much control the Executive has over an adjudicatory body, but whether an adjudicatory body has enough characteristics of an Article III court. Freedom from oversight is a protection afforded to Article III courts; it is not a test of their existence.
Finally, not only do these indicia not make out an Article III court, many of the other, more “essential attributes of the judicial power” expressly were not vested in the Board. The Board does not have the power of the subpoena or the power to punish anyone for contempt.46 33 U.S.C. § 927 (1976). The Board possesses only limited powers to issue compensation orders and it must resort to an appropriate District Court to have its orders enforced.47 Id. §§ 921(b)(3), 921(d). The Board’s narrow jurisdictional grant extends only “to claims of employees [under the Act],” and not to all potentially related matters.48 Id. § 921(b)(3). It plays only a limited role in reviewing ALJ determinations and obviously does not exercise all of the jurisdiction usually conferred on District Courts.49 [147]*147Moreover, the Board does not have to follow the rules of evidence, id. § 923, which “govern proceedings in courts of the United States * * Fed.R.Evid. 101.
In sum, the removed members have not shown that the 1972 amendments created an Article III court within the Department of Labor. To the contrary, so many of the essential attributes of an Article III court were omitted that we must conclude that Congress intended to and did create an administrative appellate review board. Congress has the power to place this Board’s limited function anywhere it chooses: in a federal court, in an independent agency, or in an Executive agency. See generally L. Jaffe, Judicial Control of Administrative Action 87-94 (1965). The removed members have not shown that Congress chose the federal court route.50 We therefore affirm the District Court on this issue.
III. The Board Members’ Non-Article III Status
The removed members failed to prevail on their Article III claim in the District Court. But they also claimed that Congress intended that the Secretary could only remove them for “cause.” Though the statute was silent concerning removal,51 the District Court concluded that Congress must have intended to so limit him because of the quasi-judicial duties it assigned to the Board. JA 144. Therefore, the District Court granted the removed members injunctive and declaratory relief on this issue. We find that the District Court was in error.
A. The Rule of Statutory Silence
The general and long-standing rule is that, in the face of statutory silence, the power of removal presumptively is incident to the power of appointment. In re Hennen, 38 U.S. (13 Pet.) 230, 10 L.Ed. 225 (1839); Cafeteria & Restaurant Wkrs Union, Local 473 v. McElroy, 367 U.S. 886, 81 S.Ct. 1743, 6 L.Ed.2d 1230 (1961). The Supreme Court has noted that “government employment, in the absence of legislation, can be revoked at the will of the appointing officer.”52 Id. at 896, 81 S.Ct. at 1749. And this circuit has recently noted that “this continues to be the rule to the present day.” Nat’l Treasury Employees Union v. Reagan, 663 F.2d 239, 247 (D.C.Cir.1981) (no nonstatutory protection for federal appointees).53 Thus the long-standing rule would hold Board members to indefinite terms at their appointing officer’s—the Secretary’s —discretion.54
[148]*1481. The sounds of silence.
The 1972 amendments to the Act did not specify the length or terms of Board members’ service. But there are suggestions in the history of the Act and its subsequent administration that Congress affirmatively intended for Board members, as part of the Department of Labor’s staff, to serve as other appointed officials serve—at the discretion of the Secretary.
For one thing, in enacting the 1972 amendments Congress plainly considered a report which recommended that, inter alia, members of workers’ compensation appeals boards like the Benefits Review Board be appointed for fixed terms with protection against removal.55 Congress gave “most careful consideration” to this report, see H.R.Rep. No. 92-1441, 92d Cong., 2d Sess. 4 (1972), but did not adopt the fixed term proposal.56 Instead, Congress placed the Board “within the Department of Labor” and instructed the Secretary “to keep separate the functions of administering the program and sitting in judgment on the hearings.”57 S.Rep. No. 92-1125, 92d Cong., 2d Sess. 13-15 (1972). Congress gave the Secretary the responsibility of setting “the machinery [of the Board] in motion,” Continental Air Lines, Inc. v. CAB, 519 F.2d 944, 954-955 (D.C.Cir.1975), cert. denied sub nom. Western Airlines, Inc. v. Continental Air Lines, Inc., 424 U.S. 958, 96 S.Ct. 1436, 47 L.Ed.2d 365 (1976) (quoting Power Reactor Development Co. v. Int’l Union of Elec., Radio & Mach. Wkrs, 367 U.S. 396, 81 S.Ct. 1529, 6 L.Ed.2d 924 (1961)), and of determining the appropriate manner in which claims should be adjudicated and the Act administered.58 See 33 U.S.C. § 939 (1976) (Secretary charged with duty of issuing regulations to implement the statute).
The Secretary immediately implemented Congress’ instructions. In his initial organizational order the Secretary placed the Board within the Office of the Under Secretary of Labor rather than in the Office of the Assistant Secretary. 20 C.F.R. §§ 801.-104, 801.302 (1982).59 The order explained;
[149]*149[Placing the Board within the Office of the Under Secretary] was deemed necessary because the Board’s functions are quasi-judicial in character and involve review of decisions made in the course of the administration of the several Acts by the Employment Standards Administration which is headed by an Assistant Secretary. * * *
38 Fed.Reg. 6171 (March 7, 1973). The Secretary, consistent with Congress’ intent, see S.Rep. No. 92-1125, supra, at 13-15, was attempting to insulate the Board from those who would be subject to its review— namely, the Employment Standards Administration, which the Assistant Secretary heads.60 But the Secretary was not trying to, and did not have to, create an impregnable fortress of protection for the Board.
Thus, pursuant to his statutory authority to issue regulations governing establishment and operation of the Board, 33 U.S.C. § 939 (1976), he promulgated 20 C.F.R. § 801.201(d) (1982), providing that:
All members of the Board shall serve indefinite terms to be determined in the discretion of the Secretary.
This regulation gave the Secretary some control over the Board, a control that Congress might have deemed necessary since the Secretary was to be held accountable for agency operations. The regulation was implemented in 1973 and has been in effect, without interruption,61 since that time. Thus, from the inception of the 1972 amendments, those charged with administering the statute have consistently construed it as giving the Secretary the traditional power of removal.62 In the sounds of silence, courts are “duty bound to follow ‘the construction of a statute by those charged with its execution ... unless there are compelling indications that it is wrong.’ ” Haviland v. Butz, 543 F.2d 169, 174 (D.C.Cir.), cert. denied, 429 U.S. 832, 97 S.Ct. 95, 50 L.Ed.2d 97 (1976) (quoting Red Lion Broadcasting Co. v. FCC, 395 U.S. 367, 381, 89 S.Ct. 1794, 1801, 23 L.Ed.2d 371 (1969)), especially when that construction occurs contemporaneously with enactment of the statute.63 We cannot find “compelling indications” that this regulation contravenes the congressional intent in the face of such history. Thus we must defer to the Secretary’s interpretation as a sound expression of congressional will.64
[150]*150The Secretary’s interpretation of the original congressional intent is further supported by recent floor activity in Congress.65 In 1981 Senator Don Nickles, chairman of the Subcommittee on Labor of the Senate Committee on Labor and Human Resources, introduced legislation to make the Board more independent of the administrative arm of the Department of Labor.66 Senator Nickles explained:
The 1972 amendments also created a two-step administrative appeal process within the Department of Labor, including a Benefit Review Board whose three members are appointed by the Secretary of Labor and serve at his pleasure.
127 Cong.Rec. S5077 (daily ed. May 14, 1981) (emphasis added). Senator Nickles believed that the Board needed a major facelift for it to have the proper degree of independence. He believed that S. 1182 would improve the administration of the Act
by establishing the Benefits Review Board and administrative law judges as a tribunal independent of the Department of Labor. The members of the Board are to be appointed by the President for fixed terms with the advice and consent of the Senate. The Secretary of Labor and his designees will not participate in litigation before the Board. * * *
Id. at S5078. Thus, not only did Senator Nickles want to prevent the Secretary from removing Board members, he also wanted to elevate Board members to the status of [151]*151officers of the United States (as opposed to inferior officers) and leave their appointment to the President.
The proposed bill was the subject of intensive debate in the legislative hearings, especially concerning the status of the Board. See Hearings on Longshoremen’s and Harbor Workers’ Compensation Act Amendments of 1981 Before the Subcommittee on Labor of the Committee on Labor and Human Resources of the United States Senate, 97th Cong., 1st Sess. (1981) (1981 Hearings). Then-chairman of the Board, Samuel Smith, testified that:
The Board performs the same judicial function which the U.S. District Courts exercised prior to 1972. The term of office is indefinite with no procedures for removal. * * *
* * * An important change proposed in S. 1181 is the removal of the Board from the Department of Labor and its establishment as an independent agency. * *
1981 Hearings at 217, 219 (statement of Chairman Samuel Smith). Some other witnesses argued that the Board should be removed from the Department of Labor and made independent of the Secretary,67 while other witnesses argued that the Board should remain accountable to the Secretary.68 But no one argued that the Board was already independent of the Secretary; the debate centered on whether change was desirable.69 Thus it would appear that the current Congress might view the independence of Board members as a change from their present status. These are sounds of congressional silence that reinforce the Secretary’s present claim of authority to remove Board members at his discretion.
2. Quasi-judicial functions.
Despite the Secretary’s presumptive right to remove his appointees at his discretion and the administrative and congressional history affirming this presumption, the removed members argue that Congress could not have intended to grant the Secretary this influence and control over officials who perform this “quasi-judicial” function of adjudicating “private rights.”70 Rather, to [152]*152preserve the unbiased, independent judgments of these officials, the removed members claim that Congress must have intended that the Secretary, at a minimum, show “cause” to remove them. The District Court agreed with them, finding that the general rule of silence has no application to officials who perform a “quasi-judicial” function. The District Court drew upon the Supreme Court’s decisions in Humphrey’s Executor v. United States, supra, and Wiener v. United States, supra, in constructing this interpretation of the 1972 congressional intent. JA 143-144.
Humphrey’s Executor involved President Roosevelt’s attempt to remove a member of the Federal Trade Commission (FTC)—an independent regulatory agency that Congress created to perform “quasi-legislative” and “quasi-judicial” tasks71—without cause72 Congress established the FTC as a body independent of the Executive Branch, prescribed fixed terms for its commissioners, and stipulated the exclusive terms for their removal to be “inefficiency, neglect of duty, or malfeasance in office.” 295 U.S. at 620, 55 S.Ct. at 870. In rejecting President Roosevelt’s claim to discretionary removal power over FTC commissioners, the Supreme Court stated:
The authority of Congress, in creating quasi-legislative or quasi-judicial agencies, to require them to act in discharge of their duties independently of executive control cannot be well doubted; and that authority includes, as an appropriate incident, power to fix the period during which they shall continue in office, and to forbid their removal except for cause in the meantime. For it is quite evident that one who holds his office only during the pleasure of another, cannot be depended upon to maintain an attitude of independence against the latter’s will.
Id. at 629, 55 S.Ct. at 874. Thus Humphrey’s Executor trimmed back considerably on the broad, constitutionally-based removal powers the President had hitherto enjoyed.73
Wiener presented the Supreme Court with a very similar presidential effort to exercise broad removal powers. In Wiener the Court ruled that President Eisenhower could not remove members of the War Claims Commission (WCC)—the body responsible for making final determinations regarding awards to those suffering injury or property damage at the hands of the enemy during World War II—at his discretion.74 Congress placed the WCC outside the Executive Branch, gave the Commission itself (and thus its members) a limited term of three years, and stipulated that the Commission’s decisions were not “subject to review by any other official of the United States or by any other court by mandamus or otherwise * * *.” 357 U.S. at 354-355, 78 S.Ct. at 1278-1279.- But nothing was explicitly said in the Act about removal. So the Court noted that it was faced with “another instance in which the most appropriate legal significance must be drawn from congressional failure of explicitness. Necessarily this is a problem in probabilities.” Id. at 352-353, 78 S.Ct. at 1277-1278. Based on all the limits Congress placed on Executive power in the Act, the Court concluded that Congress did not intend to allow the President to remove WCC commissioners at his discretion. Id. at 354-356, 78 S.Ct. at 1278-1279.
[153]*153But Humphrey’s Executor’s FTC and Wiener’s WCC were structurally very different from the Board, and it was these structural differences that prompted the Court to limit the Executive’s removal power. To begin with, both FTC and WCC members had fixed terms, FTC members’ terms being fixed by statute and WCC members’ terms being fixed by the limited life of the Commission. Humphrey’s Executor, which was the foundation of the Wiener decision, see 357 U.S. at 352, 354, 356, 78 S.Ct. at 1277, 1278, 1280, went to great lengths to limit its holding to cases where Congress had defined fixed terms for agency members.75 295 U.S. at 622, 631-632, 55 S.Ct. at 871, 875. Humphrey’s Executor stated that the facts before it were “plainly and wholly different” from the facts in cases such as Shurtleff v. United States, 189 U.S. 311, 23 S.Ct. 535, 47 L.Ed. 828 (1903), which held that officers whose terms are not fixed by statute serve at the pleasure of the officers who appoint them.76 Id. at 621-623, 55 S.Ct. at 871- ' 872.77 Second, both the FTC and the WCC were placed outside the Executive Branch, as separate, independent tribunals.78 The Board, by contrast, was placed “within the Department of Labor,”79 as an “internal” administrative appellate review board,80 and it relies very much on the Department for its effective day-to-day operations.81 Third, the Executives removing both FTC and WCC commissioners did not rely on previously promulgated regulations interpreting the congressional silence; rather, they acted in contravention of explicit con[154]*154gressionally-mandated terms of office. By contrast, here the Secretary relies on his own regulation promulgated a decade ago. Such a regulation deserves the deference of this court, absent compelling indications that it is wrong. See note 64 supra. Fourth, and finally, both the FTC and the WCC members were made officers of the United States, appointed by the President with the advice and consent of the Senate. 295 U.S. at 620, 55 S.Ct. at 870; 357 U.S. at 350, 78 S.Ct. at 1276. Board members, by contrast, are inferior officers of the United States, appointed by the Secretary of Labor. Had Congress wished to give Board members something more than the “lesser dignity” of officials appointed and removable at the discretion of the respective heads of their departments, it could have said so explicitly.82 But it chose to remain silent.
In short, Humphrey’s Executor and Wiener involved structurally distinguishable entities and do not serve as appropriate support for the removed members’ claim. Indeed, the Supreme Court’s decisions in Reagan v. United States, 182 U.S. 419, 21 S.Ct. 842, 45 L.Ed. 1162 (1901), and In re Hennen, 38 U.S. (13 Pet.) 230, 10 L.Ed. 225 (1839), are more clearly on point and control this case. In Reagan the Court held that the commissioners of Indian Territory, inferior officers who performed entirely judicial functions—like justices of the peace—were removable at will in the absence of a congressionally fixed term.83 182 U.S. at 426-427, 21 S.Ct. at 845. In Hennen the Court found that a District Court judge could remove, at his discretion, a clerk of the court since no tenure in office was specified in either the Constitution or the statute.84 38 U.S. (13 Pet.) at 259. The Hennen Court stated;
All offices, the tenure of which is not fixed by the Constitution or limited by law, must be held either during good behaviour, or (which is the same thing in contemplation of law) during the life of the incumbent; or must be held at the will and discretion of some department of the government, and subject to removal at pleasure.
It cannot, for a moment, be admitted, that it was the intention of the Constitution, that those offices which are denominated inferior offices should be held during life. And if removable at pleasure, by whom is such removal to be made[?] In the absence of all constitutional provision, or statutory regulation, it would seem to be a sound and necessary rule, to consider the power of removal as incident to the power of appointment. * * *
Id. See also DeCastro v. Board of Comm’rs of San Juan, 322 U.S. 451, 462, 64 S.Ct. 1121, 1127, 88 L.Ed. 1384 (1944) (interpreting a statute so that implying life tenure for a large group of “municipal employees [would be] in disregard of the rule of Shurt[155]*155leff v. United States”); Nat’l Treasury Employees Union v. Reagan, 663 F.2d 239, 246-248 (D.C.Cir.1981) (relying on Hennen). These cases conclusively demonstrate that, in the absence of a congressional statement to the contrary, inferior officers such as those on the Board serve indefinite terms at the discretion of their appointing officers.85
B. Constitutionality of the Organizational Scheme
We thus hold that Congress intended to create a Board whose members serve indefinite terms at the discretion of their appointing officer.86 The Secretary can therefore remove these members at his discretion unless there is some constitutional impediment to his doing so.87 The District Court found that it would be unconstitutional for the Secretary to have a power of removal over Board members because such a power would “permit him to influence claims decisions outside the adjudicatory process through replacement of the entire Board.” JA 142. But it avoided bringing the constitutionality of the organizational scheme into question by finding that Congress intended to make the Board independent of the Secretary.88 Since we find that Congress intended Board members to serve at the Secretary’s discretion, we must judge the constitutionality of the organizational scheme.89 We find that assignment [156]*156of initial review of adjudication of workers’ compensation claims to an administrative review board whose members serve at the discretion of their appointing officer is clearly constitutional.
Under our constitutional scheme, tenure in office is during good behavior, for statutorily fixed periods and stipulated terms, or at the discretion of the appointing officer. In re Hennen, supra; Nat’l Treasury Employees Union v. Reagan, supra. The Constitution mandates that members of Article III courts have life tenure during good behavior. The Constitution permits Congress to establish fixed terms for members of tribunals that are independent of the Executive Branch; when Congress statutorily specifies the terms of tenure and removal for United States officials it does not infringe upon the autonomy of the Executive Branch. But where Congress has neither created an Article III court nor established by legislation the terms for tenure and removal, the Constitution leaves the tenure of these officers to the discretion of the appointing officer. Cafeteria & Restaurant Wkrs Union, Local 473 v. McElroy, supra; Myers v. United States, supra; Reagan v. United States, supra. Properly understood, these tenure rules are part of the careful balance of structural separation of powers limitations and protections that the Constitution places on Congress, the Executive, and the courts.
The District Court found, and we agree, that the Board is not an Article III court and therefore that the Constitution does not require that its members serve during good behavior. JA 144-145. But the District Court, invoking separation of powers principles, concluded that Board members could not constitutionally be removed at will; it found that the Constitution requires Congress to create “quasi-judicial” bodies that are independent of the appointing officer. JA 144. Quoting from Humphrey’s Executor, supra, 295 U.S. at 629-630, 55 S.Ct. at 874, the District Court explained:
The fundamental necessity of maintaining each of the three general departments of government entirely free from the control or coercive influence, direct or indirect, of either of the others, has often been stressed and is hardly open to serious question. So much is implied in the very fact of the separation of the powers of these departments by the Constitution; and in the rule which recognizes their essential co-equality. * * *
JA 142. It found support for its application of separation of powers principles in both Humphrey’s Executor and Wiener.90
[157]*157But the District Court misinterpreted the Supreme Court’s discussion of separation of powers principles in both Humphrey’s Executor and Wiener. Humphrey’s Executor did not hold that Congress was required to make FTC commissioners independent of the President; rather, it decided that separation of powers limitations and protections allowed Congress to supplant the President’s traditional removal authority. Similarly, Wiener did not hold that Congress was required to make WCC commissioners independent of the President; rather, it decided that separation of powers limitations and protections allowed Congress to do so. In each case the Court looked to the function the administrative body was to perform to determine if Congress was infringing upon the Executive’s constitutional power, not to see if the Executive was infringing upon the administrative agency’s adjudicative function.91 See note 75 supra.
Indeed, the Supreme Court has already decided that Congress can constitutionally confer on an administrative adjunct jurisdiction to decide the liability of an employer to an employee under the Act. Crowell v. Benson, supra, 285 U.S. 22, 52 S.Ct. 285, 76 L.Ed. 598.92 Crowell held that Congress could constitutionally assign the initial determination of workers’ compensation claims to deputy commissioners, the subordinates of the Act’s Executive officers. Id. at 51, 54, 52 S.Ct. at 292, 293.. Crowell determined that this scheme satisfied the constitutional mandate of separation of powers embodied in Article III93 and did not improperly withdraw necessary questions from judicial consideration or “interfere with * * * the exercise by the court of its jurisdiction * * Id. at 49-50, 52 S.Ct. at 291-292.
Of course, the Act as presently codified differs from the Crowell version. ALJs now perform the initial adjunct adjudicatory function that the deputy commissioners performed before the 1972 amendments.94 And the Board now performs the initial appellate review that the District Courts used to perform.95 But the “essential attributes of the judicial power” remain in the Article III courts, and the Board is simply an additional layer of administrative [158]*158review.96 Thus, for constitutional purposes, the organizational scheme created in the 1972 amendments does not differ from the Crowell version. Crowell, therefore, is dis-positive of this case.
The removed members are certainly correct in characterizing the Board as performing a “quasi-judicial” function.97 But this general characterization does little to distinguish the Board, constitutionally, from the scores of administrative boards and tribunals in the Executive Branch that currently adjudicate claims to federal statutory rights. See generally S. Breyer & R. Stewart, Administrative Law and Regulatory Policy 37-102 (1979). Many statutes directly grant the Executive power to remove officials performing quasi-judicial tasks.98 Other statutes grant broad delegatory powers pursuant to which heads of agencies have required members of “quasi-judicial” boards to serve at their discretion.99 And many other statutes authorize agency heads to influence or control indirectly the adjudications of their “quasi-judicial” boards.100 The removed members have not shown how these other tribunals and boards differ, either structurally or functionally, in a constitutionally significant sense.101 Nor have they indicated why [159]*159the additional degree of independence and protection they seek is essential for dispassionate decisionmaking under this statute, and not others, for constitutional purposes.102 Congress has been creating quasi-judicial boards subject to Executive control for years,103 and the courts have not previously prevented them from doing so. To do so now “would be to turn the clock back on at least a * * * century of administrative law,” Sunshine Anthracite Coal Co. v. Adkins, 310 U.S. 381, 400, 60 S.Ct. 907, 915, 84 L.Ed. 1263 (1940) (rejecting challenge to quasi-judicial authority delegated to the Department of the Interior in the Bituminous Coal Conservation Act of 1935), and would unnecessarily call into constitutional question the validity of the many quasi-judicial boards whose judgments are subject to the direct or indirect control of the Executive Branch. We refuse to do either.
IV. Conclusion
The long-standing rule relating to the removal power is that, in the face of congressional silence, the power of removal is incident to the power of appointment. We can find nothing in Article III or this Act which interdicts this long-standing rule. All of the available evidence indicates that Congress intended to allow the Secretary to remove these Board members in his discretion, and nothing in Article III, separation of powers principles, or the decisions of the Supreme Court prevents Congress from doing so. Thus the judgment of the District Court is
Affirmed in part104 and reversed in part.105
