TAMM, Circuit Judge:
Plaintiffs, appellees here, brought an action in the United States District Court for the District of Columbia to prohibit Michael Pertschuk, Chairman of the Federal Trade Commission (Commission), from participating in a pending rulemaking proceeding concerning children’s advertising. The district court, citing this court’s decision in Cinderella Career & Finishing Schools, Inc. v. FTC, 138 U.S.App.D.C. 152, 425 F.2d 583 (D.C.Cir.1970), found that Chairman Pertschuk had prejudged issues involved in the rulemaking and ordered him disqualified. We hold that the Cinderella standard is not applicable to the Commission’s rulemaking proceeding. An agency member may be disqualified from such a proceeding only when there is a clear and convincing showing that he has an unalterably closed mind on matters critical to the disposition of the rulemaking. Because we find that the appellees have failed to demonstrate the requisite prejudgment, the order of the district court is reversed.
I
On April 27, 1978, the Commission issued a Notice of Proposed Rulemaking that suggested restrictions regarding television advertising directed toward children.1 The decision to commence rulemaking under section 18 of the Federal Trade Commission (FTC) Act2 was accompanied by a state[1155]*1155ment setting forth “with particularity the reason for the proposed rule.” 3 The Commission explained that it had decided to propose a rule limiting children’s advertising after consideration of a staff report that discussed
facts which suggest that the televised advertising of any product directed to young children who are too young to understand the selling purpose of, or otherwise comprehend or evaluate, commercials may be unfair and deceptive within the meaning of Section 5 of the Federal Trade Commission Act, requiring appropriate remedy. The Report also discloses facts which suggest that the current televised advertising of sugared products directed to older children may be unfair and deceptive, again requiring appropriate remedy.
43 Fed.Reg. 17,967, 17,969 (1978) (footnotes omitted).4 The Commission invited interested persons to comment upon any issue raised by the staff proposal.5
On May 8, 1978, the Association of National Advertisers, Inc. (ANA), the American Association of Advertising Agencies (AAAA), the American Advertising Federation (AAF), and the Toy Manufacturers of America, Inc. (TMA) petitioned Chairman Pertschuk to recuse himself from participation in the children’s advertising inquiry. The petition charged that Pertschuk had made public statements concerning regulation of children’s advertising that demonstrated prejudgment of specific factual issues sufficient to preclude his ability to serve as an impartial arbiter. See Appendix (A.) at 11, 15. The charges were based on a speech Pertschuk delivered to the Action for Children’s Television (ACT) Research Conference in November 1977, on several newspaper and magazine articles quoting Chairman Pertschuk’s views on children’s television, on the transcript of a televised interview, and on a press release issued by the Commission during the summer of 1977.6
On July 13, 1978, Chairman Pertschuk declined to recuse himself from the proceeding. Pertschuk stated his belief that the disqualification standard appropriate for administrative adjudications did not apply to administrative rulemaking, id. at 57-58, and that, even if adjudicative criteria were relevant, his remarks did not warrant disqualification because they did not concern the petitioners in particular; rather, they addressed the “issue of advertising to children and the policy questions raised by it,” id. at 64 (emphasis in original). Five days later, the Commission, without Pertschuk participating, also determined that Pertschuk need not be disqualified. Id. at 65.
In August 1978, ANA, AAAA, AAF, and TMA petitioned the district court to declare that Chairman Pertschuk should be disqualified from participating in the children’s television proceeding. ANA, AAAA, AAF, and TMA also sought preliminary and permanent injunctions barring Pertschuk’s participation and an order requiring the remaining Commissioners to reconsider all matters previously decided in the inquiry. The plaintiffs introduced copies of three letters, sent by Chairman Pertschuk on the day after he delivered the ACT speech, as additional evidence of his alleged prejudgment. The letters accompanied a copy of the speech.
On September 8, 1978, the Kellogg Company (Kellogg), a food manufacturer that [1156]*1156advertises on television programs regularly viewed by children, moved to intervene as a plaintiff. The district court granted the motion on October 4,1978. Two days later, Kellogg introduced as evidence in support of the motion for a preliminary injunction a copy of a letter sent by Chairman Pertschuk on November 17, 1977, to Donald Kennedy, Commissioner of the Food and Drug Administration.
On November 3, 1978, the district court ruled on cross-motions for summary judgment. The court, relying on Cinderella, found that Chairman Pertschuk “has prejudged and has given the appearance of having prejudged issues of fact involved in a fair determination of the Children’s Advertising rulemaking proceeding.” Accordingly, the .court granted the plaintiffs’ motion for summary judgment and ordered Pertschuk enjoined from further participation. Id. at 110. This appeal followed.7
II
Before we consider the merits of the district court’s decision, we pause at a procedural way station. The Commission asserts that the district court erred in considering the disqualification issue before the rulemaking proceeding had ended. As a general matter, of course, the exhaustion doctrine provides that challenges to agency action should not be heard until relevant administrative proceedings have been concluded. McKart v. United States, 395 U.S. 185, 194-95, 89 S.Ct. 1657, 23 L.Ed.2d 194 (1969). This permits an administrative agency to develop a factual record, to apply its expertise to that record, and to avoid piecemeal appeals. Id. at 193-94, 89 S.Ct. 1657.
Application of the exhaustion doctrine, however, is not inflexible. In rare circumstances, this court has considered extraordinary prejudgment claims prior to final agency action. See Amos Treat & Co. v. SEC, 113 U.S.App.D.C. 100, 306 F.2d 260 (D.C.Cir.1962). See also Fitzgerald v. Hampton, 152 U.S.App.D.C. 1, 14, 467 F.2d 755, 768 (D.C.Cir.1972); Sterling Drug, Inc. v. FTC, 146 U.S.App.D.C. 237, 249-250, 450 F.2d 698, 710-11 (D.C.Cir.1971). The district court agreed to consider the present case prior to exhaustion of the administrative process on the basis of these decisions.
The exception to the exhaustion doctrine upon which the district court relied is extremely narrow. In SEC v. R. A. Holman & Co., 116 U.S.App.D.C. 279, 281-282, 323 F.2d 284, 286-87 (D.C.Cir.1963), for example, this court refused to review a disqualification contention when a commissioner whose impartiality was challenged denied that he had participated in earlier administrative proceedings. This court noted that resolution of the disqualification issue would necessitate prolonged evidentiary hearings and, therefore, we concluded that review of the due process claim should follow final agency action. Similarly, in Associated Press v. FCC, 145 U.S.App.D.C. 172, 183-184, 448 F.2d 1095, 1106-07 (D.C.Cir.1971), this court refused to review, prior to final administrative action, an insubstantial disqualification claim that involved conflicting factual contentions.
Although the doctrine that permits review of a disqualification claim prior to final agency action is restrictive, the present case falls within its bounds. As the Supreme Court has emphasized, application of the exhaustion doctrine “requires an understanding of its purposes and of the particular administrative scheme involved.” McKart v. United States, 395 U.S. at 193, 89 S.Ct. at 1662. For the following reasons, we find that immediate review of the prejudgment claim will not thwart the purposes of exhaustion.
First, the challenge to Chairman Pertschuk’s further participation involves no disputed factual issues that demand the creation of a better administrative record. The agency has had an adequate opportunity to explain why Chairman Pertschuk need [1157]*1157not be recused.8 Second, the issue involved in this case — the prejudgment standard required by due process for section 18 rule-making — is a pure question of law. The Commission can bring no particular expertise to bear on its determination. Consideration of this question of first impression will not necessarily permit future piecemeal attacks on administrative processes.9 Under the particular circumstances of this case, we therefore conclude that the appellees’ claim may be heard.
Judge Leventhal, in his concurring opinion, voices some concern over the jurisdiction of the district court to entertain this action. In their complaints, however, the plaintiffs alleged a violation of their procedural rights under the Constitution and the Administrative Procedure Act (APA), 5 U.S.C. §§ 551-706 (1976). Thus, the district court clearly had jurisdiction — i. e., power— to resolve the controversy under 28 U.S.C. § 1331(a) (1976) (cases arising under the Constitution and the laws of the United States) and 28 U.S.C. § 1337 (1976) (cases arising under statutes regulating commerce). See generally Califano v. Sanders, 430 U.S. 99, 105, 97 S.Ct. 980, 51 L.Ed.2d 192 (1977). Once a plaintiff has alleged a nonfrivolous constitutional claim, the district court has jurisdiction under section 1331, and dismissal for want of jurisdiction is improper even if dismissal for failure to state a claim upon which relief could be granted would be proper. Bell v. Hood, 327 U.S. 678, 682-83, 66 S.Ct. 773, 90 L.Ed. 939 (1946). See 1 Moore’s Federal Practice ¶ 0.62[2.-2], at 664-65 (1977). Similarly, jurisprudential concerns, such as those embodied in the exhaustion doctrine, do not bear on whether a court has jurisdiction but only on whether it should exercise that jurisdiction.
This conclusion finds support in this court’s opinion in Wolf Corp. v. SEC, 115 U.S.App.D.C. 75, 317 F.2d 139 (D.C.Cir.1963) (Burger, J.). The plaintiff in that case had asked the district court to enjoin the Securities and Exchange Commission from holding a stop-order hearing. The district court dismissed the case not for want of jurisdiction but for failure to state a claim upon which relief could be granted. Id., at 77, 317 F.2d at 141. On appeal, this court affirmed because it believed the plaintiff should have exhausted its remedies before the agency first. In the process, the court stated expressly that the plaintiff’s allegation of a due process violation was sufficient to invoke the district court’s jurisdiction under 28 U.S.C. § 1337. It then agreed that dismissal for failure to state a valid claim, rather than for want of jurisdiction, was appropriate. Id. Moreover, like the case before us, Wolf arose under a proce[1158]*1158dural regime that provided for review of final agency decisions in the courts of appeals, not the district courts. Compare 15 U.S.C. § 77i (1976) (review of SEC orders), cited in Wolf Corp. v. SEC, 115 U.S.App.D.C. at 77 n.6, 317 F.2d at 141 n.6, with 15 U.S.C. § 57a(e)(1)(A) (1976) (review of FTC rules). Thus, where the final agency decision may be reviewed does not by itself determine the court in which a plaintiff seeking interlocutory relief may pursue his cause of action.
Ill
The Commission attacks the substance of the district court’s decision on two grounds. First, it insists that the standard for disqualification of an administrative decision-maker in rulemaking differs from the standard in adjudication. The Commission’s view rests on the different purposes of rule-making and adjudication and on the longstanding rule that due process requirements are not the same in the two contexts. Second, the Commission asserts that under any disqualification standard, Chairman Pertschuk cannot be found to have prejudged issues in contravention of due process.
The appellees respond with two contentions. First, they support the district court’s conclusion that Cinderella Career & Finishing Schools, Inc. v. FTC, 138 U.S.App.D.C. 152, 425 F.2d 583 (D.C.Cir.1970), applies to Commission rulemaking under section 18 of the FTC Act. Although Cinderella involved an adjudication, the appellees claim that the existence of procedures in section 18 rulemaking proceedings that are not required in informal notice-and-comment rulemaking under section 553 of the Administrative Procedure Act, 5 U.S.C. § 553 (1976),10 mandates application of the standard set out in that case. Second, they argue that Chairman Pertschuk’s statements indicate prejudgment sufficient to bar him from further participation in the children’s advertising proceeding.
We are, therefore, called upon to resolve two questions: (1) What is the appropriate standard by which to decide prejudgment in the context of a section 18 proceeding? (2) Has Chairman Pertschuk made statements that demonstrate prejudgment under that standard?
A
Before we examine either the structure of section 18 or the content of Pertschuk’s statements, we review our decision in Cinderella Career & Finishing Schools, Inc. v. FTC. In Cinderella, we held that the standard for disqualifying an administrator in an adjudicatory proceeding because of prejudgment is whether “ ‘a disinterested observer may conclude that [the decisionmaker] has in some measure adjudged the facts as well as the law of a particular case in advance of hearing it.’ ” 138 U.S.App.D.C. at 160, 425 F.2d at 591 (quoting Gilligan, Will & Co. v. SEC, 267 F.2d 461, 469 (2d Cir.), cert. denied, 361 U.S. 896, 80 S.Ct. 200, 4 L.Ed.2d 152 (1959)). See Texaco, Inc. v. FTC, 118 U.S.App.D.C. 366, 372, 336 F.2d 754, 760 (D.C.Cir.1964), vacated and remanded per curiam on other grounds, 381 U.S. 739, 85 S.Ct. 1798, 14 L.Ed.2d 714 (1965). See also Kennecott Copper Corp. v. FTC, 467 F.2d 67, 80 (10th Cir. 1972), cert. denied, 416 U.S. 909, 94 S.Ct. 1617, 40 L.Ed.2d 114 (1974). This standard guarantees that the adjudicative hearing of a person facing administrative prosecution for past behavior is before a decisionmaker who has not prejudged facts concerning the events under review.
The facts of the Cinderella case illustrate application of the standard. The Commission charged that Cinderella Career College and Finishing Schools, Inc. (Cinderella) made false representations in its advertising and engaged in deceptive practices in contravention of section 5 of the FTC Act, 15 U.S.C. § 45 (1976).11 For example, the [1159]*1159Commission alleged that Cinderella advertised “courses of instruction which qualify students to become airline stewardesses” and that its graduates were “qualified to assume executive positions.” 138 U.S.App.D.C. at 153 n.1, 425 F.2d at 584 n.1. An administrative law judge ruled that the Commission had failed to prove that the acts and practices violated the FTC Act, and he dismissed the complaint. Id. at 153 n.2, 425 F.2d at 584 n.2. Complaint counsel appealed the administrative law judge’s decision to the full Commission.
While the appeal was pending before the Commission, Chairman Paul Rand Dixon spoke at the Government Relations Workshop of the National Newspaper Association and stated:
What kind of vigor can a reputable newspaper exhibit? . . . What standards are maintained on advertising acceptance? . . . What about carrying ads that offer college educations in five weeks, ... or becoming an airline’s hostess by attending a charm school? . . . Granted that newspapers are not in the advertising policing business, their advertising managers are savvy enough to smell deception when the odor is strong enough.
Id., at 158-159, 425 F.2d at 589-90. Six months later, the Commission, with Chairman Dixon participating, found that Cinderella neither awarded nor was capable of awarding academic degrees, and that it offered no course of instruction that would qualify students as airline stewardesses. School Services, Inc., 74 F.T.C. 920, 1022, 1031, 1035 (1968). The Commission concluded that these and other representations were false and misleading in violation of section 5 of the FTC Act and ordered Cinderella to cease and desist from such practices. Id. at 1040-42.
On review, we found that Chairman Dixon’s remarks gave “the appearance that he ha[d] already prejudged the case and that the ultimate determination of the merits [would] move in predestined grooves.” 138 U.S.App.D.C. at 159, 425 F.2d at 590. Accordingly, we held that Chairman Dixon’s participation in the proceeding required reversal and remand of the Commission’s order.
B
The district court in the case now before us held that “the standard of conduct delineated in Cinderella" governs agency decisionmakers participating in a section 18 proceeding. A. at 107. Section 18 authorizes the Commission to promulgate rules designed to “define with specificity acts or practices which are unfair or deceptive.”12 Basically, it allows the Commission to enforce the broad command of section 5 of the FTC Act, which declares “unfair or deceptive acts or practices in or affecting commerce . . unlawful.”13 The district court ruled that a section 18 proceeding, notwithstanding the appellation rulemaking, “is neither wholly legislative nor wholly adjudicative.” According to the district court, the “adjudicative aspects” of the proceeding render Cinderella applicable. Id. at 106.
The appellees urge us to uphold the district court’s analysis of section 18. They emphasize two allegedly “adjudicatory aspects” of a section 18 proceeding: (1) interested persons are entitled to limited cross-examination of those who testify to disputed issues of material fact, see 15 U.S.C. § 57a(c)(1)(B) (1976), and (2) a reviewing court must set aside any rule not supported by substantial evidence in the rulemaking record taken as a whole, see 15 U.S.C. § 57a(e)(3)(A) (1976).14
[1160]*1160The district court’s characterization of section 18 rulemaking as a “hybrid” or quasi-adjudicative proceeding, A. at 106, ignores the clear scheme of the APA. Administrative action pursuant to the APA is either adjudication or rulemaking. The two processes differ fundamentally in purpose and focus:
The object of the rule making proceeding is the implementation or prescription of law or policy for the future, rather than the evaluation of a respondent’s past conduct. Typically, the issues relate not to the evidentiary facts, as to which the veracity and demeanor of witnesses would often be important, but rather to the policy-making conclusions to be drawn from the facts. . . . Conversely, adjudication is concerned with the determination of past and present rights and liabilities. Normally, there is involved a decision as to whether past conduct was unlawful, so that the proceeding is characterized by an accusatory flavor and may result in disciplinary action.
Attorney General’s Manual on the Administrative Procedure Act 14 (1947).15 See United States v. Florida East Coast Railway, 410 U.S. 224, 244-46, 93 S.Ct. 810, 35 L.Ed.2d 223 (1973).
Adjudication and rulemaking may be conducted pursuant to either informal or formal procedures.16 Informal rulemaking requires the administrative agency to provide “interested persons an opportunity to participate in the rule making through submission of written data, views, or arguments.” 5 U.S.C. § 553(c). Under section 706(2)(A), reviewing courts are required to uphold informal rulemaking decisions unless those decisions are “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” 5 U.S.C. § 706(2)(A) (1976).
Formal rulemaking is invoked when “rules are required by statute to be made on the record after opportunity for an agency hearing.” 5 U.S.C. § 553(c). Under sections 556 and 557 of the APA, 5 U.S.C. §§ 556-557 (1976), formal rulemaking must include a trial-type hearing at which a “party is entitled to present his case or defense or oral or documentary evidence, to submit rebuttal evidence, and to conduct such cross-examination as may be required for a full and true disclosure of the facts.” 5 U.S.C. § 556(d). Section 706(2)(E) governs judicial review of formal rulemaking and requires a court to set aside a rule that is “unsupported by substantial evidence.” 5 U.S.C. § 706(2)(E).
Formal adjudication is governed by section 554 of the APA and arises in “every case of adjudication required by statute to be determined on the record after opportunity for an agency hearing.” 5 U.S.C. § 554(a) (1976). Section 554 incorporates the procedural requirements of sections 556 and 557 and affords parties to a formal adjudication the right to present evidence and to conduct cross-examination. 5 U.S.C. § 554(c)-(d). Judicial review of formal adjudication, like that of formal rulemaking, [1161]*1161is governed by the substantial evidence standard.17
The foregoing descriptions merely outline the basic parameters of administrative action. Congress has, in the Magnuson-Moss Warranty — Federal Trade Commission Improvement (Magnuson-Moss) Act § 202(a), 15 U.S.C. § 57a (1976), and elsewhere,18 enacted specific statutory rulemaking provisions that require more procedures than those of section 553 but less than the full procedures required under sections 556 and 557.19 The presence of procedures not mandated by section 553, however, does not, as the appellees urge, convert rulemaking into quasi-adjudication. The appellees err by focusing on the details of administrative process rather than the nature of administrative action.
Our decision in Hercules, Inc. v. EPA, 194 U.SApp.D.C. 172, 598 F.2d 91 (D.C.Cir.1978), illustrates that the difference between rulemaking and adjudication is not affected by varying procedural practices. In that case, although we reviewed decisions of the Environmental Protection Agency under the substantial evidence standard, id., at 187, 598 F.2d at 106; see Environmental Defense Fund v. EPA (PCBs), 194 U.S.App.D.C. 143, 163-164, 598 F.2d 62, 82-83 (D.C.Cir.1978), we refused to find that the agency proceeding was adjudicatory. The Environmental Protection Agency was promulgating policy-based standards of general import and, thus, was engaged in rulemaking. Similarly, the Commission’s children’s advertising inquiry is designed to determine whether certain acts or practices will, in the future, be considered to contravene the FTC Act. The proceeding is not adjudication or quasi-adjudication. It is a clear exercise of the Commission’s rulemaking authority.
C
The appellees also argue that we must apply Cinderella because it involves a factual prejudgment similar to the one now before us. In Cinderella, Chairman Dixon made statements that reflected prejudgment that Cinderella Career & Finishing Schools, Inc. had engaged in certain acts. In this case, the appellees accuse Chairman Pertschuk of prejudging issues of material fact in the children’s television proceeding. We find that the appellees’ argument belies a misunderstanding of the factual basis of rules.
The factual predicate of a rulemaking decision substantially differs in nature and in use from the factual predicate of an adjudicatory decision. The factual predicate of adjudication depends on ascertainment of “facts concerning the immediate parties — who did what, where, when, how, and with what motive or intent.” 2 K. Davis, Administrative Law Treatise, § 15.-03, at 353 (1958). By contrast, the nature of legislative fact is ordinarily general, without reference to specific parties. Adjudicative and legislative facts are also used differently:
[AJdjudicative facts are those to which the law is applied in the process of adjudication. They are the facts that normally go to the jury in a jury case. . Legislative facts are the facts which help the tribunal determine the content of law [1162]*1162and of policy and help the tribunal to exercise its judgment or discretion in determining what course of action to take.
Id.20 Thus, legislative facts are crucial to the prediction of future events and to the evaluation of certain risks, both of which are inherent in administrative policymaking.
The case law demonstrates that the factual component of generalized rulemaking cannot be severed from the pure policy aspects of the rule.21 FCC v. National Citizens Committee for Broadcasting, 436 U.S. 775, 98 S.Ct. 2096, 56 L.Ed.2d 697 (1978), is illustrative. There, the Supreme Court reviewed the Federal Communication Commission’s decision to order prospective divestiture in cases of newspaper-television cross-ownership. The agency had based its decision on an assessment of the relevant market conditions. The Court, upholding the administrative action, stated that “complete factual support in the record for the [Federal Communication] Commission’s judgment or prediction is not possible or required; ‘a forecast of the direction in which future public interest lies necessarily involves deductions based on the expert knowledge of the agency.’ ” Id. at 814, 98 S.Ct. at 2122 (quoting FPC v. Transcontinental Gas Pipe Line Corp., 365 U.S. 1, 29, 81 S.Ct. 435, 5 L.Ed.2d 377 (1961)). See American Airlines, Inc. v. CAB, 123 U.S. App.D.C. 310, 359 F.2d 624 (D.C.Cir.1966) (en banc).22
Because legislative facts combine empirical observation with application of administrative expertise to reach generalized conclusions, they need not be developed through evidentiary hearings. See id., at 318-319, 359 F.2d at 632-33.23 To the contrary, however, “[w]here adjudicative, rather than legislative, facts are involved, the parties must be afforded a hearing to allow them an opportunity to meet and to present evidence.” Alaska Airlines, Inc. v. CAB, 178 U.S.App.D.C. 116, 122, 545 F.2d 194, 200 (D.C.Cir.1976) (footnote omitted). This dis[1163]*1163tinction has been established in judicial, as well as administrative, processes.24
Evidentiary hearings, although not necessary to determine legislative facts, nevertheless may be helpful in certain circumstances. For example, Congress, when it enacted the Magnuson-Moss Act, recognized that special circumstances might warrant the use of evidentiary proceedings in determining legislative facts. Under section 18(c)(1)(B)25 and section 18(c)(2)(B),26 the Commission must conduct a hearing, with a limited right of cross-examination, when it resolves disputed issues of material fact. The legislative history of the MagnusonMoss Act states that “[t]he only disputed issues of material fact to be determined for resolution by the Commission are those issues characterized as issues of specific fact in contrast to legislative fact.” H.R. Rep.No. 93-1606, 93d Cong., 2d Sess. 33 (1974) (Conference Report).
Although neither the Conference Report nor subsequent congressional debate amplify the term “specific fact,” its genesis can be traced to a recommendation of the Administrative Conference of the United States (ACUS).27 Prior to congressional action on the Magnuson-Moss Act, ACUS promulgated Recommendation No. 72-5, which suggested that Congress should not require [1164]*1164trial-type procedures “for making rules of general applicability, except that it may sometimes appropriately require such procedures for resolving issues of specific fact.” 1 C.F.R. § 305.72-5 (1974). In a letter dated July 27, 1973, then-ACUS Chairman Antonin Scalia answered Congressman Moss’s request for a definition of the term “specific fact”:
Conference Recommendation 72-5 is addressed exclusively to agency rulemaking of general applicability. In such a proceeding, almost by definition, adjudicative facts are not at issue, and the agency should ordinarily be free to, and ordinarily would, proceed by the route of written comments, supplemented, perhaps, by a legislative-type hearing. Yet there may arise occasionally in such rule-making proceedings factual issues which, though not adjudicative, nevertheless justify exploration in a trial-type format— because they are sufficiently narrow in focus and sufficiently material to the outcome of the proceeding to make it reasonable and useful for the agency to resort to trial-type procedure to resolve them. These are what the Recommendation refers to as issues of specific fact.28
A review of this and subsequent ACUS correspondence demonstrates that the term “specific fact” refers to a category of legislative fact, the resolution of which may be aided by the type of adversarial procedures inherent in an evidentiary proceeding with limited cross-examination. See Citizens for Allegan County v. FPC, 134 U.S.App.D.C. 229, 233, 414 F.2d 1125, 1129 (D.C.Cir.1969).29 Nothing in the legislative history or background of section 18 suggests, however, that Congress believed that the use of evidentiary hearings transformed the nature of the proceedings from rulemaking to adjudication or altered the factual predicate of rulemaking from legislative to adjudicative fact. Accordingly, the appellees’ contention that the Cinderella standard must be applied to section 18 rulemaking because it invokes the same type of factual judgments as Commission adjudication is simply incorrect.
D
Our conclusion that neither the procedures nor the factual predicate of section 18 rulemaking converts it into adjudication is supported by United States v. Florida East Coast Railway, 410 U.S. 224, 93 S.Ct. 810, 35 L.Ed.2d 223 (1973). In that case, the Su[1165]*1165preme Court held, over the protests of two dissenting Justices, that an Interstate Commerce Commission ratemaking proceeding was rulemaking. The dissent maintained that the rate order was “adjudicatory in the sense that [it] determine[d] the measure of the financial responsibility of one road for its use of the rolling stock of another road.” Id. at 252, 93 S.Ct. at 824 (Douglas, J., joined by Stewart, J., dissenting). The dissent emphasized that the agency decision was based on “evidential facts,” id. at 254, 93 S.Ct. at, and that it could “have devastating effects on a particular [railroad] line,” id. at 256, 93 S.Ct. at 826. Nevertheless, the Court found that the proceeding was rulemaking because the agency final order was applicable to all common carriers rather than any particular railroad. The Court explained that the agency had predicated its decision on “factual inferences . . . used in the formulation of a basically legislative-type judgment, for prospec-. tive application only, rather than in adjudicating a particular set óf disputed facts.” Id. at 246, 93 S.Ct. at 821.
The same analysis applies to section 18 rulemaking. A section 18 proceeding is directed to all members of an affected industry and is based on legislative fact. Even when evidentiary procedures are employed in the formulation of specific fact, the product of those procedures is “used in the formulation of a basically legislative-type judgment.” Id. Although we recognize that the line between rulemaking and adjudication “may not always be a bright one,” id. at 245, 93 S.Ct. at 821, we have no doubt that section 18 proceedings fall clearly on the rulemaking side of the “recognized distinction in administrative law between proceedings for the purpose of promulgating policy-type rules ... on the one hand, and proceedings designed to adjudicate disputed facts in particular cases on the other.” Id. Accordingly, we now decide the standard of disqualification applicable in a section 18 rulemaking proceeding.
IV
Had Congress amended section 5 of the FTC Act to declare certain types of children’s advertising unfair or deceptive, we would barely pause to consider a due process challenge. No court to our knowledge has imposed procedural requirements upon a legislature before it may act. Indeed, any suggestion that congressmen may not prejudge factual and policy issues is fanciful. A legislator must have the ability to exchange views with constituents and to suggest public policy that is dependent upon factual assumptions. Individual interests impinged upon by the legislative process are protected, as Justice Holmes wrote, “in the only way that they can be in a complex society, by [the individual’s] power, immediate or remote, over those who make the rule.” Bi-Metallic Investment Co. v. State Board of Equalization, 239 U.S. 441, 445, 36 S.Ct. 141, 142, 60 L.Ed. 372 (1915).
Congress chose, however, to delegate its power to proscribe unfair or deceptive acts or practices to the Commission because “there were too many unfair practices for it to define.” S.Rep.No. 597, 63d Cong., 2d Sess. 13 (1914).30 In determining the due process standards applicable in a section 18 proceeding, we are guided by its nature as rulemaking.31 When a proceeding is classified as rulemaking, due process [1166]*1166ordinarily does not demand procedures more rigorous than those provided by Congress. See Vermont Yankee Nuclear Power Corp. v. NRDC, 435 U.S. 519, 524 & n. 1, 542 & n. 16, 98 S.Ct. 1197, 55 L.Ed.2d 460 (1978). Congress is under no requirement to hold an evidentiary hearing prior to its adoption of legislation, and “Congress need not make that requirement when it delegates the task to an administrative agency.” Bowles v. Willingham, 321 U.S. 503, 519, 64 S.Ct. 641, 649, 88 L.Ed. 892 (1944) (citing Bi-Metallic Investment Co. v. State Board of Equalization, 239 U.S. 441, 36 S.Ct. 141, 60 L.Ed. 372 (1915)). Accordingly, we must apply a disqualification standard that is consistent with the structure and purposes of section 18.
Congress regarded the authority to promulgate rules pursuant to section 18 as an “important power by which the Commission can fairly and efficiently pursue its important statutory mission.” H.R.Rep.No. 93-1606, supra at 31.32 Through rulemaking, the Commission may allocate resources more efficiently, act with greater speed, and give specific notice to industries of the scope of section 5. See National Petroleum Refiners Association v. FTC, 157 U.S.App.D.C. 83, 101-102, 482 F.2d 672, 690-91 (D.C.Cir.1973), cert. denied, 415 U.S. 951, 94 S.Ct. 1475, 39 L.Ed.2d 567 (1974).33 More important, rulemaking allows an agency to gather information and views that might be irrelevant to the narrowly focused concerns of adjudication:
[Utilizing rule-making procedures opens up the process of agency policy innovation to a broad range of criticisms, advice [1167]*1167and data that is ordinarily less likely to be forthcoming in adjudication. Moreover, the availability of notice before promulgation and wide public participation in rule-making avoids the problem of singling out a single defendant among a group of competitors for initial imposition of a new and inevitably costly legal obligation.
Id. at 683.
In determining the type of rulemaking procedures to be employed by the Commission, Congress sought “to avoid rigid or cumbersome procedures that could involve undue costs and delay.” H.R.Rep.No.93-1606, supra at 33. To this end, Congress gave the Commission authority to limit rebuttal and cross-examination. In so acting, Congress heeded the advice of ACUS, which, when asked to comment upon the House proposal, warned that requiring “trial-type procedures . . . [in] rulemaking of general applicability [may] produce a virtual paralysis of the administrative process.” 34
Although Congress refused to subject section 18 proceedings to formal rulemaking requirements, it did order use of procedures not required in informal rulemaking under the APA.35 Congress intended these addi[1168]*1168tional procedures “to improve the quality of information available to the Commission,” H.R.Rep.No. 93-1606, supra at 33, and to compel reexamination of the proposed rule in light of the arguments adduced during the comment period. Incorporation of this information into a rulemaking record also allows a reviewing court to exercise meaningful supervision over the Commission’s decision.
We never intended the Cinderella rule to apply to a rulemaking procedure such as the one under review. The Cinderella rule disqualifies a decisionmaker if “ ‘a disinterested observer may conclude that [he] has in some measure adjudged the facts as well as the law of a particular case in advance of hearing it.’ ” 138 U.S.App.D.C. at 160, 425 F.2d at 591 (quoting Gilligan, Will & Co. v. SEC, 267 F.2d at 469). As we already have noted,36 legislative facts adduced in rule-making partake of agency expertise, prediction, and risk assessment. In Cinderella, the court was able-to cleave fact from law in deciding whether Chairman Dixon had prejudged particular factual issues. In the rulemaking context, however, the factual component of the policy decision is not easily assessed in terms of an empirically verifiable condition. Rulemaking involves the kind of issues “where a month of experience will be worth a year of hearings.”37 Application of Cinderella’s strict law-fact dichotomy would necessarily limit the ability of administrators to discuss policy questions.
The legitimate functions of a policymaker, unlike an adjudicator, demand interchange and discussion about important issues. We must not impose judicial roles upon administrators when they perform functions very different from those of judges. As Professor Glen O. Robinson, a former member of the Federal Communications Commission, has commented:
Although members of agencies such as the FCC certainly do perform significant judicial functions in deciding individual cases, they perform even more tasks of a legislative or an executive character. When the FCC, for example, promulgated regulations barring common ownership of local newspapers and broadcast stations, it performed a legislative task, pure and simple. In reaching the decision, the Commission was neither bound by, nor expected to conform to, the confining procedures or standards of a court. Why then should the decisionmakers be stamped from a judicial cast? Insofar as the agency is delegated broad legislative powers and responsibilities, would it not be at least as appropriate to measure agency members against standards used to evaluate legislators? Such standards would place agency members on a better standing with respect to judges and would create an entirely new frame of reference for assessing agency performance. The supremacy of carefully reasoned principle — the supposed ideal of judicial decision — necessarily would yield to the dictates of political compromise and expediency, which are the accepted hallmarks of legislative action. Correspondingly, the standard for evaluating the composition of the agencies would shift from an emphasis on professional training to an emphasis on representativeness.
Robinson, The Federal Communications Commission: An Essay on Regulatory Watchdogs, 64 Va.L.Rev. 169, 185-86 (1978) (footnotes omitted).38
The Cinderella view of a neutral and detached adjudicator is simply an inapposite [1169]*1169role model for an administrator who must translate broad statutory commands into concrete social policies.39 If an agency official is to be effective he must engage in debate and discussion about the policy matters before him. As this court has recognized before, “informal contacts between agencies and the public are the ‘bread and butter’ of the process of administration.” Home Box Office, Inc. v. FCC, 185 U.S.App.D.C. 142, 190, 567 F.2d 9, 57 (D.C.Cir.) (per curiam), cert. denied, 434 U.S. 829, 98 S.Ct. 111, 54 L.Ed.2d 89 (1977).40
Our view is consistent with two Supreme Court opinions that detail prejudgment standards for administrators who speak out on public policy matters. In Hortonville Joint School District No. 1 v. Hortonville Education Association, 426 U.S. 482, 96 S.Ct. 2308, 49 L.Ed.2d 1 (1976), the Court held that the due process clause did not bar a local school board, which was negotiating renewal of a collective-bargaining agreement with teachers, from dismissing teachers who were engaged in an illegal strike following failure of the contract negotia[1170]*1170tions.41 The Court stated that a decision-maker need not be disqualified “simply because he has taken a position, even in public, on a policy issue related to the dispute, in the absence of a showing that he is not ‘capable of judging a particular controversy fairly on the basis of its own circumstances.’ ” Id. at 493, 96 S.Ct. at 2314 (quoting United States v. Morgan, 313 U.S. 409, 421, 61 S.Ct. 999, 85 L.Ed. 1429 (1941)).
The Court’s decision in FTC v. Cement Institute, 333 U.S. 683, 68 S.Ct. 793, 92 L.Ed. 1010 (1948), is likewise instructive. There, a trade association urged that the Commission be disqualified from deciding whether a trade practice violated the antitrust laws because its members previously had endorsed the view before both the Congress and the President that the practice was the equivalent of illegal price-fixing. The Court rejected the trade association’s claim because, inter alia, the earlier statements “did not necessarily mean that the minds of [Commission] members were irrevocably closed.” Id. at 701, 68 S.Ct. at 803.42
A similar standard is applicable to section 18 rule-making. Section 18 outlines a process by which the Commission must form a preliminary view on a proposed rule, must hear comment from concerned parties, and in some cases, must hold trial-type proceedings before deciding whether to promulgate a rule. There is no doubt that the purpose of section 18 would be frustrated if a Commission member had reached an irrevocable decision on whether a rule should be issued prior to the Commission’s final action. At the same time, the Commission could not exercise its broad policymaking power under section 18 if administrators were unable to discuss the wisdom of various regulatory positions. That discussion necessarily involves the broad, general characterizations of reality that we label legislative fact.
Accordingly, a Commissioner should be disqualified only when there has been a clear and convincing showing that the agency member has an unalterably closed mind on matters critical to the disposition of the proceeding. The “clear and convincing” test is necessary to rebut the presumption of administrative regularity. See, e. g., Withrow v. Larkin, 421 U.S. 35, 55, 95 S.Ct. 1456, 43 L.Ed.2d 712 (1975); Hercules, Inc. v. EPA, 194 U.S.App.D.C. 172, 204, 598 F.2d 91, 123 (D.C.Cir.1978). The “unalterably closed mind” test is necessary to permit rulemakers to carry out their proper policy-based functions while disqualifying those unable to consider meaningfully a section 18 hearing.43
V
We view the statements offered as grounds for disqualification as a whole to discern whether they evidence a clear and convincing showing that Chairman Pertschuk has an unalterably closed mind on [1171]*1171matters critical to the children’s television proceeding. The most important evidence submitted by the appellees is a speech Chairman Pertschuk delivered in November 1977 to the ACT Research Conference. The other materials generally derive from this speech.44
The speech focused on whether section 5 of the FTC Act, which prohibits “unfair or deceptive acts or practices,” may be applicable to children’s advertising. Pertschuk first asserted that children have only a minimal understanding of the nature of television commercials and are unable to distinguish between advertising and other forms of information. He quoted a finding by the Federal Communications Commission that “many children do not have the sophistication or experience needed to understand that advertising is not just another form of informational programming.” 45
Pertschuk then set out relevant legal principles. He quoted a Supreme Court opinion that gave the Commission wide-ranging discretion to declare a trade practice unfair.46 He noted the legal recognition of children’s lack of evaluative capacity and the concomitant protection for children built into commercial and tort law. Among the doctrines he mentioned were the unenforeeability of a contract signed by a child, the prohibition against selling children otherwise legal goods, such as liquor and cigarettes, the bar against children leaving school or driving a car, and the “attractive nuisance” rule of liability, which holds persons who maintain conditions on their property that are likely to entice small children responsible for harm to those children.
Pertschuk continued by discussing the effects of advertising on children. He explained that “children are not adults in miniature. Instead, they bring to advertising a special perspective and sensibility — a credulousness that comes from inexperience — which advertisers exploit.”47 He stated that sugared foods may be harmful to children and that children may not understand the health problems, like tooth decay, that can result from excessive consumption of sugared products: “Children lack the judgment and experience to see that something that looks good to them in the short run can hurt them in the long run.”48 He suggested that children’s advertising might be deceptive because it highlights the general desirability of sugared foods without providing material information on the health risks.
Finally, Pertschuk noted that any action taken against children’s advertising would bring opposition from affected economic interests. He said that “[i]f the Commission is to reach sound and reasoned judgments, it must also hear from the parents, the teachers, the pediatricians, the dentists, those health and education specialists on whom we rely for the advocacy of our children’s best interest.” 49 Pertschuk concluded by stating: “[W]e must be rigorous and open-minded in our analysis of both law and fact.”50
Chairman Pertsehuk’s remarks, considered as a whole, represent discussion, and perhaps advocacy, of the legal theory that might support exercise of the Commission’s jurisdiction over children’s advertising. The mere discussion of policy or advocacy on a legal question, however, is not sufficient to disqualify an administrator.51 [1172]*1172To present legal and policy arguments, Pertschuk not unnaturally employed the factual assumptions that underlie the rationale for Commission action. The simple fact that the Chairman explored issues based on legal and factual assumptions, however, did not necessarily bind him to them forever. Rather, he remained free, both in theory and in reality, to change his mind upon consideration of the presentations made by those who would be affected.
In outlining his legal theory of “unfairness,” Pertschuk suggested that children might be harmed by overconsumption of sugared products and that they might not be able to comprehend the purpose of advertising. Insofar as these conclusions are ones of fact, they are certainly of legislative fact. Neither conclusion bears on the particular activities of any specific advertiser or food manufacturer or makes reference to the health or comprehension of any particular child. These conclusions are broad and general, far removed from the narrow, detailed facts that were at the heart of the Cinderella case.52
Together, the two conclusions tend to show that children may be “injured” by the advertising of highly sugared products. The Commission has stated that it will consider three factors in deciding whether a trade practice is unfair: whether the action is (1) offensive to public policy as established by some legal doctrine, (2) immoral, and (3) substantially injurious to consumers.53 Chairman Pertschuk scarcely could [1173]*1173have discussed the “unfairness” doctrine without assuming for the purpose of discussion that some injury might result from the trade practice in question.
We also note that Chairman Pertschuk made the challenged comments before the Commission adopted its notice of proposed rulemaking. This court has never suggested that the interchange between rulemaker and the public should be limited prior to the initiation of agency action.54 The period before the Commission first decides to take action on a perceived problem is, in fact, the best time for a rulemaker to engage in dialogue with concerned citizens. Discussion would be futile, of course, if the administrator could not test his own views on different audiences. Moreover, as we stated earlier,55 an expression of opinion prior to the issuance of a proposed rulemaking does not, without more, show that an agency member cannot maintain an open mind during the hearing stage of the proceeding.
Indeed, section 18 in effect requires the Commission to formulate tentative judgments on suggested rules. Before the Commission initiates rulemaking proceedings, it must “publish a notice of proposed rulemaking stating with particularity the reason for the proposed rule prior to the comment stage of the' proceeding.” 15 U.S.C. § 57a(b). The Conference Committee on the Magnuson-Moss Act referred to the period following this notice as one during which affected parties could “challenge the factual assumptions on which the Commission is proceeding and to show in what respect these assumptions are erroneous.” H.R.Rep.No. 93-1606, supra at 33. Congress intended for the Commission to develop proposals that subsequently would be published and discussed openly. To perform this task intelligently necessarily involves making tentative conclusions of fact, even if they later are open to public challenge.
In sum, we hold that the materials adduced by the appellees are insufficient to rebut the strong presumption of administrative regularity.56 The materials, as a [1174]*1174whole, merely demonstrate that Pertschuk discussed a legal theory by which the Commission could adopt a rule, if circumstances warranted. The statements do not demonstrate that Chairman Pertschuk is unwilling or unable to consider rationally argument that a final rule is unnecessary because children are either unharmed by sugared products or are able to understand advertising. The appellees have failed to make a clear and convincing showing that Chairman Pertschuk has an unalterably closed mind on matters critical to the children’s television proceeding.
VI
The appellees have a right to a fair and open proceeding; that right includes access to an impartial decisionmaker. Impartial, however, does not mean uninformed, unthinking, or inarticulate. The requirements of due process clearly recognize the necessity for rulemakers to formulate policy in a manner similar to legislative action. The standard enunicated today will protect the purposes of a section 18 proceeding, and, in so doing, will guarantee the appellees a fair hearing.
We would eviscerate the proper evolution of policymaking were we to disqualify every administrator who has opinions on the correct course of his agency’s future action. Administrators, and even judges, may hold policy views on questions of law prior to participating in a proceeding. The factual basis for a rulemaking is so closely intertwined with policy judgments that we would obliterate rulemaking were we to equate a statement on an issue of legislative fact with unconstitutional prejudgment. The importance and legitimacy of rulemaking procedures are too well established to deny administrators such a fundamental tool.
Finally, we eschew formulation of a disqualification standard that impinges upon the political process. An administrator’s presence within an agency .reflects the political judgment of the President and Senate. As Judge Prettyman of this court aptly noted, a “Commission’s view of what is best in the public interest may change from time to time. Commissions themselves change, underlying philosophies differ, and experience often dictates changes.” Pinellas Broadcasting Co. v. FCC, 97 U.S.App.D.C. 236, 238, 230 F.2d 204, 206 (D.C.Cir.), cert. denied, 350 U.S. 1007, 76 S.Ct. 650, 100 L.Ed. 869 (1956). We are concerned that implementation of the Cinderella standard in the rulemaking context would plunge courts into the midst of political battles concerning the proper formulation of administrative policy. We serve as guarantors of statutory and constitutional [1175]*1175rights, but not as arbiters of the political process. Accordingly, we will not order the disqualification of a rulemaker absent the most compelling proof that he is unable to carry out his duties in a constitutionally permissible manner.
