SAM D. JOHNSON, Circuit Judge:
Tales of the violence of white sheeted Southerners prompted Congress to pass the Ku Klux Klan Act of 1871. Today this Court is asked to decide whether one of the offspring of that Act, 42 U.S.C. § 1985(2),1 provides relief for individuals who allege they are unable to obtain employment in the oil drilling industry because they filed personal injury claims against companies in that industry. The district court, 445 F.Supp. 269, held as a matter of law that the statute does not cover this alleged blacklisting and granted summary judgment for defendants. We affirm in part and reverse in part.
I. The Facts
The Industrial Foundation of the South (the Foundation) is a non-profit corporation that assists its member companies, all affiliated with the oil industry, in making personnel decisions. Specifically, the Foundation checks court records in Louisiana, Texas, Mississippi, Alabama, Oklahoma, New Mexico, and Missouri to discover all claims filed against companies in the oil industry for injuries resulting from employment.2 The Foundation then compiles a list of the individuals who have filed suit in federal or state courts, as well as those who have sought workers’ compensation pursuant to federal or state law.3 Whenever someone applies for employment with one of the approximately 300 subscribers to the Foundation’s services, the person handling the job application notifies the Foundation and provides the Foundation with the prospective employee’s name and social security number.4 The Foundation searches through its one-half million records and supplies the requesting company with any pertinent information that it has on the applicant. Using this information as a guideline, the employer then makes an appropriate employment decision.
One of the individuals whose record may be found in the Foundation’s files is the named plaintiff in this cause of action, Ver-sie Kimble. In 1969 Kimble injured his right shoulder while working for Noble Drilling Company. He filed suit in federal court and, after a jury trial, recovered $35,-000. In December 1972, Kimble began working for D. J. McDuffy, Inc. (McDuffy), a now-defunct oil well service company. At the time McDuffy hired Kimble, the company was not a member of the Industrial Foundation of the South. In March 1973 McDuffy joined the Foundation. Shortly thereafter, in early April, McDuffy fired Versie Kimble. McDuffy contended that it terminated Kimble because he was about to seek political office. Kimble claims he was fired because of his prior suit against Noble Drilling Company.
On May 13, 1973, Versie Kimble filed this class action on behalf of all individuals who had been denied employment by Foundation members because they had filed workers’ compensation or personal injury claims against companies affiliated with the oil [1063]*1063drilling industry. The defendants included D. J. McDuffy, Inc., the Industrial Foundation of the South, and all members of the Foundation. The complaint, based entirely on 42 U.S.C. § 1985(2),5 sought damages for the class and a permanent injunction enjoining defendants from continuing their allegedly unlawful practices.6 The district court denied class action status with respect to the damage claim, but certified the class with respect to the claim for injunctive relief.
In January 1978 the district court considered the defendants’ motion for summary judgment. The district court gave plaintiffs the benefit of all assumptions and drew all inferences in favor of the plaintiffs. After thoroughly examining Section 1985(2), the district court concluded that the statute does not cover the actions that plaintiffs complained of, and held that the defendants were entitled to judgment as a matter of law. Kimble v. D. J. McDuffy, Inc., 445 F.Supp. 269 (E.D.La.1978). Plaintiff then instituted this appeal.
II. Statutory History
The starting point for delineating the coverage provided by section 1985(2) is the section’s statutory roots. See Brawer v. Horowitz, 535 F.2d 830 (3d Cir. 1976). The parent of Section 1985 is Section 2 of the Ku Klux Klan Act.7 Act of April 20, 1871, Ch. 22, § 2,17 stat. 13. In 1874, pursuant to [1064]*1064Congressional authorization, Secretary of State Hamilton Fish supervised the revision and publication of all the statutes of the United States. During the course of that revision, minor grammatical changes were made and Section 2 of the Ku Klux Klan Act was reformulated into three subsections. Brawer 535 F.2d at 838, 839. The reformulated version of Section 2 of the Ku Klux Klan Act made its way into the revised statutes as Section 1980. The current language of Section 1985, including Section 1985(2), is taken verbatim from Revised Statutes § 1980, Second.
Section 1985(2) was once part of a unitary statutory scheme designed to protect individuals from a wide range of conspiracies. Thus, in seeking to interpret the language of Section 1985(2), courts must be guided by prior interpretations of similar language found in Section 2 of the Ku Klux Klan Act, specifically those provisions that today constitute 1985(1) and (3).
III. The Section 1985(2) Cause of Action
A. Analytical Framework The issue before this Court is whether plaintiffs produced sufficient evidence to survive defendants’ motion for summary judgment. A careful analysis of the various provisions of Section 1985(2) and an application of the facts to those provisions is required in order to resolve this question. In conducting this examination, we must approach the “perfidious syntax” of Section 1985(2) with some care. Brawer, 535 F.2d at 837. The statute contains several different provisions, no two of which are directed at the same type of conspiracy. As the district court noted, when one omits the clauses in Section 1985(2) that are applicable to juries and jurors (and inapplicable in the case at bar), subsection 2 contains four clauses that create four distinct causes of action:
A. If two or more persons conspire to deter, by force, intimidation, or threat, any party or witness in any court of the United States from attending such court, or from testifying to any matter pending therein . or
B. to injure such party or witness in his person or property on account of his having so attended or testified, or
[1065]*1065C. if two or more persons conspire for the purpose of impeding, hindering, obstructing, or defeating, in any manner, the due course of justice in any State or Territory, with intent to deny to any citizen the equal protection of the laws, or
D. to injure him or his property for lawfully enforcing . . . the right of any person, or class of persons, to the equal protection of the laws.
445 F.Supp. at 274. In determining whether plaintiffs’ claim should have survived a motion for summary judgment, this Court must examine each of these four clauses individually.
B. Clause C
Clause C of Section 1985(2) is aimed at conspiracies designed to obstruct “the due course of justice in any State or Territory.” The conspiracy must be entered into with the intent to deny “equal protection of the laws . . . The district court held that plaintiffs failed to allege or show a conspiracy entered into with the intent to deny them equal protection of the law. We agree.
Exactly what evidence is required to establish that defendants entered into a conspiracy with the intent of denying plaintiffs equal protection of the law is not readily apparent. The starting point for this inquiry must be the Supreme Court’s interpretation of similar language from Section 1985(3) in Griffin v. Breckenridge, 403 U.S. 88, 91 S.Ct. 1790, 29 L.Ed.2d 338 (1971). Although the Supreme Court in Griffin was focusing on the language of Section 1985(3), this Court has held that, in light of its statutory roots,8 clause C is to be interpreted in accordance with Griffin. Slavin v. Curry, 574 F.2d 1256, 1262, modified 583 F.2d 779 (5th Cir. 1978).
Griffin involved an assault on blacks traveling a Mississippi highway by white private citizens. The attack was racially motivated — defendants acted on the mistaken belief that the plaintiffs were civil rights workers. The issue in Griffin was whether Section 1985(3) created a cause of action for damages against individuals acting in a purely private capacity.
The Court held that Section 1985(3) was designed to protect individuals from actions by private persons. The Court recognized, however, that Section 1985(3) was not “intended to apply to all tortious, conspiratorial interferences [by private parties] with the rights of others.” Id. 403 U.S. at 101, 102, 91 S.Ct. at 1798. “The language requiring intent to deprive of equal protection, or equal privileges and immunities, means that there must be some racial, or perhaps otherwise class-based, animus behind the conspiratorial actions.” Id. at 102, 91 S.Ct. at 1798 (footnote omitted). Thus, since defendants in the case at bar are private parties, in determining whether plaintiffs have satisfied the requisites of clause C this Court must determine whether plaintiffs have established that defendants were motivated by the appropriate class-based, discriminatory animus.
We note from the start that not all classes of individuals fall within the protective cloak of clause C. See, e. g., McLellan v. Mississippi Power & Light Co., 545 F.2d 919 (5th Cir. 1977) (en banc) (persons who have voluntarily filed a bankruptcy petition are not a protected class); Bricker v. Crane, 468 F.2d 1228 (1st Cir. 1972), cert. denied, 410 U.S. 930, 93 S.Ct. 1368, 35 L.Ed.2d 592 (1973) (doctors who have testified against their brethren in malpractice cases are not a protected class). The class that plaintiffs allege is the target of defendants’ conspiracy is one that includes workers employed in the oil exploration industry who have pursued some type of personal injury claim. While personal injury claimants are undoubtedly a class for some purposes, the question in the case at bar is whether Congress intended to proscribe a conspiracy to obstruct the due course of justice aimed at persona] injury claimants. A careful review of Congressional intent and the subsequent jurisprudence establishes that Section 1985(2), clause C was not designed to protect this class of plaintiffs.
[1066]*1066There are two distinct genres of classes protected by clause C. The first category is defined by some courts as one where the class is characterized by some inherited or immutable characteristic. Perhaps the better definition is that recently endorsed by the Ninth Circuit in DeSantis v. Pacific Telephone & Telegraph Co., Inc., 608 F.2d 327 (9th Cir. 1979). The Ninth Circuit held that in determining whether a group of individuals satisfies the class requirement of 1985(3), federal courts have remained faithful to the basis principle underlying the adoption of Section 2 of the Ku Klux Klan Act: “The governmental determination that some groups require and warrant special federal assistance in protecting their civil rights.” Id. at 333. Cf. Monroe v. Pape, 365 U.S. 167, 81 S.Ct. 473, 5 L.Ed.2d 492 (1963) (Although the civil rights statutes were enacted in response to post-war conditions in the South, they are cast in general language and provide for flexibility).
The Supreme Court focused on the most obvious of this type of protected class in Griffin, when the Court held that conspirators who acted with a racially discriminatory animus could be found to be in violation of Section 1985(3).9 Lower federal courts have extended this first category beyond race to encompass those who are victims of a conspiracy due to their sex, Life Insurance Company of North America v. Rei-chardt, 591 F.2d 499 (9th Cir. 1979); Curran v. Portland Superintending School Committee, 435 F.Supp. 1063 (D.Maine 1977); religion, Marlowe v. Fisher Body, 489 F.2d 1057 (6th Cir. 1973); or national origin, Id.10
Plaintiffs are unable to establish that Congress or the judiciary has displayed a special solicitude towards their class because of its need for assistance in enforcing its civil rights. While this Court recognizes that the protective scope of the Act is not static, a class composed of personal injury claimants does not fall within this first category of classes protected by Section 1985(2), clause C.
There is a second category of classes encompassed by Sections 1985(2) and (3). This category includes individuals who are victims of a conspiracy because of their political beliefs or associations.
That Congress intended to protect individuals who are conspired against because of their political beliefs or associations is beyond doubt. Although the Ku Klux Klan is today thought of as a racist organization, in 1871 it was primarily a political organization. The Republicans, who controlled the 42d Congress, found Klan violence especially troublesome because they were convinced that it was politically motivated. Comment, A Construction of Section 1985(c) in Light of Its Original Purpose, 46 Univ.Chi. L.Rev. 402, 408 (1979). The majority report of the Senate Select Committee to Investigate Alleged Outrages in the Southern States reflected this concern: “[I]t is clearly established . . . that the Ku Klux Organization does exist, has a political purpose, is composed of members of the democratic or conservative party, [and] has sought to carry out its purpose by murders, whippings, intimidations, and violence.” H.R.Rep.No. 1, 42d Cong. 1st Sess. XXX-XXXI. The need to protect individuals being harassed because of their political associations rang throughout the Congressional debate. Senator George Edmunds of Vermont, who reported the bill out of committee, stated that:
We do not undertake in this bill to interfere with what might be called a private conspiracy growing out of a neighborhood feud of one man or set of men against another to prevent one getting an indictment in the State courts against men for burning down his barn; but, if in a case like this, it should appear, that this con[1067]*1067spiracy was formed against this man because he was a Democrat, if you please, or because he was a Catholic, or because he was a Methodist, or because he was a Vermonter, (which is a pretty painful instance that I have in mind in the State of Florida within a few days where a man lost his life for that reason,) then this section could reach it.
42d Cong., 1st Sess. 567 (1871), reprinted in A. Avins, The Reconstruction Amendments Debates 547 (1967) (emphasis added). Representative Ellis Roberts repeated this same concern when discussing, in the House, the need for legislation.
But one rule never fails: the victims whose property is destroyed, whose persons are mutilated, whose lives are sacrificed, are always Republicans. They may be black or white; they include those who wore the blue and those who wore the gray; new-comers and life-long residents, but only Republicans. Stain the door lintels with the mark of opposition to reconstruction and of hostility to the national Administration, and the destroying angel passes by. Omit that sign, and the torch may kindle the roof that covers women and children; the scourge may fall upon shoulders that stoop with weakness and with age; the bullet may pierce the breast without warning. Such uniformity of result can come only from design. Republicans only are beaten and mutilated and murdered, because the blows are aimed at Republicans only.
Cong.Globe, 42d Cong., 1st Sess., 412-413 (1871) (emphasis added).
Federal courts have recognized that those who are discriminated against because of political views or associations fall with the protective scope of Section 1985(2) and (3). Courts have found a class-based animus sufficient to support causes of action where the conspiracy is directed toward supporters of a particular political candidate, Cameron v. Brock, 473 F.2d 608 (6th Cir. 1973) and Means v. Wilson, 522 F.2d 833 (8th Cir. 1975), cert. denied, 424 U.S. 958, 96 S.Ct. 1436, 47 L.Ed.2d 364 (1976); voters who were deceived about the actual effect of their vote, Smith v. Cherry, 489 F.2d 1098 (7th Cir. 1973), cert. denied 417 U.S. 910, 94 S.Ct. 2607, 41 L.Ed.2d 214 (1974); individuals critical of the President and his policies, Glasson v. City of Louisville, 518 F.2d 899 (6th Cir.), cert. denied 423 U.S. 930, 96 S.Ct. 280, 46 L.Ed.2d 258 (1975); members of a group advocating an unpopular position, Puentes v. Sullivan, 425 F.Supp. 249 (W.D. Tex.1977); laborers who are not members of a union, Scott v. Moore, 461 F.Supp. 224 (E.D.Tex.1978); members of the teaching profession who talk or associate with the CIA, Selzer v. Berkowitz, 459 F.Supp. 347 (E.D.N.Y.1978); and students who exercise their first amendment rights by joining certain organizations, Brown v. Villanova University, 378 F.Supp. 342 (E.D.Pa.1974).
Unfortunately for plaintiffs in the case at bar, this second category is of little assistance. Plaintiffs have provided no summary judgment evidence to establish that they are victims of a conspiracy because of their political views or associations. Rather, even assuming a conspiracy exists, the record indicates that the conspiracy is directed at plaintiffs because they filed personal injury claims. This is simply not the type class that is protected by the statute.
In summary, plaintiffs have not established the class-based, discriminatory animus that is required for a cause of action under Section 1985(2), clause C. The district court’s grant of summary judgment on this portion of subsection (2) is affirmed.11
C. Clause D
Clause D is aimed at conspiracies against individuals because the individuals lawfully enforce the right of any person or [1068]*1068class of persons to equal protection. The courts that have construed this clause have universally noted that it is directed toward “equal protection of the laws,” the key phrase in the Supreme Court’s Griffin analysis. See, e. g., Hahn v. Sargent, 523 F.2d 461, 469 (1st Cir. 1975); Brawer v. Horowitz, 535 F.2d 830, 840 (3d Cir. 1976). The courts have required that plaintiffs establish a class-based invidiously discriminatory animus in order to prevail under this clause of Section 1985(2). As this Court noted above, plaintiffs have failed to establish that there was an appropriate class-based, discriminatory animus in the case at bar. Accordingly, the district court’s grant of summary judgment for defendants on this clause is also affirmed.
D. Clause A
Clause A is aimed at conspiracies to deter parties or witnesses from attending or testifying in any court of the United States. The district court granted summary judgment for defendants on this clause because plaintiffs failed to offer any evidence indicating that defendants attempted to deter a witness or party from attending or testifying in court. We agree.
Plaintiffs contend that defendants conspired not to hire anyone who had asserted a personal injury claim against a member of the oil industry. In essence, they assert that defendants’ conspiracy is retaliatory in nature. However, plaintiffs have offered nothing to indicate that this retaliatory conspiracy has deterred anyone from attending or testifying in court. The district court’s grant of summary judgment on this clause of Section 1985(2) is affirmed.
E. Clause B
The second clause of Section 1985(2), clause B, creates a cause of action against individuals who conspire to injure a party or witness for having attended or testified in any court of the United States. The district court granted summary judgment for defendants on this clause because plaintiffs did not allege that they were injured because they attended or testified in court, but rather only that they were injured because they filed claims. The district court’s conclusion is apparently premised on its belief that the phrase “attended or testified” requires actual physical presence in a courtroom. We reject such a narrow reading of the statute.
Congress recognized that conspiracies designed to injure parties who turn to the courts can only produce a misapplication of the federal judicial system. Congress enacted the first part of Section 1985(2) in order to protect the sanctity of federal court proceedings and prevent miscarriages of justice. The justice provided by our judicial system, however, does not start on the day of trial. The process of obtaining justice in the court system begins long before a case is called to trial — it is initiated at the moment a party files a complaint. Congress undoubtedly intended to protect the whole course of justice, not just one segment of the system, the trial process. Thus, for the purposes of Section 1985(2) an individual is deemed to have “attended” a court of the United States from the moment that the person files a complaint.
Congress certainly did not exceed constitutional bounds when it provided that an individual “attends” federal court when a complaint is filed. U.S.Const. art. Ill provides for a federal judiciary and U.S.Const. art. 1, § 8, cl. 18, provides that Congress shall have the power to make laws necessary and proper for executing all powers vested by the Constitution and the government of the United States. It is beyond question that Congress has the power to do what it did in the first part of Section 1985(2) — protect the federal judicial system from efforts to obstruct justice. See McCulloch v. Maryland, 17 U.S. 316, 4 Wheat. 316, 4 L.Ed. 579 (1819).
Defendants contend that, even if the first part of Section 1985(2) is read expansively, plaintiff is still not entitled to relief for two reasons. Initially, defendants argue that the Griffin requirement of a class-based, invidiously discriminatory animus is [1069]*1069also required by Section 1985(2), clause B. A careful reading of Griffin and the statute does not support defendants’ argument.
The invidious animus requirement of Griffin is a test established for determining whether a conspiracy was designed to deprive “any person or class of persons of the equal protection of the laws, or of equal privileges and immunities under the laws,” as required by Section 1985(3). Unlike Section 1985(3) and clauses C and D of Section 1985(2), clause B of Section 1985(2) is not limited to conspiracies aimed at the deprivation of equal protection or equal privileges and immunities. There is no reference whatsoever in the first part of Section 1985(2) to the term equal protection. Although defendants urge that we read the Griffin limitation into the first part of Section 1985(2), neither the statute nor the legislative history will support such an interpretation. The presence of the invidious animus requirement in Section 1985(3) and clauses C and D is persuasive evidence that Congress knew how to impose that limitation when it was intended. See, Stern v. United States Gypsum, Inc., 547 F.2d 1329 (7th Cir.), cert. denied, 434 U.S. 975, 98 S.Ct. 533, 54 L.Ed.2d 467 (1977) (holding Griffin inapplicable to Section 1985(1)). This Court declines to impose the invidious animus requirement where Congress clearly did not intend for it to be applied.
Defendants’ second contention is that this Court’s decision in McLellan v. Mississippi Power & Light Co., 545 F.2d 919 (5th Cir. 1977) (en banc), should be applied in the case at bar. The issue in McLellan was whether an employee who was discharged from private employment because he filed a voluntary petition in bankruptcy stated a claim under Section 1985(3). This Court concluded that Section 1985(3) requires that the alleged acts of defendants must be illegal, independent of Section 1985(3).
If the object of the defendant’s conspiracy did not include a violation of some law (independent of Section 1985(3) itself) which protects the plaintiff, the conspiracy could not have deprived the plaintiff of the “protection of the laws.” Put more simply, there can only be a deprivation of the rights of a plaintiff when the action of the defendants is otherwise illegal.
Id. at 925. Defendants in the case at bar contend that plaintiffs have failed to satisfy the independent illegality requirement of McLellan.
This Court need not decide whether these plaintiffs have satisfied the McLellan requirement of independent illegality, because that requirement is not applicable to the first part of Section 1985(2). The McLellan court developed the independent illegality requirement when it examined the language of Section 1985(3) dealing with “equal protection of the laws,” and concluded that private persons can only deprive others of equal protection of the laws by violating a law already in existence. In the first part of Section 1985(2), as we noted above when discussing the applicability of Griffin, there is no mention of the term “equal protection of the laws.” This Court must assume that Congress omitted the term “equal protection” from the first part of Section 1985(2) because it did not intend for the limitations associated with that phrase to be applicable to it. Defendants’ argument that McLellan should be applied is rejected.
Thus, in order to survive defendants’ motion for summary judgment, plaintiffs need only raise a factual question about whether defendants injured them on account of their having attended or testified in court. Plaintiffs have done this. Plaintiffs’ summary judgment evidence establishes that defendants refused to hire them because they filed personal injury claims. If the trier of fact accepts plaintiffs’ version, plaintiffs would be entitled to relief under Section 1985(2). The district courts grant of summary judgment on this clause was partially inappropriate. See, Part IV.
IV. The Appropriate Class
Not all of the certified class of plaintiffs have a cause of action under clause B. Section 1985(2), clause B only provides a cause of action for individuals injured be[1070]*1070cause they attended or testified in any court of the United States. The term “any court of the United States” does not mean any court physically located in the United States, but rather denotes courts that are part of the federal judicial system. See Seeley v. Brotherhood of Painters, Decorators, and Paper Hangers of America, 308 F.2d 52 (5th Cir. 1962); 28 U.S.C.A. § 451 (Supp.1980). State worker’s compensation boards, state courts, and federal worker’s compensation boards are not included in the term “any court of the United States.” Id. Accordingly, the only plaintiffs that may avail themselves of Section 1985(2), clause B are those who allege they were victims of employment discrimination because they filed claims in federal court.
V. Conclusion
The district court’s grant of summary judgment against those plaintiffs who were allegedly discriminated against because they asserted a personal injury claim before a state workers compensation board, in state court, or before a federal workers compensation board is affirmed. The district court’s grant of summary judgment against plaintiffs who allege they were discriminated against because they filed a personal injury claim in federal court is reversed. These plaintiffs have a cause of action under Section 1985(2), clause B that survives summary judgment. The district court’s grant of summary judgment against plaintiff Versie Kimble on his claim for damages is also reversed. Kimble also has a cause of action for damages under clause B that survives summary judgment.
