WALD, Circuit Judge:
This appeal is from the district court’s grant of summary judgment for the defendant-appellees on the basis that the appellants failed to state a valid constitutional claim of involuntary servitude, a “taking” of property, or a denial of equal protection.1 The appellants — three individual attorneys who regularly request assignment of cases in the Family Division of the Superior Court of the District of Columbia for which the District pays attorney fees and an association of lawyers who practice before the Family Division — challenged the practices by which the superior court appoints counsel to represent indigent parents in neglect proceedings without reimbursement of any kind. The district court rejected the appellants’ challenges to these practices on the basis of their facial unconstitutionality, and further held that the appellants’ failure to formally and specifically take issue with the appellees’ statement of material facts in their cross-motion for summary judgment justified granting that motion with regard to the constitutional challenges based on the operation of the assignment system. While we agree that the superior court’s assignment system is not unconstitutional on its face, we reverse, in part, because we find that the district court erroneously concluded that no material issue of fact was involved as to the claim that the system’s effect in practice is so burdensome on a small segment of the bar as to constitute a violation of those lawyers’ fifth amendment rights.
I. Background
A. The Appointment Practices
Since 1970, the D.C.Code has provided that in child neglect and parental termination proceedings2 both parents and children [698]*698must be provided with appointed counsel if the parents are financially unable to obtain adequate representation. The relevant statute reads:
(1) When a child is alleged to be neglected or when the termination of the parent and child relationship is under consideration, the parent, guardian or custodian of the child named in the petition or in a motion to terminate is entitled to be represented by counsel at all critical stages of the proceedings, and, if financially unable to obtain adequate representation, to have counsel appointed in accordance with rules established by the Superior Court of the District of Columbia.
(2) ... The Division shall in every case involving a neglected child which results in a judicial proceeding, including the termination of the parent and child relationship ..., appoint a guardian ad litem who is an attorney to represent the child in such proceedings.3
Until October 1,1982, no funds were available to pay counsel appointed to represent indigent parents in neglect cases.4 Since then, limited funds have been appropriated for this purpose.5 Presently, counsel for both children and parents in neglect proceedings are paid $30 for each court appearance. Attorney compensation, however, is ' subject to the following limits: $100 per child-neglect case until disposition of the neglect petition; $60 for each review of a child-custody placement pursuant to a finding of neglect if the review is within two years of the original neglect disposition or if the child is under 6 years old; $30 for all other reviews; $100 for termination proceedings. Letter from the Honorable Gladys Kessler, supra note 4. No funds are provided for expert witnesses or investigative services.
Superior court rules implementing the statutory mandate that counsel be appointed to represent indigent parents provide:
Assignment of counsel shall be made by the Division from a list of attorneys prepared and maintained by the Division. Separate counsel shall be assigned to represent a child alleged to be neglected and his parents, guardian or custodian whenever they are financially unable to obtain adequate representation. In cases where the child and his parents, guardian or custodian are financially able to obtain adequate representation but have not retained counsel, the Division may appoint separate counsel and order the payment of reasonable attorneys’ fees in accordance with SCR-Neglect 27 or may appoint counsel for the child and direct his parents, guardian or custodian to retain private counsel for themselves within a specified period of time. In making appointments the Division shall wherever possi[699]*699ble obtain the same attorneys, if any, who represented the child and the child’s parents, guardian or custodian in previous appearances before the Division.
D.C. S.C.R.-Neglect 20(b). In practice, counsel are appointed to represent indigent parents from a list of lawyers who, during the previous month, have requested assignments of juvenile delinquency cases for which compensation is provided under the District of Columbia’s Criminal Justice Act (CJA).6 This list is maintained by the D.C. Public Defender Service.
When an attorney registers for compensated CJA work in the Family Division, he is notified that he may be appointed to neglect cases on a pro bono publico basis. Affidavit of W. Anthony Fitch, Deputy Director of the Public Defender Service for the District of Columbia (Oct. 20, 1982). The Public Defender Service and the judges of the superior court repeatedly warn attorneys that they will not be appointed to CJA-compensated cases if they do not also agree to represent indigent parents in neglect proceedings.
B. The Superior Court Proceeding
David Sitomer, an individual attorney-appellant in this case, as the appointed attorney for parents in two neglect proceedings, filed a motion in superior court seeking administrative relief and compensation for services. He alleged that his uncompensated appointment as parents’ counsel in many neglect proceedings was confiscatory and an unconstitutional “taking” of his property without just compensation. See In the Matters of N.P. and L.W., Nos. 404-79, 418-79 (D.C.Super.Ct. June 14, 1982). Superior Court Judge Block ordered Sitomer to present evidence on how the appointment system in neglect cases actually worked and what its effect on appointed lawyers was. Judge Block also denied petitions to intervene in the proceeding filed by thirteen other lawyers, including the two individual appellants in this case, and by Sitomer in his capacity as President of the Family Division Trial Lawyers Association. Addressing Sitomer’s individual claim, the court concluded that “it simply cannot be said that Mr. Sitomer’s neglect caseload was so excessively burdensome that he was compelled to foresake his regular law practice. Likewise the evidence relating more generally to the practices of the Family Division does not reveal a system so noxious as to violate Mr. Sitomer’s constitutional rights.” Id. at 3-4. Although Judge Block found no violation of Sitomer’s constitutional rights, he did find the practice by which counsel for parties in neglect cases is appointed was inadequate and unfair in several respects:
While it is obvious that this practice has been bureaucratically expedient, it is just as clear that it has insured neither the delivery of the appropriate level of representation to all parties in neglect actions nor equitably distributed the burdens of pro bono representations among those attorneys who practice before the Family Division. Accordingly, the neglect appointment list should be expanded beyond its present scope.
Id. at 5.
Initially, Sitomer appealed the superior court decision denying him relief, but later voluntarily abandoned that appeal claiming he could not afford a transcript and other costs of the appeal. The other appellants [700]*700appealed the district court’s denial of intervention but they too abandoned their appeals claiming insufficient funds to cover court costs. See Order Dismissing Appeals, In re N.P., Jr., No. 82-908 (D.C.Ct.App. Aug. 14, 1983); Motion to Withdraw Appeal, In re N.P., Jr., No. 82-908 (D.C.Ct. App. June 15, 1983).
C. The District Court Decision
Before moving to withdraw their appeals in the D.C. Court of Appeals, Sitomer and the other lawyers, along with the Family Division Trial Lawyers Association, filed a new complaint in federal district court alleging that the practices by which the superior court assigns counsel to represent parents in neglect proceedings constitutes involuntary servitude and a “taking” of property without just compensation because it requires attorneys to work for nothing. They also claimed that placing the burden of representing indigent parents exclusively on Family Division attorneys who depend on CJA-compensated cases rather than spreading it among other D.C. bar members or even other non-Family Division CJA-compensated attorneys amounts to so disproportionate a burden as, to constitute a “taking” as well as a denial of equal protection of the law, in violation of the fifth amendment. The appellants seek damages for past financial losses for uncompensated appointments and an injunction against further inadequately compensated appointments.
The district court dismissed the thirteenth amendment and “taking” claims stating, first, that compelled public service is not, in and of itself, involuntary servitude, even when imposed on a limited segment of the population. Specifically, requiring attorneys to take pro bono cases is neither involuntary servitude nor a per se “taking.”
The district court acknowledged, however, that if a system of compulsory assignments without pay sufficiently burdened individual attorneys so that their ability to earn a livelihood was endangered, it could constitute a prohibitive “taking” of property. The court, however, noted that Local Rule l-9(h) allows a court to “assume that the facts as claimed by the moving party in his statement of material facts are admitted to exist except as and to the extent that such facts are controverted in a statement filed in opposition to the motion.” D.D.C.Civ.R. l-9(h). Because the appellants filed no specific refutation of the material facts cited in the appellees’ motion for summary judgment — that “neglect cases do not usually require substantial ... efforts,” and “the burden placed on an attorney by neglect appointments does not impair the attorney’s ability to engage in remunerative practice” — and because the appellants’ cross-motion for summary judgment, filed in lieu of the opposition required by Rule l-9(h), did not specifically allege that the superior court appointment system unduly burdened them, the district court granted the appellees’ motion for summary judgment on the “taking” issue. See Family Division Trial Lawyers of the Superior Court of the District of Columbia, Inc. v. Moultrie, No. 82-1373, slip op. at 7-8 (Dec. 20, 1982).
Finally, the district court held that the appellants’ complaint did not state a claim for violation of the equal protection clause. It reasoned that “it is entirely rational to select lawyers who have expressed an interest in Family Division appointments to take on neglect cases; lawyers who request appointment to Family Division actions may be presumed to be more experienced in family legal issues and therefore may be presumed capable of providing more skilled counsel.” Id. at 10.
II. Abstention
In addition to their argument that the grant of summary judgment in their favor was correct, the appellees also maintain that the district court should have abstained from deciding the merits of the appellants’ claims at all. The appellees say that any federal court decision in this case directly interferes with and undermines local judicial proceedings involving important “state” interests in which the appellants’ [701]*701constitutional claims could have been raised and adequately dealt with. They argue that the progeny of Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971), applying its principle of equitable abstention by federal courts to civil as well as criminal proceedings in state courts, should control here.7 We agree, in the main, with appellees’ position that in the great majority of cases local courts should be free to follow their own schemes of judicial administration, unfettered by directives from the federal courts. However, local judicial administration is not immune from attacks in federal court on the ground that some of its practices violate federal constitutional rights. See District of Columbia Court of Appeals v. Feldman, — U.S. —, 103 S.Ct. 1303, 75 L.Ed.2d 206 (1983) (claim that D.C. bar admission requirement that applicants graduate from an accredited law school is unconstitutional presents a federal question). In this case, we find that the Younger abstention doctrine, developed to prevent undue federal court interference in local judicial administration, does not apply to bar the district court’s consideration of the appellants’ constitutional challenges.
Younger held that a federal court should abstain from entertaining suits raising constitutional issues if the federal plaintiff is a defendant in a pending state criminal proceeding and the defendant can raise those issues in state court as defenses to his prosecution. Federalism and comity lie behind Younger: federal courts should respect state courts’ abilities to adjudicate federal constitutional rights where adjudication of those rights will arise normally in the course of the pending state court proceeding. See Trainor v. Hernandez, 431 U.S. 434, 441, 97 S.Ct. 1911, 1916, 52 L.Ed.2d 486 (1977). Permitting federal courts to entertain separate.suits involving these federal claims while the state action is pending would not only result in duplicative legal proceedings but might produce the uncomfortable spectacle of federal injunctions prohibiting a state from enforcing its own criminal law or the decisions that emanate from its own state courts. See Huffman v. Pursue, Ltd., 420 U.S. 592, 602-03, 95 S.Ct. 1200, 1207-08, 43 L.Ed.2d 482 (1975) (citing Steffel v. Thompson, 415 U.S. 452, 462, 94 S.Ct. 1209, 1217, 39 L.Ed.2d 505 (1974)); Kaplan v. Hess, 694 F.2d 847, 851 (D.C.Cir. 1982). The only justification for federal court interference during a state proceeding would be a premise that the state courts cannot be trusted to adequately protect federal constitutional rights, a premise unequivocally rejected by the Younger Court. See Middlesex County Ethics Committee v. Garden State Bar Assoc., 457 U.S. 423, 431, 102 S.Ct. 2515, 2521, 73 L.Ed.2d 116 (1982); Kaplan, 694 F.2d at 851.
Since its promulgation, the Younger doctrine has been extended beyond criminal proceedings to cover pending civil actions in state courts. It is noteworthy, however, that virtually all post- Younger cases have involved collateral attacks in federal court on state enforcement proceedings brought against the federal plaintiff.8 Thus, Huffman, 420 U.S. 592, 95 S.Ct. 1200, upon which the appellees heavily rely, involved an attack in federal courts on the constitution[702]*702ality of a state nuisance statute used to shut down theatres showing obscene movies, where the state had already brought an action under that statute to close the theatres. Similarly, Juidice v. Vail, 430 U.S. 327, 97 S.Ct. 1211, 51 L.Ed.2d 376 (1977), involved a collateral attack on the constitutionality of civil contempt proceedings brought by the state against judgment debtors who disobeyed subpoenas. See also Trainor v. Hernandez, 431 U.S. 434, 97 S.Ct. 1911, 52 L.Ed.2d 486 (refusing to decide the constitutionality of a state attachment proceeding brought to recover money from public assistance recipients who allegedly concealed assets).
There is good reason why the Younger abstention policy is best suited to cases where federal plaintiffs are trying to attack state enforcement procedures which have been directly applied to them. For, in such cases, the state has brought the federal plaintiffs before its own courts to protect important policy and resource interests and in such cases the plaintiffs’ federal action are perceived as attempts to divert or circumvent state court adjudication. The need or wisdom of extending Younger to all constitutional claims that might be adjudicated in state as well as federal courts, however, is far more problematical. This extension would make federal courts cin-derellas to their sister state courts in adjudicating federal constitutional rights, their native area of competence and jurisdiction. And it would prevent plaintiffs from exercising their traditional choice of bringing constitutional claims in either forum, even where there is no strong state interest in how or where the claims are decided. See Steffel v. Thompson, 415 U.S. at 462-63, 94 S.Ct. at 1217-18; Monroe v. Pape, 365 U.S. 167, 183, 81 S.Ct. 473, 481, 5 L.Ed.2d 492 (1961).
Moore v. Sims, 442 U.S. 415, 99 S.Ct. 2371, 60 L.Ed.2d 994 (1979), represents the outer limit to which the Supreme Court has extended Younger abstention. Moore held that a federal court should not entertain a parent’s constitutional challenge to the state practice of removing suspected child abuse victims from parental custody without notice pending a hearing on the abuse charge. While the parent’s challenge to the interim removal procedure was not technically a defense to any charge of child abuse, the temporary removal policies were inextricably tied up with the state interest in protection of its children, the very raison d’etre for the abuse proceedings. See Moore, 442 U.S. at 430 n. 12, 99 S.Ct. at 2380 n. 12 (claiming that hinging abstention doctrine on whether federal issue is a “defense” to state proceeding is a mere “semantic joust”). And, there was no question the parents could raise the constitutional issue in the course of their abuse proceedings.
This case falls outside the Moore perimeters, and hence we find abstention to be inappropriate. Except for Sitomer, the plaintiff-appellants were not parties to any pending suit in the local courts in which their constitutional challenges could naturally be resolved.9 The District has brought no proceedings against any of these appellants. This alone distinguishes the case from the reach of Younger situations. See, e.g., Kaplan v. Hess, 694 F.2d at 851 (Younger not applicable because no pending proceeding in case where appellants challenged a local court rule requiring them to stand when judges enter or leave the courtroom); New Jersey-Philadelphia Presbytery of the Bible Presbyterian Church v. New [703]*703Jersey State Board of Higher Education, 654 F.2d 868 (3d Cir.1981) (Younger did not bar non-parties to state enforcement proceedings against unlicensed college’s operation from bringing federal suit to enjoin state from continuing enforcement efforts); see also Doran v. Salem Inn, Inc., 422 U.S. 922, 95 S.Ct. 2561, 45 L.Ed.2d 648 (1975) (plaintiffs who refrained from criminal activity — employing topless dancers — are not barred by Younger from bringing a federal challenge to the criminal statute, although other plaintiffs who committed the crime, and who were represented by common counsel, with similar business activities and problems were barred by pending state criminal proceedings). In addition, the individual neglect cases in which the appellants are counsel are questionable vehicles at best for raising their constitutional claims. The local court here has already said so when it denied intervention by other attorneys in Sitomer’s proceeding. It noted:
By their very nature neglect proceedings contemplate issues centering on the care of a child by his or her parent. If need be “related matters involving the same family or household” can be consolidated. SCR-Neglect 2 & 3(b). Anything broader is inconsistent with the nature of the proceedings.
Mr. Sitomer’s claims touched on issues affecting his representation of parties in the above-captioned cases, but intervention by other attorneys would completely separate the cases from their roots in the original complaints of neglect. In this instance we have already strained the bounds of the neglect proceeding and we cannot allow it to bear the burden of what would amount to an informal class action. Moreover, the Court notes that, in fact, a class action suit has been filed recently in U.S. District Court. That suit will surely provide a better forum for presenting the claims of the attorneys than can be obtained by any bootstrapping efforts here.
In the Matters of N.P. and L.W., slip op. at 2-3 (emphasis supplied). Consistent with the superior court’s reasoning, we find that Younger does not apply to bar claims that are so ancillary to arguably related local court proceedings that even the local court finds the claims disruptive of the resolution of core issues in those proceedings.
Appellees additionally contend that any relief for the appellants would require the federal courts to interfere in the superior court administration of appointment of counsel in neglect cases. Therefore, even if Younger abstention is technically inappo-site, the district court should stay its hand in this case under the principle discussed in O’Shea v. Littleton, 414 U.S. 488, 94 S.Ct. 669, 38 L.Ed.2d 674 (1974), that a federal district court should not consider a claim where granting the prayer for relief would require the federal court to monitor day-today operations of the local courts.
This case, however, is very different from O’Shea. There, the plaintiffs — citizens of Cairo, Illinois, who organized and participated in an economic boycott of merchants purportedly engaged in racial discrimination — alleged a pattern and practice of racial discrimination in discretionary judicial conduct, including sentencing and setting bail, by a state judge and magistrate. The Court held that the plaintiffs had no standing to sue for injunctive relief since their claim asked the Court to presume future constitutional violations against them by state judicial officers. In addition the Court stated that any injunctive relief would violate the rationale of Younger since it would require federal courts to monitor the day-to-day operation of state judicial proceedings. Id. at 501-02, 94 S.Ct. at 678-79. The federal court would have had to directly review the state judge’s and magistrate’s decisions to see if they abused their discretion whenever they sentenced one of the plaintiffs, or set bail in a case involving a plaintiff. In this case, the appellants challenge a non-discretionary method of appointing uncompensated counsel because that method allegedly confiscates their opportunity to practice law. Although the challenged method is established by neither statute nor written rule, it indisputably operates more like a rule, a custom or a usage known to all participants in the [704]*704system, than a decision left to the local judiciary’s discretion to be exercised on a case-by-case basis. It follows that if the rule is adjudicated to be unconstitutional, relief can be effected by requiring the superior court to adopt another “rule” which more equitably divides the financial burdens attendant to provision of counsel for indigent parents in neglect proceedings. There is no foreseeable need for any “monitoring” of its day-to-day operations. So, even if the O’Shea “monitoring” rationale were sufficient by itself to justify abstention, it would not apply here.
In sum, we are not unmindful of the District’s stance that it has an important local interest in its neglect proceedings, cf. Moore, 442 U.S. at 428, 99 S.Ct. at 2377 and that attorney-assignment practices initiated and administered by its judiciary play an important role in its scheme to enforce its neglect laws. But, that interest standing in isolation is not sufficient to block a federal court from considering a claim that the practices operate in an unconstitutional manner to burden unduly or unfairly a small segment of the bar. See Feldman, 103 S.Ct. at 1316. In considering the merits of appellants’ claims we see no potential for duplicative litigation, nor for irreverence toward the local courts, and no necessity that relief need interfere with the day-today operation of the superior court. Like the district court, we find abstention inappropriate in this case.
III. Sitomer’s Claims
We turn now to the merits of the summary judgment decision by the district court. We consider Sitomer’s claims first. Sitomer has already brought and lost an action in superior court which adjudged on the merits several of the issues raised in this case. That court found that Sitomer suffered no constitutional injury prior to filing this suit. Hence, his claim for damages due to allegations that these past appointments abridged his constitutional rights is barred by res judicata. See Kremer v. Chemical Construction Corp., 456 U.S. 461, 102 S.Ct. 1883, 72 L.Ed.2d 262 (1982); cf. Allen v. McCurry, 449 U.S. 90, 101 S.Ct. 411, 66 L.Ed.2d 308 (1980) (applying collateral estoppel).
Whether res judicata also bars Sitomer’s broader claims that the system is so unfair it inherently infringes on his constitutional rights, and therefore that he should receive no future neglect appointments, is a tougher question. While we might hesitate to invoke res judicata to bar Sitomer from litigating claims about future appointments that he could have brought but did not,10 here the superior court judge actually entertained and rejected such claims. It found that the appointment practices of the Family Division are not generally “so noxious as to violate Mr. Sitomer’s constitutional rights.”11 See In the Matters of N.P. and L.W., slip op. at 4. Therefore, we hold that all of Sitomer’s claims are barred by res judicata.
IV. Constitutional Claims
A. The Thirteenth Amendment
The other appellants seek to invalidate under the thirteenth amendment judicial appointments of counsel to represent parties where neither the parties nor the state adequately compensate the appointed attorneys for their services.12 The [705]*705system by which the superior court appoints counsel to represent indigent parents, however, is not forced labor. An attorney who wishes to take no further assignments is free to either stop practicing before the Family Division, or even to continue to practice without taking CJA-compensated juvenile cases. Inability to avoid continued service is the essential ingredient of involuntary servitude. See Flood v. Kuhn, 443 F.2d 264 (2d Cir.1971), aff'g 316 F.Supp. 271 (S.D.N.Y.1970), aff’d on other grounds, 407 U.S. 258, 92 S.Ct. 2099, 32 L.Ed.2d 728 (1972); Wicks v. Southern Pacific Co., 231 F.2d 130, 138 (9th Cir.1956), cert. denied, 351 U.S. 946, 76 S.Ct. 845, 100 L.Ed. 1471 (1956). Since the superior court appointment system lacks this ingredient, we agree with the district court that the appellants’ complaint fails to raise a genuine thirteenth amendment issue.
B. “Taking” of Property Without Just Compensation
The district court also rejected appellants’ constitutional claim that requiring an attorney to perform traditional pro bono service amounts to a “taking” of property. The leading case, United States v. Dillon, 346 F.2d 633 (9th Cir.1965), cert. denied, 382 U.S. 978, 86 S.Ct. 550, 15 L.Ed.2d 469 which the district court cited, makes clear the rationale behind the traditional service exception:
The obligation of the legal profession to serve indigents on court order is an ancient and established tradition, and ... appointed counsel have generally been compensated, if at all, only by statutory fees which would be inadequate under just compensation principles, and which are usually payable only in limited types of cases. Further, ... the vast majority of the courts which have passed on the question have denied claims of appointed counsel for nonstatutory just compensation, pointing out that representation of indigents under court order, without a fee, is a condition under which lawyers are licensed to practice as officers of the court, and that the obligation of the legal profession to serve without compensation has been modified only by statute. An applicant for admission to practice law may justly be deemed to be aware of the traditions of the profession which he is joining, and to know that one of these traditions is that a lawyer is an officer of the court obligated to represent indigents for little or no compensation upon court order. Thus, the lawyer has consented to, and assumed, this obligation and when he is called upon to fulfill it, he cannot contend that it is a “taking of his services.”
Id. at 635; see also DeRodulfa v. United States, 461 F.2d 1240, 1256 (D.C.Cir.1972) (dicta), cert. denied, 409 U.S. 949, 93 S.Ct. 270, 34 L.Ed.2d 220; Williamson v. Vardeman, 674 F.2d 1211, 1214 (8th Cir.1982); White v. United States Pipe & Foundry Co., 646 F.2d 203, 205 & n. 3 (5th Cir. Unit B 1981). In this case, the argument that pro bono appointments are not per se “takings” is bolstered by the repeated emphasis by the D.C. Public Defender Service and the superior court that CJA-compensated appointments open the appointed attorneys to the possibility of assignment of cases for no pay. Hence, appellants cannot now maintain that they had an expectation rising to the level of a property right that they would be compensated for their services. Although appellants do make a token claim that any uncompensated service required would be unconstitutional, we do not subscribe to such a position. Thus, there is no facial unconstitutionality to the statute or rules that require appointments in uncompensated cases.
While we agree with the district court that some pro bono requirements do not constitute a “taking,” we think it equally clear that an unreasonable amount of required uncompensated service might so qualify. As the scope of the constitutionally mandated right to counsel has expanded, and the concomitant burden of providing pro bono representation imposed on attorneys has grown, several state courts have [706]*706recognized that at some point the burden on particular attorneys could become so excessive that it might rise to the level of a “taking” of property. See, e.g., People ex rel. Conn. v. Randolph, 35 Ill.2d 24, 219 N.E.2d 337 (1966); Bias v. State, 568 P.2d 1269 (Okla.1977); State ex rel. Partain v. Oakley, 227 S.E.2d 314 (W.Va.1976); cf. Menin v. Menin, 79 Misc.2d 285, 359 N.Y.S.2d 721 (Sup.Ct.1974) (appointment of counsel in civil case not mandated since such appointment would abridge appointed attorneys’ property rights). And, although the appellants here have no expectation of compensation for their services in appointed cases that rises to the level of a property interest, “the right to conduct a business and enter a profession is considered a property right within the meaning of various constitutional provisions.” Menin, 359 N.Y.S.2d at 729; see also Board of Regents v. Roth, 408 U.S. 564, 574, 92 S.Ct. 2701, 2707, 33 L.Ed.2d 548 (1972) (if state denied terminated professor opportunity for all other public employment in state university, that might violate due process clause); Schware v. Board of Bar Examiners, 353 U.S. 232, 77 S.Ct. 752, 1 L.Ed.2d 796 (1957) (due process applies to bar licensing, since that is state’s grant of permission to engage in the occupation of lawyer); Joint Anti Fascist Refugee Committee v. McGrath, 341 U.S. 123, 185, 71 S.Ct. 624, 655, 95 L.Ed. 817 (1951) (due process applies to denials of opportunity for future government employment). Thus, while the District may enact regulations that affect property interests, where those regulations unreasonably “frustrate distinct investment-backed expectations” they may “amount to a ‘taking.’ ” Penn Central Transportation Co. v. City of New York, 438 U.S. 104, 127, 98 S.Ct. 2646, 2660, 57 L.Ed.2d 631 (1978) (citing Pennsylvania Coal Co. v. Mahon, 260 U.S. 393, 43 S.Ct. 158, 67 L.Ed. 322 (1922)). In short, if the superior court appointment system effectively denies the appellants the opportunity to maintain a remunerative practice as family lawyers before the Family Division, and that specialty practice is determined to be a “property” interest, it might effect an unconstitutional “taking.”13
The dissent and appellees argue that “as a matter of law ... no level of burdensomeness could rise to the level of a taking as long as appellants have volun[707]*707teered their services.” Diss.Op. at 713; see also Brief for Appellees at 22-27. The dissent is anchored in the circumstance that “only by their voluntarily seeking compensated cases were they [the Family Division lawyers] then required to take on uncompensated cases.” Diss.Op. at 713. Although proving a “taking” in a situation like this one is obviously a formidable task, we are not willing at this point to rule it out as a matter of law. A “taking” might occur if the following crucial findings were made: First, the attorneys’ expectations of pursuing the specialty practice of family law would have to be shown to be sufficiently established within the norms and traditions of legal practice to constitute a property interest. The dissent takes umbrage at the notion that a protected interest in a specialty practice could ever be legally recognized, although it admits that the practice of law generally might so qualify. See Diss.Op. at 714. We fail to see any inherent reason why the practice of law is protected by the takings clause but the practice of a legal specialty could never be protected. Surely, for instance, it is at best questionable whether the District could declare that henceforth all lawyers practicing before the Family Division may not accept any fees or compensation at all. We rule today only that the existence of a property interest in such practice is a matter calling for material factual development and argument in the district court, not one to be decided by appellate fiat in the absence of any record whatsoever. Second, the number of Family Division cases where the parties can pay for their own counsel would have to be limited enough so that withdrawing from the market of government compensated cases would effectively be a decision to withdraw altogether from practice before the Family Division,14 contrary to the appellees’ and dissent’s suggestion that the appellants would be “free to decide whether to conform to the proposed specifications or withdraw from the government market.” See Brief for Appellees at 23 (quoting Control Data Corp. v. Baldridge, 655 F.2d 283, 293 (D.C.Cir.1981)); see also Diss.Op. at 713. Finally, the assignment of uncompensated neglect cases attached to “volunteering” for CJA-compensated cases would have to be so burdensome that it effectively denies the appellants’ ability to earn a living by practicing family law. The record is obviously not sufficiently developed at this point to allow such findings either to be made or entirely discounted.
The district court ruled for the appellees because it found that the appellants never alleged that the appointment system was sufficiently burdensome to prevent them from engaging in a remunerative practice. It did acknowledge that if the burden the neglect appointments imposed on the appellants was heavy enough their constitutional claims might be valid, but it relied on the appellees’ assertions in their Statement of Material Facts that “neglect cases do not usually require substantial research and investigation and most of the time is waiting time attributed to paying CJA cases,” Family Division Trial Lawyers, slip op. at 7-8, to support its factual conclusion underlying summary judgment, that the burden “does not impair the attorney’s ability to engage in remunerative practice.” Id. Our reading of the record, however, does not support the district court’s conclusion that the linchpin fact of nonimpairment was not truly in contest.
The district court relied for that critical finding on the lack of a formal contravention to the appellees’ Statement of Material Facts, as required by Rule 1-9(h). The appellants’ failure, however, to file such a piece of paper is understandable, [708]*708in part at least, in view of the circumstance that the district court, sua sponte, ordered the parties to file cross-motions for summary judgment by a fixed date. Apparently, both parties assumed that the cross-motions would serve as a sufficient indication of what, if any, issues of material facts were still at issue.15 We are therefore reluctant to affirm a grant of summary judgment based on a key fact which we believe to have been at issue, but which the district court found to be uncontroverted on the technical ground that the appellants had not complied with Rule l-9(h), where there is evidence that both parties believed they were permitted to file only simultaneous cross-motions, not responsive pleadings.
It is true that the appellants’ own Statement of Material Facts did not specifically allege an unreasonable burden resulting from the assignment system, and that its formal motion for summary judgment repeated the boilerplate that there was no issue of material fact to be decided. We are also at a loss to understand why the appellants agreed at all to file cross-motions for summary judgment when the crux of their “taking” and equal protection claims hinged on the factual issue of how heavy a burden had been imposed on them. Nonetheless, in the final analysis, we cannot in good conscience square the district court’s finding that the appellants “nowhere controverted” the appellees’ assertion that the neglect appointment system did not impose an undue burden with the record of the case before us, particularly when the appellants’ Points and Authorities in Opposition to Defendants’ Motion for Summary Judgment spent most of its ten pages contesting that critical fact.16 Moreover, similar documents in the record reveal that the key fact of whether the Family Division Lawyers were unduly burdened was not only at the heart of this case, but was hotly contested from the start. See, e.g., Complaint at 7-8 (“the burden of representation has driven many attorneys to abandon juvenile practice”); Points and Authorities in Support of Plaintiffs’ Motion For Summary Judgment, at 7 (“[t]he burden for some lawyers is staggering”). No one reading these papers could come away with the impression that the appellants did not generally claim that the sheer number of nonpaying appointments was a great financial burden on them, or that if the burden was not perceived to be great, the case would have been brought in the first place.
But there is a more fundamental reason why we cannot accept the district court’s grant of summary judgment. The stakes in this case are too great not only for the lawyers and court personnel but also for the [709]*709parents and children involved in neglect cases to let stand a judgment mistakenly entered without any judicial inquiry upon “facts” — that representation of parents in neglect cases entails minimum time and effort and need exact no substantial premium in time or talent from legal advocates— which are widely perceived in the local bar and in the community at large, not to be true, and which have been the core of a decade-old controversy.17 Such a judicial affirmation made without an adequate inquiry into these facts’ truth or falsity would, we fear, invite disrespect of the courts and undermine the credibility of their procedures. As illustrative of the intensity and the high visibility of the controversy, we note a D.C. Bar report in which the present appointment system’s inability to guarantee adequate representation to parents or adequate compensation to assigned lawyers is highlighted.18 Since professional standards for adequate representation of parents in neglect and termination proceedings obviously require a great deal more than the token representation that the district court assumed neglect cases demand,19 we do not think it proper for us to dismiss a constitutional claim on the ground that such efforts are all that is called for from assigned counsel. Too much is at stake for too many.
In short, the district court based its dismissal of the “takings” claim specifically on a finding that the burden was not a heavy one; we remand for a more complete record on the precise extent of the burden as those services are currently performed and as they should be performed under adequate professional standards, as well as on the status of Family Division attorneys’ expectations of carrying on practice in the Division and their need to rely on government compensated cases to do so.
C. The Equal Protection Claim
The district court found that the decision to restrict pro bono appointments to lawyers hoping to receive CJA-compensated appointments was rational and it therefore dismissed this claim. We agree that the appellants’ right to earn a living as lawyers is not so fundamental that [710]*710it triggers strict judicial scrutiny of the challenged system; if the system reflects a rational choice aimed at furthering legitimate state interests, a court must uphold it. See Minnesota v. Clover Leaf Creamery Co., 449 U.S. 456, 461-64, 101 S.Ct. 715, 722-23, 66 L.Ed.2d 659 (1981); United States Railroad Retirement Board v. Fritz, 449 U.S. 166, 174-76, 101 S.Ct. 453, 459-60, 66 L.Ed.2d 368 (1980). We also agree that the district court properly identified the state interest furthered by the appointment system as the guarantee of adequate representation for children and parents in neglect proceedings. But, we cannot conclude, based on the factual record developed thus far, that the District’s choice to implement the system as it did — in particular its choice to restrict pro bono appointments to attorneys on the Public Defender Services list for CJA appointments in juvenile eases— was rational.
Arguments that the District acted rationally in presuming that lawyers who regularly practice before the Family Division are best able to represent parents in neglect proceedings, and in requiring more from recipients of the public fisc than from other attorneys, bring us no more than to the halfway mark in analyzing the appellants’ equal protection claim. At some point, even initially rationally motivated restrictions on the pool of attorneys assigned pro bono cases may result in such enormous demands on the time and energy of these appointed attorneys that they cease to be rational either in the results they engender of ineffective representation for indigent parents, or the burdens they impose on the chosen attorneys:20 For example, to require the one most experienced neglect lawyer in the local bar to take on all pro bono assignments would surely not survive even a rational means test. It is by no means clear from the sparse record before us whether this point has been reached or even approached. Since the constitutional claim at issue is the discriminatory application of the system, not just its design, further fact-finding is required.
We realize that since the appellants filed their complaint, the District has begun to pay small but not insignificant sums for representation of indigent parents in neglect proceedings.21 This new factor could alter any assessment of the effects of restricting the pool of attorneys who are assigned pro bono neglect cases. But, as with the “takings” issue, we remand for a more accurate assessment of the extent of the remaining burden on the appellants — to see if the classification meets the rational means test.
We emphasize that our remand is only to permit the district court to decide on a fuller record the constitutional issues involved in the application of the assigned counsel system — to elucidate the extent of the burden currently falling on family lawyer practitioners, as well as what that burden would be if they performed their chores in accordance with professional standards. Administration of the local court system is a province we enter hesitantly. We are all too aware of the financial dilemma that the local court system faces in trying to provide assigned counsel for indigent litigants. We assume a great deal of deference must be given to its attempts to keep the system afloat without violating the constitutional and statutory rights of children, parents, or lawyers. At this juncture, however, we feel compelled, as did the district court, to entertain the constitutional claims of the allegedly aggrieved lawyers. Right now, we merely require that a first cut on their claims be made on an adequate record. In the event that any of those claims are upheld, we expect much deference by the district court and much participation by the [711]*711local judiciary in formulating an equitable remedy.
Conclusion
For the reasons set out above, we reverse the decision of the district court in part, affirm it in part, and remand this case for further proceedings.
It is so ordered.
