Opinion for the Court filed by Circuit Judge HARRY T. EDWARDS.
Separate Statement, concurring in part and dissenting in part, filed by Circuit Judge BORK.
At issue in this case is the validity of one aspect of the administration of the federal Witness Protection Program.1 Exercising the discretion vested in them by statute, various federal officials relocated and changed the identities of a government informant, his wife, and her three children by a former marriage, in return for the informant’s testimony against alleged leaders of organized crime. Unfortunately, this routine and otherwise unassailable procedure had the effect of severing the ongoing relationship between the children and their natural father. The father brought the present suit — on behalf of himself and his children2 — challenging the actions of the federal officials on a variety of constitutional and statutory grounds. He sought declaratory and injunctive relief to enable him to reestablish contact with his children, and damages to compensate all of them for injuries sustained as a result of their separation. The District Court dismissed the complaint for failure to state a claim upon which relief can be granted.3
As all parties concede, resolution of this case requires a weighing of three important interests: the public interest in the suppression of organized crime; the interest of the informant, his spouse, and the children in securing protection against the threat of violent reprisal to which they are all exposed; and the interest of the children and their father in maintaining the bonds between them. The essence of the plaintiffs’ claims is that, in acting to sever totally and permanently the relationships between a non-custodial parent and his minor children without their participation or consent, the defendants struck an impermissible balance of the foregoing interests. Although we reach no judgment on the proper *389ultimate disposition of this case, we conclude that the plaintiffs clearly have stated a cause of action sufficient to survive a motion to dismiss.
Taking as true the facts alleged in the complaint,4 we find that the administrators of the Witness Protection Program abrogated the constitutionally protected rights of the plaintiffs to one another’s companionship without (1) affording the father requisite procedural protections, (2) making a particularized finding and showing of a legitimate state interest sufficient to justify the infringement, or (3) availing themselves of equally effective alternative solutions to the problem before them that would have been less restrictive of the plaintiffs’ rights. Accordingly, we reverse and remand for further proceedings.5
I. Background
A.
The Witness Protection Program was established as part of the Organized Crime Control Act of 1970.6 Its purposes are to guarantee the safety of government witnesses who agree to testify against alleged participants in organized criminal activity and thereby to create an incentive for persons involved in such activities to become informants. Broad discretion is vested in the Attorney General “to provide for the security of” such witnesses.7
It was originally contemplated that the program would be implemented principally through the purchase and maintenance of housing facilities that would serve as more or less permanent havens for witnesses and *390their families.8 That approach soon proved impracticable and the strategy was adopted of relocating witnesses and their families and providing them with “new identities, the documents to support these new identities, as well as housing, employment, medical services and other social services.”9
The Attorney General has delegated to the United States Marshals Service virtually all of his authority over the actual administration of the program.10 But decisions regarding who will be accepted into the program are still made by certain direct subordinates of the Attorney General. An Order promulgated by the Justice Department in 1975 provides that a recommendation to admit a prospective witness must be made by a U.S. Attorney or Assistant U.S. Attorney and approved by the Assistant Attorney General in charge of the concerned division.11 Only after this screening process has been completed is the Marshals Service notified and instructed to prepare for the induction of the witness.12
The Justice Department Order also prescribes criteria by which prospective inductees are to be evaluated. The Assistant Attorney General is instructed to admit a “proposed witness” into the program only upon satisfaction of the following conditions:
(1) The person is a qualifying witness in a specific case in process or during or after a grand jury proceeding,
(2) Evidence in possession indicates that the life of the witness and/or that of a member of the witness’ family or household is in immediate jeopardy, and
(3) Evidence in possession indicates it would be advantageous to the Federal interest for the Department to protect the witness and/or a family or household member.13
These criteria, it will be observed, make no mention of the impact of the admission of a witness and his “family or household” on established relationships between members of that household and other persons (e.g., natural parents); the Assistant Attorney General is to consider only the advantage to the “Federal interest” of accepting each candidate, not the effects upon the interests of third parties.14
*391Nor does it appear that peripheral familial rights are taken into account at any other point in the standard admission procedure or in the subsequent administration of a case. The one apparent (and partial) exception to this generalization turns out, in practice, to be illusory. At the time of their induction, all witnesses and adult members of their households are required to read and sign a lengthy “Memorandum of Understanding.” 15 The document includes the following provisions: a warning by the Marshals Service that it “WILL NOT SHIELD witnesses from civil or criminal litigation initiated prior to or subsequent to entry into the Program”;16 a mandate that “[a]ll court orders which are directed to the witness must be immediately brought to the attention of the ... Marshals Service” (combined with a strong suggestion that the Service will assist in their enforcement);17 and a form authorizing either the Marshals Service or a named party to receive service of process on behalf of the witness.18 These provisions might be interpreted as requirements that participants in the program abide by judicially ratified familial rights of third parties. Indeed, a former Director of the Marshals Service testified in 1978 that it was the current “policy” of the Service to “work to secure some accommodations so the rights of [a non-relocated parent] are protected” — specifically, to “maké [the children] available [for visitation] if the circumstances are proper.”19 However, such a “policy” certainly was not implemented in this case.20 And the defendants did not suggest, either in their brief or at oral argument, that the Service makes any affirmative effort to afford non-custodial parents access to their relocated children.21 We are compelled to conclude, therefore, that the character and strength of familial relationships between members of a witness’ household and third parties who will not be relocated are given no formal consideration either by the Justice Department officials responsible for deciding whether to admit a candidate and his “family or household” into the Witness Protection Program or by the administrators of the Marshals Service when deciding how any given case should be handled.
B.
Partly because of the preliminary stage at which the suit was dismissed, the circumstances out of which this action grows are not entirely clear. The following is a rough outline of the pertinent facts, assuming all allegations in the plaintiffs’ complaint are true.
In 1966, William Franz married Catherine Mary Franz. In the ensuing years, the couple had three children: William Michael Franz, Christine Catherine Franz, and Donna Marie Franz. Sometime thereafter the *392couple separated. In February 1974, a Pennsylvania court awarded William visitation rights; Catherine appears to have had or been awarded custody of the children.22 Between 1974 and 1978, William regularly exercised his right to visit his offspring.23 On July 9, 1976, William and Catherine were divorced.
Sometime prior to the divorce, Catherine “developed a personal relationship” with (and later may have married) one Charles Allen.24 Allen subsequently confessed himself to be a contract killer in the employ of leaders of organized crime in the Philadelphia area. He offered to testify in a federal criminal trial in return for the relocation and protection of himself, Catherine, and Catherine's three children. The Assistant Attorney General of the Criminal Division of the Department of Justice approved the arrangement, and in February 1978, Allen and the members of his household were accepted into the Witness Protection Program.25 We assume that Allen and Catherine read and signed a copy of the Memorandum of Understanding described above.26 On February 12, the Marshals Service transported Allen, Catherine, and the children from Sewell, New Jersey to an undisclosed location and provided them with new identities.
Since that date, William has been attempting, in a variety of ways, to determine the whereabouts of or to establish contact with his three children. He has repeatedly requested information from the Marshals Service. He has written his former wife (care of the Marshals Service) pleading his case. And, most recently, he has initiated litigation.27
*393The administrators of the program have not been wholly unresponsive. They have, by their own account at least, delivered William’s letters to Catherine. But they appear not to have put any pressure on either Allen or Catherine to reveal to William the location of the children or otherwise to accommodate William’s desires. And they have not attempted to devise any system for reconciling the conflicting interests of the affected parties. Officials of the Marshals Service acknowledge that they are capable of arranging meetings between William and his children without endangering Allen, Catherine, or the children,28 but they refuse to establish such contacts without her consent.
II. State Action
Before turning to the assessment of the plaintiffs’ various claims of constitutional violation, we must resolve a threshold question. The defendants argue that, however unfortunate the plaintiffs’ injuries, they are not legally responsible for those harms. The defendants point out that it is Catherine who has decided to deny William access to his children. The defendants also insist that they have done nothing more than decline to compel her to behave otherwise. For two reasons, they contend, such inaction cannot expose them to liability under the Constitution. First, they claim they lack the authority to do otherwise; they have no power, in other words, to force Catherine to accede to visitation of the children by William. Second, they argue that, even if they had such authority, their refusal to exercise it would not be a sufficiently affirmative or efficacious act to make them responsible for the consequences of Catherine’s behavior.
The defendants’ first argument gives us little pause. Whatever may be the legal or equitable limits on the defendants’ coercive authority, arising out of the terms of the Memorandum of Understanding or other agreements entered into by the Marshals Service and Allen and Catherine,29 the defendants clearly had the authority, at the time they consented to the admission of Allen and his household, to insist that the inductees agree to accommodate in some way the rights of William and the rights of the children to see their natural father. The Memorandum of Understanding contains several structurally similar provisions. The admittees undertook, for example, to stay away from the “danger area” unless they had the permission and protection of the Service30 and to permit the Service (or a designated substitute) to accept service of *394process on their behalf.31 The sanction for violation of these and other clauses is “termination” from the program. Those provisions are undoubtedly valid and enforceable; the discretion vested in the Attorney General by statute32 is broad enough to enable him or his representative to insist upon obedience to such terms as a condition of admission into and continuation in the program. In short, the defendants plainly cannot absolve themselves of responsibility on the ground that they have no authority to do what the plaintiffs demand.
The defendants’ second contention, albeit also without merit, warrants a somewhat more extended response. To evaluate it, we must venture into a sometimes obscure area of constitutional law: the doctrine relating to the degree to which a private party’s behavior must be instigated by or dependent upon the exercise of governmental authority to justify attribution of the consequences of that behavior to “state action.”33 Decisions involving this issue tend to turn upon nuances in the peculiar “facts and circumstances” of the case at hand34 and, thus, often are unusually difficult. Fortunately, the present suit does not present especially troublesome questions. Viewed from any of a number of perspectives, the conduct of the defendant officials is seen to be sufficient to establish a constitutionally significant link between the government and the alleged infringement of the plaintiffs’ rights.35
It is clear that the defendants, by accepting Catherine and the children into the program along with Allen, are largely responsible for the success of Catherine’s effort to deny William access to his offspring. Without the aid of the administrators of the program in providing her with a new identity, Catherine almost certainly would not have been able to frustrate William’s attempts to exercise and enforce his visitation *395rights; with that aid, she has been able to act with impunity. Such a potent contribution to the ability of one private party to infringe the legal interests of another by itself might be sufficient to give rise to “state action.”36
But there is more: this is not a case in which the government has merely provided general financial or other aid to a private party, without which he would have been unable to act as he did; rather, there is a close “nexus” between the content of the government’s aid and the specific behavior that is challenged in the suit.37 The nexus is formed principally by the defendants’ encouragement and support of Catherine’s decision to hide the children from William.38 To some extent, such encouragement is embodied in the terms of the Memorandum of Understanding by which Allen and his household were informed of the nature of the program. Thus, signatories are obliged to “acknowledge[ ] the necessity to terminate correspondence, where possible, with persons known prior to entry into the Witness Security Program for reasons of security”39 and generally not to act in any way that might “jeopardize[ ] the witness’ security”;40 such undertakings may well have made Catherine more reluctant than she otherwise would have been to keep open the channels of communication with her former husband.41 But more importantly, encouragement of the challenged behavior inevitably has been generated by the structure of the program. The defendants have placed Catherine in a position where any effort by her to accommodate William’s and the children’s reciprocal rights — at least *396in the absence of active assistance by the Marshals Service in ensuring the secrecy and security of contacts — may well endanger the lives of her spouse, her children and herself.42 It is hard to imagine a more powerful kind of impetus.
There is yet a third theory upon which a finding of “state action” may be based. This case involves a situation in which the plaintiffs’ claims are founded in significant part upon state law governing family relationships. In particular, William asserts certain rights under Pennsylvania law to maintain contact and visitation with his minor children. See note 22 supra. Catherine clearly had no power or authority under applicable state law to enter into an arrangement with another private party to modify or vitiate the rights of William and her children to maintain their relationship. Thus, when Catherine entered the Witness Protection Program, pursuant to an agreement with the defendants, she accomplished something that was not otherwise legally achievable absent the formal intervention of the federal government. Thus viewed, this is a classic case of “government action,” where a “federal statute is the source of the power and authority by which ... private rights are lost or sacrificed.... The enactment of the federal statute authorizing [the federal Witness Protection Program] ... is the governmental action on which the Constitution operates .... ” Abood v. Detroit Board of Education, 431 U.S. 209, 218 n. 12, 97 S.Ct. 1782, 1791 n. 12, 52 L.Ed.2d 261 (1977) (quoting Railway Employes’ Department v. Hanson, 351 U.S. 225, 232, 76 S.Ct. 714, 718, 100 L.Ed. 1112 (1956)).
Expanding our field of vision somewhat, we observe that the defendant officials and Allen and his household also are involved in a symbiotic relationship. Not only are they joint participants in a program from which they all benefit, but the advantages reaped by each group are dependent upon the activities of the other. Thus Allen, Catherine, and the children obtain protection from retaliation by organized crime, and Catherine gains the ability, in practice, to keep the children for herself. The defendants (on behalf of the government in general) not only gain the testimony provided by Allen, but also benefit from the incentive, created by their demonstrated ability to shield Allen and his household, for other potential witnesses to come forward with evidence against organized crime. To some extent, moreover, that incentive is arguably strengthened by Catherine’s decision to deny William access to the children; the greater the government’s ability to portray the Witness Protection Program as one in which participants are free to start a completely new life, unfettered by any prior commitments, the more effective will be their effort to recruit other informants in the future.
Interdependence of the kind just described between the government and a private actor has been held to warrant attribution to the government of the conduct of the private party.43 This “joint-venture” doctrine derives partly from the principle that, having not only countenanced but benefited from behavior alleged to have infringed private interests, the state must accept responsibility for the injury.44 And partly it is founded on a recognition of the probable symbolic impact of such mutually beneficial activities; the state ought not to be permitted to disclaim responsibility for the consequences of conduct with which, in the eyes of the public, it appears to be intertwined. Both of these considerations are clearly applicable to the instant case.
*397Finally, we note that, in this case, the symbolic impact of the mutually beneficial activities is accentuated by the overt participation by government officials in the actions that resulted in the concealment of the children.45 Officers of the Marshals Service obviously were heavily involved in the initial relocation of Allen and his household and they have assisted in various ways in keeping their whereabouts secret. Through such participation, the defendants at least seem to have lent their imprimatur to all efforts by Allen or Catherine to cut themselves off from people who figured in their past lives. Such apparent ratification and support add to our willingness to subject the defendants’ conduct to constitutional scrutiny.
In short, many analytical roads lead to the same conclusion: the defendants are constitutionally accountable for the alleged injury to the plaintiffs.46 We now turn to that accounting.
III. Constitutionally Protected Interests
It is beyond dispute that “freedom of personal choice in matters of family life is a fundamental liberty interest” protected by the Constitution. Santosky v. Kramer, 455 U.S. 745, 753, 102 S.Ct. 1388, 1394, 71 L.Ed.2d 599 (1982)47 That freedom encom*398passes a wide variety of choices and activities: the decision to marry;48 procreation; 49 the use of contraception;50 the decision not to carry a child to term;51 and cohabitation with members of one’s extended family.52 Among the most important of the liberties accorded this special treatment is the freedom of a parent and child to maintain, cultivate, and mold their ongoing relationship.53
The constitutional interest in the development of parental and filial bonds free from government interference has many avatars. It emerges in a parent’s right to control the manner in which his child is reared and educated54 and in the child’s corresponding right not to have the content of his instruction prescribed by the state.55 It contributes heavily to a parent’s right to direct the religious upbringing of his child.56 And, above all, it is manifested in the reciprocal rights of parent and child to one another’s “companionship.”57
When asserted by a parent and child in a traditional nuclear family, the foregoing rights are acknowledged to be potent. It might be argued, however, that they are less formidable when asserted by a non-custodial parent — one who retains and regularly exercises “visitation rights” but who participates little in the day-to-day care and nurturing of his children.
To assess that argument we turn first to the case law. That inquiry unfortunately proves inconclusive; while the bulk of the pertinent precedent seems to suggest that we should not differentiate between custodial and noncustodial contexts when deciding what protections are constitutionally due a parent-child relationship, each of the germane cases has dealt with a factual situation or legal issue significantly different from the problem before us.
Dicta favorable to the plaintiffs may be found in Quilloin v. Walcott, 434 U.S. 246, 98 S.Ct. 549, 54 L.Ed.2d 511 (1978). Justice Marshall, speaking for a unanimous Court, seemed to imply that “a [once] married father who is separated or divorced from the mother and is no longer living with his child” could not constitutionally be treated differently from a currently married father living with his child. Id. at 255-56, 98 S.Ct. *399at 554 — 55.58 That suggestion is reinforced by some language in two of the Court’s decisions dealing with the procedural adequacy of state laws making possible the termination of interests of non-custodial parents. In Armstrong v. Manzo, 380 U.S. 545, 550, 85 S.Ct. 1187, 1190, 14 L.Ed.2d 62 (1965), the Court took for granted that the interest of a divorced father in the preservation of his visitation rights is a “liberty interest” sufficient to trigger the. application of procedural due process doctrine. And in Santosky v. Kramer, 455 U.S. at 749, 753-54, 102 S.Ct. at 1392, 1394, decided last term, the Court expressly held that the interest of a parent, who has temporarily lost custody of his child, in avoiding elimination of his “rights ever to visit, communicate with, or regain custody of the child” is important enough to entitle him to the procedural protections mandated by the Due Process Clause. The relevance of these two decisions to the instant case is limited by the fact that the establishment of a “liberty interest” sufficient to warrant application of procedural due process doctrine does not necessarily mean that that interest will be deemed “fundamental” and thereby entitled to the full panoply of substantive constitutional protections. Nevertheless, the Court’s willingness, in each ease, to assimilate the interests at stake to the rights enjoyed by custodial parents59 affords some support for the proposition that, for constitutional purposes, all (exercised) parental rights should be treated as equivalent.60
Some language inconsistent with that proposition may be found in the two decisions rendered by the Second Circuit in the only appellate case comparable to the one before us. In Leonhard v. Mitchell, 473 F.2d 709 (2d Cir.), cert. denied, 412 U.S. 949, 93 S.Ct. 3011, 37 L.Ed.2d 1002 (1973), a father in a position similar to that occupied by William sought a writ of mandamus compelling the Marshals Service to reveal to him the whereabouts of his children. The court ruled that, in view of a state’s “substantial range of authority to protect the welfare of children ... [which] extends to the determination of parental custody and visitation rights,” there is no “clear constitutional right to custody or visitation rights.” Id. at 713 (emphasis added). In Leonhard v. United States, 633 F.2d 599 (2d Cir.1980), cert. denied, 451 U.S. 908, 101 S.Ct. 1975, 68 L.Ed.2d 295 (1981), a subsequent damage action growing out of the same controversy, the court concluded “that the federal officials’ removal and concealment of the children on the consent of their mother and sole custodian, did not violate the children’s constitutional rights ... . ” Id. at 620.
*400However, the differences between the Leonhard cases and the suit before us are sufficiently marked that the foregoing comments bear only lightly on the question with which we are grappling. Most importantly, in Leonhard there was no suggestion that the Marshals Service was capable of arranging secret meetings between the father and the children without endangering anyone’s life; the court of appeals thus assumed that the defendants’ only option, if they wished to protect the children, was to deny the father access to them. In the first case, the court’s inquiry was further circumscribed by the nature of the remedy sought; presented with a stark choice between granting or denying an order that would reveal the location of the children, the court not surprisingly was reluctant to accord much weight to the plaintiffs’ constitutional claims. In the second suit, the court’s attention was deflected from the main issue by a different set of circumstances: the father’s constitutional claims were, by then, time-barred and the children had been returned to him. The only remaining relevant question was whether the children were entitled to damages for the violation of their rights during the period in which they had been denied the company of their father. The court concluded that the defendants, when deciding whether to reveal the location of the children, were entitled to rely on the (putatively reliable) judgment of the mother concerning what was necessary to ensure their safety. In this action, by contrast, a safe way of affording the father access to the children does exist, the question whether the defendants should make use of it is properly before us, and the mother’s awareness of the option undermines any presumption that she is acting solely in the best interests of her offspring. In short, the reflections of the Second Circuit are sufficiently intertwined with the idiosyncracies of the cases before it as to be of little moment in the present context.
To summarize, the balance of germane precedent inclines in favor of according similar constitutional status to custodial and non-custodial parent-child relations, but none of the cases is controlling. Consequently, to assess fairly the strength of the interests asserted by the plaintiffs in this case we must explore the concerns that underlie the constitutional protection traditionally accorded parental and filial bonds.
Three considerations account for the skepticism with which, when determining the constitutional validity of governmental action, we regard any interference with parent-child relations. The first is the important place such relations have long held in our culture. In the United States, parents historically have participated heavily in the rearing of their children.61 More importantly, persons in this country traditionally have believed that parents have a right to maintain contact with and shape the development of their children.62
*401The second factor consists of recognition that shielding relations between parents and children serves two complementary social functions. On one hand, it facilitates socialization of the children. We rely on parents to instill in their offspring the values and motivations necessary to develop them into “mature, socially responsible citizens.” 63 We assume that this is a function the state cannot effectively perform; only parents (or some close substitute) are sufficiently sensitive to the myriad, constantly fluctuating needs and drives of children to be able to provide them the combination of support and guidance necessary to prepare them for later life.64 Such preparation, in turn, is essential not only to enable each child to think and act independently when he comes of age,65 but to preserve and promote our system of government66 and our way of life.67 On the other hand, vesting in parents primary responsibility for the upbringing of children ensures the preservation of diversity and pluralism in our culture. As the Supreme Court explained long ago:
The fundamental theory of liberty upon which all governments in this Union repose excludes any general power of the State to standardize its children by forcing them to accept instruction from public teachers only. The child is not the mere creature of the State; those who nurture him and direct his destiny have the right, coupled with the high duty, to recognize and prepare him for additional obligations.
Pierce v. Society of Sisters, 268 U.S. 510, 535, 45 S.Ct. 571, 573, 69 L.Ed. 1070 (1925).68 The undesirability of cultural homogenization would lead us to oppose efforts by the state to assume a greater role in children’s development, even if we were confident that the state were capable of doing so effectively and intelligently.69 In short, our collective wish to preserve and promote the enlivening variety of our social and political life prompts us to be wary of any tampering with our highly decentralized, substantially unregulated, parent-dominated child-rearing system.70
*402The third consideration is our appreciation of the profound importance of the bond between a parent and a child to the emotional life of both.71 Frequently each party to the relationship depends heavily on his ties with the other for his sense of self-worth, for his very self-definition. To rephrase the point in the language of entitlements, a parent’s right to the preservation of his relationship with his child derives from the fact that the parent’s achievement of a rich and rewarding life is likely to depend significantly on his ability to participate in the rearing of his offspring.72 A child’s corresponding right to protection from interference in the relationship derives from the psychic importance to him of being raised by a loving, responsive, reliable adult.73
To determine the strength of the constitutional interests asserted in the instant case, we must access the relevance of the foregoing considerations to the plaintiffs’ relationship as it existed prior to the defendants’ alleged interference with it. We begin by asking what features distinguish the relationship between William and his offspring from the paradigmatic parent-child bond in a nuclear family. The answer turns upon a subtle distinction. It is well established that the strength and scope of constitutionally protected familial rights are not determined by the contours of state (or federal) law; what is important is the nature of the bond in question, not the way in which it has been categorized by a legislature or court. See Smith v. Organization of Foster Families, 431 U.S. 816, 845, 97 S.Ct. 2094, 2110, 53 L.Ed.2d 14 (1977) (dicta); Stanley v. Illinois, 405 U.S. 645, 651-52, 92 S.Ct. 1208, 1212-13, 31 L.Ed.2d 551 *403(1972).74 It is equally well established, on the other hand, that the state possesses substantial — and virtually exclusive — regulatory authority in the field of domestic relations. See Sosna v. Iowa, 419 U.S. 393, 404, 95 S.Ct. 553, 559, 42 L.Ed.2d 532 (1975). Thus, there is no question that the Pennsylvania court in the instant case had authority to vest in Catherine custody over the children and to award William no more (and no less) than visitation rights.75 What this means is that, for the purpose of weighing the plaintiffs’ constitutional interests, we should eschew inferences drawn from the manner in which the state describes their rights or deals with them in other contexts,76 but we must consider carefully the manner in which state law defines and limits William’s access to and responsibility for the children.
A nuanced analysis of the sort just indicated would require detailed knowledge of domestic relations law in Pennsylvania— specifically of the practical concomitants of the terms “custody” and “visitation rights.” We lack such knowledge and the parties have made little effort to educate us. For reasons that will become apparent, however, we believe that our inquiry may proceed upon two crude assumptions:77 (1) The non-custodial parent in a legally reorganized family generally spends considerably less time with his children than the custodial parent. (2) The custodial parent legally has the principal, if not exclusive, authority to make decisions regarding the child’s education, religious training, and discipline78 and, in practice, is usually the dominant force in the child’s upbringing, but the non-custodial parent (assuming he exercises his visitation rights) in most instances retains some influence over the child’s intellectual and moral development. On the basis of these rough generalizations, how should the reciprocal constitutional interests of a non-custodial parent and his children in one another’s companionship be measured?
The first of the three factors discussed above — the existence of a tradition of respect for the institution in question — provides us little guidance. It seems undeniable that recognition of the sanctity of the bond between a child and his non-custodial parent is far less firmly embedded in our cultural heritage than respect for the autonomy of the relations between a child and parent in a nuclear family. But that discrepancy is readily explainable on the basis of the relative rarity, in United States society in the past, of regularly exercised “visitation rights.” That situation is rapidly changing, however; the hegemony of the nuclear family is steadily being undermined. It has been predicted that the proportion of marriages fated to end in divorce will soon reach forty percent.79 In light of *404the fact that a divorced parent who is not granted custody is routinely awarded visitation rights,80 the result will be a large and growing number of children whose time and affection are divided between a custodial and a non-custodial parent81 In short, the institution of the “broken” family is becoming ever more socially important. To rely on the absence of a strong tradition of respect for one of the constituent relationships of that institution in determining its constitutional status seems senseless. Recognition of the need to adjust the meaning of the Constitution to conform to changes in- social life82 requires, in this instance, that we eschew reliance on history.
Reference to the second of the three factors is more productive of insight. Neither of the two complementary social functions fulfilled by traditional parent-child relations would appear to be specially dependent upon non-interference with the bond between a child and his non-custodial parent. Socialization of the children in such situations presumably can be adequately performed by the custodial parent (with or without the aid of a new spouse). And the values transmitted by a custodial parent are likely to be as distinctive as those transmitted by a non-custodial parent; vesting exclusive responsibility in the former for the child’s upbringing, consequently, would not affect the overall diversity of the society. These points should not be overstated. To the extent that a child remains emotionally dependent upon a non-custodial parent, cutting off his access to that parent will be painful and disorienting and will in some measure reduce his ability to absorb any system of values.83 But, on balance, it would appear that, insofar as our willingness to use the Constitution to shield parental and filial bonds from state interference derives from our recognition of the social needs served by those relations, we would be warranted in according diminished protection to the relation between a child and his non-custodial parent.
The force of the third consideration in the present context is somewhat harder to assess. The emotional importance of the bond between some parents and their children diminishes following the disintegration of the original family unit and the parent’s loss of custody.84 For others, however, the relationship remains important — even intensifies in response to the disruption or termination of other attachments.85 Moreover, there is considerable evidence that the emotional stability of children of divorced parents is often tied to the quality of their continuing relationships with their non-custodial parent86 On this point, in short, it appears impossible to say with any confidence that the concerns that underlie our willingness to accord “fundamental” status to parent-child bonds are any less telling when the relationship in question consists of mere “visitation.”
Our analysis thus far appears inconclusive. One of the two relevant factors suggests that the plaintiffs are entitled to only diminished constitutional protection; the other would place them on a par with parents and children in traditional settings. To choose between those options, we must examine more closely both the particularities of the case before us and the practical implications of attempting to differentiate it from a nuclear family.
*405We observe, to begin with, that the alleged “infringement” in this case is no mere disruption or curtailment of the parent-child relation but its permanent termination. Under these circumstances, the “emotional-attachments” consideration seems especially relevant and equally relevant to situations involving custodial and non-eustodial parents. Arguably, state regulation of, for example, a child’s education or religious upbringing threatens only moderately the emotional ties between the child and his parents — and is less likely significantly to affect the relations between the child and a non-custodial parent than the relations between the child and a custodial parent. Severance of the filial bond, on the other hand, obviously cuts deeply into the emotional interests of both parent and child— and may well be as painful and disorienting to a non-custodial parent as to one with whom the child enjoyed more frequent contact.
The foregoing generalization will not always hold. But to determine the severity of the emotional damage likely to be caused by any particular severance would be extremely difficult. The strength and psychic significance of a specific familial relation would be very hard to assess. Certainly no one objective index (such as frequency of visitation or degree of financial support) would be reliable. Moreover, the thorough inquiry necessary to make even a competent judgment of this sort would be time-consuming, degrading to the parties, and itself highly disruptive of the relationship in question.87
In light of these considerations, we conclude that the constitutional interests asserted by the plaintiffs are, in critical respects, roughly comparable to the interests of a parent and child in a viable nuclear family. We stress, however, that our analysis extends only to the question of the constitutional status of the right of a noncustodial parent and his or her children not to be totally and permanently prevented from ever seeing one another. In other words, we are considering here a narrow factual situation in which the government has acted to sever completely all ties between a non-custodial parent and his children without their participation or consent. In addressing this specific situation, we do not mean to suggest that a parent (or child) has a “fundamental right” to maintain visitation privileges in any particular way.
It is undisputed that the plaintiffs’ protected interests have been invaded. We have established that the defendants are constitutionally responsible for that invasion. See Part II. supra. We now turn to the question whether, on the facts as alleged in the complaint, the defendants can justify their actions and the effects thereof.
IV. Governmental Ends and Means
Rights of the sort asserted by the plaintiffs are not absolute; when incompatible with sufficiently potent public interests, they must give way. But such situations arise infrequently. Severance of the relationship between a parent and his child will survive constitutional scrutiny only if four requirements are met: (a) the asserted governmental interest must be compelling; (b) there must be a particularized showing that the state interest in question would be promoted by terminating the relationship; (c) it must be impossible to achieve the goal in question through any means less restrictive of the rights of parent and child; and (d) the affected parties must be accorded the procedural protections mandated by the Due Process Clauses.
These requirements, and the degree to which the defendants in the instant case have complied with each, are considered in order below. Our conclusion is that the plaintiffs have stated a cause of action in at least three of the four dimensions. We *406offer a relatively detailed analysis to explain our conclusion in the hope of preventing similar debacles in the future. Cases such as this can be avoided only through the promulgation of executive or congressional guidelines governing the administration of the Witness Protection Program that ensure the identification and accommodation of interests like those of the plaintiffs. The formulation of such guidelines may be difficult; the following discussion is intended to facilitate their development.
A.
The first and most important implication of our finding that the plaintiffs’ stake in one another’s companionship must be deemed a “fundamental liberty interest” is that the government must have a very good reason for abrogating their rights. Whatever may be the strength of the state interest necessary to justify a minor or moderate interference with their relationship,88 it is clear that permanent termination of their bond can be justified only by the promotion of a “compelling” objective.89
The defendants might point to two objectives in an effort to provide a compelling justification for their conduct in this case:90 promotion of the “best interests” of the *407children themselves or advancement of the public interest in the suppression of organized crime.
The first argument merits only brief attention. For two reasons, invasion of the plaintiffs’ protected interests cannot be justified on the basis of the government’s parens patriae interest in protecting the welfare of the children.91 First, the Supreme Court has made plain, albeit in dictum, that a government could not break up a “natural family” solely on the basis of a determination that the children’s “best interest” would be served thereby, absent a showing that the parents were “unfit” to care for their offspring. Quilloin v. Walcott, 434 U.S. 246, 255, 98 S.Ct. 549, 554, 54 L.Ed.2d 511 (1978) (quoting Smith v. Organization of Foster Families, 431 U.S. 816, 862-63, 97 S.Ct. 2094, 2119, 53 L.Ed.2d 14 (1977) (Stewart, J., concurring in the judgment)). The relations between William and his offspring are entitled to no less protection. See Part III, supra. Second, the only plausible basis for a justification related to the “best interests” of the children would be the possibility that their lives would be endangered if William were allowed to see them.92 That argument, however, is seriously weakened by the fact that the government itself must bear at least some responsibility for creating any such danger. By inducing Allen to come forward with evidence against leaders of organized crime, it has created a situation in which the children are potential targets of retaliation. Invasion of the plaintiffs’ rights should not be legitimated by the need to solve a problem the defendants themselves have generated.
The second argument available to the defendants is much more substantial. Organized crime, they might point out, is a serious problem in the United States today. Moreover, its very “organization,” and the code of secrecy by which its participants are bound, hamper the efforts of law enforcement agencies to obtain the evidence necessary to stop or curtail it. Evidence against organization leaders is particularly hard to come by. The police therefore must rely heavily on testimony provided by informants — people formerly or currently involved in organized criminal activity. Securing the aid of such persons is not easy; they are aware that by providing evidence against their former partners or employers, they place their own lives and the lives of their families in jeopardy. If the government were unable to guarantee their safety, they would rarely come forward. In sum, suppression of organized crime requires that the government be empowered, in its discretion, to relocate informants and members of their households and to maintain the secrecy of their new identities. And that, in turn, requires that the government be free, when it deems appropriate, to terminate contacts between witnesses or members of their families and people who figured in their past lives.
The foregoing justification clearly has some force. Whether it would be sufficient to warrant severance of the bond between a child and his natural parent we find it impossible, at this point, to say. Our inability to resolve this issue derives partly from the paltriness of the pertinent precedent. The lack of guidance afforded us by the case law results, in turn, principally from the frequency with which we and other courts have employed a convenient device for evading questions like that before us. Faced with a conflict between an important individual right and a powerful state inter*408est that allegedly Warrants infringement of the right, courts have been prone to hypothesize that the state’s objective would prevail if the challenged statute directly and effectively promoted it, and then go on to examine the closeness of the “fit” between the statute and the asserted objective — in general and in the case at bar. The usual conclusion is that the enactment, in fact, would do little to advance the asserted end. Its principal justification thus undercut, the enactment collapses when subjected to constitutional attack. See, e.g., Carey v. Population Services International, 431 U.S. 678, 690-91, 694-96, 97 S.Ct. 2010, 2018-19, 2021-22, 52 L.Ed.2d 675 (1977); Moore v. City of East Cleveland, 431 U.S. 494, 500, 97 S.Ct. 1932, 1936, 52 L.Ed.2d 531 (1977) (plurality opinion).93
In the following sections, we follow a similar analytical path.94 But, though that analysis suffices to decide the case before us, it leaves unresolved one important question likely to be presented in similar cases in the future (and thus that must be addressed by the draftsmen of guidelines for dealing with situations like this): if, in a particular instance, government officials demonstrate that the testimony of an informant is essential to the prosecution of an important leader of organized crime and that the interests of a non-custodial parent and members of the informant’s household cannot be accommodated without risking human life, may the government go ahead, accept the informant and his family into the program, and subsequently deny the parent access to the children?
Courts’ traditional reluctance to confront questions of this order means that we have very little to go on. We know, of course, that a state’s legitimate interests in protecting children’s welfare and in promoting the public health, safety, welfare and morals are sufficient to justify minor restrictions on parents’ control over the upbringing of their offspring. Wisconsin v. Yoder, 406 U.S. 205, 233,92 S.Ct. 1526, 1542, 32 L.Ed.2d 15 (1972) (dicta); Prince v. Massachusetts, 321 U.S. 158, 166-70, 64 S.Ct. 438, 442-444, 88 L.Ed. 645 (1944). And, if it can show that a parent is “neglectful” or otherwise unfit to care for a child, a state may sever the bond between the two. Stanley v. Illinois, 405 U.S. 645, 652, 92 S.Ct. 1208, 1213, 31 L.Ed.2d 551 (1972) (dicta).95 But there are few other features on this doctrinal map. Without any markings to assist us in getting our bearings, our answer to the aforementioned question might turn solely upon whether we felt that the suppression of organized crime was sufficiently important to be fairly described as “compelling.”
Any inclination we might have to speculate on that issue is dissipated by the paucity of relevant evidence in the record before us and the inconclusiveness of the data available from other sources. Observers and scholars continue to disagree not only over the likelihood that an informant will be “disciplined” by those he implicates96 *409(and thus the need for a Witness Protection Program), but also over the nature and scope of the activities conducted by organized crime97 and the seriousness of the threat that such activities pose to law-abiding citizens and to the integrity of our economic and political systems.98 Given the range of respectable opinions on these crucial issues, we must decline to say more than that the assessment of the relative strength of the government’s interest and the parent’s and children’s rights will be a difficult task for the body that ultimately must undertake it.
B.
Assuming, arguendo, that the government’s interest in the suppression of organized crime is sufficiently potent to justify invasion of constitutionally protected familial rights, the government may not rely on an irrebuttable presumption that its interest would be promoted in a given case, without affording the affected parties an opportunity to prove otherwise. Stanley v. Illinois, 405 U.S. 645, 657-58, 92 S.Ct. 1208, 1215-16, 31 L.Ed.2d 551 (1972).99 In part, this principle is an outgrowth of the doctrine of procedural due process.100 In part, it is a corollary of the doctrine of substantive due process:101 avoidance of any unnecessary infringement of fundamental rights requires that the government make a particularized showing of advantage in every case in which it contemplates depriving someone of constitutionally protected interests.102
*410In this case, there may have been such a particularized determination; the governing Justice Department Order instructs the Assistant Attorney General in charge of the concerned division to admit a witness and his household into the program only upon a finding that (among other things) admission “would be advantageous to the Federal interest.”103 But, putting aside for the moment the high risk of error in such an ex parte judgment made by an interested party,104 there is no indication in the record that the Assistant Attorney General was ever aware that induction of Allen, Catherine and the children would have the effect of terminating the relationship between the children and their natural father. The Constitution requires that there be more than a determination that the “Federal interest” would be marginally advanced by taking action in a particular case; there must be a showing that the governmental interest would be promoted in ways sufficiently substantial to warrant overriding basic human liberties. That requirement has not been met in this case.
C.
To justify restriction of constitutionally protected activity, the government must do more than show that such curtailment would promote, in a particular ease, compelling governmental interests.
[I]f there are other, reasonable ways to achieve those goals with a lesser burden on constitutionally protected activity, a State may not choose the way of greater interference. If it acts at all, it must choose “less drastic means.”
Dunn v. Blumstein, 405 U.S. 330, 343, 92 S.Ct. 995, 1003, 31 L.Ed.2d 274 (1972) (quoting Shelton v. Tucker, 364 U.S. 479, 488, 81 S.Ct. 247, 252, 5 L.Ed.2d 231 (1960)). This principle has been repeatedly reaffirmed when constitutionally protected familial rights have been threatened. See Carey v. Population Services International, 431 U.S. at 686, 97 S.Ct. at 2016; Doe v. Bolton, 410 U.S. 179, 194-95, 93 S.Ct. 739, 748-49, 35 L.Ed.2d 201 (1973); Roe v. Wade, 410 U.S. 113, 155, 93 S.Ct. 705, 727, 35 L.Ed.2d 147 (1973).
In this case, the defendants concede that they were and are capable of arranging secret meetings between William and the children.105 They acknowledge that such contacts would not jeopardize the safety of the children, Catherine or Allen. And, whatever may be the legal or equitable constraints on their ability, at this juncture, to demand that Catherine permit the children to see their father, it is beyond dispute that they had the authority, at the time they accepted Allen and his family into the program, to insist that Catherine agree to such an arrangement.106 There is no suggestion in the record that the defendants would have been unable to induce Allen to testify had they demanded that the rights of the plaintiffs be accommodated in the aforementioned manner. In short, the defendants apparently had ready access to a “less drastic means” for achieving their goals. Their decision not to avail themselves of that option was inconsistent with their duty under the Constitution.
D.
It is beyond dispute that
state intervention to terminate the relationship between [a parent] and [a] child must be accomplished by procedures meeting the requisites of the Due Process Clause.
Santosky v. Kramer, 455 U.S. 745, 753, 102 S.Ct. 1388, 1394, 71 L.Ed.2d 599 (1982) (quoting Lassiter v. Department of Social Services, 452 U.S. 18, 37, 101 S.Ct. 2153, 2165, 68 L.Ed.2d 640 (1981) (Blackmun, J., dissenting)).107 Conformity with the princi*411pies of procedural due process, in this context, serves three independent functions. First, by exposing to adversarial testing the government’s asserted rationale for its action, it reduces the likelihood of error — i.e., the risk that the government will act on the basis of what, in reality, is an insufficient justification.108 Second, it permits the adversely affected parties to inform the government of ways in which the government’s objectives might be achieved through means less restrictive of their rights. Third, it accords the affected parties some measure of dignity; it enables them to participate in and understand the process whereby their interests are assessed and, if necessary, restricted.109
It is clear that “the requisites of the Due Process Clause” were not satisfied in the instant case. The defendants have never provided William with any kind of notice or opportunity to be heard. The Constitution certainly requires that much.110
How much more the Constitution requires in situations like that before us is far from clear. Set forth below are some of the major considerations that must be taken into account when designing a system for dealing with cases of this sort. Formulation of the details we must leave to a body with greater knowledge than we possess of the ways in which the Witness Protection Program does or might operate.
We begin with the principle that,
[bjefore a person is deprived of a protected interest, he must be afforded opportunity for some kind of a hearing, “except for extraordinary situations where some valid governmental interest is at stake that justifies postponing the hearing until after the event.”
Board of Regents v. Roth, 408 U.S. 564, 570 n. 7, 92 S.Ct. 2701, 2705 n. 7, 33 L.Ed.2d 548 (1972) (quoting Boddie v. Connecticut, 401 U.S. 371, 379, 91 S.Ct. 780, 786, 28 L.Ed.2d 113 (1971)) (emphasis added). Holding the hearing before execution of the decision is particularly important where, as here, the deprivation of the protected interest might be irrevocable or might cause irreparable harm and where the decision will not turn on judgments that can sensibly be made on the basis of written submissions.111
At oral argument, the defendants’ counsel argued that the need for secrecy and speed in the admission of witnesses might make a pre-entrance hearing of any sort impracticable. In some cases that may well be true, but it appears that in the majority of cases the Attorney General’s office now informs the Marshals Service of a decision to admit an informant at least three work*412days prior to the scheduled pick-up.112 It seems to us not inconceivable that, sometime during those three days, a secret meeting might be held to hear and evaluate the government’s assertions of need and the objections and claims of the non-relocated parent.
In those instances in which holding such a hearing would truly be impossible, the requirements of the Due Process Clause would be merely suspended, not eliminated;113 as soon as practicable after the admission of the informant, a hearing would have to be held, at least to work out some accommodation of the rights of the children and the parent left behind.114
Envisioning what a pre-admission (or post-admission) hearing might look like is no easy task. The affected parties would be entitled to no more (and no less) than a hearing “appropriate to the nature of the case.” Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306, 313, 70 S.Ct. 652, 657, 94 L.Ed. 865 (1950). “[D]ue process is flexible and calls for such procedural protections as the particular situation demands.” Morrissey v. Brewer, 408 U.S. 471, 481, 92 S.Ct. 2593, 2600, 33 L.Ed.2d 484 (1972). The situation before us is so idiosyncratic that it is difficult to predict the kind of “process” that both would be workable and would fulfill the three functions described above. We are unable to do more than offer the following suggestions:
(1)The irrevocability of decisions to admit witnesses and their households, combined with the virtual impossibility of obtaining meaningful judicial review of such judgments, strongly suggests that those determinations should be made in accordance with a standard set of basic procedures, not processes developed and modified on a case-by-case basis. Compare Santosky v. Kramer, 455 U.S. at 757 & n. 9, 102 S.Ct. at 1396 n. 9 (procedural “rules of general application” necessary when appellate review would be insufficient to ensure “fundamental fairness”), with Lassiter v. Department of Social Services, 452 U.S. at 31-32, 101 S.Ct. at 2162 (procedures determined on a case-by-case basis suffice when appellate review would be an adequate check).
(2) This is not to say that those procedures should be highly formal; quite the contrary. The need for confidentiality and some measure of speed, combined with the value of encouraging the parties to speak freely with one another in working out a mutually satisfactory solution to their common problem, argues in favor of an informal setting. Some kind of neutral arbiter might have to be present, but the emphasis should be on negotiation and accommodation, not confrontation.
(3) In deciding more specific questions relating to the form of the proceeding— e.g., whether the parties should have a right to be represented by counsel, should be able to present or cross-examine witnesses, etc. —reference should be made to the three factors set forth in Mathews v. Eldridge, 424 U.S. 319, 96 S.Ct. 893, 47 L.Ed.2d 18 (1976), for the selection of a procedure that optimally balances the reduction of the risk of error and the burdensomeness of additional safeguards.115 Reliance on those con*413siderations should be tempered, however, by sensitivity to (a) the need to foster negotiation and compromise and (b) the importance of involving the non-reloeated parent in the decisionmaking process.116
Conclusion
For the foregoing reasons, the District Court’s decision that the plaintiffs failed to state a claim for which relief could be granted is reversed. The case is remanded for further proceedings consistent with this opinion.
Because of the posture in which the suit has appeared before.us, we express no opinion on the truth of the allegations in the complaint. We also decline to reach a host of other issues that further prosecution of the case may raise: the merits of the defendants’ various jurisdictional defenses; whether some or all of the defendants are immune from liability; and the form or measure of relief that might be appropriate. These are all matters that might be addressed on remand.
As to the propriety and utility of pressing onward in litigation, we venture our opinion that ultimate resolution of this controversy by a court may not be the ideal solution for any of the parties. As the disputants conceded at the outset, this case involves a conflict between several powerful, legitimate interests. Guided by the foregoing clarification of their respective claims, the parties are likely to be better able than a judge to work out an arrangement for reconciling — or at least compromising between — their various needs and desires.
With regard to the general problem presented by this case, we reiterate our plea that either Congress or the administrators of the Witness Protection Program develop a set of guidelines that would facilitate the detection and accommodation of interests like those of the plaintiffs.
Reversed and remanded.
